Hi ! I injected by mistake a cow with calcium chloride subcutaneous(wich is for strict intravenous administration because it causes tissue necrosis). I injected 50 ml (10 ml in five different points,1ml=100mg calcium chloride),then i saw the label of the bottle that was mixed in between the calcium gluconate bottles. What is the worst thing that can happen to the cow? Thanks in advance for any advice!
