Summary
The Airway Scope provides high success rates for tracheal intubation in lateral positions, comparable to supine. Intubation times were not significantly increased, making it a useful tool for lateral patient positioning.
Area of Science:
- Anesthesiology
- Airway Management
Background:
- Tracheal intubation in the lateral position is challenging due to compromised laryngeal views during direct laryngoscopy.
- The Airway Scope aids intubation even with poor laryngeal visualization.
Purpose of the Study:
- To compare the efficacy of the Airway Scope for tracheal intubation in supine versus left- and right-lateral positions.
- To test if lateral position intubation time exceeds supine by more than 10 seconds.
Main Methods:
- Adult patients were randomized into supine, left-lateral, or right-lateral positions (n=43 each).
- Laryngeal views were assessed with a Macintosh laryngoscope before intubation with the Airway Scope.
Main Results:
- Intubation success rates were high: 100% in lateral positions and 98% in supine.
- Intubation times were similar across all positions (supine: 22±7s, left-lateral: 24±5s, right-lateral: 24±6s).
- Airway complication incidences were similar, with no reported hypoxia, dental injury, or esophageal intubation.
Conclusions:
- The Airway Scope demonstrates high success rates for tracheal intubation in lateral positions, despite poorer laryngoscopic views.
- Intubation time with the Airway Scope in lateral positions did not significantly exceed that in the supine position.
- The Airway Scope is a valuable device for tracheal intubation in laterally positioned patients.

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...
01:15Endotracheal 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...

Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.

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...

01:17Endotracheal 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.

Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...
