title: [Cerebrospinal fluid IgG, pH, oxygen partial pressure K+ ion study in the diagnosis and prognosis of tuberculous meningitis with brain failure].
abstract: 311 cases of tuberculous meningitis were studied. Cerebro-spinal fluid (CSF), pH, K+ ion were observed in the brain failure (BF). As the BF occurs, IgG in CSF evidently goes down to 15.9 mg/L (normal.35.6 mg/L), P less than 0.01 and PO2 drops to 3.50 kPa (normal. 6.198 kPa) P less than 0.01, indicating low oxygen in CSF, PCO2 in CSF is a little higher, 7.3 kPa (normal. 6.07 kPa), forming high carbonate in CSF and acidosis. CSF shows that the K+ is lower down to 1.7 mmol/L (normal. 2.53 mmol/L) P less than 0.01, that is the case of BF in its early stage. In case of coma, K+ in CSF is 3.8 mmol/L, P less than 0.01. late stage.
