CONCEPT, ASSESSMENT, GOALS, OBJECTIVES OF HIGH RISK NEWBORN INTRODUCTION A newborn should have a thorough evaluation performed within 24 hours of birth to identify any abnormality that would alter the normal newborn course or identify a medical condition that should be addressed (e.g., anomalies, birth injuries, jaundice, or cardiopulmonary disorders) . This assessment includes review of the maternal, family, and prenatal history and a complete examination. Depending upon the length of stay, another examination should be performed within 24 hours before discharge from the hospital.
The high-risk period begins at the time of viability (the gestational age at which survival outside the uterus is believed to be possible, or as early as 23 weeks of gestation) up to 28 days after birth and includes threats to Life and health that occur during The prenatal, perinatal, and postnatal periods.

extends from 7 to < 28 day.
DEFINITION OF HIGH RISK NEWBORN A newborn regardless of gestational age or birth weight, who has a greater – greater – than than average chance of morbidity or mortality because of conditions or circumstances superimposed on the normal course of events associated with birth and the adjustment to extrauterine existence. Encompasses human growth and development from the time of viability

CLASIFICATION OG HIGH RISK NEWBORN High-risk infants are most often classified according to birth weight, gestational age, and predominant pathophysiologic problems. The more common problems related to physiologic status are closely associated with the infant‘s state of maturity and usually usually involve chemical disturbances (e.g., hypoglycemia, hypocalcemia) and consequences of immature organs and systems (e.g., hyperbilirubinemia, respiratory distress, hypothermia).

INTENSIVE CARE FACILITIES FOR HIGH RISK NEWBORN Rapid advances in our understanding of the pathophysiology of the neonate and increased capacity to apply this knowledge have emphasized the need for appropriate settings in which to care for the seriously ill infant. Advancements in electronics and biochemistry, new methods for monitoring cardiorespiratory function, microtechniques for biochemical determination from minute quantities of blood, noninvasive monitoring, and new methods for assisted ventilation and conservation of body heat have made it possible to effectively manage the newborn with serious illness. Intensive care of the ill and immature newborn requires specialized knowledge and skill in a number of areas. Much of the equipment used in the care of the critically ill adult is unsuited to the singular needs of the very small infant; therefore equipment has been modified to meet these needs. Examples of modifications include ventilators that deliver small volumes of oxygen
29
in the proper concentration and pressure, infusion pumps that accurately deliver very small amounts, and radiant heat warmers that provide a constant source of warmth and allow maximum access to the infant. Most important, advances in intensive care have created a need for highly skilled personnel trained in the art of n eonatal intensive care. The diversity of special care needs requires that the unit be arranged for graduated care of the infant population. There should be adequate facilities and skilled personnel to provide one-toone nursing care for each seriously ill infant, as well as a means for graduation to one-to-three or one-to-four nursing care in a quieter area where infants require less intensive care until they are ready to be discharged to home. Family-centered care and a relatively quiet environment are often difficult to provide in a busy neonatal intensive care unit (NICU); therefore some units have developed step-down units and single room units where high-risk infants may be observed by skilled staff. Such areas are designed for family-centered care along with appropriate neuro developmental care.
ORGANIZATION OF SERVICES
The most efficient organization of services is a regionalized system of facilities within a designated geographic area. Neonatal intensive care facilities may provide three prescribed levels of care with special equipment, skilled personnel, and ancillary services concentrated in a centralized institution (American Academy of Pediatrics and American College of Obstetricians and Gynecologists, 2007):
30

TRANSPORTING HIGH-RISK NEWBORNS
When an at-risk infant is identified or anticipated, arrangements are made for care in the intensive care facility. The uterus is the ideal transport unit for the infant with anticipated difficulties; therefore, whenever possible, take the mother where special care is available for her delivery. Some infants develop difficulties after a seemingly normal pregnancy and uncomplicated labor. Because it is impossible to always predict when infants will require intensive care, a coordinated System is needed to ensure them an optimum opportunity for survival. Each hospital that delivers infants should be able to provide for appropriate neonatal stabilization and arrange for transport to a tertiary care facility.
31
The infant must be kept warm, be adequately oxygenated (including intubation if indicated), have vital signs and oxygen saturation monitored, and, when indicated, receive an intravenous (IV) infusion. The infant is transported in a specially designed incubator unit that contains a complete life-support system and other emergency equipment that can be carried by ambulance, van, plane, or helicopter. The transport team may consist of one or more of the highly trained persons from the NICU: a neonatologist (or a fellow in neonatology), a neonatal nurse practitioner, a respiratory therapist, and one or more nurses. The professional assigned to accompany the infant must be constantly alert to every change in the infant‘s condition and able to intervene appropriately. The neonate who must be moved from one place to another within the hospital (e.g., to surgery, or from delivery room to nursery) is transported in an incubator or radiant warmer and accompanied by the necessary personnel and equipment.

