Objective To investigate clinical application and safety evaluation of sedative demulcent anesthesia in therapeutic endoscopic retrograde cholangiopancreatography (ERCP).Methods Totally 1660 patients underwent ERCP at the First Hospital of Lanzhou University were prospectively divided into two groups: venous sedative demulcent group (n=800, using sufentanil and midazolam and propofol continuing infusion) and conventional sedative demulcent group (n=860, using common medicine). The heart rate (HR), respiration (R), blood pressure (BP) and peripheral oxygen saturation (SpO2) of pre-anesthesia, post-anesthesia, during operation and after analepsia in every group were detected. The narcotism was evaluated by Ramsaymin grading method and the related adverse reactions such as cough, restlessness, harmful memory, and abdominal pain after operation were recorded. Results Compared with conventional sedative demulcent group, vital signs of patients in venous sedative demulcent group were more stable. For postoperative adverse reactions, abdominal pain, abdominal distension and nausea and vomiting were respectively 4.4%(35/800), 2.6%(21/800) and 3.6%(29/800) in venous sedative demulcent group, which were respectively higher of the incidence of 36.3%(312/860), 49.0%(421/860) and 53.0%(456/860) in conventional sedative demulcent group (P＜0.01). The postoperative satisfaction and adverse reactions recall between venous sedative demulcent group and conventional sedative demulcent group was respectively significant different (96.9% vs. 2.9%, 4.8% vs. 97.9%, P＜0.01). Conclusion Sufentanil and midazolam and propofol continuing infusion have good effect of sedative demulcent anesthesia, which can be widely used.
Objective To evaluate the association between anesthesia regimen (volatile or intravenous anesthetics) and postoperative infection in adult cardiac patients undergoing cardiac surgery. MethodsThe clinical data of 496 elective adults undergoing cardiac surgery under cardiopulmonary bypass from June 2019 to June 2020 in West China Hospital of Sichuan University were retrospectively analyzed, including 251 females and 245 males with an average age of 54.1±11.4 years. American Society of Anesthesiologists grade was Ⅰ-Ⅲ. There were 243 patients in a volatile group with sevoflurane or desflurane, and 253 patients in an intravenous anesthesia group with propofol. The primary outcome was the incidence of infection within 30 days after cardiac surgery, including pulmonary infection, surgical site infection, sepsis, and urinary tract infection. The secondary outcomes were duration of mechanical ventilation, incidence of reintubation, ICU stay, postoperative length of hospital stay and total hospitalization cost. Results A total of 155 (31.3%) patients developed postoperative infection within 30 days, with an incidence of 32.9% in the volatile group and 29.6% in the intravenous anesthesia group. There was no statistical difference in the incidence of infection (RR=1.111, 95%CI 0.855 to 1.442, P=0.431) or the secondary outcomes (P>0.05) between the two groups. Conclusion The anesthesia regimen (volatile or intravenous anesthetics) has no association with the risk of occurrence of postoperative infection in adult patients undergoing elective cardiac surgery with cardiopulmonary bypass.

ObjectiveTo evaluate the effects of sevoflurane and propofol on preoperative implicit and explicit memories in general anaesthesia patients of elective surgery. MethodsThe surgical inpatients in Sichuan Provincial People's Hospital were enrolled from December 2013 to May 2014, and were randomly divided into three groups (S, P, M). In Group S, anesthesia was induced and maintained with sevoflurane. In Group P, anesthesia was induced and maintained with propofol. Midazolam was not utilized throughout the whole anaesthesia for the above groups. Patients in Group S and Group P were given a list of test materials to remember and listen before the anesthesia. Within 12 to 36 hours after operation, memory was assessed, based on the Buchner's model applied on the process dissociation procedure (PDP) using a phrases task. The Group M was given the same test materials, and received test with the PDP in 12 to 36 hours before surgery. Value A and value R were used to represent the implicit memory score and the explicit memory score, respectively. ResultsA total of 150 patients were included, and 50 cases were included in each group. During testing, 2 cases were excluded, 3 cases were loss to follow-up, so finally 49 cases were included in the Group S, 47 cases in the Group P and 49 cases in the Group M. The results showed that there were significant differences in the implicit memory score (A) and the explicit memory score (R) among the three groups (all P values <0.05). The explicit memory score (R) of the Group M was higher than those of the Group P and Group S (all P values <0.05), the implicit memory score (A) in the Group M was higher than those of the Group S and Group P (all P values <0.05), and the implicit memory score (A) in the Group S was higher than that of the Group P (P<0.05). ConclusionPropofol and sevoflurane can decrease the score of explicit memory after anesthesia within 12 to 36 hours, and there are no significant differences in explicit memory between the two drugs. Both propofol and sevoflurane can decrease the score of implicit memory, but the influence of sevoflurane on the implicit memory is less than propofol within 12 to 36 hours.

Methods: Sixty infants who were to undergo Melamineinduced ureteral stone surgery were randomly divided into sevoflurane (Sev) group (n=30) and propofol (Pro) group (n=30). Observe and record the induction of anesthesia time, intubation time, awakening time, time to extubation, time to stay at PACU. Record adverse effects during induction of anesthesia and the awake period. In addition, recorded BP, HR, SPO2 of two groups before induction and intubation, after 3min、5min、15min、30min after intubation. Results: Induction time ［（63.2 ± 6.9） s］ in sevoflurane group was longer than propofol group ［(38.2±12.7） s］,but extubation time ［（11.9 ± 4.7） min］ was shorter than propofol group ［(15.6 ± 8.2） min］, there was significantly different between two groups (Plt;0.05). The incidence of restlessness in sevoflurane group 53.3% was significantly higher than propofol group 13.3% (Plt;001). In sevoflurane group the BP, HR before intubation compare with after intubation has no significant difference (Pgt;0.05). Compared with before induction,the BP, HR before induction, after intubation 3 min, 5 min, decreased significantly (Plt;0.05) in propofol group.when compared the same point with sevoflurane group, blood pressure decreased significantly (Plt;0.05). Conclusion: Both propofol and sevoflurane can be used effectively and safely for anesthesia of ureteral calculi stone surgery in pediatric. The hemodynamics is more stable but restlessness is more common in sevoflurane group.
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.
