DVM Anesthesia and Surgical Principles 4

Question 1

Which anesthetic drug causes a dose-dependent decrease in intracranial pressure and is preferred in patients with head trauma?

Accepted Answer

Propofol

Answer

Propofol decreases cerebral metabolic rate and ICP, making it preferred for induction in patients with head trauma or elevated intracranial pressure.

Question 2

The Pringle maneuver, used during hepatic surgery in large animals and dogs, involves:

Accepted Answer

Digital occlusion of the hepatoduodenal ligament to reduce portal and hepatic arterial flow

Answer

The Pringle maneuver occludes the hepatoduodenal ligament (containing the portal vein and hepatic artery) to reduce hepatic inflow and minimize hemorrhage during liver surgery.

Question 3

A ferret presents for adrenalectomy. Which anesthetic concern is most critical given common ferret endocrine disease?

Accepted Answer

Insulinoma-associated hypoglycemia requiring dextrose supplementation

Answer

Ferrets frequently have concurrent insulinoma, which can cause life-threatening hypoglycemia during the perioperative fast; blood glucose monitoring and dextrose supplementation are essential.

Question 4

Which hemostatic technique uses electrical current to coagulate vessels by converting electrical energy to heat?

Accepted Answer

Bipolar electrosurgery

Answer

Bipolar electrosurgery passes current between two forceps tips through tissue, generating heat that denatures protein and seals vessels with minimal lateral thermal spread.

Question 5

Which of the following best describes balanced anesthesia in veterinary patients?

Accepted Answer

Combining multiple agents at lower doses to achieve hypnosis, analgesia, and muscle relaxation while minimizing side effects

Answer

Balanced anesthesia uses multiple drug classes (e.g., opioids, sedatives, local anesthetics, inhalants) at individually lower doses to achieve all anesthetic components while reducing adverse effects of any single agent.
