Study Background
Tracheal intubation is a critical lifesaving intervention in emergency medicine, but traumatic or failed intubation attempts can lead to significant morbidity. Awake intubation—where patients remain conscious, often receiving topical anesthesia and minimal sedation—is a specialized technique used to manage predicted difficult airways or mitigate physiologic instability. While the technique is well established in anesthesiology, its practice and outcomes when performed by emergency physicians have been less characterized. This is especially pertinent in tertiary-care emergency departments (EDs) managing complex cases with high-risk airway scenarios. Understanding the incidence, success rates, and adverse event profile of emergency physician-performed awake intubations can inform clinical protocols and improve patient safety.
Study Design
This investigation is a prospective observational analysis using the Airway Interventions Registry and Observational Database, encompassing all tracheal intubations performed at a single academic tertiary-care ED over a 10-year period (January 2015 to January 2025). The cohort included adult patients undergoing first-attempt awake tracheal intubation by emergency physicians. Intubations involving sedation-only or dissociation-only strategies were excluded to isolate the outcomes of true awake approaches. The study’s primary endpoint was successful intubation without major adverse events, specifically critical hypoxemia (oxygen saturation <80%), critical hypotension (systolic blood pressure <65 mmHg), or cardiac arrest. Secondary endpoints were first-pass success rates, incidence of adverse events, and conversions to rapid sequence intubation (RSI).
Key Findings
Out of 1,213 emergency department intubations registered, 87 (7.2%) were performed awake by emergency physicians. Most patients (80%) had anatomic markers suggesting difficult airways, and 87% had physiologic predictors complicating intubation; notably, 68% had both. The primary outcome of overall success without major adverse events was achieved in 80 patients, reflecting a success rate of 92% (95% confidence interval, 86%-98%). First-pass success—crucial to minimizing airway complications—was documented in 62 cases (71%). Conversion from awake to RSI was rare, occurring in just 6.9% of cases.
Adverse event rates were low. Critical hypoxemia occurred in 3%, critical hypotension in 2%, and cardiac arrest in 2%. These rates compare favorably with previously published data on emergency intubation, where higher rates of complications are often reported, especially in critically ill populations. The findings underscore awake intubation as a safe and effective modality when appropriately selected and skillfully executed by emergency physicians.
Expert Commentary
This study adds valuable prospective evidence validating the feasibility and safety of awake intubation performed by emergency physicians in high-acuity settings. The relatively high incidence of awake attempts (7.2%) suggests growing comfort and increasing indications in the ED environment. The success rates and low adverse events signal that with adequate training and protocols, awake intubation can be integrated effectively in emergency airway management to reduce risks associated with sedation and rapid sequence approaches in physiologically vulnerable patients.
Limitations include the single-center design and potential selection bias toward academic, high-resource settings with skilled operators. Further multicenter studies could corroborate these findings in diverse clinical environments. Moreover, nuances such as choice of topical anesthetics, patient cooperation, and detailed hemodynamic monitoring were not explicitly detailed but warrant consideration in clinical application.
Conclusion
Over a decade at a tertiary academic ED, emergency physician-performed awake intubation was employed with relatively high frequency, achieving high overall and first-pass success alongside low rates of major adverse events. This evidence supports awake intubation as a valuable tool in the emergency airway repertoire, particularly for patients with difficult anatomy or physiologic instability. Future efforts should focus on broader multicenter validation, training standardization, and integration of awake intubation into airway management algorithms to enhance patient safety and outcomes.
