[Surgical gloves--how well do the protect against infections?]

Health care workers (HCW) in surgery are at high risk for bloodborne infections (BBI) e.g. by hepatitis-B(HB)-, hepatitis-C(HC)- and HI-virus. On the other hand, infectious medical staff can cause nosocomial BBI in patients, too. Intact gloves provide an efficient barrier against BBI but glove perforations are common during several surgical procedures. A review of studies on glove perforations during different surgical operations was carried out with special regard to user, number and location of perforations, duration and kind of operation. We compared the results with the frequency of glove perforation during operations in 1938 single used gloves. They were collected after different surgical procedures in a department for general surgery and tested for perforation by 1-liter-water-filling method according to DIN 455/1. The product used during the period of this investigation was Sempermed sterile latex surgical glove. Most perforations were found on the index finger and thumb of the non-dominant hand. Duration of operation, role of the user (primary surgeon) and kind of operation are predictors for the incidence of glove perforations. Double gloving, endoscopic and no-touch techniques decrease the possibility of blood contact during operation. Indicator systems are useful for detection of the loss of glove integrity. Due to the high perforation rate found in this study glove change as a routine during surgical procedures should be discussed (e.g. every 30 minutes).
