Oxygen consumption calculated by the direct Fick method using a Swan-Ganz catheter (D-VO2) and indirect calorimetry using a metabolic computer (ID-VO2), carbon dioxide production calculated by the latter method, and respiratory quotient were determined pre- and postoperatively in 12 patients with acute hypertensive intracerebral hemorrhage and eight patients with acute ruptured intracranial aneurysm. The mean D-VO2 value was slightly lower than the mean ID-VO2 value, but had a significantly positive correlation. The regression curve was very close to the line of identity. The total metabolic expenditure can be calculated from D-VO2 and daily urinary nitrogen excretion. Direct calorimetry using a Swan-Ganz catheter is a simple method to evaluate metabolic expenditure in acute hemorrhagic cardiovascular disease.
采用Swan-Ganz导管通过直接Fick法计算的氧耗量(D-VO2)以及使用代谢计算机通过间接量热法计算的氧耗量(ID-VO2)、通过后一种方法计算的二氧化碳生成量和呼吸商,在12例急性高血压脑出血患者和8例急性颅内动脉瘤破裂患者术前和术后进行了测定。平均D-VO2值略低于平均ID-VO2值,但具有显著的正相关性。回归曲线非常接近恒等线。总代谢支出可根据D-VO2和每日尿氮排泄量计算得出。使用Swan-Ganz导管进行直接量热法是评估急性出血性心血管疾病代谢支出的一种简单方法。
