Tierärztliche Vereinigung für Tierschutz Expert Information Committee on Anaesthesia of GV-SOLAS Supported by The working group 4 of TVT (German veterinary association for animal welfare) Pain management for laboratory animals Status: May 2015 This current recommendation is an up-to-date version of the first recommendation of the Committee on Anaesthesia of GV-SOLAS issued in 2002. It was reviewed and revised in 2015 by the Committee on Anaesthesia of GV-SOLAS: Julia Henke, Biberach Jörg Haberstroh, Freiburg Martin Sager, Düsseldorf Kristianna Becker, Heidelberg Eva Eberspächer, Wien Alessandra Bergadano, Basel Daniel Zahner, Giessen Margarete Arras, Zürich and is backed by the working group 4 of TVT (German veterinary association on animal welfare). This recommendation is intended for licence applicants, animal welfare officers, and authorities. Its purpose is to support work practices that maintain animal welfare standards. Pain relief methods are constantly evolving (e.g. new analgesics, application methods and intervals, dosages). It is everyone’s responsibility to be informed about current standards and most re-cent developments in pain treatment for laboratory animals.
