In vitro, ex vivo and animal studies on cutaneous injuries due to sodium hydroxide are presented in this poster. These studies confirm the need of a fast and effective decontamination in order to prevent or limit lesions spreading. Presented results support previous studies and the clinical use of the Diphoterine® solution as a decontamination solution in cases of cutaneous sodium hydroxide splashes.
