Premature infant feeding: role of diluted formula.

The role of half strength, double volume milk feeds for initiating feeding in preterm newborn infants was evaluated. Thirty eight premature infants were included in the study and divided into Groups A and B having 20 and 18 babies, respectively. Group A babies were fed half strength (10 cal/oz) formula feeds but the volume was doubled, while Group B babies were fed full strength formula feeds (20 cal/oz) with standard volume. A pre-set schedule was evolved for feed increments in the two groups. The amount of feeds was increased daily till a volume of 150 ml/kg/day was reached. The end point of the study was achieved when the caloric intake became 100 cal/kg/day. It was observed that Group A babies attained enteral energy intake of 100 cals/kg/day much earlier and experienced lesser complications, viz., persistent gastric aspirate and abdominal distension. They required intravenous supplementation for a shorter duration thus reducing the associated complications.

Immunogenicity and tolerance of H. influenzae type b, tetanus toxoid conjugate vaccine given concurrently or in combination.

The present prospective, open, controlled, randomised comparative trial was undertaken to evaluate the sero response and side effects of PRP-T Conjugate Vaccine (ACT-HIB) in infants and children aged 2 months and 16-24 months. Fifty four babies aged 2 months formed group A, 56 children aged 16-24 months formed group B. Groups A and B were further subdivided into two sub groups each destined to receive either PRP-T vaccine in association with DPT vaccine at different sites (I) or PRP-T and DPT both vaccines at the same site mixed in the same syringe (II). Group A received 3 doses at 2, 3 and 4 months of age and group B received one dose between 16-24 months. The Geometric mean titres of Anti PRP antibodies observed in primary immunisation schedule (A) and single dose vaccination schedule (B) were comparable and significantly higher to prevaccination titres. A serum anti PRP level of > 1.0 mcg/ml after immunisation is believed to correlate with long term protection. Ninety-six percent of infants in Group A and 98% in Group B achieved titres > 1.0 mcg/ml. The side effects were minimal, local and were comparable between the study and control groups, suggesting that PRP-T vaccine is highly immunogenic and well tolerated in Indian infants and children.

Seroconversion following killed polio vaccine in neonates.

The study was carried out to evaluate the efficacy of IPV in neonates and to study the additive effect of IPV or OPV at birth on seroconversion with three subsequent doses of OPV. Addition of IPV or OPV at birth to the conventional OPV schedule resulted in significantly higher seroconversion rates than in the controls, who received three doses of OPV. Three doses of IPV beginning from birth resulted in significantly better seroconversion rates than in the control group. Children receiving 3 doses of IPV showed significantly greater seroconversion rates against type III polio virus than those receiving IPV/OPV at birth followed by 3 doses of OPV. The difference in the seroconversion rates against the other virus types was not significant. A significantly greater number of children who received some vaccine at birth (IPV or OPV) were protected against poliomyelitis by 6 weeks age as compared to those who received no immunization at birth. The study recommends that seroconversion rates following three doses of IPV are satisfactory. Addition of IPV or OPV at birth to the conventional schedule markedly increases the seroconversion rates. Immunization can be started at birth to ensure early protection against poliomyelitis.

Hemostatic profile in septicemic neonates with and without bleeding.

Hemostatic profile was studied in 25 full term, non-asphyxiated neonates with blood culture-proven septicemia. Nine (36%) of these neonates manifested bleeding. Detailed coagulation tests and platelet studies were deranged in 24 (96%) of neonates with septicemia. Abnormalities in coagulation tests did not differ in those with and without bleeding. Only platelet aggregation with ADP was deranged to a significantly greater extent in those with bleeding as compared with those without bleeding.

Neonatal mechanical ventilation--experience at a level II care centre.

One hundred and fifty nine neonates were ventilated over a period of one year of whom 74 (46.54%) survived. This study aims to analyse the indications, complications and outcome of babies requiring mechanical ventilation. The early outcome measures were (i) survival rate with respect to birth weight, gestation and indication of ventilation, and (ii) Complications of assisted ventilation. One hundred and forty seven babies received IPPV and 34 received CPAP. Twenty two out of these 34 required IPPV later. Survival was cent percent on exclusive CPAP mode. HMD was the commonest indication for ventilation followed by Birth asphyxia, Apnea of prematurity, Meconium Aspiration Syndrome and Persistent Pulmonary Hypertension of the New born. Survival rates increased with increasing birth weight and gestational age, changing from 25% for < 1000 gm and 20% for < 28 wks to 53% for > 2500 gms and 50.2% for > 37 wks. Prolonged ventilatory support was needed for HMD (mean 114 hrs) and PPHN (mean 156 hrs). Commonest complication was Sepsis (26%) followed by Pulmonary hemorrhage, Pneumothorax and IVH. Lower success rates in ventilation is due to the poor survival of babies weighing < 1000 gms and those with a gestation of < 28 wks with nosocomial infections as a major complication of assisted ventilation being an additional factor.

