Brief Summary
Posttraumatic Subarachnoid hemorrhage (SAH) is a life-threatening neurological problem with a high mortality rate. Delayed cerebral ischemia (DCI) is the second-leading cause of death and disability in patients suffering from SAH. DCI is strongly associated with cerebral arterial vasospasm (CAV), which reduces cerebral blood flow (CBF) and causes cerebral infarction. Various treatment modalities have been tried for the prevention and treatment of vasospasm, including oral nimodipine and isovolumic hypertension, as well as endovascular treatments such as intra-arterial drug infusion and balloon angioplasty. A few studies have demonstrated the role of stellate ganglion block (SGB) in the management of this dreaded complication. Cervical sympathetic block (CSB) may be an effective therapy but is not routinely performed to treat vasospasm/DCI. CSB is a local, minimally invasive, low cost and safe technique that can be performed at the bedside and may offer significant advantages as complementary treatment in combination with more conventional neurointerventional surgery interventions. Aim of study is evaluating the effect of superior sympathetic ganglion block versus stellate ganglion block in treating cerebral vasospasm and prevention of delayed cerebral ischemia in refractory post-traumatic subarachnoid hemorrhage.

Interventions
5 ml bupivacaine 0.5% will be injected between the common carotid artery and longus capitis muscle at the level of C7 vertebra
5 ml bupivacaine 0.5% will be injected around the internal carotid artery at the level of carotid bifurcation
Eligibility Criteria
You may qualify if:
- Trauma patient with radiological evidence of refractory SAH despite adequate pharmacological treatment; TCD velocity \> 120 cm/sec.
- Trauma Patients with clinicoradiological evidence of cerebral vasospasm. The clinical criteria is new onset of neurological impairment such as hemiparesis, aphasia, hemianopia, or decrease of at least 2 points on the GCS not explained by appearance of new finding in follow up CT.
- Age 18-65 will be included in the study
- Both sex are included .
You may not qualify if:
- Refusal to consent participating research from patient or his guardian.
- Patients with deterioration in the level of consciousness due to other causes such as rebleeding, infarct, hydrocephalus, cerebral edema, infection, electrolyte disorder, or seizure.
- Trauma and local infection in the nerve block area.
- Coagulopathy.
