Abdominal trauma after terrorist bombing attacks exhibits a unique pattern of injury

Explosive injuries due to terror attacks: 10-year clinical outcomes in an emergency department in the Middle East

OBJECTIVES

This study aimed to evaluate the clinical characteristics, anatomical injury distribution, and mortality-related factors among patients presenting to an emergency department in the Middle East with explosive injuries resulting from terror attacks over a 10-year period.

METHODS

This retrospective cohort study included 271 patients with explosion-related injuries admitted to a tertiary trauma center between January 1, 2015, and January 1, 2025. Data were extracted from electronic medical records using relevant ICD-10 codes and verified via blinded chart review. Injury severity was assessed using ISS, RTS, and SI scores. Clinical, laboratory, and outcome variables were analyzed. ROC analysis was performed to evaluate the prognostic performance of trauma scores.

RESULTS

A total of 36 patients (13 %) died during hospitalization. Non-survivors had significantly lower GCS and RTS scores, and higher ISS scores (p < 0.001). ICU admission, intubation, transfusion, and amputation rates were significantly higher among the deceased. RTS showed the highest predictive accuracy for mortality (AUC: 0.979), followed by ISS (AUC: 0.910). Optimal cut-off values for predicting mortality were RTS ≤8.5 and ISS ≥34.5. Both scores demonstrated strong associations with in-hospital mortality (p < 0.001).

CONCLUSION

Explosive injuries due to terror attacks result in substantial morbidity and mortality, particularly in cases involving central anatomical regions and high trauma severity. ISS and RTS are valuable tools for early prognostic assessment. Prompt triage, surgical intervention, and critical care support are essential for improving outcomes in such complex trauma scenarios.

Blast Waves Cause Immune System Dysfunction and Transient Bone Marrow Failure in a Mouse Model

Explosive devices, either conventional or improvised, are common sources of injuries during combat, civil unrest, and terror attacks, resulting in trauma from exposure to blast. A blast wave (BW), a near-instantaneous rise in pressure followed by a negative pressure, propagates through the body in milliseconds and can affect physiology for days/months after exposure. Epidemiological data show that blast-related casualties result in significantly higher susceptibility to wound infections, suggesting long-lasting immune modulatory effects from blast exposure. The mechanisms involved in BW-induced immune changes are poorly understood. We evaluated the effects of BW on the immune system using an established murine model. Animals were exposed to BWs (using an Advanced Blast Simulator), followed by longitudinally sampling for 14 days. Blood, bone marrow, and spleen were analyzed for changes in the 1) complete blood count (CBC), and 2) composition of bone marrow cells (BMC) and splenocytes, and 3) concentrations of systemic cytokines/chemokines. Our data demonstrate that BW results in transient bone marrow failure and long-term changes in the frequency and profile of progenitor cell populations. Viability progressively decreased in hematopoietic stem cells and pluripotent progenitor cells. Significant decrease of CD4⁺ T cells in the spleen indicates reduced functionality of adaptive immune system. Dynamic changes in the concentrations of several cytokines and chemokines such as IL-1α and IL-17 occurred potentially contributing to dysregulation of immune response after trauma. This work lays the foundation for identifying the potential mechanisms behind BW’s immunosuppressive effects to inform the recognition of this compromised status is crucial for the development of therapeutic interventions for infections to reduce recovery time of wounded patients injured by explosive devices.

Temporal-spatial organ response after blast-induced experimental blunt abdominal trauma

Abdominal trauma (AT) is of major global importance, particularly with the increased potential for civil, terroristic, and military trauma. The injury pattern and systemic consequences of blunt abdominal injuries are highly variable and frequently underestimated or even missed, and the pathomechanisms remain still poorly understood. Therefore, we investigated the temporal-spatial organ and immune response after a standardized blast-induced blunt AT. Anesthetized mice were exposed to a single blast wave centered on the epigastrium. At 2, 6, or 24 h after trauma, abdominal organ damage was assessed macroscopically, microscopically, and biochemically. A higher degree of trauma severity, determined by a reduction of the distance between the epigastrium and blast inductor, was reflected by a reduced survival rate. The hemodynamic monitoring during the first 120 min after AT revealed a decline in the mean arterial pressure within the first 80 min, whereas the heart rate remained quite stable. AT induced a systemic damage and inflammatory response, evidenced by elevated HMGB-1 and IL-6 plasma levels. The macroscopic injury pattern of the abdominal organs (while complex) was consistent, with the following frequency: liver > pancreas > spleen > left kidney > intestine > right kidney > others > lungs and was reflected by microscopic liver and pancreas damages. Plasma levels of organ dysfunction markers increased during the first 6 h after AT and subsequently declined, indicating an early, temporal impairment of the function on a multi-organ level. The established highly reproducible murine blunt AT, with time- and trauma-severity-dependent organ injury patterns, systemic inflammatory response, and impairment of various organ functions, reflects characteristics of human AT. In the future, this model may help to study the complex immuno-pathophysiological consequences and innovative therapeutic approaches after blunt AT.

