[Nicolau syndrome after ketazon injection].

Nicolau syndrome is a rare complication, which occurs after intramuscular injections of various drugs, particularly antirheumatic drugs. During one year, the authors observed this syndrome in three patients, who had received intramuscular injections of Ketazon. The aetiology of the syndrome is not yet known, but it is often caused by accidental intraarterial injections of the drug. Since there is no specific therapy for the syndrome, the authors insist on the possibility of preventing it.
