Breastfeeding practices of urban and rural mothers.

This longitudinal study was conducted to describe the prevalence of exclusive breastfeeding and factors influencing it in urban (tertiary care hospital of Delhi) and rural (First Referral Unit in Haryana) settings. The exclusive breastfeeding rates were 38%, 30%, 24%, 20%, 16% and 1% at discharge, 1.5, 2.5, 3.5, 4.5 and 6 months, respectively in the urban and; 57%, 16%, 9%, 6%, 5% and 0% at discharge, 1.5, 2.5, 3.5, 4.5 and 6 months, respectively in rural setting. Use of formula feeding was very high (55%) among the urban mothers during hospital stay. The factors associated with continuation of exclusive breastfeeding were mothers’ knowledge regarding breastfeeding and reinforcement by health professionals, whereas the factors associated with cessation were perceived insufficiency of milk, and cultural practices.

Determinant of Early Initiation of Breastfeeding in a Tertiary Neonatal Unit.

Introduction: Initiation of breastfeeding within one hour of birth is an important determinant of successful breastfeeding. National Family and Health Survey -3(NFHS-3) reported that only 23.4% of children <3 years were breastfed within one hour of birth. Objectives: the purpose of this study is to study the determinant of initiation of breastfeeding within one hour of birth. Setting: Tertiary –level neonatal unit. Material and Methods: All mothers admitted in in the postnatal ward were eligible for inclusion; mothers of sick and /or preterm infants were excluded. Enrolled mothers were interviewed between 24 and 72 hours after delivery. Results: The proportion of mothers who initiated breast feeding within one hour of delivery was 32%, between 1-6 hrs were 47% and between 6 to 48 hrs were 21%. Maternal age, education, socioeconomic status, occupation and antenatal or labor room counseling did not influence the initiation of breast feeding within one hour of delivery in univariate analysis. On multivariate analysis, admission in the general ward and delivery by caesarean section were found to be significantly associated with not initiating breastfeeding within one hour (adjusted ORs: 8.79, 2.48 to 31.08, p=0.001 and 6.79, 4.07 to 22.02 p=0.001 respectively). Only about 13% of the infants received prelacteal feeds. Conclusion: Mothers delivering by caesarean section or admitted in the general ward were at high risk of not initiating breastfeeding within one hour. Innovative strategies are required to ensure timely ignition of breastfeeding.

Efficacy of two dose regimes of intravenous immunoglobulin in Rh hemolytic disease of newborn--a randomized controlled trial.

OBJECTIVE: To compare the effect of two dose regimes of IVIg (0.5 g/kg vs. 1g/kg given soon after birth) on duration of phototherapy in Rh-isoimmunized neonates 32 week and above gestation. DESIGN: Randomized controlled trial. SETTING: Tertiary care hospital. SUBJECTS: Rh positive blood group neonates of gestation 32 weeks and above born to Rh negative mothers having positive Direct Coombs test and without any major malformation. INTERVENTION: Intravenous immunoglobulin (IVIg) infusion over 2 h either 0.5 g/kg (low dose group, n=19) or 1.0 g/kg (high dose group, n=19). PRIMARY OUTCOME VARIABLE: Duration of phototherapy. RESULTS: The mean duration of phototherapy was 77.3+/-57.2 h in low dose group versus 55.4+/-49 h in high dose group (mean difference=21.9; 95% CI-13.1 to 56.9). There was no difference in need for exchange transfusion (21% in both the groups) and requirement of packed red blood cells transfusion (12 transfusions in both groups). The duration of hospital stay was similar [8.4+/-6.9 and 13.6+/-14.8 days, respectively (mean difference=-5.1; 95% CI-12.8 to 2.5)]. No adverse effects of IVIg administration were noted. CONCLUSION: Two regimens of IVIg (0.5 g/Kg or 1 g/Kg) had comparable effect on duration of phototherapy, duration of hospital stay and exchange transfusion requirement, in Rh isoimmunized neonates of gestation 32 weeks and above.

