Women frequently suffer perineal trauma while giving birth. Interventions to increase the possibility for an intact perineum are needed.
To evaluate the effectiveness of antenatal perineal massage in increasing the likelihood of delivering with an intact perineum.
This single blinded prospective controlled trial included 234 nulliparous women with a singleton fetus. Women allocated to the study group were instructed to practice a 10 minute perineal massage daily from the 34th week of gestation until delivery. Primary outcome measures included the episiotomy rate; first, second, third and fourth-degree perineal tear rates; and intact perineum. Secondary outcomes were related to specific tear locations and the amount of suture material required for repair.
Episiotomy rates, overall spontaneous tears and intact perineum rates were similar in the study and control groups. Women in the massage group had slightly lower rates of first-degree tears (73.3% vs. 78.9%, P = 0.39) and slightly higher rates of second-degree tears (26.7% vs. 19.3%, P= 0.39), although both of these outcomes did not reach statistical significance. The rates of anterior perineal tears were significantly higher in the massage group (9.5% vs. 3%, P = 0.05), whereas internal lateral tears rates were slightly lower but without statistical significance (11.5% vs.13.1%, P=0.44).
The practice of antenatal perineal massage showed neither a protective nor a detrimental significant effect on the occurrence of perineal trauma.
女性分娩时经常会遭受会阴创伤。需要采取干预措施以增加会阴完整的可能性。
评估产前会阴按摩在提高会阴完整分娩可能性方面的有效性。
这项单盲前瞻性对照试验纳入了234名单胎初产妇。分配到研究组的女性被指导从妊娠第34周开始每天进行10分钟的会阴按摩,直至分娩。主要结局指标包括会阴切开率;一、二、三、四度会阴撕裂率;以及会阴完整情况。次要结局与特定的撕裂部位和修复所需的缝合材料量有关。
研究组和对照组的会阴切开率、总体自然撕裂率和会阴完整率相似。按摩组一度撕裂率略低(73.3%对78.9%,P = 0.39),二度撕裂率略高(26.7%对19.3%,P = 0.39),尽管这两个结局均未达到统计学显著性。按摩组会阴前部撕裂率显著更高(9.5%对3%,P = 0.05),而会阴内侧撕裂率略低但无统计学显著性(11.5%对13.1%,P = 0.44)。
产前会阴按摩对会阴创伤的发生既没有显著的保护作用也没有显著的有害作用。
