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.

Outcome Measures

Primary Outcomes (1)

  • Demonstrate a 50% change in morphine consumption with sphenopalatine ganglion block during the first 72 hours after cerebral arteriography

    Total morphine consumption in mg in the first 72 hours after cerebral arteriography in the Intensive care (ICU)

    during 72 hours

Secondary Outcomes (7)

    during 7 days

  • Describe morphine consumption per day during the patient's hospitalization for the 2 groups

    during hospitalization or 10 days

  • Describe the complications associated with sphenopalatine ganglion block.

    during 7 days

  • Evaluate the feasibility of the (BGSP) sphenopalatine ganglion block act performed by Ides

    during 7 days

  • Demonstrate that the sphenopalatine ganglion block strategy changes headaches at 28 days.

    at 28 days

  • +2 more secondary outcomes

Study Arms (2)

Control group

NO INTERVENTION

Pain 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

EXPERIMENTAL

Addition 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.
