Q: What is the usual standard for drawing cerebrospinal fluid (CSF) during management of Intra-Cranial Pressure (ICP) management?

Answer: Ventricular CSF drainage is usually done as the first line of invasive management particularly when ICP goes above 20 mmHg. CSF should be drained at a rate of approximately 1-2 cc/minute for 2 minutes. If further removal is required, the interval of at least 2 minutes should be given in between drainages until the desirable ICP is achieved.
