RT Journal Article SR Electronic T1 Effects of vasoactive drugs on hepatic and intestinal circulation and intestinal barrier in patients with septic shock JF Journal of Investigative Medicine JO J Investig Med FD BMJ Publishing Group Ltd SP 833 OP 837 DO 10.1136/jim-2020-001685 VO 69 IS 4 A1 Jie Liu A1 Min Zheng A1 Xu Zhao A1 Yong-Jiu Zha A1 Hu-Nian Li A1 Guang-Qing Huang YR 2021 UL http://hw-f5-jim.highwire.org/content/69/4/833.abstract AB In this study, 60 patients with septic shock were selected over the course of 1 year, and the effects of dopamine and norepinephrine combined with dobutamine on hepatic and intestinal circulation and intestinal barrier in patients with septic shock were studied by comparison between the control group and the experimental group. All patients received mechanical ventilation to maintain breathing at 14 to 20 times/min. The experimental group was treated with vascular active drugs after adequate rehydration, and the control group only received adequate rehydration. There were extremely significant differences (p<0.01) in the total effective rate of each group. There were significant differences in the hemodynamic indexes in each group (p<0.05). There was a significant difference in total 24-hour bile output (p<0.01). There were significant differences in liver function and blood lipid values in patients (p<0.01). There were significant differences in the repair of epithelial injury at 0 hour, 48 hours and 96 hours (p<0.01). There were significant differences in the transmembrane resistance of monolayer cells (p<0.01). The expression differences of three proteins ZO-1, occludin and β-actin were also significant, among which the three proteins in the control group were weak, while those in groups A and B were strong. The expression of tight junction protein in monolayer cells was weakly positive in expression and strong in other proteins. In conclusion, vasoactive drugs had significant effects on hepatic and intestinal circulation and intestinal barrier in patients with septic shock.Data are available on reasonable request.