ASSESSMENT OF NEWBORN INTRODUCTION
At birth the newborn is given a cursory yet thorough assessment to determine any apparent problems and identify those that demand immediate attention. This examination is primarily concerned with the evaluation of cardiopulmonary and neurologic functions. The assessment includes the assignment of an Apgar score and an evaluation for any obvious congenital anomalies or evidence of neonatal distress. The infant is stabilized and evaluated before being transported to the NICU for therapy and more extensive assessment. A thorough, systematic physical assessment is an essential component in the care of the high-risk infant. Subtle changes in feeding behavior, activity, color, oxygen saturation (Spo2), or vital signs often indicate an underlying problem. The preterm infant, especially the ELBW infant, is not able to withstand prolonged physiologic stress and may die within minutes of exhibiting abnormal symptoms if the underlying pathologic process is not corrected. The alert nurse is aware of subtle changes and reacts promptly to implement interventions that promote optimum function in the high-risk neonate. The nurse notes changes in the infant‘s status through ongoing observations of the infant‘s adaptation to the extrauterine environment. Observational assessments of the high-risk infant are made according to the infant‘s acuity (seriousness of condition); the critically ill infant requires close observation and assessment of respiratory function, including continuous pulse oximetry, electrolytes, and blood gases. Accurate documentation of the infant‘s status is an integral component of nursing care. With the aid of continuous, sophisticated cardiopulmonary monitoring, nursing assessments and daily care can be coordinated to allow for minimum handling of the infant (especially the very low – birth-weight [VLBW] or ELBW infant) to decrease the effects of environmental stress.
35
The newborn requires thorough skilled observation to ensure a satisfactory adjustment to the extrauterine life. Physical assessment following delivery can be divided into 4 phases: 1. The initial assessment using an Apgar scoring system. 2. Transitional assessments during the periods of reactivity. 3. Assessment of gestational age. 4. Systematic physical examination.
INITIAL ASSESSMENT: APGAR SCORING
One significant assessment of the neonate is ‗APGAR SCORING‘ as described by DR Virginia Apgar. Despite its limitations, it is a useful quantitative assessment of neonate‘s condition at birth especially for the respiratory, circulatory and neurological status. Five objective criteria‘s are evaluated at one minute and five minutes, after the neonates body is completely born. The criteria‘s are respiration, heart rate/minute, muscle tone, reflex irritability and skin color. Each of these criteria is an index of neonates depression or lack of it at birth and is given score of 0,1 or 2. The scores from each of the criteria are added to determine the total score. The neonate is the best possible condition if the score is 10. Scores of 7-10 indicate no difficulty in adjustment in extrauterine life. Scores of 4-6 signify moderate difficulty and if the score is 3 or below, the neonate is in severe distress which must be treated immediately.

TRANSITIONAL ASSESSMENT: PERIOD OF REACTIVITY-
During the initial 24 hours, changes in heart rate respiration, motor activity, color, mucus production and bowel activity occurs in an orderly, predictable sequence that is normal and indicates lack of stress. F ir st peri peri od of r eactivity: activity: st
During the 1 30 minutes the infant is very active, alert, cries vigorously, sucks the fist greedily, and appears very interested in the environment. Neonate‘s eyes are wide open thus, is an excellent opportunity for mother, father and child to see each other.
37
Because the newborn has a vigorous suck this is the best time to begin breastfeeding.
Heart rate= 180/mt Respiration= 80/mt Bowel sounds are active. Second stage of first reactive period:
Lasts for 2-4 hours. Heart rate, respiration decreases. Temperature continues to decrease. Undressing and bathing is a voided during this time. Mucus production decreases. Urine and stool generally not passed. Baby in a state of sleep and is calm.
38
Second Second peri peri od of reacti reacti vity:
Lasts for next 2-5 hours. Heart rate and respirations increases. Alert and responsive. Gastric, respiratory secretions increased. Passage of meconium frequently. After this stage is a stage of stabilization of physiologic systems. ASSESSMENT OF GESTATIONAL AGE
One of the most satisfactory method for predicting mortality risks and providing guidelines for the management of newborn is the classification of infants at birth by both birth weight and the gestational age. Appropriate for gestational age Large for gestational age Small for gestational age
Assessment of gestational age is mandatory for all neonates for further management. Last menstrual period is important clue for calculation of gestational age, but it may not be reliable in menstrual irregularities or mother may not remember the exact date. The clinical assessment is more practically significant. Physical and neurological examinations are done to detect the gestational maturity.

