Remote intramuscular injection in unmanageable horses

INJECTABLE anaesthetics are usually given to horses by intravenous injection because this produces a faster onset of action and a more predictable effect compared with intramuscular administration. Drug doses are lower and so costs are reduced. Unfortunately, in some animals, it may not be easy or safe for a drug to be administered intravenously. In these circumstances, an alternative approach is required. This practice tip describes a remote intramuscular technique used by the author when direct injection is impossible.
