Lesson 1Principles of balanced anaesthesia and multimodal analgesia for dogs and catsThis section outlines principles of balanced anaesthesia and multi-way pain relief, combining sedatives, opioids, local blocks, and extras to lower gas needs, boost stability, and better comfort in dog and cat neuter patients in Botswana.
