Objective To systematically review the impacts of general anesthesia using sevoflurane versus propofol on the incidence of emergence agitation in pediatric patients. Methods Such databases as PubMed, EMbase, Web of Science, The Cochrane Library (Issue 4, 2012), CNKI, CBM, WanFang Data and VIP were electronically searched from inception to December 2012, for comprehensively collecting randomized controlled trials (RCTs) on the impacts of general anesthesia using sevoflurane versus propofol on the incidence of emergence agitation in pediatric patients. References of included studies were also retrieved. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.1 software. Results A total of 9 RCTs involving 692 children were included, of which, six were pooled in the meta-analysis. The results of meta-analysis showed that: a) after anesthesia induction using sevoflurane, intravenous propofol maintenance was associated with a lower incidence of emergence agitation compared with sevoflurane maintenance (RR=0.57, 95%CI 0.39 to 0.84, P=0.004); and b) patients anesthetized with total intravenous propofol had a lower incidence of emergence agitation compared with total inhalation of sevoflurane (RR=0.16, 95%CI 0.06 to 0.39, Plt;0.000 1). Conclusion The incidence of emergence agitation after general anesthesia using sevoflurane is higher than that using propofol. Due to the limited quantity and quality, the application of sevoflurane should be chosen based on full consideration into patients’ conditions in clinic.
【摘要】 目的 评价α2受体激动剂是否可以降低七氟烷引起的小儿术后躁动的发生率。 方法 通过检索Medline、荷兰医学文摘、Cochrane临床试验数据库、中国生物医学文献数据库和中国期刊网全文数据库等数据库，收集可乐定或右美托咪啶对七氟烷引起的小儿术后躁动的预防作用的随机对照试验（randomized controlled trial，RCT），提取资料和评估方法学质量，采用Cochrane协作网RevMan 5.0软件进行Meta分析。 结果 最终纳入11个RCT，其中104例患儿预防性使用右美托咪啶，268例患儿使用可乐定，365例患儿使用安慰剂。Meta分析显示，可乐定组小儿术后躁动发生率的比值比（OR）为0.31，95%CI为（0.15，0.61）（P=0.000 8）；右美托咪啶组小儿术后躁动发生率的OR为0.16，95%CI为（0.08，0.31）（Plt;0.000 01）。 结论 α2受体激动剂可以显著降低七氟烷引起的小儿术后躁动的发生率。【Abstract】 Objective To determine whether alpha2-adrenoceptor agonists can decrease emergence agitation (EA) in pediatric patients after sevoflurane anesthesia. Methods The Medline, Embase, Cochrane Library, CBM and CNKI were searched. All randomized controlled trials comparing clonidine or dexmedetomidine with other interventions in preventing emergence agitation after sevoflurane anesthesia were retrieved. Study selection and assessment, data collection and analyses were undertaken. Meta-analysis was done using the Cochrane Collaboration RevMan 5.0 software. Results Eleven articles reached our inclusion criteria and were included in the Meta-analysis. A total of 104 children treated with dexmedetomidine, 268 children treated with clonidine, and 365 children treated with placebo were evaluated for the incidence of emergence agitation. The pooled odds ratio for the clonidine subgroup was 0.31, with a 95% confidence interval of 0.15-0.61 (P=0.000 8). The pooled odds ratio for the dexmedetomidine subgroup was 0.16, with a 95% confidence interval of 0.08-0.31 (Plt;0.000 01). Conclusion Alpha2-adrenoceptor agonists can significantly decrease the incidence of emergence agitation in pediatric patients after sevoflurane anesthesia.
