1、喉面罩對(duì)老年高血壓患者腹腔鏡手術(shù)應(yīng)激反應(yīng)的影響作者:周文濤,張震波,張尚民,丁輝,王芳茹,李永宏,鄧博【摘要】目的:比較麻醉喉面罩與氣管插管對(duì)老年高血壓患者腹腔鏡膽囊切除術(shù)(laparoscopiccholecystectomy,LC)圍術(shù)期應(yīng)激反應(yīng)的影響。方法:擇期老年高血壓患者行LC60例,ASAⅠ~Ⅱ級(jí),隨機(jī)分成喉面罩組(A組)和導(dǎo)管組(B組),通氣設(shè)置:潮氣量(VT)6~8ml/kg,頻率16~18/min,間歇正壓通氣(IPPV),呼吸末正壓3cmH2O,CO2氣腹(壓力<12mmHg),保持PETCO218~22.5mmHg。記錄兩組在麻醉誘導(dǎo)前
2、、插管后5min、氣腹后、拔管前、拔管后5min5個(gè)時(shí)點(diǎn)的心率(HR),心率與收縮壓乘積(RPP),血糖,皮質(zhì)醇拔管時(shí)嗆咳發(fā)生率等指標(biāo)。結(jié)果:氣腹對(duì)兩組循環(huán)有明顯的增強(qiáng)作用,心率與收縮壓乘積較氣腹前明顯升高(P<0.05)。兩組血糖自插管后均不同程度的上升,B組于插管后上升更明顯,與A組比較差異有統(tǒng)計(jì)學(xué)意義(P<0.05);兩組術(shù)畢時(shí)皮質(zhì)醇水平均明顯上升(P<0.05),B組拔管后繼續(xù)上升;A組拔管時(shí)嗆咳發(fā)生率低。結(jié)論:老年高血壓患者使用喉面罩,在12mmHg8CO2氣腹壓力下,不會(huì)影響肺通氣效果,應(yīng)激反應(yīng)輕,心肌耗氧少,血液動(dòng)力學(xué)穩(wěn)定,術(shù)畢對(duì)喉
3、面罩反應(yīng)輕,耐受時(shí)間延長(zhǎng)有利于輔助通氣,拔管后通氣改善更好。但應(yīng)盡量減少氣腹壓力,氣腹后、間歇正壓通氣期間應(yīng)設(shè)一定呼吸末正壓,可適當(dāng)增加呼吸頻率,避免發(fā)生高CO2血癥?!娟P(guān)鍵詞】喉面罩;麻醉,靜脈;老年人;高血壓;應(yīng)激【Abstract】Objective:Toevaluatetheeffectoflaryngealmaskonstressreactionoftheagedpatientswithhypertensionduringthelaparoscopiccholecystectomy.Methods:Sixtyagedpatients,withASAgra
