Objective To investigate efficacy between low flow isoflurane and sevoflurane in pediatric laparoscopic surgery. Methods 120 cases of children underwent laparoscopic surgery in our hospital were randomly divided into two groups. 60 patients in isoflurane group were given low-flow isoflurane anesthesia; 60 patients in sevoflurane group were given low-flow isoflurane anesthesia. Heart rate (HR), mean arterial blood pressure (MAP), pulse oxygen saturation (SpO₂), end-tidal partial pressure of carbon dioxide (EtCO₂) at different period, sleep and awakening time, extubation time, and adverse reactions of two groups were observed. Results Heart rate (HR), pulse oxygen saturation (SpO₂), end-tidal partial pressure of carbon dioxide (EtCO₂) of two groups at different period had no significantly difference (P>0.05). Mean arterial blood pressure (MAP) of two groups at different period had significantly difference (P<0.05). The sleep time and recovery time of two groups had no significant difference (P>0.05). The extubation time of sevoflurane was significantly lower than isoflurane group (P<0.05). The adverse reaction rate of sevoflurane was significantly lower than isoflurane group (P<0.05). Conclusion Low flow isoflurane and sevoflurane can be used in pediatric laparoscopic surgery, and the efficacy of sevoflurane is better.
