Survival following Prehospital Traumatic Cardiac Arrest Resuscitation in the Israel Defense Forces: A Retrospective Study.

BACKGROUND: Prehospital traumatic cardiac arrest (TCA) is associated with a poor prognosis and requires urgent interventions to address its potentially reversible causes. Resuscitative efforts of TCA in the prehospital setting may entail significant resource allocation and impose added tolls on caregivers. The Israel Defense Forces Medical Corps (IDF-MC) instructs clinicians to perform a set protocol in the case of TCA, providing prompt oxygenation, chest decompression and volume resuscitation. This study investigates the settings, interventions, and outcomes of TCA resuscitation by IDF-MC teams over 25 years in both combat and civilian settings. METHODS: Retrospective study of the IDF-MC Trauma Registry between 1997-2022. Search criteria were applied to identify cases where the TCA protocol was initiated. A manual review of cases matching the search criteria was performed by two curators to determine the indications, interventions, and outcomes of casualties with prehospital TCA. Patients for whom interventions were performed outside of the TCA protocol, such as with measurable vital signs, were excluded. The primary outcome was survival to hospital admission, with the secondary outcome being return of vital signs in the prehospital setting. RESULTS: Following case review, 149 patients with prehospital TCA were included, with a median age of 21 (interquartile range 19-27). Eighty-four (56.4%) presented with TCA in military or combat settings, with gunshot wounds and blast injuries being the most common mechanisms in this group. For 56 casualties (37.8%), all components of the protocol were performed (oxygenation, chest decompression, and volume resuscitation). Five (3.4%) casualties had return of vital signs in the prehospital setting, but none survived to hospital admission. CONCLUSION: The prognosis of prehospital TCA is poor, and efforts to address its potentially reversible causes may often be futile. These notions may be further emphasized in military settings, where resources are limited, and extensive penetrating injuries are more common.

Lower Extremity Vascular Injury in the Pediatric Trauma Patient: Management and Outcomes at an Adult Level I Trauma Center.

BACKGROUND: Traumatic vascular injuries of the lower extremity in the pediatric population are uncommon but can result in significant morbidity. The objective of this study is to demonstrate our experience with these injuries by describing patterns of traumatic vascular injury, the initial management, and data regarding early outcomes. METHODS: In total, 506 patients presented with lower extremity vascular injury between January 1, 2009 and January 1, 2021 to Grady Memorial Hospital, an urban, adult Level I trauma center in Atlanta, Georgia. Thirty-two of the 506 patients were aged less than 18 years and were evaluated for a total of 47 lower extremity vascular injuries. To fully elucidate the injury patterns and clinical course in this population, we examined patient demographics, mechanism of injury, type of vessel injured, surgical repair performed, and early outcomes and complications. RESULTS: The median (interquartile range) age was 16 (2) years (range, 3-17 years), and the majority were male (n = 29, 90.6%). Of the vascular injuries identified, 28 were arterial and 19 were venous. Of these injuries, 14 patients had combined arterial-venous injuries. The majority of injuries were the result of a penetrating injury (n = 28, 87.5%), and of these, all but 2 were attributed to gunshot wounds. Twenty-seven vascular interventions were performed by nonpediatric surgeons: 11 by trauma surgeons, 13 by vascular surgeons, 2 by orthopedic surgeons, and 1 by an interventional radiologist. Two patients required amputation: 1 during the index admission and 1 delayed at 3 months. Overall survival was 96.9%. CONCLUSIONS: Vascular injuries as the result of trauma at any age often require early intervention, and we believe that these injuries in the pediatric population can be safely managed in adult trauma centers with a multidisciplinary team composed of trauma, vascular, and orthopedic surgeons with the potential to decrease associated morbidity and mortality from these injuries.

Antibiotic prophylaxis following low-velocity gunshot fractures: an updated review.

