Effects of terlipressin combined with norepinephrine on liver function and prognosis of patients with septic shock / 国际生物医学工程杂志

ABSTRACT

Objective:To investigate the effects of terlipressin (TP) combined with norepinephrine (NE) on liver function and prognosis of patients with septic shock.Methods:From June 2018 to December 2019, 96 patients with septic shock and liver function impairment admitted to the ICU of Tianjin First Central Hospital were selected for prospective study. The patients were divided into control group( n=48) and experiment group( n=48) by randomize number table derived by computer. Based on conventional treatment, NE was used in control group, and the low dose continuous infusion of TP combined with NE was used in experiment group. Serial measurements of aspartate aminotransferase (AST), alanine aminotransferase (ALT), serum total bilirubin (TBIL), heart rate and mean arterial pressure (MAP), and blood lactic acid levels were made before the treatment and after the treatment at 24 and 48 hours. The mechanical ventilation time, intensive care unit (ICU) stay, and total length of hospital stay of the two groups were compared, and the 28-day mortality and serious adverse reactions of the two groups was also calculated. Results:The levels of ALT, AST, TBIL, heart rate and blood Lac of the two groups were significantly decreased after the treatment (all P<0.01), and the level of MAP was significantly increased (all P<0.01). Compared with the control group, the levels of 24-hour and 48-hour ALT, AST, TBIL, blood Lac of the experiment group were significantly decreased (all P<0.05), and the 48-hour level of MAP was significantly increased (all P<0.05), but there was no statistically significant difference between the two groups in the levels of 24-hour heart rate and 24-hour MAP (all P>0.05). Besides, there was no statistically significant difference between the two groups in the mechanical ventilation time, ICU stay, total length of hospital stay and the 28-day mortality (all P>0.05). And there were no serious adverse reactions such as avascular necrosis of the fingers and myocardial infraction in the two groups. Conclusions:In the treatment of septic shock, on the basic of adequate fluid resuscitation, continuous intravenous pumping of low-dose TP combined with NE can play a certain protective effect on the live, and the mechanisms of action may be mediated by stabilizing hemodynamics, reducing heart rate, reducing the level of blood Lac and improving liver perfusion, thereby protecting liver function in patients with septic shock.
