If the procedure is performed with the patient in the sitting position and an opening pressure is required (as in the case of pseudotumor cerebri), replace the stylet and have an assistant help the patient into the left lateral recumbent position. There are no data suggesting that a position change will increase the risk of spinal headache or transection of the spinal nerves. Take care, however, not to change the orientation of the spinal needle during this maneuver.
