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.
Objective To investigate change of bispectral index(BIS) and hemodynamic index during induction and orotracheal intubation of sevoflurane anesthesia. Methods This study was a prospective before-after study in the same patients. A total of 30 ASA physical status I and II adult patients without airway abnormalities were enrolled to receive inhalation induction of anesthesia with 8% sevoflurane. Mean arterial pressure(MAP),heart rate(HR) and BIS were recorded before anesthesia(T1),when patients loss of consciousness(T2), before intubation (T3),at 1 min(T4) and 3 min(T5) after intubation. Results BIS at T1-T5 were 96.8±1.7,70.4±8.8,39.2±8.4,43.6±12.9 and 41.6±9.3 respectively, the measurements at T2-T5 were all markedly lower than at T1(Plt;0.05). HR at T3-T5 were all markedly higher than at T1(Plt;0.05). MAP at T2 and T3 were markedly lower than at T1, but at T4 was higher than at T1(Plt;0.05), and recovered to the level at T1 at T5(Pgt;0.05).BIS,HR and MAP at T4 were all significantly higher than T3(Plt;0.05). Conclusion Anesthesia induction with sevoflurane and small dose of succinylchoiline we used can provide adequate depth of general anesthesia,but can not prevent cardiovascular adverse reactions to intubation.
目的:觀察、比較七氟醚吸入麻醉與全憑靜脈麻醉在小兒先天性心臟病手術中的應用。方法: 40例擇期行先天性心臟病房室缺矯治術患兒,隨機分為七氟醚組和全憑靜脈麻醉組(TIVA組),每組各20例。七氟醚組患兒以七氟醚吸入誘導,復合小劑量芬太尼、咪達唑侖、維庫溴銨,麻醉維持為七氟醚吸入+芬太尼、維庫溴銨;靜脈組患兒肌注氯胺酮后,以芬太尼、咪達唑侖、維庫溴銨誘導,維持使用丙泊酚持續泵入+芬太尼、維庫溴銨。比較兩組術中各時點血流動力學變化、手術麻醉時間與芬太尼、維庫溴銨用量、術后呼吸支持時間、清醒時間、拔管時間,比較兩組不良反應發生情況。結果: 兩組患兒均維持比較穩定的血流動力學狀態。七氟醚組芬太尼與維庫溴銨用量明顯低于TIVA組,呼吸支持時間、清醒時間、拔管時間明顯低于TIVA組。七氟醚組2例術后發生躁動,3例發生惡心,稍高于TIVA組。結論: 七氟醚應用于小兒先心房室缺矯治術,可提供穩定的血流動力學狀態,并降低芬太尼與肌松劑用量,實現術后早拔管、改善患者預后、降低醫療費用。
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.
目的 研究七氟醚誘導氣管插管減輕短期內行兩次手術的腦性癱瘓患兒術前焦慮的效果。 方法 2009年12月－2011年7月選擇需要短期內行兩次全身麻醉（全麻）手術的痙攣性腦性癱瘓患兒60例，美國麻醉醫師協會（ASA）Ⅰ～Ⅱ級。隨機分為A組常規麻醉誘導氣管插管（30例）和B組七氟醚誘導氣管插管（30例）；分別在一期及二期手術術前訪視時（M1、M3）、入手術室時（M2、M4）對兩組患兒進行改良耶魯圍術期焦慮量表評估；并分別在一期及二期手術麻醉誘導期（N1、N2）對兩組患兒進行誘導期合作度量表的標準評定。 結果 同組一期、二期手術比較，A組患兒二期手術術前焦慮更明顯（P＜0.05），二期入手術室時焦慮更明顯（P＜0.05），二期手術合作度更差（P＜0.05）；B組患兒兩次手術術前焦慮無明顯變化（P＞0.05），一期入手術室時焦慮明顯（P＜0.05），一期手術合作度較差（P＜0.05）。兩組之間，一期手術兩組患兒焦慮情況無明顯區別（P＞0.05），二期手術A組比B組的患兒焦慮更明顯（P＜0.05），兩次手術B組都比A組的患兒合作度更好（P＜0.05）。 結論 七氟醚麻醉誘導氣管插管能夠有效減輕短期內需要進行兩次手術的痙攣性腦性癱瘓患兒的術前焦慮，提高患兒二期手術的合作度，提供良好的手術麻醉條件，保證患兒的圍術期安全。
摘要:目的:分析與比較七氟醚吸入麻醉和丙泊酚靜脈復合麻醉應用于三聚氰胺致嬰幼兒輸尿管結石手術的麻醉效果。方法:60例輸尿管結石患兒隨機分為七氟醚(Sev)組(n=30)和丙泊酚(Pro)組(n=30)。觀察并記錄誘導時間、氣管內插管時間、蘇醒時間、拔除氣管插管時間、PACU滯留時間。記錄麻醉誘導和蘇醒期的不良反應。另外記錄兩組病人誘導前、插管前、插管后3 min、5 min、15 min、30 min時點的血壓、心率、脈搏血氧飽和度(SPO2)。結果:七氟醚組誘導時間(63.2±6.9)s長于丙泊酚組(38.2±12.7)s,七氟醚組拔除氣管插管時間(11.9±4.7)min短于丙泊酚組(15.6±8.2)min,兩組相比有統計學意義(Plt;0.05)。七氟醚組躁動發生率53.3%顯著高于丙泊酚組13.3%(Plt;0.01)。七氟醚組在插管前、插管后各時點的血壓、心率與誘導前相比,差異無統計學意義(Pgt;0.05),丙泊酚組插管前、插管后3 min、5 min與誘導前相比血壓、心率顯著降低(Plt;0.05),與同時間點七氟醚組相比血壓顯著降低(Plt;0.05)。結論:兩種麻醉方法均可安全有效用于嬰幼兒輸尿管結石手術,七氟醚組血流動力學更平穩,但躁動發生率較高。Abstract: Objective: To analyze and compare sevoflurane with propofol for anesthesia in infants with Melamineinduced ureteral stone surgery. 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.
