Drainage versus nondrainage in simultaneous bilateral total hip arthroplasties

Abstract

A prospective study of 48 patients (96 hips) who had undergone primary simultaneous bilateral total hip arthroplasty was conducted to assess the effect of postoperative suction drainage on wound healing and infection. A suction drain was placed by randomization of the drained versus undrained side. The same surgical technique was used in all total hip arthroplasty wounds. Statistical analysis of the results showed significant differences with respect to drainage from the wound, soaked dressings requiring reinforcements, ecchymosis, and erythema about the wound in the group without drainage. There was no specific correlation between the incidence of wound complications and infection after total hip arthroplasty and the use or nonuse of closed-suction drainage. The hip score and range of motion of the hip were unaffected by the use or nonuse of the drains. The cost of 1 set of hemovac drains is $135 and the cost for 4-5 dressings and bed sheet changes is about $50. Although the hemovac is more expensive, the authors recommend the routine use of suction drains for wounds after primary total hip arthroplasty to reduce drainage, soaked dressings requiring reinforcement, ecchymosis and erythema around the wound, and psychological impact on the patient's fear of bleeding.
