An intact barrier between the hands of the surgeon and the patient remains the single most important factor in protection against infection for both. Increasing the awareness of possible glove perforation without skin penetration will decrease the risk of contamination.We performed a prospective, randomised trial comparing the incidence of glove perforation using a new type of glove (Regent Biogel Reveal) and standard double-gloves in total hip and knee replacement. One or more perforations was detected in 14.6% of all gloves. The new gloves increased significantly the awareness of perforation. Multiple perforations at the base of the ring finger were found in surgeons who wore wedding rings during the operation and we recommend that rings be removed before undertaking surgery.

Received 6 September 1996; Accepted after revision 4 November 1996Needlestick injuries with perforation of gloves and sometimes skin are common in all surgical specialties with obvious risks of infection. Double gloving, 1,2 the wearing of outer 'orthopaedic' gloves or cloth gloves between two pairs of gloves 3 and the use of a taperpoint needle 4 have reduced the incidence of needlestick injuries. The Regent Biogel Reveal double-gloving system (Regent Hospital Products, Broxbourne, UK) was developed to increase the surgeon's awareness of glove perforation. A special green inner glove turns dark green when punctured with consequent contact with body fluid. The discoloration is clearly visible under the natural-coloured outer glove. Our aim was to investigate the effectiveness of Biogel Reveal gloves during operation for total hip and knee replacement.
PATIENTS AND METHODSPatients undergoing total hip or knee arthroplasty were allocated randomly using sealed envelopes to a 'Reveal' or a 'control' group. The surgeon, first assistant and scrub nurse used the allocated gloves throughout the operation. The outer gloves were changed before the cementing of components and the inner and/or outer gloves if perforation was suspected. All the gloves used during the operation were collected and labelled. Wearers were asked about their awareness of any perforations and blood contamination on the hands. Records were kept of the nature of the operation, the dominant hand, the seniority of the surgeon, first assistant and scrub nurse, and the stage of the operation at which the gloves were changed. The gloves were tested for perforations by filling them with one litre of water and twisting the cuff end of the glove through 360° to increase the pressure. Twenty pairs of unused gloves in both groups were tested for perforations in a similar fashion. We performed statistical analysis using the chi-squared test.
