by Overview of Sevorane
Sevorane is a haloalkyl ether used for inhalational induction and maintenance of general anesthesia. It is a colorless, sweet-smelling liquid that evaporates quickly at room temperature allowing it to be easily administered via respiratory routes. Being highly volatile, Sevorane produces rapid induction and recovery from anesthesia.
Chemical and Pharmacological Properties
Structurally, Sevorane is a fluorinated methyl isopropyl ether. The addition of trifluoromethyl and fluorine groups allows Sevorane to vaporize faster than its predecessor halothane, making it quick acting. At clinical concentrations between 1-3%, it acts by potentiating the inhibitory effects of gamma-aminobutyric acid (GABA) on neurons in the brainstem and spinal cord. This depresses neural activity in these regions inducing unconsciousness without significant respiratory or cardiovascular depression. While Sevoflurane offers several clinical benefits.
Advantages over Other Inhalational Agents
One of the most significant advantages of Sevorane is its low pungency and nonirritating nature. Inhalation of Sevorane produces little coughing, breath-holding or laryngospasm compared to halothane, enflurane or isoflurane. This facilitates smooth inductions, especially in children and elderly patients. Sevorane also has a sweet, nonirritating odor that many patients describe as pleasant.
In addition, the rapid metabolism of Sevoflurane yields carbon dioxide and inorganic fluorides as end products. This confers a wider therapeutic window with a lower risk of nephrotoxic, hepatotoxic or malignant hyperthermia effects versus halothane or enflurane. Recovery from Sevorane anesthesia is also very fast, typically within 10 minutes of stopping its administration. This enables quick turnaround times and early patient discharge from postoperative care units.
Applications in Clinical Practice
Due to the above attributes, Sevorane has become a popular agent for general anesthesia, especially in pediatric and ambulatory surgical settings. It is commonly used for both induction and maintenance of anesthesia especially for short surgical or diagnostic procedures like endoscopy, interventional radiology, ophthalmic surgery, orthopedic procedures and laparoscopic surgeries.
Sevorane provides excellent laryngeal mask airway and endotracheal intubation conditions at 2-3 minimum alveolar concentration (MAC). This allows smooth induction of anesthesia even in apprehensive patients. Its non-pungency also diminishes the coughing and gagging often associated with endotracheal intubation, making it ideal for airway management.
In pediatric populations, Sevorane has multiple advantages like a pleasant odor, less irritability on induction and rapid awakening. This promotes better cooperation and a less traumatic experience for young children undergoing procedures. Elderly and high-risk patients also recover faster from Sevorane than other agents, helping reduce postoperative complications.
Perioperative Considerations
While Sevoflurane offers several clinical benefits, certain cautions must be observed during its use. Like other potent inhaled anesthetics, Sevorane is highly flammable when mixed with high concentrations of oxygen. Strict adherence to fire safety protocols is necessary, especially when using electrocautery or lasers near the airway during anesthesia.
Other rare but serious side effects reported include malignant hyperthermia, arrhythmias and awareness under anesthesia. Careful monitoring is indicated, particularly in susceptible individuals. Sevorane may also cause a transient rise in serum inorganic fluoride levels but the clinical significance remains unclear. Postoperative nausea and vomiting occurs in 10-30% of adult patients and appropriate prophylaxis is advised.
Lastly, the environmental impact of potent inhalational agents must be considered. Though Sevorane breaks down quickly after use, trace amounts released into operating room air contribute to global warming. Its high vapor pressure requires vaporizer changes more frequently than other agents as well. Newer, low-flow anesthetic techniques help minimize Sevorane waste and costs.
Sevoflurane has become a mainstay of general anesthesia practice due to its rapid onset/offset, nonpungency and favorable hemodynamic stability profile. When used judiciously with appropriate precautions, it provides safe, smooth and fast inductions together with early recovery characteristics preferred for ambulatory and pediatric surgeries. Ongoing research also explores novel applications of this versatile inhalational anesthetic.
