Tracheostomy Decannulation01:21

Tracheostomy Decannulation

1.6K
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

Tracheostomy Care II: Procedure

1.6K
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...

The relative amounts of reactants and products represented in a balanced chemical equation are often referred to as stoichiometric amounts. However, in reality, the reactants are not always present in the stoichiometric amounts indicated by the balanced equation.

Short-distance Transport of Resources

17.8K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

3.5K
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...

Tracheostomy Suctioning II: Procedure01:23

Tracheostomy Suctioning II: Procedure

1.9K
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:

  • Critical Care Medicine
  • Surgical Procedures
  • Airway Management

Background:

  • Percutaneous dilatational tracheostomy (PDT) is an efficient intensive care procedure.
  • Standard PDT often requires bronchoscopic or ultrasound guidance, limiting its use in resource-constrained environments.

Purpose of the Study:

  • To evaluate the feasibility, safety, and learning curve of landmark-guided PDT.
  • To assess this technique as an alternative when visualization tools are unavailable.

Main Methods:

  • Retrospective analysis of 71 adult patients undergoing landmark-guided PDT without visualization.
  • Procedures performed by a newly trained head and neck surgeon.
  • Outcomes included procedure duration, complication rates, and predictors of difficulty.

Main Results:

  • Median procedure time was 7.0 minutes, with a significant learning curve observed (p < 0.001).
  • Complication rate was 14.1%, with limited major events (1 bleed, 2 pneumothoraces).
  • Prior cerebrovascular accident and increased cricoid-manubrium distance predicted longer procedure times.

Conclusions:

  • Landmark-guided PDT without visualization is feasible and safe after a brief learning phase.
  • This technique is a practical option in settings lacking advanced imaging.
  • Careful patient selection and operator training are essential for successful implementation.
