摘要: 【摘要】 目的 采用随机、双盲、对照的方法观察帕瑞昔布对神经外科开颅术中七氟烷呼气末浓度和麻醉恢复的影响。方法 择期神经外科全麻开颅手术患者137例随机分为: 帕瑞昔布组(P组,n=72 )和对照组(C组,n =65 )。病人入手术室安静后,测三次血压,取三次平均动脉压(MAP)的平均值作为基础值。芬太尼-丙泊酚-维库溴铵麻醉诱导插管。手术开始前10分钟P组和C组分别静注帕瑞昔布40mg(10ml)或生理盐水10ml。切皮前,头皮浸润0.5%罗哌卡因20ml。调节七氟烷吸入药浓度,维持MAP在基础值的-20%~10%之间。记录术中呼气末七氟烷吸、呼浓度,术中及麻醉恢复期各时间点的MAP和HR,术中总入液量、总出液量、出血量、补液量及尿量,观察术后呼之睁眼、指令运动、定向力恢复的时间以及麻醉恢复期并发症。结果 两组患者各个不同观察时间点的七氟醚呼气末浓度以锯骨、剪硬膜、颅内操作时的差异性最大,P组较C组分别降低了10%、12%、7%(p<0.01),止血、缝硬膜、缝皮时的七氟醚呼气末气体浓度,P组较C组降低了约6% (p<0.05),铺手术巾及切皮时的七氟醚呼气末浓度无显著性差异。两组患者术中总入液量、总出液量、出血量及尿量无显著性差异。从停止吸入麻醉到睁眼、指令运动、定向力恢复的时间,P组较C组分别缩短了22%、27%、23%。P组高血压的发生显著低于C组(16.7%vs38.5%,p<0.01),P组寒战的发生也低于C组(2.8%vs12.3%,p<0.05), 两组患者之间心律失常及躁动的发生无显著性差异。结论 手术开始前静注帕瑞昔布40mg能够显著减少术中七氟醚呼气末浓度,维持血流动力学平稳,缩短麻醉恢复时间,减少恢复期的高血压及寒战发生率。

Abstract: 【Abstact】: Objective To investigate the effect of preoperative parecoxib(40mg) on end-tidal concentration of sevoflurane during craniotomy and anesthetic recovery. Methods 137 neurosugical patients , ASA physical I~II , were randomly allocated into two groups to receive paracoxib 40mg ( Group P,n=72) , placebo ( Group C,n=65) . The end-tidal concentration of sevoflurane was measured. The volumes of bleeding , transfusion , fluid infusion and urine were recorded. The time of consciousness , psychomotor and cognitive recoveries from general anesthesia, and complication in recovery after anaesthesia were observed. Results The end-tidal concentration of sevoflurane in group P were reduced 6% at the time of hemostasis,sewing dura matter, sewing skin(P<0.05),and 10%, 12%,7%( P < 0.01) at the time of sawing bone and cutting dura matter,intracalvarium operating(p<0.01) compared to the group C .No different between the groups in the volume of infusion,fluid loss,bleeding and urine. The recovery time of conscious , psychomotor and cognitive from general anesthesia were reduced by 22%,27% and 23% respectively compared to group C( P < 0.01 ) . The incidence of hypertension(16.7%) and the incidence of shivering(2.8%) in the group P were significantlylower than that in group C(38.5% for hypentension and 12.3% for shivering) .there were no difference in the incidence of restlessness and arrhythmia. Conclusion The preoperative application of parecoxib(40mg) can reduce the end-tidal concentration of sevoflurane, smooth the recovery from anesthesia.
