Poisoning in forensic against

If you suspect poisoning produce a forensic medical examination.
More often household poisonings (accidental), less frequently, cases of suicide and homicide. There are so-called medical poisoning (HCW misleads or gives them medicine exceeded in dose or instead of one medication more.)
For the diagnosis of poisoning the living and the dead bodies take into account the symptoms lifetime of the disease, documents, data examination of alive persons or autopsy of the corpse, as well as the circumstances of the case, the results of the inspection of the scene, features, revealed the remains of powders, tablets, liquids, which could be poisoning, the presence of vomitus, urine, and feces. These materials are taken away and sent for investigation.
At the showdown, you must pay attention to the changes of internal organs, are characteristic of certain toxic substances, and the smell characteristic of some poisons; for example, in the administration of dichloroethane smell of dried mushrooms, cyanide compounds - the smell of bitter almonds. To identify one or the other of the poison produce forensic chemical examination of the internal organs of the body. To study it is necessary to take gastric content, 1m small intestine content 1/3 of the liver to the gallbladder, kidney urine, part of the colon and, if necessary, and other organs. The material is put into a clean glass jar, which is sealed. They make stickers with the number of the act of opening, surname, name, patronymic of the deceased, the date of taking the material and signature of the expert. The material to be preserved not allowed.
The results of the forensic chemical research associate with the clinical picture of poisoning, data-mortem and other circumstances of the case. It cannot be based in the conclusions on results of the forensic chemical examination. The discovery of the poison in the body does not always indicate poisoning, because he could get into the corpse accidentally or as a result of taking drugs in life; as well as the absence of poison in the body does not reject poisoning, since the poisons in the body can break down and be. In addition to the forensic chemical research, manufacture spectral, microscopic, biological, pharmacological and other
The purpose of forensic medical examination to establish whether there has been poisoning. The remaining alive after poisoning determine the degree of gravity caused by poisoning harm, and in case of death - was not a poisoning caused his death.

Poisoning in forensic against. The object of forensic medical examination can be quite different in origin poisoning: household (accidents, suicide, homicide); medical (medical), accidentally encountered in medical practice in toxic influence of strong and poisonous drugs; professional, resulting in the violation of rules of labor protection and safety; food, observed in connection with the use of substandard food or products with nature poisonous.
For the diagnosis of poisoning forensic medical examination uses the circumstances of the case, lifetime poisoning symptoms, medical records, autopsy findings, the examination of alive persons, additional laboratory studies.
Furnished accidents sometimes directly or indirectly points to the Acting, for example concurrent illness and death of several people after being in the same room. In other cases, O. one can only suspect. Suspected of Acting in the course of the investigation it is extremely important to find out from witnesses and medical staff, and to fix the painful symptoms that was observed in diseased.
When entering the victim to a medical facility must be prepared history, fixing all the symptoms observed in a patient, as well as all the data related to his illness (from words of the patient or accompanying persons). For diagnosis of poisoning with medical institutions are of great importance timely laboratory of chemical research vomit, wash water, urine and feces, and spectral study (suspected Acting blood poisons). Chemical study of such objects is done in forensic laboratories. During their selection and direction for research must be careful and avoid accidental exposure to chemicals. At admission to the hospital together with the victims of dishes where the poison, or other objects, they must immediately be sealed and handed to the investigating authorities for referral to the judicial-chemical study. When reading the medical documents, the examiner should study the methods and means used in the treatment of a patient (stomach wash, the use of potent tools, and so on). This may be of importance for the evaluation of the results of chemical researches.
When non-lethal O. produce an examination of the injured to establish the fact of the former poisoning and its severity, using for this purpose the investigation data, medical records, lab tests and other
In fatal O. forensic medical study of the corpse is one of the most reliable and valuable evidence of the former O. O. Many toxic substances are characterized by morphological picture, on which you can install Acting in a certain poison (caustic alkalis and acids, arsenic, drugs mercury, cyanide compounds and others). O. some substances establish on the basis of smell found in the study of the corpse (in case of poisoning dichloroethane - the smell of dried mushrooms, cyanide compounds - the smell of bitter almonds and other).
In case of poisoning by some poisons (alkaloids, glycosides) morphological changes can be expressed not at all or to be atypical. To install O. these poisons during the autopsy impossible without the help of additional laboratory studies (chemical, spectral, microscopic, Botanical, pharmaceutical, microbiological and other). The greatest practical importance chemical study of the internal organs of the body. It is mandatory in all cases of suspected death from Acting

Objects allocated to the judicial-chemical study should be carefully Packed, sealed and labelled. The order of the objects on the research set out in the rules for exceptions and direction of various objects for the judicial-chemical studies. The results of the forensic chemical research facilities (both positive and negative) should be evaluated by a medical forensic expert from the point of view of their argumentation. Detection of toxic substances in the body is not yet a proof that the death was the result of poisoning by these poisons.
Found in the internal organs of the corpse toxic substances could hit it accidentally at the showdown could be used as drugs for the treatment of the victim, and so on, So a positive result of judicial-chemical studies can prove Acting only in cases, when the chemist detects such amount of this substance, which on the whole body is approaching lethal dose or exceeds it. The non-detection of toxic substances in the study of the internal organs of the corpse in itself is not proof of their absence, often with apparent poisoning of some poisons (surrogates alcohol - methanol, ethylene dichloride; alkaloids - morphine and its derivatives, barbiturates, and other) forensic chemical examination gives negative results. This is due to many reasons: toxic substances could decompose in the body, or to stand out from him, such as gastric lavage. Therefore, in all cases, the results of chemical researches should be carefully analyzed and compared with other data (the results of the autopsy, clinical picture, treatment methods and others), as well as with properties of very toxic substances.
If you suspect poisoning rules of forensic medical examination of the body provides a special procedure mortem (PP. 83, 84, 85, 86), as well as seizures and direction of the bodies of judicial-chemical study (see the Autopsy forensic). During the autopsy measures, warning accidental chemical substances on the body during and after opening (in case of repeated or additional autopsy). In the study of the corpse of great importance is attached to inspection service and the things that came in with the corpse, to identify them damage from corrosive substances, residues of poison in his pockets, and so on