PURPOSE: Low-velocity gunshot fractures (LVGFs) are a common type of gunshot-induced trauma with the potential for complications such as infection and osteomyelitis. The effectiveness of antibiotic therapy in LVGFs remains uncertain, leading to ongoing debate about the appropriate treatment. In this review, we evaluate recent updates on the current understanding of antibiotic therapy in LVGFs, how previous studies have investigated the use of antibiotics in LVGFs, and the current state of institutional policies and protocols for treating LVGFs with antibiotics. METHODS: We conducted a review of PubMed, Embase, and Web of Science databases to identify studies that investigated the use of antibiotics in LVGFs after the last review in 2013. Due to the lack of quantitative clinical trial studies, we employed a narrative synthesis approach to analyze and present the findings from the included primary studies. We categorized the outcomes based on the anatomical location of the LVGFs. RESULTS: After evaluating 67 publications with the necessary qualifications out of 578 abstracts, 17 articles were included. The sample size of the studies ranged from 22 to 252 patients. The antibiotics used in the studies varied, and the follow-up period ranged from three months to ten years. The included studies investigated the use of antibiotics in treating LVGFs at various anatomic locations, including the humerus, forearm, hand and wrist, hip, femur, tibia, and foot and ankle. CONCLUSION: Our study provides updated evidence for the use of antibiotics in LVGFs and highlights the need for further research to establish evidence-based guidelines. We also highlight the lack of institutional policies for treating LVGFs and the heterogeneity in treatments among institutions with established protocols. A single-dose antibiotic approach could be cost-effective for patients with non-operatively treated LVGFs. We suggest that a national or international registry for gunshot injuries, antibiotics, and infections could serve as a valuable resource for collecting and analyzing data related to these important healthcare issues.

Infectious profiles in civilian gunshot associated long bone fractures.

PURPOSE: There is a paucity of literature on infections in civilian gunshot associated with long bone fractures with the reported rates ranging from 0-15.7%.This study aimed to investigate the rates of infection associated with long bone fractures caused by civilian gunshots. The specific objectives were to determine if certain extremities were at a higher risk for infection and to identify the types of bacteria present in these infections by analyzing culture isolates. METHODS: We conducted a retrospective review of consecutive patients aged 18-64 who sustained gunshot-associated long bone fractures at an urban Level I trauma centre from 2010 to 2017. Patient selection was based done through a institutional trauma centre database using international classification of diseases (ICD) 9 and 10 codes. We included patients who underwent surgical treatment, specifically fracture fixation, at our institution and excluded patients with fractures involving the pelvis, spine, foot, and hand. A total of 384 gunshot-associated long bone fractures in 347 patients were identified for analysis. Relevant patient-, injury-, and treatment-related variables were extracted from clinical records and radiographic reviews. Outcomes of interest included bony union, repeat operative procedures, and the development of deep infection. RESULTS: 347 patients with 384 long bone fractures were included. 32 fractures in 32 patients developed an infection for an incidence of 9.3% of patients and 8.3% of fractures. Gram-positive bacteria were present in 23/32 (72.0%) culture isolates, gram-negative bacteria in 10/32 (31.3%) culture isolates, and six infections were polymicrobial. Staphylococcus 16/32 (50.0%) and Enterobacter 6/32 (18.8%) species were the most common isolates. Of the Staphylococcus species, 5/16 (31.3%) were MRSA. Lower extremity fractures had a greater risk for infection compared to the upper extremity (11.7% vs 3.7% p < 0.01) and fractures that developed an infection had a larger average zone of comminution (63.9 mm vs 48.5 mm p < 0.05). CONCLUSION: This study investigated the rates of infection associated with long bone fractures caused by civilian gunshots. The overall infection rate observed in our series aligns with existing literature. Gram-positive bacteria were the predominant isolates, with a notable incidence of MRSA in our patient population, highlighting the need for considering empiric coverage. Additionally, gram-negative organisms were found in a significant proportion of infections, and a notable percentage of infections were polymicrobial. Our findings emphasize the importance of carefully assessing highly comminuted lower extremity fractures and implementing appropriate antibiotic coverage and operative debridement for patients with gunshot-related long bone fractures. While current prophylaxis algorithms for open fractures lack specific inclusion of gunshot wounds, we propose incorporating these injuries to reduce the incidence of infections associated with such fractures.

Pancreaticoureteric fistula following penetrating abdominal trauma: A Case Report.

