New operative technique to reduce surgeons' risk of HIV infection.
The surgical team is potentially at risk of acquiring human immunodeficiency virus (HIV) from the patient. Assuming that the probability of an accidental injury during surgery is 0.01 (P2), the prevalence of HIV is 0.01 (P3) and the seroconversion rate is 0.01 (P1), we have estimated the risk (actuarial model) for a surgeon as 0.2% per year, and 5.82% for 30 years of surgery. In view of this we have made changes in surgical technique to reduce the risk to the surgical team from splash or injury. The surgeon must handle tissue with instruments only and minimize the use of fingers. Whenever possible, sharp instruments should be replaced by a blunt type. The surgical nurse loads needles to the needle carrier using forceps. Sharp instruments are placed in a neutral zone on the nurse's stand so that the surgeon and the nurse never touch the same sharp instrument at the same time. Movements should be controlled, and instrument handling accompanied by eye contact. We consider that these changes will reduce the risk of accidental injuries and thereby the transmission of HIV during operations to a greater degree than knowledge of the patient's HIV status.
