Study summary

The aim of this study is to evaluate whether the use of Sugammadex for reversing the neuromuscular blocking effects of rocuronium during neurointerventional procedures can speed recovery of neuromuscular function. Half of participates will receive Neostigmine with glycopyrrolate, while the other half will receive Sugammadex.

Read the detailed description

Incomplete recovery from neuromuscular blocking agents (NMBAs) residual block after anesthesia and surgery continues to be a common problem in the postanesthesia care (PACU).

Neostigmine remains the most common acetylcholinesterase inhibitor in the United States. However, administration of the drug significantly impairs genioglossus muscle activity when administered after full recovery from neuromuscular block. Moreover, doses of neostigmine exceeding 0.06 mg/kg increase the risk of respiratory complications independent of NMBAs effects.

Sugammadex is a modified γ-cyclodextrin that rapidly reverses that effect of the steroidal nondepolarizing NMBAs rocuronium and vecuronium. Sugammadex forms a stable, inactive 1:1 complex with rocuronium or vecuronium, reducing the amount of free NMBA available to bind to nicotinic acetylcholine receptors at the neuromuscular junction. Unlike neostigmine, sugammadex completely reverses even dense neuromuscular blocks.

Patients having catheter-based neurointerventional procedures are kept deeply anesthetized. It is common to find patients nearly completely paralyzed at the end of neurointerventional procedures and have a markedly delayed emergence while waiting for muscle function to recover sufficiently to safely antagonize with neostigmine.

What researchers measure

Primary outcomes

  1. Time in Minutes to Reach Train of Four (TOF) Ratio ≥ 0.9 After the Administration of Reversal Agent

    The primary outcome was a time-to-TOF ratio ≥ 0.9 after the administration of the reversal agent. The TOF ratio was measured in a continuous manner every 12 seconds from the administration of the reversal drug until TOF ratio ≥ 0.9 or until 90 minutes after administration of the reversal agent.

    Time frame: within 90 minutes after endotracheal extubation

  2. TOF Ratio at 90 Min

    TOF (train of four), also known as a peripheral nerve stimulator, is used to assess nerve function in patients receiving neuromuscular blocking agents (paralytic medications). Before giving the medications, the baseline must be measured because this tells how much electrical stimulation the patient needs for nerve stimulation without any paralytic on board. Our primary outcome TOF ratio between TOF at 90 minutes after the administration of the reversal agent versus the TOF at baseline tells us how well the treatment is working to reverse the rocuronium Neuromuscular. This is a sensitivity analysis of primary analysis.

    Time frame: at 90 minutes after the administration of the reversal agent

Secondary outcomes

  1. The Time for Extubation After Administration of Reversal Agents

    Time from administration of reversal agent to tracheal extubation

    Time frame: Up to 4 hours after administration of reversal agents

  2. Change of Diaphragmatic Contractility Speed- Sniff (Breathing From the Nose), cm/s

    The change of diaphragmatic contractility speed was defined as baseline minus postoperative diaphragmatic contraction.

    Time frame: from baseline to 90 minutes after the administration of the reversal agent

  3. Change of Diaphragmatic Contractility Speed, Deep Breathing From Mouth, cm/s

    The change of diaphragmatic contractility speed was defined as baseline minus postoperative diaphragmatic contraction.

    Time frame: from baseline to 90 minutes after the administration of reversal agent

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 16, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