Clinicoepidemiological profile and predictors of severe illness in young infants (< 60 days) reporting to a hospital in North India.

OBJECTIVES: To describe the clinical and epidemiological profile of young infants reporting to a hospital and assess previously proposed simple clinical signs for their value in enabling health workers to detect young infants with severe illness warranting hospital admission. METHODS: Observational study of infants less than 2 months of age presenting consecutively to a large public hospital in South Delhi who were evaluated by a health worker (nurse), on a standardized list of signs and symptoms, and the ability of these were evaluated against the need for hospital admission which was assessed by an independent pediatrician. RESULTS: Of the 1624 young infants triaged, 878 were enrolled into the study. Of these 100 (11%) were below 7 days of age, for whom the common reasons for seeking care were jaundice (52%), not feeding well (6%) and fever (5%). The remaining 778 (89%) were 7-59 days of age with respiratory symptoms as the main presenting complaints (29.1%). The primary clinical diagnoses in infants with serious illness needing admission to hospital in the age group <7 days (n = 66) were hyperbilirubinemia (56%) and sepsis (21%). In those between 7-27 days of age (n = 60), primary diagnoses were sepsis (27%), pneumonia (13%), diarrhea, dysentery or dehydration (10%), while in the age group 28-59 days of age (n = 47) pneumonia (40%), sepsis (19%) and diarrhea or dehydration (13%) were the common primary diagnoses. Signs that had at least a prevalence of 5% and were strong predictors for all the age categories studied were history of difficult feeding (OR 6.8 for 0-6 days, 15.1 for 2-27 days and 6.2 for 28-59 days age groups), not feeding well on observation (OR 13.7, 27.6 and 20.9 respectively for the 3 age groups), temperature > 37.5C (OR 21.8, 14.6 and 30.0 respectively for the 3 age groups) and respiratory rate > 60 per minute (OR 6.8, 15.1 and 21.0 respectively for the 3 age groups). Additional strong predictors with > 5% prevalence were history of convulsions (OR 7.9, only in 0-6 day age group), lethargy (OR 26.1, only in 7-27 day age group), and history of diarrhea (OR 3.0 for 2-27 days and 2.2 for 28-59 days age groups). CONCLUSIONS: Simple clinical signs are useful in hands of health worker for identifying neonates with serious illness warranting hospital admission. These will be of use in the further development of clinical algorithms for the national integrated management of childhood illnesses.

Incidence of periventricular leucomalacia among a cohort of very low birth weight neonates(< 1500 g).

BACKGROUND: Periventricular leucomalacia (PVL) is the most important neuropathologic lesion underlying major neuro-motor deficits of pre-term very low birth weight (VLBW) infants. Published data regarding PVL is not available from our country. OBJECTIVES: A study was planned with main objectives to estimate incidence and describe natural history of PVL among a very low birth weight cohort. STUDY DESIGN: A cohort study was performed on inborn VLBW babies over one year period at a tertiary neonatal intensive care unit. Serial weekly cranial ultrasounds were performed on 97 enrolled subjects until discharge, to diagnose and describe natural history of PVL. RESULTS: 31 out of 97 enrolled subjects developed PVL. No case of PVL developed beyond 19 days of postnatal life. Serial ultrasounds for each baby were tracked until discharge or death. Majority of lesions at onset were flares. Cysts tended to develop in over one third of cases during course of hospital stay. About 50% of ultrasound had normalized at discharge and sequelae such as cerebral atrophy and ventriculomegaly had appeared in few, the rest of lesions being either flares or cysts of PVL. CONCLUSIONS: PVL is fairly common among very low birth weight neonates. Ultrasonographic lesions of PVL undergo dynamic evolution from time of first detection to either progress, regress or leave sequelae before discharge. Ultrasound remains an important bedside diagnostic tool for PVL.

Early neonatal hyperbilirubinemia using first day serum bilirubin level.

