A randomized prospective study was undertaken to determine the rate of punctures of the inner glove when techniques of double-gloving were employed for orthopaedic operations. Group I consisted of twenty-five procedures in which double latex gloves were used, and Group II comprised another twenty-five in which latex inner gloves and cloth outer gloves were worn. As the outer glove was expected to act as a barrier against puncture of the inner glove, only inner gloves were tested. All glove exchanges done intraoperatively for presumed tears of the inner glove were noted, as were punctures of the skin. The type and length of the procedure were also documented. Group I (double latex gloves) had a significantly higher rate of total inner-glove perforations per procedure (p less than 0.0001) than Group II (cloth and latex gloves). Furthermore, unrecognized perforations were significantly higher in Group I than in Group II (p less than 0.01). In Group I, the number of punctures increased with the duration of the operation; a puncture was found in all procedures in which the operation lasted longer than three hours (p less than 0.01). In Group II, only two tears of the inner glove occurred. Both were unrecognized and were independent of the duration of the operation.
开展了一项随机前瞻性研究，以确定在骨科手术中采用双层手套技术时内层手套的穿刺率。第一组包括25例使用双层乳胶手套的手术，第二组包括另外25例佩戴乳胶内层手套和布质外层手套的手术。由于预计外层手套可作为内层手套防穿刺的屏障，因此仅对内层手套进行测试。记录了术中因推测内层手套撕裂而进行的所有手套更换情况，以及皮肤穿刺情况。还记录了手术类型和时长。第一组（双层乳胶手套）每例手术内层手套总穿孔率显著高于第二组（布质和乳胶手套）（p<0.0001）。此外，第一组未被识别的穿孔显著高于第二组（p<0.01）。在第一组中，穿刺次数随手术时长增加；在所有持续时间超过三小时的手术中均发现有穿刺（p<0.01）。在第二组中，仅发生了两例内层手套撕裂。均未被识别，且与手术时长无关。
