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.
