ABSTRACT
This work presents the procedure applied by our hospital to assess the quality and security of intra operative autotransfusion. The suitability of the three following variables has to be constantly assessed: performance of the machines to concentrate and wash collected blood, bacterial contamination of processed blood and rate of adverse events. We note that the procedure is applied with participation of medical and nursing staff. Since its setting-up, we note an amelioration of suitable variables.

OBJECTIVE: To compare the time course of endotracheal tube cuff pressures in presence of nitrous oxide (N2O), obtained in a tracheal model with those measured during clinical anaesthesia. STUDY DESIGN: Experimental and clinical prospective study. MATERIAL: Twelve brands of low-pressure tracheal tubes. METHODS: The pressure changes in the cuffs were measured over a three-hour-period in presence of a N2O (50 vol%)/O2 (50 vol%) mixture and mechanical ventilation, the tube being inserted either in a tracheal model or in the trachea of patients during general anaesthesia. RESULTS: The results obtained in vitro were correlated with those measured in the patients. Therefore the tracheal model is a helpful guide for the choice of endotracheal tubes.
