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 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...

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...

Tracheostomy Care II: Procedure

Tracheostomy Care II: Procedure

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 and...

Tracheostomy Suctioning II: Procedure

Tracheostomy Suctioning II: Procedure

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...

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,...

Summary

Total laryngectomy does not affect Eustachian tube function. This study found no significant differences in Eustachian tube function between patients who underwent total laryngectomy and healthy controls.

Area of Science:

Otolaryngology
Head and Neck Surgery
Physiology

Background:

Eustachian tube function is crucial for middle ear health.
Total laryngectomy alters upper airway anatomy and airflow.
The impact of total laryngectomy on Eustachian tube function remains unclear.

Purpose of the Study:

To investigate short-term and long-term changes in Eustachian tube function after total laryngectomy.
To compare Eustachian tube function in total laryngectomee patients with healthy controls.

Main Methods:

53 total laryngectomy patients (grouped by time post-surgery) and 51 healthy volunteers were assessed.
Eustachian tube function was evaluated using tympanometry (P1, P2, P3) with Toynbee and Valsalva maneuvers.
Functionality criteria included P1-P2 >10 daPa or Pmax - Pmin >15 daPa.

Main Results:

No statistically significant differences were found in Pmax - Pmin, P2, or P1-P2 values among the groups.
No significant differences were observed in Pmax - Pmin values between the right and left sides across groups.

Conclusions:

Total laryngectomy does not significantly alter Eustachian tube function in the short or long term.
The absence of active airflow in the upper respiratory tract post-laryngectomy does not impact Eustachian tube function.
