| Abstract | ||||
| Background Conservative treatments of post-dural puncture headache (PDPH) may be unsuccessful, and the relief that is provided is frequently insufficient. This study aimed to meticulously explore the analgesic efficacy of the sphenopalatine ganglion (SPG) block when administered alone or in conjunction with the greater occipital nerve block (GONB) for the purpose of treating PDPH and with the aid of transcranial Doppler (TCD) to evaluate the cerebral hemodynamics before and after the block. Results VAS and modified Lybecker scores at 1, 6, and 24 h were statistically significantly lower in S and NAG groups compared to the control group with no statistically significant difference between S and NAG groups. With TCD, the mean velocity (MV) was significantly lower at 1, 6, and 24 h compared to baseline reading in both S and NAG groups. Also, the pulsatility index (PI) was statistically higher at 1, 6, and 24 h compared to baseline readings in S and NAG groups. There was no statistically significant difference regarding the need for EBP. Conclusions In terms of headache relief or the need for EBP, there is no difference between individual SPG block or combined SPG block and GONB in the treatment of PDPH. | ||||
