Effect of Different Drugs on End-tidal Carbon Dioxide during Rodent CPR

The purpose of this study was to investigate the effect of nonadrenergic agents on cardiopulmonary resuscitation (CPR) and end-tidal CO2(ETCO2)during CPR in a rodent model. Our results suggested that: 1) coronary perfusion pressure (CPP) after drugs infusion was increased significantly by methoxamine, arginine vasopresin (AVP) and angiotension- Ⅱ(ANG- Ⅱ), but not by endothelin-1 (ET-1): 2) ETCO2 prior to defibrillation was decreased significantly by a pure a1 adrenergic agents,methoxamine and were increased significantly by non-adrenergic agents, ANG-Ⅱ and ET-1 during rodent CPR;3) a significant positive correlation between ETCO2 and CPP was observed in AVP group, suggesting that AVP have little effect on pulmonary circulation; and 4) methoxamine, AVP and ANG-Ⅱ have similar effect on resuscitability during rodent CPR.

黄芪汤加减治疗急性加重期慢性阻塞性肺疾病疗效研究

目的:探讨黄芪汤加减治疗慢性阻塞性肺疾病急性加重期(AECOPD)的临床疗效。方法:采用随机数字表法将166例AECOPD患者随机分为常规组和观察组各83例。常规组采用常规西医方法治疗,观察组在常规组的基础上给予黄芪汤加减治疗。观察两组治疗前后第1秒用力呼气量(FEV1)、用力肺活量(FVC)、FEV1占FVC的百分比(FEV1/FVC%)、动脉血氧分压(PaO 2)、动脉血二氧化碳分压(PaCO 2)、肿瘤坏死因子-α(TNF-α)、白细胞介素-1β(IL-1β)、白细胞介素-6(IL-6)水平。结果:两组治疗后FEV1、FEV1/FVC、PaO 2水平与治疗前相比较均显著升高(P<0.05),且观察组与同期常规组相比较均显著升高(P<0.05);两组治疗后PaCO 2、TNF-α、IL-1β、IL-6水平与治疗前相比较均显著降低(P<0.05),且观察组与同期常规组相比较均显著降低(P<0.05)。结论:黄芪汤加减治疗AECOPD可降低患者炎症反应水平,改善动脉血气和肺功能,提高治疗效果,值得临床应用。

丙泊酚目标靶控输注用于颅内动脉瘤介入治疗麻醉诱导的临床观察

目的 观察丙泊酚目标靶控输注用于颅内动脉瘤介入治疗麻醉诱导过程中对血流动力学的影响.方法 择期行颅内动脉瘤介入治疗患者90例,按随机数字表法分为三组：对照组（C组）、血浆药物浓度靶控输注组（P组）和效应室药物浓度靶控输注组（E组）,每组30例.C组采用丙泊酚2 mg/kg单次静脉推注;P组设定丙泊酚血浆靶浓度为4μg/ml;E组设定丙泊酚效应室靶浓度为4 μg/m],三组均采用瑞芬太尼浓度为4 ng/ml的血浆靶控输注,静脉推注顺阿曲库铵0.2 mg/kg.持续监测呼气末二氧化碳分压、脑电双频指数、平均动脉压（MAP）、心率（HR）、心电图、脉搏血氧饱和度及生命体征.记录各组患者诱导前（T0）、插管即刻（T1）、插管后1 min （T2）、3 min（T3）、5 min（T4）、10 min（T5）的MAP和HR,记录血流动力学异常发生率及血管活性药物使用情况.结果 三组T0时MAP及HR比较差异无统计学意义（P＞0.05）.三组T1时MAP及HR均显著低于本组T0,差异有统计学意义（P＜0.05）;P组T1时MAP及HR显著低于E组和C组,差异有统计学意义（P＜0.05）.P组使用血管活性药物例数显著低于C组[6.7％（2/30）比40.0％（12/30）],差异有统计学意义（P＜0.01）.结论 丙泊酚血浆药物浓度作为目标靶控输注浓度更适合颅内动脉瘤介入手术患者的麻醉诱导.