Suicide Bombing Terrorism

INTRODUCTION

While suicide bombings in the context of warfare have existed throughout history, there was an exponential rise in such attacks in the decade following the initiation of the War on Terror. The health care implications of such attacks are a growing concern across the emergency response sector, and this study is an epidemiological examination of all terrorism-related bombings sustained from 1970-2019, comparing the rates of fatal injuries (FI) and non-fatal injuries (NFI) between suicide bombing attacks (SBA) versus non-suicide bombing attacks (NSBA).

METHOD

Data collection was performed using a retrospective database search through the Global Terrorism Database (GTD). The GTD database was downloaded and searched using the internal database search functions for all events that occurred from January 1, 1970 - December 31, 2019. Bombing/explosion as a primary "attack type" and explosives as a primary "weapon type" were selected for the purpose of this study, and events were further sub-classified as either "suicide attack" or "non-suicide attack." Results were exported into an Excel spreadsheet (Microsoft Corp.; Redmond, Washington USA) for analysis.

FINDINGS

There were 82,217 bombing/explosion terrorist attacks using explosives documented during the study period with 135,807 fatalities and 352,500 NFI.A total of 5,416 events (6.59% of all events) were sub-classified as SBA causing 52,317 FI (38.52% of all FI) and 107,062 NFI (30.37% of all NFI).Mean SBA FI was 9.66 per event and mean SBA NFI was 19.77 per event compared to a mean NSBA FI of 1.09 per event and mean NSBA NFI of 3.20 per event.

CONCLUSION

Suicide bombing attacks are a unique terrorist methodology that can inflict wide-spread psychological damage as well as significantly higher death and injury tolls when compared to more traditional NSBA. They have been increasing in popularity amongst terrorist organizations and groups, and Counter-Terrorism Medicine (CTM) specialists need to be aware of the unique injury patterns and potential risk mitigation strategies associated with SBA depending on the target type, location, and gender of the perpetrator.

Imaging findings in patients after the bomb explosion in Somalia on December 28, 2019

INTRODUCTION

This study aimed to present the radiological findings of injuries in victims as a result of a suicide bombing in Mogadishu, Somalia.

METHODS

Of the 82 injured cases admitted to the emergency department within the first six hours after the explosion, those who were radiologically evaluated were included in this retrospective and descriptive study. To analyze and identify the distribution of primary, secondary, and tertiary injuries, they were classified according to the body areas as head-neck, thorax, abdominopelvic, extremity, and vertebra.

RESULTS

The mean age (mean ± SD) of 63 patients included in the study was 28.6 ± 10.2 years. Twenty-four (38.1%) of the injured patients were female and 39 (61.9%) were male. Secondary blast injury was the most common type of injury in the study group with a rate of 39/63 (62%). The total number of bomb fragments was 235, of which 113 (47.8%) were seen in the head and neck region, followed by 86 (36.5%) in the extremities. There were 10 patients (15.9%) with lung injury and 13 (20.6%) with tympanic membrane perforation due to the primary blast mechanism.

CONCLUSION

Radiological imaging plays an important role in identifying specific findings and patterns of explosive injuries. Therefore, we consider that patients with stable hemodynamics should be radiologically examined for a fast and accurate diagnosis or treatment.

Laparotomy Due to War-Related Penetrating Abdominal Trauma in Civilians: Experience From Syria 2011-2017

OBJECTIVES

Penetrating abdominal trauma is one of the injuries that could affect civilians in wartime. This retrospective study investigates the commonly injured abdominal organs, and the impact of multiple injured organs on mortality.

METHODS

We reviewed the operating room (OR) logs of patients who presented to the surgical emergency department (SED) at Al-Mouwasat University Hospital with war-related abdominal penetrating trauma requiring exploratory laparotomy between April 1, 2011 and December 31, 2017.

