Summary

This study aims to investigate the ability of SPGB in the management of PDPH. Transcranial Doppler is also used as an measure to assess the block success by detecting the variability in the cerebral hemodynamics before and after the block.

Detailed description

This clinical trial is performed in postoperative orthopedic unit. In this study, 120 patients were enrolled who had an epidural anesthesia; 60 patients who developed PDPH joined the treatment group (A) and received the SP block. They are assessed before the procedure by NRS and at 30 mins, 2h, 4h, 6h, 12h, and 24h after the procedure. Patients are also assessed by TCD before and after the block. The control group (B) included 60 patients with no PDPH.

Conditions

• Post-Dural Puncture Headache

Interventions

Type	Name	Description
DRUG	Sphenopalatine Ganglion Block using 2% lidocaine	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.
