Association Between the Frequency of Glove Change and the Risk of Blood and Body Fluid Exposure in Gastrointestinal Surgery.

Abstract

Surgical gloves are used to prevent the transmission of microorganisms from the surgeon's hands to the patient and vice versa. Little is known on the optimal frequency of glove changing. Therefore, we aimed to examine the optimal frequency of glove change during surgery by assessing the glove perforation rate in gastrointestinal surgery. In this observational prospective cohort study, we investigated the incidence of perforation of 5,267 gloves during gastrointestinal surgeries. The overall glove perforation rate was 10.1%. There was no significant difference between single gloving (10.2%) and double gloving (10.0%; p = 0.8491). However, the perforation rate of the inner glove (5.7%) was found to be significantly lower than that of the outer glove (11.6%) (p < 0.0001). A significant difference in perforation rate was observed after wearing inner gloves for 240min (< 240min, 4.4%; ≤ 240min, 7.2%; p = 0.0314), and outer gloves for 60min (< 60min, 7.1%; ≤ 60min, 12.6%; p < 0.0001). We found cumulative perforation rate to rapidly increase until the wear time was 90min. The inner gloves and outer gloves have a higher perforation rate as the wear time increased. To reduce the risk of intraoperative blood and fluid exposure and prevent healthcare-associated infection, gloves should be changed for approximately every 60-90min for outer gloves and approximately every 240min for inner gloves.
