Preterm premature rupture of membranes (PPROM) can result in fetal complications such as oligohydramnios. This study aimed to determine the effects of intravenous (IV) fluid bolus on amniotic fluid index (AFI) in pregnant women with PPROM.
24 women with PPROM during singleton live pregnancy of 28 to 34 weeks whose baseline AFI was ≤ 5cm were randomized into two groups. The study group received one liter intravenous fluid bolus of isotonic Ringer serum during 30-minute period. Reevaluations of amniotic fluid index in both groups were made 90 minutes and 48 hours after baseline measurement. Independent t-test and paired t-test were used to compare the two groups and mean amniotic fluid index before and after treatment, respectively.
The results of this study demonstrate that AFI decreased statistically significant in both the control and study groups. AFI decreased in both groups at 48 hours later. This decrease was not statistically significant in any group. The mean change in AFI (90 minutes and baseline) and (48 hours and baseline) between the two groups were not significant. The time between mean baseline measurements and delivery were 196.41 and 140.58 hours in the study and control groups, respectively. This difference was not statistically significant.
This study did not find significant impact of hydration On AFI as a prophylactic method on oligohydramnios in pregnant women with PPROM.
胎膜早破(PPROM)可导致胎儿并发症,如羊水过少。本研究旨在确定静脉推注液体对PPROM孕妇羊水指数(AFI)的影响。
24名单胎活产、孕周为28至34周且基线AFI≤5cm的PPROM孕妇被随机分为两组。研究组在30分钟内接受1升等渗林格氏液静脉推注。两组在基线测量后90分钟和48小时重新评估羊水指数。分别使用独立t检验和配对t检验比较两组以及治疗前后的平均羊水指数。
本研究结果表明,对照组和研究组的AFI均有统计学意义的下降。两组在48小时后AFI均下降。但在任何一组中,这种下降均无统计学意义。两组之间AFI(90分钟与基线)和(48小时与基线)的平均变化无显著差异。研究组和对照组从平均基线测量到分娩的时间分别为196.41小时和140.58小时。这种差异无统计学意义。
本研究未发现补液作为预防PPROM孕妇羊水过少的方法对AFI有显著影响。
