Effect of intrathecal parecoxib sodium in bone tumor pain of rats / 中国医师进修杂志

Objective To investigate the effect of intrathecal parecoxib sodium in bone tumor pain of rats. Methods Bone tumor pain was induced by injection of MRMT-1 tumor cells (1 × 104/L) into the tibia of female SD rats under sevoflurane anesthesia. The development of bone tumor was monitored by radiological study, and histological sections stained with hematoxylin and eosin. At 3 d after MRMT-1 tumor cell injection, a PE-10 catheter was inserted into the intrathecal space for drug administration. At 10 d after MRMT-1 tumor cell injection, rats were randomly divided into 5 equal groups, control group, parecoxib sodium 0.1, 0.3, 1.0 and 3.0 g/L group. For pain assessment, a withdrawal threshold was measured using von Frey filament being applied to the tumor cell inoculation site. The effects of intrathecal saline or parecoxib sodium were investigated. Results Intra-tibial injection of MRMT-1 tumor cells produced a bone tumor in radiologic and pathologic findings.Also, the paw withdrawal threshold was significantly decreased(mechanical allodynia).Percentage of the maximal possible effect (% MPE) of control group and parecoxib sodium 0.1, 0.3, 1.0 and 3.0 g/L group was (13.89 ± 4.17)%,(7.54 ± 3.91)%,(57.47 ± 11.47)%,(85.72 ± 9.42)% and(100.00 ± 0.00)%,compared with control group, intrathecal parecoxib sodium dose-dependently increased the withdrawal threshold (P<0.05).Conclusions Intrathecal parecoxib sodium reduces bone tumor-related pain behavior.

Effect of parecoxib on hippocampal inflammation following partial hepatectomy in rats / 临床麻醉学杂志

Objective To investigate the effect of parecoxib on hippocompal inflammation following partial hepatectomy in aged rats.The effects of selective COX-2 inhibitor (parecoxib) on hippocampal inflammation were also evaluated.Methods Seventy male rats,aged 20 months,weighing 500-600 g,were randomly divided into three groups: control (n=10),surgery (n=30),and parecoxib (n=30).Control animals received sterile saline to control for the effects of injection stress.Rats in the surgery group received partial hepatectomy under isoflurane anesthesia and sterile saline injection.Rats in the parecoxib group received surgery and anesthesia similar to surgery group rats,and parecoxib treatment.On postanesthetic day 1,3 and 7,animals were euthanized to assess the hippocampal COX-2 expression,PGE2 production and caspase-3 expression.Results Surgery significantly increased the expression of COX-2 mRNA and protein expression,PGE2 production and caspase-3 protein expression on day 1 postoperatively (P<0.01),until day 3 (P<0.05) compared to control group.Parecoxib treatment group significantly suppressed COX-2 mRNA and protein expression,PGE2 production and caspase-3 protein expression on postoperative day 1 and day 3 (P<0.05 or P<0.01),in comparison with the surgery group.There was no significant difference between control group and other groups of the expression of COX-2 mRNA and protein expression,PGE2 production and caspase-3 protein expression on day 7.Conclusion Partial hepatectomy induces a short-term hippocampal inflammatory response in the rats.Parecoxib suppressed the hippocampal inflammation via the down-regulation of COX-2 mRNA and protein,PGE2 and caspase-3 protein in rats following partial hepatectomy.

Observation of Dezocine Combined with Parecoxib on Prevention of Emergence Pain and Agitation in Pa-tients Undergoing Radical Hysterectomy / 中国药师

Objective:To compare the preventive effects of dezocine or parecoxib used alone or combination on emergence pain and agitation in the patients undergoing radical hysterectomy. Methods: Sixty ASA Ⅰ~Ⅱ patients undergoing radical hysterectomy were randomly divided into three groups. At the time of sewing incision, the dezocine group (group D, n=20) received dezocine in-travenous injection at the dosage of 0. 1 mg·kg-1, the parecoxib group (group P, n=20) received parecoxib intravenous injection at the dosage of 0.8 mg·kg-1, and the combination group (group DP, n=20) received 0.1 mg·kg-1dezocine and 0.8 mg·kg-1 parecoxib. When the operation was finished, the patients were transferred to the recovery room with endotracheal tubes, and recovered and extubated without the administration of reversal agents. Visual analogue scale ( VAS) for pain and Aono' s four-point scale for e-mergence agitation ( EA) were measured. The recovery time, extubation time, VAS, degree of EA and side effects such as nausea, vomiting, respiratory depression and hypersomnia during the emergence were also evaluated and recorded. Results:There were no sig-nificant differences in recovery time and extubation time among the three groups (P >0. 05). The VAS score and degree of EA in group DP were lower than that in group D (4. 65 ± 1. 69) and group P (5. 95 ± 1. 82) (P0. 05), and no side effects such as nausea, vomiting, respiratory depression and hypersomnia were detected during the emergence. Conclusion:Intravenous injection of 0. 1 mg·kg-1 dezocine combined with 0. 8 mg·kg-1 parecoxib at the time of sewing incision shows effective analgesia and emergence agitation reduction without obvious complications in the patients undergoing radical hysterecto-my.

Clinical Observation of Different Patient-controlled Analgesia Modes in Laparoscopic Hysteromyomectomy / 中国医科大学学报

Objective To investigate the clinical effect of different patient-controlled analgesia (PCA) modes in patients undergoing laparoscopic hysteromyomectomy.Methods Sixty patients scheduled for a laparoscopic hysteromyomectomy were randomly divided into three groups.All patients received an intravenous infusion of parecoxib sodium (40 mg) as preventive analgesia 15 min prior to the skin incision.Thirty minutes prior to the end of surgery,they received an intravenous injection of sufentanil (0.1 μg/kg) as a loading dose.The following data were collccted:the total dosage of sufentanil,the total and valid frequency of the PCA press,visual analog pain score,sedation score,the incidence of adverse reactions,the incidence of adverse reactions per group.Results Compared to groups 1 and 2,group 0 had the lowest dosage of sufentanil.There was no significant difference in the incidence of adverse reactions between the three groups (P ＞0.05).Conclusion The PCA-only mode,in conjunction with parecoxib sodium as preventive analgesia,was more suitable for patients undergoing laparoscopic hysteromyomectomy.