目的 探讨右美托咪定对小儿七氟烷吸入麻醉苏醒期躁动的影响。 方法 选择2011年3月－2012年1月美国麻醉医师协会分级Ⅰ～Ⅱ级、年龄2～8岁、择期行疝囊高位结扎术和隐睾下降固定术患儿40例，随机分为2组，右美托咪定组（A组）和对照组（B组），两组患儿在年龄、体重、手术种类无明显差异。两组患儿均采用面罩8%七氟烷吸入麻醉诱导，开放静脉，给予盐酸戊乙奎醚0.1 mg/kg、顺式阿曲库铵0.15 mg/kg，插入喉罩，麻醉维持根据血压、心率及脑电双频指数调节吸入麻醉药浓度。A组静脉给予1 μg/kg右美托咪定，B组给予同等容量的生理盐水。入室至手术结束时连续观察收缩压、舒张压、心率、血氧饱和度，记录清醒时间、拔除喉罩时间，记录苏醒期并发症的发生数。记录入麻醉恢复室即刻（0 min）、15、30、60、90 min患儿疼痛和躁动评分。 结果 两组患儿在手术时间、清醒时间以及拔除喉罩时间差异无统计学意义（P＞0.05），A组术后入恢复室0、15、30 min疼痛评分和躁动评分均低于B组（P＜0.05），两组患儿围术期均未出现低血压和心动过缓。 结论 右美托咪定用于小儿七氟烷吸入麻醉能够增强术后镇痛，减少苏醒期躁动。
Objective To explore the emergence agitation resulting from postoperative indwelling urethral catheters in patients of thoracic surgery. Methods In this prospective cohort study, we recruited 140 patients who were scheduled for thoracic surgery under general anesthesia in West China Hospital from January through April 2014. These patients were divided into two groups including a control group and a trial group with 70 patients in each group. The patients in the control group had indwelled urethral catheter routinely. The catheter removed after the surgery at operation room in the trial group. Intraoperative urinary volume, emergence agitation (EA) occurrence, postoperative urinary retention, and urethral irritation were recorded. Results There was no statistical difference in postoperative urinary retention rate between the control group and the trial group (1.43% vs. 2.86%, P=0.230). However, the urethral irritation rate in the control group was significantly higher than that in the trial group (12.86% vs. 0.00%, P=0.012) . And there was a statistical difference in adverse event rate (2.86% vs. 0.00%, P=0.039) between the two groups. There was a significantly higher incidence of urethral irritation in male patients (20.51%, 8/39) than female patients (3.23%, 1/31, P=0.033).The rate of EA in the control group was significantly higher than that in the trial group (28.57% vs. 12.86%, P=0.010). There was a significantly higher EA rate in the patients who had urethral irritation by postoperative indwelling catheters compared with those without indwelling catheters (45.00% vs. 12.86%, P=0.043). Conclusion This study suggests that postoperative EA is a result from urethral irritation than local pain, and the EA rate can be decreased by removal of catheter before anaesthetic recovery.
ObjectiveTo determine the effects of the management mode participated by doctors, nurses and patients on the safety of medical tubes for restlessness patients in the Neurosurgery Intensive Care Unit (NICU). MethodsA total of 133 restlessness patients treated between May 17 and November 22, 2013 were included in the study as control group, who were admitted to the NICU before application of the management mode participated by doctors, nurses and patients; another 119 restlessness patients treated between May 17 and November 22, 2014 were included in the study as research group, who were admitted to the NICU after application of the management mode participated by doctors, nurses and patients. Then we compared the accidental extubation situation between the two groups. ResultsThe accidental extubation rate of all kinds of medical tubes in the research group was lower than that in the control group, among which the extubation rate of urethral catheter (0.67% vs. 4.32%), gastric tube (2.26% vs. 10.14%), trachea cannula (1.08% vs. 7.84%), and arterial cannulation pipeline (1.12% vs. 6.93%) was significantly different between the two groups (P<0.05). ConclusionThe management mode participated by doctors, nurses and patients can effectively reduce the accidental extubation rate of medical tubes for restlessness patients, prevent the occurrence of adverse events and ensure the treatment and nursing safety in the NICU.
Objective To assess the correlation between bispectral index (BIS) and richmond agitation sedation scale (RASS) and sedation-agitation scale (SAS) through the spearman correlation coefficient by systematic review. Methods Databases including PubMed, EMbase, Web of Science, The Cochrane Library (Issue 7, 2016), CNKI, VIP, WanFang Data and CBM were searched from inception to July 2016 to collect literature on the correlation between BIS and RASS and SAS. The studies were screened according to the inclusion and exclusion criteria. After extracting data and assessing the quality of the included studies, meta-analysis was conducted using Comprehensive Meta Analysis 3.0 software. Results A total of 12 studies involving 397 patients were included. BIS was positively correlated with RASS score and SAS, and the summary correlation coefficient was 0.742 with 95% CI 0.678 to 0.795 and 0.605 with 95% CI 0.517 to 0.681, respectively. Conclusion BIS has a good correlation with RASS and SAS, which will provide more options for assessing sedation of patients with mechanical ventilation in ICU.
