【摘要】:目的:探討可實(shí)施表面麻醉的氣管插管的制作和臨床應(yīng)用。制作方法:我們?cè)黾恿艘桓蚵曢T下注藥的導(dǎo)管,與氣囊的注氣管在同一個(gè)凹槽內(nèi)下行,在套囊的近端設(shè)一排出藥孔,局麻藥注入時(shí),呈噴射狀出藥,,對(duì)聲門下產(chǎn)生局部麻醉作用,全麻結(jié)束時(shí),可以最大限度減淺麻醉,讓病人蘇醒,而應(yīng)激反應(yīng)低,氣道梗阻發(fā)生機(jī)率低,尤其是喉痙攣、支氣管痙攣的發(fā)生機(jī)率降低。 方法:通過2個(gè)試驗(yàn)對(duì)表面麻醉的可行性和安全性進(jìn)行驗(yàn)證,分別為:試驗(yàn)一擇期腹部手術(shù)60例,ASAⅡ級(jí),無心律失常史,ECG均提示有心肌缺血或不同程度的左心室擴(kuò)大、ST-T改變。隨機(jī)分為表麻組(B組)和對(duì)照組(D組),每組30例。表麻組通過局麻藥注藥口把局部麻醉藥通過局麻藥注藥管、局麻藥出藥孔注至氣管插管上的套囊與患者聲帶之間的患者氣管和聲帶表面起到表面麻醉作用。試驗(yàn)二選擇需要做全麻手術(shù)的患者40例,隨機(jī)分為表麻組和對(duì)照組各20例。全麻患者符合拔管指征時(shí),表麻組通過導(dǎo)管推注利多卡因,對(duì)照組則用氯化鈉。 結(jié)果:試驗(yàn)一HR、SBP、DBP、RPP在B組T3、T4、T5時(shí)與T1比較無顯著性差異(P0.05),與T2比較各指標(biāo)顯著降低(P0.05),與D組比較亦顯著降低(P0.05,P0.01)。D組在吸痰拔管時(shí)有4例病人因SBP大于200mmHg各用烏拉地爾12.5mg,B組未出現(xiàn)此種情況。試驗(yàn)二表麻組Ⅰ組在T1時(shí)與T3、T4、T5時(shí)比較RPP、DBP、SBP、HR值無顯著性差異(P0.05),與T2比較各指標(biāo)則明顯降低(P0.05),與Ⅱ組比較則有顯著的降低(P0.01,P0.05)。 結(jié)論:可實(shí)施表面麻醉的氣管插管的制作和臨床應(yīng)用可行,且麻醉效果良好,能最大限度減少麻醉所帶來的并發(fā)癥,大大減輕了病人的痛苦。在全麻拔管時(shí)是一種較為實(shí)用的方法。
[Abstract]:Objective: to investigate the preparation and clinical application of tracheal intubation with surface anesthesia. How to make it: we add a tube to the glottis, which goes down in the same groove as the air bag's injection pipe, and has a discharge hole in the proximal end of the capsule. When the local anesthetic is injected, the drug is sprayed. At the end of general anesthesia, the local anesthesia can be reduced to the maximum extent and the patient can wake up, but the stress response is low, the probability of airway obstruction is low, especially the laryngeal spasm, the occurrence rate of bronchospasm is reduced. Methods: the feasibility and safety of surface anesthesia were verified by two tests. The results were as follows: in trial 1, 60 patients with ASA 鈪
