Description of intervention(s) / exposure
Acquisiton of additional data from patients who have elected to undergo a sphenopalatine block for the treatment of their postdural puncture headache. This involves additional assessments at 30mins, 1 hour and hourly until the return of gag reflex. It is anticipated that this will involve 3 assessments for most patients (30min, 1hr and 2hr)immeadiately post block performance. Each assessment lasts <5mins. Patients will be followed up the following day and the day after (day 1 and 2)-which will routinely occur as part of the management of patients suffering from a PDPH and at one week(phone review)-again which would happen to patients suffering from a PDPH. Again these assessments will last <5mins.

Outcomes
Primary outcome [1] 308311 0
Pain from headache score post block performance (scored x/10)

Timepoint [1] 308311 0
Primary outcome will be pain score from headache (scored x/10) one hour post block performance.
Secondary outcome [1] 354594 0
Presence/absence of gag reflex post block performance-assessed by clinical examination by eliciting a gag reflex on both the right and left side. ie clinical stimulation of gag by touching the posterior wall of the oropharynx with either a sterile swab or tongue depressor.
Timepoint [1] 354594 0
Alteration of gag reflex at 1 hour post block performance
Secondary outcome [2] 355151 0
Time to return of normal gag reflex-assessed as above. ie clinical stimulation of gag by touching the posterior wall of the oropharynx with either a sterile swab or tongue depressor.
Timepoint [2] 355151 0
Hourly assessment post block performance. Anticipated that all gag reflexes will be normal at 2 hours.
Secondary outcome [3] 355152 0
Requirement for epidural blood patch within 7 days
Timepoint [3] 355152 0
The performance of an epidural blood patch as assessed by phone follow up at 7 days post block performance.
Secondary outcome [4] 365479 0
Change in systolic blood pressure of >10% at 1 hour. Pre-block as assessed by the last blood pressure taken as part of routine ward care by ward nursing staff. Systolic blood pressure to be measured by ward staff 1 hour post block performance.
Timepoint [4] 365479 0
1 hour post block performance.
Secondary outcome [5] 365481 0
Patient requirement of opiates to treat the headache post block. Data collected from medication record.
Timepoint [5] 365481 0
Time interval between performance of the sphenopalatine block and day 1 post block review.

Summary
Brief summary
We are attempting to conduct a study examining the characteristics of the sphenopalatine block when used in the treatment of postdural puncture headaches-which is a not infrequent and expected complication of both spinal and epidural anaesthesia.
The sphenopalatine block is a relatively non-invasive alternative way of treating these headaches and is currently in use and offered as a therapeutic option at the Mater Mothers and Adults Brisbane.
The study aims to describe the physiological effects of this block . We plan on conducting our research by collecting additional information from patients that have elected to have this procedure as part of their treatment.
