Hemodynamic efficacy and safety of using modified gelatin solution and polyhydric alcohol solution for fluid resuscitation of patients with septic shock

Abstract

Objective ‒ to compare the hemodynamic effects and safety of the infusion of succinylated gelatin solution, sorbitol-containing solution, and 0.9 % normal saline (0.9 % sodium chloride), analyze their effect on the treatment of septic shock and mortality. Materials and methods. A prospective randomized clinical trial that included 94 adult patients with an active surgical infection and septic shock was conducted. There were 34 (36.2 %) male and 60 (63.8 %) female patients aged between 19 and 96 years, mean age was (66.51 ± 17.06) years. An appropriate solution in a volume of 500 ml was used for resuscitation, then hemodynamic and other clinical and laboratory parameters were monitored. Results. There was no significant difference in mean arterial pressure (MAP) between the 3 groups until the 40th minute (p>0.05). At the 45th minute MAP in the NS group differed only from MAP in the Gel group (p=0.007). At the 50th minute MAP in the NS group did not differ from the baseline (p=0.139). From the 50th minute to 2 hours, MAP in the Gel and Sorb groups was higher than in the NS group in all measurements (p0.05). Cardiac output (CO) did not differ up to the 30th minute (p>0.05), at the 35th minute, CO differed only between Gel and NS groups (p=0.019), from the 40th minute to 2 hour CO in Gel and Sorb groups were significantly higher than in NS group in all measurements (p0.05), from the 35th minute to the 45th minute a significant difference was found only between Gel and NS groups (pConclusions. In our observations, when using these three types of solution in patients with septic shock, hemodynamic effects up to the 40th minute did not differ between groups. From the 40th minute to 2 hour, the volemic effect of 4 % succinylated gelatin solution and balanced polyionic solution with 6 % sorbitol was significantly better, compared to the 0.9 % sodium chloride solution. The volume of solutions used in these three groups did not affect renal function in patients with septic shock. The amount of balanced polyionic solution used with 6 % sorbitol and 0.9 % sodium chloride solution did not affect blood coagulation function. But the use of 4 % succinyl gelatin solution reduced the concentration of fibrinogen in the blood. After infusion of the gelatin-containing solution with buffer formulations and sorbitol-containing solution with buffer formulations, the acid-base status of the blood was significantly improved compared to 0.9 % sodium chloride solution. Infusion of the gelatin-containing solution and 0.9 % sodium chloride solution did not affect the Glasgow coma score in patients. After infusion of the sorbitol-containing solution, patients’ consciousness was improved by this scale. The 28-day mortality did not differ significantly between groups.
