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,...

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...

Anatomy of the Ear

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Mechanical Ventilation II: Invasive Ventilation

Mechanical Ventilation II: Invasive Ventilation

Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Suctioning the Nasopharyngeal Airway

Suctioning the Nasopharyngeal Airway

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.

Surgical Outcomes

Background:

Long-term tympanostomy tubes are linked to complications like persistent perforation.
Chronic otitis media with effusion requires effective management strategies.

Purpose of the Study:

To evaluate the outcomes of subannular ventilation tube insertions.
To assess the efficacy and complications of these tubes in patients with middle-ear effusion and eustachian tube dysfunction.

Main Methods:

Retrospective case series of 57 subannular ventilation tube insertions in 45 patients.
Mean follow-up of 48 months.
Inclusion criteria: chronic otitis media with effusion, hearing loss, adhesive otitis media, tympanic membrane retraction, or perforation.

Main Results:

Mean ventilation duration of 22-23 months.
Average air-bone gap improvement of 14 dB.
Complications included blockage (16%), perforation after extrusion (9%), granulation (5%), and infection (4%).

Conclusions:

Subannular ventilation tubes are an effective option for intractable middle-ear effusion.
These tubes offer a viable solution for eustachian tube dysfunction.
The procedure demonstrates a favorable balance of efficacy and complication rates.
