Abstract:
Objective To study the correlated mechanisms and clinical effect of hidden hemorrhage after total hip arthroplasty (THA) and total knee arthroplasty(TKA). Methods From March 2001 to May 2005, 61 patients were treated with THA and 73 patients were treated with TKA. The patients treated with THA involved 22 males and 39 females with an average age of 68 years(range 61-79 years). The patients treated with TKA involved 23 males and 50 females with an average age of 73 years(range 65-77 years). All arthroplasties were primary and unilateral, and the 24 h fluid resuscitation was not more than 2000 ml. Using Gross formula, the true total blood loss was calculated depending on height, weight and pre- and post-operation Hct, and the hidden hemorrhage was got by subtracting the visible blood loss from total loss. Results Following THA, the mean total loss was 1520 ml and the hidden hemorrhage 482 ml(32%). Following TKA, the mean total loss was 1508 ml and the hidden hemorrhage was 776 ml(52%). The difference of hidden hemorrhage between THA and TKA was significan different(P
