[Comparative evaluation of anesthesia with etomidate and propanidid in patients undergoing electric cardioversion].

Cardioversion is one of the most effective treatment in cardiac arrhythmias. However, this technique is painful it requires proper anaesthesia assuring stable circulatory and respiratory functions. The authors compared two anaesthetics: etomidate and propanidid. No significant difference in their effects on both circulation and respiration has been noted. Some differences between both drugs in the produced adverse reactions were however noted. Etomidate caused pain at the site of injection, propanidid allergic reactions in the form of skin rash.
