Summary
Sellick maneuver, applying cricoid cartilage pressure during anesthesia induction, is widely used but its efficacy in preventing gastric regurgitation is debated. Proper technique and force are crucial, as improper use can lead to complications.
Area of Science:
- Anesthesiology
- Airway Management
Background:
- The Sellick maneuver, or cricoid cartilage pressure, is a standard technique during rapid sequence anesthesia induction.
- It aims to prevent aspiration of gastric contents by occluding the esophagus.
Purpose of the Study:
- To review the indications, technique, and complications associated with the Sellick maneuver.
- To discuss the reasons for questioning its efficacy and potential abandonment by some practitioners.
Main Methods:
- Review of existing literature on cricoid cartilage pressure.
- Discussion of anatomical considerations and clinical evidence.
Main Results:
- The maneuver's effectiveness is debated, with studies raising doubts about its protective capabilities.
- Improper application can lead to complications such as vocal cord closure and ventilation difficulties.
Conclusions:
- While widely accepted, the Sellick maneuver is not foolproof in preventing pulmonary aspiration.
- Correct anatomical knowledge and precise force application are essential for its safe and potentially effective use.

01:21Larynx
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

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...
01:22Trachea
The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of the...

01:28Tracheostomy: Procedure and Tubes
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

01:22Cardiopulmonary Resuscitation II: ACLS Airway Management
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. 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...
01:23Oxygen Delivering System III: Tracheostomy and T-piece
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...
