Methods A total of 480 patients at ASA grade Ⅰ-Ⅲ to be operated in the lower abdomen, perineum and lower limbs under CSEA from March to December 2009 were randomly divided into four groups: midazolam group (M group), propofol group Ⅰ (PA group), propofol group Ⅱ (PB group), and propofol group Ⅲ (PC group), with 120 patients in each group. All four groups of patients underwent CSEA at L2-3 or L3-4 and accepted pinal injection of 12-15 mg of 0.2% hypobaric bupivacaine. After the anesthetic plane was confirmed, patients in M group accepted 0.04-0.06 mg/kg of midazolam; patients in PA group accepted propofol at a loading dose of 0.50 mg/kg followed by continuous infusion at a dose of 2.00 mg/(kg•h); patients in PB group accepted propofol at a loading dose of 0.75 mg/kg followed by continuous infusion at a dose of 3.00 mg/(kg•h); patients in PC group accepted propofol at a loading dose of 1.00 mg/kg followed by continuous infusion at a dose of 3.75 mg/(kg•h). The change of hemodynamics including the mean arterial pressure (MAP) and the heart rate (HR), bispectral index (BIS) values, sedation scores, memory of pictures seen during operation and adverse effects before drug administration (T0), at minute 1 (T1), 3 (T2), 5 (T3), 10 (T4), 30 (T5) and 60 (T6) after drug administration were observed. Results MAP and HR decreased in all the four groups after administration of sedatives, but the changes of measured values were within normal ranges. BIS value and the Observer’s Assessment of Alertness and Sedation (OAA/S) scale decreased in all groups at T3, compared with those at T0 (Plt;0.05). Compared with the other 3 groups, BIS valueand OAA/S scale were significantly lower in PC group at T4, T5 and T6 (Plt;0.05), and the satisfaction rate of sedation and amnesia was much higher. No serious glossocoma, apnea and SpO2 below 90% was observed in all the four groups. Conclusion During the surgery of lower abdomen and lower limbs, application of CSEA combined with propofol at a loading dose of 1.00 mg/kg followed by continuous infusion at a dose of 3.75 mg/(kg•h) can achieve a good sedative effect, with little side effect.
Objective To explore the effects of propofol and thiopental sodium injection on convulsive seizure in electro-convulsive therapy(ECT) and to provide evidence to help the selection of intravenous anaesthetics in improved ECT. Methods Total of 111 patients who received ECT in the 3rd Pepole’s Hospital of Panzhihua from July to December 2005 were divided into a thiopental sodium group (n =62) and a propofol group (n =49). These patients received intravenous anaesthesia with suxamethonium plus thiopental sodium or propofol for the implementation of ECT, respectively. The status of convulsive seizure was compared between the two groups. Results There were no significant differences between the two groups in terms of main demographic data, disease category and ECT parameters (Pgt;0.05). Motor seizure and electricity discharge lasted significantly longer in the propofol group than in the thiopental sodium group (Plt;0.01). Conclusion Thiopental sodium can increase the excitation threshold of brain cortical neurons and decrease the level of convulsive seizure induced by ECT. Propofol may decrease the excitation threshold, and increase the level of convulsive seizure under the same ECT parameters, but may have the potential to induce epileptic seizure.