Pancreaticoureteric Fistula (PUF) is a very rare complication secondary to penetrating abdominal trauma involving the ureter and pancreatic parenchyma. Pancreatic injuries carry h igh morbidity due to the involvem ent of surrounding structures and are d ifficult to diagnose due to thei r retroperitoneal location. A case of a patient is reported at Civil Hospital, Hyderabad who presented with a history of firearm injury and missed pancreatic duct involvement on initial exploration that eventually led to the development of Pan creaticoureteric Fistula. He was managed v ia p erc ut aneous nep hrostomy ( PCN ) for the right ureteric injury and pancreatic duct (PD) stenting was done for distal main pancreatic duct injury (MPD).

Prognostic Significance of Multifactorial Analysis in Complex Cervical Aero-Digestive Trauma Cases.

Background and Objectives: In the context of complex aerodigestive cervical traumas, the prognosis and outcome heavily depend on risk factors, particularly injuries to the larynx, trachea, major digestive tissues, cervical vertebrae, and vascular structures. With the increasing prevalence of trauma as a public health concern, there is a pressing need for epidemiological research and the implementation of preventative measures. The purpose of this research is to establish the profile of the predictable impact factors that determine the prognosis of patients with complex cervical trauma. Methods and Methods: The study group consisted of 106 patients with complex cervical trauma pathology developed by various mechanisms such as car accidents, home-related accidents, aggression, gunshot wounds, and self-inflicted attempts, resulting in hospitalization in the E.N.T. Clinic at "St. Spiridon" Iași Hospital, from 2012 to 2016; medical records were the source of the collected data. Results: Hemodynamic instability upon admission associated with age, muscle and laryngeal injuries, and anemia were identified as negative prognostic factors. Additionally, the utilization of imaging-based paraclinical investigations for diagnosing traumatic lesions emerged as a positive prognostic factor in managing this pathology. The management of penetrating cervical trauma remains a subject of debate, with some advocating for surgical exploration beyond the platysma layer in all cases, while others argue for a more selective conservative approach due to a high rate of negative explorations. Conclusions: The statistical evaluation of epidemiological, clinical, lesion, paraclinical, and therapeutic parameters is needed to establish predictable risk factors in the prognosis of complex aerodigestive cervical trauma.

Antibiotic Duration Following Abdominal Gunshot Injuries With Associated Pelvis or Spine Involvement: A 20-Year Single-Center Experience.

INTRODUCTION: Optimal antimicrobial prophylaxis duration following gunshot wounds (GSW) to the abdomen with an associated orthopedic fracture is unknown. This study evaluated the safety and efficacy of short versus long courses of prophylactic antibiotics following penetrating hollow viscus injury with communicating orthopedic fracture. METHODS: This retrospective study included adult patients admitted to the trauma service over a 20-y period who sustained an abdominal GSW with hollow viscus injury and communicating spine or pelvic fractures. Patients were stratified into cohorts based on prophylactic antibiotic duration: short course (SC, ≤48 h) and long course (>48 h). The primary outcome was the incidence of osteomyelitis and meningitis up to 1-y postinjury. Secondary outcomes included hospital length of stay and the incidence of multidrug-resistant organisms and Clostridioides difficile infections. Risk factors for osteomyelitis and meningitis were determined. RESULTS: A total of 125 patients were included with 45 (36%) in the SC group. Median prophylactic antibiotic durations were SC, 1 (interquartile range [IQR], 1-2) versus long course, 7 (IQR, 5-7) d (P < 0.001). There was no difference in osteomyelitis and meningitis incidence (2 [4.4%] versus 4 [5%], P = 0.77). Median hospital length of stay (7 [IQR, 6-11] versus 9 [IQR, 6-15] d, P = 0.072) and incidence of multidrug-resistant organisms (6 [13.3%] versus 13 [16.3%], P = 0.86) and Clostridioides difficile infections (0 [0%] versus 1 [1.3%], P = 0.77) were similar between groups. There were no independent risk factors identified for osteomyelitis or meningitis. CONCLUSIONS: A shorter course of antibiotic prophylaxis ≤48 h may be adequate following abdominal GSW that traverses a hollow viscus and results in pelvic fracture or spinal column injury.

Outcomes of Cardiac Gunshot Injuries Presenting at an Urban Trauma Facility in Johannesburg, South Africa.

