Three hundred and fifty-eight patients undergoing clean orthopaedic surgery were included in this prospective study. The knives used during surgery, i.e. the knife used for skin incision (the skin-knife) and the knife used to finish the operation were bacteriologically examined. We found no evidence that the practise of discarding the knife after skin incision reduced the incidence of wound infection after clean orthopaedic surgery. Laminar air flow significantly reduced the rate of knife contamination.
本前瞻性研究纳入了358例行骨科清洁手术的患者。对手术中使用的刀具,即皮肤切口用刀(皮肤刀)和手术结束用刀进行了细菌学检查。我们没有发现证据表明在骨科清洁手术后,皮肤切开后丢弃刀具的做法能降低伤口感染的发生率。层流显著降低了刀具污染率。
