Paired sample t test.
SAP measurements did not demonstrate any difference at Tbasal-C/Tbasal-RW and 33°C (p > 0.05). SAP values during rewarming at 34°C, 35°C, 36°C were lower as compared to measurements in cooling period (p < 0.05). DAP measurements did not demonstrate any difference at 33°C (p > 0.05). DAP values during rewarming at Tbasal-RW, 34°C, 35°C, 36°C were lower as compared to the measurements during cooling period. MAP meaurements did not demonstrate any difference at Tbasal-C/Tbasal-RW and 33°C (p < 0.05). MAP values during rewarming at 34°C, 35°C, 36°C were lower as compared to measurements during cooling period (p < 0.05). HR and CVP measurement values at the same body temperature during rewarming and cooling period did nor demonstrate any difference (p > 0.05). CO measurements were higher during the rewarming period (p < 0.05). CI measurements were higher during the rewarming period (p < 0.05). GEDI and ELWI measurements during rewarming and cooling periods did not demonstrate any difference at the same body temperatures (p > 0.05). SVRI measurements during rewarming and cooling periods at 33°C did nor demonstrate any difference (p > 0.05). SVRI values during rewarming period at 34°C, 35°C, 36°C and Tbasal-RW period were lower (p < 0.05).
C: Cooling, RW: Rewarning, BT: Body temperature, SAP: Systolic arterial pressure, DAP: Diastolic arterial pressure, MAP: Mean arterial pressure, HR: Heart rate, CVP: Central venous pressure, SVRI: Systemic vascular resistance index, CO: Cardiac output, CI: Cardiac index, GEDI: Global end-diastolic volume index, ELWI: Extravascular lung water index.
