Abstrakt		Introduction Shock or shock related organ failure is the most common cause of death in traumatized patients. The consequences of shock to the alimentary system are the most responsible for the late complications in shock patients. Already in the early phase of shock, hypoxic damage of alimentary system developed. Severity of damage is proportional to the duration of hypoxia. We assume that therapy enabling enough splanhnic blood supply could significantly reduce severe complications in shock patients. According to the literature, gastric tonometry is an optimal method for assessment of splanhnic blood supply, tissue oxygenation and cell energy balance. The aim of our research was to find out if gastric tonometry could be a useful method for assessment of the early phase of shock. Patients and methods Twenty-two adult polytraumatized patients, admitted to the intensive care unit and treated on the standard manner were included in our study. Pulmonary artery catheter and a gastric tonometric tube were inserted in all cases. Measurements and calculations of each predicted shock indicator were performed at 8 hours intervals during the 72 hours. Two different methods were used simultaneously to detect whether the patient is in the state of shock: the bolus thermodilution technique and gastric tonometry. The first method determined five parameters: mean artery pressure (MAP), cardiac index (CI), oxygen delivery to the tissues, oxygen consumption and systemic vascular resistance index (SVRI). Gastric tonometry estimated two parameters: pHi and pC02 gap. By both methods shock was defined by arbitrary determined cut off values of measured parameters. Shock was diagnosed if one of different parameters exceeded the cut off value. (Abstract truncated at 2000 characters)
