Pain Management and Analgesia

Short answer

Pain Management and Analgesia is 10 of the 150 scored VTNE items. It covers recognising and scoring pain across species using validated scales, multimodal analgesia, the analgesic drug classes and their effects and contraindications, local and regional techniques, pre-emptive analgesia, and non-pharmacological comfort measures for hospitalised patients.

Why it matters on this exam

Pain items test observation as much as pharmacology: the exam wants the technician who notices the change in posture and reports it.

Key concepts

Recognition: species-specific behaviour — cats often withdraw and stop grooming rather than vocalise; dogs may guard or show altered posture; use a validated scale consistently rather than a personal impression.
Multimodal analgesia: combining drug classes that act at different points so each can be used at a lower dose.
Drug classes: opioids (and their respiratory and gastrointestinal effects), NSAIDs (renal perfusion and gastrointestinal risk; never combine with corticosteroids), alpha-2 agonists (cardiovascular effects), ketamine and local anaesthetics.
Pre-emptive analgesia: giving analgesia before the painful stimulus reduces the total requirement.
Non-pharmacological: bedding, positioning, warmth, quiet, and gentle handling are part of the plan, not an afterthought.

Common mistakes

Concluding a quiet cat is comfortable.
Giving an NSAID to a hypotensive or dehydrated patient, risking renal injury.

Worked example

A cat two days post-surgery is eating but sits hunched and has stopped grooming. Those are pain behaviours in the species; scoring with a validated feline scale and reporting for an analgesia adjustment is the appropriate action.

Original practice questions

Pain Management and AnalgesiaDifficulty 2/5

A cat two days after surgery is eating but sits hunched and has stopped grooming. How should this be interpreted?

ANausea from the anaesthetic that requires an antiemetic instead
BNormal postoperative behaviour, since the cat is still eating willingly
CLikely pain, since hunching and reduced grooming are feline pain behaviours
DStress from hospitalisation that will resolve once the cat goes home

Show answer and rationale

Correct: C. Cats express pain through posture and withdrawal from normal behaviours such as grooming, often while continuing to eat. A validated feline pain score and a report for analgesia adjustment are indicated.

B — Eating does not exclude significant pain in cats.
D — Assuming stress delays analgesia the cat may need.
A — Nausea usually reduces appetite, which is not the case here.

Pain Management and AnalgesiaDifficulty 3/5

Which patient factor is the strongest contraindication to an NSAID?

AA mild elevation in liver enzymes noted on a routine screening panel
BConcurrent administration of an opioid for multimodal pain control
CAdvanced age alone in an otherwise healthy and well-hydrated patient
DHypotension or dehydration, because renal perfusion depends on prostaglandins

Show answer and rationale

Correct: D. NSAIDs inhibit prostaglandins that maintain renal perfusion during hypotension, so a dehydrated or hypotensive patient is at real risk of renal injury. Opioid co-administration is standard multimodal practice.

A — Mild enzyme elevation warrants caution but is a weaker contraindication.
B — Opioids and NSAIDs are commonly combined deliberately.
C — Age alone is not a contraindication.
