Topical Oral Anesthesia Adjuncts in Conventional Intubation on First-Pass Success Rate

Topical Oral Anesthesia Adjuncts in Conventional Intubation: A Randomized Controlled Trial Evaluating the Impact of Topical Oral Anesthesia on First-pass Success Rate

This study aims to determine the first-pass success rate in video laryngoscopy and other parameters that topical anesthesia can affect during intubation.

In Thailand, conventional intubation or sedation without paralysis is still the most common method of intubation due to the lack of emergency physicians at primary care centers. A pilot study had shown that topical oral anesthesia can improve the first-pass success rate in conventional intubation by direct laryngoscopy. This study aims to determine the first-pass success rate in video laryngoscopy and other parameters that topical anesthesia can affect during intubation.

Inclusion Criteria:

• Patients in emergency department that have indication for conventional intubation
• Age > 18 yr

Exclusion Criteria:

• Patient who undergo RSI
• Patient who falls in cardiac arrest airway algorithm
• Patient who is currently pregnancy
