Fetal distress (FD) is one of the most frequent causes of emergency cesarean section (CS) due to the insufficient uteroplacental blood supply during labor. There is a theory that Sildenafil citrate (SC) may improve the uteroplacental blood supply and decrease fetal hypoxia and FD.
In a randomized double-blinded clinical trial, a total of 208 low-risk subjects who met our stringent inclusion criteria were randomly assigned into two groups: the Sildenafil citrate group (n=104) and the placebo group (n=104). These participants were referred to our referral gynecology and obstetrics department for delivery between July 2022 to September 2022. The SC group received oral SC at a dose of 50 every 6 , up to a maximum of three times. The final maternal-fetal-neonatal results were recorded and all data were analyzed using SPSS version 23.
The mean age of mothers was 28.98±5.6 years and 120 cases were primigravid (57.7%). Out of a total of 208 pregnant subjects, 168 subjects delivered through normal vaginal delivery (80.8%) and 40 cases underwent emergency CS (19.2%). The number of NVD in Sildenafil group was significantly more than placebo group (87.5% . 74%) and SC decreased the rate of emergency CS to 87.5% (RR=2.46%, 95%CI 1.19-5.08). Also, SC decreased the rate of FD to 53.8% (RR=2.83%, 95%CI of 1-8.24).
The results showed that SC can effectively decrease the rate of emergency CS and FD during labor.
胎儿窘迫(FD)是分娩期间因子宫胎盘血供不足导致紧急剖宫产(CS)的最常见原因之一。有一种理论认为,枸橼酸西地那非(SC)可能改善子宫胎盘血供并减少胎儿缺氧和胎儿窘迫。
在一项随机双盲临床试验中,共有208名符合我们严格纳入标准的低风险受试者被随机分为两组:枸橼酸西地那非组(n = 104)和安慰剂组(n = 104)。这些参与者于2022年7月至2022年9月被转介到我们的妇产科转诊部门进行分娩。SC组每6小时口服50毫克SC,最多服用三次。记录最终的母婴及新生儿结局,并使用SPSS 23版对所有数据进行分析。
母亲的平均年龄为28.98±5.6岁,初产妇120例(57.7%)。在总共208名怀孕受试者中,168名受试者通过正常阴道分娩(80.8%),40例接受了紧急剖宫产(19.2%)。西地那非组正常阴道分娩的数量明显多于安慰剂组(87.5%对74%),SC将紧急剖宫产率降至87.5%(RR = 2.46%,95%CI 1.19 - 5.08)。此外,SC将胎儿窘迫率降至53.8%(RR = 2.83%,95%CI 1 - 8.24)。
结果表明,SC可有效降低分娩期间紧急剖宫产和胎儿窘迫的发生率。
