• Status: Unknown status
• Trial end date: 2017-12-01
• Target enrollment: 0
• Participant gender: All

Summary

Pre-operative anxiety leads to higher sympathetic stimulation. Propofol in the main drug used during interventional or imaging techniques that need sedation. Also, dexmedetomidine causes sedation, analgesia, sympatholytic properties, without respiratory depression.In stereotactic brain biopsy; patient discomfort due to drilling a hole through the skull and the advancement of the biopsy needle make the patient in need for good sedation and analgesia.
