Conditions: Cholecystectomy, Laparoscopic
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 49
Healthy volunteers: no

Brief summary:
The purpose of this investigation is to compare the surgical conditions during laparoscopic cholecystectomy at a low intra-abdominal pressure with deep or moderate muscle relaxation.

The primary hypothesis is that surgical conditions during laparoscopic cholecystectomy are better with deep muscle relaxation than moderate muscle relaxation.

Detailed description:
The purpose of this investigation is to compare the surgical conditions with two degrees of neuromuscular blockade in patients who have laparoscopic cholecystectomy done with pneumoperitoneum 8 mmHg.

Arms:
arm 1: None arm 2: None

Interventions: intervention 1: Rocuronium intervention 2: Rocuronium