RESULTS

Of 7826 patients with traumatic injuries, 898 patients (11.5%) required exploratory laparotomy. Of all patients who had an exploratory laparotomy (n = 898), 58 patients (6.5%) died in the perioperative period. Regarding complete laparotomies (n = 873 patients), small intestines, large intestines, and liver were the most commonly affected organs (36.4%, 33%, 22.9%, respectively). A total of 92 patients (10.2%) had negative laparotomy in which all the abdominal organs were not injured. The perioperative mortality rate (POMR) increased when more organs/organ systems were injured per patient reaching a peak at 3 organs/organ systems injuries with a POMR of 8.3%. POMR was highest in patients with musculoskeletal injuries (18.2%), followed by vascular injuries (11.8%), and liver injuries (7%).

CONCLUSIONS

The management of civilians' abdominal injuries remains a challenge for general and trauma surgeons, especially the civilian trauma team. The number and type of injured organs and their correlation with mortality should be considered during surgical management of penetrating abdominal injuries.

Injury patterns and causes of death in 953 patients with penetrating abdominal war wounds in a civilian independent non-governmental organization hospital in Lashkargah, Afghanistan

BACKGROUND

Management of penetrating abdominal war injuries centers upon triage, echeloned care, and damage control. A civilian hospital based in a war zone can rarely rely upon these principles because it normally has limited resources and lacks rapid medical evacuation. We designed this study to describe organ injury patterns and factors related to mortality in patients with penetrating abdominal war injuries in a civilian hospital in an active war zone in Afghanistan, examine how these findings differ from those in a typical military setting, and evaluate how they might improve patients' care.

METHODS

We reviewed the records of all patients admitted at the Lashkargah "Emergency" hospital with penetrating abdominal injuries treated from January 2006 to December 2016. Demographic and clinical data were recorded; univariate and multivariate analyses were used to identify variables significantly associated with death.

RESULTS

We treated 953 patients for penetrating abdominal injury. The population was mainly civilian (12.1% women and 21% under 14). Mean age was 23 years, and patients with blast injuries were younger than in the other groups. The mechanism of injury was bullet injury in 589 patients, shell injury in 246, stab wound in 97, and mine injury in 21. The most frequent abdominal lesion was small bowel injury (46.3%). Small and large bowel injuries were the most frequent in the blast groups, stomach injury in stab wounds. Overall mortality was 12.8%. Variables significantly associated with death were age > 34 years, mine and bullet injury, length of stay, time since injury > 5 h, injury severity score > 17, and associated injuries.

CONCLUSIONS

Epidemiology and patterns of injury in a civilian hospital differ from those reported in a typical military setting. Our population is mainly civilian with a significant number of women and patients under 14 years. BI are more frequent than blast injuries, and gastrointestinal injuries are more common than injuries to solid organs. In this austere setting, surgeons need to acquire a wide range of skills from multiple surgical specialties. These findings might guide trauma and general surgeons treating penetrating abdominal war wounds to achieve better care and outcome.

Anthropogenic Disasters

Anthropogenic disasters may be defined as any disaster caused by human action or inaction. Natural disasters occur without human interference. Injuries caused by terrorists and related criminal activities may be broadly grouped into 3 categories: blunt, blast, and penetrating trauma. Most terrorist and criminal activities that create a mass-casualty situation are performed using the weapons most readily available, such as firearms or explosives. A consistent pattern, comparing terrorism with interpersonal violence, is the greater severity of impact on the victim.

[Management of traumatic intestinal injury of mass casualties]

While intestinal injury is relatively rare in blunt abdominal trauma, it is common in penetrating abdominal trauma. Intestinal injury cannot be detected effectively by computed tomography (CT); therefore penetrating abdominal injury or abdominal signs in blunt trauma require liberal indications for explorative laparotomy. In mass casualty situations patients with hemodynamic instability and abdominal signs should be prioritized for surgery. Besides intra-abdominal hemorrhage the major issue is septic complications due to intestinal perforation. The current surgical strategy should reflect the number of injured patients and the individual pattern of injuries. Damage control surgery is not an effective strategy to improve survival rates in severely injured patients or in mass casualty situations. Damage control surgery focuses on lifesaving procedures especially bleeding control and control of contamination. This includes an open abdomen strategy with later definitive repair and abdominal wall closure.

