[Isoflurane pollution in operating rooms]. / Inquinamento da isoflurano nelle sale operatorie.

In three operating rooms of a Sardinian hospital, the Authors have measured the air levels of isoflurane using static samplers. Anaesthetic mean daily concentrations ranged from 3.5 to 41.5 ppm in room A, from 4.1 to 24.4 ppm in room B, from 9.5 to 30.4 ppm in room C above all depending on the length and the number of surgical operations. The Authors emphasize the need of suitable prevention measures.
