A secure blood-saving protocol for Jehovah’s Witnesses in primary total hip replacement

Abstract

Objectives: The study aimed to analyze the efficacy of the blood management protocol developed by our team for patients who are Jehovah’s Witnesses (JW) presenting for primary total hip replacement (THR). Patients and methods: Thirty JW patients (6 males, 24 females; mean age: 70.1±9.8 years; range, 65 to 81 years) and 30 age- and sex-matched controls (6 males, 24 females; mean age: 68.7±9.1 years; range, 62 to 79 years) who underwent primary THR at our institution between January 2018 and June 2020 were retrospectively evaluated. While the surgical technique of THR was not different among the groups, blood loss management differed between the groups. Patients in the control group were given 1 g of intravenous tranexamic acid (TXA) 15 min before the surgical incision. In addition to the same TXA protocol, intraoperative cell salvage with a continuous autologous transfusion system was used for JW patients. The estimated blood loss (EBL) was determined using Meunier's formula. Hemoglobin (Hgb) decline, EBL on the first and third postoperative days, allogenic blood transfusion (ABT) requirement, and complications were analyzed between groups. Results: There were no significant differences between groups regarding demographic and clinical characteristics (p>0.05), ABT requirement (p>0.999), and Hgb decline in the first and third postoperative days (p=0.540 and p=0.836, respectively). Furthermore, both groups did not significantly differ between EBL in the first and third postoperative days (p=0.396 and p=0.616, respectively) and the length of hospital stay (p=0.547). Similar complication rates were noted for both groups. Hemoglobin level assessments revealed that values on the first and third postoperative days were significantly lower than the baseline Hgb value in both cohorts (p<0.001). Conclusion: A combination of intravenous administration of 1 g of TXA, meticulous hemostasis, and intraoperative use of cell saver constitutes a reasonable strategy for achieving the goal of transfusion-free primary THR with predictable levels of blood loss that are similar to non-JW patients.
