Summary

1. Observe the changes of TCD/TCCD spectrum shape before and after lumbar puncture in patients with severe neurological disease.
2. Discuss the TCD/TCCD spectrum shape and parameters of cerebral arteries and neurocritical patients Correlation of intracranial pressure.

Conditions

  • Intracranial Pressure Increase

Interventions

DEVICE

The morphology and parameters of cranial ultrasound spectrum based on cerebral artery

Subjects who meet the standards will undergo a full-body examination and basic life after entering the ICU Sign evaluation and monitoring, mainly including nervous system specialist physical examination, multi-modal brain function testing, Respiratory system monitoring and management, hemodynamic monitoring, APACHE Ⅱ score, GCS score, and routine general circulation, respiratory management, sedation and analgesia management, temperature management, infiltration Pressure management, lumbar pressure measurement The included subjects were monitored for optic nerve sheath diameter, TCD/TCCD before and after lumbar puncture, and recorded spectrum morphology: normal, high resistance state, ischemic topic, congestion state, spasticity, nail wave/oscillating wave state, S1S2 fusion high point state, and recording at the same time Parameters: systolic flow rate (Vs) Shu Tensile blood flow velocity (Vd), average blood flow velocity (Vm), pulsatility index (PI), impedance Index (RI)
