不同静脉麻醉药对罗库溴胺快速诱导气管插管的影响   总被引:1,自引:0,他引:1  
目的:观察硫贲妥钠、依托咪酯以及异丙酚麻醉诱导对罗库溴铵的插管条件和神经肌肉阻滞程度的影响。方法:选择39例全麻择期手术患者,ASAⅠ~Ⅱ级,随机分为三组,分别采用硫贲妥钠5.0mg.kg-1、依托咪酯0.3mg.kg-1及异丙酚1.5~2.0mg.kg-1静脉诱导,静注罗库溴铵60s后行气管插管。记录气管插管即刻的T1和T4/T1值、插管时间,记录血流动力学参数变化、脉搏血氧饱和度,根据气管插管评分标准进行插管评分。结果:各组病人气管插管即刻的T1和T4/T1及插管时间组间比较无明显差异(P>0.05),三组病人在静注罗库溴铵后60s气管插管条件综合评分均为优良(P>0.05),但是依托咪酯比硫贲妥钠和异丙酚气管插管反应略少。结论:依托咪酯伍用罗库溴铵在静注后60s行快速诱导插管略优于硫贲妥钠和异丙酚。如果患者禁忌使用琥珀胆碱可以改用依托咪酯与罗库溴铵来完成快速诱导和气管插管。  相似文献

Background: Sevoflurane and propofol are effective cardioprotective anaesthetic agents, though the cardioprotection of propofol has not been shown in humans. Their roles and underlying mechanisms in anesthetic postconditioning are unclear.Mitochondrial permeability transition pore (MPTP) opening is a major cause of ischemia-reperfusion injury. Here we investigated sevoflurane- and propofol-induced postconditioning and their relationship with MPTP. Methods: Isolated perfused rat hearts were exposed to 40 min of ischemia followed by 1 h of reperfusion. During the first 15 min of reperfusion, hearts were treated with either control buffer (CTRL group) or buffer containing 20 μmol/L atractyloside (ATR group), 3% (v/v) sevoflurane (SPC group),50 μmol/L propofol (PPC group), or the combination of atractyloside with respective anesthetics (SPC ATR and PPC ATR groups). Infarct size was determined by dividing the total necrotic area of the left ventricle by the total left ventricular slice area (percent necrotic area). Results: Hearts treated with sevoflurane or propofol showed significantly better recovery of coronary flow,end-diastolic pressures, left ventricular developed pressure and derivatives compared with controls. Sevoflurane resulted in more protective alteration of hemodynamics at most time point of reperfusion than propofol. These improvements were paralleled with the reduction of lactate dehydrogenase release and the decrease of infarct size (SPC vs CTRL: (17.48±2.70)% vs (48.47±6.03)%,P<0.05; PPC vs CTRL: (35.60±2.10)% vs (48.47±6.03)%, P<0.05). SPC group had less infarct size than PPC group (SPC vs PPC:(17.48±2.70)% vs (35.60±2.10)%, P<0.05). Atractyloside coadministration attenuated or completely blocked the cardioprotective effect of postconditioning of sevoflurane and propofol. Conclusion: Postconditioning of sevoflurane and propofol has cardioprotective effect against ischemia-reperfusion injury of heart, which is associated with inhibition of MPTP opening. Compared to propofol, sevoflurane provides superior protection of functional recovery and infarct size.  相似文献

目的:探讨单独丙泊酚静脉麻醉下胃肠镜检查的可行性、安全性及临床效果。方法:自2009年3月至2009年9月,对800例患者应用丙泊酚进行无痛胃肠镜检查,另外1000例患者进行常规胃肠镜检查,观察两组胃肠镜检查的安全性和效果,检查完后由患者和内镜医生阅读并填写问卷调查表。结果:所有胃肠镜检查均顺利完成。检查前无痛组心理压力明显小于常规组,检查中无痛组不良反应明显比常规组少,两组间对比有显著性统计学差异(P≤0.05);检查后不良反应对比无显著性差异(P〉0.05)。常规组检查中出现血压升高和心率增快。无痛组检查中血压、心率均有不同程度下降,与检查前比较有显著差异(P≤0.05),与常规组比较亦存在显著差异(P≤0.05),但多在正常范围,且为一过性,无须特殊处理,检查结束后迅速自行恢复。两组绝大多数患者检查前、中、后SaO2无明显差异,无痛组少部分患者出现SaO2降低,经积极处理迅速恢复正常。结论:单独丙泊酚静脉麻醉下胃肠镜检查是一种安全、舒适、有效的方法,但应注意严格掌握适应证与禁忌证,加强并发症的监测和处理。  相似文献

