Item Classification of gunshot foreign bodies migration(2024) Lurin, I.; Khoroshun, Eduard; Makarov, Vitaly; Nehoduiko, Volodymyr; Tertyshnyi, S.; Veryovkin, Igor; Vastyanov, R.The purpose of the study was to provide the classification features of the gunshot foreign bodies migration. We analyzed 90 cases of gunshot shrapnel blind wounds of different localization for a certain period, where there was a foreign body migration in different ways. The wounded which were admitted to the Military Medical Clinical Centre of the Northern Region of the Command of the Medical Forces of the Armed Forces of Ukraine, were examined by X-ray and, as indicated, using videoendoscopic methods. We distinguish the following classification features: the localization of the entrance hole; the place of migration initiation; the direction of migration; the number of foreign bodies; the structure of foreign bodies; the migration distance; the process of migration occurrence; the time of migration; the cause of migration; the frequency of migration; the foreign body fixation during migration; the volume of referral of migration surgical treatment. The identification of following three landmarks (the entrance hole, the place of migration starts and the place of detection), two stages (the wound channel and the migration corridor) and the direction of gunshot foreign bodies migration form a complete conception. The authors state that gunshot foreign bodies migration represents a separate type of a gunshot wound manifestation. The proposed original classification of gunshot foreign bodies migration allows to sort the data of clinical observations, which is of great importance for adequate and rapid diagnosis, determination of direct foreign body migration and its direction, and for effective treatment of gunshot wounds with phenomena of gunshot foreign body migrationItem Place and role of soft tissue ultrasound examination in tourniquet syndrome(2023-02-20) Лурін, I.А.; Хорошун, Едуард Миколайович; Негодуйко, Володимир Володимирович; Макаров, Віталій Володимирович; Тертишний, С.В.; Тірон, О.І.; Вастьянов, Р.С.The purpose of the study was to demonstrate and analyze the possibilities of ultrasound diagnosis of tourniquet syndrome. All wounded were admitted at the Military Medical Clinical Center of the Northern Region of the Command of the Medical Forces of the Armed Forces of Ukraine from advanced surgical groups at different times from the wound with an existing tourniquet on the limb at different times after the tourniquet was placed (from 5 to 72 hours, on average 8.2±0.6). There were 32 male wounded. The average age of the wounded was 39.4±2.6 years. According to the location of the tourniquet, the wounded are distributed as follows: shoulder – 5 (15.6 %), thigh – 24 (75 %), leg – 3 (9.4 %) patients. All the wounded underwent an ultrasound and elastographic examinations. We used an average result after 12 measurements of each muscle group. When studying the data of muscle elastography against the background of the existing tourniquet, a significant difference in the elastography indicators of healthy superficial and deep muscles being under the tourniquet due to compression is noted. Elastography indicators in deep muscles are always higher than in superficial muscles. Changes in muscle elastography are localized by the location of the tourniquet. The use of ultrasound examination of soft tissues in tourniquet syndrome has an additional character. According to the data of elastography of soft tissues in the case of tourniquet syndrome, it is possible to determine the extent of soft tissue damage, which is important for determining the size of surgical interventionItem Gunshot shrapnel wound of the thigh with damage to the superficial femoral artery (features of clinical manifestations, development of complications with late medical care and preservation of the limb)(2023) Lurin, I.; Makarov, Vitaly; Nehoduiko, Volodymyr; Smolianyk, Kostiantyn; Chobey, S.; Ott, O.The aim:To demonstrate the features of clinical manifestations and complications that occur with delayed medical treatment in cases of gunshot shrapnel through a wound of the thigh with damage to the superficial femoral artery. Materials and methods: The wounded individual, S., was 52 years old and had sustained a gunshot wound through a shrapnel wound of the left thigh with damage to the superficial femoral artery and soft tissue defect. Medical assistance was provided during the stages of medical evacuation. Results: The soldier sustained a gunshot wound through the upper third of the left thigh, resulting in damage to the vascular-nerve bundle and a soft tissue defect. First aid was provided at the scene, and surgical procedures were performed during the stages of medical evacuation, including primary surgical treatment of wounds in the upper third of the left thigh. On the second day following the injury, the wounded man was transferred to the Vinnytsia Military Medical Clinical Center and admitted to the vascular surgery department. After an ultrasound examination and repeated surgical treatment of the wound on the left thigh, damage to the superficial femoral artery was identified. Conclusions: The presence of features of blood circulation in gunshot wounds of the main vessels of the lower limbs can favorably affect the possibility of saving the limb, as evidenced by the case presented.Item Prospects of the high-speed multimedia data transmission technologies use in the structure of the system for providing aid to injured persons having a gunshot defect of soft tissues(2023) Lurin, I.; Khomenko, I.; Nehoduiko, Volodymyr; Tertyshnyi, S.; Weiss, B.; Kvasnevskyi, E.; Kvasnevskyi, O.The aim: To improve the results of providing medical care in the conditions of a fullscale war in Ukraine due to the use of medical technologies Materials and methods: From the first days, the Military Medical Clinical Center of the Southern Region provided medical assistance to the persons wounded as a result of the Russian Federation’s armed aggression. The presented multidisciplinary observation includes data received from 24.02.22 to 26.05.22. During this term, the multidisciplinary team assisted by the Teladoc Health system (the connection between the Charite Clinic, Berlin, and the MMCC of the Southern Region, Ukraine) performed 39 reconstructive and remedial operations in the MMCC of the Southern Region (Department of Surgical Infection). Results: It has been found that the implementation of differentiated surgical tactics (developed in cooperation between Charite clinics, Berlin, and