Sugammadex: Effect on the Awareness Monitoring and Hemodynamics

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified June 2012 by University of Athens.

Sugammadex is used to reverse the neuromuscular blocking effect of steroid neuromuscular blockers. Its cardiovascular effects and effect on brain cortex, if any, may be associated to the reversal of the neuromuscular block. The aim of the study was to investigate the pure effects of sugammadex in the absence of the agonist.

Condition Intervention
Surgical Procedure, Unspecified
Drug: sugammadex
Drug: Sugammadex 4 mg/kg
Drug: Sugammadex 16mg/kg

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)

Study Start Date: December 2010
Estimated Primary Completion Date: February 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: sugammadex 2 mg/kg
2 mg/kg of sugammadex are given when a response of two counts of train of four are present
Drug: sugammadex
Sugammadex 2 mg/kg when a two count of train of four appears
Active Comparator: 4 mg/kg of sugammadex
4 mg/kg of sugammadex are given when a posttetanic count 1-3 appears
Drug: Sugammadex 4 mg/kg
Sugammadex 4 mg/kg are given when a posttetanic count 1-3 appears
Active Comparator: Sugammadex 16 mg/kg
Sugammadex 16 mg/kg are given three minutes after the injection of cis-atracurium
Drug: Sugammadex 16mg/kg
Sugammadex 16 mg/kg three minutes after the injection of cis-atracurium

Detailed Description:

Three groups of patients undergoing elective major surgery and given cis-atracurium for muscle relaxation are studied.

Group 1 receives 2 mg/kg of sugammadex when a count of two of the train of four appears Group 2 receives 4 mg/kg of sugammadex when a posttetanic count 1-3 appears Group 3 receives 16 mg/kg of sugammadex three minutes after administration of cis-atracurium.

Heart rate, arterial blood pressure, oxygen saturation, end-tidal CO2, entropy and bispectral index are recorded every three minutes
