【摘要】目的 比較靶控輸注瑞芬太尼和丙泊酚全憑靜脈麻醉與地氟醚和芬太尼靜吸復(fù)合麻醉對老年患者術(shù)后認(rèn)知功能的影響。方法 選取80例年齡>60歲,擇期行腹鏡手術(shù)的患者,其ASA分級為Ⅰ~Ⅱ級,隨機(jī)分為試驗(yàn)組(40例)與對照組(40例)。試驗(yàn)組進(jìn)行靶控輸注丙泊酚復(fù)合瑞芬太尼全憑靜脈的麻醉方式,對照組進(jìn)行七氟醚和瑞芬太尼靜吸復(fù)合的麻醉方式。比較兩組患者術(shù)后恢復(fù)情況,并評價(jià)患者的認(rèn)知功能。結(jié)果 試驗(yàn)組患者術(shù)后蘇醒時(shí)間、拔管時(shí)間和拔管后語言應(yīng)答時(shí)間均優(yōu)于對照組(P<0.05);兩組各時(shí)間點(diǎn)MMSE評分比較差異無統(tǒng)計(jì)學(xué)意義(P>0.05),術(shù)后1 h、2 h、3 h兩組患者M(jìn)MSE評分均顯著下降(P<0.05)。結(jié)論 靶控輸注異丙酚復(fù)合瑞芬太尼全憑靜脈麻醉可引起老年患者一過性術(shù)后認(rèn)知功能障礙,但前者術(shù)后蘇醒更快。

術(shù)后認(rèn)知障礙是麻醉手術(shù)最重要并發(fā)癥之一,極大地影響患者術(shù)后的生活質(zhì)量。本文通過比較兩種不同的麻醉方式對老年患者術(shù)后認(rèn)知的影響,報(bào)道如下。
1.1基本資料:選取80例年齡>60歲,擇期行腹鏡手術(shù)的患者,其ASA分級為Ⅰ~Ⅱ級,隨機(jī)分為試驗(yàn)組(40例)與對照組(40例)。試驗(yàn)組男23例,女17例,年齡61~71歲,平均年齡(63±2.3)歲,對照組男20例,女20例,年齡60~69歲,平均年齡(64±2.2)歲。兩組患者年齡、性別、病程沒有統(tǒng)計(jì)學(xué)差異(P>0.05),可以比較。
1.2麻醉方法:兩組患者進(jìn)入手術(shù)室后開放外周靜脈,檢測生命體征。試驗(yàn)組采用靶控輸注全憑靜脈麻醉,靶控輸注丙泊酚(濃度3.5 μg/mL),在患者入睡后阿曲庫胺(0.1 mg/kg)和芬太尼(3.0 μg/kg),3 min后氣管插管,在手術(shù)過程中持續(xù)泵入瑞芬太尼[0.04~0.4 μg/(kg·min)]。對照組采用靜吸復(fù)合麻醉,高流量七氟醚預(yù)充5~8 min后,面罩吸入七氟醚誘導(dǎo),其余與試驗(yàn)組操作相同。
1.3觀察指標(biāo):觀察兩組患者術(shù)后恢復(fù)情況蘇醒時(shí)間、拔管時(shí)間和拔管后語言應(yīng)答時(shí)間。兩組患者術(shù)后認(rèn)知度評分(MMSE評分比較),分別比較術(shù)前、術(shù)后1 h、3 h、6 h、12 h、24 h。
1.4統(tǒng)計(jì)學(xué)分析:采用SPSS17.0統(tǒng)計(jì)軟件進(jìn)行統(tǒng)計(jì)學(xué)分析,數(shù)據(jù)以均數(shù)標(biāo)準(zhǔn)差(x-±s)表示,計(jì)量資料采用t檢驗(yàn),P<0.05,有統(tǒng)計(jì)學(xué)意義。
2.1兩組患者術(shù)后恢復(fù)情況比較見表1。試驗(yàn)組蘇醒時(shí)間、拔管時(shí)間、拔管后語言應(yīng)答時(shí)間均優(yōu)于對照組,差異有統(tǒng)計(jì)學(xué)意義(P<0.05)。
2.2兩組患者術(shù)后兩組患者術(shù)前MMSE評分差異無顯著性(P>0.05)。手術(shù)后各時(shí)間點(diǎn)差異沒有統(tǒng)計(jì)學(xué)意義(P>0.05),兩種患者手術(shù)后術(shù)后1 h、術(shù)后3 h、6 h與手術(shù)前比較值均有所降低,差異有統(tǒng)計(jì)學(xué)意義(P<0.05)。見表2。

[Abstract]Objective To compare postoperative cognitive function with the target-controlled infusionanesthesia and intravenous-inhalation combined anesthesia in elderly patients undergoing abdominal surgery. Methods 80 elderly patients (aged over 65-year-old, ASA Ⅰ-Ⅲ) undergoing selective abdominal surgery were randomly divided into experimental group (40) and control group (40). Compare two groups of patients with postoperative recovery,and evaluate patients' cognitive function. Results The times of eye opening, extubation and verbalization were markedly shorter in group experimental (P<0.05). The MMSE score at each time point is similar between the two groups has no statistical signifcance(P>0.05). 1 h、2 h、3 h after the operation,two groups of patients with MMSE score were signifcantly decline. Conclusion Target-control infusion anesthesia with propofol and intravenous -inhalation combined anesthesia with sevofurane can decline early postoperative cognitive function in elderly patients. Sevofurane has a more serious extent and a longer effect than propofol.
