Evaluation of Rh-Hemolytic Disease in Neonates and Management with Early Intensive Phototherapy in the Neonatal Intensive Care Unit.

BACKGROUND OF THE STUDY: In neonates with Rh-hemolytic disease, light emitting diode (LED) phototherapy allows delivery of high spectral irradiance (SI). A linear correlation exists between SI and efficacy of phototherapy with no saturation point. There is scant data on evaluation and early phototherapy using LED units in Rh-hemolytic disease. OBJECTIVE: This study aimed to describe the hemoglobin (Hb), hematocrit (Hct), total serum bilirubin (TSB), phototherapy parameters and short-term outcomes in neonates with Rh-hemolytic disease. METHODOLOGY: Maternal parameters for Rh-isoimmunization were recorded and monitoring of fetal anemia by Doppler ultrasound was done. Early intensive phototherapy within 1 h of birth was initiated for cord blood Hb below 13.6 g/dl and/or TSB greater than 2.8 mg/dl. RESULTS: Fifty Rh positive neonates were enrolled of which 11/50 (22%) received intrauterine transfusions. The maximum TSB remained below 18 mg/dl in 42/50 (84%) of neonates. The mean SI on the trunk was 56.260 ± 8.768 µW/cm2/nm and duration of phototherapy was 7 ± 3.29 days (mean ± SD). There was a positive correlation between strength of indirect antiglobulin test and cord blood Hb: correlation coefficient (r) = 0.295; direct antiglobulin test and duration of phototherapy: r = 0.331. Early packed red blood cell (PRBC) transfusion was required in 8/50 (16%) neonates while 20/50 (40%) required late transfusions. CONCLUSION: With a mean SI of 56.260 ± 8.768 µW/cm2/nm on the trunk, TSB remained below 18 mg/dl in majority thereby avoiding exchange transfusion. Early or late PRBC transfusion requirement was 1 (1-2) (median ± interquartile range).

Proportionate Postnatal Growth in Preterm Neonates on Expressed Breast Milk Feeding With Selected Fortification.

BACKGROUND: Preterm neonates not fed an exclusive human-milk diet in the neonatal intensive care unit (NICU) show disproportionate postnatal growth. There are scant data on postnatal growth in neonates from India fed an exclusive expressed breast milk (EBM) diet. This study describes the postnatal changes in weight, length, and head circumference in preterm neonates given EBM with selected fortification. METHODS: The study had a prospective observational design. Exclusive EBM feeding, early initiation, and standardized progression of feeds was followed. Fortification of breast milk with human milk fortifier (HMF) or liquid calcium phosphate and multivitamins (CALVIT) or hindmilk (HM) was done based on the gestational age. Monitoring for weight, length, and head circumference was done from admission to discharge. RESULTS: Ninety-three preterm neonates were included in the study, of which 34 (36.6%) were small for gestational age. Thirty-two (34.3%) neonates received EBM with HMF, 35 (35.7%) received EBM fortified with CALVIT and 26 (28%) neonates received HM fortification. There was a significant difference in the change in z-scores from birth to discharge for the weight, length, and head circumference (P = .001). The mean increase in daily weight ranged from 8.8 to 9.5 g/d, whereas weekly change in length was 0.8-0.9 cm/wk, and head circumference was 0.7 cm/wk. CONCLUSION: Postnatal growth of preterm neonates during NICU admission on exclusive EBM feeding with selected fortification resulted in a proportionate increase in weight, length, and head circumference.
