Study Notes

Airway Management Overview

Determine necessity of intubation based on patient’s airway and breathing compromise.
Many cases of compromised airway (e.g., snoring, gurgling) can be managed with conservative methods (positioning, nasopharyngeal airway).

Indications for Intubation

High-grade airway obstruction of any cause.
Suspected imminent airway obstruction.
Inability to maintain or protect the airway long-term.
Severe hypoxia unresponsive to less invasive treatments.
Severe hypercarbia unresponsive to less invasive treatments.

Identifying Difficult Airways

Recognize signs of potentially difficult intubation and plan accordingly.
“LEMON” mnemonic aids in assessing airway difficulty:
- Look: Inspect face and neck for dysmorphism, obesity, dental issues, trauma, or swelling.
- Evaluate 3/3/2:
  - 3 finger breadths between incisors (mouth open).
  - 3 finger breadths from mental vertex to hyoid bone.
  - 2 finger breadths from hyoid bone to thyroid notch.
- Mallampati Score: Visualize posterior pharynx; limited utility in critically ill patients.
- Obstruction: Check for foreign bodies, listen for stridor.
- Neck Mobility: Assess range of motion; consider trauma patients with cervical spine immobilization.

Preparation for Difficult Intubation

Prepare for failed standard intubation; have backup equipment ready (e.g., surgical cricothyrotomy).
Ensure backup equipment is accessible before administering sedatives or paralytics.
Call for assistance, especially from difficult airway management teams if patient condition allows.

Breathing Management

Apnea and Agonal Respirations: Prioritize ensuring patient is breathing and provide assisted ventilation via BVM.
BVM ventilation only for patients with agonal or absent respirations; avoid in spontaneously breathing patients to prevent worsening hypoxia.

Troubleshooting BVM Ventilation

Patient Position: Ensure patient is flat with no obstructions; use "sniffing position" for optimal airflow.
Your Position: Stand squarely at the head of the bed for effective BVM.
Mask Technique: Utilize the “C/E” technique for mask placement.
Two-person Technique: Partner holds mask while others squeeze the bag for better ventilation, especially in large patients.
Oropharyngeal Airway: Use to maintain airway patency during BVM; essential for effective ventilation.

Key Takeaway

Successful oxygenation is critical; patients typically die from lack of oxygenation rather than failure to intubate.

Description

This quiz evaluates your understanding of airway management and the criteria for intubation. It covers various scenarios where patients may require different interventions for compromised airways and emphasizes the importance of conservative management strategies. Test your knowledge on how to effectively assess and handle airway emergencies.
