Occupational hazards to reproduction and health in anaesthetists and paediatricians.

A mail questionnaire was sent to Finnish anaesthetists and paediatricians to evaluate the risks of reproductive, teratogenic and health complications related to the professions. The incidence of diagnosed spontaneous miscarriages in anaesthetists' families was 10.2% of all pregnancies and it was 13.2% in paediatricians' families. Smoking seemed to increase markedly the incidence of spontaneous miscarriages, which was 22.9% in smoking female anaesthetists and 17.2% in smoking female paediatricians. The gestation times in cases of both full-term pregnancies and miscarriages were shorter in the anaesthetist group than those in the paediatrician group. Congenital abnormalities appeared at an equal rate in both anaesthetist and paediatrician groups, but strikingly, there were nine musculoskeletal abnormalities in the anaesthetists' children compared to no such defects in paediatricians' children. Serious diseases occurred at low frequencies, but three cases of hepatic jaundice and three cases of viral myocarditis in anaesthetists indicate possible infectious hazards to health in anaesthetic work. Different infectious diseases to the respiratory and urinary tracts were commonest among paediatricians. Cancer was not reported in the anaesthetist group. The study does not indicate that gas pollution in operating rooms is harmful to the personnel.
