Background: Non-intubated thoracoscopic surgery can be performed under sedation using adjuvant regional anesthesia, however, the benefits of non-intubated thoracoscopic surgery under sedation have not yet been completely verified. In this study, we compare the perioperative safety and pain complaints of sedation without intubation in thoracoscopic bullectomy with that of conventional general anesthesia with double-lumen intubation and mechanical ventilation. Methods: Forty-one patients with primary spontaneous pneumothorax who were scheduled for thoracoscopic bullectomy were enrolled in this study. Twenty-one patients were under sedation anesthesia (SA group) and 20 patients were under general anesthesia (GA group). In SA group, sedation was done with dexmedetomidine (a loading dose of 1 μg/kg for 10 min and then maintained in dosages of 0.3-1 μg/kg/h) and ketamine (2-4 mg/kg/h intraoperatively). Meanwhile, in GA group, induction with propofol and rocuronium, intubation with double lumen endotracheal tube and maintenance with 1.0-2.5% sevoflurane was done. In both groups, thoracoscopic bullectomy was performed in the same manner and all operations were conducted by single surgeon. Time for anesthesia [including emergence time and post-anesthesia care unit (PACU) recovery time] and operation, postoperative pain, sore throat, hoarseness, adverse events (nausea, vomiting, hypotension and bradycardia), dose of rescue analgesic drug used for 24 hours post-operatively and perioperative arterial blood gas analysis were recorded. Results: The times for anesthesia, operation and emergence were significantly shorter in SA than GA. Incidence of sore throat were significantly lower in SA. The difference of other adverse events in the two groups was not significant. Conclusions: Our study demonstrated that compared to double-lumen intubation with general anesthesia, non-intubation with sedation for bullectomy for primary spontaneous pneumothorax was safe and efficient to reduce perioperative time.
