We retrospectively determined the prevalence and nature of mortality as many as ninety days after 2736 primary and revision total hip arthroplasties performed in 2002 @entity1 by one surgeon at a teaching hospital between January 1969 and December 1996. All but seventy-one of the @entity1 had received prophylaxis against @entity1211 . There were no intraoperative @entity204 , and no events during the operation could be linked directly to postoperative mortality. Eight @entity204 (mortality rate, 0.3 per cent) occurred within ninety days after the 2736 procedures. Four @entity204 (mortality rate, 0.15 per cent) occurred during the initial hospitalization. The cause of seven of the @entity204 was determined. Three @entity1 died as a result of preexisting disease (severe hepatorenal disease, metastatic @entity418 , or severe @entity299 ), and one @entity1 died from sepsis with a gram-negative organism during a thoracotomy eight days postoperatively. A bleeding complication that occurred while the @entity1 was receiving @entity1229 therapy led to the @entity204 of two other @entity1 ; one of these @entity204 occurred in 1974 and the other, in 1982. At the time that these @entity1 were managed, the desired prothrombin time was considered to be twice the control value. The remaining @entity1 , who had had a clip placed on the inferior vena cava after a @entity358 occurred in 1970, died secondary to acute, severe @entity715 of this vessel after a total hip arthroplasty in 1971. The @entity1 for whom the cause of @entity204 was not determined had had an artificial aortic valve and had been receiving chronic @entity1229 therapy. She died suddenly eighty-nine days postoperatively; no autopsy was performed. No @entity1 died as the direct result of a known @entity358 . No @entity204 related to @entity1211 or its prophylaxis or treatment occurred after 1982 (1458 operations). We attribute this, in part, to reduced levels of @entity1229 prophylaxis and improved management with @entity1229 . The ninety-day postoperative mortality rate after 2736 procedures performed over nearly three decades was low (0.3 per cent). This span of time included the period before the introduction of many current improvements in perioperative care, such as routine intubation of @entity1 under general anesthesia, continuous monitoring of the electrocardiogram intraoperatively, and blood-gas determinations. When the @entity1 who died as a result of known, severe preexisting disease were excluded, the mortality rate was 0.18 per cent (five of 2733).
