Effects of Hemodynamics on Dexmedetomidine Pretreatment for Older Patients Undergoing Double Lumen Endotracheal Intubation in General Anesthetic Induction Period/FANG Jun, WANG Sheng-bin.//Medical Innovation of China,2014,11(16):041-044
【Abstract】 Objective: To observe effects of hemodynamics on Dexmedetomidine pretreatment for thoracic surgery in older individuals via double lumen endotracheal intubation in General anesthetic induction period. Method: Forty ASA Ⅰ-Ⅲ patients with thoracic surgery were randomly divided into two groups: Group C (control group, n=20) and Group D (dexmedetomidine group D, n=20). In the group D, Dexmedetomidine was intravenously administered at 0.5 μg/kg for ten minutes. The patients in Group C were stated on 0.9% normal saline infusion at an equivalent rate. Drug induced using midazolam 0.02 mg/kg, fentanyl 4 μg/kg, vecuronium bromide 0.1 mg/kg and etomidate 0.3 mg/kg. Changes of cerebral state index (CSI), heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) were monitored before injection(T0), after injection at 2 minutes (T1), 4 minutes (T2), 6 minutes (T3), 8 minutes (T4), 10 minutes (T5), before intubation (T6), immediately after intubation (T7). Result: The CSI in Group D of T4(65.4±10.4), T5(60.3±7.9), T6(46.1±4.7) gradually decreased compared with the T0(96.5±4.0)(P<0.05), and was significantly less than that of Group C (P<0.05), the HR in Group D of T5, T6 significantly decreased compared with the T0(P<0.05). DBP, MAP, HR of T7 in Group C were higher than those of T6(P<0.05) during anesthetic induction. Conclusion: Dexmedetomidine pretreatment at 0.5 μg/kg for ten minutes has obvious sedative effect for elderly patients, not only can make CSI decreased, but also can reduce the cardiovascular stress responses during double lumen endotracheal intubation.

單肺通氣的手術(shù)患者常選擇雙腔氣管插管,由于雙腔氣管導(dǎo)管管徑粗大,加上需對(duì)導(dǎo)管精確定位時(shí)間相對(duì)較長(zhǎng),尤其是對(duì)老年患者的氣管刺激較強(qiáng),導(dǎo)致患者血流動(dòng)力學(xué)波動(dòng)大,因此需要在全麻誘導(dǎo)期對(duì)老年手術(shù)患者提供足夠的麻醉深度和維持平穩(wěn)的血流動(dòng)力學(xué)。本研究旨在觀察中等劑量右美托咪定(Dex)預(yù)給藥對(duì)60~75歲老年患者雙腔氣管插管操作前后麻醉深度指數(shù)(CSI)和全麻誘導(dǎo)期間血流動(dòng)力學(xué)的影響,為臨床提供參考。

本研究中D組HR在T4、T5時(shí)點(diǎn)比基礎(chǔ)值(T0)降低,HR作為心肌氧供需平衡的主要因素之一,在一定程度上HR下降有助于降低心肌氧耗,尤其對(duì)于老年伴有冠心病患者的心肌保護(hù)有明顯的益處。Ibacache[9]研究發(fā)現(xiàn),右美托咪定預(yù)處理通過激活α-2腎上腺素能受體,激活促生存激酶,通過細(xì)胞外調(diào)節(jié)蛋白激酶,蛋白激酶B和內(nèi)皮型一氧化氮合酶通路產(chǎn)生心肌保護(hù)作用;Biccard等[10]通過進(jìn)一步研究表明,接受α-2腎上腺素受體激動(dòng)劑治療的患者,無論是整體死亡率還是心肌梗死的風(fēng)險(xiǎn),都明顯降低。值得注意的是,近來有研究顯示右美托咪啶用于伴有左心室功能受損和心臟傳導(dǎo)阻滯的患者可發(fā)生不可控制的低血壓和心動(dòng)過緩[11-12]。
綜上所述,右美托咪定麻醉誘導(dǎo)前預(yù)處理(0.5 μg/kg),可以對(duì)單肺通氣老年手術(shù)患者麻醉誘導(dǎo)前產(chǎn)生安全有效鎮(zhèn)靜催眠作用,同時(shí)有效降低雙腔氣管插管對(duì)患者的應(yīng)激反應(yīng),有助于維持麻醉誘導(dǎo)期間的血流動(dòng)力學(xué)穩(wěn)定,也可能對(duì)老年患者具有一定的心肌保護(hù)作用;但也應(yīng)警惕右美托咪定應(yīng)用時(shí)可能發(fā)生偶發(fā)的不可控制的心動(dòng)過緩和嚴(yán)重低血壓。