Terrorist Stabbings-Distinctive Characteristics and How to Prepare for Them

BACKGROUND

The number of terror attack incidents is on the increase worldwide. The knife is one of the weapons most commonly used among terrorists. Appropriate preparation in trauma units for coping with the increasing numbers of terrorist-inflicted stabbings is different from the preparation suitable for civilian stabbings. Therapeutic and logistic guidelines need to be adjusted to accommodate those differences.

OBJECTIVES

Characterize the unique injuries related to terrorist stabbing, and suggest preparedness actions.

METHODS

Retrospective data on all terrorist-inflicted stabbing incidents between September 2015 and May 2016 were retrieved from the database of the national Israeli emergency medical services and from the Israeli Defense Forces Medical Corps records.

RESULTS

There were a total of 414 civilian victims (34 fatalities) of terror incidents. Of these, 161 involved stabbings during 106 separate incidents. There was more than 1 stab wound per patient in approximately 60% of cases, and more than 1 victim in approximately 40% of cases. Unlike civilian stabbings, terrorist stabbings were characterized by more commonly occurring to the upper part of the body, being executed by large knives with high force, and involving multiple and more severe injuries.

CONCLUSION

There is a clear distinction between the characteristics of wounds resulting from civilian stabbings and those incurred by acts of terror. Terrorists intend to injure as many random victims as possible, and trauma units need to be prepared to cope with the simultaneous admission of multiple patients with penetrating and often life-threatening knife wounds.

Penetrating abdominal injuries during the Syrian war: Patterns and factors affecting mortality rates

BACKGROUND

A large number of innocent Syrians were injured or killed during the years of war. This retrospective study investigates the differences in patterns of injury and factors affecting the mortality rate in 324 patients coming to Damascus Hospital with penetrating abdominal trauma, and illustrates the difficulties of diagnosis and decision making in crisis situations.

METHODS

A retrospective study was registered from patient's records between October 2012 and June 2013 in Damascus Hospital. All victims were injured either by explosions or gunshots.

RESULTS

A total of 325 patients: 183 by explosion; 56.3%, 141 by gunshot; 43.3%, and one patient by other means; 0.3% were reviewed. The study focused on the two large groups with a total of 324 patients. Males were predominant (82.1%; n=266) and the majority of patients were between 19 and 35 years old. Patients suffering from multi abdominal organ injury were more common in gunshot group (n=72, 51.1%) compared to the explosion group (n=83, 45.3%). 264 patients (81.5%) underwent surgical operations and only 22 (8.3%) had normal laparotomy. The inpatient mortality rate was (17.0%; n=55), and there was no difference in mortality rate between the two groups. More than the half of deaths (n=42; 76.4%) had a P.A.T.I score≥25 where the death rate was 35.6% which is higher compared to 6.3% in those with a P.A.T.I<25. In the ICU 33 patients died, of these (87.9%; n=29) died after immediate admission to the ICU which is higher compared with a later admission (12.1%; n=4). The need for massive blood transfusion affected the mortality rate.

CONCLUSION

Efforts must be directed toward training of medical staff to deal with crisis incidents. The need for massive blood transfusion and ICU admissions can affects mortality. P.A.T.I was found to be an effective predictor of mortality. Clinical experience in this field can produce better health care and faster judgments.

When a vehicle becomes a weapon: intentional vehicular assaults in Israel

Background

We have recently witnessed an epidemic of intentional vehicular assaults (IVA) aimed at pedestrians. We hypothesized that IVA are associated with a specific injury pattern and severity.

Methods

Retrospective analysis of prospectively acquired data of patients injured following IVA from October 2008 to May 2016 who were admitted to the Hadassah Level I trauma center in Jerusalem, Israel. Comparison of injury parameters and outcome caused by vehicular attacks to non-intentional pedestrian trauma (PT). Measured outcomes included ISS, AIS, injury pattern, ICU and blood requirements, participating teams, length of stay, and mortality.

