NCT01898819

Brief Summary

Intraocular pressure is significantly increase during robot-assisted laparoscopic radical prostatectomy which is performed in a steep trendelenburg position at prolonged timeds of pneumoperitoneum. Threrefore we decided to evaluate the effect of dexmedetomidine in intraocular pressure during roboti-assisted laparoscopic radical prostatectomy.

Outcome Measures

Primary Outcomes (1)

  • Influence of dexmedetomidine in intraocular pressure during robot-assisted laparoscopic prostatectomy.

    T0: Pre-induciton T1: 5min after anesthesia induction T2: 5 min after establish pneumoperitoneum T3: 15min after steep trendelenburg position T4: 30min after steep trendelenburg position T5: 45min after steep trendelenburg T6: 60min after steep trendelenburg T7: 75min after steep trendelenburg T8: 5min after returning to horizontal position T9: operation end T10: 5min after tracheal extubation T11: 60min after tracheal extubation

    change of intraocular pressure from T0 to T11 for 60mins
