[Comparison of double-lumen endobnonchial versus single-lumen endotracheal tube anesthesia in bilateral thoracoscopic sympathectomy].

Since the development of video endoscopic surgery, the number of transthoracic endoscopic sympathectomy has been increasing. The use of double-lumen endobronchial tube or single-lumen endobronchial tube during anesthesia for these surgeries has been a controversial. 385 palmar hyperhidrosis patients divided into three groups: group I, under alterative one lung ventilation anesthesia with double-lumen endobronchial tube; group II, under alterative one lung ventilation anesthesia with single-lumen endobronchial tube; group III, under two lung ventilation anesthesia with single-lumen endobronchial tube were studied. All had received bilateral thoracoscopic sympathectomy. The age of patients ranged from 8 to 64 years old. There were 154 male and 231 female. The average anesthesia durations for group I, II and III were 38.56 +/- 10.28, 34.14 +/- 5.21, 31.83 +/- 3.34 min respectively. The variables considered in the study were: physique of the patients; duration of anesthesia; airway pressure changes; SaO2 changes during the operation and post-anesthesia complaints. We found that upon using double-lumen endobronchial tube, SaO2 levels was better maintained especially in the obese patients and the patients who had received a traditional surgical operation before.
