Summary
First-year anesthesiology residents improve their laryngeal mask insertion (LMI) skills significantly with practice. After performing 40 LMIs, success rates increase, and the number of attempts needed decreases, demonstrating a clear learning curve.
Area of Science:
- Anesthesiology
- Medical Education
- Airway Management
Background:
- Laryngeal mask insertion (LMI) is a core skill for anesthesiologists.
- Proficiency is crucial for routine and difficult airway management.
- This study assesses resident training in LMI.
Purpose of the Study:
- To evaluate the learning curve for first-year anesthesiology residents performing LMI.
- To assess the time, success rates, and number of attempts for LMI proficiency.
- To identify common difficulties encountered during resident LMI.
Main Methods:
- Prospective, single-center study evaluating 10 anesthesiology residents.
- Tracked workdays, success rates, and attempts for LMI (LMA ProSeal™) in blocks of five.
- Documented difficulties and complications.
Main Results:
- Residents needed a mean of 18.3 days to complete 40 LMIs.
- LMI success rate within one attempt rose from 72% to 86% (p=0.09).
- Overall LMI success rate increased from 74% to 96% (p=0.001), with attempts decreasing (p=0.03).
Conclusions:
- A significant learning curve exists for LMI proficiency in anesthesiology residents.
- Dexterity and success rates improve with cumulative LMI experience.
- Common challenges include anatomical variations and airway obstructions.

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...
01:30Cardiopulmonary 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...
01:29Suctioning the Nasopharyngeal Airway
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

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.

A tracheostomy is a surgical technique that involves making an incision in the neck to provide access to the trachea. It is frequently used in medical conditions such as airway obstruction and prolonged mechanical ventilation. Effective nursing management is crucial for the long-term success of a tracheostomy.

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
