Factors influencing the postoperative evolution of patients underwent total hip arthroplasty

Abstract

This study aimed to explore the preoperative risk factors related to blood transfusion after hip arthroplasty and the benefits of anterior approach over the traditional lateral approach and to determine the influence of selected factors on the intensity of postoperative pain after hip total hip arthroplasty. Methods: Patients underwent preanesthetic assessment, checking preoperative hemoglobin (Hgb) levels and reassessing on the first and second postoperative days. We also controlled postoperative pain according to our pain control protocol to track opioid need at 6, 12, 24, 48, 96 hours after hip arthroplasty. Results: Risk factors affecting postoperative blood transfusion were highly correlated with preoperative Hgb level. In anterior approach the needed quantities of opioids is lower.
