The big sleep3 July 2012 All zoo animals - and sometimes also wild animals- occasionally need veterinary treatment andanaesthesia is clearly required in many cases. Formost animals the procedures are well establishedbut for a variety of reasons it has proven difficultyto anaesthetize hippopotamuses. The thick skinand the dense subcutaneous tissue make it difficultto introduce sufficient amounts of anaesthetics andopioid-based anaesthetics often cause breathingirregularities and occasionally even death. Inaddition, the level of anaesthesia is only rarelysufficient to enable surgery to be undertaken: fewvets wish to be around when a druggedhippopotamus starts to wake up. Together with Thierry Petit from the Zoo de laPalmyre, France, and collaborators in Germanyand Israel, Gabrielle Stalder and Chris Walzer fromthe Research Institute of Wildlife Ecology,University of Veterinary Medicine, Vienna(Vetmeduni Vienna) have now developed a newanaesthetic protocol based on the use of two non-opiate drugs, medetomidine and ketamine.
