Summary
Retrograde intubation, a key part of the Difficult Airway Algorithm, can lead to the Macklin effect. This rare complication involves air dissecting into the mediastinum following alveolar rupture during the procedure.
Area of Science:
- Anesthesiology
- Pulmonology
- Critical Care Medicine
Background:
- Retrograde intubation is a standard procedure within the American Society of Anesthesiologists' Difficult Airway Algorithm.
- Competency in retrograde intubation is expected for all anesthesiologists.
- Awareness of potential complications associated with retrograde intubation is crucial.
Observation:
- A case report details a patient who developed signs and symptoms consistent with the Macklin effect after retrograde intubation.
- The Macklin effect is a specific pathophysiological process involving pulmonary complications.
Findings:
- The Macklin effect is characterized by a three-step process: blunt traumatic alveolar rupture, air dissection along bronchovascular sheaths, and subsequent mediastinal spread of pulmonary interstitial emphysema.
- This case highlights a potential iatrogenic complication of an established difficult airway management technique.
Implications:
- Anesthesiologists must be vigilant for the Macklin effect during and after retrograde intubation.
- Understanding the pathophysiology of the Macklin effect is essential for prompt diagnosis and management.
- This case underscores the importance of recognizing and managing rare complications in airway management.

01:15Endotracheal Intubation I: Procedure
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...

01:17Endotracheal Intubation II: Nursing Management
Endotracheal intubation is a critical procedure that can be lifesaving for many patients with respiratory distress or failure. The role of nursing in managing endotracheal tubes is pivotal, as it involves pre-intubation preparation, assisting during the procedure, and post-extubation care.
1. Nursing Care of Patients Before Intubation
Before the endotracheal intubation procedure, nurses play an essential role in ensuring the process goes smoothly. The nurses must be familiar with intubation...

01:24Endotracheal Tube Extubation
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.

01:30Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
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 interventions are...
01:21Tracheostomy Decannulation
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...
