4-AP 1 A small scale study was done on " Factors associated with neonatal hyperbillrubinemia on 25 neonate with clinical evidence of jaundice, 48 hours after delivery to four weeks of life. The factors associated with hyperbilirubinemia were premature rupture of membrane(40%), instrumental delivery (24%), use of oxytocin during labour(16%), neonatal infection (16%) maternal diseases e.g. jaundice and Rheumatic heart disease (12%), breech delivery (8%) prematurity (8%) meconium staining (8%) and smoking (4%). The result indicates an association between breast feeding and delayed feeding with neonatal hyperbilirubinemia.12 out of 25 babies were subjected to phototherapy. Among the phototherapy group there were 5 cases of instrumental delivery, 8 cases of abnormal situation, 2 cases prematurity and 8 cases in delayed feeding. The highest peak serum bilirubin level in blood was found in those babies, who were delivered by vaccum extraction. seven cases had clinical jaundice quite late after birth 1 Amniotic Membranes 1 Apamin 1 Bursting 1 Charybdotoxin 1 Emergency 1 Ethanol 1 Gastric Aspirate 1 Hyaline Membrane 1 Input membrane resistance 1 Leech 1 Maternal Morbidity 1 Membranes 1 Paroxysmal depolarization shift 1 Prediction 1 Premature Rupture 1 Preterm babies 1 Retzius nerve cells 1
