Contraindications |
|
Previous hypersensitivity to sevoflurane or other halogenated
anesthetics |
|
|
Warnings/Precautions |
|
Malignant hyperthermia has been reported in susceptible patients, due to its
potential for fluoride nephropathy, renal function should be closely monitored,
similar to isoflurane, sevoflurane has the potential to increase cerebral blood
flow and intracranial pressure and therefore, must be used with caution in
patients with pre-existing increases in CSF pressure. |

|
Adverse
Reactions |
|
>1%:
Central nervous system: Agitation, headache, somnolence, dizziness, fever,
early emergence movement, hypothermia
Gastrointestinal: Nausea (25%) and vomiting (18%), increased salivation
Respiratory: Laryngospasm, airway obstruction, breath holding, increased
cough, apnea
Miscellaneous: Shivering |
|
|
Drug
Interactions |
|
CYP2E1 enzyme substrate |
|
|
Stability |
|
Store at controlled room temperature (15°C to
30°C); use cautiously in low-flow or closed-circuit
systems, since sevoflurane is unstable potentially toxic breakdown products have
been liberated |
|
|
Pharmacodynamics/Kinetics |
|
Sevoflurane has a low blood/gas partition coefficient and therefore is
associated with a rapid onset of anesthesia and recovery
Emergence time: 4 to 14 minutes
Metabolism: In the liver to inorganic fluoride, hexafluoroisopropanol and
hexafluoroisopropanol glucuronide |
|
|
Usual Dosage |
|
Induction: Usually administered in concentrations of 1.8% to 5% in
N2O/O2. It has also been given via the vital capacity
rapid inhalation technique as 4.5% in N2O/O2
Maintenance: Surgical levels of anesthesia can usually be obtained with
concentrations of 0.75% to 3% |
|
|
Monitoring
Parameters |
|
Blood pressure, temperature, heart rate, neuromuscular function, oxygen
saturation, end-tidal CO2 and end-tidal sevoflurane concentrations
should be monitored prior to and throughout anesthesia; the dose of sevoflurane
may be adjusted by monitoring blood pressure, since the depth of anesthesia is
inversely related to blood pressure in the absence of other
complications |
|
|
Dosage Forms |
|
Liquid for inhalation: 250 mL |
