【摘要】：目的觀察靜脈泵注腎上腺素在胃癌根治手術(shù)中對(duì)血鉀的影響。方法納入40例ASA分級(jí)Ⅱ~Ⅲ級(jí),擬在全麻下?lián)衿谛形改c道手術(shù)的患者,隨機(jī)分為試驗(yàn)組和對(duì)照組,試驗(yàn)組患者持續(xù)靜脈泵注腎上腺素0.03~0.1μg/(kg·min),對(duì)照組患者則泵注同等劑量的生理鹽水。監(jiān)測(cè)并比較兩組患者在不同時(shí)間點(diǎn)血鉀濃度的變化。結(jié)果試驗(yàn)組與對(duì)照組在性別構(gòu)成及年齡分布上差異未見(jiàn)統(tǒng)計(jì)學(xué)意義(P0.05)。與對(duì)照組相比,腎上腺素泵注30 min即T_3時(shí)刻患者血鉀下降差異有統(tǒng)計(jì)學(xué)意義(P0.05),且低于試驗(yàn)組的T_1時(shí)間點(diǎn)(P0.05);與對(duì)照組相比,停止泵注腎上腺素10 min即T_4時(shí)間點(diǎn)血鉀升高差異有統(tǒng)計(jì)學(xué)意義(P0.05),且高于試驗(yàn)組的T_1時(shí)間點(diǎn)(P0.05);與對(duì)照組相比T5時(shí)間點(diǎn)血鉀濃度依然較高,差異有統(tǒng)計(jì)學(xué)意義(P0.05),且高于試驗(yàn)組的T_1時(shí)間點(diǎn)(P0.05)。結(jié)論靜脈泵注腎上腺素在胃腸道手術(shù)中會(huì)降低血鉀濃度,停止腎上腺素泵注血鉀升高,并且高于基礎(chǔ)值。
