简要总结

The purpose of this study is to determine the maximum ratio of the twitch amplitude (T1) to the reference twitch (Tref) amplitude (T1/Tref) that provides excellent intubating conditions.

入选标准

  • Age > or = 18 years old
  • Patients willing to participate and provide an integrated, informed consent

排除标准

  • Patients with disorders, such as stroke, carpal tunnel syndrome, broken wrist with nerve damage, Dupuytren contracture, or any similar wrist injury.
  • Patients with systemic neuromuscular diseases such as myasthenia gravis.
  • Patients with significant organ dysfunction that can significantly affect pharmacokinetics of neuromuscular blocking and reversal agents, i.e., severe renal impairment requiring dialysis or end-stage liver disease.
  • Patients requiring a rapid sequence induction for airway protection.
  • Patients deemed ineligible for surgery, including pregnancy (as determined by standard of care testing).

研究组 & 干预措施

T1/Tref <0.1

Experimental

Participants will be intubated once the ratio of the twitch amplitude to the reference twitch amplitude (T1/Tref) <0.1 (deeper level of block)

干预措施: Twitch amplitude <0.1 (Device)

T1/Tref <0.3

Experimental

Participants will be intubated once the ratio of the twitch amplitude to the reference twitch amplitude T1/Tref <0.3 (intermediate depth of block)

干预措施: Twitch amplitude <0.3 (Other)

T1/Tref <0.5

Experimental

Participants will be intubated once the ratio of the twitch amplitude to the reference twitch amplitude T1/Tref <0.5 (shallower level of block)

干预措施: Twitch amplitude <0.5 (Other)

结局指标

主要结局

Maximum T1/Tref ratio associated with excellent intubating conditions

时间窗: Baseline

The T1/Tref ratio that leads to the highest proportion of patients being intubated under excellent conditions: T1/Tref \<0.1, T1/Tref \<0.3, or T1/Tref \<0.5

次要结局

  • Time to reach specific neuromuscular block level from rocuronium administration to achieving T1/Tref <0.1(Baseline)
  • Time to reach specific neuromuscular block level from rocuronium administration to achieving T1/Tref <0.3(Baseline)
  • Time to reach specific neuromuscular block level from rocuronium administration to achieving T1/Tref <0.5(Baseline)
  • Proportion of patients with excellent intubating conditions at predefined T1/Tred threshold: <0.1(Baseline)
  • Proportion of patients with good intubating conditions at predefined T1/Tred threshold: <0.1(Baseline)
  • Proportion of patients with poor intubating conditions at predefined T1/Tred threshold: <0.1(Baseline)
  • Proportion of patients with excellent intubating conditions at predefined T1/Tred threshold: <0.3(Baseline)
  • Proportion of patients with good intubating conditions at predefined T1/Tred threshold: <0.3(Baseline)
  • Proportion of patients with poor intubating conditions at predefined T1/Tred threshold: <0.3(Baseline)
  • Proportion of patients with excellent intubating conditions at predefined T1/Tred threshold: <0.5(Baseline)
  • Proportion of patients with good intubating conditions at predefined T1/Tred threshold: <0.5(Baseline)
  • Proportion of patients with poor intubating conditions at predefined T1/Tred threshold: <0.5(Baseline)
