Indicators of X-ray fluorescent intensity in the content of captules of metal fragiles of soft tissues in injuries with explosive and fire-fire

Abstract

Background. Diagnosis of metal fragments in the soft tissues of the wounded is based on examination, history, data of radiographic and ultrasound examinations, wound revision. Errors in the diagnosis and treatment of gunshot wounds are due to the complexity of the mechanism, the combined nature of the injury and the inconsistency of seemingly minor changes in severe intracavitary and intratissue damage. One of the new technologies for deepening scientific knowledge is a modern method of X-ray diffractometry using X-ray phase analysis, which is effectively used in the study of metals. Taking into account the metal composition of most final metal fragments of explosive and refractory genesis and the possible diffusion of metal elements into the surrounding capsule, this method is adapted and used to study capsules of metal fragments of explosive and refractory genesis. The purpose of the study: to determine and analyze the intensity of X-ray fluorescence of the contents of the nano-impurities of capsules of metal fragments of soft tissues of explosive and refractory genesis. Mate­rials and methods. As a material for the study of X-ray fluorescence intensity of the nano-impurity content, soft tissues removed surgically together with an encapsulated metal fragment of explosive and fire-fighting genesis were used in 36 wounded in the period from 2 months to 23 years after wounding in a military medical clinic. The center of the Northern region of the Ministry of Defense of Ukraine and the State Institution “IZNH them. V.T. Zaitseva National Academy of Medical Sciences of Ukraine”. Results. Accor­ding to the results of the study of the intensity of X-ray fluorescence of nano-impurities, 3 phases of encapsulation of metal fragments in the soft tissues of the wounded were determined on the basis of elemental, structural, cellular, tissue and clinical data: active dynamic changes, transient phase, unstable equilibrium their absence in most clinical cases. Conclusions. 3 phases of encapsulation of metal fragments in soft tissues of wounded were determined on the basis of elemental, structural, cellular, tissue and clinical data: active dynamic changes, transitional phase, unstable balance, which reflect the main mechanisms of complications and their absence in most clinical cases.
