Prevalence, risk factors, severity and outcome of neonatal thrombocytopenia.

Abstract

Objective: To find out prevalence, risk factors, severity and outcome of neonatal thrombocytopenia (TCP). Study Design: Prospective Observational study. Setting: Neonatal Intensive Care Unit (NICU) of Children Hospital Complex Multan. Period: January 2020 to January 2021. Material & Methods: A total of 191 neonates admitted to NICU during the study period were enrolled. A special proforma was designed to record all study information while SPSS version 26.0 was utilized for data analysis. Prevalence of TCP was noted among neonates admitted in NICU during the study period. Maternal risk factors, neonatal risk factors, severity of TCP and outcome were recorded. Results: In a total of 191 neonates, 110 (57.6%) were male while overall mean age was recorded to be 2.98+2.46 days. The prevalence of TCP was recorded to be 47.1% (90/191). Pregnancy induced hypertension (p=0.0003), premature rupture of membrane (p=0.0105) and eclampsia (0.0215) were found to have significant association with the presence of TCP. Preterm neonates (p<0.0001), small for gestational age (p<0.0001), sepsis (p<0.0001) and nectrozing enterocolitis (p=0.0014) were found to have significant association with TCP. A total of 13 (6.8%) neonates died, out of which, 5 (38.5%) were having severe TCP. Conclusion: Prevalence of neonatal thrombocytopenia at neonatal intensive care unit was found to be high (47.1%). Pregnancy induced hypertension, premature rupture of membrane and eclampsia were found to have significant association with neonatal thrombocytopenia. Preterm, small for gestational age, sepsis and necrotizing enterocolitis were noted to be significantly associated with neonatal thrombocytopenia. Severe thrombocytopenia was noted to be a significant predictor of poor outcomes.
