[Snakebite in Switzerland - a potentially life-threatening event?].

A 39-year-old healthy patient accidentally stepped barefoot on an adder and was then bitten into the foot. After initially only local complaints, severe systemic symptoms developed within 10-15 minutes with swelling of the lips and soft palate, recurrent vomiting, bradycardia, weakly palpable peripheral pulse, hypotension, dyspnea and intermittent somnolence. The potentially life-threatening consequences of this severe poisoning could be avoided by using adequate emergency measures and immediate intravenous administration of antivenin.
