Oronasal fistulae
May be secondary to trauma, dental extraction or ruinous. Need surgical repair to stop foot materials impacting nasal cavity
Pre and post op considerations specific to oral surgery
Pre - flush mouth of debris
Post - ensure patient can’t eat / drink - food needs to be soft but easy firmed so easy to swallow. Feeding tube may be required.
Foreign body
Main sign is persistent or intermittent vomiting. May be removed endoscopically. May need surgery.

Are seizures more common in cats or dogs
Dogs
Normal cerebral activity
Neurones transmit info through chemical and electrical signals. This is regulated by large group of inhibiting cells called interneurones. If balance between excitation and inhibition input is altered a seizure occurs.
Seizure
Clinical manifestations of excessive abs or hypersyndrones. Usually self limiting neuronal discharges.
3 diagnoses seizure and definition.
Isolated seizure - lasting less than 3 mins and only occurs once.
Cluster seizure - 2 or more within 24 hours with complete recovery in between.
Status epilepticus - seizure lasting longer than 5 mins. 2 seizures without complete recovery in between. Neorological emergancy.

What when dose
Up to date body weight
If asymptomatic, unknown or low risk product - call VPIS
Symptomatic or known ingestion of high risk product - immediate vet attention
Owner instructions and advice when suspect poisoning
Owner should bring - product label or photo, sample of product. Approx time and quantity.
Advice - if dermal contamination prevent self grooming. Ensure other pets or children don’t have access. Don’t follow internet remedies
What to get while waiting for poisons patient to arrive
If dose of substance and bw already known then consult poisons service.
Prepare for triage and initial managed.
Get oneself, vet, hospital sheet, Cateter abs fluid therapy, oxygen, diagnostics samples, decontaminates, emetics
Managing poisons
Remove / eliminate toxin. (Induce emesid, gastric lavage, cutaneous decontamination,haemodilalysus)
Reduce ongoing absorption.
Dilute toxin.
Induction of emesis
Emesis empties 40-60% gastric contents. May enhance effectiveness if feed small meal prior.
Indicated within 2-3 hrs after oral ingestion if non corrosive intoxicant.
Contraindicated if intoxicant is corrosive/ irritant
Dogs - apomorphine sc
Cats - xylazine Im
Gastric lavage
Uncommon.
Known intoxication ingested within last hour and emesis unsuccessful or contraindicated.
Cutaneous decontamination
Wear appropriate ppe. Clip affected regions in long haired patients. Warm water. Mild shampoo / detergent. Avoid ocular contamination.
Reducing ongoing toxin absorption
Enteric absorbents
Intralipids.
Enteric absorbents
Reduce ongoing absorbing.
