What's new in intravenous anaesthesia?

Area of Science:

• Anesthesiology
• Pharmacology

Background:

• Traditional anesthetics like propofol and etomidate have limitations.
• There is a continuous need for safer anesthetic agents with better hemodynamic stability and recovery profiles.

Purpose of the Study:

• To review recent advancements in intravenous anesthesia.
• Focus on novel agents including remimazolam, ciprofol, etomidate analogues, and neurosteroids.
• Discuss contemporary approaches to monitoring anesthetic depth.

Main Methods:

• Literature review of recent advances in intravenous anesthesia.
• Focus on pharmacological properties and clinical applications of new agents.
• Examination of technological advancements in anesthesia delivery and monitoring.

Main Results:

• Remimazolam offers ultra-short action, hypnosis, reduced cardiovascular depression, and reversibility.
• Ciprofol shows high potency, better injection tolerance, and a favorable hemodynamic profile.
• Novel etomidate analogues aim to minimize adrenal suppression, while neurosteroids provide rapid onset and stable effects.
• Computer-assisted delivery systems and AI-driven monitoring enhance precision and responsiveness.

Conclusions:

• Intravenous anesthesia is shifting towards personalized, computer-assisted delivery.
• Novel agents with favorable pharmacokinetics are improving safety and efficacy.
• These trends indicate safer anesthesia management and foster continued innovation.
