Abstract:
Objective: To observe the effect of cooling on systemic and regional oxygen metabolism in febrile critically ill patients. Method: Twenty-five critically ill patients with fever were cooled by ice blankets or by ibuprofen/indomethacin. Oxygen metabolism in whole body and regional organ and hemodynamics were measured. Result: As the temperature was reduced form 38.9?1.1℃ to 37.8?1.5℃,HR,cardiac index (CI),oxygen delivery (DO_2I),and oxygen consumption (VO_2I) decreased significantly,but gastric intramucosal pH increased from 7.26 to 7.37 and the PCO_2 difference between gastric rnucosa and arterial blood decreased markedly. PO_2 and oxygen content in cardiac coronary venous blood and oxygen exrtaction remained unchanged. Conclusion: After cooling the febrile pateints,CI, DO_2I and VO_2I decrease but tissue hypoxia can be improved.
