Efficacy of Sphenopalatine Block in Patients with Post-Dural Puncture Headache after Cesarean Section

Abstract

Our study emphasised the efficacy of sphenopalatine ganglion block (SPGB) in patients with post-dural puncture headache (PDPH) after cesarean section. In this clinical experiment, the effectiveness of the SPGB in treating PDPH in pregnant women was examined. 40 individuals with PDPH were randomly divided into two equal groups for a prospective randomised clinical trial. The group receiving paracetamol (PG) for one day, the patients take 1 gram of paracetamol intravenously three times daily. Rescue analgesia in intravenous ketorolac is administered if sufficient pain relief cannot be found. Block group (SPGBG): Each nostril of the patients received a 3 ml dose of a lignocaine and dexamethasone mixture during bilateral SPGB. Recordings were made of the heart rate, arterial pressure, and mean pain score. Additionally noted were the initiation and end of the analgesic effect, any adverse effects, the amount of ketorolac used, patient satisfaction, and whether the patient stayed in the hospital for an EBP (epidural blood patch) or was discharged after 24 hours. The block group's pain perception (measured by a numeric rating scale [NRS]) was usually less during the research, with only a significant difference until the first two hours following the block when analgesia began more quickly and lasted longer. The hospital stay of the block group for EBP was substantially shorter and had higher patient satisfaction than the control group, which also had a much lower overall dose of the rescue analgesic in milligrams. Conclusions: Trans-nasal SPGB is a non-invasive, safe, simple, and effective treatment for post-dural puncture headache (PDPH) with a low complication rate.
