title: Wound drainage versus non-drainage for proximal femoral fractures. A prospective randomised study.
abstract: OBJECTIVE
  The purpose of this prospective randomised study was to examine whether routine drainage in surgery for traumatic hip fractures is useful.
  
  
  METHODS
  At the end of surgery for hip fractures, 200 consecutive patients (51 men, 149 women) were randomised to receive suction drainage or not. The status of wound healing was evaluated, with specific reference to haematoma formation or wound infection. Indices of blood loss were the average blood loss during operation, a decrease in the haemoglobin level, fluid collected by the drain, and blood transfusion.
  
  
  RESULTS
  The severity of wound haematoma and the number of wound infections was not significantly different between the two groups. The average blood loss during operation was 172 ml in the drainage group and 179 ml in the non-drainage group. The volume of drainage fluid was 146 ml. The haemoglobin concentration decreased by 1.4 mg/dl in the drainage group and by 1.3 mg/dl in the non-drainage group (P = 0.83). During admission, 55 patients in the drainage group received 2.5 units of blood and 50 patients in the non-drainage group received 2.7 units.
  
  
  CONCLUSIONS
  The severity of wound haematoma does not lead to statistically significant differences in wound infection rate. The routine use of suction drains may not prevent wound infections.
