Implication

Free iodine solutions damage conduction in dogs; precludes human use and leaves open safer intravital stains for conduction system identification.

Structured PICO

Does intravital staining with free iodine solutions safely identify the atrioventricular bundle during cardiotomy in dogs?

P
Population
Dogs undergoing cardiotomy
I
Intervention
Solutions containing free iodine
O
Outcome
Identification of the conduction system and interference with cardiac conductionsafety

While free iodine solutions can identify the conduction system during cardiotomy in dogs, they cause lasting damage to cardiac conduction, precluding their safe use.