Assessment of maturity of the neonates is fairly reliable on the basis of physical characteristics. But they are of limited value to assess the gestational age in less than 36 weeks of maturity. The neurological characteristics are more reliable for the precise assessment of maturity. The neurological assessment is performed based on four fundamental observations, i.e. muscle tone, joint mobility, certain automatic reflexes and fundus examination. The muscle tone of the newborn baby is assessed by three parameters, i.e. posture or attitude, passive tone [popliteal angle]and scarf sign and active tone [traction response and recoil] The joint mobility is less in preterm babies. A term baby has more flexible and relaxed joint. The degree of flexion at ankle and wrist [square-window] is limited due to stiffness of joints in early gestation. Certain auto9matic reflexes like moro reflex, papillary response to light, blink response to glabellar tap, grasp response, neck flexors, rooting reflex with coordinated suckling efforts are assessed to detect the specific age of gestational maturity based on appearance of these reflexes. The fundamental examination for disappearance of anterior vascular capsule of lens is done to assess the gestational age. In infants less than 28 weeks, the anterior capsule is completely vascularized and after 34 weeks of gestational life, the vessels are almost atrophied. This examination is difficult due to non-co-operation and photophobia of the neonate. With the scoring system of the neurological assessment the accurate estimation of gestational age can be done. New Ballard score is widely used. Neuromuscular maturity is assessed by the test like posture, square window [wrist], arm recoil, popliteal angle, scarf sign and heel to ear, using the new Ballard scoring system. Physical maturity is assessed with this system by the characteristics like skin, lanugo, planter surface, breast, eye/ear and genitals.
41
TESTS USED IN ASSESSMENT OF GESTATIONAL AGE: POSTURE:
With infant quite and in supine position, observe degree of flexion in arms and legs. Muscle tone and degree of flexion increase with maturity. Full flexion of the arms and legs=4 SQUARE WINDOW:
With thumb supporting back of arm below wrist, apply gentle pressure with index finger and third fingers on dorsum of hand without rotating infant‘s wrist. Measure angle between base of thumb and forearm. Full flexion (hand lies flat on ventral surface of forearm)=4 ARM RECOIL:
With infant supine, fully flex both forearms on upper arms, hold for 5 seconds; pull down on hands to fully extend and rapidly release arms. Observe rapidity and intensity of recoil to a state of flexion. A brisk return to full flexion=4 POPLITEAL ANGLE:
With infant supine and pelvis flat on a firm surface, flex lower leg on thigh and then flex thigh on abdomen. While holding knee with thumb and index finger, extend lower leg with index finger of other hand. Measure degree of angle behind knee (popliteal angle). An angle of less than 90 degrees=5 SCARF SIGN:
With infant supine, support head in midline with one hand; use other hand to pull infant‘s arm across the shoulder so that infant‘s hand touches shou7lder. Determine location of elbow in relation to midline. Elbow does not reach midline=4 HEEL TO EAR:
With infant supine and pelvis flat on a firm surface, pull foot as far as possible up toward ear on same side. Measure distance of foot from ear and degree of knee flexion (same as popliteal angle). Knees flexed with a popliteal angle of less than 10 degrees =4

SUBSEQUENT OR FOLLOW-UP ASSESSMENT IN THE NEONATAL PERIOD 43
Subsequent assessment is usually done, in institutional delivery, on the first day of birth, i.e. within 24 hours and within the time of discharge. Daily clinical evaluation should be done, between first day examination and the day of discharge. Daily clinical evaluation should be done, between first day examination and the day of discharge. But daily detailed examination is not necessary because it may introduce infections. First day examinations should include the followings: Gener al m easur ements :
For full term infant average head circumference = 33 and 33.5cm. Chest circumference= 30.5-33cm. Head to heel length= 48-53 cm Body weight= 2700-4000g. Vital signs :
Axillary temperature: 36.5 to 37.6 C( 97.7- 99.7F) Pulse: 120-140/mt Respirations: 30-60/mt Blood pressure: 65/41 mm of Hg