OBJECTIVE: To evaluate the predictive value of total serum bilirubin (TSB) < or =6 mg/dl at 24 +/- 6 hr postnatal age in identifying near term and term infants, who do not develop hyperbilirubinemia subsequently. DESIGN: Prospective study. SETTING: Tertiary care hospital. METHODS: All healthy neonates with gestation > or =35 weeks, in absence of significant illness or Rh hemolysis were included. TSB was estimated at 24 +/- 6 hr by micromethod using spectrophotometry. Infants were followed up clinically every 12 hr till discharge and then after 48 hr. TSB level was estimated again whenever clinical suspicion of jaundice exceeded 10 mg/dl. Primary outcome was defined as presence of hyperbilirubinemia (TSB > or= 17 mg/dl) till day five of age. RESULTS: Of the 220 infants, 213 (96.8%) were followed up. All infants were exclusively breastfed. Mean age at bilirubin estimation was 24.7 +/- 1.9 hr with mean TSB of 5.9 +/- 1.8 mg/dl. Clinically detectable jaundice was present in 164 (77%) and hyperbilirubinemia occurred in 22 (10.3%) infants. A TSB level of < or = 6 mg/dl at 24 +/- 6 hr was present in 136 (63.8%) infants and only one infant developed hyperbilirubinemia subsequently (probability < 1%). In the remaining 77 (36.1%) infants, with TSB >6 mg/dl, subsequent hyperbilirubinemia developed in 21 (27.2%) (sensitivity 95%, specificity 70.6%, positive predictive value 27.2%, negative predictive value 99.3%, likelihood ratio of positive test 3.23 and likelihood ratio of negative test 0.07). Babies with TSB levels higher than 6 mg/dl had a significant risk of developing hyperbilirubinemia (relative risk 38; 95% confidence interval 6-1675). CONCLUSION: A TSB level of < or = 6 mg/dl at 24 +/- 6 hr of life predicted neonates who would not develop hyperbilirubinemia.

Minimal enteral nutrition.

Although parenteral nutrition has been used widely in the management of sick very low birth weight (VLBW) infants, a smooth transition to the enteral route is most desirable. Animal studies have shown that long periods of starvation are associated with mucosal atrophy and reduction of enzymatic activity. Studies have shown that giving small volumes of feeds frequently exerts a trophic effect on the gut mucosa. This concept has been termed as Minimal Enteral Nutriton (MEN). Clinical benefits of MEN include faster progression to full enteral feeds, lesser episodes of feed intolerance and reduction in hospital stay without a concomitant increase in the risk of necrotizing enterocolitis. MEN may be commenced in neonates on ventilation and total parenteral nutrition. A protocol for giving MEN has been described.

Fluid and electrolyte management in term and preterm neonates.

Disorders of fluid and electrolyte are common in neonates. Proper understanding of the physiological changes in body water and solute after birth is essential to ensure a smooth transition from the aquatic in utero environment. The newborn kidney has a limited capacity to excrete excess water and sodium and overload of fluid or sodium in the first week may result in conditions like necrotizing enterocolitis and patent ductus arteriosus. The beneficial effect of fluid restriction on the neonatal morbidity has been shown in multiple clinical trials. Simple measures like use of transparent plastic barriers, caps and socks are effective in reducing insensible water loss. Guidelines for the management of fluids according to birth weight, day of life and specific clinical conditions are provided in the protocols.

Management of infants with intra-uterine growth restriction.

Intra-uterine growth restriction (IUGR) and prematurity are the two causes for delivery of low birth weight infants. In India, IUGR contributes to almost two-thirds of infants in this category. Poor nutritional status and frequent pregnancies are common pre-disposing conditions in addition to obstetric and medical problems during pregnancy. Growth restriction may be symmetrical or asymmetrical depending on the time of insult during pregnancy. The pathological insult in an asymmetrical IUGR occurs during the later part of the pregnancy and has a brain-sparing effect. Common morbidities are more frequent in <3rd percentile group as compared to 3rd-10th percentile group. Guidelines for management of IUGR neonates in these two groups have provided in the protocols.

