To study the effect of oxycodone hydrochloride combined with parecoxib sodium on hyperalgesia after remifentanil combined anesthesia surgery. Eighty patients with remifentanil combined anesthesia were selected and randomly divided into group I and group II. Group I received combined remifentanil anesthesia alone, and group II received oxycodone hydrochloride combined with parecoxib sodium. The incidence of adverse reactions such as chills and restlessness, pain score at 0.5-4h postoperatively, and differences in breathing recovery time, extubation time, remifentanil and propofol dosages were compared between the two groups. Compared with group I, the incidence of adverse reactions such as chills and agitation was lower in group II (P < 0.05). The pain score in group II was lower at 0.5-4h after operation (P < 0.05). The breathing recovery time, extubation time, and the dosage of remifentanil and propofol were similar in the two groups (P > 0.05). Oxycodone hydrochloride combined with parecoxib sodium has a great impact on hyperalgesia after remifentanil combined anesthesia surgery, which can effectively play an analgesic effect, reduce postoperative hyperalgesia, and reduce postoperative agitation and other complications.

Li, Jun published the artcileInfluences of parecoxib sodium on pulmonary oxygenation function in patients after valve replacement under cardiopulmonary bypass, Computed Properties of 198470-85-8, the publication is Jilin Yixue (2014), 35(34), 7638-7640, database is CAplus.

The influences of parecoxib sodium on pulmonary oxygenation function in patients after valve replacement under cardiopulmonary bypass (CPB) were evaluated. Sixty-three patients suffering from valve replacement under CPB were collected and divided into three groups: the control group (group I), parecoxib sodium 20 mg group (group II) and parecoxib sodium 40 mg group (group III). The changes of end-tidal CO2 pressure (P_ETCO₂), arterial O₂ concentration (CaO₂), pulmonary alveolar-arterial O₂ pressure (PA-aO₂), oxygenation index (OI), spontaneous breathing frequency and ventilator assisted ventilation time in these patients were observed and compared. In group I, the levels of PA-aO₂ and OI after surgery were significantly increased as compared before surgery. And the levels of PA-aO₂ and OI in group III were significantly lower than those in group I and group II. The most stable spontaneous breathing frequency and the lowest incidence rate of dry/moist rales were observed in group III. It indicated that parecoxib sodium had protective effects on pulmonary injury and oxygenation function improvement in patients after valve replacement under CPB.

Liang, Shujun published the artcileEffect of sequential celecoxib with parecoxib sodium on perioperative analgesia and joint function recovery of total hip replacement, SDS of cas: 198470-85-8, the publication is Hebei Yixue (2015), 21(11), 1869-1872, database is CAplus.

Objective: To observe and explore the analgesic effect of sequential celecoxib with parecoxib sodium during unilateral total hip arthroplasty (THR) during perioperative period, and to compare with the effect of tramadol. Methods: A total of 102 unilateral THR patients selected from 2011 to May 2014 were randomly divided into a study group (52 cases) and a control group (50 cases). In the study group, 40 mg parecoxib sodium was injected i.v. 30 min before anesthesia induction, and THR surgery was performed after routine anesthesia, analgesia pump was routinely used for analgesia for 2 days after surgery, and 40 mg parecoxib sodium was injected i.v. 3 h after surgery, 2 times/d, for consecutive days, and on the 3rd postoperative day, the celecoxib capsules were taken orally at 200 mg twice a day until discharged. In the control group, 100 mg tramadol injection was injected, and on the 3rd postoperative day, tramadol tablets were taken orally, and other analgesic regimens during the perioperative period were the same as the study group. The visual analog pain (VAS) score and passive active Harris hip score were compared in the perioperative resting state between the two groups. Adverse drug reactions were recorded during analgesia. Results: Within 24 h after operation, the number of analgesia pump compressions in the study group (10.2 ± 3.5) was significantly less than that in the control group (15.8 ± 5.5) (u = 6.108, P < 0.001). The VAS scores at 12 h, 24 h, 48 ??hours, 72 h, and 96 h in the study group were significantly lower than those in the control group (P < 0.05). The Harris hip scores at 7 and 14 days after surgery in both groups were significantly improved compared with those before surgery. The scores at 7 and 14 days after surgery in the study group were significantly higher than those in the control group (P < 0.05). The perioperative nausea, vomiting, dizziness, drowsiness, urinary retention and other adverse drug reactions in the study group were lower than those in the control group, without statistically significant difference (P > 0.05). Conclusion: Sequential celecoxib with parecoxib sodium during THR during perioperative period can significantly reduce the pain of patients, reduce the dose of opioids in the analgesia pump, and help patients to exercise hip function as soon as possible, and has low incidence of the adverse reactions compared with tramadol.
