Snakebites in Hong Kong: How to face the possible changes?

Abstract

Introduction: Over the past years, the environmental and scientific changes have shaped the snakebite scenarios and will continue to do so. Their effects ahead are discussed. Incidence: Because of declining plant agricultural industry and rising urbanization, a falling incidence is reasonably expected in future. In order to maintain the knowledge and skills, training for clinicians will become more crucial. Venom detection kits: Kits for Naja atra and Cryptelytrops albolabris have been available overseas. Local data should be gathered regarding their clinical application. Antivenoms: The common local species covered by the haemotoxic and neurotoxic polyvalent antivenoms from Thailand is only Cryptelytrops albolabris. Introduction into Hong Kong is not recommended. Enzyme inhibitors: With an aim to improve the control of local injury that is unsatisfactorily accomplished by antivenoms, therapy with venom enzyme inhibitors is under research. Conclusion: A decreasing number of snakebite is anticipated. Venom detection kits should be explored for the use in appropriate cases.