Results

There were 26 patients in the IVA group. Mean age in the IVA group was significantly younger and there were more males compared to the PT group (24.7 ± 13.3 years vs. 48.3 ± 21.3, and 81% vs. 52%, respectively, p < 0.01). Lower extremity (77% of patients), followed by head (58%) and facial (54%) injuries were most commonly injured in the IVA group, and this was significantly different from the pattern of injury in the PT group (54, 35, and 28%, respectively, p < 0.05). Mean ISS and median head AIS were significantly higher in the IVA group compared with the PT group (23.2 ± 12.8 vs. 15.4 ± 13.8, p = 0.012, and 4.5 vs. 3, p = 0.003, respectively). ICU admission and blood requirement were significantly higher in the IVA group (69% vs. 38%, and 50% vs. 19%, p < 0.01). Mortality was significantly higher in the IVA group (4 patients, 15%, vs. 3 patients, 4%, respectively, p = 0.036) and was caused by severe head trauma in all cases.

Discussion

The severity of injury and mortality rate following IVA are higher compared with pedestrian injury. The pattern of injury following IVA is significantly different from non-intentional pedestrian trauma.

Conclusions

IVA results in higher mortality than conventional pedestrian trauma secondary to more severe head injury. More hospital resources are required following IVA than following conventional road traffic accidents.

Imaging features of blast injuries: experience from 2015 Ankara bombing in Turkey

OBJECTIVE

To present the radiological features of blast-related injuries in the victims of the 10 October 2015 Ankara bombing and emphasize the importance of imaging.

METHODS

This retrospective descriptive study included a total of 28 patients who underwent CT scan or radiographic imaging within 6 h after the bombing on 10 October 2015. CT scans and plain radiographs were evaluated regarding mechanisms of injuries. Injuries were categorized as primary, secondary, tertiary and quaternary. The number of shrapnel and distribution of injuries were noted. Injury Severity Score (ISS) was used to rank the severity of the injury.

RESULTS

Primary blast injuries consisted of only tympanic membrane rupture. A high rate of patients (21/28 patients) in the study group suffered from secondary blast injuries. Tertiary injuries were detected in only three patients. Of the severely injured patients, five had abdominal injuries, three had thoracic injuries and six had extremity injuries. ISS was significantly higher in patients with thoracic and abdominal injuries.

CONCLUSION

Our results after the suicide bomb attacks showed that the most common injury pattern was secondary blast injury. The torso was the most commonly injured body region, followed by the extremities. This specific injury pattern requires the use of immense radiological imaging. Hence, radiologists should be aware of the mechanisms and spectrums of blast-related injuries.

ADVANCES IN KNOWLEDGE

Both the unique injury pattern and the following chaos make blast-related injuries a challenge in terms of triage, diagnosis and management. Radiologists should be familiar with the wide spectrum of these unique injuries.

Abdominal injuries in communal crises: The Jos experience

Background:

Abdominal injuries contribute significantly to battlefield trauma morbidity and mortality. This study sought to determine the incidence, demographics, clinical features, spectrum, severity, management, and outcome of abdominal trauma during a civilian conflict.

Materials and Methods:

A prospective analysis of patients treated for abdominal trauma during the Jos civil crises between December 2010 and May 2012 at the Jos University Teaching Hospital.

Results:

A total of 109 victims of communal conflicts with abdominal injuries were managed during the study period with 89 (81.7%) males and 20 (18.3%) females representing about 12.2% of the total 897 combat related injuries. The peak age incidence was between 21 and 40 years (range: 3–71 years). The most frequently injured intra-abdominal organs were the small intestine 69 (63.3%), colon 48 (44%), and liver 41 (37.6%). Forty-four (40.4%) patients had extra-abdominal injuries involving the chest in 17 (15.6%), musculoskeletal 12 (11%), and the head in 9 (8.3%). The most prevalent weapon injuries were gunshot 76 (69.7%), explosives 12 (11%), stab injuries 11 (10.1%), and blunt abdominal trauma 10 (9.2%). The injury severity score varied from 8 to 52 (mean: 20.8) with a fatality rate of 11 (10.1%) and morbidity rate of 29 (26.6%). Presence of irreversible shock, 3 or more injured intra-abdominal organs, severe head injuries, and delayed presentation were the main factors associated with mortality.

Conclusion:

Abdominal trauma is major life-threatening injuries during conflicts. Substantial mortality occurred with loss of nearly one in every 10 hospitalized victims despite aggressive emergency room resuscitation. The resources expenditure, propensity for death and expediency of timing reinforce the need for early access to the wounded in a concerted trauma care systems.

