Pre-operative Routine Cross-match for Elective Total Knee Replacement

Abstract

Total Knee Arthroplasty (TKA) has developed to minimal invasive surgery, decreased blood loss and blood  transfusion, resulted in quick recovery. Nowadays, the routine preoperative crossmatch is still performed for  all patients but not use as a whole. It causes loss of budget and time to prepare blood. This retrospective  descriptive study aimed to find out the proper hemoglobin and hematocrit for crossmatch before TKA in  Buddhachinaraj Phitsanulok hospital from October 2013 to September 2016. The result, there were 366  patients undergone unilateral TKA by the researcher. Pre-operative crossmatch bloods were prepared 380  unit but transfusion only 34 unit. The crossmatch to transfusion ratio was 11.7 and overall transfusion rate  was 8.9. The patients who had pre-operative hemoglobin less than 12 gram/deciliter or hematocrit less than  36% had received blood transfusion 4.5 and 5.7 times more than the patients who had pre-operative hemoglobin more than 12 gram/deciliter or hematocrit more than 36%. In conclusion, the TKA has pre- operative blood preparation more than usages. These results should develop to be guideline for pre-operative crossmatch TKA patients who has pre-operative hemoglobin less than 12 gram/deciliter or hematocrit less than 36%
