Supreme喉罩；全身麻醉；氣管插管

聲門上通氣裝置作為一種氣管插管選項(xiàng)越來越多地用于各種復(fù)雜的擇期手術(shù)［1］。Supreme喉罩(Laryngeal mask airway supreme, LMAS)是一種最新引進(jìn)的一次性聲門上通氣裝置, 具有Pro-Seal喉罩和插管型喉罩二者的共同特點(diǎn)［2］。2009年12月～2013年12月, 本院成功應(yīng)用LMAS全身麻醉患者9000余例。作者對(duì)LMAS全身麻醉和傳統(tǒng)的氣管插管全身麻醉用于腹腔鏡、乳腺外科等手術(shù)的效果進(jìn)行了前瞻性隨機(jī)對(duì)比研究, 現(xiàn)報(bào)告如下。

2.3 Ⅰ組、Ⅱ組第一次插罩/管成功率分別為92.68%(380例/410例)和90.73%(372例/410例), 差異無統(tǒng)計(jì)學(xué)意義(P＞0.05)；Ⅰ組28例氣囊充氣后IPPV時(shí)口咽部有異常氣流聲、PETCO2波形異?；騊peak>25 cm H2O等情況, 經(jīng)調(diào)整第二次重新置入LMAS后正常, 2例反復(fù)調(diào)整無效改氣管插管；Ⅱ組36例2次氣管插管成功, 2例3次以上插管失敗改用插管型喉罩氣管插管成功。

3 討論

LMAS是一種依照解剖學(xué)彎曲設(shè)計(jì)的一次性的新型聲門上通氣裝置, 它有第二個(gè)管道用于插入胃管［4］。由于喉罩置入口咽腔未接觸患者聲帶和氣管, 對(duì)聲門氣管無刺激, 循環(huán)相對(duì)穩(wěn)定。本研究Ⅰ組置入喉罩后和拔除喉罩時(shí)HR、BP與基礎(chǔ)值比較變化不大, 蘇醒迅速, 故合并高血壓、ECG異常老年患者手術(shù)可首選喉罩全身麻醉, 避免氣管插管操作對(duì)循環(huán)的明顯影響, 降低心血管意外的風(fēng)險(xiǎn)。而氣管插管或拔管須經(jīng)過聲門, 可刺激呼吸道, 對(duì)聲帶與氣管造成機(jī)械損傷,使機(jī)體心血管應(yīng)激反應(yīng)增強(qiáng), HR增快、BP升高, 心肌耗氧量增加, 心臟負(fù)荷加重, 增加了麻醉意外的風(fēng)險(xiǎn)。

腹腔鏡手術(shù)CO2氣腹時(shí)腹壓增加, 膈肌上移, 返流誤吸的風(fēng)險(xiǎn)加大； LMAS是一種帶有引流胃內(nèi)容物管腔的一次性聲門上通氣裝置, 在置入喉罩及麻醉期間可即刻評(píng)估喉罩的位置是否正確［5］, 經(jīng)引流管腔插入吸痰管吸引胃內(nèi)容物, 有效防范胃液返流誤吸, 保護(hù)氣道, 降低胃脹氣, 為腹腔鏡手術(shù)提供良好視野［3］；LMAS充氣囊經(jīng)過改進(jìn)能夠提供可靠的氣道和良好的氣道密封性［6］, 減少正壓通氣時(shí)喉罩氣囊周圍的漏氣, 降低胃脹氣發(fā)生率。Ⅰ組腹腔鏡手術(shù)患者通氣效果與Ⅱ組相同, 無一例發(fā)生返流誤吸及胃脹氣, 進(jìn)一步說明LMAS可適合替代氣管插管用于擇期腹腔鏡手術(shù)的患者［7］, LMAS全身麻醉可滿足此類手術(shù)麻醉的要求。

LMAS經(jīng)過塑型處理, 更符合人體咽喉部解剖生理曲線,無論操作者是否有經(jīng)驗(yàn), 均可快速而容易地置入喉罩, 經(jīng)過幾個(gè)簡(jiǎn)單測(cè)試即能明確喉罩對(duì)位是否準(zhǔn)確；Ⅰ組第一次置入喉罩成功率達(dá)92.68%, 說明操作簡(jiǎn)單, 容易掌握, 成功率高；Ⅰ組咽喉痛明顯少于Ⅱ組, 顯示LMAS容易插入, 咽喉部舒適度優(yōu)越, 氣道發(fā)病率低［8］。Ⅰ組28例經(jīng)調(diào)整第二次重新置入LMAS后正常, 2例女性患者反復(fù)調(diào)整喉罩不佳改為氣管插管, 雖然按體重選擇相應(yīng)型號(hào)的喉罩, 但發(fā)生喉罩型號(hào)偏大情形, 需重新置入喉罩完成麻醉通氣。女性患者如何選擇(按體重、身高及口咽腔大小)合適型號(hào)的LMAS還有待進(jìn)一步研究。

綜上所述, LMAS用于全身麻醉與氣管插管的通氣效果相同, 具有血流動(dòng)力學(xué)穩(wěn)定、操作簡(jiǎn)單、不良反應(yīng)少等優(yōu)點(diǎn),可完全替代氣管插管, 安全有效地用于婦科、乳腺外科手術(shù)和部分肝膽外科、骨科、腫瘤外科、普外科、燒傷科的手術(shù),尤其適用于合并有高血壓、ECG異常的老年患者。但用于頭頸手術(shù)、開胸手術(shù)、俯臥位、側(cè)臥位、嚴(yán)重肥胖、手術(shù)時(shí)間冗長的手術(shù)存在一定局限性及氣道管理的風(fēng)險(xiǎn)。

Objective To evaluate the application value and status of laryngeal mask airway Supreme (LMAS) in patients undergoing general anesthesia.Methods A total of 820 cases with ASA grade I～Ⅲundergoing general anesthesia were randomly divided into two groups.GroupⅠ (n=410)

general anesthesia through LMAS and groupⅡ(n=410) received general anesthesia through endotracheal tube (ETT).The changes of HR、SBP、DBP were recorded as the basal values, during intubation and extubation.Operation time, anesthesia time and patients recovery time were observed; The success rate of the first attempt insertion, the peak inspiratory airway pressure (Ppeak), end-tidal carbon dioxide (PETCO2) and the effectiveness of ventilation were recorded during operation.The adverse reactions of anesthesia were recorded, such as countercurrent, bucking, aspiration, body movement, and postoperative pharyngalgia.Results HR, SBP, DBP of group Ⅱ were significantly higher than the basal value during intubation and extubation, and the difference was statistically significant (P<0.05).HR、SBP、DBP of group I were significantly lower than those in groupⅡ, and the difference had statistical significance (P<0.01).The patients recovery times were significantly shorter in group I than that in groupⅡ, and the difference had statistical significance (P<0.05).The success rates of the first attempt insertion were 92.68% (LMAS) and 90.73% (ETT), and the differences between Ppeak, PETCO2and the effectiveness of ventilation were not statistically significant in the two groups (P>0.05).No bucking, body movement, countercurrent and aspiration appeared in the two groups during intubation, and there was no significant difference (P>0.05).The patients’bucking, body movement, postoperative pharyngalgia in group I were significantly lower than those in groupⅡ, and the differences were statistically significant (P<0.05).Conclusion LMAS in general anesthesia has stability on the hemodynamic change, and can reduce the adverse effects of cardiovascular system, which can insert easy with fewer complications.It can be a substitute for tracheal intubation and safely and effectively used for laparoscope and breast surgery, especially for old patients with hypertension and electrocardiograph (ECG) abnormality．
