Oxygen Delivering System III: Tracheostomy and T-piece

Oxygen Delivering System III: Tracheostomy and T-piece

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...

Endotracheal Intubation I: Procedure

Endotracheal Intubation I: Procedure

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...

Tracheostomy: Procedure and Tubes

Tracheostomy: Procedure and Tubes

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...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

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,...

Tracheostomy Decannulation

Tracheostomy Decannulation

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...

Summary

Most patients (90%) with a voice prosthesis after total laryngectomy and tracheoesophageal puncture need size changes. Women were more likely to maintain stable prosthesis size over time.

Area of Science:

Otolaryngology
Speech-Language Pathology
Prosthetics

Background:

Total laryngectomy and tracheoesophageal puncture (TEP) are procedures for voice restoration.
Voice prostheses are crucial for TEP voice restoration.
Prosthesis size stability is important for optimal function and patient comfort.

Purpose of the Study:

To investigate the long-term size stability of voice prostheses.
To identify factors influencing the need for prosthesis size changes after TEP.

Main Methods:

Retrospective chart review of patients with total laryngectomy and TEP.
Inclusion criteria: minimum of 3 years of follow-up data post-prosthesis placement.
Demographic data and prosthesis size changes were analyzed.

Main Results:

90% of patients (45/50) required at least one prosthesis size change.
Prosthesis size was stable in only 10% of patients.
Female sex was statistically associated with a higher likelihood of stable prosthesis size (Fisher exact test = 0.035).

Conclusions:

A significant majority of patients require prosthesis size adjustments beyond the initial healing period.
Continuous reassessment of the fistula tract is necessary during prosthesis changes to ensure proper fit.
Understanding factors influencing size stability can guide clinical management.
