Postoperative Noninvasive Hemoglobin Monitoring Is Useful to Prevent Unnoticed Postoperative Anemia and Inappropriate Blood Transfusion in Patients Undergoing Total Hip or Knee Arthroplasty: A Randomized Controlled Trial

Abstract: Introduction Postoperative nadir hemoglobin (Hb) is related to a longer length of stay for geriatric patients undergoing orthopedic surgery. We investigated whether postoperative pulse Hb (SpHb) measurement is useful for avoiding anemia and inappropriate blood transfusion after total hip arthroplasty and total knee arthroplasty. Material and Methods This prospective randomized controlled study included 150 patients randomly assigned to receive blood transfusion, either guided by SpHb monitoring (SpHb group) or… Show more

“…In a clinical setting, changes in Hb concentration can also be an indicator of alterations in the oxygen supply in peripheral tissues. Moreover, during surgical procedures or in intensive care units, Hb concentrations can serve as a guide for deciding on when to perform blood transfusions, showing the importance of Hb monitoring during the anesthetic–surgical period [ 10 , 11 , 12 ].…”
