Sevoflurane
別名: SevoFlo, Ultane, Petrem, Sojourn, Sevocris, Sevorane, Sevotek
**Sevoflurane** is a specialized anesthetic gas administered by your veterinarian during surgical or diagnostic procedures. * **Fast Acting**: It allows your pet to fall asleep very quickly and smoothly, which is especially helpful for pets that are stressed or difficult to handle. * **Rapid Recovery**: Because the gas leaves the body rapidly once turned off, your pet will likely wake up, stand, and be alert much sooner than with older anesthetics. * **Safety**: It is generally very safe and is often the anesthetic of choice for older pets, very young pets, or exotic animals because it is gentle on the cardiovascular system. * **Post-Anesthesia**: Your pet may still be slightly groggy or uncoordinated for a short period after coming home. Keep them in a safe, quiet, and warm environment until they are fully back to normal.

給藥方式
可能的副作用
- Dose-dependent hypotension
- Dose-dependent respiratory depression
- Gastrointestinal effects (nausea, vomiting, ileus)
- Myocardial depression and bradycardia (less than halothane)
- Malignant hyperthermia (rare but life-threatening)
- Temporary decreases in erythrocyte, white cell counts, and total protein in ferrets
- Agitation or excitement during rapid recovery
- Neonatal depression (crosses the placental barrier)
注意事項與禁忌
- Patients with a history or predilection towards malignant hyperthermia
- Known hypersensitivity to sevoflurane or other halogenated anaesthetics
- Known or suspected susceptibility to malignant hyperthermia
- > **WARNING: Compound A Formation** > Sevoflurane can react with desiccated (dried out) carbon dioxide absorbents to produce 'Compound A', a known nephrotoxin. Always ensure CO2 absorbents are fresh and avoid using extremely low oxygen flow rates (< 500 mL/min). * **Rapid Action**: Because of its rapid onset, use extreme caution not to overdose during the induction phase. * **Rapid Recovery**: Animals (especially large animals like horses) may wake up abruptly. Appropriate sedation during the recovery phase is critical to prevent injury. * **Neurologic/Renal Disease**: Use with caution in patients with increased CSF pressure, head injury, or renal insufficiency. * **Species Specifics**: * **Rabbits**: Can cause breath holding and struggling; premedication and close observation are required. * **Guinea Pigs**: May have a low margin of safety. * **Geriatric Patients**: May require lower concentrations of inhalation anesthetic.
藥物相互作用
- Aminoglycosides, Lincosamides: May enhance neuromuscular blockade
- Barbiturates (phenobarbital, pentobarbital): May increase concentrations of inorganic fluoride
- Non-depolarizing neuromuscular blocking agents (atracurium, pancuronium, vecuronium): Additive neuromuscular blockade may occur
- Isoniazid: May increase concentrations of inorganic fluoride
- Midazolam: May potentiate sevoflurane effects; decrease MAC
- Opiates: May potentiate sevoflurane effects; decrease MAC
- St. John's Wort: Increased risk for anesthetic complications; recommend discontinuing 5 days in advance of surgery
- Succinylcholine: Sevoflurane may enhance effects
- Sympathomimetics (dopamine, epinephrine, norepinephrine, ephedrine): Sensitizes the myocardium to sympathomimetics (less than halothane); arrhythmias may still result
- Tramadol: May decrease MAC requirements
- Verapamil: May cause cardiodepression
