The case of a child who presented with severe rhabdomyolysis associate
d with renal failure after a viper bite is reported. Rhabdomyolysis is
a serious complication resulting from systemic envenomation and is un
common after viper bites in Europe. It may be due to oedema, myotoxic
agents and haemorrhagic factors and may be responsible for two types o
f potentially fatal complications, i.e, acute renal failure and hyperk
alaemia. The present case highlights the need to investigate routinely
for rhabdomyolysis after viper bites. Antivenom therapy is recommende
d as soon as signs of envenomation are present, without waiting for th
e onset of complications.
