Drainage in breast reduction surgery: a prospective randomised intra-patient trail. Wound drains in proximal femoral fracture surgery: a randomized prospective trial of 177 patients. Draining after breast reduction: a randomised controlled inter-patient study.
One hundred and fifty bilateral breast reductions were prospectively randomised intra-operatively to receive a unilateral wound drain. Seven patients required post-operative evacuation of haematoma, three on the drained and four on the undrained sides. There was no statistical difference in haematoma formation between drained and undrained sides (p = 1), or the incidence of wound healing or other complications. We believe that routine wound drainage in breast reduction surgery is an unnecessary intervention. We report on a prospective randomized trial on the effect of wound drains on wound healing following surgery for proximal femoral fractures. One hundred and seventy-seven consecutive patients admitted to Queen's Medical Centre Nottingham, undergoing AO dynamic hip screw (DHS) or hemiarthroplasty were randomized whether or not to receive wound drainage. Wound healing was assessed in terms of ultrasound examination, the ASEPSIS wound score system and overt infection rates. All patients were followed up at 6 weeks and 6 months. Ultrasound examinations showed that drains were indeed ineffective in preventing haematoma formation, the first time this has been demonstrated objectively. However, using drains failed to prevent late seroma formation. Patients who received wound drainage showed statistically better wound healing on the ASEPSIS wound scoring system and a reduced infection rate. The ASEPSIS scores on day 2 and 5 postoperatively proved an accurate predictor of poor wound healing. This study conflicts with previous smaller studies which failed to show an effect of wound drainage upon wound healing, and strongly supports the use of wound drains. One hundred and seven bilateral breast reductions were prospectively randomised during surgery to receive or not receive wound drains. Fifty-five patients were randomised to have a drain and 52 to not have a drain. There was no statistical difference in the number of complications between the drained and undrained group (P=0.092; student's t-test for independent observations). Twenty-two of the 55 patients in the drained group had a complication, 12 of the 52 patients in the undrained group had a complication. The hospital stay was significantly shorter (P<0.001) in the undrained group. The main discomfort score due to the presence of the drains was 5.62, which can be qualified as high. This study demonstrates that breast reduction without postoperative draining does not increase the risk of complications, increases the patient's comfort and significantly reduces hospital stay.
The limited evidence available shows no significant benefit of using post-operative wound drains in reduction mammoplasty, though hospital stay may be shorter when drains are not used. No data are available for breast augmentation or breast reconstruction, and this requires investigation.
