Desflurane
Also known as: Suprane
Desflurane is an inhaled anesthetic gas used to keep your pet asleep and pain-free during surgery. * **Rapid Wake-Up:** Its primary advantage is that it leaves the body very quickly once the vaporizer is turned off, allowing your pet to wake up from anesthesia much faster than with older anesthetic gases. * **Pain Management:** Because your pet will wake up so quickly, the veterinary team will ensure that injectable pain medications are given *before* the gas is turned off, so your pet wakes up comfortable and pain-free. * **Safety:** It is considered very safe and places minimal stress on the liver and kidneys.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.
What it is used for
- General Anesthesia (Clinically useful concentrations)
- General Anesthesia (Emergency patients)
- General Anesthesia (Following IV induction)
- General Anesthesia (Clinically useful concentrations)
- General Anesthesia (Emergency patients)
- General Anesthesia (Following IV induction)
How it is given
Possible side effects
- Hypotension (dose-dependent)
- Respiratory depression (dose-dependent)
- Respiratory irritation and salivation (especially with mask induction)
- Sympathetic stimulation (tachycardia/hypertension) with rapid increases in concentration
- Malignant hyperthermia (in susceptible individuals, though incidence may be lower than other halogenated agents)
- Transient increases in glucose and white blood cell count
Cautions & contraindications
- Hypersensitivity to desflurane or other halogenated anesthetic agents
- History of or predilection towards malignant hyperthermia
- > **Rapid Recovery Warning:** Because recovery is exceptionally fast, patients may wake up in pain if perioperative analgesics are not administered proactively. Ensure appropriate analgesia and sedation are on board before discontinuing the gas, particularly in large animals. * **Induction:** Due to its rapid action, use caution not to overdose during the induction phase. * **Neurologic Patients:** Use with caution (weigh benefits vs. risks) in patients with increased CSF pressure or head injury. * **Compromised Patients:** Geriatric or critically ill animals typically require lower concentrations of inhalation anesthetics. * **Occupational Safety:** NIOSH recommends workers should not be exposed to ceiling concentrations > 2 ppm over a 1-hour sampling period.
Drug interactions
- ACE Inhibitors or other hypotensive agents: Concomitant use may increase risks for severe hypotension.
- Non-depolarizing neuromuscular blocking agents: Additive neuromuscular blockade may occur.
- Succinylcholine: May induce increased incidences of cardiac effects (bradycardia, arrhythmias, sinus arrest, apnea) and trigger malignant hyperthermia in susceptible patients.
