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 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...
Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

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:

Summary

Office-based flexible endoscopic procedures can cause significant changes in vital signs, including blood pressure and heart rate. Monitoring is recommended for older patients and those undergoing specific procedures like esophageal or laser interventions.

Area of Science:

  • Gastroenterology
  • Otolaryngology
  • Pulmonology

Background:

  • Office-based flexible endoscopic procedures are common for upper aerodigestive tract conditions.
  • Existing literature confirms the safety of these procedures.
  • However, data on hemodynamic stability during these procedures were previously lacking.

Purpose of the Study:

  • To investigate whether significant vital sign alterations occur during office-based flexible endoscopic procedures.
  • To assess hemodynamic stability in patients undergoing these interventions.

Main Methods:

  • A retrospective review of 100 consecutive patients undergoing office-based flexible endoscopic procedures was conducted.
  • Maximal changes in systolic blood pressure, diastolic blood pressure, heart rate, and oxygen saturation were recorded.
  • Baseline and maximal values were compared to identify significant alterations.

Main Results:

  • Significant mean increases were observed in systolic blood pressure (26.2 mm Hg), diastolic blood pressure (13.9 mm Hg), and heart rate (16.6 bpm).
  • Oxygen saturation showed a mean decrease of 1.6%.
  • Patients over 50, and those undergoing esophageal or laser procedures experienced significant heart rate elevations and diastolic blood pressure increases.

Conclusions:

  • Findings support previous reports of potentially significant hemodynamic changes during office-based procedures.
  • Vital sign monitoring may be advisable for patients over 50 and those undergoing esophageal or laser procedures.
  • This monitoring can help mitigate risks associated with tachycardia and hypertension.
