Often sepsis remains undiagnosed at the very beginning because of the concentration to the surgical pathology in perioperative period. This results in unacceptably high mortality. The investigators hypothesize that extended hemodynamic monitoring by focused transthoracic echocardiography will personalize early fluid resuscitation which will improve patient's outcome.~The goals of the investigators study are:~To conduct two-group randomized controlled clinical trial to compare patient management based on standard monitoring and extended hemodynamic monitoring by focused transthoracic echocardiography in patients undergoing urgent abdominal surgery due to peritonitis.~To demonstrate that patient management based on extended hemodynamic monitoring by focused echocardiography results in improved survival, reduced incidence of hemodynamic instability during perioperative period.~To compare an amount of administrated of intravenous fluids in both groups.~The investigators hypothesize that focused echocardiography monitoring will result in more administrated intravenous fluids during perioperative period.
The aim of the study is to identify the diagnostic value of the focused assessed echocardiography in septic patients undergoing urgent abdominal surgery due to peritonitis. The investigators expect that the incidence of hemodynamic instability will be reduced and the survival of the patients will be improved.
