The efficacy of perioperative antibiotic therapy on recovery following tonsillectomy in adults: randomized double-blind placebo-controlled trial.

One hundred and one adult patients undergoing tonsillectomy for chronic/recurrent tonsillitis completed a prospective, randomized, double-blind, placebo-controlled study in which ticarcillin disodium and clavulanate potassium (Timentin) or placebo was administered intravenously at the time of surgery and for 12 hours postoperatively. The patients than received oral amoxicillin and clavulanate potassium (Augmentin) therapy or placebo for an additional seven days. Each patient kept a daily log to assess the incidence and severity of postoperative symptoms. Tonsillar core tissue at the time of surgery, as well as tonsillar fossa cultures after 7 days of treatment, were obtained. Those patients who received antibiotics fared consistently better in the immediate postoperative period compared with the placebo group. Specifically, patients in the antibiotic group experienced significantly less mouth odor, were able to tolerate a regular diet sooner, and resumed their normal activities earlier than did patients who received placebo. Patients who received antibiotics experienced fewer days with mouth odor (p = 0.004). In addition, on postoperative days 3 to 5, the antibiotic group was eating a regular diet (p = 0.05) and had returned to their routine activities earlier (p = 0.045) when compared with the placebo group. Perioperative antibiotic therapy was well tolerated and was effective in minimizing symptoms after tonsillectomy.
