Mnemonic for Sevoflurane
SEVOFLURANE
Sweet-smelling: Sevoflurane has a pleasant odor.
Excellent induction: It is commonly used for inhalational induction, especially in children.
Volatile: Sevoflurane is a volatile liquid.
Oxygenation: It is used for maintenance of general anesthesia.
Fluorinated: Sevoflurane is highly fluorinated.
Low solubility: It has low blood solubility.
Ultane: Another name for sevoflurane is “Ultane.”
Recommended fresh gas flow (FGF): Adequate fresh gas flow is recommended during administration.
Anesthesia: Sevoflurane is used for general anesthesia.
Non-irritating: It is non-irritating to the airways.
Efficient: Sevoflurane provides efficient and rapid induction and recovery.
Sevoflurane is a commonly used inhalation anesthetic agent, and understanding its properties and clinical applications is crucial for anesthesia board exams. Here are some key points to help you review:
Pharmacology and Mechanism of Action
- Blood-Gas Partition Coefficient: Sevoflurane has a low blood-gas partition coefficient, which allows for rapid induction and recovery from anesthesia.
- MAC (Minimum Alveolar Concentration): The MAC of sevoflurane is around 2%, making it a potent anesthetic.
Clinical Uses
- Induction and Maintenance: Sevoflurane is used for both induction and maintenance of general anesthesia. It is particularly favored for pediatric anesthesia due to its non-irritating properties.
- Recovery Profile: Compared to isoflurane, sevoflurane provides a faster recovery, with shorter times to emergence, response to commands, and orientation.
Side Effects and Considerations
- Cardiovascular Stability: Sevoflurane is generally well-tolerated with minimal cardiovascular effects, making it suitable for patients with cardiovascular concerns.
- Organ Protection: Emerging studies suggest potential benefits in organ protection and reduced postoperative cognitive dysfunction.

SEVO:
S: Smooth induction and recovery
E: Efficient (low blood-gas partition coefficient)
V: Versatile (used in both adults and children)
O: Outpatient friendly (suitable for outpatient procedures due to rapid recovery)
Another mnemonic for sevoflurane:
“SEVO: Sweet Smell, Easy Ventilation, Very Fast Onset”
Sweet Smell: Sevoflurane has a pleasant, non-pungent odor, making it ideal for inhalation induction, especially in children.
Easy Ventilation: It is a bronchodilator, which helps in maintaining smooth ventilation.
Very Fast Onset: Sevoflurane has a rapid onset of action, making it effective for quick induction.
