title: [HEMOSTASIS EFFECT OF COMPRESSION DRESSING THERAPY AFTER TOTAL HIP ARTHROPLASTY].
abstract: OBJECTIVE
  To investigate the hemostasis effect of compression dressing therapy after total hip arthroplasty (THA).
  
  
  METHODS
  Thirty-four patients undergding unilateral THA between December 2014 and March 2015 were randomly divided into observation group (compression dressing group, n = 17) and control group (ordinary dressing group, n = 17). There was no significant difference in gender, age, height, weight, lesion hips, pathogeny, disease duration, and preoperative hemoglobin between 2 groups (P > 0.05). The total blood loss theoretical value, the postoperative drainage volume, the visible blood loss, the hidden blood loss, the total blood transfusion volume, the number of patients receiving blood transfusion, and the related complications were compared between 2 groups.
  
  
  RESULTS
  No significant difference was found in operation time and hospitalization time between 2 groups (t = 0.337, P = 0.738; t = 0.140, P = 0.889). The incisions healed by first intention in all patients. Six cases had incision subcutaneous hematoma in the control group, no incision subcutaneous hematoma occurred in the observation group (χ² = 7.286, P = 0.018). No postoperative complications of wound superficial infection and venous thrombosis occurred in 2 groups. After operation, blood transfusion was given in 1 case of observation group and 7 cases of control group, showing significant difference (χ² = 5.885, P = 0.039), and the total blood transfusion volume was 600 mL and 3 200 mL, respectively. There was no significant difference in preoperative blood volume and intraoperative blood loss between 2 groups (P>0.05), but the total blood loss theoretical value, the postoperative drainage volume, the visible blood loss, and the hidden blood loss in observation group were significantly less than those in control group (P < 0.05).
  
  
  CONCLUSIONS
  The compression dressing should be performed after THA because it can effectively reduce postoperative blood loss and the incidence of wound hematoma.
