General Anesthesia: Overview01:24

General Anesthesia: Overview

518
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...

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...

Parenteral Anesthetics: Overview01:24

Parenteral Anesthetics: Overview

519
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.

Local Anesthetics: Pharmacokinetics01:13

Local Anesthetics: Pharmacokinetics

1.1K
The potency and duration of action of local anesthetics (LAs) are determined by their pharmacokinetics. Pharmacokinetics describes how LAs are absorbed, distributed, metabolized, and eliminated from the body. When administered to the vascular tissues, LAs are quickly absorbed and enter the systemic circulation, reducing their localized effects. Adding vasoconstrictors such as epinephrine to LAs reduces their absorption into the systemic circulation, making them clinically effective. The...

Local Anesthetics: Common Agents and Their Applications01:23

Local Anesthetics: Common Agents and Their Applications

829
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

Inhalational Anesthetics: Overview01:20

Inhalational Anesthetics: Overview

896
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

Area of Science:

  • Medical Education
  • Anesthesiology
  • Health Informatics

Background:

  • Patient decision aids are educational tools designed to aid patients and clinicians in making informed healthcare choices.
  • The shift towards patient-centered care necessitates tools that facilitate shared decision-making between patients and providers.
  • Anesthesiology can benefit from these tools to enhance patient engagement and understanding.

Purpose of the Study:

  • To review the role and impact of patient decision aids in healthcare, particularly within anesthesiology.
  • To highlight the benefits of patient decision aids in promoting shared decision-making and patient-centered care.
  • To discuss the current state and future directions for patient decision aids in anesthesia.

Main Methods:

  • Review of recent research on the efficacy and application of patient decision aids.
  • Analysis of studies demonstrating patient outcomes associated with decision aid use.
  • Examination of established frameworks for developing decision aids in anesthesia.

Main Results:

  • Patient decision aids are associated with improved patient knowledge, reduced anxiety, depression, and decisional conflict.
  • These tools effectively support shared decision-making in clinical settings, including anesthesiology.
  • A structured approach for developing anesthesia-specific decision aids has been developed.

Conclusions:

  • Patient decision aids are valuable for advancing patient-centered care and shared decision-making in anesthesia.
  • Ongoing research focuses on implementing decision aids in monitored anesthesia care discussions.
