ObjectiveTo compare the effects of different doses of butorphanol combined with propofol anesthesia on the analgesic effect and recovery time in patients undergoing hysteroscopy. MethodsA total of 150 cases of patients received hysteroscopy were selected and randomly divided into group A, group B and group C, with 50 cases in each group. Group A, B, C were injected with butorphanol for 10 μg/kg, 15 μg/kg, 20 μg/kg, respectively. Three minutes later, all three groups received intravenous injection of propofol 2.0 mg/kg. Hysteroscopy was performed after patients falling asleep, and propofol was additionally administrated according to the body movement in patients during the operation. The operative time, propofol dosage, incidence of intraoperative body movement and postoperative recovery time were recorded in three groups. The numerical rating scale (NRS) was used to evaluate the degree of uterine contraction pain 30 minutes after recovery. ResultsThere was no statistically significant difference in operation time among the three groups (P＞0.05). Compared with group B, C, group A yielded a significantly larger dosage of propofol, and a higher NRS score of uterine contraction pain 30 minnutes after recovery (all P＜0.05), but there were no statistically significant differences in the above indexes between group B and group C (all P＞0.05). Group B yielded shorter postoperative recovery time as compared with group A and group C, while group A yielded higher incidence of intraoperative body movement compared to group B and group C (all P＜0.05). There was no statistically significant difference in the incidence of intraoperative body movement between group B and group C (P＞0.05). ConclusionDuring hysteroscopy, using butorphanol at a dosage of 15 μg/kg combined with propofol for anesthesia has a definite anesthetic effect, which can significantly shorten the postoperative recovery time, reduce the dosage of propofol and the degree of postoperative uterine contraction pain.
