A MEMOIR of much interest and i'm |
portancc upon the use OF auasthetics
has been communicated to the Paris |
Academy of Science by Mons. Paul |
Bert. By experiment with different |
anfesthetic agents upon animals he has |
been able to ascertain in the case of each |
substance what is the quantity just suf- |
ficient to cause insensibility and how
much suffices to produce death. He |
finds the fatal dose of chlorform, ether, |
amylene, bromide of ethyl and chloride |
of ethyl to be always exactly double the |
an@sthetic dose. The range between |
these extremes Mons. Bert terms the
working zone, and he says that mixture
about the middle of this working zone.
properly administered, will produce a |
safe state of insensibility, which may be
maintained long enough for any surgical /
operation
