Brief Summary
Non-traumatic SAH, linked in 85% of cases to the rupture of an intracranial aneurysm, is a serious stroke affecting young people. Half of all survivors suffer cognitive impairment. The presentation is that of a sudden-onset, isolated headache. This population is exposed to headache during hospitalization, which lasts an average of 13 days. This length of hospitalization is due to the fact that these patients must be monitored during the potential vasospasm period that occurs between days 4 and 14 after SAH. The pain associated with SAH is a source of discomfort and increased morphine consumption during the ICU stay, particularly during the first 10 days. Current recommendations call for conventional pain management with a combination of tier 1, 2 and/or 3 analgesics. For headache control, opioids are widely prescribed, sometimes in high doses, with adverse effects, despite efforts to reduce their use. Maximum headache pain scores remain high, indicating inadequate pain management. This highlights the urgent need to study alternative opioid-sparing and analgesia strategies for patients with SAH.

Study Arms (2)
Control group
NO INTERVENTIONPain management according to the protocol in force in the neurosurgical intensive care unit (analgesics: Paracetamol, Nefopam and morphine PCA).
Sphenopalatine Ganglion Block using 2% lidocaine
EXPERIMENTALAddition of (BGSP) Sphenopalatine ganglion block with Lidocaine 2% Injectable Solution (2mg/ml) 1.5ml \* 3 consecutive times maximum if EN \>3/10, to be repeated every 12h for 7 days if necessary. BGSP performed by the department's Ides after training by the anesthetists.
Interventions
A hollow-stem swab soaked in viscous Xylocaine is inserted into the patient's nasal cavity (one swab per nostril) until it stops. 1.5ml Lidocaine 20% (20mg/ml) is injected into each swab using a 5ml syringe and a pink trocar. Both swabs are left in place for 10 min.
Eligibility Criteria
You may qualify if:
- ≥ 18 years
- Non-traumatic SAH with or without aneurysm on brain imaging
- WFNS score 1 and 2
- Patient awake and extubated after radiological procedure
- Patient in pain (EN \> 3/10) despite usual level 1 analgesics (Paracetamol + Acupan)
- Affiliated with or benefiting from a social security scheme
You may not qualify if:
- Contraindication to sphenopalatine ganglion block (deviated nasal septum, repeated epistaxis, allergy to Lidocaine)
- Patient unable to assess pain by EN
- Persons covered by Articles L1121-5 to L1121-8 of the CSP and Articles 31 to 35 of Regulation 536/2014.
- Participation in other interventional research
- Patient's refusal to participate
- Arteriography more than 48 hours old
- Inaugural headache lasting more than 48 hours
- Presence of an unsecured vascular malformation at high risk of rupture
