A multi-center, randomized, parallel group, comparative, active controlled, safety assessor blinded trial in adult subjects comparing rocuronium plus sugammadex versus succinylcholine alone in subjects undergoing short surgical procedures in out-patient surgicenters. The primary objective was to evaluate changes in plasma potassium levels after treatment with rocuronium, sugammadex, or succinylcholine in adult subjects scheduled for short surgical procedures in out-patient surgicenters.

Treatment and study plan

Rocuronium

Drug

A single bolus intubation dose of 0.6 mg/kg rocuronium will be administered following induction of anesthesia and if required, single bolus dose(s) of 0.15 mg/kg rocuronium will be administered to maintain the neuromuscular block.

Other names: Zemuron® Injection (rocuronium bromide)

Sugammadex

Drug

At the end of the surgical procedure at a target depth of neuromuscular blockade of at least 1-2 Post-Tetanic Count (PTC), 4.0 mg/kg of sugammadex will be administered.

Other names: sugammadex sodium injection, SCH 900916, Org 25969, Bridion

Succinylcholine

Drug

A single bolus intubation dose of 1.0 mg/kg succinylcholine will be administered following induction of anesthesia and the subject is allowed to recover spontaneously from the neuromuscular blockade.

Other names: Quelicin® (succinylcholine chloride injection United States Pharmacopeia [USP])

Primary outcomes

  1. Change From Baseline in Plasma Potassium Levels at 5 Minutes After Treatment With Rocuronium or Succinylcholine

    Time frame: Baseline and 5 minutes post dose

    Change from baseline = 5 minutes post dose value - baseline value. Baseline levels were obtained prior to rocuronium or succinylcholine dose. Only data post rocuronium dose are included for "rocuronium - sugammadex" group. The change from baseline interval included most or all of the intubation/surgical period for sugammadex analysis (since sugammadex was administered at the end of the surgical procedure) but not for succinylcholine or rocuronium analyses (since these were administered immediately after the baseline measurement just prior to intubation/commencement of the surgical period).

  2. Change From Baseline in Plasma Potassium Levels at 5 Minutes After Treatment With Sugammadex

    Time frame: Baseline and 5 minutes post dose

    Change from baseline = 5 minutes post dose value - baseline value. Baseline levels were obtained prior to rocuronium dose. Only data post sugammadex dose are included for "rocuronium - sugammadex" group. The change from baseline interval included most or all of the intubation/surgical period for sugammadex analysis (since sugammadex was administered at the end of the surgical procedure) but not for succinylcholine or rocuronium analyses (since these were administered immediately after the baseline measurement just prior to intubation/commencement of the surgical period).

Secondary outcomes

  1. Change From Baseline in Plasma Potassium Levels at 2 Minutes After Treatment With Rocuronium or Succinylcholine

Only data post rocuronium dose are included for "rocuronium - sugammadex" group. The change from baseline interval included most or all of the intubation/surgical period for sugammadex analysis (since sugammadex was administered at the end of the surgical procedure) but not for succinylcholine or rocuronium analyses (since these were administered immediately after the baseline measurement just prior to intubation/commencement of the surgical period).

  2. Change From Baseline in Plasma Potassium Levels at 2 Minutes After Treatment With Sugammadex

    Time frame: Baseline and 2 minutes post dose

    Change from baseline = 2 minutes post dose value - baseline value. Baseline levels were obtained prior to rocuronium dose. Only data post sugammadex dose are included for "rocuronium - sugammadex" group. The change from baseline interval included most or all of the intubation/surgical period for sugammadex analysis (since sugammadex was administered at the end of the surgical procedure) but not for succinylcholine or rocuronium analyses (since these were administered immediately after the baseline measurement just prior to intubation/commencement of the surgical period).

  3. Change From Baseline in Plasma Potassium Levels at 10 Minutes After Treatment With Rocuronium or Succinylcholine

    Time frame: Baseline and 10 minutes post dose

    Change from baseline = 10 minutes post dose value - baseline value. Baseline levels were obtained prior to rocuronium or succinylcholine dose. Only data post rocuronium dose are included for "rocuronium - sugammadex" group. The change from baseline interval included most or all of the intubation/surgical period for sugammadex analysis (since sugammadex was administered at the end of the surgical procedure) but not for succinylcholine or rocuronium analyses (since these were administered immediately after the baseline measurement just prior to intubation/commencement of the surgical period).

  4. Change From Baseline in Plasma Potassium Levels at 10 Minutes After Treatment With Sugammadex

    Time frame: Baseline and 10 minutes post dose

    Change from baseline = 10 minutes post dose value - baseline value. Baseline levels were obtained prior to rocuronium dose. Only data post sugammadex dose are included for "rocuronium - sugammadex" group. The change from baseline interval included most or all of the intubation/surgical period for sugammadex analysis (since sugammadex was administered at the end of the surgical procedure) but not for succinylcholine or rocuronium analyses (since these were administered immediately after the baseline measurement just prior to intubation/commencement of the surgical period).

  5. Change From Baseline in Plasma Potassium Levels at 15 Minutes After Treatment With Rocuronium or Succinylcholine

    Time frame: Baseline and 15 minutes post dose

    Change from baseline = 15 minutes post dose value - baseline value. Baseline levels were obtained prior to rocuronium or succinylcholine dose.

    Change from baseline = 15 minutes post dose value - baseline value. Baseline levels were obtained prior to rocuronium dose. Only data post sugammadex dose are included for "rocuronium - sugammadex" group. The change from baseline interval included most or all of the intubation/surgical period for sugammadex analysis (since sugammadex was administered at the end of the surgical procedure) but not for succinylcholine or rocuronium analyses (since these were administered immediately after the baseline measurement just prior to intubation/commencement of the surgical period).

  7. Number of Participants With at Least One Adverse Event (AE) in Rocuronium - Sugammadex and Succinylcholine Treatment Groups

    Time frame: Up to 7 days post dose

    Only AEs which occurred following administration of sugammadex or succinylcholine are included. AEs in the rocuronium - sugammadex group occurring after rocuronium but before sugammadex administration are considered "pretreatment" events and are not included. The AE reporting interval included the entire intubation/surgical period for the succinylcholine group (since succinylcholine was administered just prior to intubation/commencement of surgery) but not for the rocuronium - sugammadex group (since sugammadex was administered at the end of the surgical procedure).

  8. Time to Recovery of the Fourth Twitch/First Twitch (T4/T1) Ratio to 0.9 Following Administration of 4.0 mg/kg of Sugammadex After Neuromuscular Blockade Induced by Rocuronium

    Time frame: Start of administration of sugammadex to recovery from neuromuscular blockade (Up to approximately 6 minutes)

    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. Nerve stimulation continued until the ratio of the magnitude of the fourth twitch (T4) to first twitch (T1) reached at least 0.9. The greater the T4/T1 ratio the greater the recovery from neuromuscular blockade, with a value of 1.0 representing full recovery.

  9. Time to Recovery of T1 to 90% of Baseline Following Neuromuscular Blockade Induced by Succinylcholine

    Time frame: Start of administration of succinylcholine to recovery from neuromuscular blockade (Up to approximately 18 minutes)

    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. Nerve stimulation continued until recovery of T1 of 90% of baseline and full recovery of neuromuscular function occurred as determined by the anesthesiologist as per routine clinical practice.
