ABSTRACT
Objective To observe the effects of oxycodone hydrochloride injection pretreatment on postoperative analgesic and immune function after fracture.Methods 120 patients scheduled to re-ceive orthopedic surgery under general anesthesia were randomly divided into oxycodone hydrochloride in-jection group(groupⅠ)and saline control group(groupⅡ)and 60 cases in each group.GroupⅠreceived pretreatment of 0.1 mg/kg oxycodone hydrochloride injection at 15 min before the end of surgery while groupⅡ received the same volume saline;all accepted postoperative intravenous analgesia postoperative-ly.Monitor visual analogue scores(VAS)at 2,6,12,24,48 h after operation in two groups,postoperative analgesia pressing times in 48 h and the incidence of adverse reactions;record NK cells,CD4 +T lympho-cytes cells,CD8+ T lymphocytes and CD4 +/CD8+ levels at 30min before anesthesia,postoperative 30 min,24 h,48 h.Results Compared with group Ⅱ,VAS scores of group Ⅰ at 2,6 h after operation were lower[(3.3 ± 0.6)vs(4.5 ± 0.7),(2.8 ± 0.5)vs(3.5 ± 0.6)],and 48 h postoperative analgesia press-ing times was less[(6.7 ± 2.2)vs(12.4 ± 2.5)](P<0.05).Compared with groupⅡ,NK cells,CD4 +T cells and CD4 +/CD8 +levels of group Ⅰ at 24 h,48 h after operation were higher[(10.2 ± 1.2)vs (9.1 ± 1.3),(9.6 ± 1.4)vs(8.4 ± 1.3);(40.5 ± 3.1)vs(37.4 ± 2.6),(39.6 ± 3.3)vs(34.3 ± 3.6);(1.6 ± 0.3)vs(1.3 ± 0.2),(1.5 ± 0.3)vs(1.2 ± 0.3)],and CD8+ T lymphocyte cell level was lower[(25.9 ± 2.2)vs(28.9 ± 2.1);(26.7 ± 2.3)vs(29.2 ± 2.5)](P<0.05);and in intra-group comparison,NK cells,CD4 +T cells and CD4 +/CD8 +levels of group Ⅰ,Ⅱ at 24 h,48 h after operation were higher,and CD8 +T lymphocyte cell level was lower(P <0.05). The adverse effects of the two groups had no significant difference(P>0.05).Conclusion Oxycodone hydrochloride injection precon-ditioning on postoperative analgesic after fracture has better effect,it can reduce the degree of postoperative pain and the degree of immune function decreased after the surgery,but it do not increase the adverse re-action,so clinical should be safe and worthy of promotion.
ABSTRACT
Objective To investigate oxycodone hydrochloride injectio in treatment of postoperative laparoscopic cholecystectomy and its effects on analgesia and levels of 5-hydroxytryptamine(5-HT),nitric oxide(NO),substance P(SP).Methods 90 patients of underwent laparoscopic cholecystectomy who received therapy from August 2013 to August 2016 in Hangzhou Tvaditional chinese Medical hospital were selected and randomly divided into observation group and control group,45 cases in each group.Before incision,the observation group were gived intravenous oxycodone hydrochloride injection 0.1mg/kg,the control group were gived intravenous sufentanil 0.2μg/kg.The changes of anesthesia,postoperative pain,adverse reactions and 5-HT,NO and SP after operation were compared between the two groups.ResultsThere was no significant difference in the anesthesia time,operation time,spontaneous breathing recovery time,wake up of time between two groups,after postoperative two,four,24 h,the scores of incision pain,visceral pain in the observation group were lower than the control group,the difference was statistically significant(P<0.05).After the operation,the levels of 5-HT,NO,SP of two groups were changed,the difference was statistically significant(P<0.05),but the results in observation group were lower than the control group,the difference was statistically significant(P<0.05),the total incidence of postoperative adverse reactions in observation group were lower than the control group,the difference was statistically significant(P<0.05).Conclusion Oxycodone hydrochloride injection is well for laparoscopic cholecystectomy,which can effectively reduce the release of 5-HT,NO,SP,relief of postoperative pain,high security.
ABSTRACT
Objective To analyze effect of oxycodone hydrochloride injection preemptive analgesia on serum cellular immune factors and analgesic effect in postoperative patients with humeral fracture surgery.Methods 52 patients treated by surgical treatment of humeral fractures in our hospital were collected.All patients were randomly divided into experimental group and control group,26 cases in each group.Preemptive analgesia drugs were given corresponding, before and 24h after surgery, the serum levels of interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α), venous blood CD4 +T, CD8 +T cells and CD4 +/CD8 + T levels and analgesic effect were detected in all patients.Results After surgery, compared with control group, the serum levels of TNF-αand IL-6 were lower in experimental group (P<0.05); the venous blood CD4 +T cell and CD4 +/CD8 + T levels were higher(P<0.05), CD8 +T cell level was lower in experimental group (P<0.05);the visual analogue scale(VAS) score was significantly lower in 2,4,6,12 and 24h after surgery in experimental group (P<0.05).Conclusions The oxycodone hydrochloride injection preemptive analgesia can significantly inhibit the increase of the serum TNF-αand IL-6 levels, prevent the decrease of immune function, improve the analgesic effect.
