What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time to Recovery of T1 to 10% of Baseline Value From Start of Rocuronium + Sugammadex or Succinylcholine Administration
Time Frame: Up to 15 minutes after administration of rocuronium + sugammadex or succinylcholine
Neuromuscular functioning was monitored by applying repetitive Train-Of-Four (TOF) electrical stimulations to the ulnar nerve every 15 seconds and assessing twitch response at the adductor pollicis muscle. T1 refers to the amplitude (height) of the first twitch after TOF nerve stimulation.
Up to 15 minutes after administration of rocuronium + sugammadex or succinylcholine

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Time to Recovery of T1 to 90% of Baseline Value From Start of Rocuronium + Sugammadex or Succinylcholine Administration
Time Frame: Up to 20 minutes after administration of rocuronium + sugammadex or succinylcholine
Neuromuscular functioning was monitored by applying repetitive TOF electrical stimulations to the ulnar nerve every 15 seconds and assessing twitch response at the adductor pollicis muscle. T1 refers to the amplitude (height) of the first twitch after TOF nerve stimulation.
Up to 20 minutes after administration of rocuronium + sugammadex or succinylcholine
Level of Consciousness: Number of Participants Awake and Oriented
Time Frame: Up to 24 hours after administration of rocuronium + sugammadex or succinylcholine
The number of participants who were awake and oriented was assessed as part of an overall assessment of the clinical level of consciousness. The clinical level of consciousness was used as a measure of recovery from neuromuscular blockade at two time points: prior to transfer to the recovery room after extubation and prior to discharge from the recovery room. Attempts were made to arouse participants every 15 minutes with mild prodding, mild shaking, and asking questions regarding name, location, and day of the week. The assessment ended once the participant was awake and fully orientated.
Up to 24 hours after administration of rocuronium + sugammadex or succinylcholine
Level of Consciousness: Number of Participants Arousable With Minimal Stimulation
Time Frame: Up to 24 hours after administration of rocuronium + sugammadex or succinylcholine
The number of participants aroused with minimal stimulation was assessed as part of an overall assessment of level of consciousness. The level of consciousness was used as a measure of recovery from neuromuscular blockade at two time points: prior to transfer to the recovery room after extubation and prior to discharge from the recovery room. Attempts were made to arouse participants every 15 minutes with mild prodding, mild shaking, and asking questions regarding name, location, and day of the week. The assessment ended once the participant was awake and fully orientated.
Up to 24 hours after administration of rocuronium + sugammadex or succinylcholine
Level of Consciousness: Number of Participants Responsive Only to Tactile Stimulation
Time Frame: Up to 24 hours after administration of rocuronium + sugammadex or succinylcholine
The number of participants responsive only to tactile stimulation was assessed as part of an overall assessment of the level of consciousness. The level of consciousness was used as a measure of recovery from neuromuscular blockade at two time points: prior to transfer to the recovery room after extubation and prior to discharge from the recovery room. Attempts were made to arouse participants every 15 minutes with mild prodding, mild shaking, and asking questions regarding name, location, and day of the week. The assessment ended once the participant was awake and fully orientated.
Up to 24 hours after administration of rocuronium + sugammadex or succinylcholine
Number of Participants Able to Perform 5-Second Head Lift
Time Frame: Up to 24 hours after administration of rocuronium + sugammadex or succinylcholine
The number of participants who were able to lift their head for 5 seconds was assessed as a measure of recovery following neuromuscular blockade at two time points: prior to transfer to the recovery room after extubation and prior to discharge from the recovery room. The assessment was performed every 15 minutes until the first successful 5-second head lift was achieved.
Up to 24 hours after administration of rocuronium + sugammadex or succinylcholine
Number of Participants Experiencing General Muscle Weakness
Time Frame: Up to 24 hours after administration of rocuronium + sugammadex or succinylcholine
The number of participants experiencing general muscle weakness was assessed by the investigator as a measure of recovery from neuromuscular blockade at two time points: prior to transfer to the recovery room after extubation and prior to discharge from the recovery room. The assessments were performed every 15 minutes until the absence of general muscle weakness. A standardized examination form was used to determine the presence or absence of muscle weakness in various muscle groups.
Up to 24 hours after administration of rocuronium + sugammadex or succinylcholine
