Objectives. Parenchymal involvement of intraventricular hemorrhage (IVH) is a major risk factor for neurodevelopmental handicap in very low birth weight neonates. Previous trials have suggested that indomethacin would lower the incidence and severity of IVH in very low birth weight neonates. Methods. We enrolled 431 neonates of 600- to 1250-g birth weight with no evidence for IVH at 6 to 11 hours of age in a prospective, randomized, placebo-controlled trial to test the hypothesis that low-dose indomethacin (0.1 mg/kg intravenously at 6 to 12 postnatal hours and every 24 hours for two more doses) would lower the incidence and severity of IVH. Serial cranial ultrasound examinations and echocardiographs were performed. Results. There were no differences in the birth weight, gestational age, sex, Apgar scores, and percent of neonates treated with surfactant between the indomethacin and placebo groups. Within the first 5 days, 25 (12%) indomethacin-treated and 40 (18%) placebo-treated neonates developed IVH (P = .03, trend test). Only one indomethacin-treated patient experienced grade 4 IVH compared with 10 placebo-treated neonates (P = .01). Sixteen indomethacin-treated neonates and 29 control neonates died (P = .08); there was a difference favoring indomethacin with respect to survival time (P = .06). Eighty-six percent of all neonates had a patent ductus arteriosus on the first postnatal day; indomethacin was associated with significant ductal closure by the fifth day of life (P < .001). There were no differences in adverse events attributed to indomethacin between the two treatment groups. Conclusions. Low-dose prophylactic indomethacin significantly lowers the incidence and severity of IVH, particularly the severe form (grade 4 IVH). In addition,indomethacin closes the patent ductus arteriosus and is not associated with significant adverse drug events in very low birth weight neonates.

Introduction: Failure or delay in spontaneous closure of ductus arteriosus is commonly seen among very low birth weight and very preterm neonates (<32 weeks), results in patent ductus arteriosus (PDA). Hemodynamically significant PDA (hs-PDA) is associated with significant morbidity and mortality if not timely intervened. At present, treatment modalities for hs- PDA remain pharmacological with nonspecific cyclo-oxygenase inhibitors such as ibuprofen/indomethacin or surgical ligation whenever pharmacological management is contraindicated. Recently, trials with prostaglandin synthase inhibitor, paracetamol are emerging as an effective treatment modality for PDA closure. In this retrospective observational cohort study, we evaluated the effectiveness of intravenous paracetamol as a first line therapy in very low birth weight infants with hemodynamically significant PDA. Methods: Twenty four preterm infants with hemodynamically significant PDA (hs-PDA) were treated with intravenous paracetamol 15mg/kg every 6 hourly and subsequent closure was evaluated clinically and by follow-up 2D-Echocardiography. The dosage of 15 mg/kg for IV paracetamol was chosen based on previously reported data for paracetamol in the treatment of PDA in preterm newborns. Results: PDA closure following intravenous paracetamol was evident in 22 preterm neonates (91.67%). There were no significant side effects noted with paracetamol therapy. Conclusions: This study concludes that intravenous paracetamol is an effective alternative for the pharmacological closure of hemodynamically significant patent ductus arteriosus in preterm infants.

Abstract Background The management of patent ductus arteriosus in preterm neonates continues to be a topic of discussion and controversy. Prolonged ductal patency in preterm neonates has been associated with significant short and long term morbidities and with increased mortality however, policy of routine treatment of all during neonatal period has failed to show significant improvement in long term outcome. Echocardiography has emerged as a promising modality to screen the newborns at risk of adverse effects of ductal shunting. This helps in identifying PDAs that require treatment to ultimately prevent unnecessary therapy or delay of necessary therapy. There are multitude of studies that have evaluated large number of echocardiographic markers for their predictive utility but only few have included all ductal markers together in a single study. The reported sensitivity (26-100%) and specificity (6-100%) of echocardiographic markers vary over a wide range. Thus, this study was planned with an aim to assess the predictive utility of all available ductal markers and their added advantage of having all over few ones in clinically apparent PDA in preterm VLBW newborns.Methods It was an observational prospective study conducted in tertiary care NICU at Lady Hardinge Medical College, Delhi. Fifty preterm very low birth weight (VLBW) newborns underwent four sequential Echo scans within first 72 hrs; first scan within 12 hours then at 24 hrs ,48 hrs and 72 hrs of age and were monitored clinically for the signs of PDA up to two weeks of life or discharge whichever comes later.Results The Ductal diameter, pulsatile ductal flow pattern, Left pulmonary artery (LPA) velocity, Left atrial to aortic width (La/Ao) ratio, Left atrial volume index (LAVI), Left ventricle to aortic width (Lv/Ao) ratio, E/A ratio and Left ventricular output/superior vena caval (LVO/SVC) flow ratio predicted clinically apparent PDA during first 72 hours of life.Conclusion This study provides insights into the predictive utility of other ductal echo markers along with the routinely measured conventional ones during first 72 hours of life in preterm VLBW newborns.
