Abstract:
Introduction: Diphoterine is an amphoteric, slightly
hypertonic, polyvalent, sterile water-based eye/skin
decontamination solution which combines passive flushing
with active chemical decontamination. Reviews were
published in French (Minaro et al, 2000) and Hall et al
(2002). Since that time, many more studies of Diphoterine
safety and efficacy, both pre-clinical and clinical, have
been performed. This review describes earlier studies and
details more current ones. Some of these were described in
reviews at the Medichem Conference, Basel, Switzerland,
2016, at the AMPAT Congress, Singapore, 2016, and the
AOHC Congress, Kaohsiung, Taiwan. Presented here are
new not previously presented data.
Materials and Methods: A review of all new data since
previous presentations was performed.
Results: Non-Clinical: In vitro/ex vivo comparative
decontamination studies with phenol (acid) and
tetraammonium hydroxide (TMAH) (base) have
been performed. In both cases, Diphoterine solution
decontamination was superior to water decontamination.
Clinical studies have included a 20-year chemically
exposed eye study from Germany in which Diphoterine
solution was found better than any other rinsing solution.
A multi-center, multinational clinical study from France
and Belgium showed the efficacy of Diphoterine solution
for decontamination of chemically exposed skin, eyes,
and oral membranes in the pre-hospital and emergency
department settings. Similar results were found in a clinical
study of occupational phenol exposure outcomes in Taiwan
and exposure to various various caustic substances in India.
Conclusion: Based on previously published/presented data
and data presented here, Diphoterine solution is a better
choice than potable water or other rinsing solutions for
first aid, pre-hospital, and emergency department (even if
delayed) decontamination of chemical eye/skin exposures.
