Multi-parameters'Change Process During Dehydration Therapy on Brain Edema Patients.

Not Applicable

• Conditions: Water on the Brain; Hemodynamic Instability; Intracranial Pressure Increase

• Registration Number: NCT03828032
• Lead Sponsor: Ting Li

Brief Summary

This study aims to investigate the inner mechanism during different dehydration therapies such as mannitol injection and hypertonic saline. The investigators used a self-made near infrared spectroscopy (NIRS) instrument to monitor the physiological changes noninvasively including oxyhemoglobin (\[HbO2\]), deoxy-hemoglobin (\[Hb\]), the derived change in blood volume (\[tHb\]) and water concentration on the forehead of brain edema patients.

Detailed Description

Cerebral edema, as an acute head injury along with high intracranial pressure, has been of great interest over decades in clinical neurosurgery research. Dehydration therapy is a common clinical method to decrease intracranial pressure. This study aims to investigate the inner mechanism during different dehydration therapies such as mannitol injection and hypertonic saline. The investigators used a self-made near infrared spectroscopy (NIRS) instrument to monitor the physiological changes noninvasively including oxyhemoglobin (\[HbO2\]), deoxy-hemoglobin (\[Hb\]), the derived change in blood volume (\[tHb\]) and water concentration on the forehead of brain edema patients. Then the investigators compared the changes process of multiple physiological parameters during different dehydration therapies.
