Oxygen Delivering System III: Tracheostomy and T-piece01:23

Oxygen Delivering System III: Tracheostomy and T-piece

9.5K
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...

Cardiopulmonary Resuscitation II: ACLS Airway Management

1.2K
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...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

958
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...

Tracheostomy Care II: Procedure01:25

Tracheostomy Care II: Procedure

2.9K
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.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

3.7K
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

The Hyoid Bone01:12

The Hyoid Bone

6.8K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

Area of Science:

  • Otolaryngology
  • Medical Devices
  • Surgical Techniques

Background:

  • Laryngeal paralysis, affecting vocal cord function, requires effective management strategies.
  • Unilateral paralysis necessitates arytenoid adduction, while bilateral paralysis requires arytenoid abduction.

Purpose of the Study:

  • To develop a novel device and technique for minimal-access management of laryngeal paralysis.
  • To achieve precise arytenoid adduction and abduction for vocal cord repositioning.

Main Methods:

  • A human cadaver study combined with engineering design was employed.
  • Instrumentation was developed to secure the arytenoid muscular process in desired positions.
  • 3D computed tomographic (CT) imaging and video documentation evaluated the surgical technique's feasibility.

Main Results:

  • An optimal implant was identified as a 0.36-mm wire with a distal spring-wound coil.
  • The device was successfully placed via a small drill hole in the thyroid cartilage.
  • Endoscopic visualization and 3D CT confirmed the feasibility of positioning the vocal cords via adduction or abduction.

Conclusions:

  • The feasibility of a minimal-access technique for arytenoid adduction and abduction has been confirmed.
  • A new device and surgical method offer a potential solution for managing laryngeal paralysis.