Objective: The aim of this paper is to compare the propofol concentration in plasma and cerebrospinal fluid (CSF) in patients scheduled for intracranial tumor removal and anaesthetized using propofol as part of a total intravenous anaesthesia technique. Methods: Twenty-seven patients (ASA I–II) scheduled for elective intracranial tumor removal were studied. Anesthesia was induced with 2 mg/kg propofol for 5 min and infused at 10 mg/(kg·h) for 5 min and then stopped. CSF and arterial blood were collected simultaneously before infusion of propofol and at different time points after infusion of propofol according to bispectral index (BIS) values. Concentrations of propofol in plasma and CSF were measured by HPLC with fluorescence detection. The correlation coefficient and regression equation between plasma and CSF concentration of propofol were worked out by linear simple regression. Results: The propofol CSF concentration that we measured was 1.46% of the plasma concentration. The coefficient of relation between plasma and CSF concentration was 76.7%. Conclusions: The propofol CSF concentration was positively correlated with and much lower than the plasma concentration. Discrepancies may result from high plasma protein binding of propofol, intracranial pathology and sampling volume.

Objective: To compare the effects of epidural anesthesia with 1.5% lidocaine and 0.5% ropivacaine on propofol requirements, the time to loss of consciousness (LOC), effect-site propofol concentrations, and the hemodynamic variables during induction of general anesthesia guided by bispectral index (BIS) were studied. Methods: Forty-five patients were divided into three groups to receive epidurally administered saline (Group S), 1.5% (w/w) lidocaine (Group L), or 0,5% (w/w) ropivacaine (Group R) Propofol infusion was started to produce blood concentration of 4 lag/ml. Once the BIS value reached 40-50, endotracheal intubation was facilitated by 0.1 mg/kg vecuronium. Measurements included the time to LOC, effect-site propofol concentrations, total propofol dose, mean arterial blood pressure (MABP), and heart rate (HR) at different study time points. Results: During induction of anesthesia, both Groups L and R were similar for the time to LOC, effect-site propofol concentrations, total propofol dose, MABP, HR, and BIS. The total doses of propofol administered until 1 min post-intubation were significantly less in patients of Groups R and L compared with Group S. MABP and HR were significantly lower following propofol induction compared with baseline values in the three groups, or MABP was significantly increased following intubation as compared with that prior to intubation in Group S but not in Groups R and L while HR was significantly increased following intubation in the three groups. Conclusion: Epidural anesthesia with 1.5% lidocaine and 0.5% ropivacaine has similar effects on the time to LOC, effect-site propofol concentrations, total propofol dose, and the hemodynamic variables during induction of general anesthesia.  相似文献

Objective: We compare the cardioprotective effects of anesthetic preconditioning by propofol and/or isoflurane in rats with ischemia-reperfusion injury. Methods: Male adult Wistar rats were subjected to 60 min of anterior descending coronary artery occlusion followed by 120 min of reperfusion. Before the long ischemia, anesthetics were administered twice for 10 min followed by 5 min washout. Isoflurane was inhaled at I MAC (0.016) in I group, whereas propofol was inhaled intravenously at 37.5 mg/(kg.h) in P group. A combination ofisoflurane and propofol was administered simultaneously in I+P group. Results: In control (without anesthetic preconditioning, C group), remarkable myocardial infarction and apoptosis accompanied by an increased level of cardiac troponin T were noted 120 rain after ischemia-reperfusion. As compared to those of control group, I and P groups had comparable cardioprotection. In addition, I+P group shares with I and P groups the comparable cardioprotective effects in terms of myocardial infarction and cardiac troponin T elevation. Conclusion: A combination of isoflurane and propofol produced no ad-ditional cardioprotection.  相似文献
