Randomized Controlled Trial Comparative Study Clinical TrialA prospective randomized trial of single versus multiple drains in the axilla after lymphadenectomy.
Increasing duration and amount of postoperative fluid formation after axillary lymphadenectomy delays final healing. We postulated that multiple drains (instead of a single drain) might decrease postoperative fluid accumulation by their greater proximity to points of leakage. We randomized 65 women with clinical stage I or II carcinoma of the breast to single or multiple drains. ⋯ The two arms (single versus multiple drains) were determined to be homogeneous in other variables that may affect postoperative fluid formation--age, size of the breast, weight, height, obesity, presence of previous surgical biopsy, excision of pectoralis minor muscle, excision of thoracodorsal complex, level of axillary dissection, number of lymph nodes, number and proportion of positive lymph nodes and whether or not the dominant hand was on the side operated upon. Single versus multiple drains had no clinically significant effect on the amount or duration of drainage, as an inpatient or outpatient, or total. We recommend a single drain to the axilla after lymphadenectomy.
