Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

77
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...

Suctioning the Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

375
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Cardiopulmonary Resuscitation II: ACLS Airway Management

88
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...

Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

924
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.

Endotracheal Tube Extubation01:24

Endotracheal Tube Extubation

1.4K
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

3.0K
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...

This case highlights the importance of considering radiolucent airway foreign bodies (FBs) in patients with chronic respiratory symptoms. Both rigid and flexible bronchoscopy are effective for FB removal, with flexible techniques aiding peripheral lesion access.

Area of Science:

  • Pulmonology
  • Medical Imaging
  • Interventional Bronchoscopy

Background:

  • Chronic cough, shortness of breath, and fever can mimic asthma exacerbations.
  • Radiolucent airway foreign bodies (FBs) may present with non-specific respiratory symptoms.
  • Computed tomography (CT) is crucial for diagnosing endobronchial FBs.

Purpose of the Study:

  • To illustrate the diagnostic and management principles for airway foreign bodies.
  • To emphasize the differential diagnosis of radiolucent airway FBs in chronic respiratory conditions.
  • To highlight the complementary roles of rigid and flexible bronchoscopy in FB removal.

Main Methods:

  • A contrasted computed tomography (CT) scan identified two endobronchial linear foreign bodies (FBs).
  • Rigid bronchoscopy under general anesthesia was used for the proximal FB removal.

  • Flexible bronchoscopy via endotracheal tube was employed for the distal FB removal in the same session.

    • Main Results:

    • Two endobronchial linear foreign bodies (FBs) were successfully diagnosed via CT scan.
    • Complete removal of both FBs was achieved using a combination of rigid and flexible bronchoscopy.
    • The case demonstrates successful management of a challenging airway FB scenario.

    Conclusions:

    • Airway foreign body (FB) diagnosis requires consideration of radiolucent FBs in patients with chronic respiratory symptoms.
    • Rigid and flexible bronchoscopy are complementary tools for airway FB removal.
    • Ensuring complete FB removal should be a standard practice in airway management.
