**七氟醚**是獸醫師在進行手術或診斷程序時使用的一種專業麻醉氣體。 * **作用迅速**：它能讓您的寵物非常快速且平穩地入睡，這對於容易緊張或難以保定的寵物特別有幫助。 * **快速甦醒**：因為一旦關閉氣體，它會迅速從體內排出，您的寵物會比使用傳統麻醉劑更早醒來、站立並恢復清醒。 * **安全性高**：它通常非常安全，且對心血管系統較溫和，常被作為老年寵物、幼年寵物或特殊寵物（特寵）的首選麻醉劑。 * **麻醉後注意事項**：您的寵物回家後可能仍會有短暫的昏沉或步態不穩。請讓牠們待在安全、安靜且溫暖的環境中，直到完全恢復正常。
劑量必須由獸醫依你寵物的個別情況決定。切勿在沒有獸醫指導下給予人類藥物或其他寵物的處方藥。

給藥方式
InhalationInhalational
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
