Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

230
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

66
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...

Appendicitis-II: Diagnostic Studies and Management

189
Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

Area of Science:

  • Medical Psychology
  • Pain Research
  • Clinical Practice

Background:

  • Preoperative expectations influence postoperative pain and outcomes.
  • Positive expectations are linked to placebo effects, while negative expectations are linked to nocebo effects.

Purpose of the Study:

  • To explore the influence of treatment expectations.
  • To understand how expectations are assessed clinically.
  • To identify methods for implementing findings in practice.

Main Methods:

  • Literature search using keywords 'expectation' and ('postoperative' or 'surgery').
  • Selection of English and German articles.
  • Examination of bibliographies for additional relevant studies.

Main Results:

  • 158 articles were identified; 49 focused on expectations and postoperative outcomes.
  • Most studies assessed expectations at baseline, hindering prospective analysis.
  • Varied measurement methods complicate cross-study comparisons.
  • Limited research exists on perioperative expectation modification or intervention development.

Conclusions:

  • Clinical trials require valid and reliable measurement tools for robust expectation investigation.
  • Further research should focus on intervention strategies to integrate treatment expectations into routine care.