BACKGROUND: Gunshot wounds to the heart are regarded as one of the most lethal penetrating injuries. There has been an increase in gunshot wounds to the chest in our institution in recent years. Injuries to the heart caused by gunshot wounds can be challenging, with patients arriving in hospital in different physiological states. We report our trauma unit's experience with civilian gunshot wounds to the heart. METHODS: A retrospective review from January 2005 till December 2018 of those 18 years of age and above who presented to our hospital with penetrating cardiac injuries over eight years was done. Those who presented with a carotid pulse and a cardiac rhythm were included in the study. Blood pressure of less than 90 mmHg was considered as haemodynamic instability. Demographics, physiological parameters, injuries sustained, preferred surgical access to the chest, and type of surgery were analysed. The complications during their hospital stay and outpatient clinic were documented. The incidences of in-hospital mortality were also noted. Descriptive statistics with STATA version 15 were conducted. A p-value of < 0.05 was considered statistically significant. RESULTS: A total of 37 patients were enroled in the study; four were excluded for incomplete data. All presented directly from the scene, with a median age of 30 (IQR 24-36). Haemodynamic instability was in 64% of the cases. The most common injured chamber was the right ventricle (75.7%). There were only two complications recorded; local wound sepsis and empyema. All survivors received a post-surgical echocardiogram. The overall survival rate was 18.9% (n = 7). Of the ten that required emergency room thoracotomy, only one survived to discharge. CONCLUSION: Gunshot wounds to the heart have a mortality rate greater than 80% in those arriving alive. Only one in ten of those who meet the strict criteria for emergency room thoracotomy survive hospitalisation. The local complication rate was low.

Continuum of Care: A Multiagency Approach to Seamless Warmed Prehospital Whole Blood Resuscitation of a Patient with Noncompressible Truncal Hemorrhage.

BACKGROUND: Prehospital transfusion capabilities vary widely in the United States. Here we describe a case of prehospital resuscitation using warmed, whole blood in a patient with penetrating torso trauma and associated hemorrhagic shock. CASE REPORT: A 68-year-old man sustained a single gunshot wound to the left chest and was found to have a shock index of 1.5 at the time of emergency medical services (EMS) arrival. Rapid peripheral intravenous and central venous access enabled the infusion of warmed low-titer O-positive whole blood. The EMS crew intentionally resuscitated the patient before managing the airway by means of rapid sequence intubation. An air medical services helicopter crew assumed patient care from the ground EMS crew and continued the warmed, whole blood transfusion during the flight to a regional Level I trauma center. The patient went directly to the operating room from the helipad, underwent definitive operative management, and was ultimately discharged home on hospital day nine. CONCLUSION: Early recognition of hemorrhagic shock, implementation of prehospital transfusion protocols that emphasize transfusion of warmed blood without interruption, and an organized, regional approach to trauma care are critical for improving patient survival.

Wandering projectile, a rare cause of acute urinary retention.

BACKGROUND: Urethral obstruction due to retained projectile migrating into the genitourinary system has rarely been reported. The literature describes two main methods of retained projectile removal from the genitourinary system: (1) spontaneous expulsion during voiding and (2) manual extraction due to urethral obstruction causing acute urinary retention. CLINICAL PRESENTATION: We present a case in which a 23-year-old man presented with acute urinary retention four days after suffering a gunshot wound to the right distal posterolateral thigh. A retained projectile eroded through the posterior wall (slightly to the right) of the bulbar urethra at the bulb, migrated through the urethra, and eventually became lodged in the external urethral meatus, causing obstruction and acute urinary retention. Subsequently, the foreign body was removed with manual extraction along with gentle external pressure under sedation and the patient was discharged with a 16 Fr transurethral catheter in situ to be kept for 1 week and removed after a week. CONCLUSION: The absences of signs do not always effectively rule out urethral or bladder injury. Urethral foreign bodies are not commonly encountered when they do the entry is usually the urethral meatus. However, the treating physician must that other mechanisms also exist especially in those with bullet injury to flank, abdomen, pelvis and even the distal thigh like our case.

The impact of colon injuries on the outcome of gunshot wounds to the abdomen.

