Donning Gloves Before Surgical Gown Cross-contaminates the Assistant

Abstract

Background: Maintaining a sterile surgical environment is of the upmost importance in total joint arthroplasty. The surgical gown-glove interface is a frequent and known cause of bacterial contamination. A variation of the traditional staff-assisted open-gloving technique has been developed in an attempt to address this. In this method, the surgeon dons their undergloves before their gown. Although this has demonstrated improved sterility for the surgeon, no studies have considered the effects of this technique on the person assisting the surgeon. The present study was designed to investigate this. We hypothesize that the process of donning undergloves before the surgical gown leads to higher rates of contamination for the assistant. Methods: We performed a comparative study between the traditional and a gloves-first scrubbing technique. We assessed the differences in gown and glove contamination of the surgical assistant following each scrubbing event. Two surgeons applied ultraviolet light-disclosing lotion to their upper extremities and then performed each method in a randomized order with 40 surgical technologists/nurses. Blinded evaluators then quantified the amount of contamination on the surgical assistant's gown and gloves. Results: The gloves-first technique resulted in increased contamination of the surgical assistant's gloves (P = .002). There was no difference in contamination of the surgical gown (P =.982). Conclusions: Although the staff-assisted open-gloving technique may improve the sterility of the surgeon, it does so at the expense of the surgical assistant. Surgeons adopting this technique should consider donning their own undergloves or having the assistant rescrub before any further contact with the sterile environment.
