Cardiomyopathy VII: Pre and Post Operative Nursing Management01:28

Cardiomyopathy VII: Pre and Post Operative Nursing Management

243
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...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

478
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...

Cognitive Development During Adulthood

724
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Area of Science:

  • Anesthesiology
  • Geriatric Medicine
  • Neurosurgery

Background:

  • Postoperative cognitive dysfunction (POCD) is a frequent complication following surgery.
  • It significantly contributes to increased patient morbidity and mortality.
  • POCD impacts long-term health and quality of life.

Purpose of the Study:

  • To review risk factors for postoperative cognitive decline.
  • To examine the influence of surgical intervention types on cognitive function.
  • To explore anesthetic agents' neuroprotective potential and economic impact.

Main Methods:

  • A narrative literature review was conducted.
  • Searched for studies on risk factors, surgical types, anesthetic effects, quality of life, and healthcare costs.
  • Synthesized findings on postoperative cognitive alterations.

Main Results:

  • Cardiac and orthopedic surgeries show higher POCD incidence.
  • Neuroprotective effects of anesthetics remain debated but show promise.
  • POCD is a significant public health issue, affecting quality of life and increasing healthcare expenses.

Conclusions:

  • Postoperative cognitive disorders are severe and potentially fatal.
  • Vigilance in high-risk patients and procedures is essential.
  • Implementing neuroprotective strategies may be life-saving.
