Introduction: There are

different opinions about the relationship between the exposure of pregnant

staff members to anaesthetic gases and the occurance of spontaneous abortion. 

Objective: The purpose of this study was to determine the relationship between

the exposure to anaesthetic gases and the occurance of spontaneous abortion. 

Design and Methods: This is a case control study performed at all educational

hospitals of tehran. All staff personnel were interviewed and then were

devided to case and control group according to the ward they were working

during their pregnancy. Case group spent their pregnancy in operating rooms.

The control group were working in other wards of hospital except operating

room, angiography, radiotherapy, radiology, chemicotherapy and x-ray units.

687 hospital staff members were matched in charectristics such as age of

pregnancy occurred, number of deliveries, and the number of cigarettes smoked

per day. 

Results: Out of 524 pregnanc cases, 262 were exposed to anaesthetic

gases during pregnancy. The rate of spontaneous abortion was 9.06% (case group),

and 5.97% in the control group.The difference was not statistically

significant (p>0.05). That means there is no relationship between the

occupational exposure to anaesthetic gases and spontaneous abortion. 

Conclusion: Occupational hazerds always exist and avoidance of unreasonable

exposure is rational.therfore medicall staph shoud receive warrents in this

regard.
