[Tourniquet pain: anatomic-physiological notes and clinical aspects].
OBJECTIVES: The mechanism of tourniquet pain is quite complex. This paper, supported by the previous literature on this topic, tries to explain why the anaesthetic blockade of a limb, even when thechnically successful, not always prevents the occurrence of this pain. DATA SOURCES: Papers published between 1990 and 1995, listed on Index Medicus, with pertinent references. STUDY SELECTION: Reports dealing with physiological basis of tourniquet pain. CONCLUSIONS: Tourniquet pain is nociceptive, generated not only by activation of peripheral nociceptors, but also by direct axonal stimulation of nervous trunks. Is is hardly to tolerated by patients since ischemia and mechanical compression induce an activation of C fibres, resistent to ischemia. A beta fibres are involved as well, due to the activation of low-threshold mechanoceptors.

[Qualitative characteristics of human exposure to air chemical pollutants in operating rooms].
UNLABELLED: For more than two decades many studies have been published searching for a link between exposure to volatile anaesthetic agents and health damage even if it is noteworthy that many other chemical substances can be found in the Operating Room. Purpose of this study was to demonstrate that the Operating Room is not a totally confined environment and that it is possible to perform an, at least qualitative, evaluation of many different polluting contaminants, even unexpected, to whom the working staff is exposed. MATERIAL AND METHODS: The study has been performed in the Operating Rooms of the Departments of Urology and Orthopaedics. Two methods have been employed: a long-casting sampling of volumes of air (with a sampling device composed of an enrichment system and a low flow aspirating pump) and an anaesthetic vapours and gas continuous analyzer. Results. We never recorded environmental levels of anesthetic higher than the currently accepted ones. Many other organic compounds of different kind have been found (irritants, cancer-organs). Their presence, not desirable in a place where a demanding work is performed, deserve further investigation and a quantitative evaluation of these compounds.
