NCT03828032

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.

Procedure: Mannitol injection

Hypertonic saline injection

EXPERIMENTAL

The participant receive hypertonic saline of specific concentration injection to decrease intracranial pressure in the ward with optical probes on his/her forehead.

Procedure: Hypertonic saline injection

Interventions
