Abstract

Introduction: Joint replacement is associated with massive blood loss. Various techniques have been used to avoid the use of allogeneic blood. One of the techniques used is postoperative salvage and reinfusion of shed blood that was found to reduce the use of banked blood with its potential risk. Materials and methods: We prospectively studied 365 patients who underwent knee joint replacement (TKR) and were divided in two groups. Group A's shed blood (SureTrans System) was collected (n=194) and reinfused and group B's was not (n=171, "controls"). Hemoglobin levels before and after the operation were recorded. Results: Allogeneic blood requirement for TKR decreased by 65% in group A compared to group B. The packed cell/patient index dropped from 0.91 to 0.29 in group 2A. Statistical analysis yielded the odds ratio for blood replacement, a "predicting formula" for blood replacement depending on hemoglobin levels, and a cutoff point for a patient's receiving blood replacement. Conclusion: We recommend using this system in TKR for decreasing allogeneic blood replacement and potential associated risks. The predicting formula for blood replacement may be a helpful tool when making a decision of whether or not to use the collector system and for whom.
