Abstract
Abstract. The work is devoted to the study of indicators of the acid-base state of arterial blood depending on the degree of morbid obesity in patients who were to undergo surgical bariatric interventions in 2012-2021. The study included 61 patients, whose age ranged from 22 to 69 years, body mass index from 40 to 91 kg/m2. The patients were divided into 3 groups depending on the degree of morbid obesity: group 1 - 20 patients with body mass index ≥ 40 (grade 3); group 2 - 25 patients with body mass index ≥ 50 (grade 4); group 3 - 16 patients with body mass index ≥ 60 (grade 5). Based on the data obtained, it was found that the acid-base state of arterial blood indicates the presence in patients with morbid obesity of pronounced changes in the direction of respiratory and metabolic acidosis with an increase in lactate, glucose, which significantly reduce the compensatory capabilities of the body. All studied indicators of the acid-base state of arterial blood in patients of group 1 tended to worsen. In patients of groups 2 and 3, the parameters of the acid-base state of arterial blood significantly worsen with an increase in the degree of morbid obesity. The maximum disruption of the acid-base state of arterial blood was found in patients with a body mass index ≥ 60.