Palate examination (hard and soft palate )for closure.
Size of tongue: in relation to mouth normally does not extend much past the margin of gums. Excessively large tongue seen in congenital anomalies, such as cretinism and trisomy 21. Teeth: pre-deciduous teeth are found on rare occasions; if they interfere with feeding, they
may be removed. Epstein's pearls: small white nodules found on sides of hard palate (commonly mistaken
for teeth); regress in a few weeks. Frenulum linguae: thin ridge of tissue running from base of tongue along undersurface to
tip of tongue, formerly believed to cause tongue-tie; no treatment necessary. True congenital ankyloglossia (tongue-tie) is rare. Infections : thrush, caused by Candida albicans, may appear as white patches on tongue
and/or
insides
of
cheeks that do not wash away with fluids; treated with nystatin suspension. Neck
Examine the following:
Mobility : infant can move head from side to side; palpate for lymph nodes; palpate clavicle for fractures, especially after a difficult delivery.
Torticollis: appears as a spasmodic, one-sided contraction of neck muscles; generally from hematoma of sternocleidomastoid muscle; usually no treatment required.
Excessive skin folds may be associated with congen ital abnormalities such as trisomy 21.
Stiffness and hyperextension may be caused b y trauma or infection.
Clavicle for intactness.
Observe for masses such as cystic hygroma which is soft and usually seen laterally or over the clavicle. 46
Chest
Circumference and symmetry : average circumference is 12 to 13 inches (30 to 33 cm), approximately 2 cm smaller than head circumference.
Breast.
Engorgement may occur at day 3 because of withdrawal of maternal hormones, especially estrogen; no treatment required. Regresses in 2 weeks.
Nipples and areola less formed and pronounced in preterm infants.
Respirator y System
Rate normally between 40 to 60 breaths/minute; influenced by sleep-wake status, when last fed, drugs taken by mother, and room temperature.
Rhythm respirations may be shallow with irregular rhythm.
Breath sounds,determined by auscultation.
Cardiovascul ar System
Rate:normal between 110 to 160 bpm (80 to 110 normal with deep sleep); influenced by behavioral state, environmental temperature, medication; take apical count for 1 minute.
Rhythm:common to find periods of deceleration followed by periods of acceleration.
Heart sounds,second sound higher in pitch and sharper than first; third and fourth sounds rarely heard; murmurs common, majority are transitory and benign.
Pulses,examine equality and strength of brachial, radial, pedal, and femoral pulses; lack of femoral pulses indicative of inadequate aortic blood flow.
Cyanosis,examine for cyanosis. Acrocyanosis of distal extremities is common; record location of any cyanosis, color changes with time, and when crying.
Blood pressure,neonates who weigh more than 3 kg have systolic blood pressure between 60 to 80 mm Hg; diastolic, between 35 and 55 mm Hg. Blood pressure is usually higher in the lower extremities than in the upper extremities. Blood pressure assessment may not be conducted routinely on healthy neonates. Measurement of blood pressure is essential
47
for infants who show signs of distress, are premature, or are suspected of having a cardiac anomaly. Abdomen
Shape,cylindrical, protrudes slightly, moves synchronously with chest in respiration.
Distension may be caused by bowel obstruction, organ enlargement, or infection.
Palpate abdomen for masses; gap between rectus muscles is common; palpate liver and spleen.
Auscultate abdomen in all four quadrants for bowel sounds; usually bowel sounds occur an hour after delivery.
Kidneys palpate kidneys for size and shape.
Umbilical cord
Normally contains two arteries, one vein; single artery sometimes associated with renal and other congenital abnormalities.
Signs of infection around insertion into abdominal wall-redness, discharge.
Meconium staining,associated with intrauterine compromise or postmaturity.

