Abstract

Insights

The volatile anesthetic desflurane impairs platelet aggregation, similar to halothane, but does not affect alpha-degranulation. This suggests desflurane may impact platelet thromboxane receptor signaling.

Area of Science:

  • Anesthesiology
  • Hematology
  • Pharmacology

Background:

  • Volatile anesthetics like desflurane and halothane are commonly used in surgery.
  • Platelet activation is crucial for hemostasis and thrombosis.
  • Understanding anesthetic effects on platelets is vital for patient safety.

Purpose of the Study:

  • To investigate the in vitro effects of desflurane on platelet activation.
  • To compare desflurane's effects with those of halothane.
  • To elucidate the specific mechanisms of desflurane-induced platelet dysfunction.

Main Methods:

  • Platelet-rich plasma was exposed to desflurane, halothane, or air (control).
  • Platelets were stimulated with agonists like ADP and collagen.
  • Platelet aggregation and CD62P expression (a marker of activation) were measured using Born aggregometry and flow cytometry.

Main Results:

  • Both desflurane and halothane significantly reduced platelet aggregation.
  • The inhibitory effect on aggregation was more pronounced with desflurane.
  • No significant difference in CD62P expression was observed between anesthetic-exposed and control platelets.

Conclusions:

  • Desflurane differentially affects platelet activation, impairing aggregation but not alpha-degranulation.
  • These findings suggest a mechanism involving impaired thromboxane receptor signaling, similar to halothane.
  • Desflurane's impact on platelet function warrants consideration in clinical settings.

Inhalational Anesthetics: Overview01:20

Inhalational Anesthetics: Overview

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...

Depolarizing Blockers: Pharmocokinetics

Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...
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.
Depolarizing Blockers: Mechanism of Action01:28

Depolarizing Blockers: Mechanism of Action

Depolarizing blockers act on skeletal muscle fibers' membranes and induce their depolarization. Most depolarizing blockers have two quaternary N+ atoms that bind the nicotinic acetylcholine receptors and cause neuromuscular blockade within minutes.
Succinylcholine is the most commonly used depolarizing blocker. Chemically, it constitutes two molecules of acetylcholine joined together by an acetate methyl group. They act on the receptors in the same way as acetylcholine. Because succinylcholine...

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...

Nondepolarizing (Competitive) Neuromuscular Blockers: Pharmacological Actions

Nondepolarizing neuromuscular blockers prevent the membrane depolarization of muscle cells and inhibit muscle contraction. These are usually administered with anesthetics to achieve complete muscle relaxation. Upon administration, these drugs first block the small, rapidly contracting muscles of the face and hands, followed by the larger muscles of the trunk and the intercostal muscles. The diaphragm is the last muscle to be affected.
Although all competitive neuromuscular blockers are designed...
