Beneficial effects on intraoperative and postoperative XXXX in total hip replacement when performed under lumbar epidural anesthesia. An explanatory study.

@entity1 @entity190 @entity6305 @entity551 @entity3575
The effects of continuous lumbar epidural anesthesia and two types of general anesthesia on @entity190 and hemodynamics during and after total hip replacement were compared in three groups of @entity1 . Fourteen @entity1 received local anesthetics via continuous lumbar epidural administration; 10 @entity1 received inhalational anesthetics and breathed spontaneously after endotracheal intubation; and 14 received artificial ventilation after intubation and intermittent intravenous (i.v.) injections of @entity6305 and @entity3575 . The results documented that both intraoperative and postoperative blood losses were significantly reduced in @entity1 subjected to total hip replacement under lumbar epidural anesthesia as compared with the @entity1 receiving the two general anesthetic techniques. Hemodynamic differences explained the differences in @entity190 . The epidural anesthesia induced @entity551 on the arterial and venous sides as compared with the two general anesthetic techniques. Inhalational anesthesia also induced @entity551 on the arterial and venous sides intraoperatively as compared with general anesthesia with artificial ventilation. Postoperatively, the hemodynamics of the general anesthesia groups were similar, and no differences in @entity190 occurred. Continuous' epidural anesthesia can be viewed as a tool to achieve @entity551 anesthesia--notably on the venous side--for the purpose of minimizing @entity190 . The reduction in @entity190 associated with lumbar epidural anesthesia is beneficial in decreasing the hazard and cost of blood transfusion.