Female
Genitalia
Labia majora cover labia minora and clitoris in full-term female infants.
Hymenal tag (tissue) may protrude from vagina,regresses within several weeks.
Vaginal discharge,white mucous discharge common; pink-tinged mucous discharge (pseudomenstruation) may be present because of the drop in maternal hormones; no treatment necessary.
48
Male
Full-term,testes in scrotal sac; scrotal sac appears markedly wrinkled due to rugae.
Edema may be present in scrotal sac if the infant was born in breech presentation; a frank collection of fluid in the scrotal sac is a hydrocele,regresses in approximately a month.
Examine glans penis for urethral opening,normally central; opening ventral (hypospadias); opening dorsally (epispadias); abnormally adherent foreskin (phimosis). o
Check for patent anus,infant should pass stool within 24 hours after delivery. If passed meconium in utero, patent anus has been established.
Back
Examine spinal column for normal curvature, closure, and pilonidal dimple or sinus; also for tufts of hair or skin disruptions that would indicate possible spina bifida. Examine anal area for anal opening, response of anal sphincter, fissures. M usculoskeletal System
Examine extremities for fractures, paralysis, range of motion, irregular position.
Examine fingers and toes for number and separation: extra digits, polydactyly; fused digits, syndactyly.
Examine hips for dislocation,with the infant in supine position, flex knees and abduct hips to side and down to table surface; clicking sound indicates dislocation (Ortolani's sign).
Asymmetrical gluteal folds also indicate congenital hip dislocation.
Examine feet for structural and positional deformities, ie, club foot (talipes equinovarus) or metatarsus adductus (inward turning of the foot).
Neur ologi c System
Neurologic mechanisms are immature anatomically and physiologically; as a result, uncoordinated movements, labile temperature regulation, and lack of control over musculature are characteristic of the infant.
49
Examine muscle tone, head control, and reflexes.
Two types of reflexes are present in the neonate:
Protective in nature (blink, cough, sneeze, gag),remain throughout life.
Primitive in nature (rooting/sucking, moro, startle, tonic neck, stepping, and palmar/plantar grasp),either disappear within months or become highly developed and voluntary (sucking and grasping)
BEHAVIORAL ASSESSMENT Response to Stimu lation
Neonates exhibit predictable, directed responses in social interactions with nurturing adults or in response to attractive auditory or visual stimuli. Sleepin g Pattern
Length of sleep cycles (REM, active and quiet sleep) changes with maturation of the central nervous system (CNS).
Quiet sleep should increase with time in relation to REM sleep. Neonates usually sleep 20 hours per day.
50
F eedin g Patter n
Most neonates feeds 6 to 8 times per day with 2 to 4 hours between feedings; establish fairly regular feeding patterns in approximately 2 weeks.
Caloric requirements are high,110 to 130 calories/kg of bod y weight daily.
Most digestive enzymes are present at birth.
Imperfect control of cardiac and pyloric sphincters; immaturity results in regurgitation.
Pattern of E limin ation
Stool
o
Meconium is usually passed in 24 hours.

