General Anesthesia: Overview

209
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 IV: Sigmoidoscopy and Laproscopy

71
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...

Summary
This summary is machine-generated.

Perioperative cognitive dysfunction (PCD) is underrecognized by Spanish anesthesiologists. Improved awareness, risk factor detection, and established protocols are crucial for better patient care and outcomes.

Area of Science:

  • Anesthesiology
  • Neuroscience
  • Geriatric Medicine

Background:

  • Perioperative cognitive dysfunction (PCD) is a growing concern due to an aging surgical population.
  • Understanding current clinical practices is essential for addressing PCD prevalence.

Purpose of the Study:

  • To evaluate the clinical practices of Spanish anesthesiologists concerning perioperative cognitive dysfunction.
  • To identify gaps in the assessment and management of PCD.

Main Methods:

  • A prospective online survey was conducted among Spanish anesthesiologists.
  • The survey was distributed by the Neurosciences Section and SEDAR, yielding 544 responses.

Main Results:

  • A significant majority (54.4%) never perform preoperative cognitive impairment assessments; only 7.5% always do.
  • Most respondents (79.6%) lack intraoperative protocols for patients at risk of PCD.
  • Regional anesthesia is preferred over general anesthesia for PCD prevention, and benzodiazepines are considered high-risk.

Conclusions:

  • Perioperative cognitive dysfunction is underdiagnosed and underappreciated among surveyed Spanish anesthesiologists.
  • There is a need for increased awareness, improved risk factor detection, and standardized postoperative assessment for PCD.
  • Development of guidelines, protocols, and continuing education is recommended, with anesthesiologists as key members of multidisciplinary teams.
