目的:探討老年人腹部手術(shù)中應(yīng)用七氟醚與異丙酚麻醉對(duì)其術(shù)后認(rèn)知功能的影響。方法:收治腹部手術(shù)患者80例,隨機(jī)分為兩組。對(duì)照組給予七氟醚麻醉,觀察組給予異丙酚麻醉,比較兩組術(shù)后恢復(fù)情況、認(rèn)知功能情況。結(jié)果:觀察組拔管時(shí)間、輕喚睜眼時(shí)間短于對(duì)照組,自主呼吸恢復(fù)時(shí)間長于對(duì)照組(P<0.05)。與對(duì)照組患者相比,觀察組患者術(shù)后1 h、3 h的MMSE評(píng)分更高(P<0.05)。結(jié)論:異丙酚與七氟醚影響老年人腹部手術(shù)后的認(rèn)知功能,異丙酚對(duì)認(rèn)知功能影響較小。
七氟醚;異丙酚;認(rèn)知功能
認(rèn)知功能是人體大腦的特有生理功能。患者腹部手術(shù)麻醉時(shí)可能會(huì)引起認(rèn)知功能障礙。七氟醚和異丙酚是一種新型麻醉藥物,逐漸被廣泛應(yīng)用于臨床,但其與認(rèn)知功能關(guān)系的研究尚少[1]。本研究探討老年人腹部手術(shù)中應(yīng)用七氟醚與異丙酚麻醉對(duì)其認(rèn)知功能的影響,現(xiàn)報(bào)告如下。
2013年3月-2015年8月收治腹部手術(shù)患者80例,男44例,女36例;年齡61~76歲,平均年齡(70.6±9.2)歲;闌尾炎手術(shù)36例,膽囊手術(shù)34例,其他10例;大學(xué)及以上8例,高中46例,初中16例,小學(xué)及以下10例。排除標(biāo)準(zhǔn):老年癡呆癥患者;精神疾病或者精神疾病家族史患者;各種認(rèn)知功能障礙疾病患者。按照簡單隨機(jī)法將所有患者分成對(duì)照組、觀察組,每組40例。兩組基線資料比較,差異無統(tǒng)計(jì)學(xué)意義(P>0.05)。
方法:監(jiān)測(cè)兩組患者的生命特征,如血壓、呼吸以及心率等。插管成功后接麻醉機(jī),并合理調(diào)節(jié)呼吸參數(shù)。術(shù)中,對(duì)照組患者給予七氟醚1~1.3 MAC,觀察組給予靶控輸注異丙酚2~4 μg/mL保持麻醉;手術(shù)開始時(shí),靶控輸注瑞芬太尼2.5~4.0 ng/mL。術(shù)中腦電雙頻指數(shù)BIS 50~60;縫合傷口時(shí),停止輸注異丙酚以及吸入七氟醚;縫合完全結(jié)束時(shí),停止輸注瑞芬太尼。所有患者手術(shù)后均給予自控硬膜外鎮(zhèn)痛(PCEA)、羅哌卡因500 mg聯(lián)合芬太尼0.5 mg,共250 mL,手術(shù)結(jié)束時(shí)給予4 mL,持續(xù)輸注4 mL/h,自控量4 mL,鎖定時(shí)間25 min。
觀察指標(biāo):觀察并記錄兩組拔管時(shí)間、自主呼吸恢復(fù)時(shí)間、輕喚睜眼時(shí)間。采用MMSE評(píng)分對(duì)患者術(shù)前、術(shù)后1 h、3 h、6 h、12 h、24 h和48 h的認(rèn)知功能進(jìn)行評(píng)價(jià)。
統(tǒng)計(jì)學(xué)方法:采用SPSS 19.0統(tǒng)計(jì)軟件分析數(shù)據(jù),計(jì)量資料采用(x±s)表示,組間比較采用t檢驗(yàn),P<0.05表示差異具有統(tǒng)計(jì)學(xué)意義。
兩組拔管時(shí)間、輕喚睜眼時(shí)間、自主呼吸恢復(fù)時(shí)間比較:觀察組拔管時(shí)間、輕喚睜眼時(shí)間短于對(duì)照組,自主呼吸恢復(fù)時(shí)間長于對(duì)照組,差異具有統(tǒng)計(jì)學(xué)意義(P<0.05),見表1。

兩組手術(shù)前后MMSE評(píng)分比較:觀察組術(shù)后1 h、3 h的MMSE評(píng)分低于術(shù)前,對(duì)照組術(shù)后1 h、3 h、6 h的MMSE評(píng)分低于術(shù)前,差異具有統(tǒng)計(jì)學(xué)意義(P<0.05)。與術(shù)前相比,觀察組患者術(shù)后12 h以及對(duì)照組患者術(shù)后6 h的差異無統(tǒng)計(jì)學(xué)意義(P>0.05)。與對(duì)照組患者相比,觀察組患者術(shù)后1 h、3 h的MMSE評(píng)分更高,差異有統(tǒng)計(jì)學(xué)意義(t=6.342、7.343,P<0.05)。見表2。

Objective:To investigate the effect of sevoflurane and propofol anesthesia on the postoperative cognitive function of elderly abdominal surgery.Methods:80 cases of patients with abdominal surgery were divided into two groups randomly.The control group was given sevoflurane anesthesia,and the observation group was given propofol anesthesia.The postoperative recovery and cognitive function between groups were compared.Results:The extubation time,eye opening time upon calling in the observation group were shorter than those in the control group,and the recovery time of spontaneous breathing was longer than that in the control group(P<0.05).Compared with the control group,the MMSE scores in the observation group at the point of 1 h and 3 h after operation were higher(P<0.05).Conclusion:Propofol and sevoflurane had effect on the cognitive function of senile patients after abdominal surgery,and propofol had less effect on cognitive function.