Vasoconstriction. Nonshivering thermogenesis elicited by sympathetic nervous system in response to decreased temperature.
51
REFLEXES OF NEWBORN
PRIMITIVE REFLEX Primitive reflexes are reflex actions originating in the central nervous system that
are exhibited by normal infants but not neurologically intact adults, in response to particular stimuli. These reflexes disappear or are inhibited by the frontal lobes as a child moves through normal child development. These primitive reflexes are also called infantile, infant or newborn reflexes . ADAPTIVE VALUE OF REFLEXES
Reflexes vary in utility. Some have a survival value. A perfect example would be the rooting reflex, which helps a breastfed infant find the mother's nipple. Babies display it only when hungry and touched by another person, not when they touch themselves. There are a few reflexes that probably helped babies survive during human evolutionary past like the Moro reflex. Other reflexes such as sucking and grabbing help establish gratifying interaction between parents and infants. They can encourage a parent to respond lovingly and feed more 52
competently. They can also help parents comfort their infant because they allow the baby to control distress and the amount of stimulation they receive. ROOTING REF LE X
The rooting reflex is present at birth: it assists in breastfeeding, disappearing at around four months of age as it gradually comes under voluntary control. A newborn infant will turn his head toward anything that strokes his cheek or mouth, searching for the object by moving his head in steadily decreasing arcs until the object is found. After becoming used to responding in this way (if breastfed, approximately three weeks after birth), the infant will move directly to the object without searching.
Rooting reflex SUCKIN G REFL EX
The sucking reflex is common to all mammals and is present at birth. It is linked with the rooting reflex and breastfeeding, and causes the child to instinctively suck at anything that touches the roof of their mouth and suddenly starts to suck simulating the way they naturally eat. There are two stages to the action: Expression : activated when the nipple is placed between a child's lips and touches their palate.
They will instinctively press it between their tongue and p alate to draw out the milk. 53
Milking: The tongue moves from areola to nipple, coaxing milk from the mother to be
swallowed by the child. GRASP
This reflex is shown by placing finger or an object into baby's open palm, which will cause a reflex grasp or grip. If it is tried to pull away, the grip will get even strong. The palmar and plantar grasp usually disappears by 5-6 months and 9-12 months respectively.
Palmar gr asp reflex PLANTAR REFL EX
A plantar reflex is a normal reflex that involves plantar flexion of the foot (toes move away from the shin, and curl down. BABI NSKI REFLEX
An infant demonstrating the Babinski reflex: he opens his mouth when pressure is applied to both palms (8 seconds ). The Babinski reflex occurs in newborn babies, and describes varying responses to the application of pressure to both palms. Infants may display head flexion, head rotation or opening of the mouth, or a combination of these responses. Smaller, premature infants are more susceptible to the reflex. M ORO REFLEX
Also called the startle reflex, the Moro is usually triggered if baby is startled by a loud noise or if his head falls backward or quickly changes position. Baby's response to the moro will include spreading his arms and legs out widely and extending his neck. He will then 54
quickly bring his arms back together and cry. The moro reflex is usually present at birth and disappears by 3-6 months.
STARTLE REFLEX
The Moro reflex in a four-day-old infant: 1) the reflex is initiated by pulling the infant up from the floor and then releasing him; 2) he spreads his arms 3) he pulls his arms in; 4) he cries (10 seconds)
MORO REFLEX
55
WALK I NG/ STEPPI NG REFL EX
The walking or stepping reflex is present at birth; though infants this young can not support their own weight, when the soles of their feet touch a flat surface they will attempt to 'walk' by placing one foot in front of the other. This reflex disappears at 6 weeks as an automatic response and reappears as a voluntary behavior at around eight months to a year old
WALKING/STEPPING REFLEX TONIC NECK REFL EX
The tonic neck reflex, also known as asymmetric tonic neck reflex or 'fencing posture' is present at one month of age and disappears at around four months. When the child's head is turned to the side, the arm on that side will straighten and the opposite arm will bend (sometimes the motion will be very subtle or slight). According to researchers, the tonic neck reflex is a precursor to the hand/eye coordination of the infant. It also prepares the infant for voluntary reaching.
56
TONIC NECK REFLEX Opposite reaction Tonic Neck Reflex
A postural reaction, the asymmetric tonic neck reflex, or fencer response, is present at birth. To elicit this reflex, while your baby is lying on his back, turn his head to one side, which should cause the arm and leg on the side that he is looking toward to extend or straighten, while his other arm and leg will flex. This reflex usually disappears by 4-9 months. GALANT REFL EX
If your baby is on his stomach and you stroke neck to the spinal cord (paravertebral area) on his middle to lower back, it will cause his back to curve towards the side that you are stroking. This reflex is present at birth and disappears by 3-6 months. If the reflex persists past six months of age, it is a sign of pathology. The reflex is named after the Russian neurologist Johann Susman Galant.
57
SWIM MI NG REFL EX
An infant placed face down in a pool of water will begin to paddle and kick in a swimming motion. The reflex disappears between 4 – 6 months. Its survival function is to help the child stay alive if it is drowning so a care giver has more time to save it. DOLL’S EYE REFLEX
Eyes open on coming to sitting (Like a Doll's) Head initially lags Baby uses shoulders to right head position PROTECTI VE REF LE X
1. Soft cloth is placed over the babies eyes and nose 2. Baby arches head and turns head side to side 3. Brings both hands to face to swipe cloth away CRAWLI NG REFL EX
Newborn placed on abdomen Baby flexes legs under him and starts to craw PARACH UTE RESPONSE
This is a protective response that protects infant if he falls. Beginning at about 5-6 months, if an infant falls, he will extend his arms to try and 'catch' himself. PROPPI NG
Beginning at different ages, the propping responses help child learn to sit. The first is the anterior propping response, which begins at 4-5 months, and involves infant extending his arms when he is held in a sitting position, allowing him to assume a tripod position. Next, lateral propping, appearing at 6-7 months, causes him to extend his arm to the side if he is tilted. 58
Lastly, posterior propping, causing him to extend his arms backwards if he is titled backward. DAILY OBSERVATION OF NEONATES :
Neonates should be observed daily during hospital stay. Detailed examination is not necessary but mother and baby should be approached two times daily and informations should be collected from the mother (or caretaker) about the feeding behavior, vomiting, passage of stool and urine, sleep and presence of any problems. The neonates should also be assessed for hypothermia, respiratory distress, jaundice and superficial infections like conjunctivitis, umbilical sepsis, oral thrush and skin infection. The neonates should be monitored for the danger signs. Presence of these features indicates special attention, reevaluation and early interventions. The danger signs are:
Poor feeding, sucking and swallowing reflex.
Cold to touch or having rise in body temperature
Poor activity and poor response to stimulation
Excessive crying and irritability
Rapid respiration, more than 60 per minutes and presence of chest retractions
Blue discoloration of lips or tongue (central cyanosis)
Drooling of saliva or chocking during feeding or frothiness
Labored respiration or absence of respiration
Jaundice appears within 24 hours one extending to palms or soles
No urine within 48 hours and no meconium within 24 hours
Convulsions or abnormal movements
Bleeding from any site
Umbilical discharge
Superficial infections (pyoderma, abscess, oral thrush, conjunctivitis)
Diarrhea, vomiting and abdominal distension.

