Abstract:Objective To observe the clinical effect of prophylactic analgesia of Nalbuphine combined with Ketorolac on postoperative pain and quality of recovery in patients underwent endoscopic sinus surgery.Methods 46 patients with nasal endoscopic septal deviation orthodontic treatment from June 2019 to April 2020 were selected and randomly divided into two groups: Nalbuphine combined with Ketorolac group (NK group) and Ketorolac control group (C group), with 23 patients in each group. Patients in each group underwent prophylactic analgesia 10 minutes before induction of anesthesia. The NK group was given intravenous Nalbuphine 0.13 mg/kg and Ketorolac 30 mg, and the C group was given intravenous Ketorolac 30 mg. During the operation, Propofol and Remifentanil were used for intravenous anesthesia. Record the visual analogue scale (VAS) in 24 h postoperatively; record the consumption of remedial analgesic drugs and the analgesic rate at 24 h postoperatively; record the Ricker sedation-restlessness scale (SAS) in 24 h; Record the scores of 40-item quality of recovery questionnaire (QoR-40) at 19 to 21 o’clock at 1 day before the operation (T0 ), 1 day after operation (T1 ) and 2 days after operation (T2 ), and the incidence of adverse reactions 24 hours after operation.Results The NK group had VAS scores at 2 h, 4 h, 8 h, 12 h and 24 h after surgery, consumption of salvage analgesics at 24 h after surgery, salvage analgesia rate at 24 h after surgery, and 2 h, 4 h, 8 h, and 12 h after surgery SAS scores were lower than those in group C, and the differences were statistically significant (P < 0.05); The physical comfort, pain, and total scores of QoR-40 scale at T1 and the physical comfort, self care ability, psychological support, pain, and total scores of QoR-40 scale at T2 in NK group increased, and the differences were statistically significant (P < 0.05); The incidence of adverse reactions 24 hours after operation of the two groups were not statistically significant (P > 0.05).Conclusion Nalbuphine combined with Ketorolac has achieved the purpose of preventive analgesia and promoted early recovery after nasal endoscopic surgery.