Pelvic Trauma

The leading cause of death in the pediatric population is trauma, of which pelvic injuries make up a very small percentage. Trauma to the pelvis can result in multiple injuries to the bony pelvis, rectum, bladder, and or the urethra. Although mortality in the pediatric population is typically secondary to associated injuries, pelvic hemorrhage can be a life-threatening event. The management of patients with complex pelvic injuries requires a multidisciplinary approach in order to achieve the best possible outcomes.

Lower genitourinary trauma in modern warfare: the experience from civil violence in Iraq

BACKGROUND

Reports on genitourinary (GU) trauma during the Iraqi conflict have been limited to battlefield injuries. We sought to characterise the incidence, mechanism of injury, wounding pattern, and management of lower GU injuries sustained in civil violence during the Iraqi war.

PATIENTS AND METHODS

A total of 2800 casualties with penetrating trauma to the abdomen and pelvis were treated at the Yarmouk Hospital, Baghdad from January 2004 to June 2008. Of the casualties 504 (18%) had GU trauma including 217 (43%) with one or more injuries to the lower GU organs.

RESULTS

Among the 217 patients there were 262 lower GU injuries involving the bladder in 128 (48.8%) patients, bulbo-prostatic urethra in 21 (8%), penis in 24 (9.2%), and scrotum in 89 (34%). Injuries to the anterior urethra and genitals were inflicted by Improvised Explosive Devices (IEDs) in 53-67% of cases and by individual firearms in 33-47%, while injuries to the posterior urethra and bladder were inflicted by IEDs in 17-22% of cases and by firearms in 78-83%. All penile wounds were repaired save 3 (12.5%) patients who underwent total penectomy. Of 63 injured testicles 54 (86%) could be salvaged and 9 (14%) required unilateral orchiectomy. The leading cause of death was an associated injury to major blood vessels in 26 (84%) of 31 patients who died.

CONCLUSIONS

Injuries to the anterior urethra and genitals were commonly caused by IEDs, while injuries to the posterior urethra and bladder were usually caused by individual firearms. Testis injury was almost always salvageable. Associated trauma to major blood vessels was the leading cause of death in these casualties.

Abdominal blast injuries: different patterns, severity, management, and prognosis according to the main mechanism of injury

PURPOSE

To review the frequency, different patterns, anatomic severity, management, and prognosis of abdominal injuries in survivors of explosions, according to the main mechanism of injury.

METHODS

A MEDLINE search was conducted from January 1982 to August 2013, including the following MeSH terms: blast injuries, abdominal injuries. EMBASE was also searched, with the same entries. Abdominal blast injuries (ABIs) have been defined as injuries resulting not only from the effects of the overpressure on abdominal organs, but also from the multimechanistic effects and projectile fragments resulting from the blast. Special emphasis was placed on the detailed assessment of ABIs in patients admitted to GMUGH (Gregorio Marañón University General Hospital) after the Madrid 2004 terrorist bombings, and in patients admitted to HYMC (Hillel Yaffe Medical Centre) in Hadera (Israel) following several bombing episodes. The anatomic severity of injuries was assessed by the abdominal component of the AIS, and the overall anatomic severity of casualties was assessed by means of the NISS.

RESULTS

Abdominal injuries are not common in survivors of terrorist explosions, although they are a frequent finding in those immediately killed. Primary and tertiary blast injuries have predominated in survivors from explosions in enclosed spaces reported outside of Israel. In contrast, secondary blast injuries causing fragmentation wounds were predominant in suicide bombings in open and/or semi-confined spaces, mainly in Israel, and also in military conflicts. Multiple perforations of the ileum seem to be the most common primary blast injury to the bowel, but delayed bowel perforations are rare. Secondary blast injuries carry the highest anatomic severity and mortality rate. Most of the deaths assessed occurred early, with hemorrhagic shock from penetrating fragments as the main contributing factor. The negative laparotomy rate has been very variable, with higher rates reported, in general, from civilian hospitals attending a large number of casualties.

CONCLUSIONS

The pattern, severity, management, and prognosis of ABI vary considerably, in accordance with the main mechanism of injury.

Urethral and penile war injuries: The experience from civil violence in Iraq

Objective

To determine the incidence, mechanism of injury, wounding pattern and surgical management of urethral and penile injuries sustained in civil violence during the Iraq war.

