Effect of perioperative treatment with ambroxol on lung cancer patients after video-assisted thoracic surgery lobectomy

To evaluate the influence of perioperative intravenous administration of ambroxol on pulmonary function, postoperative complications, postoperative hospital stay, and cost after video-assisted thoracic surgery lobectomy for lung cancer. Sixty patients who underwent video-assisted thoracic surgery lobectomy for lung cancer in Xiangya Hospital, Central South University between May 2011 and May 2012 were randomly assigned into 2 groups: An ambroxol group (n=30) and a control group (n=30). In the ambroxol group, patients were given ambroxol (1 000 mg/d) on the day of operation and on the first 3 postoperative days. In control group, placebo was given. The pulmonary function tests, arterial blood gases, incidence of perioperative morbidity, postoperative mechanical ventilation time, duration of ICU stay, length and costs of postoperative hospital stay were compared between the 2 groups. The 2 groups were well matched for demographics and operative variables. The ambroxol group showed better the percent predicted f
