Abstract
To find association between fetal urine production rate (FUPR) and fetal inflammatory response syndrome (FIRS) in preterm premature rupture of membranes (PPROM). A prospective cohort study of 70 pregnant women with PPROM at 28-34weeks of pregnancy was conducted. FUPR was calculated by performing serial fetal bladder volume measurements ultrasonographically and was repeated weekly until delivery. After delivery, cord blood interleukin-6 (IL-6) levels were measured. Placental tissue histopathology was performed and neonatal outcomes were noted. Out of 70 recruited patients with PPROM, 44 had evidence of FIRS (62.86%). Mean FUPR at the time of delivery was significantly reduced in neonates with evidence of FIRS compared with the Non-FIRS group (13.89±8.06ml/h vs. 25.89±4.94ml/h). Out of 41 patients with reduced FUPR, 39 neonates had FIRS whereas only five out of 29 neonates with normal FUPR had FIRS (P<0.001). Severe neonatal morbidity was found in 24 out of 41 (58.54%) neonates with reduced FUPR prenatally. The occurrence of respiratory distress syndrome, necrotizing enterocolitis, and sepsis was significantly high in neonates with reduced FUPR. Reduced FUPR is strongly associated with FIRS in cases of PPROM and hence can be used as an early predictor of adverse neonatal outcomes.
