Here’s an excellent, free downloadable first aid resource designed for ships at sea where there is no doctor present. As expected, it is mostly aimed toward the seafarer, but much of the advice could be used in any type of expedition.
Fishermen are particularly prone to infections of the hands
and fingers because of their working environment and the
things that they are required to handle during their work.
For instance, they may be injured by fish spines and bones, by
broken ends of warps and many other things. Minor cuts and
grazes often go unnoticed at the time of injury. Bacteria are
carried into these wounds from fish slime and guts and also
from pieces of metal etc. Infection then develops with
inflammation of the infected area and the formation of pus.
Prevention is always better than cure and it is
recommended that Chlorhexidine Gluconate 20%
(HIBISCRUB) is used to wash hands and forearms after
handling fish of any kind. The Hibiscrub can be used as a soap
or in solution.