【摘要】 目的 观察丙泊酚在重症监护室（ICU） 外科术后对患者的镇静效果及作用。 方法 2006年7月-2008年7月，对行外科手术后在ICU观察室采用丙泊酚镇静的45例患者的镇静效果、停药苏醒时间及给药前后呼吸、循环参数的变化进行观察，并与治疗前进行比较。 结果 丙泊酚镇静起效快，镇静治疗后大多数患者开始血压有所下降（Plt;0.05）但不久恢复正常，所有患者心率、呼吸频率、血氧饱和度无明显变化（Pgt;0.05），停药后苏醒快。 结论 丙泊酚是外科术后患者较理想的镇静剂，但应根据患者情况调整给药速度、剂量及时间。 【Abstract】 Objective To observe the sedative effect of propofol on the patients after surgical operations in intensive care unit (ICU). Methods Forty-five patients underwent the injection with propofol after surgical operations in ICU from July 2006 to July 2008. The sedative efficacy, recovery time after the propofol administration, and changes of respiratory, circulate parameter before and after medication were observed, which were compared with those before the treatment. Results The sedative reactive time of propofol was short. Most of the patients had decreased blood pressure after injection with propofol (Plt;0.05) but recovered soon. The heart rate, respiratory rate, and pulse oxygen saturation did not significantly changed (Pgt;0.05). The recovery time was short after propofol administration was stopped. Conclusion Propofol is an effective sedative for the patients after surgical operations in ICU, but the medicated speed, amount and time according to state of the patients should be adjusted.
ObjectiveTo determine whether there was a clinical relevant association between anesthetic regimen (propofol or inhalational anesthetics) and the occurrence of postoperative delirium (POD) in patients undergoing cardiac surgery.MethodsThis retrospective study was conducted on patients with elective cardiac surgery under cardiopulmonary bypass (CPB) at West China Hospital of Sichuan University between October 2018 and March 2019. The patients were divided into a propofol group or an inhalational anesthetics group according to anesthetic regimen (including CPB). The primary outcome was the occurrence of POD during first 3 days after surgery. Logistic regression analysis was used to determine the relationship between anesthetic regimen and the occurrence of POD.ResultsA total of 197 patients who met the inclusion criteria were included, with an average age of 53 years, and 51.8% (102/197) were females. POD occurred in 21.3% (42/197) patients. The incidence of POD was 21.4% in the propofol group and 21.2% in the inhalational anesthetics group; there was no significant difference between the two groups (RR=1.01, 95%CI 0.51-2.00, P=0.970). Logistic regression analysis did not find that anesthetic regimen was a risk factor for delirium after cardiac surgery after adjusting risk factors (OR=1.05, 95%CI 0.48-2.32, P=0.900).ConclusionAnesthetic regimen (propofol or inhalational anesthetics) is not associated with an increased risk for POD in adult patients undergoing elective cardiac surgery under CPB.

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.
Objective To systematically assess the effectiveness and safety of 5-HT3 receptor antagonists in preventing propofol injection induced pain. Methods Databases including PubMed, EMbase, The Cochrane Library (Issue 1, 2012), CNKI, CBM, VIP and WanFang Data were searched from their inception to September, 2012 to collect the randomized controlled trials (RCTs) about 5-HT3 receptor antagonists in preventing propofol injection induced pain. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the quality of methodology. Then meta-analysis was performed using RevMan 5.2 software. Results A total of 15 RCTs involving 1 413 patients were included. The results of meta-analysis showed that: a) the incidence of propofol injection induced pain in the 5-HT3 group was obviously lower than the control group (RR=0.14, 95%CI 0.09 to 0.21, Plt;0.000 01); b) as to the severity of pain, there was no statistical difference between the two groups (RR=0.84, 95%CI 0.56 to 1.26, P=0.39); the 5-HT3 group was obviously lower that the control group in the incidence of both moderate pain (RR=0.25, 95%CI 0.19 to 0.34, Plt;0.000 01) and severe pain (RR=0.16, 95%CI 0.10 to 0.24, Plt;0.000 01); and c) as to the incidence of postoperative adverse reaction: the 5-HT3 group was obviously lower that the control group in the incidence of nausea and vomiting (RR=0.19, 95%CI 0.11 to 0.34, Plt;0.000 01) and shivering (RR=0.20, 95%CI 0.12 to 0.33, Plt;0.000 01) as well. Conclusion 5-HT3 receptor antagonists can effectively prevent the propofol injection induced pain, alleviate its severity, and reduce the postoperative adverse reactions. For the quantity and quality limitation of the included studies, this conclusion still needs to be further proved by performing more high quality studies.
