An Optimizing of the Resuscitative Patterns by Use of Balanced Crystalloids and Colloids and the Non-Invasive Hemodynamic Monitoring

Methods: The extensively burnt patients (age range 18-75 years) with second and the third degree burns, with TBSA above 15%, with or without inhalation injury will be included to the study within 2009-2010. The patients meeting inclusion criteria but with an adverse critical prognosis from the beginning of the hospitalization, with surgically insoluble extent of burns or the dialyzed patients will be excluded.The patients will be routinely monitored. We will use the continuous real-time hemodynamic monitoring through transpulmonal lithium dilution additionally. The monitor Lithium Dilution Cardiac Output (LIDCO) Plus permits through analysis of the arterial blood pressure trace to acquire items about CO, SVR and DO2 . In fluid resuscitation, we will use a combination of the balanced crystalloids and synthetic colloids (of the middle molecular weight) in the ratio 2 ml/kg/% TBSA : 1 ml/kg/% TBSA. The control group will be composed of the patients supervised in a standard way, volume resuscitated according to the Brooke or Parkland formulas. MAP > 65 torr, urine output 0,5 ml/kg/h, CI 2,5 - 4,0 l/min/m2, DO2I 500 - 600 ml/min/m2 are the goals.We will measure the levels of proANP (pro Natriuretic peptide) and Angiotensin Converting Enzyme (ACE) at artificial ventilated patients. The plasma ACE and proANP concentrations were measured by commercially available ELISA immunoassays.

Conclusions: We will evaluate the total fluid balance at day 1, 2 and cumulative fluid balance at day 7, reversal of organ dysfunction according to SOFA score at day 3 and 7 in both group. The days of invasive ventilatory support, length of ICU stay, ICU survival, total length of hospital stay and hospital survival are the additional endpoints.
