The aim of this study was to evaluate the role of blunt suture needles for episiotomy repair at uncomplicated vaginal deliveries in reducing glove perforation rate.
This was a prospective randomized controlled trial wherein 300 nulliparous women with uncomplicated vaginal deliveries were randomized to episiotomy repair with either blunt or sharp suture needles. Patient demographics and clinical variables were collected. Postoperatively, the surgeons were surveyed regarding ease of using the needle, and glove perforation was determined by three tests: air insufflation, water filling and water load.
A total of 41 perforations occurred in the 39 episiotomy repairs with glove perforations (13%). There was a significantly higher number of glove perforations using the sharp suture needles (28/150; 18.7%) than with the blunt suture needles (11/150; 7.3%) (P = 0.005). Glove perforation of the non-dominant hand occurred in 90% of the cases. Using a blunt suture needle took significantly more time (P < 0.001) to complete the repair than using a sharp needle. Surgeons reported that blunt needles were more difficult to use than sharp needles (P < 0.001).
Blunt suture needles for episiotomy repair were shown to have a significantly lower instance of glove perforation but required more time and are perceived to be more difficult to complete the repair as compared to sharp needles.
本研究旨在评估钝头缝合针在无并发症阴道分娩时会阴切开术修复中对降低手套穿孔率的作用。
这是一项前瞻性随机对照试验,300例无并发症阴道分娩的初产妇被随机分为使用钝头或尖头缝合针进行会阴切开术修复。收集患者人口统计学和临床变量。术后,对外科医生就使用针的难易程度进行调查,并通过三种测试确定手套穿孔情况:充气、注水和水负荷试验。
在39例会阴切开术修复中有手套穿孔的病例中共发生41次穿孔(13%)。使用尖头缝合针的手套穿孔数量(28/150;18.7%)显著高于钝头缝合针(11/150;7.3%)(P = 0.005)。90%的病例非优势手发生手套穿孔。使用钝头缝合针完成修复比使用尖头缝合针花费的时间显著更多(P < 0.001)。外科医生报告钝头针比尖头针更难使用(P < 0.001)。
与尖头针相比,用于会阴切开术修复的钝头缝合针显示手套穿孔发生率显著更低,但需要更多时间,且被认为更难完成修复。
