A farmer I was treating posed this question the other day, whilst I was giving him IM Tetanus Ig into the deltoid of his his non injured limb.
He questioned why I was using the non injured side, as traditionally in farming he had been taught to inject vaccines etc etc into the injured side.
My rationale explanation was around the circulatory compromise due to swelling and localised inflammatory response on the injured side that could cause inadequate perfusion of the vaccine.
Is my rationale wrong? Discussion please from fellow nurses!!
