Stages of General Anesthesia01:22

Stages of General Anesthesia

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

General Anesthesia: Overview

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...
Parenteral Anesthetics: Overview01:24

Parenteral Anesthetics: Overview

Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

Cardiomyopathy VII: Pre and Post Operative Nursing Management

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 Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

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...
Local Anesthetics: Adverse Effects01:12

Local Anesthetics: Adverse Effects

While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

Area of Science:

  • Anesthesiology
  • Geriatrics
  • Neuroscience

Background:

  • Postoperative Cognitive Dysfunction (POCD) is a decline in cognitive function post-surgery, primarily affecting elderly individuals.
  • The multifactorial nature of POCD is recognized, but the specific roles of surgery versus general anesthesia remain debated.
  • Understanding POCD's etiology is crucial for developing effective interventions.

Purpose of the Study:

  • To review current clinical and preclinical evidence regarding the occurrence of POCD.
  • To summarize recent research on the factors contributing to POCD.
  • To explore potential pharmacologic strategies for POCD prevention and treatment.

Main Methods:

  • Comprehensive literature search of clinical and preclinical studies on POCD.
  • Synopsis of existing data on cognitive changes after surgical procedures.
  • Analysis of research on anesthetic effects and surgical impact on cognition.

Main Results:

  • POCD is a significant concern in the elderly following surgical interventions.
  • Evidence suggests a complex interplay of surgical and anesthetic factors in POCD development.
  • Recent research highlights various potential pathways and targets for intervention.

Conclusions:

  • Further research is needed to elucidate the precise mechanisms underlying POCD.
  • Pharmacologic approaches show promise for preventing and treating POCD.
  • Multidisciplinary strategies may be required to mitigate POCD in vulnerable populations.
