The purpose of this study was to evaluate the effect of axillary lavage with a gentamicin solution before wound closure on drainage volume. Patients and methods: A prospective, randomized study was performed. Inclusion criteria were a diagnosis of breast neoplasms and plans to undergo an elective axillary lymph node dissection due to axillary metastasis. The patients were randomized into 2 groups: patients undergoing 2 lavages with 500 ml normal saline (Group 1) and patients first undergoing lavage with 500 ml normal saline followed by a second lavage with a 500 ml of a gentamicin (240 mg) solution (Group 2). Microbiological samples were obtained before any lavage, after each lavage and at the time of drain removal. Results: 40 patients were included. Mean number of days maintaining the drain in place was 7.7 +/- 3.2 days in Group 1 and 4.3 +/- 1.4 days in Group 2 (p = 0.001). Total drainage volume before removal was 465 +/- 250.9 ml in Group 1 and 169 +/- 102.2 ml in Group 2 (p = 0.003). After a second lavage with normal saline in Group 1 and after a lavage with gentamicin solution in Group 2, microbiological culture was positive in 10 patients (50%) in Group 1 and 1 case (5%) in Group 2 (p = 0.016). Positive cultures were associated with higher drainage volumes. Conclusion: The postoperative drainage volume of the axillary drain is significantly lower in the patients undergoing a lavage of the surgical bed with a gentamicin solution than in the control group undergoing a lavage with normal saline. A significant reduction in the contamination is only obtained after a lavage with gentamicin solution. Clinical trial registration number: NCT01700504. (C) 2013 Elsevier Ltd. All rights reserved.
