Effectiveness and Safety of Low-flow Sevoflurane Combined with Remifentanil on Anaesthesia of Patients Undergoing Gynaecological Laparoscopic Surgery

Objective: To evaluate the advantages of sevoflurane (low-flow) + remifentanil for patients undergoing gynaecological laparoscopic surgery. Methods: 300 patients admitted for gynaecological laparoscopic surgery between July 2020 and July 2023 were selected and divided equally by random number table, 150 cases were counted in the observation group, and sevoflurane (low-flow) + remifentanil was chosen for maintenance anaesthesia; 150 cases were counted in the reference group, and anaesthesia was maintained only with remifentanil. The anaesthesia indexes, haemodynamics, stress reaction indexes, and adverse reaction rate of the two groups were compared. Results: The anaesthesia indexes of the observation group were better than those of the reference group (P < 0.05). Before 5 min of anaesthesia (T1), there was no difference between the haemodynamics and stress reaction indexes of the two groups (P > 0.05). After 30 min of pneumoperitoneum (T2) and immediately after the end of surgery (T3), the hemodynamic and stress indicators of the observation group were lower than those of the reference group (P < 0.05). The adverse reaction rate of the observation group was lower than that of the reference group (P < 0.05). Conclusion: Sevoflurane (low-flow) + remifentanil can improve the anaesthesia indexes of gynecological laparoscopic surgery patients, stabilize intraoperative haemodynamics, reduce the stress reaction, and the safety of medication is high.
