| Tóm tắt: | Many textbooks assume that vital signs and normal values are the same the
world over. This is, broadly, not very helpful. This chapter will give a very
broad range in tabular form so that the reader can adapt this book by adding
narrower ranges for the environment of the individual’s practice and from
the laboratory available. The term ‘reference range’ is now widely used,
rather than normal range. Classically, a normal animal is said to be within the
95% normal range. By definition, 5% of normal animals will not appear to be
normal. Thus, if 20 tests are carried out, every animal is likely to have one
value outside the normal range. Therefore there is a strong argument for
carrying out only specific tests for the parameters in which the clinician is
particularly interested. Laboratories on the whole do not like this arrangement, as they favour a blanket approach, which they find easier and cheaper.
Clinicians are urged therefore to work closely with their particular laboratory
so that a compromise regarding cost and relevance is reached.
The author is well aware that getting samples to laboratories will not be
easy or quick in many parts of the world. High temperatures are likely to be a
problem. The logistics should be considered with the laboratory. Fresh samples are likely to be the most difficult, so swabs for bacteriology in transport
medium should be taken. Bacteria can be plated out and grown in the field.
Only then can they be submitted for identification. Equally, smears can be
made and microscopic evaluation can carried out in the field after appropriate staining. These slides then can easily be referred to a more experienced
pathologist. Antibiotic sensitivity testing can easily be carried out in the field.
Relevant antibiotic testing discs can be used. There is little point in knowing
the sensitivity of an isolated organism to an antibiotic that is not available. |
