In one dog, seizures kept recurring after periods of successful control following administration of propofol . Another dog with continuing seizures resistant to barbiturate therapy died following administration of propofol.
What are side effects of propofol in dogs?
Conclusions: Respiratory depression and apnea are the most likely adverse effects induced by i.v. administration of propofol to dogs. Propofol administered i.v. at a rate of 20 mg/kg/10 s induces minimal cardiovascular depression at dosages in excess of the apneic dosage.
Does sedation cause seizures in dogs?
Other rare complications of anesthesia include organ system failure (such as kidney, liver or heart failure), visual impairment, clotting disorders and seizures . Your veterinarian will take every precaution to minimize these risks during your dog’s anesthesia.
What medications can cause seizures in dogs?
- Analgesics (Aspirin and Ibuprofen)
- Antidepressants (SSRIs and TCAs)
- Theophylline (asthma medication)
- Chlorpheniramine (antihistamine)
- 5-Fluorouacil (cancer medication)
- Beta-Blockers (cardiac medication)
Does propofol increase seizure threshold?
Higher doses of propofol in induction of anesthesia can lead to a more progressive rise in seizure threshold than lower doses of propofol .
Does propofol have anti seizure properties?
Abstract. Background: Propofol is a general anesthetic having good anticonvulsant properties , but is limited in antiseizure use because of its potent anesthetic/sedative properties.
Can anesthesia trigger seizures?
Rapid induction of anesthesia occasionally can be associated with one or more acute seizures . Propofol,13 flurane (a substitute for halothane),14 and benzodiazepines (especially lorazepam)15 seem to be the agents implicated most often.
Can a dog with seizures have anesthesia?
Anesthesia for patients with seizure disorders
Patients with chronic seizure disorders can present to veterinarians for anesthesia for unrelated conditions such as dental prophylaxis in day to day practice .
Did my dog have a seizure?

What causes seizures in senior dogs?
Senior dogs are more prone to kidney and liver disease. As either of those organs fail, toxins build up in their blood stream . When these toxins reach the brain, seizures can occur.

Stress Factors That Can Trigger Seizures in Dogs. Just like you would for yourself, you should always help your dog to avoid stress, as stress can also be a trigger of seizures in dogs . Stress is actually the number one cause of seizures in humans, but less prevalent in dogs.
Can you have seizures while sedated?
Even “nonconvulsant” anesthetic drugs occasionally cause seizures in subjects with preexisting epilepsy . These seizures most commonly occur during induction or emergence from anesthesia, when the anesthetic drug concentration is relatively low.
What type of seizure is status epilepticus?
A seizure that lasts longer than 5 minutes, or having more than 1 seizure within a 5 minutes period, without returning to a normal level of consciousness between episodes is called status epilepticus.
Does Trazodone help with seizures?
Trazodone hydrochloride, a triazolopyridine, is considered to have little effect on the seizure threshold .
Does propofol lower seizure threshold?
Propofol is the most frequently used hypnotic agent in ECT. It is also known that propofol reduces duration of seizures, however its effect on seizure threshold is controversial . Wang et al.
What drugs lower the seizure threshold?

Are seizures common after surgery?
1. Introduction. Acute postoperative seizures (APOS) are defined as ictal events occurring during the first week after resective surgery for drug-resistant focal epilepsy . 1, 2, 3, 4, 5 These seizures usually are of serious concern to patients and their families, as they suggest that surgery has failed.
What’s the difference between sedation and general anesthesia in dogs?
Sedation, together with analgesia, amnesia and muscle paralysis, is the end result of general anesthesia, which is an induced, reversible and controlled loss of consciousness . Sedation, on its own, is the depression of awareness, whereby a patient response to external stimuli becomes limited.
