The prevalence of latex allergy in operating theatre staff

Abstract

Latex allergy has become increasingly common amongst health care workers. The prevalence of latex allergy in 102 theatre personnel at Princess Alexandra Hospital was determined by the results of a standardized questionnaire and a latex specific IgE radioallergosorbent test (RAST). Volunteers had their forced expiratory volume in 1 second/forced vital capacity (FEV1/FVC) measured at the beginning and end of their working shifts. Only one of 102 volunteers had a positive latex specific IgE RAST and he also experienced both local and systemic symptoms with latex exposure and a deterioration in daily FEV1/FVC. The 14 volunteers using asthma medications had significantly higher incidence of operating theatre symptoms (10/14), local reactions (8/14), and atopy (14/14). There was no clinically significant daily change in FEV1 in the total population or any specific group. The 1% (1/102) prevalence of latex allergy and sensitization in theatre staff demonstrates a much lower incidence than previously reported (12.5%1, 15.8%2).
