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.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

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...

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...

Endoscopic Procedures III: Video Capsule Endoscopy

Endoscopic Procedures III: Video Capsule Endoscopy

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

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...

This study introduces a new, minimally invasive endoscopic endonasal approach for conjunctivodacryocystorhinostomy (CR), offering a better solution for total lacrimal bypass when other methods fail.

Area of Science:

Ophthalmology
Surgical Innovation
Endoscopic Surgery

Background:

Lacrimal tract obstruction requires surgical reconstruction.
Established techniques like canaliculodacryocystorhinostomy and Jones tube placement have limitations.
Conjunctivo-rhinostomy (CR) is reserved for severe cases with nonfunctional lacrimal pathways.

Purpose of the Study:

To present a novel, minimally invasive technique for conjunctivo-rhinostomy (CR).
To evaluate the advantages of this new endoscopic endonasal approach for total lacrimal bypass.

Main Methods:

Description of a novel minimally invasive CR technique.
Predominantly endoscopic endonasal surgical approach.
Comparison with existing lacrimal bypass surgical options.

Keywords:

Canaliculo-dacrocystorhinostomy Conjunctivo-dacrocystorhinostomy Conjunctivorhinostomy Dacrocystorhinostomy

Main Results:

The novel technique facilitates CR through a minimally invasive endoscopic endonasal route.
This approach offers potential advantages over traditional CR methods.
Successfully addresses total lacrimal bypass in challenging cases.

Conclusions:

Minimally invasive endoscopic endonasal CR is a viable alternative for total lacrimal bypass.
This technique expands surgical options for complex lacrimal drainage issues.
Further investigation into the long-term efficacy and benefits is warranted.
