Tracheostomy Care II: Procedure01:25

Tracheostomy Care II: Procedure

1.0K
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...

Suctioning the Oropharyngeal Airway

656
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...

Larynx01:21

Larynx

3.7K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Tracheostomy Suctioning II: Procedure

1.2K
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...

Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

2.3K
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...

Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

2.4K
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.

Area of Science:

  • Otolaryngology
  • Phonosurgery
  • Laryngology

Background:

  • Unilateral vocal fold palsy frequently causes hoarseness.
  • Conservative voice therapy is often limited for glottic closure insufficiency.
  • Phonosurgery, specifically injection laryngoplasty, is indicated for correction.

Purpose of the Study:

  • To evaluate the effectiveness of injection laryngoplasty for unilateral vocal fold palsy.
  • To determine optimal timing for intervention to prevent endogenous compensation.
  • To assess the duration of effect for various injectable materials.

Main Methods:

  • Review of patients undergoing injection laryngoplasty for unilateral vocal fold palsy.
  • Assessment of glottic closure insufficiency via stroboscopy (≤2 mm).
  • Analysis of outcomes with hyaluronic acid, calcium hydroxylapatite, and autologous fat injections.

Main Results:

  • Injection laryngoplasty effectively corrects glottic closure insufficiency.
  • Early intervention (within 6 months) is desired to avoid insufficient compensation.
  • Durable effects exceeding 12 months reported for specific fillers.
  • Rare complications like allergic swelling necessitate monitoring.

Conclusions:

  • Injection laryngoplasty is an effective treatment for hoarseness due to unilateral vocal fold palsy.
  • Timely intervention and appropriate patient selection optimize outcomes.
  • Injectable materials offer sustained voice improvement with minimal downtime.
