NCT01728584

Brief Summary

The purpose of this pilot study is to compare the use of deep or standard neuromuscular blockade (NMB) in combination with low or standard insufflation pressure in participants undergoing a surgical procedure, laparoscopic cholecystectomy. Insufflation refers to the injection of carbon dioxide into the abdomen during the laparoscopic surgery, to allow visualization of and access to the surgical field. The primary hypothesis of the study is that the use of sustained deep NMB improves the surgeon's overall satisfaction with surgical conditions as compared to standard NMB. The in-patient surgery is performed on Day 1 and the participant remains hospitalized for at least 48 hours following the surgery (or at least 24 hours following the surgery, if local practice does not allow 48 hours of hospitalization post surgery). On Day 8, a follow-up visit/contact including all participants occurs.

Outcome Measures

Primary Outcomes (2)

  • Score on Surgeon's Assessment of Overall Satisfaction With the Surgical Conditions: By Depth of NMB (Standard, Deep) and Insufflation Pressure (Standard, Low)

    At the end of the procedure the surgeon responds to the following question, using an 11-point scale from 0 (poor, needed intervention) to 10 (excellent): "How satisfied were you overall with the surgical conditions related to anesthesia and pneumoperitoneum during the surgery you just performed?" If at any time the surgeon requests a rescue intervention, the overall assessment of surgical conditions should be rated as 0 (=poor, needed intervention). The surgeon will rate the surgical conditions according to his opinion but if a rescue intervention has been applied, that individual participant will be counted with a score of zero in the analysis.

    End of surgery (Day 1)

  • Score on Surgeon's Assessment of Overall Satisfaction With the Surgical Conditions: By Treatment Arm

    At the end of the procedure the surgeon responds to the following question, using an 11-point scale from 0 (poor, needed intervention) to 10 (excellent): "How satisfied were you overall with the surgical conditions related to anesthesia and pneumoperitoneum during the surgery you just performed?" If at any time the surgeon requests a rescue intervention, the overall assessment of surgical conditions should be rated as 0 (=poor, needed intervention). The surgeon will rate the surgical conditions according to his opinion but if a rescue intervention has been applied, that individual participant will be counted with a score of zero in the analysis.

    End of surgery (Day 1)

Secondary Outcomes (12)

  • Participant's Overall Average Pain Score in the First 24 Hours After Administration of Sugammadex: By Depth of NMB (Standard, Deep) and Insufflation Pressure (Standard, Low)

    Up to 24 hours after administration of sugammadex on Day 1

  • Participant's Overall Average Pain Score in the First 24 Hours After Administration of Sugammadex: By Treatment Arm

    Up to 24 hours after administration of sugammadex on Day 1

  • Score on Surgeon's Assessment of Overall Satisfaction With the Visibility of the Surgical Field: By Depth of NMB (Standard, Deep)

    End of surgery (Day 1)

  • Score on Surgeon's Assessment of the Overall Adequacy of Muscle Relaxation During Surgery: By Depth of NMB (Standard, Deep)

    End of surgery (Day 1)

  • Score on Surgeon's Assessment of the Overall Adequacy of Insufflation Pressure During Surgery: By Depth of NMB (Standard, Deep)

    End of surgery (Day 1)

Study Arms (4)

Standard NMB and Standard Insufflation Pressure

EXPERIMENTAL

Treatment condition for this arm is Standard NMB (depth of blockade at a targeted Train of Four \[TOF\] ratio of 10%)/Standard insufflation pressure (starting pressure of 12 mmHg).

Drug: RocuroniumOther: InsufflationDrug: Sugammadex

Standard NMB and Low Insufflation Pressure

EXPERIMENTAL

Treatment condition for this arm is Standard NMB (depth of blockade at a targeted TOF ratio of 10%)/Low insufflation pressure (starting pressure of 8 mmHg).

Drug: RocuroniumOther: InsufflationDrug: Sugammadex

Deep NMB and Standard Insufflation Pressure

EXPERIMENTAL

Treatment condition for this arm is Deep NMB (depth of blockade of 1-2 PTCs)/Standard insufflation pressure (starting pressure of 12 mmHg).

Drug: RocuroniumOther: InsufflationDrug: Sugammadex

Deep NMB and Low Insufflation Pressure

EXPERIMENTAL

Treatment condition for this arm is Deep NMB (depth of blockade of 1-2 PTCs)/Low insufflation pressure (starting pressure of 8 mmHg).

Drug: RocuroniumOther: InsufflationDrug: Sugammadex

Interventions

NMB will be induced by intravenous (IV) administration of a bolus dose of 0.45 mg/kg rocuronium. NMB will be maintained using rocuronium infusion or additional bolus doses as needed for the management of NMB to the targeted depth according to the assigned treatment condition. - Standard NMB - administration of neuromuscular blocking agent (NMBA) titrated to a depth of blockade at a targeted TOF ratio of 10% (range: TOF count 2-3 to TOF ratio of 20%). - Deep NMB - administration of NMBA titrated to a targeted depth of 1-2 Post Tetanic Counts (PTCs) (range: 1-5 PTC).

Insufflation (injection) of carbon dioxide will be used to induce pneumoperitoneum, which is presence of air or gas in the abdominal (peritoneal) cavity. * Standard insufflation pressure - a starting pressure of 12 mmHg will be used. * Low insufflation pressure - a starting pressure of 8 mmHg will be used.
