Ensuring adequate oxygen delivery to the tissues with respect to oxygen demand is the treatment goal in patients undergoing coronary artery surgery (CAS). In this study we examined changes in temperature, arterial oxygen saturation (SaO2), cardiac index (CI), oxygen consumption (VO2), and mixed venous oxygen saturation (SvO2) over the initial 4-hour rewarming period in 36 patients having CAS. When patients were admitted to the intensive care unit the mean temperature was 36.27 degrees C, and it increased to 37.50 degrees C; SaO2 was 97.67% at the beginning and end of the 4-hour period; CI was 2.88 L/min/m2 and rose to 3.00 L/min/m2; VO2 was high at 0.320 L/min on admission and remained high at 0.290 L/min at the end of the 4-hour rewarming period; and SvO2 was 70.83% initially and declined to 66.53% in the same period of time. Continuous SvO2 monitoring was valuable in the ongoing assessment and management of the patients in stable, mildly hypothermic condition after CAS during the 4-hour postoperative rewarming period. |
