[ACUTE KIDNEY INJURY IN PATIENTS WITH MULTIPLE ORGAN DYSFUNCTION SYNDROME IN THE EARLY PERIOD AFTER CARDIAC SURGERY].

UNLABELLED: Acute kidney injury can greatly increase the severity of multiple organ dysfunction syndrome (MODS) and impair patient outcomes.

OBJECTIVE: To study the clinical significance of acute kidney injury in patients with MODS in early postoperative period after cardiac surgety and its influence, on the severity of the patient condition and outcomes.

MATERIALS AND METHODS: The study involved 117 patients aged 57.2 ± 1.2 years. The Group 1, control, included 74 patients with uncomplicated postoperative period; the Group 2--43 patients with MODS, who were divided into the survivors (33 patients, group 2a) and deaths (10 patients, group 2b).

RESULTS: In Group 2. thefollowingparaineters were higher--the volume of blood loss by 1.5 times (p = 0,001), the duration of the cardiopulmonary bypass 1.7 times (p 0.001), and aortic clamping 1.6 times (p = 0,001). Group 2a and 2b on these indicators did not differ Average scale Group 2b was 1,3-fold higher than in survivors (p = 0,001). Patients differ in the severity of the central nervous system disorders (the average score of Glasgow Coma Scale survivors was 1.3 times higher P = 0,001) and severity of acute kidney injury On a RIFLE scale patients of group 2a normal data was observed in 12%, the stage of risk in 61%, and damage in 27%. In 50% of the dead was a stage of disease (p = 0.04), the rest--damage. In the dynamics of the group 2b impaired renal and hepatic functions have progressed. By day 3 ASTwas on average 2-fold higher (p = 0.01), ALT (1.9 fold, p = 0,001), alkaline phosphatase 1.5 times (p = 0.001), while the total blood protein below 1.3 times (p = 0.00 1), than in group 2a. Creatinine in patients of Group 2b was 1.4 tunes higher (p = 0,036), urea 1.6 (p = 0.026), u-NGAL 7 times higher (p = 0.001), than in group 2a.

CONCLUSIONS: Long cardiopulmonary bypass, clamping of the aorta and a large amount of perioperative the risk of MODS in the early postoperative period, but do not affect the outcome. On the background of the dzvelopment of MODS an average score on MODS-2 scale died was 1.3 times higher in Group 2b than in survivors. Marked renal dysfunction in cardiac surgical patients with MODS is a sign of poor prognosis. With the development of MODS, a renal dysfunction ahead worsens hepatic function. The value qf the marker u-NGAL is the strongest indicator of the severity of acute kidney injury and poor outcome of treatment in these patients.
