“…Lumbar puncture can measure intracranial pressure and collect cerebrospinal fluid for culture and biochemical indexes, and continuous drainage of the lumbar pool can also measure intracranial pressure and collect cerebrospinal fluid for culture and biochemical indexes [12]. However, the success rate of bacterial culture of cerebrospinal fluid in intracranial infections in clinical practice is low, requiring repeated and multiple cultures and biochemical indicators [13]; continuous lumbar pool drainage has significant advantages in the treatment of intracranial infections, such as the advantages of requiring only a single lumbar puncture, high success rate, controlled drainage rate, avoidance of associated adverse effects, easy detection of drained cerebrospinal fluid, and large cumulative drainage volume [14].…”
