Description
A thin, hollow needle used to access the subarachnoid space in the lumbar region for diagnostic lumbar puncture to obtain cerebrospinal fluid or for administration of intrathecal medications and spinal anesthesia, with design features such as atraumatic pencil point tips to reduce postdural puncture headache risk. Proper patient positioning, sterile technique, and knowledge of anatomic landmarks are essential to minimize complications including bleeding, infection, and nerve injury. Postprocedure monitoring for neurologic changes and headache management protocols support patient safety and comfort.
