Abstrakt     Introduction: In his research the author wanted to define the influence of different positive end expiratory pressures (PEEP) in mechanically ventilated newborns on the cardiac output (CO) using thoracic electrical bioimpendance (TEB). Currently there are not many papers describing the influence of PEEP on CO and even those have been assessed on a small number of newborns with contradicting results. The TEB method of measuring the CO with different PEEP values in mechanically ventilated newborns has not been used previously. Methods: This research is a prospective study performed in the Pediatric Department of the General Hospital in Maribor. Three measurements of CO were performed (M1, M2, M3) using TEB in 51 newborns aged 10.35 +- 6.8 days weighting 1.64 +- 0.6 kg and average gestational age of 31.29 +- 3.4 weeks at 3 different PEEP values. The patients were on synchronized intermittent mandatory mechanical ventilation do to the respiratory distress syndrome. Results: Using the F-test of arithmetical mean values the authors showed no significant difference of CO at different (0, 3, 6 cm H2O) PEEP values (M1: p=0.882, M2: p=0.785, M3: p=0.836). The mean value of CO measurements is 193.9 +- 55.2 ml/min/kg. Conclusions: With this study we have shown that PEEP up to 6 cm H2O most often used in conventional ventilation of newborns has no significant effect on CO. And that TEB is a valuable noninvasive method for evaluationg hemodinamical parameters in the newborns.
