Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

825
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 Procedures I: Esophagogastroduodenoscopy

1.5K
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:

General Anesthesia: Overview

852
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Endoscopic Procedures V: ERCP

4.2K
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 II: Colonoscopy

857
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Skeletal Muscle Relaxants: Therapeutic Uses01:31

Skeletal Muscle Relaxants: Therapeutic Uses

1.1K
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx...

Area of Science:

  • Anesthesiology
  • Gastroenterology
  • Patient Safety

Background:

  • Anesthetic care in endoscopy requires careful consideration of safety and monitoring.
  • Propofol is commonly used for sedation during endoscopic procedures.

Purpose of the Study:

  • To review practical aspects of anesthetic care in the endoscopy suite.
  • To address general approach, safety, and monitoring issues.

Main Methods:

  • Review of current literature on anesthetic practices in endoscopy.
  • Analysis of safety concerns and monitoring techniques.

Main Results:

  • Recent studies raise concerns about the safety of higher propofol doses for sedation.
  • Careful propofol titration, use of synergistic agents (ketamine, dexmedetomidine), and anesthetic depth monitoring can limit propofol dosage.
  • Capnography may detect airway compromise earlier than pulse oximetry, enhancing patient safety.

Conclusions:

  • Sedation/anesthesia in endoscopy carries inherent risks.
  • Clinical judgment and experience are crucial for complex procedures and high-risk patients.
  • Establishing dedicated anesthesiologist sedation services may improve care.