Hemostatic profile in neonatal septicemia.

Hemostatic profile was studied in 25 full term non-asphyxiated neonates with blood culture-proven septicemia. Observations were compared with that of 25 healthy, non-asphyxiated, full term, birth weight and age-matched controls. Detailed coagulation tests & platelet studies were done in each of the 50 neonates by standard techniques. Hemostatic defects occurred in 96% of the septicemic neonates and none in the control group irrespective of the occurrence of clinical bleeding. The coagulation tests were deranged in 805 and platelet function tests in 92% of patients. These tests were significantly deranged in septicemic neonates as compared to control group.

Free oxygen radicals--predictors of neonatal outcome following perinatal asphyxia.

The study was undertaken to evaluate the role of free oxygen radicals in asphyxiated neonates. Thirty term neonates appropriate for gestational age and with severe birth asphyxia (Apgar score of 3 or less at 1 minute of life) formed the study subjects. The levels of superoxide dismutase (SOD), glutathione peroxidase (GPx), creatine phosphokinase (CPK) and lipid peroxidase (LPO) in the CSF of these neonates were estimated between 12 and 48 hrs of life. Enzyme estimation was performed by standard methods and the results were analysed statistically using Multivariate Logistic Regression analysis and non parametric tests namely Kruskal Wallis test and Wilcoxon's rank sum test. Out of the thirty babies, 14 were observed to be neurologically normal, 9 had significant morbidity and 7 died. The SOD levels ranged from 12.4 to 140 units/ml, GPx from 128 to 1933 nmol/min/dl, CPK from 2 to 2098 IU/dl and LPO from 5.4 to 30.8 umol/hr/dl. The SOD and GPx levels had an inverse relationship whereas rise in LPO and CPK levels were directly proportional to the extent of neurological damage and ultimate clinical outcome. CPK levels higher than 140 IU/ml were lethal and associated with 100% mortality whereas all normal neonates had CPK below 37 IU/ml. The levels of antioxidant enzymes can reliably and significantly predict mortality and morbidity whereas level of an enzyme cannot confidently confer normalcy. Hence antioxidant enzyme levels with a cut off value can be a useful marker and serve as a prognostic indicator in times to come.

End tidal carbon dioxide monitoring--its reliability in neonates.

End tidal Carbon dioxide monitoring was undertaken prospectively in all Ventilated neonates in our NICU admitted from March 1995 to August 1995 irrespective of the birth weight, gestational age and indication of ventilation. The aim was to determine the correlation between ETCO2 and PaCO2 in various clinical situations. The arterial blood gases were obtained in all ventilated babies with simultaneous and continuous ETCO2 monitoring and were analysed by AVL 995 Hb blood gas analyser. ETCO2 was analysed by side stream technique by Datex Cardiocap II monitor. A total of 152 samples from in-dwelling radial artery catheters were analysed from babies with birth weight from 900 g to 3400 g, gestation age from 28 to 42 wks and were ventilated for various indications like Severe Birth Asphyxia (SBA), Meconium Aspiration Syndrome (MAS), Recurrent Apnoea and Hyaline Membrane Disease (HMD). Statistical analysis was done in 10 groups to see if the ETCO2 correlated with its corresponding PaCO2 value. The study groups comprised three groups based on birth weight being < 1.5-2.5 kg and > 2.5 kg three groups as per the gestational age being 28-31+6 wks, 32-36+6 wks and 37-41+6 wks and four groups as per the need for ventilation being Severe Birth Asphyxia, Meconium Aspiration Syndrome, Apnoea of Prematurity and Hyaline Membrane Disease. Results of the correlation analysis revealed that the correlation coefficient in the study group ranged from 0.55 to 0.96 and was statistically significant in babies > 2.5 kg and 1.5-2.5 kg, in term and preterms 32-36 wks, and in babies with MAS, SBA and Recurrent Apnoea. The correlation coefficient was lowest in babies with HMD, being 0.55. The study showed that ETCO2 correlates closely with PaCO2 in most clinical situations in neonates and we recommend its use in all level III NICUs in ventilated babies.