Post-resuscitation management of asphyxiated neonates.

Perinatal asphyxia is one of the common causes of neonatal mortality. Data from National Neonatal Perinatal database suggest that perinatal asphyxia contributes to almost 20% of neonatal deaths in India. Failure to initiate or sustain respiration after birth has been defined as criteria for the diagnosis of asphyxia by WHO. Perinatal asphyxia results in hypoxic injury to various organs including kidneys, lungs and liver but the most serious effects are seen on the central nervous system. Levene's classification is a useful clinical tool for grading the severity of hypoxic ischemic encephalopathy. Good supportive care is essential in the first 48 hours after asphyxia to prevent ongoing brain injury in the penumbra region. Strict monitoring and prompt correction is needed for common problems including temperature maintenance, blood sugars, blood pressure and oxygenation. Phenobarbitone is the drug of choice for the treatment of convulsions.

Sepsis in the newborn.

Systemic infection in the newborn is the commonest cause of neonatal mortality. Data from National Neonatal Perinatal Database 2000 suggest that Klebsiella pneumoniae and Staphylococcus aureus are the commonest causes of neonatal sepsis in India. Two forms of clinical presentations have been identified. Early onset sepsis, probably related to perinatal risk factors, usually presents with respiratory distress and pneumonia whthin 72 hours of age. Late onset sepsis, related to hospital acquired infections, usually presents with septicemia and pneumonia after 72 hours of age. Clinical features of sepsis are non-specific in neonates and a high index of suspicion is required for the timely diagnosis of sepsis. Although blood culture is the gold standard for the diagnosis of sepsis, reports are available after 48-72 hours. A practical septic screen for the diagnosis of sepsis has been described and some suggestions for antibiotic use have been included in the protocols.

Kangaroo Mother Care in very low birth weight infants.

OBJECTIVE: This study was conducted (i) to study through a randomized control trial the effect of Kangaroo Mother Care (KMC) on breast feeding rates, weight gain and length of hospitalization of very low birth neonates and (ii) to assess the acceptability of Kangaroo Mother Care by nurses and mothers. METHODS: Babies whose birth weight was less than 1500 Grams were included in the study once they were stable. The effect of Kangaroo Mother Care on breast feeding rates, weight gain and length of hospitalization of very low birth weight neonates was studied through a randomized control trial in 28 neonates. The Kangaroo group (n = 14) was subjected to Kangaroo Mother Care of at least 4 hours per day in not more than 3 sittings. The babies received Kangaroo Care after shifting out from NICU and at home. The control group (n = 14) received only standard care (incubator or open care system). Attitude of mothers and nurses towards KMC was assessed on Day 3 +/- 1 and on day 7 +/- 1 after starting Kangaroo Care in a questionnaire using Likert's scale. RESULTS: The results of the clinical trial reveal that the neonates in the KMC group demonstrated better weight gain after the first week of life (15.9 +/- 4.5 gm/day vs. 10.6 +/- 4.5 gm/day in the KMC group and control group respectively p < 0.05) and earlier hospital discharge (27.2 +/- 7 vs. 34.6 +/- 7 days in KMC and control group respectively, p < 0.05). The number of mothers exclusively breastfeeding their babies at 6 week follow-up was double in the KMC group than in the control group (12/14 vs. 6/14) (p < 0.05). CONCLUSION: KMC managed babies had better weight gain, earlier hospital discharge and, more impressively, higher exclusive breast-feeding rates. KMC is an excellent adjunct to the routine preterm care in a nursery.

Jaundice in the newborn.

