Comparison of Intubation Conditions During Rapid Sequence Induction Obtained With Modified Time Principal Induction With a Standard Intubation Dose of Rocuronium Versus Succinylcholine

Phase 4
Recruiting
Conditions
Anesthesia
Interventions
Drug: Modified Time Principle Induction (MTPI) with rocuronium
Registration Number
NCT06029049
Lead Sponsor
The University of Texas Health Science Center, Houston
Brief Summary

The purpose of this study is to assess and compare conditions for tracheal intubation obtained with modified time principal induction with 0.6 mg/kg rocuronium and 1 mg/kg succinylcholine. Specifically, the investigators will be evaluating ease of laryngoscopy, vocal cord view, vocal cord opening, and movement of limbs and coughing during tracheal intubation in order to assess intubation conditions, to compare efficiency and success rate of tracheal intubation between two induction agents and to determine the rate of patient awareness during induction and post-operative recall of paralysis.

Primary Outcome Measures
NameTimeMethod
Ease of laryngoscopyDuring procedure (Between laryngoscope insertion to onset of ventilation (less than 7 minutes))

Ease of laryngoscopy is scored categorically as easy (Jaw relaxed, no resistance to blade during laryngoscopy) , fair (Jaw not fully relaxed, some resistance to blade) or difficult (Poor jaw relaxation, active resistance by patient to laryngoscopy)

Position of vocal cordsDuring procedure (Between laryngoscope insertion to onset of ventilation (less than 7 minutes))

Position of vocal cords is scored categorically as abducted, intermediate or closed

Movement of vocal cordsDuring procedure (Between laryngoscope insertion to onset of ventilation (less than 7 minutes))

Movement of vocal cords is scored categorically as none , moving or closing

Number of participants who moved their limbs during intubationDuring procedure (Between laryngoscope insertion to onset of ventilation (less than 7 minutes))

none, slight or vigorous

number of participants who coughed during tracheal intubationDuring procedure (Between laryngoscope insertion to onset of ventilation (less than 7 minutes))

none, diaphragm or sustained (\>10s)

Secondary Outcome Measures
NameTimeMethod
Airway view at the time of laryngoscopy as categorized by the modified Cormack-Lehane classification (before external manipulation)from start of induction to 5 minutes of successful ventilation

Data is reported categorically as follows 1(Full view of glottis),2a(Partial view of glottis), 2b(Only posterior extremity of glottis seen or only arytenoid cartilages), 3(Only epiglottis seen, none of glottis seen) and 4(Neither glottis nor epiglottis seen)

Diastolic Blood Pressurefrom the start of induction drug administration to about 5 minutes after successful ventilation
Systolic Blood Pressurefrom the start of induction drug administration to about 5 minutes after successful ventilation
End-tidal carbon dioxide (CO2)from the start of induction drug administration to about 5 minutes after successful ventilation
Number of participants who had nausea as assessed by the score on the Post Anesthesia Care Unit Survey of Modified Time Principle Inductionwithin 24 hours after surgery
Number of times tracheal intubations are attempted5 minutes after intubation and successful ventilation
Number of participants for whom tracheal intubations failedAfter 3 failed intubation attempts (less than 7 minutes from start of intubation)
Number of participants for whom tracheal intubations were successful on the first attempt5 minutes after intubation and successful ventilation
Satisfaction of providers with intubating conditionsfrom 5 minutes of successful ventilation

Providers will answer yes or no for satisfaction

Oxygen saturation (SpO2)from the start of induction drug administration to about 5 minutes after successful ventilation
Heart Ratefrom the start of induction drug administration to about 5 minutes after successful ventilation
Number of participants that had injury associated with intubationwithin 24 hours after surgery

Injury is defined as injury to dentition, lips, tongue, and pharyngeal bleeding.

Number of participants who had vomiting as assessed by the score on the Post Anesthesia Care Unit Survey of Modified Time Principle Inductionwithin 24 hours after surgery
Overall patient satisfaction as assessed by the score on the Post Anesthesia Care Unit Survey of Modified Time Principle Inductionwithin 24 hours after surgery

This is scored from 0(not satisfied) to 10(extremely satisfied)

Number of participants with muscle paralysis awareness prior to loss of consciousness as assessed by the Post Anesthesia Care Unit Survey of Modified Time Principle Inductionwithin 24 hours after surgery
Number of participants who had presence of sore throat as assessed by the score on the Post Anesthesia Care Unit Survey of Modified Time Principle Inductionwithin 24 hours after surgery

This is scored from 0(no pain) to 10(worst pain)

Number of participants who had recollection of pain on inductionwithin 24 hours after surgery
