ObjectiveTo study the feasibility of using propofol and remifentanil for reduction of shoulder joint dislocation in the conscious elderly patients, and compare its efficacy with brachial plexus block anesthesia. MethodsSeventy elderly patients (American Sociaty of Anesthesiologist physical statusⅠ-Ⅱ) who underwent shoulder dislocation reduction in our hospital between August 2011 and December 2013 were randomly divided into two groups, each group having 35 cases. Patients in group A received brachial plexus nerve block anesthesia downlink gimmick reset, while patients in group B received the use of remifentanil-propofol and lidocaine compound liquid intravenous drop infusion for anesthesia downlink manipulative reduction. After successful anesthesia, two groups of patients were treated with traction and foot pedal method (Hippocrates) to reset. We observed the two groups of patients in the process of reduction, and recorded their hemodynamic changes, reset time, discharge time, postoperative satisfaction, intra-operative memory, breathing forgotten (breathing interval was longer than 15 seconds) and visual analogue scale (VAS) scores, and then comparison was made between the two groups. ResultsPatients in both the two groups successfully completed manipulative reduction. Compared with group A, patients in group B had more stable hemodynamic indexes during the process of reduction, shorter reduction time, better anesthesia effect and higher postoperative satisfaction degree, and the differences were statistically significant (P<0.05). There was no significant difference in terms of time of leaving the operation room between the two groups (P>0.05). VAS score was higher in group A than that in group B (P<0.05). The occurrence of intra-operative memory amnesia and breathing forgotten phenomenon existed in part of the patients after operation in group B, but they did not occur in patients in group A. ConclusionRemifentanyl propofol-lidocaine compound fluid can be safely used in conscious elderly patients for shoulder joint dislocation reconstructive surgery, and it functions quickly with complete analgesia and stable hemodynamic indexes.
The present study was to investigate the effects of infusing remifentanil-poly-caprolactone (REM-PCL) through the abdominal aorta on spinal cord ischemia reperfusion injury (SCIRI). The model of SCIRI was created by clamping the infrarenal aortic in thirty-six New Zealand white rabbits, which were randomly divided into sham group (group S), control group (group C), and REM-PCL group (group R) with 12 rabbits in each one. The spinal cord microcirculatory blood flow (SCMBF) and blood flow rate (BFR) were monitored before ischemia, 15 min, 30 min, 60 min and 120 min after reperfusion, respectively. Neurologic Function was evaluated before ischemia, 6h, 12h and 24h after reperfusion. The concentration of serum neuron-specific enolase (NSE), interleukin-lβ (IL-lβ) and interleukin-8 (IL-8) were monitored before ischemia, 45 min after ischemia, 30 min, 60 min, 6 h, 12 h and 24 h after reperfusion. The abnormal rate of motor neuron of spinal cord tissues and the level of superoxide dismutase (SOD), reactive oxygen species (ROS), glutathione peroxidase (GSH-PX), malondialdehyde (MDA), total anti-oxidation capacity (T-AOC) and mitochondrial swelling degree (MSD) in neural mitochondria were determined before ischemia, 45 min after clamping, 60 min and 120 min after reperfusion. As a result, the neural mitochondrial SOD, GSH-PX and T-AOC decreased while ROS, MDA, MSD, IL-lβ, IL-8 and NSE distinctly increased after clamping of the abdominal aorta as compared to the value before ischemia in group C (P < 0.01). Neurologic function scores recovered more rapidly in group R than those in group C during reperfusion (P < 0.01). The neural mitochondrial SOD, GSH-PX and T-AOC were distinctly higher while ROS, MDA, MSD, IL-lβ, IL-8 and NSE were distinctly lower in group R than those in group C (P < 0.01). The abnormal rate of motor neuron was significantly higher in group C during reperfusion than that in group R (P < 0.01). It has been shown that the intra-aortic REM-PCL infusion can alleviate SCIRI by inhibiting inflammatory response and improving mitochondrial anti-oxidation capacity.

ObjectiveTo study the feasibility of using propofol and remifentanil for tracheal intubation in patients who are awake, and investigate the influence of tracheal intubation on such vital signs as blood pressure and heart rates. MethodsEighty ASA I-Ⅱ patients who underwent general anesthesia in our hospital between December 2012 and April 2013 were randomly divided into two groups. Patients in group A received fentanyl-propofol, while patients in group B received remifentanyl-propofol-lidocaine. There was no significant difference between the two groups in gender, age, and body weight (P>0.05). Conventional intubation induction method was used for group A:0.05-0.10 mg/kg midazolam, 4 μg/kg fentanyl, 1.0-1.5 mg/kg propofol, and 0.6-0.9 mg/kg atracurium were given and tracheal intubation was performed after muscle relaxation. Group B patients were treated with remifentanyl propofol-lidocaine compound liquid slow intravenous injection, and compound cricothyroid membrane puncture method before endotracheal intubation. We observed the two groups of patients for vital signs before and after induction, and choking cough reactions. ResultsPatients in both the two groups were all able to complete tracheal intubation. Circulation change and incidence of tachycardia in patients of group A were significantly higher than those in group B (P<0.05). The rates of bradycardia, hypoxemia, and choking cough response were low in both groups with no statistically significant difference (P>0.05). ConclusionRemifentanyl propofol-lidocaine compound liquid can be safely used for implementation of endotracheal intubation in patients who are awake, and the hemodynamic stability can be maintained.
