摘要 目的探讨机械通气的鼻饲患者中胃残液量与误吸的相关性。方法选取入住ICU需机械通气的鼻饲患者32例,以开始鼻饲前3d为研究时间,以支气管分泌物中检出胃蛋白酶为存在误吸,每4h监测胃残液量及支气管分泌物胃蛋白酶含量/误吸,根据回抽的胃残量多少间隔50m1分组,分析胃残液量与支气管分泌物胃蛋白酶含量/误吸的关系。结果总误吸发生率为70.1%,胃残液量与误吸发生频次呈正相关(r=0.48,P=0.006);组间支气管分泌物胃蛋白酶含量与胃残液量差异有统计学意义(P=0.000);胃残液量0~50ml组与51—100ml比较支气管分泌物胃蛋白酶的含量无统计学意义,但此两组分别与胃残液量100ml以上各组比较差异均有统计学意义(P〈0.05)。结论机械通气患者鼻饲期间误吸发生率极高,且与胃残液量呈正相关;支气管分泌物胃蛋白酶的含量亦与胃残液量呈正相关,胃残液量超过100ml时,支气管分泌物胃蛋白酶含量明显增高。
