The Comparative Study of Epidural and General Anesthesia in Total Hip Replacement

Twenty·six casea of general anesthesia and eighteen cases of epidural anesthesia for total hip replacement which were performed at department of anestheaiolow, Hanrang University Hospital from Jan. 1984 to fun. 1986 were measured blood toss, operation time, volume of whole blood tranafusion and mean arterial blood pressure perioperatively. The result were as follws : 1) Both groups were statistically comparable with regard to sect, height and weight but age of patients were statistically greater in epidural group(p<0.75). The oldest case was 85 years Old in epidural group. 2) The mean operativeblood loss of patients who had their operations under epidural anesthesia was significantly less that that of patients under general anesthesia, being 1,444±769 ml for the epldural group and 2,081±1,051 ml for the general group(p<0.75). 3) The mean bleedin? rate of the patients under epidural anesthesia wart significantly less that of patients under general Anesthesia, being 9.2±3.0 ml/min for th? epidural group and 12.6그5.5 ml/min f7r the general group(P<0.725). 4) The mean volume of whole blood transfusion of patients under epidural anesthesia was significantly less than that of patients under general aneathesia, being 1,178±854 ml for the epidural group and 1,763±73f ml for the general group(7<0.05). 5) There was no case of deep vein thrombosis both groups.
