Summary
This study found that an awake fiberoptic intubation (AFOI) protocol is feasible for patients with simulated difficult airways. The AFOI protocol demonstrated a high success rate, patient satisfaction, and effective amnesia with minimal complications.
Area of Science:
- Anesthesiology
- Airway Management
Background:
- Awake fiberoptic intubation (AFOI) is a critical technique for managing difficult airways.
- Assessing the feasibility of standardized AFOI protocols is essential for clinical practice.
Purpose of the Study:
- To evaluate the feasibility of a specific awake fiberoptic intubation (AFOI) protocol.
- To determine the safety and efficacy of this AFOI protocol in patients with simulated difficult airways.
Main Methods:
- A protocol involving conscious sedation, regional anesthesia, and fiberoptic intubation was applied to 40 patients.
- Key metrics recorded included procedure time, success rate, hemodynamic stability, SpO2, amnesia, patient satisfaction, and complications.
Main Results:
- The AFOI protocol was successfully completed in all patients with a 97.5% first-attempt success rate.
- Hemodynamic parameters and SpO2 remained stable, with high patient satisfaction (90%) and effective amnesia (82.5% no recall).
- Minor complications like sore throat were transient, with no other adverse events reported.
Conclusions:
- The assessed awake fiberoptic intubation protocol is feasible and safe.
- The protocol offers a high success rate, good patient tolerance, and effective amnesia, making it suitable for managing difficult airways.

Endotracheal or ET intubation is a critical medical procedure used to secure a patient's airway, often in acute respiratory distress, apnea, upper airway obstruction, ineffective clearance of secretions, high risk for aspiration, or during general anesthesia.
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...

268
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Endotracheal tube extubation is a critical procedure in weaning patients from mechanical ventilation. It involves physically removing the oral or nasal endotracheal (ET) tube, marking the final step in liberating a patient from ventilatory support.
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals....