PURPOSE: Factors predicting morbidity and mortality in patients with colon-related gunshot injuries and the management of these injuries are not always straightforward. This aimed to assess the impact of abdominal gunshot wounds with colonic injuries on patients' overall outcomes. METHODS: This cross-sectional prospective observational study compared patients with colon injuries and without colon injuries. Data was collected from admission, theatre and postoperative care. Patients were recruited between 1 January 2020 and 20 October 2021. RESULTS: Of 132 patients with abdominal gunshot injuries, 71 (54.0%) had colon injuries. The colon injury group had a higher incidence of laparotomy wound sepsis (p<0.0001), bullet exit wound infection (p<0.0001), tract necrotizing fasciitis (p<0.0001), relook laparotomies (p<0.0001) and a longer hospital stay (p<0.0001). Septicaemia (p=0.002) or anastomotic leak (p=0.041) was associated with a penetrating abdominal trauma index (PATI) ≥25. Most patients who developed tract necrotizing fasciitis did not have their tract debrided/ lavaged (p=0.004). The type of colon repair did not influence the length of hospital stay (p=0.688) or the development of a colon-related complication (p=0.578). Between 18 and 25 years (p<0.0001) and >2 organs injured (p=0.018) were associated with colon-related complications. Patients between 18 and 25 years were 4.748 times more likely to develop a colon-related complication (p=0.046). CONCLUSION: Gunshot wounds to the abdomen with associated colonic injuries had a worse outcome with an increased risk of developing wound infections. There is no difference in the operative management of colonic injury. Patients between the ages of 18 and 25 years or >2 organs injured are more likely to develop a complication.

Pseudoaneurysm of the brachial artery in an infant due to vaccination: a case report.

BACKGROUND: Pseudoaneurysm is a known complication of penetrating arterial injuries such as catheterization, gunshot wounds, and open fractures. Vaccination is an effective method for preventing multiple, serious, infectious diseases in children. Common adverse reactions related to vaccination include fever, swelling, redness, and pain. Brachial pseudoaneurysm after vaccination has not been previously reported. CASE PRESENTATION: Herein we describe a novel case of brachial pseudoaneurysm after vaccination in a child aged 1 year and 3 months. A pulsatile mass was formed in the medial left arm of the infant 10 days after vaccination at a community hospital and gradually grew larger. Preoperative images depicted an eccentric aneurysm in the brachial artery and a swirling flow pattern in the mass. The pseudoaneurysm was excised, and vein graft interpositioning was successfully performed. There were no short-term or long-term complications during the follow-up period. CONCLUSIONS: Brachial pseudoaneurysm is a rare complication of vaccination via intramuscular injection. Medical staff should avoid puncture wounds to the brachial artery during vaccination, especially in infants.

Gunshot injury to the colon by expanding bullets in combat patients wounded in hybrid period of the Russian-Ukrainian war during 2014-2020.

BACKGROUND: A gunshot wound to the colon is a frequent injury in armed conflicts. An example of a high-energy modern weapon is hollow-point bullets, which is associated with increased tissue damage and lethal outcome. The aim of this study was to evaluate gunshot injuries to the colon in combat patients and to assess the difference in clinical features of patients with colon injuries by hollow-point versus shape-stable bullets. PATIENTS AND METHODS: Analyses of clinical data were performed on 374 male soldiers from the Armed Forces of Ukraine with gunshot abdominal wounds with injury to the colon in East Ukraine between 2014 and 2020. Out of 374 injured, 112 (29.9%) patients were diagnosed with penetrating gunshot bullet wounds: 69/112 (61.6%) were injured by shape-stable bullets, and the hollow-point bullets injured 43/112 (38.4%) patients. RESULTS: More severe hemorrhagic shock stages were in patients injured by hollow-point bullets: shock stages III-IV was in 25 (58.1%) patients injured by the hollow-point bullets vs. 17 (24.6%) patients injured by shape-stable bullets (p = 0.0004). Left colon parts were more frequently injured as compared to the right colon side or transverse colon: 21 (48.8%) patients were injured by the hollow-point bullets (p < 0.0001), and 41 (59.4%) patients were injured by the shape-stable bullets (p = 0.032). A significant difference was identified for the frequent injury to the middle colon within the entire cohort (p = 0.023). Patients injured by the hollow-point bullets demonstrated a higher frequency of 3-5 areas of colon gunshot defects, which was detected in 18 (41.8%) patients injured by hollow-point bullets and none with shape-stable bullets injury (p = 0.0001). Colon Injury Scale (CIS) IV was detected in 7 (16.3%) patients injured by the hollow-point bullets as compared to 2 (2.9%) patients injured by shape-stable bullets (p = 0.011). Colostomy was performed in 14 (69%) patients injured by shape-stable bullets and in 12 (27.9%) patients injured by hollow-point bullets (p > 0.05). 15 (35%) patients died after injury by the hollow-point bullet, whereas 9 (13%) patients after damage by the shape-stable bullets (p = 0.0089). CONCLUSIONS: All patients should be suspected to have an injury by bullet with expanding properties in case of penetrating abdominal injury (absent of outlet wound) and careful revision of the abdomen must be performed to identify possible multiorgan injury as well as multiple gunshot defects of the intestine.

