Abstract
BackgroundDrainage is a routine practice used to reduce hematoma and blood loss following total hip arthroplasty. The aim of this study was to assess the effect of clamped drainage on blood loss and wound healing after total hip arthroplasty.MethodsA prospective cohort of 44 patients with hip osteoarthritis or femur head necrosis undergoing total hip arthroplasty was randomized equally into two groups: 6-h postoperative clamped or non-clamped suction tube drainage. Body mass index, gender distribution, preoperative hemoglobin, hip pathology, and affected side were comparable between the two groups. Blood loss, hemoglobin levels, and wound healing complications were recorded and compared between groups.ResultsThe drainage blood loss and calculated blood loss volumes were higher for the non-clamped group. About 100 mL more blood loss was noticed in the non-clamped group. There was no significant difference in adverse events or need for transfusion.ConclusionsThe present study showed a statistically significant reduction in postoperative drainage amount between clamped and unclamped drainage groups, but this difference was not large enough to warrant increased blood transfusion requirements in patients with unclamped drainage. Further studies are essential to define the critical period of clamping that is compatible with the dual objectives of reduced blood loss and lack of wound complications from hematoma.
Highlights
Total hip arthroplasty (THA) is a successful and widely used method to treat hip disorders such as hip osteoarthritis (OA) and femoral head necrosis.THA can relieve pain, correct deformity, and restore and improve joint movement, making it widely performed by surgeons and accepted by patients
Hematomas are inevitable to a certain extent as complete hemostasis is difficult when the medullary canal is exposed, increasing wound tension, decreasing tissue perfusion, resulting in anemia, and providing an ideal medium for bacterial culture, all of which work against wound healing
This study was performed in order to establish if postoperative clamping had an effect on blood loss, postoperative complications, and Hb levels after cementless THA
Summary
Total hip arthroplasty (THA) is a successful and widely used method to treat hip disorders such as hip osteoarthritis (OA) and femoral head necrosis.THA can relieve pain, correct deformity, and restore and improve joint movement, making it widely performed by surgeons and accepted by patients. Due to the extensive soft tissue and bone dissection, patients undergoing THA are prone to between 1000 and 2000 mL of blood loss [1,2,3]. It has been reported that clamping drainage can reduce blood loss and the need for blood transfusion after total knee arthroplasty (TKA) [13]. No similar reports concerning the application of clamping drainage in THA could be found. This study was conducted to clarify whether clamping drainage for 6 h postoperatively can contribute positively to the postoperative management of cementless THA, by reducing blood loss and minimizing postoperative wound complications. Drainage is a routine practice used to reduce hematoma and blood loss following total hip arthroplasty. The aim of this study was to assess the effect of clamped drainage on blood loss and wound healing after total hip arthroplasty
