Patient Care. Preparation of the patient for this procedure should include a detailed explanation, because insertion of a needle so close to the brain may cause apprehension. The physician may request that the back of the neck be shaved. The patient is positioned on either side with the head bent forward and held firmly by an attendant. Complications seldom occur, but the patient should be observed for signs of dyspnea or cyanosis during and immediately after the procedure. A cisternal puncture is often done in the outpatient clinic, and the patient is allowed to go home soon after it is completed.
