Flaxedil (gallamine triethiodide) was used extensively by crocodile farms and wildlife managers for the immobilisation of Saltwater Crocodiles (Crocodylus porosus). However, as it became increasingly difficult to obtain and the cost became prohibitive, alternative immobilising agents were sought. Preliminary testing suggested that Pavulon (pancuronium bromide) could be a potential replacement for Flaxedil. Extensive experimentation with juvenile C.porosus allowed dosage rates for Pavulon to be quantified. Dosage rates for immobilisation for 6-10h, for large crocodiles (>2.9m total length), were extrapolated from limited data, and continue to be tested. Nonetheless, Pavulon has proven to be a cheap, reliable immobilising agent for C. porosus.(1)
