Application of oxycodone hydrochloride injection on anesthesia and postoperative analgesia in patients undergoing radical resection of colorectal cancer / 医学研究生学报

ABSTRACT

Objective　The choice of perioperative analgesic drugs for radical resection of colorectal cancer is controversial. The purpose of this paper is to investigate the efficacy of oxycodone hydrochloride injection on anesthesia and postoperative analgesia in patients with radical resection of colorectal cancer, to provide a basis for the selection of such surgical analgesics.　Methods　Between July 2017 and December 2017, selection of 38 patients with colorectal cancer underwent elective open surgical operation in the Eastern Theater General Hospital, the age range was 18～65 years, the BMI range was 18～25 kg/m2, the ASA was Ⅱ or Ⅲ grade, who were divided to two groups according to randomized, single blind and controlled methods, the oxycodone group was group O, the sufentanil was group S, each group had 19 cases. Oxycodone 0.3 mg/kg (group O) and sufentanil 0.3 μg/kg (group S) were given at general anesthesia induction in both groups.The anesthesia maintenance medication was consistent in both groups. When sewing skin, the group O were given oxycodone 0.15 mg/kg, the group S were given sufentanil 0.15 μg/kg , and who were given PCIA postoperative, the group O were given oxycodone 1 mg/kg and Azhasi 10 mg, while the group S were given sufentanil 2.5 μg/kg and Azhasi 10 mg, which were diluted with normal saline to 100 mL. The NRS score postoperative and the Ramsay sedation scores were recorded when extubating（T1）, 4 hours after operation（T2）, 12 hours after operation（T3）, 24 hours after operation（T4） and 48 hours after operation（T5）in two groups ; the plasma cortisol, MAP(mean arterial pressure) and HR(heart rate) before and after intubation in two groups were recorded; the extubation time, first bowel ventilation time, PCIA compressions and adverse reactions in two groups were recorded.　Results　The age, weight, anesthesia duration had no significant difference in two groups (P> 0.05). Compared with group S, the NRS scores were obvious decreased in group O at all time points（P 0.05). Compared with before intubation, the MAP were both decreased at intubation and after intubation 5min in group O (P 0.05) .　Conclusion　Compared with sufentanil, oxycodone was safer and more effective on general anesthesia induction and postoperative analgesia in radical resection of colorectal cancer.
