Abstract:Objective To explore the effects of butorphanol combined with propofol in painless gastrointestinal endoscopy.Methods 250 patients who underwent painless gastrointestinal endoscopy were selected and randomly divided into two groups: butorphanol combined with propofol group (group B) and sufentanil combined with propofol group (group S), with 125 patients in each group. Before anesthesia induction, butorphanol 7.5 μg/kg was injected intravenously in group B, while sufentanil 0.1 μg/kg was injected intravenously in group S. Give 5 min onset time, propofol 1.5 ~ 2.0 mg/kg was administrated intravenously in both groups, followed by a continuous intravenous infusion at a rate of 4.0 ~ 6.0 mg/(kg·h) during the endoscopy. The incidence of body movement and other sedation-related adverse events, the cumulative dosage of propofol, recovery time, departure time, and postoperative comfort evaluation were recorded.Results The incidence of body movement, cough, respiratory depression, propofol injection pain, postoperative nausea and vomiting in group B were lower than those in group S, the degree of propofol injection pain in group B was milder than that in group S, and the postoperative abdominal pain score in group B was lower than that in group S, the differences were statistically significant (P < 0.05). There were no statistically significant differences in the cumulative dosage of propofol, the incidence of hiccup, recovery time, departure time, visual analogue scale (VAS) of postoperative fatigue degree and the incidence of hypotension, bradycardia, dizziness, drowsiness between the two groups (P > 0.05).Conclusion Butorphanol combined with propofol can improve the sedation and analgesia effect in painless gastrointestinal endoscopy, and reduce the adverse reactions. It is worthy of clinical application.
