Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques01:30

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

92
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...

Endotracheal Tube Extubation01:24

Endotracheal Tube Extubation

1.5K
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....

Endotracheal Intubation I: Procedure

3.2K
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...

Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

1.0K
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.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

278
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Tracheostomy Suctioning II: Procedure01:23

Tracheostomy Suctioning II: Procedure

603
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...

Area of Science:

  • Medical Devices
  • Pediatric Critical Care
  • Anesthesiology

Background:

  • Neonatal intubation is challenging, with low first-pass success and high complication rates.
  • Video laryngoscopes offer improved views and success rates, particularly for less experienced clinicians.
  • Variations in video laryngoscope design may impact their usability.

Purpose of the Study:

  • To assess and compare the usability of six different neonatal video laryngoscope devices.
  • To evaluate clinician satisfaction, device efficacy, and efficiency during simulated neonatal intubation.

Main Methods:

  • Mixed-methods approach including simulations, observations, interviews, and questionnaires.
  • Assessed six devices: C-MAC, GlideScope Core (Miller and hyperangle blades), Koala Vision Ultra, Koala Handheld, and Parker Neonatal.
  • Usability measured by clinician satisfaction (SUS, NASA-TLX, preference), efficacy (first-pass success, attempts), and efficiency (time, function tests).

Main Results:

  • Significant variability in design and usability was observed among the neonatal video laryngoscopes.
  • All devices were suitable for neonatal intubation.
  • Koala Handheld, C-MAC, and GlideScope Core Miller showed the highest usability scores.

Conclusions:

  • Neonatal video laryngoscope usability differs substantially, influenced by device design.
  • Further research is needed to confirm these usability findings in clinical settings.