[email protected] Abstract OBJECTIVE:
To identify the newborns who should receive hearing evaluation by hearing screening in high risk newborns; to find and confirm the high risk factors of hearing disorders in high risk newborns. METHOD:
The first screening was performed by DPOAE. Newborns did not passed the first screening undertook second screening using DPOAE + ABR. and newborns did not passed the second screening received hearing evaluation. High risk factors of hearing loss were found by Logistic regression analysis.
72
RESULT:
Three hundred and twenty-seven cases were screened. The positive ratio in first screening was 37.0%. The positive ratio in second screening was 11.0%. Ten cases were diagnosed as hearing loss and the incidence of hearing loss was 3.39%. High risk factors of hearing loss were asphyxiation, very low born weight (<1,500 g) and head and neck abnormality. CONCLUSION:
(1) DPOAE combined with ABR is credible and feasible in hearing screening of high risk newborns. (2) High risk factors of hearing loss were asphyxiation, very low born weight (<1,500 g) and head and neck abnormality in this study.
2. LONG TERM NEUROLOGICAL OUTCOME OF HIGH RISK INFANTS Authors:
1. Selzer, S C 2. Lindgren, S D 3. Blackman, J A
Abstract:
Evaluated long-term neuropsychological outcome of 20 high risk infants with intracranial hemorrhage (ICH) during the neonatal period who appeared free of significant impairment through 30 months of age. This group was compared with a matched sample of 20 high risk infants without intracranial hemorrhage and a group of 70 children with no history of perinatal or chronic health problems. A comprehensive neuropsychological evaluation at age 5 revealed that the two high risk groups tended to perform at a lower level than the control group across most measures. However, the ICH group performed at a significantly lower level than the control group on measures of perceptual-motor skills and intermodal memory abilities while the high risk group without ICH did not. The implications of differences in level and pattern of performance are discussed along with the implications of the current findings for long-term functioning of high risk infants with ICH.

SUMMARY High-risk neonates may be defined as newborns, regardless of gestational age or birth weight, who have a greater than average chance of morbidity or mortality because of conditions or circumstances superimposed on the normal course of events associated with birth and adjustment to extrauterine existence. Identification of high-risk newborns may occur during any of the following stages: prenatal, natal, or postnatal. High-risk infants may be classified according to birth weight, gestational age, and morbidity factors. Meeting the high-risk infant‘s nutritional needs requires specific knowledge of physiologic characteristics, the infant‘s particular needs, and methods of feeding. Delayed development in high-risk neonates is a concern; developmental interventions are individualized to ameliorate the effects and increase infant well-being. Parental involvement in the care of high-risk infants is important, and nurses should encourage parent-infant relationships from birth to discharge. Prematurity accounts for the largest number of admissions to an NICU. Nurses play an important role in end-of-life care of the family of the dying infant.
74
CONCLUSION Some newborns are considered high risk. This means that a newborn has a greater chance of complications because of conditions that occur during fetal development, pregnancy conditions of the mother, or problems that may occur during labor and birth. Some complications are unexpected and may occur without warning. Other times, there are certain risk factors that make problems more likely. Fortunately, advances in technology have helped improve the care of sick newborns. Under the care of specialized physicians and other healthcare providers, babies have much greater chances for surviving and getting better today than ever before.
