An Endotracheal Intubation

  • It requires skill and frequent practice.
  • It carries the risk of esophageal intubation.
  • It may delay other critical interventions if not performed efficiently.
100

The "Why"? 

What are the indications of Endotracheal intubation?

Airway Protection: Patients unable to protect their own airway due to conditions like apnea or a low GCS score (typically ≤8) require intubation. 

Oxygenation and Ventilation: Intubation is indicated when a patient experiences hypoxia (poor oxygenation) or hypercarbia (poor ventilation, often with respiratory acidosis) that cannot be corrected with basic airway management. 

Failure to Maintain Airway Patency: This includes patients with airway obstructions that basic methods cannot manage, or those with a high risk of airway collapse. 

Anticipated Clinical Deterioration: Intubation may be performed to secure the airway when a patient's condition is expected to worsen rapidly and lead to respiratory failure.

Mention the immediate complication of endotracheal intubation during or right after intubation 

(BATHES )

Bradycardia/ Hypotension

Aspiration

Trauma ( Airway trauma, bleeding, dental trauma )

Hypoxia

Esophageal Intubation 

Selectively intubated ( usually the right Mainstem  )

This structure prevents food or liquids from entering the airway during the swallowing process.

Epiglottis 

200

During trauma intubation, this maneuver is used to open the airway while protecting the cervical spine.

Jaw Thrust

200

A device placed above the glottis to secure the airway without vocal cord visualization.

supraglottic airway (LMA, i-gel, King LT)

These are devices inserted blindly and provide a secure airway without visualization of the vocal cords.

 They’re fast, effective, and ideal for experienced and less confident providers during high-stress situations

Advantages: Quick placement, Less training required than intubation, and excellent for cardiac arrest

200

The "How"? 

What are the Methods used to perform the intubation?

Direct Laryngoscopy: directly visualize the vocal cords using the laryngoscope 
Video Laryngoscopy: a video screen to provide a view of the airway, which improves visualization. Nasotracheal Intubation: Placing the tube through the nose instead of the mouth. 
Awake Intubation: Performing intubation with the patient awake, often using a fiber optic bronchoscope to guide the tube. 


200

Mention early complication of endotracheal intubation

Hypotension/shock

Pneumothorax /Barotrauma

Incorrect tube depth  or displacement 

Vocal cord injury / laryngeal edema

vs

Measurement

300

What tool is used to visualize the vocal cords during intubation?

Larngoscope 

300

How would you predict difficulty intubation? 

L: look Externally: Signs of trauma, large tongue, or obesity.

E: evaluate 3-3-2 Rule: A measure of the length of the airway opening.

M: mallampati Score: Visual assessment of the tongue and throat.

O: obstruction: Blockage or swelling in the upper airway.

N: neck Mobility: Limited movement, such as with cervical spine immobilization.

Mention the Late complications of endotracheal intubation

Tracheo stenosis

Ventilator-Associated Pneumonia ( VAP)

Necrosis/ulceration of the tracheo-mucosa 

Laryngeal granuloma/ scarring

One of the three cartilages of the larynx, alongside the thyroid and cricoid

Arytenoid cartilage

You’re suctioning a patient who has vomited during resuscitation. What’s the maximum time you should apply suction to prevent hypoxia?

No more than 10–15 seconds

400

Methods to clinically confirm endotracheal tube placement immediately after intubation

Chest rises during baging 

Mist on the tube 

Five-point auscultation

Field intubation is the placement of an advanced airway or endotracheal tube (ET) by emergency medical services (EMS) personnel outside the hospital setting.what are the strategies during intubation process 

Preparation

This is the airway opening seen during laryngoscopy

The Glottis 

500

Airway clearance is mainly used to remove secretions, foreign bodies, or liquids that obstruct the airway to ensure airway patency and effective ventilation. Mention commonly used tools 

  • Suction Machine: Uses negative pressure to remove mucus, blood, and vomit from the mouth, pharynx, or airway.
  • Suction Catheter: Used with the suction machine, inserted deep into the airway for targeted suctioning.
  • Yankauer Suction Tip: Commonly used to clear secretions from the mouth and pharynx; its rigid design is suitable for removing larger amounts of secretions.
  • Endotracheal Suction Catheter: Used to suction secretions inside the trachea to prevent blockage and infection.
500

The most reliable method for confirming ET tube placement and monitoring ventilation continuously, which is more available in hospital settings 

Waveform capnography 

  • Confirming tube placement
  • Monitoring ventilation quality during CPR
  • Detecting ROSC (Return of Spontaneous Circulation)
  • Assessing for airway obstruction or bronchospasm

Normal end-tidal CO₂ readings range from 35–45 mmHg, and a continuous waveform provides a clear picture of ventilation status in real-time.

After successful intubation, the patient’s SpO₂ drops suddenly, and breath sounds are heard only on the right side. What complication has likely occurred?

It’s 07:15 AM. You and your partner respond to a two-vehicle collision on a rural highway. A 32-year-old male driver was found unconscious in the front seat after striking a tree. The dashboard and steering wheel show significant damage. There’s heavy bleeding from the scalp, and the patient is breathing irregularly.

On initial Assessment:

  • General Impression: Unconscious, shallow respirations, gurgling sounds.

  • Airway: Partially obstructed with blood and secretions.

  • Breathing: Rate 8/min, irregular, shallow chest rise.

  • Circulation: Carotid pulse weak, radial pulse absent.

  • Skin: Cool, pale, diaphoretic.

  • SpO₂: 78% on room air.

  • GCS: 5 (E1, V1, M3).Qn Outline the management of this patient
