Objective: Identify echocardiographic parameters at p4 day postnatal that predict the subsequent need for closure of a clinically significant patent ductus arteriosus (sPDA) in extremely-low-birth-weight neonates (ELBW).Study Design: Serial echocardiograms obtained in 115 ELBW at p10 day postnatal were examined to estimate PDA size using the PDA:left pulmonary artery (LPA) diameter ratio: X1 indicated a large PDA, <1 but X0.5 moderate, and <0.5 small. Sensitivity, specificity, and positive predictive values (PPV) were determined for ELBW <27 weeks and X27 weeks gestational age.Result: Neonates with moderate to large PDA at p4 day had 15-times greater likelihood of requiring treatment for sPDA than those with a small PDA (95% confidence interval (CI): 5.6-41). Sensitivity, specificity and PPV of the PDA:LPA at <27 weeks was 80, 86 and 92%, respectively.
Conclusion:A moderate to large PDA determined from the PDA:LPA ratio at p4 day postnatal identifies neonates <27 week gestation who subsequently require closure of a PDA.
patients admitted to the AICU, 30.5% died, 69.0% were transferred to another unit, and 0.5% were discharged. Conclusion The findings showed high compliance of AST at admission but low compliance at discharge, which needs further enforcement. Although the acquisition of CRKP was only 3.4%, it represents adding almost double (1.8) new cases of CRKP to the admission level. Future research is required to assess the impact of AST on the burden of healthcare-associated infections.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
