Eighty-five consecutive patients were randomized to undergo mass closure of the abdomen with no. 1 polydioxanone mounted on either a blunt-tipped (n = 46) or cutting (n = 39) needle. Gloves were changed before closure and tested for perforation afterwards using standard air or water techniques. Fourteen pairs of gloves were punctured when using a cutting needle, and three pairs when a blunt-tipped needle was used. The majority of punctures were to the non-dominant glove. The surgeon was aware of the puncture in eight of the 14 instances involving a sharp needle and in one of the three involving a blunt-tipped needle. Blunt-tipped needles, while not eliminating the risk, significantly reduced the incidence of surgical glove puncture (P < 0.001, Fisher's exact test). The use of cutting needles for abdominal closure should be abandoned.
85例连续患者被随机分为两组，分别使用安装有1号聚二氧六环酮缝线的钝头针（n = 46）或切割针（n = 39）进行腹部大面积缝合。缝合前更换手套，缝合后使用标准的空气或水检测技术检测手套是否穿孔。使用切割针时，有14对手套被刺破；使用钝头针时，有3对手套被刺破。大多数穿孔发生在非优势手的手套上。在14例使用锐针的情况中，有8例外科医生意识到手套被刺破；在3例使用钝头针的情况中，有1例外科医生意识到手套被刺破。钝头针虽然不能消除风险，但显著降低了手术手套穿孔的发生率（P < 0.001，Fisher精确检验）。应摒弃使用切割针进行腹部缝合的做法。
