Conditions

Robot-Assisted Laparoscopic Radical Prostatectomy

Keywords

deep neuromuscular blockade, intraocular pressure

Brief summary

Intraocular pressure is significantly increase during robot-assisted laparoscopic radical prostatectomy which is performed in a steep trendelenburg position at prolonged times of pneumoperitoneum. Therefore investigators decided to evaluate the impacts of surgical visibility through deep neuromuscular blockade on intraocular pressure in patients undergoing Robot-Assisted Laparoscopic Radical Prostatectomy.

Interventions

deep neuromuscular blockade using rocuronium and reverse with sugammadex

moderate neuromuscular blockade using atracurium and reverse with neostigmine
