Prediction of kidney damage in the syndrome of intra-abdominal hypertension

The syndrome of intra-abdominal hypertension and abdominal compartment syndrome can complicate the course of many surgical abdominal diseases and lead to the development and progression of multiple organ failure. In particular, impaired renal blood flow is an early and significant pathogenetic link of thanatogenesis in such patients. Mortality at an abdominal compartment syndrome reaches very significant figures — 42–68% and without treatment approaches 100%. The purpose of the work is to predict renal failure in patients with intra-abdominal hypertension syndrome and abdominal compartment syndrome. A survey of 40 patients with acute surgical abdominal pathology and signs of intra-abdominal hypertension was performed. Blood pressure measurement was performed according to the recommendations of the conciliation commission on the problem of intra-abdominal hypertension syndrome (SIGA) from 2004. Also, the calculation of perfusion pressure of the abdominal cavity was performed, which is the difference between mean arterial pressure and intraabdominal pressure. The level of perfusion pressure is less than 60 mm Hg. Art. correlates with survival of patients. Determination of cystatin C was performed in the first 48 hours after hospitalization of patients in VAIT. The calculation of the results was carried out according to the standard t-criterion calculation formulas in the Exel tables. It was found that of 40 patients died — 13, and survived — 27. The reliable difference between the indicators of intra-abdominal pressure in surviving and deceased patients was acquired only at the end of the third day of observation, whereas the abdominal perfusion pressure indices significantly differed already in the first day. In the analysis of cytatine C in surviving patients, the biomarker values were 1,299±0.827, whereas in those who died 1,882±0.828, the statistical deviation was significant at p≤0.05. Thus: the cytosine C score, in combination with the dynamics of abdominal perfusion tick, can be considered as a marker that may predict the development of renal insufficiency in patients with SIGA-AKS.
