Abstract
Rewarming in the postoperative period after hypothermic cardiopulmonary bypass is often associated with hemodynamic and ventilatory instability. Temperature changes, paco2 values, and delivered mechanical ventilation were observed for the first 12 hr in the intensive care unit in 73 patients who had undergone cardiac surgery with hypothermic cardiopulmonary bypass. Mean rectal temperature increased from 34.7 to 38.3°C over the first 8 hr after admission to the intensive care unit (P < 0.001). The temperature curve was sigmoid rather than linear., and the most rapid rate of temperature increase occurred 2–4 hr after admission. During rewarming, the most common abnormality of paco2 on mechanical ventilation was acute respiratory acidosis (paco2 > 45 mm Hg, pH < 7.35), which occurred in 42% of patients. This suggests that ventilatory management in the early postoperative period after hypothermic cardiopulmonary bypass should be carefully adjusted to the increased metabolic rate during rapid rewarmingThis publication has 0 references indexed in Scilit:
