Goal Of The StudyTo determine over a whole country what are the factors associated with an intraoperative homologous blood transfusion and with the use of autologous techniques (preoperative autologous blood donation: PABD; acute normovolemic hemodilution: ANVH; intraoperative red cell salvage: IRCS).Study DesignNational enquiry using a large representative sample (3 days of anaesthesia in France).MethodsUnivariate followed by multivariate analyses of data gathered in 1996 during the survey leaded by the French society of anaesthesia and intensive care (Sfar) and corresponding to 884 scheduled hip and knee prosthesis surgical procedures.ResultsFactors associated with a decreased use of PABD programme were: 1--old age and high ASA physical status; 2--procedures of short duration. By contrast, an increased use of PABD was associated with anaesthetics in which a closed circuit had been used. Except for a significant association with increasing age and with absence of PABD used, no additional factor was found to be linked with ANVH. No factor among those studied was found related to the use of IRCS. Homologous blood transfusion was more frequently used in ASA > or = 3 patients, in long duration surgeries while its use was decreased in patients with PABD (odds ratio--for reduction by PABD: 4.4 [95% confidence interval: 2.2-8.8]). Homologous blood transfusion was not related to the use of ANVH or IRCS.ConclusionThese data obtained from a large national survey confirm previously published studies and meta-analyses and are in agreement with current recommendations. An unexpected relation between PABD and closed circuit anaesthesia has been found.
