AIM: We aimed to investigate fetal cardiac output (CO) in pregnancies with preterm premature rupture of membranes (PPROM) and its relationship with umbilical cord pH.
METHODS: This was a prospective study in total 90 pregnancies at 24-37 weeks gestation including 42 pregnancies with PPROM and 48 that healthy controls. Fetal cardiac function including combined, left and right CO z-scores were compared. The neonates in the PPROM group were separated with umbilical cord pH above and below 7.25, and cardiac output was compared between groups.
RESULTS: In PPROM group, CCO z-score, left cardiac output (LCO) z-score, and right cardiac output (RCO) were significantly lower compared to healthy pregnancies (p = .036, p = .001, p = .032, respectively), while RCO z-score showed no significant differences between the two groups. The aortic annulus and pulmonary artery annulus z-scores were measured smaller in the PPROM group (p = .000 and p = .001, respectively). In PPROM group, the fetal LCO z-score was significantly lower in neonates with an umbilical cord pH of 7.25 or less (p = .048).
CONCLUSION: This study provides evidence that fetal CCO is lower in PPROM compared with healthy pregnancies. Reduced LCO z-scores may be useful for predicting adverse neonatal outcomes in pregnancies with PPROM.
