Anesthetic-Related Drugs Flashcards
Common cause of bradycardia and animals under anesthesia!!!!
Hypothermia
Anti-cholinergic agents
Are parasympatholytic and sympathomimetic!!!!
- Inhibit bradycardia from vagus stimulation
- reduce salivary and respiratory secretions
- mydriasis
- reduced salivation and resp secretions
- reduced G.I. motility
Why should you exercise caution with ace in aggressive animals
What other class of drugs relieves aggressive inhibition Is ace more clinically effective in dogs or cats. Effects
Removes fear of you, animal may attack
BZD
Dogs
Anti-emetic, mild antihistamine, tranquilizer
Is ace contraindicated in seizure history
T/F: BZD facilitate the onset & maintenance of sleep and are used as anticonvulsants
Sedation lasts longer than analgesia with which class of drugs
No
T
A2-agonist
Respiratory depression is rare in animals were given appropriate doses and are awake and in pain in which class of drugs
They can cause nausea and vomiting most commonly in which type of patient
Opioid analgesic agents
Non-painful and healthy
Recuvyra
Highly concentrated form of fentanyl intended to be applied to the skin on dorsal scapular area of dogs, four days with single application. Meant to treat postoperative pain
Remifentanil
Synthetic opioid that it has been used with propofol CRI to provide total IV anesthesia in dogs. Very rapidly recovery, no residual analgesia
Butorphanol
Primary partial kappa agonist. Good sedative, very poor analgesia. Good with visceral, not somatic pain (which originates from skin, muscle, or skeleton). Can be used to partially reverse opioid - VERY weak partial mu-agonist
Buprenorphine
In cats, well-absorbed thru buccal and sublingual mm. Primarily partial mu-agonist
Tramadol
Opioid metabolite in some species (cats, not dogs). Inappropriate as sole analgesia unless very mild pain
Why is ketamine useful for patients at risk for hypotension
It causes sympathetic predominance: cardiovascular stimulation, increased heart rate, cardiac output, blood pressure. Also preserves ventilators response to hypercapnia when used alone
Ketamine should be used with caution in which kinds of patients
Liver and renal; liver biotransformation in dog, largely excreted unchanged by the kidney in cats
Propofol
Contraindicated what kind of patient
Sedative-hypnotic Agent. No analgesia. No preservative, constituents support bacterial growth. Should be thrown out 6h after opening
CV
Repeated administration or CRI in cats: Heinz body production, anorexia, retching, lethargy, malaise, diarrhea
Etomidate
Utra-short acting, non-barbiturate hypnotic agent. Primarily used for induction in cardiac disease and C-sections in debilitated animals. No analgesia, poor muscle relaxation
Can cause myoclonus, propylene glycol vehicle
Alfaxalone
Has myocardial depressant effect
Apnea or Bradypnea,
Arrhythmias, hypertension, hypothermia possible
No Antimicrobial preservative. Do not mix with any other agents in syringe
