【摘要】 目的 觀察依托咪酯乳劑復合舒芬太尼用于全麻下喉罩置入的血流動力學變化。 方法 選擇2009年4月-2010年2月間，46例需全麻手術、適合使用喉罩，美國麻醉醫師協會（ASA）Ⅰ～Ⅱ級，年齡18～60歲的患者，隨機分為兩組:依托咪酯乳劑組（E組）23 例，靜脈推注咪達唑侖0.05 mg/kg，依托咪酯乳劑0.3 mg/kg；依托咪酯乳劑+舒芬太尼組（ES組）23 例，靜脈推注咪達唑侖0.05 mg/kg，依托咪酯乳劑0.15 mg/kg，加舒芬太尼0.5 mg/kg，誘導后置入喉罩，記錄患者誘導前、用藥后1 min、喉罩置入后1 min的心率（HR）、平均動脈壓（MAP）以及評估喉罩置入條件的6項指標（張口困難分級、置入喉罩困難分級、舌咽反射、干咳干嘔反射、肢動反應及喉痙攣分級），同時記錄呼吸暫停時間。 結果 ES組能提供更好的喉罩置入條件，且能減少舌咽反射和肢體反應， 更能保證喉罩置入時血流動力學的穩定。 結論 依托咪酯乳劑復合舒芬太尼能為全麻喉罩置入時提供更好的條件，且能保證更好的血流動力學穩定。【Abstract】 Objective To investigate the hemodynamics changes when etomidate combined with sufentanil was applied for laryngeal mask airway insertion under the general anaesthesia. Methods From April 2009 to February 2010, 46 patients requiring general anesthesia using laryngeal mask airway (LMA) (American Society of Anesthesiologists (ASA)Ⅰ-Ⅱ) aged 18-60 were randomly divided into two groups: 23 in etomidate emulsion group (group E) underwent the intravenous injection with midazolm (0.3 mg/kg) and etomidate (0.05 mg/kg); 23 in etomidate emulsion + sufentanil group (group ES) underwent the intravenous injection with etomidate (0.15 mg/kg), midazolm (0.05 mg/kg), and sufentanil 0.5 mg/kg. The patients were evaluated by six indexes of LMA insertion (mouth opening, swallowing reflex, cough reflex,vomiting reflex, body motion, and laryngospasm classification). After the anesthesia induction, LMA was inserted. The blood pressure (BP), heart rate (HR), and mean arterial pressure (MAP) were recorded before anesthesia induction one minute after the injection and one minute after LMA insertion. Meanwhile, the apnea time was recorded. Results Compared with group E, group ES offered better anesthesia for LMA insertion, less swallowing reflex and body motion, and more stable haemodynamics. Conclusion Etomidate combined with sufentanil provides good condition for LMA insertion under the general anaesthesia with steady haemodynamics.
【摘要】 目的 比較喉罩全麻與氣管插管全麻兩種麻醉方法在小兒側臥位短小手術中的優缺點。 方法 2009年6月-2010年2月，將40例擇期行側臥位短小手術兒患，隨機分為喉罩全麻（L）組與氣管插管全麻（T）組，每組各20例。觀察患兒術中心率（HR）、平均動脈壓（MAP）、脈搏血氧飽和度（SpO2）、氣道峰壓（Pmax），惡心嘔吐、術后躁動等圍術期不良反應。 結果 T組插管后及拔管后即刻HR、MAP均高于L組患兒（Plt;0.05）；SpO2、Pmax在兩組之間比較差異無統計學意義（Pgt;0.05），T組患兒術后躁動發生率明顯高于L組（Plt;0.05）。 結論 喉罩可以安全、有效地用于小兒側臥位短小手術麻醉，且操作簡便，插管期和拔管期心血管應激反應輕，術后躁動發生率低。【Abstract】 Objective To compare the safety and efficacy of laryngeal mask airway (LMA) and tracheal tube in lateral general anesthetic operation on children. Methods From June 2009 to February 2010, 40 children scheduled to undergo general anesthesia for minor surgical procedures in lateral position were randomly divided into the laryngeal mask airway group (group L) and the tracheal tube group (group T) with 20 in each. Heart rate (HR), mean arterial pressure (MAP), pulse oxygen saturation (SpO2), top airway pressure (Pmax) of the patients were observed. In addition, side effects such as nausea, vomiting, and emergence agitation were also recorded. Results HR and MAP of patients in group T were significantly higher than those of patients in group L after intubation and after extubation (Plt;0.05). There was no difference in Pmax and SpO2 between the two groups (Pgt;0.05). The incidence of emergence agitation in group T was significantly higher than that in group L. Conclusions LMA intubation can provide the same safe and effective ventilation as tracheal intubation for children undergoing lateral general anesthetic operation. LMA is superior to tracheal intubation in insertion response, and the incidence of emergence agitation is lower.
