Dexmedetomidine on Optic Nerve Sheath Diameter

• Status: Withdrawn
• Trial end date: 2018-04-01
• Target enrollment: 0
• Participant gender: All

Summary

Dexmedetomidine, might attenuate the sympathetic activation and contribute to stable hemodynamics. The investigator hypothesized that continuous infusion of dexmedetomidine during laparoscopic lower abdominal surgery, might help to attenuate the increment of intracranial pressure and the investigator would observe the optic nerve sheath diameter using ultrasonography.
