【摘要】 本文对72例颅脑损伤病人进行脑脊液乳酸、丙酮酸及气体分析,按GCS分为重型组和轻中型组。结果表明:重型组乳酸/丙酮酸明显升高,>20/1,此比值为判断脑氧化还原状态的可靠指标,对估计伤情和预后有重要价值。本组伤者脑脊液pH值降低,此亦为估计伤情和预后的指标之一。更多还原

【Abstract】 The lactate and pyruvate levels and gas analysis of CSF were determined in 72 patients with head injury. The patients were classified according to GCS into severe type and light-middle type. The results showed that lactate/pyruvate ratio increases,>20/ 1 in severe type. It is a reliable index of the redox state of the brain tissue. This index is valuable to estimate the severity and prognosis of head injury. The pH of CSF was reduced in the patients with head injury. It is also one of the indexes to estimate the severity and prognosis of head injury.更多还原