Important aspect of hypoglossal nerve injury following gunshot wound; Can the clivus has a role? A case report.

Cranial nerve palsies after gunshot injury are not uncommon. We report the mechanism of isolated hypoglossal nerve paralysis caused by a gunshot. We report a 74 years old patient in whom a bullet entered through the right nostril and then ended up right occipital condyle. The only neurologic deficit was tongue deviation which resolved in one week. The bullet was not removed. The effect of clival slope may have an importance in this type of injury.

Risk of Infection Following Gunshot Wound Fractures to the Foot and Ankle: A Multicenter Retrospective Study.

The purpose of this multicenter retrospective chart review was to describe demographics, fracture and wound characteristics, and treatments for foot and/or ankle fractures caused by gunshot wounds (GSWs) and identify factors that increase risk of infection in adults treated at 5 urban level 1 trauma centers in South and Midwest regions of the United States. A total of 244 patients sustained GSW-related fractures of the foot/ankle during 2007-2017, of whom 179 had ≥30 days of follow-up data after the initial injury. Most patients were male (95.1%; 232/244) with an average age of 31.2 years. On average, patients sustained 1.3 GSWs (range 1-5) to the foot/ankle. Most GSWs were categorized as low energy (85.1%; 171/201) and the majority (58.2%; 142/244) had retained bullet fragments. Antibiotics were administered at initial presentation to 78.7% (192/244) of patients and 41.8% (102/244) were managed operatively at the time of initial injury. Nerve injury, vascular injury, and infection were documented in, respectively, 8.6% (21/243), 6.6% (16/243), and 17.2% (42/244) of all cases. Multivariable analysis revealed that high-energy injuries and retained bullet fragments increased the risk of infection by 3-fold (odds ratio 3.09, 95% confidence interval 1.16-8.27, p = .025) and 3.5-fold (OR 3.48, 95% CI1.40-8.67; p = .008), respectively. Side of injury, primary injury region, and vascular injury were not significant predictors of infection risk. Further research should examine whether retained bullet fragments are directly associated with infection risk and support the development of guidelines regarding the management of patients with GSW-related fractures to the ankle/foot.

Improvement of speech by facial prosthesis in a midfacial defect with a gunshot injury: A case report.

Gunshot wounds in the maxillofacial region may cause serious defects that result in functional and esthetic disabilities. A 14-year-old male patient was referred to the prosthodontics clinic for provisional prosthetic restoration 5 months after an injury involving the midline midfacial region. An interim extraoral silicone maxillofacial prosthesis (MFP), also known as an epithesis, replacing the nose and upper lip, was fabricated to enhance appearance and speech intelligibility. The effect of the prosthesis insertion on speech outcome was assessed over 6 months. Blood pulse oxygen saturation levels and heart rate were monitored to assess ventilation following the prosthesis insertion. Results of the Assessment of Articulation Subtest revealed the patient produced the target speech sounds of 31 more words correctly at 6 months follow-up. Bilabial, labiodental, and postalveolar speech sounds in the phonetic inventory improved. Fabrication of an extraoral silicone MFP, modifying substructure design, and prosthesis usage over time contributed to the significant enhancement of speech intelligibility and did not significantly change the blood pulse oxygen saturation levels and heart rate. It led to an improvement in overall aesthetic outcomes and was a useful tool for the patient's social integration.

