In most cases, patients are not sent home with a lumbar drain, as the drain typically requires close monitoring to ensure proper functioning, prevent complications, and manage any issues that may arise. Lumbar drains are usually placed in a hospital setting where the patient's vital signs, intracranial pressure, and the amount of cerebrospinal fluid (CSF) drained can be closely observed. Once the underlying condition has been treated or managed and the lumbar drain is no longer needed, it will be carefully removed before the patient is discharged.
