Background
Microbiological contamination of surgical gloves occurs during surgery, which may warrant glove change during orthopaedic surgeries. However, no systematic review of this topic has previously been published. Therefore, this review evaluated whether changing gloves during arthroplasty surgeries reduces the risk of surgical site infection/prosthetic joint infection (SSI/PJI) and the optimal frequency of glove change.
Methods
Search terms such as surgical gloves, surgical site infections, prosthesis‐related infections, arthroplasty were used, including Medical Subject Headings terms. Of the 89 articles screened, 12 articles were included for qualitative synthesis.
Results
No studies measured the direct effect of glove change on PJI rate. Therefore, microbiological contamination and perforation rate of gloves were used as surrogate outcomes. Eight studies evaluated microbiological contamination of surgical gloves, with rates ranging from 3.4 to 30%. Five contamination studies recommended changing gloves after draping and before handling implants. One randomized controlled trial also recommended changing gloves at least once an hour regardless of surgical stages. Five studies recommended changing gloves to prevent perforation, with recommendations ranging from 20 to 90 min. Furthermore, one study advised change of gloves after resection of bone and before implantation.
Conclusion
As microbiological contamination rates of gloves increase with duration of surgery, glove changes are recommended at least once per hour. Furthermore, gloves should be changed after draping, before handling implants and if visible perforation is seen to reduce contamination. Due to the lack of studies with SSI/PJI as primary outcomes, we cannot draw a definitive conclusion regarding the effectiveness of changing gloves in reducing the risk of SSI/PJI in arthroplasty.
