Gettler’s test is used to estimate the chloride content of the blood from both sides of the heart. It is a quantitative determination of the chloride content of the blood in the right and left ventricle of the heart. It is found to be of little value.
Various tests have been developed through the years to find out whether or not an individual has drowned. Essentially the most well-known is the Gettler chloride check,10 wherein blood was analyzed from the fitting and left sides of the center. If the chloride degree was much less on the fitting than on the left, the particular person was assumed to have drowned in saltwater. If it was elevated on the fitting facet of the center over the left, then one was considered coping with a freshwater drowning. Checks have additionally been carried out for different components within the blood, in addition to evaluating the particular gravity of blood in the fitting versus the left atria. The entire aforementioned tests are unreliable and of no assist in diagnosing drowning.A extra unique, although controversial, check includes the identification of diatoms within the tissue of drowning victims. Diatoms are microscopic unicellular algae various in dimension from 5 to greater than 500 pm. These organisms have a silica skeleton within the form of two valves. They’re discovered in every single place in all kinds of water (contemporary, brackish, and saltwater), on moist soil, and in the environment. Some authors contend that the identification of diatoms in human organs is evident proof of drowning, whereas others say that it isn’t attainable to return to this conclusion due to the widespread distribution of those organisms all through the atmosphere.11,12 The entire query revolves round whether or not diatoms are usually current in human organs, their density if current, and what varieties are current. Lung, liver, kidney, and bone marrow have been analyzed for diatoms and conclusions have been reached primarily based on the presence or absence of those organisms. Some medical professionals have discovered diatoms within the organs of non-drownings, whereas others haven’t.
If diatoms are current in a physique, there are three attainable methods they might have gotten there. First is by inhalation of airborne diatoms, second is by ingestion of fabric containing diatoms, and third is by aspiration of water containing diatoms, with subsequent circulation of those all through the physique. Complicating all that is the truth that diatoms are so ubiquitous that a number of the analyses could have been contaminated by the glassware and reagents used.
At present, individuals who use diatom evaluation are inclined to take care of closed organ programs, comparable to femoral bone marrow or an encapsulated kidney from a non-decomposed physique. Contact of the pattern with water is proscribed to triple distilled water. The devices are specifically cleaned to forestall contamination with diatoms. The fabric, comparable to bone marrow, is digested in concentrated acid. The deposit is examined with a regular microscope for the presence of the diatoms. The water wherein the person has allegedly drowned is sampled to see what kind of diatoms are current and a comparability is made between these within the water and people discovered within the physique. Whereas a optimistic comparability is useful, a adverse consequence doesn’t rule out drowning.