Objective To systematically review the clinical effectiveness and safety of sufentanil-propofol versus remifentanil-propofol during total intravenous anesthesia for neurosurgery. Methods Databases including The Cochrane Library (Issue 3, 2013), the database of the Cochrane Anesthesia Group, MEDLINE, EMbase, PubMed, Ovid, Springer, CNKI, VIP and WanFang Data were electronically searched from inception to May 2013 for the randomized controlled trials (RCTs) of sufentanil-propofol versus remifentanil-propofol during total intravenous anesthesia for neurosurgery. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the quality of included studies. Then, meta-analysis was performed using RevMan 5.1 software. Results Thirteen trials involving 647 patients were finally included. The results of meta-analysis showed that: a) for hemodynamic changes, MAP decreased in the remifentanil-propofol group after induction and decreased 5 minutes after intubation, but no significant difference was found between the two groups; the two groups were alike in MAP changes during craniotomy and extubation, and in HR changes after induction, 5 minutes after intubation, during craniotomy and extubation, with no significant difference. b) The result of intra-operative wake-up test showed that, there was no significant difference in the sedative effect and the time of awaking between the two groups. c) For emergence time and extubation time, compared with the sufentanil-propofol group, emergence time and extubation time were significantly shorter than those in the remifentanil-propofol group. d) For side effects, there was no significant difference in side effects (such as post-operative nausea, vomiting, respiratory depression, restlessness, chills and hypotension) between the two groups. And e) for post-operative pain, compared with the remifentanil-propofol group, post-operative 1-h and 2-h VAS were lower and the number of who need additional analgesic drugs within 24 h after operation was less in the sufentanil-propofol group, with significant differences. Both groups used the similar dosage of propofol with no significant difference. Conclusion Compared with the remifentanil-propofol group, hemodynamics changes in the sufentanil-propofol group is steadier after induction and during intubation. Patients in the sufentanil-propofol group are better in postoperative awakening quality. But they are alike in the incidence of side effects and propofol dosage.

Methods A total of 60 patients aged from 18 to 65 years, admitted from January to March 2009 and scheduled to undergo elective CO2-LELM under general anesthesia for treatment of vocal cord polyp were randomly assigned to a propofol group, an esmolol group, and a remifentanil group. Anesthesia was induced with midazolam (0.015-0.02 mg/kg), fentanyl (1 μg/kg), and propofol (1 mg/kg). After the patients became unconscious, succinylcholine (1 mg/kg) was given one minute later. Then the patients in the three groups received propofol (2 mg/kg), esmolol (1 mg/kg), and remifentanil (1 μg/kg), respectively. Intubation was performed 30 secconds later. Heart rate (HR) and systolic blood pressure (SBP) were measured noninvasively before general anesthesia induction (baseline, Tb), just before intubation(Ti), and one, three, and five minutes after intubation (T1, T3, T5). Results The demographic data including age, sex and body weight were comparable in the three groups. Tracheal intubation caused significant increases in SBP and HR in all groups compared with Ti (Plt;0.05). After intubation, SBP in the propofol group and the esmolol group were significantly higher than that in remifentanil group (Plt;0.05), and HR in the propofol group was significantly higher than that in the remifentanil group (Plt;0.05). Conclusion In patients with CO2-LELM, remifentanil (1 μg/kg) administrated 30 seconds before intubation is maximal effective compared with propofol (2 mg/kg) or esmolol (1 mg/kg) in attenuating the hemodynamic responses to oraltracheal intubation.
目的:观察等效剂量瑞芬太尼和芬太尼诱导气管插管对小儿血流动力学的影响。方法:40例择期行全麻患儿随机分为瑞芬太尼组和芬太尼组,麻醉诱导使用咪唑安定0.15mg/kg、丙泊酚2.5mg/kg、芬太尼2.5μg/kg或瑞芬太尼2μg/kg和维库溴铵0.1mg/kg。分别于麻醉诱导前(T0)、诱导后2min(T1)、插管后1、2min(T2、T3)记录心率、收缩压和舒张压。结果:两组诱导前血流动力学指标相似。与T0时比较,两组患儿T1时收缩压、舒张压均降低(Plt;0.05或Plt;0.01),心率均减慢(Plt;0.05或Plt;0.01);瑞芬太尼组T2.T3时收缩压、舒张压降低(Plt;0.05或Plt;0.01),心率减慢(Plt;0.05);芬太尼组T2、T3时收缩压、舒张压升高(Plt;0.05),心率增快(Plt;0.05)。与芬太尼组比较,瑞芬太尼组T1、T2和T3时收缩压、舒张压均降低(Plt;0.05),心率减慢(Plt;0.05)。结论:瑞芬太尼比等效剂量芬太尼能更好地抑制小儿全麻诱导气管插管时的心血管反应。
