Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

1.2K
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...

Cardiomyopathy VII: Pre and Post Operative Nursing Management

460
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Pre-Procedural Guidelines for Assessing Blood Pressure

880
Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the...

Endoscopic Procedures I: Esophagogastroduodenoscopy

2.4K
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:

Area of Science:

  • Anesthesiology
  • Surgical Patient Care
  • Clinical Practice Guidelines

Background:

  • Preoperative fasting is crucial for patient safety during general anesthesia.
  • Prolonged fasting can lead to dehydration, hypoglycemia, electrolyte imbalance, and patient discomfort.

Purpose of the Study:

  • To assess adherence to current preoperative fasting guidelines in a large surgical unit.
  • To identify factors contributing to prolonged fasting and areas for improvement.

Main Methods:

  • A survey of 292 adult patients undergoing elective and emergency surgeries at the Royal Infirmary of Edinburgh.
  • Data collected on preoperative fasting duration and staff-administered advice using a standardized questionnaire.

Main Results:

  • Median fasting from solids was 13.5 hours for elective and 17.38 hours for emergency patients.
  • Median fasting from fluids was 9.36 hours for elective and 12.97 hours for emergency patients.
  • Elective patients fasted longer than recommended, indicating slow clinical practice change.

Conclusions:

  • Current clinical practice often results in preoperative fasting periods exceeding guidelines.
  • Universal fasting instructions and patient choice contribute to unnecessary prolonged fasting.
  • Service improvement necessitates targeted staff education, improved clinical communication, and provision of written patient information.
