Stellate Ganglion Block and Prognosis of Neurological Function After Subarachnoid Hemorrhage

Condition(s) studied

Investigational drug(s) / intervention(s)

Intervention group: Prior to the initiation of surgery, a single ultrasound-guided stellate ganglion block was performed on the ipsilateral side of the lesion.The dose and concentration of local anesthesia: 0.5% ropivacaine 5-10ml. Criteria for successful block: the patient developed Horner's syndrome, characterized by miosis, ptosis, eyeball caved in, nasal congestion, conjunctival congestion, reddish face and no sweat on the face

Study summary

The incidence of cerebral vasospasm after aneurysm subarachnoid hemorrhage (aSAH) is as high as 70%; cerebral vasospasm（CVS） is closely related to delayed cerebral ischemia （DCI）, which is one of the important reasons for poor outcomes in patients with aSAH.

In recent years, it has been reported that stellate ganglion block(SGB) can effectively alleviate cerebral vasospasm(CVS), reduce cerebral blood flow velocity and increase cerebral perfusion in patients with aneurysm subarachnoid hemorrhage(aSAH)。However, whether the alleviation of CVS after SGB is beneficial to the long-term neurological prognosis has not been confirmed Therefore, a prospective randomized controlled study is needed to further explore the role of SGB block in improving the outcomes of patients with aSAH.

Eligibility

Primary outcome measure(s)

• The modified Rankin Scale (mRS) scores at 90 days — 90 days postoperatively
  The modified Rankin Scale (mRS) is used to evaluate the primary outcome. The scale of mRS is 0 to 6. The best neurological outcome is the mRS with 0, indicating no any symptom left. mRS of 6 is the worst, indicating death. mRS will be evaluated by outcomes assessor who is blinded to the grouping.
