AbstractObjective To evaluate the value of oxycodone hydrochloride for postoperative pain management in patients undergoing patient-controlled intravenous analgesia(PCIA). Methods The medical records on postoperative pain management in our department from January 1 to June 30,2018,were retrospectively analyzed.Totally 136 patients were assigned into oxycodone,sufentanil,or morphine groups according to the opioid used in the PCIA.Patients were assessed for postoperative pain severity(scored with NRS)and adverse reactions 24,36,and 48 hours after surgery.The area under curve(AUC)was calculated. Results The score of pain at exercise was significantly lower in the oxycodone group(2.2±2.4)than in the sufentanil group(3.4±2.1)(t=0.305,P=0.0126)or the morphine group(3.4±1.7)(t=0.104,P=0.0277)36 hours after surgery.AUC at rest was significantly lower in the oxycodone and morphine groups than in the sufentanil group(29.00,27.00,and 40.01,respectively);in contrast,AUC at exercise was significantly lower in the oxycodone group(63.17)than in the sufentanil and morphine groups(82.00 and 80.93,respectively).The consumption of opioids was significantly higher in the sufentanil group[(37.2±16.1),(46.1±24.3),(64.4±33.4)mg]than in the oxycodone group[(20.4±14.8)(t=3.571,P=0.001),(24.2±16.1)(t=4.63,P<0.0001),(34.4±25.1)mg(t=6.409,P<0.0001)]or the morphine group[(16.6±11.7)(t=4.233,P<0.0001),(20.5±14.1)(t=5.250,P<0.0001),(28.8±19.0)mg(t=7.354,P<0.0001)]24,36,48 hours after surgery.The oxycodone group experienced less vomiting(χ 2=11.360,P=0.003)and early termination of PCIA(χ 2=7.914,P=0.019)compared with the other two groups. Conclusions Oxycodone can be used for postoperative PCIA.It can alleviate a variety of postoperative pain,with superior analgesic efficiency and safety to sufentanil and morphine.
