ABSTRACT
Objective To compare the perioperative application of sufentanil and oxycodone in patients undergoing laparoscopic surgery for gastric or colorectal cancer. Methods 59 patients were selected and randomly divided into group O and group S. Anesthesia was induced with sufentanil 0.3 μg/kg in group S and oxycodone 0.3 mg/kg in group O. Anesthesia was maintained with sevoflurane balanced anesthesia. When heart rate or blood pressure reached 20% over the baseline, additional dose of oxycodone 0.1 mg/kg was given in group O and sufentanil 0.1 μg/kg in group S. 30 minutes before the end of surgery, patients in group S received sufentanil 0.1 μg/kg and group O with oxycodone 0.1 mg/kg separately. Two hours in the PACU, a rescue dose of sufentanil 0.1 μg/kg or oxycodone 0.1 mg/kg was given to the patients with VAS score bigger than 4. Hemodynamic index, VAS score, Ramsay score, adverse responses and analgesics rescue were recorded. Results No difference was found in hemodynamic index, VAS score and analgesics rescue between the two groups (P>0.05). Ramsay score of group S is lower than that of group O (P=0.014). Induction period bucking incidence in group O was obviously lower than that in group S(P=0.002). The incidence of emergency agitation in group O was significantly lower than that in group S(P=0.045).There was no significant difference in respiratory depression, postoperative nausea and vomiting between two groups (P>0.05). Conclusion Compared with sufentanil, oxycodone significantly reduced the incidence of bucking and emergency agitation. Oxycodone provided better sedation to patients who received laparoscopic surgery for gastric or colorectal cancer.
