This prospective observation sought to determine if scalpel blades used for abdominal skin incisions in dogs are a significant source of bacterial contamination, and if these blades should be changed prior to use in deeper dissection.
Scalpel blades were swabbed for culture prior to skin incision as a control, and then again following ventral midline abdominal skin incision in a total of 75 dogs. Culture and sensitivity results were compared with review of medical records for any evidence of pre- or postoperative incisional surgical site infection/inflammation (SSI). Of the 75 blades swabbed after skin incision, only 2 (2.7%) had positive culture results. Of the 69 patients that survived to suture removal, there was evidence of SSI in 6 patients (8.7%), only one of which had a positive scalpel blade culture (16.7%). Neither the use of postoperative antibiotics nor positive scalpel blade culture results were good predictors of whether a patient would develop a SSI. Results of this pilot study suggest that there is no bacteriological evidence to support the use of a separate blade for deep dissection in routine surgical procedures.
本前瞻性观察旨在确定用于犬腹部皮肤切口的手术刀刀片是否为细菌污染的重要来源，以及在进行更深层次解剖前是否应更换这些刀片。
在总共75只犬中，在皮肤切口前对手术刀刀片进行拭子培养作为对照，然后在腹中线腹部皮肤切口后再次进行培养。将培养和药敏结果与病历进行回顾，以查找术前或术后手术部位感染/炎症（SSI）的任何证据。在皮肤切口后拭子取样的75把刀片中，只有2把（2.7%）培养结果呈阳性。在存活至拆线的69例患者中，有6例（8.7%）有SSI证据，其中只有1例手术刀刀片培养呈阳性（16.7%）。术后使用抗生素和手术刀刀片培养阳性结果均不能很好地预测患者是否会发生SSI。这项初步研究的结果表明，没有细菌学证据支持在常规手术中使用单独的刀片进行深层解剖。
