Objective: To compare the efficacy of sphenopalatine ganglion block with greater occipital nerve block in the management of post-dural puncture headache in obstetric patients after cesarean section under spinal anesthesia.
Study Design: Quasi-experimental study
Place and Duration of Study: Department of Anesthesiology, Combined Military Hospital, Rawalpindi, Pakistan, Sep 2024 to Feb 2025.
Methodology: Patients in Group-S (n=70) received the sphenopalatine nerve block (SPNB) and patients in Group-G (n=70) received the greater occipital nerve block (GONB). Primary variables studied were median numeric rating scale (NRS) scores for pain (0-100) (0-No Pain to 100-Maximum pain imaginable) assessed at 1,6,12 and 24 hours between both groups, the total dose of rescue analgesia, the frequency of patients requiring epidural blood patch and patient satisfaction on the Likert scale.
Results: Median NRS scores before intervention between both groups were 45.00 (5.00) in Group-S versus 45.00 (5.00) in Group-G (p=0.875). Same scores assessed after 01 hour were 40.00 (5.00) versus 40.00 (5.00) between both groups (p=0.880). Assessment after 06 hours showed median scores of 30.00 (5.00) in Group-S versus 30.00 (9.00) in Group-G (0.650). After 12 hours, median scores were 15.00 (5.00) versus 25.00 (0.00) between both groups (p<0.001), and assessment after 24 hours showed median scores of 15.00 (0.00) in Group-S versus 20.00 (10.00) in Group-G (p<0.001).
Conclusion: It was concluded that sphenopalatine block offers better pain scores and patient satisfaction with reduced need for rescue analgesia, with both blocks offering good results with minimal side effects.