Hyperbilirubinemia is the commonest morbidity in the neonatal period and 5-10% of all newborns require intervention for pathological jaundice. Neonates on exclusive breast-feeding have a different pattern of physiological jaundice as compared to artificially fed babies. Guidelines from American Academy of Pediatrics (AAP) for management of jaundice in a normal term newborn have been included in the protocol. Separate guidelines have been provided for the management of jaundice in sick term babies, preterm and low birth weight babies, for jaundice secondary to hemolysis and for prolonged hyperbilirubinemia. Although hour specific bilirubin charts are available, these have to be validated in Indian infants before they are accepted for widespread use.

Seizures in the newborn.

Seizures in the newborn period constitute a medical emergency. Subtle seizures are mild paroxysmal alterations in motor or autonomic activity and are unique to the neonatal period. They are likely to be missed or confused with benign movements observed commonly in preterm children. Focal clonic seizures have a better prognosis as compared to myoclonic seizures for long-term neuro-developmental outcome. Seizures due to sub-arachnoid hemorrhage and late onset hypocalcemia carry a better prognosis as compared to seizures due to hypoglycemia, meningitis and cerebral malformations. Hypoglycemia and hypocalcemia are common causes and should be excluded in all neonates with seizures. Multiple etiologies can co-exist in neonatal seizures and a comprehensive approach for management of neonatal seizures has been described.

Hypocalcemia in the newborn.

Healthy term babies undergo a physiological nadir in serum calcium levels by 24-48 hours of age. This nadir may be related to the delayed response of parathyroid and calcitonin hormones in a newborn. This nadir may drop to hypocalcemic levels in high-risk neonates including infants of diabetic mothers, preterm infants and infants with perinatal asphyxia. This early onset hypocalcemia which presents within 72 hours, requires treatment with calcium supplementation for at least 72 hours. In contrast late onset hypocalcemia usually presents after 7 days and requires long term therapy. Ionized calcium is crucial for many biochemical processes and total serum calcium is a poor substitute for the diagnosis of hypocalcemia.

Patent ductus arteriosus in preterm neonates.

Failure of the ductus arteriosus to close within 48-96 hours of postnatal age results in a left to right shunt across the ductus and overloading of the pulmonary circulation. This is more likely to happen in premature neonates with respiratory distress syndrome. Deterioration in the respiratory status on day 3-4 in a ventilated neonate and unexplained metabolic acidosis may be the earliest indicators of a patent ductus arteriosus (PDA). Indomethacin is the main stay of medical management of PDA in preterm neonates. Guidelines for administration of indomethacin have been described in the protocol. Restricted fluid therapy may be beneficial in the prevention of PDA in preterm neonates. Presence of PDA in a term neonate should be investigated to rule out an underlying congenital heart disease.

Hypoglycemia in the newborn.

Since a universal definition for hypoglycemia is lacking, an operational threshold for initiating therapy has been defined. Hypoglycemia is encountered in a variety of neonatal conditions including prematurity, growth retardation and maternal diabetes. Since hypoglycemia may be asymptomatic, routine screening for this condition in certain high risk situations is recommended. Supervised breast-feeding may be a treatment option in asymptomatic hypoglycemia. However, symptomatic hypoglycemia should always be treated with a continuous infusion of parenteral dextrose. Neonates needing dextrose infusion rates above 12 mg/kg/m should be investigated for refractory causes of hypoglycemia. Hypoglycemia has been linked to poor neuro-developmental outcome and hence aggressive screening and treatment is recommended.

Apnea in the newborn.

Apnea, defined as cessation of breathing resulting in pathological changes in heart rate and oxygen saturation, is a common occurrence in sick neonates. Apnea is a common manifestation of various etiologies in sick neonates. In preterm children it may be related to the immaturity of the central nervous system. Secondary causes of apnea should be excluded before a diagnosis of apnea of prematurity is made. Methylaxanthines and Continuous Positive Airway Pressure form the mainstay of treatment of apnea in neonates. Mechanical ventilation is reserved for apnea resistant to above therapy. An approach to the management of apnea in neonates has been described.
