Abstract：Objective To investigate the effect of different volume of fresh gas on postoperative analepsia period of general anesthesia with sevoflurane in patients undergoing abdominal surgery. Methods 181 ASAⅠ-Ⅱpatients aged 20 - 70 undergoing elective abdominal surgery were divided into group A (112 patients) and group B (69 patients). Both groups received sevoflurane general anesthesia during surgery. At the end of surgery , group A received fresh gas for no more than 2L/min , and group B received the gas for more than 2L/min. The recovery time of spontaneous breathing, eye-opening time (from the end of surger to eye opening), and time of endotracheal extubation (from the end of surgery to endotracheal extubation ) were recorded. Results There were no significant differences in the recovery time of spontaneous breathing ,eye-opening time and time of endotracheal extubation between group A and group B (P > 0.05); Gender and time of intraoperative continuous uses of sevoflurane had effects on the recovery time of spontaneous breathing , which showed statistical significances (P < 0.05). Conclusions Uses of fresh gas for no more than 2L/min or more than 2L/min after surgery have no marked effects on the recovery time. However , gender and time of intraoperative continuous uses of sevoflurane may have effects on the recovery time of spontaneous breathing.
