The Use of Sevoflurane in Anesthesia A Comprehensive Overview
Sevoflurane is a volatile anesthetic agent widely used in both general and pediatric anesthesia due to its favorable properties. First introduced into clinical practice in the mid-1990s, sevoflurane quickly gained popularity for its effective anesthetic qualities, rapid onset and offset, and minimal side effects. This article explores the benefits, mechanisms, and considerations surrounding the use of sevoflurane in clinical anesthesia.
Mechanism of Action
Sevoflurane, chemically known as 1,1,1,3,3,3-hexafluoropropylene oxide, works by enhancing inhibitory neurotransmission and decreasing excitatory neurotransmission in the central nervous system (CNS). It primarily affects gamma-aminobutyric acid (GABA) receptors and the N-methyl-D-aspartate (NMDA) receptors, contributing to its anesthetic effects. The drug's low blood-gas partition coefficient allows for rapid induction and emergence, making it ideal for outpatient surgeries where quick recovery is essential.

Advantages of Sevoflurane
1. Rapid Onset and Recovery One of the most attractive features of sevoflurane is its quick action. Patients become unconscious within minutes after inhalation, allowing for efficient anesthesia induction. The rapid elimination from the body post-surgery minimizes recovery time, facilitating early discharge from the surgical facility.
2. Minimal Respiratory Irritation Unlike some older volatile anesthetics such as halothane and enflurane, sevoflurane has a pleasant odor and does not irritate the respiratory tract, making it suitable for use in children. Its low airway irritability reduces the risk of coughing or bronchospasm during inhalation.
3. Neuroprotective Effects Studies suggest that sevoflurane may have neuroprotective properties, which
