Suctioning the Nasopharyngeal Airway01:29

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.
Equipment Required
Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:
Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

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 to...
Endoscopic Procedures III: Video Capsule Endoscopy01:28

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, unexplained...
Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Summary

Sleep nasendoscopy effectively identifies airway collapse in sleep-disordered breathing. This diagnostic tool aids targeted treatment, with 72% of patients reporting improvement after intervention.

Area of Science:

  • Otolaryngology
  • Sleep Medicine
  • Diagnostic Imaging

Background:

  • Sleep nasendoscopy was developed in 1991 for diagnosing sleep-disordered breathing (SDB).
  • It is integral to patient selection for targeted SDB treatments.
  • This study reviews a decade of experience with this procedure.

Purpose of the Study:

  • To evaluate the effectiveness and outcomes of sleep nasendoscopy over a 10-year period.
  • To correlate sleep nasendoscopy findings with objective SDB measures.
  • To assess patient-reported outcomes following treatments guided by sleep nasendoscopy.

Main Methods:

  • Retrospective audit of 2,485 sleep nasendoscopies performed between 1995 and 2005.
  • Data extraction from patient case notes, including demographics and procedure findings.
  • Correlation analysis between sleep nasendoscopy grading, apnoea-hypopnoea index, and oxygen desaturation.

Main Results:

  • A total of 2,485 procedures were analyzed in patients with a mean age of 44.1 years and a 4:1 male predominance.
  • Sleep nasendoscopy grading showed good correlation with apnoea-hypopnoea index and mean oxygen desaturation.
  • Following treatment, 72% of patients reported feeling better, 26% reported no change, and 2% reported feeling worse.

Conclusions:

  • Sleep nasendoscopy is a valuable adjunctive tool for identifying snoring and upper airway collapse in SDB.
  • It provides quality assessment of dynamic upper airway anatomy, simulating natural sleep conditions.
  • The procedure is fundamental for guiding targeted SDB treatments and improving patient outcomes.
