RESUMO
Background: Neonatal hyperbilirubinemia continues to be the most common cause of hospital admissions and readmissions in the neonatal population worldwide and this pattern continues despite attempts to identify neonates at risk of pathological hyperbilirubinemia. The aim of the study was to determine the clinical profile and etiology in neonates who were treated with double volume exchange transfusion (DVET).Methods: This was a hospital based prospective observational study in neonates ?35 weeks of gestation who were treated with DVET for severe hyperbilirubinemia in a tertiary care centre over a period of six months.Results: In our study 110 neonates with severe hyperbilirubinemia were treated with DVET. Majority of the neonates were males (59.1%). Lower segment caesarean section (LSCS) was the common mode of delivery observed in 66.4% of the study subjects. Rh incompatibility (36.4%) was the commonest cause of exchange transfusion followed by ABO incompatibility (20%). The mean age of neonates at admission and mean age at DVET in days were 4.03�46 and 4.25�44 respectively. The mean birth weight of neonates treated with DVET was found to be 2.81�57. The mean total serum bilirubin at pre-exchange and post exchange were 26.13�58 mg/dl and 11.63�24 mg/dl respectively.Conclusions: Rh incompatibility was the most common cause in neonates with severe hyperbilirubinemia requiring double volume exchange transfusion.
RESUMO
Background: Double volume exchange transfusion (DVET) for severe unconjugated hyperbilirubinemia has become less common events now days in pediatric practices. But kernicterus is still common in low income country like India. The aim of the study was to determine the clinical profile and outcome in neonates who were treated with DVET.Methods: This was a retrospective study in neonate's ?34 weeks of gestation that were treated with DVET for severe neonatal hyperbilirubinemia over a period of four years.Results: In our study, 37 neonates underwent DVET. Male neonates (62.13%) and normal vaginal delivery (NVD) (70.2%) are common. ABO Isoimmunisation was commonest cause (56.75%) of exchange transfusion.' The mean TSBR at pre exchange and Post Exchange were 27.39 ' 5.99mg/dl and 15.16 ' 4.00mg/dl (p<0.05). Ten neonates (27%) among 37 neonates required twice DVET.Thrombocytopenia14 (37.83%); Seizure 5(13.5%) and Hypocalcaemia 3(8.1%) were common complication noted among total 17 (45.94%) neonates. BIND occurred in 15 neonates (40.5%) at the time of admission and seven (18.9%) neonates had persistent neurological abnormality at discharge. Neonate with BIND had early onset of jaundice (44.13'15.37 hours vs. 61.22'28.23hrs, p<0.05), with' higher' pre exchange TSBR value(28.96 '8.5mg/dl vs. 26.22'3.17mg/dl). Neonates admitted with BIND had higher percentage of persistent encephalopathy (40% vs. 4.5%,p<0.05), abnormal tone (33.3% vs. 4.5%,p<0.05), abnormal feeding (33.3% vs. 4.5%,p<0.05) and abnormal posture (26.6% vs. 0%,p<0.05)' at discharge as compared to those without BIND. No death occurred in this study population.Conclusions: Early detection and aggressive therapy with DVET can prevent neonates from brain injury.
