title: Occupational exposure to hydrazines: treatment of acute central nervous system toxicity.
abstract: Exposure to hydrazine and hydrazines' alkylated derivatives is an important occupational health issue, which will increase in significance as space applications increase. Despite their widespread usage as rocket fuels in manned and unmanned space and missile systems, serious exposures to hydrazines are rare. While a significant number of experimental studies were performed in the late 1950s through the mid-1960s, conflicting information exists concerning the most appropriate treatment for these exposures. A cross-sectional study evaluating the most common rocket fuels such as hydrazine; 1,1-dimethylhydrazine (UDMH); mono-methylhydrazine (MMH); and Aerozine-50 against the most commonly suggested therapies, such as pyridoxine, traditional antiseizure therapies, and arginine is needed to clarify the treatment implications for human exposure. Treatments that have been useful for hyperammonemic states, such as those for the six inherited urea cycle defects, have significant potential for the improvement of hydrazine exposure treatment.
