Patients were divided into tolerance group (n\u2009=\u200997) and intolerance group (n\u2009=\u200953) according to whether EN was tolerated or not. The study indexes include baseline characteristics [gender, age, weight, body mass index (BMI), scores of acute physiology and chronic health evaluation II system (APACHE II), comorbidity, time in-hospital, prognosis], clinical indexes [mean arterial pressure (MAP), time of mechanical ventilation (MV), norepinephrine dose at the time of starting EN, using of sedative drug, gastrointestinal motility drugs and cardiotonic drugs], EN indexes (timing of starting EN, speed of EN infusion, calorie of EN per day, EN target percent), and gastrointestinal intolerance index [residual gastric volume\u2009&gt;\u2009250 ml, vomiting, aspiration, gastrointestinal bleeding, blood lactic acid (BLA)]. Student-t test and Mann-Whitney test were used for test of measurement data. Chi-square test and fisher exact test were used for comparison of categorical data.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>There were 51 (52.58%) male and 46 (47.42%) female patients with a median age of 66.4\u2009\u00b1\u200912.8 years old in tolerance group. There were 29 (54.72%) male and 24 (45.28%) female patients with a median age 67.3\u2009\u00b1\u200912.5 years old in intolerance group. The weight and BMI were significantly higher in intolerance group than those of tolerance group (both P\u2009&lt;\u20090.001). There was no significant difference of comorbidity rate between two groups (all P\u2009&gt;\u20090.05). Before the overlapping time of EN and norepinephrine, there were significantly more patients receiving gastrointestinal motility drugs in intolerance group compared with tolerance group (58.49% vs. 20.62%, P\u2009&lt;\u20090.001). Patients in tolerance group had significantly less residual volume in gastric than that of intolerance group (188.00\u2009\u00b1\u200952.32 vs. 247.83\u2009\u00b1\u200934.95, P\u2009&lt;\u20090.001). The rate of residual volume in gastric\u2009&gt;\u2009250ml (9.28% vs. 37.74%, P\u2009&lt;\u20090.001), vomiting (15.46% vs. 35.85%, P\u2009=\u20090.004) and aspiration(16.49% vs. 33.96%, P\u2009=\u20090.018) were significantly lower in tolerance group than those of intolerance group. The BLA in tolerance group was significantly lower than that of intolerance group (1.84\u2009\u00b1\u20090.63 vs. 2.90\u2009\u00b1\u20091.5 3mmol\/L,P\u2009&lt;\u20090.001). There were significantly more patients with increased BLA (75.47% vs. 30.93%, P\u2009&lt;\u20090.001) and &gt;\u20092mmol BLA rising (43.40% vs. 8.25%, P\u2009&lt;\u20090.001) in intolerance group than those of tolerance group. Patients in tolerance group had significantly lower time of starting EN (40.97\u2009\u00b1\u20099.53 vs. 49.85\u2009\u00b1\u200911.61\u00a0h, P\u2009&lt;\u20090.001), dose of NE(0.23\u2009\u00b1\u20090.07 vs. 0.28\u2009\u00b1\u20090.10 ug\/kg\/min, P\u2009=\u20090.049), mortality in hospital (18.56% vs. 49.06%, P\u2009&lt;\u20090.001) and mortality in ICU (16.49% vs. 37.74%, P\u2009&lt;\u20090.001) compared with intolerance group.