MMCC of the Southern Region, Ukraine, using the Teladoc health system) in wounded patients with gunshot defects of soft tissues at the III and IV levels of medical care improves functional results, increases indicators of satisfactory from 46.9 % to 53.7 %, reducing the relative number of unsatisfactory from 18.8 % to 11.6 %. Conclusions: The information exchange in the Teledoc Health system is performed in telephone mode through protected communication channels. It enabled real-time treatment strategy recommendations and improved functional outcomes, increasing 2 the satisfactory rate from 46.9 % to 53.7 %, and reducing the relative unsatisfactory rate from 18.8 % to 11.6 %.Item Surgical tactics in fire kidney injury and the first experience in performing laparoscopic nephrectomy at the II level of medical support (role II) in combat conditions: Case report(2023-04-23) Gumeniuk, Kostyantyn; Lurin, Igor; Savytskyi, Oleksandr; Nehoduiko, Volodymyr; Makarov, Vitaly; Smolianyk, KostiantynIntroduction and importance: According to the data from the American Urological Association (AUA) and the European Urological Association (EAU) (2020), kidney is the most frequently damaged organ of the genitourinary system. Kidney damage occurs in approximately 5 % of injured people and accounts for 24 % of traumatic injuries to abdominal organs. Surgical treatment remains the gold standard in unstable patients with gunshot and stab wounds. Minimally invasive surgical treatment of kidney injuries, which is usually performed after laparoscopic diagnosis, at the II level of medical care becomes possible in the first hours after injury. Case presentation: We performed two laparoscopic nephrectomies caused by gunshot shrapnel damage to the kidney in a military mobile hospital at the II level of medical support. The time since the injury was 64 ± 16 min. The wounded were extubated after the operations, activated on the first day. In one case, the drain was removed on the third day, in the other – on the fourth day. During the monitored period (30 days) after the operation, there were no complications in both wounded. Clinical discussion: Laparoscopic nephrectomy in gunshot damage to the kidney was characterized by presence of a retroperitoneal tense hematoma. When opened, there were signs of bleeding from the kidney parenchyma, difficulty of anatomical visualization of anatomical structures - ureter, renal artery and vein. Conclusion: It is possible to perform endovideosurgical operations - laparoscopic nephrectomy in combat kidney injury at a military mobile hospital with available high-tech equipment at the II level of medical support (Role II), thus bringing highly specialized care closer to the wounded. We noted a better cosmetic effect after the laparoscopic operationsItem Termination transformation of the fragmentary capsule after a gunshot(2023) Lurin, I.; Makarov, Vitaliy; Nehoduiko, Volodymyr; Tertyshnyi, S.; Vastyanov, R.; Chobey, R.; Korol, S.By the method of Mikel Calvo in the modification of Davydenko S.I. by staining the carboxyl and basic groups of proteins, it was proven that the perversion of the synthesis and maturation of the connective tissue of the periosteal capsule is due to the presence of metal fragments, soot, chemicals and elements. In the capsule around the fragment located in the dermis, in the period from 4 months to 6 years, due to contact with large and small metal fragments, disorganization of collagen occurs with a decrease in the relative number of basic amino groups of proteins and an increase in the relative number of acidic proteins due to carboxyl and hydroxyl groups. Endless destruction of maturing connective tissue fibers by carboxyl groups of proteins and their predominance over basic groups contributes to tissue acidosis and enhances metabolic proteolysis processes, destroying surrounding tissues, preventing tissue healing and leading to final fibrosis and removal.Item Modeling of wound ballistics in biological tissues using engineering simulation software(2022-11-04) Tsymbaliuk, V.; Lurin, I.; Gumeniuk, K.; Herasymenko, O.; Furkalo, S.; Oklei, D.; Negoduyko, Volodymyr; Gorobeiko, M.; Dinets, A.Modern weapons cause severe damage, accompanied by high rates of complications and mortality. The investigation of such kinds of weapons is in high demand considering the ongoing active phase war against Ukraine since February 2022. In order to understand the pathological processes that occur in and outside the gunshot wound, we conducted an experimental study using mathematical simulation. The results presented in the article will help to choose the appropriate surgical management and improve the results of treatment. The aim of this study was to investigate and evaluate the damaging effect of a 5.45 mm 7N6M bullet and a 5.45 mm V-max expansive bullet using numerical modeling of wound canals in ballistic plasticine. The Ansys Explicit Dynamics engineering complex was used to simulate the dynamics of the bullet’s motion. The basic equations, solved by the explicit dynamic analysis, express the conservation of mass, momentum, and energy in Lagrange coordinates. Together with the material model and the set of initial and boundary conditions, they determine the complete solution to the problem. Taking into account that the initial velocity of the bullet is 1185 m/s at a mass of 3.9 g, we obtain energy 2740 J. All this energy acts at the area of the wound canal with a depth of 150 mm. Injury with a conventional 7N6M bullet is characterized by the fact that it passes through the block and loses only part of the kinetic energy. The simulation results showed that the velocity of the bullet at the outlet is 220 m/s. Taking into account the initial velocity of the bullet 918 m/s with a mass of 3.4 g, we obtain the kinetic energy acting on the walls of the wound canal with a depth of 200 mm of about 830 J. Mathematic analyses showed that the expansive bullet has a soft core that deforms and transfers all the kinetic energy to the tissues immediately after penetration into the tissues. The loss of kinetic energy of the bullet (ΔE, J) is defined as the difference between the kinetic energy at the time of injury (Ec, J) and the residual energy of the bullet when leaving the material (Er, J). Numerical modeling of wound ballistics in biological tissue simulators allows us to determine with high accuracy the features of wound canal formation and tissue response to damage of bullets having different kinetic energy, which contributes to the choice of adequate surgical management during surgery for gunshot wounds
