Read the first 7 Anesthesia Management flashcards as text

  1. Which anesthetic agent is most appropriate for a patient with suspected increased intracranial pressure?

    Answer: Propofol

    Propofol decreases intracranial pressure and cerebral metabolic rate, making it preferable in patients with head trauma or intracranial disease.

  2. A cat anesthetized with isoflurane develops a heart rate of 240 bpm. Which drug is most appropriate to treat this tachycardia?

    Answer: Dexmedetomidine

    Dexmedetomidine causes bradycardia via alpha-2 agonism and can be used to slow an anesthetic-induced tachycardia in cats.

  3. What is the primary purpose of using a Bain circuit during small animal anesthesia?

    Answer: To allow non-rebreathing with high fresh gas flows

    The Bain circuit is a modified Mapleson D non-rebreathing system that uses high fresh gas flows to prevent CO2 rebreathing.

  4. During mask induction in a dog, the patient suddenly becomes apneic. What is the FIRST action the veterinary technician should take?

    Answer: Intubate and provide IPPV

    When apnea occurs during induction, the airway should be secured immediately with intubation and intermittent positive pressure ventilation initiated.

  5. Which of the following best describes balanced anesthesia?

    Answer: Combining multiple drugs at lower doses to achieve anesthesia with fewer side effects

    Balanced anesthesia uses combinations of drugs (analgesics, sedatives, inhalants) at lower doses to minimize adverse effects while maintaining adequate anesthetic depth.

  6. A ferret undergoing anesthesia begins to show signs of hypoglycemia. Which condition is most commonly responsible for this complication in ferrets?

    Answer: Insulinoma

    Insulinomas are extremely common in ferrets and cause excessive insulin secretion, leading to hypoglycemia especially under the fasting stress of anesthesia.

  7. Which monitoring parameter is MOST useful for detecting malignant hyperthermia early during anesthesia?

    Answer: End-tidal CO2

    End-tidal CO2 rises rapidly in malignant hyperthermia due to increased cellular metabolism, making capnography the most sensitive early indicator.
