SGB in Management of Patients With PDPH Using TCD

Sphenopalatine Ganglion Block is performed by a hollow culture swab that is connected with a 21-gauge syringe filled with three ml 2% lidocaine, inserted parallel to the floor of the nose until resistance is felt. The swab is at the posterior pharyngeal wall superior to the middle turbinate. The applicator was kept in the nostril for five to ten mins. The same procedure is done also in the second nostril. The patients are then examined by TCD.
