Keywords
Transcranial Doppler（TCD）,Intracranial pressure(ICP)
Brief 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.
Detailed description
After entering the ICU, the subjects who meet the standards will undergo a full-body physical examination and basic vital signs assessment and monitoring, which mainly include specialized examinations of the nervous system, multimodal brain function testing, respiratory system monitoring and management, hemodynamic monitoring, and APACHEⅡ Score, GCS score, and perform routine general circulation, breathing management, sedation and analgesia management, temperature management, osmotic pressure management, lumbar puncture pressure measurement
Interventions
DEVICEThe 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)

| Measure | Time frame | Description |
|---|---|---|
| The TCD/TCCD spectrum shape and parameters of cerebral arteries are related to the intracranial pressure of neurocritical patients | January 26, 2021 to December 30, 2022 | The change of TCD/TCCD spectrum shape can qualitatively evaluate ICP. The intracranial pressure is qualitatively determined by spectrum morphology to help clinicians quickly assess intracranial pressure and guide treatment. Accurately identify the normal shape of the spectrum, the state of high resistance, the state of ischemia, the state of congestion, the state of spasticity, the state of nail wave/oscillating wave, and the state of S1S2 fusion high tip. Discuss the correlation between spectrum shape and waist piercing ICP. |
