NCT01930747

Brief Summary

The objective of this study is to compare the value of deep neuromuscular block (NMB) (using rocuronium) in laparoscopy versus high dose opioids (using remifentanil) or 1 minimum alveolar concentration (MAC) inhalation (using sevoflurane) for the surgeon. The study hypothesis is that laparoscopic workspace is larger when using rocuronium versus opioids or inhalation. Laparoscopic workspace is measured as the abdominal compliance and the pressure at volume zero (PV0) using the abdominal pressure volume relation. Three points allow to calculate the abdominal compliance and the pressure at zero volume (PV0).

Outcome Measures

Primary Outcomes (2)

  • Effect of Anesthetics on the Pressure at Zero Volume (PV0) Measured During Insufflation of the Abdomen

    the impact of the following agents on the pressure at zero volume (PV0): remifentanyl \> 0.50 µg/kg/min; sevoflurane 1 MAC and deep neuromuscular block (rocuronium given with PTC \< 4).

    5 min after reaching 1 MAC or haven given the anesthetics intravenous

  • Effect of Anesthetics on the Abdominal Elastance (E) Measured During Insufflation of the Abdomen by

    the impact of the following agents on the abdominal elastance (E) : remifentanyl \> 0.50 µg/kg/min; sevoflurane 1 MAC and deep neuromuscular block (rocuronium given with PTC \< 4).

    5 min after reaching 1 MAC or haven given the anesthetics intravenous

Secondary Outcomes (1)

  • Adverse Events Difference Between the Three Groups

    from zero till 24 hours after recovery of surgery.

Eligibility Criteria

Age18 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • \. Laparoscopic bariatric surgery in a patient older than 18 years of age without previous laparotomy. Examples of laparoscopic bariatric procedures are gastric band, sleeve gastrectomy, gastric bypass, gastric bypass after lap band, and revision of a gastric bypass

You may not qualify if:

  • Allergies or contraindications to the use of one or more of the following drugs: propofol, rocuronium, sugammadex, remifentanyl, or sevoflurane
  • History of a laparotomy
  • Emergency laparoscopy
