NCT07274683

Brief Summary

The goal of this clinical trial is to learn about the effect of preoperative administration of stellate ganglion block on postoperative sleep status in patients with prolonged disorders of consciousness. The main aims to answer are: • To explore the effect of preoperative administration of stellate ganglion block on postoperative polysomnography and total sleep time in patients with prolonged disorders of consciousness. • To explore the effect of preoperative administration of stellate ganglion block on postoperative cerebral oxygen saturation, cerebral hemodynamic parameters and recovery of consciousness. Participants will be pDoC patients with intact skulls after acquired brain injury who will undergo spinal cord electronic stimulator implantation under general anesthesia at Beijing Tiantan Hospital. Stellate ganglion block will be administrated before the surgery. Polysomnography, total sleep time, cerebral oxygen saturation, cerebral hemodynamic parameters, CRS-R scores, GCS scores, WHIM scores and NCS scores will be investigated.

stellate ganglion block

preoperative administration of stellate ganglion block

Drug: stellate ganglion block with 0.5% ropivacaine

Interventions

A single dose of ultrasound-guided stellate ganglion block with 0.5% ropivacaine was administered to the pDoC patients after induction of general anesthesia but before surgical incision.
