D).There was no difference in the SS scores among the groups.Mobility of nausea and vomiting was most frequently in each group but especially in the Group D.There was less adverse effect in Group A and B than in Group C and D.ConclusionFlurbiprofen axetil can be used for the PCA of MVD safely.It offers the preemptive analgesic effecanalgesia.There are less adverse effects than fentanyl or tramadol used only.

Objective To provide a simple, convenient, and safe anesthesia method for the establishment of a M1 segment of middle cerebral artery occlusion model in rhesus monkey or other large laboratory animals.Method Twenty male rhesus monkeys weighing 7-11 kg (ages 7-9 years) from Academy of Military Medical Sciences were used in this study.Sumianxin injection combined with 0.1 mg/kg ketamine was given before endotracheal intubation (ID:4.5-5.5#).The animals were then transported to an interventional operation room, where the intravenous access was established and a urinary catheter was inserted into the urinary bladder.Mechanical ventilation was used during the surgery, propofol was continuously injected in a speed of 2-4 mg/kg/h, and Sumianxin-ketamine could be given if necessary to maintain adequate anesthesia depth.The dose was adjusted according to vital signs of the rhesus such as body movements, physiological parameters, and demand of surgery.Brain MRI examination was performed before and after thrombolysis.Anesthetic injection was suspended and the animals were allowed to have a spontaneous breathing every time before the MRI text.Heart rates, temperature, non-invasive blood pressure, and SpO2 were monitored during the whole surgery.Blood samples were taken from the radial artery for blood gas analysis after anesthesia induction and during operation.Results All the 20 animals underwent the operation successfully, no animal had restlessness, respiratory depression, arrhythmia and other serious complications.At the end of the study, animals awake soon.Fifteen of them survived longer than 24 hours, only 5 died from serious cerebral hemorrhage and larger cerebral infarction.Conclusions General endotracheal anesthesia is safe for rhesus monkeys during such interventional operation and MRI examination.

Objective To discuss the treatment method and opportunity for patients with gallbladder stones and extrahepatic bile duct stones who failed endoscopic removal of common bile duct stones by endoscopic retrograde cholangiopancreaticography (ERCP). Methods 12 patients, with gallbladder stones and extrahepatic bile duct stones, failed endoscopic stone extraction (ESE), underwent emergency one-stage laparoscopic cholecystectomy (LC) and Laparoscopic common bile duct exploration (LCBDE). Results All of the patients were successfully completed LC +LCBDE and stones were completely removed. Hyperamylasemia occurred in 3 cases and there was no bile leakage, intestinal leakage, cholangitis, pancreatitis, biliary bleeding and other complications. Conclusions Emergency LCBDE has been shown to be a safe and effective salvage procedure for failed ESE.

Objective: To explore the intervention effect of improved nursing measures in the treatment of patients with dystonia with deep brain stimulation in MRI localization. Methods: Twenty patients with dystonia treated with deep brain stimulation from January 2013 to December 2015 were selected as the control group. Twenty patients with dystonia treated by deep brain stimulation surgery with improved nursing from January 2016 to December 2018 were in the experimental group. The primary success rate of MRI localization, examination time related indexes and incidence of adverse reactions after intravenous anesthesia were observed in the 2 groups. Results: The primary success rate of MRI localization in the experimental group (95.00%,19/20) was higher than that in the control group (55.00%,11/20), and the difference was statistically significant (χ²=8.533, P<0.01).The total examination time of the experimental group (33.60±8.27) min was significantly shorter than that of the control group (44.30±13.43) min, and the difference was statistically significant (t=-3.663, P<0.05).The incidence of total adverse reactions to MRI localization after intravenous anesthesia was lower in the experimental group (5%, 1/20) than in the control group (30%, 6/20), and the difference was statistically significant (χ² =4.329, P < 0.05). Conclusions Improved nursing measures can effectively improve the success rate of MRI stereotactic brain target location in patients with dystonia, providing a guarantee for accurate calculation of surgical targets, enabling the operation to achieve the best results, early detection of changes in vital signs during examination, and the close cooperation of the medical team is the guarantee for the smooth completion of MRI examination.