Gunshot Abdominal Injuries: A Report of Two Cases and a Review of the Literature.

Abdominal injuries in children caused by guns are a rare clinical entity globally. But, in countries with undefined legal regulations and in war zones, urban violence is a tremendous social problem among older children and adolescents. This manuscript provides details regarding two cases of severe gunshot injuries in young children. The injuries were very complicated and included damage to the parenchymatous and hollow organs and major blood vessels. The clinical presentation on admission was severe and dramatic, but the patients survived. However, one patient developed numerous complications that required repeated surgical interventions and long treatment. This article provides a detailed description of injuries and how to treat them. Patient care requires a multidisciplinary approach, and the initial decision on further treatment depends on the patient's hemodynamic stability.

TREATMENT OF COMBAT GUNSHOT SHRAPNEL TRAUMA OF LARGE DEFECTS OF THE SOFT TISSUES OF THE LOWER EXTREMITIES WITH PLASTIC SURGERY IN COMBINATION WITH VACUUM ASSISTED WOUND CLOSURE (VAC).

OBJECTIVE: The aim: To evaluate efficacy of the tissue defect closure techniques in combination with VAC in the treatment of battle casualities of the lower extremities. PATIENTS AND METHODS: Materials and methods: The results of wound healing until complete wound closure, of 62 patients with shrapnel defects of the lower extremities where assessed. RESULTS: Results: Treatment of patients with soft tissue defects of the lower extremities using rotational flaps on the vascular pedicle and VAC significantly reduces the incidence of infectious complications (18.75% in the main group vs. 30% in the control group (p<0.05)), reduces the intensity of pain according to the VAS scale during the first week of treatment in the main group to 5±0.5 versus 7±0.8 in the control group (p<0.05) and reduces the length of hospital stay by 7 days. CONCLUSION: Conclusions: The use of rotational flaps on the vascular pedicle and local tissue closure techniques in combination with VAC is an effective method of treating patients with combat gunshot wounds of the soft tissues of the lower extremities.

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).

OBJECTIVE: 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. PATIENTS AND METHODS: 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: 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. CONCLUSION: 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.

Gunshot-related lower extremity nerve injuries.

OBJECTIVE: The purpose of this study was to describe the frequency of nerve injury associated with lower extremity ballistic trauma, the associated skeletal and soft tissue injuries, and the rate of neurologic recovery. DESIGN AND SETTING: A retrospective review of an institutional trauma database was completed at a single level 1 trauma academic medical center. PATIENTS: This was an institutional review board approved retrospective cohort study of patients over 16 years of age presenting with ballistic-related traumatic injury to the lower extremities between May 2018 and May 2019. All patients identified with lower extremity ballistic trauma were included in this study. The rate of nerve palsy, associated skeletal injury, and operative fixation were recorded for each anatomic zone. Rates of associated concomitant vascular injury, fracture, and compartment syndrome were collected through a review of the electronic medical records. Chart review was performed to evaluate outcomes and nerve recovery. RESULTS: Twenty-one patients (21 extremities, 21/148, 14%) were diagnosed by attending physicians, fellowship-trained in orthopedic trauma, as having ballistic-related nerve injuries. Seventy-three percent of patients with a documented neurologic injury (11/15) demonstrated complete nerve recovery as measured by the MRC and sensory scale assessment at most recent follow-up, while the rest demonstrated no improvement in their neurologic deficits from presentation. The rate of associated vascular injury in patients with lower extremity nerve palsies was 38% (8/21). While the rate of vascular injury in the absence of neurologic injury was 3% (4/127). CONCLUSIONS: This series of lower extremity nerve injuries in a large sample of urban lower extremity ballistic trauma noted a high rate of concomitant nerve injuries. An associated diagnosis of a vascular injury appears to portend a higher risk of neurologic injury. Treating surgeons should have a high index of suspicion for associated vascular injury in patients presenting with a ballistic lower extremity nerve palsy.
