Brief Summary

The use of low-pressure pneumoperitoneum seems to be able to reduce complications such as postoperative pain. However, the quality of evidence for most studies evaluating this relationship is considered low. The absence of concealment of pneumoperitoneum pressure and the lack of description of neuromuscular blockade characteristics are the main causes of bias. The purpose of this study will be to evaluate by means of a prospective, randomized and double-blinded trial, the quality of recovery (QoR-15) questionnaire of patients undergoing laparoscopic cholecystectomy under moderate neuromuscular blockade, using low pneumoperitoneum pressure or "standard" pressure. Eighty patients submitted to laparoscopic cholecystectomy and randomly distributed in two groups will be included: low pneumoperitoneum pressure (10 mmHg) or "standard" pressure (14 mmHg). The value of abdominal pressure will be kept hidden for all participants, except for the nurse responsible for the operating room. Moderate neuromuscular blockade will be maintained according to Train-of-four count (TOFc) = 3 for all cases.

Outcome Measures

Primary Outcomes (1)

  • Quality of recovery

    The quality of recovery will be assessed using the Qualtity of Recovery 15 questionnaire. Total scores range from 0 to 150. Higher scores mean a better outcome.

    From randomization up to 15 days

Secondary Outcomes (1)

  • Postoperative pain

    From the PACU arriving up to 24 hours

Study Arms (2)

Group pneumoperitoneum pressure 10

ACTIVE COMPARATOR

Pneumoperitoneum pressure at 10 mmHg

Drug: Pneumoperitoneum pressure 10 mmHg

Group neumoperitoneum pressure 14

PLACEBO COMPARATOR

Pneumoperitoneum pressure at 10 mmHg

Drug: Pneumoperitoneum pressure 14 mmHg

Interventions

The abdomen will be inflated with carbon dioxide to maintain the intra-abdominal pressure at 10 mmHg (group 10)

Group pneumoperitoneum pressure 10

The abdomen will be inflated with carbon dioxide to maintain the intra-abdominal pressure at 14 mmHg (group 14).

Group neumoperitoneum pressure 14
