Veterinary Surgery, Anesthesiology and Radiology
Veterinary Surgery, Anesthesiology and Radiology
This domain tests surgical principles, asepsis, sutures, anaesthesia, local and general anaesthetic drugs, monitoring, and radiographic interpretation.
Core rules
- Asepsis: sterile instruments, sterile drapes, surgeon preparation, and patient skin preparation.
- Suture selection: absorbable versus non-absorbable; monofilament versus multifilament; tissue and tension guide choice.
- Anaesthesia: premedication, induction, maintenance, monitoring, and recovery. Assess depth by reflexes, respiration, and circulation.
- Local anaesthetics block sodium channels; toxicity causes CNS excitation then depression.
- Radiography: radiopacity depends on tissue density; use orthogonal views; contrast studies need correct timing.
Worked example
A dog has a distended abdomen, retching, and a radiograph showing a gas-filled viscus with a folded appearance. Reasoning: gastric dilatation-volvulus is likely. Stabilise with fluids and decompression before surgery. Radiographs guide diagnosis, not replacement for resuscitation. Surgery fixes the stomach position and assesses viability.
Traps
- Using a non-absorbable suture in a contaminated hollow organ.
- Judging anaesthetic depth by one reflex only.
- Diagnosing from a single radiographic view.
- Ignoring local anaesthetic dose limits in small patients.
Exam focus
Justify suture, anaesthetic protocol, and imaging view by patient and procedure.