Patients and methods

In all, 2800 casualties with penetrating trauma to the abdomen and pelvis were received at the Al-Yarmouk Hospital, Baghdad, from January 2004 to June 2008. Of these casualties 504 (18%) had genitourinary trauma, including 45 (8.9%) with urethral and/or penile injuries.

Results

Of 45 patients, 29 (64%) were civilians and 16 (36%) were Iraqi military personnel. The injury was caused by an improvised explosive device (IED) in 25 (56%) patients and by individual firearms in 20 (44%). Of the patients, 24 had penile injuries, 15 had an injury to the bulbar urethra and six had an injury to the posterior urethra. Anterior urethral injuries were managed by primary repair, while posterior urethral injuries were managed by primary realignment in five patients and by a suprapubic cystostomy alone in one. An associated injury to major blood vessels was the cause of death in eight of nine patients who died soon after surgery (P < 0.001).

Conclusion

Urethral and penile injuries were caused by IEDs and individual firearms with a similar frequency. Most of the casualties were civilians and a minority were military personnel. Injuries to the anterior urethra can be managed by primary repair, while injuries to the posterior urethra can be managed by primary realignment. An associated trauma to major blood vessels was the leading cause of death in these casualties.

A modern combat trauma

INTRODUCTION

The world remains plagued by wars and terrorist attacks, and improvised explosive devices (IED) are the main weapons of our current enemies, causing almost two-thirds of all combat injuries. We wished to analyse the pattern of blast trauma on the modern battlefield and to compare it with combat gunshot injuries.

MATERIALS AND METHODS

Analysis of a consecutive series of combat trauma patients presenting to two Bulgarian combat surgical teams in Afghanistan over 11 months. Demographics, injury patterns and Injury Severity Scores (ISS) were compared between blast and gunshot-injured casualties using Fisher's Exact Test.

RESULTS

The blast victims had significantly higher median ISS (20.54 vs 9.23) and higher proportion of ISS>16 (60% vs 33.92%, p=0.008) than gunshot cases. They also had more frequent involvement of three or more body regions (47.22% vs 3.58%, p<0.0001). A significantly higher frequency of head (27.27% vs 3.57%), facial (20% vs 0%) and extremities injuries (85.45% vs 42.86%) and burns (12.72% vs 0%) was noted among the victims of explosion (p<0.0001). Based on clinical examination and diagnostic imaging, primary blast injury was identified in 24/55 (43.6%), secondary blast injury in 37 blast cases (67.3%), tertiary in 15 (27.3%) and quaternary blast injury (all burns) in seven (12.72%).

CONCLUSIONS

Our results corroborate the 'multidimensional' injury pattern of blast trauma. The complexity of the blast trauma demands a good knowledge and a special training of the military surgeons and hospital personnel before deployment.

Trauma care and case fatality during a period of frequent, violent terror attacks and thereafter

BACKGROUND

From September 1999 through January 2004 during the second Intifada (al-Aqsa), there were frequent terror attacks in Jerusalem. We assessed the effects on case fatality of introducing a specialized, intensified approach to trauma care at the Hebrew University-Hadassah Hospital Shock Trauma Unit (HHSTU) and other level I Israeli trauma units. This approach included close senior supervision of prehospital triage, transport, and all surgical procedures and longer hospital stays despite high patient-staff ratios and low hospital budgets. Care for lower income patients also was subsidized.

METHODS

We tracked case fatality rates (CFRs) initially during a period of terror attacks (1999-2003) in 8,127 patients (190 deaths) at HHSTU in subgroups categorized by age, injury circumstances, and injury severity scores (ISSs). Our comparisons were four other Israeli level I trauma centers (n = 2,000 patients), and 51 level I U.S. trauma centers (n = 265,902 patients; 15,237 deaths). Detailed HHSTU follow-up continued to 2010.

RESULTS

Five-year HHSTU CFR (2.62 %) was less than half that in 51 U.S. centers (5.73 %). CFR progressively decreased; in contrast to a rising trend in the US for all age groups, injury types, and ISS groupings, including gunshot wounds (GSW). Patients with ISS > 25 accounted for 170 (89 %) of the 190 deaths in HHSTU. Forty-one lives were saved notionally based on U.S. CFRs within this group. However, far more lives were saved from reductions in low CFRs in large numbers of patients with ISS < 25. CFRs in HHSTU and other Israeli trauma units decreased more through the decade to 1.9 % up to 2010.

CONCLUSIONS

Sustained reductions in trauma unit CFRs followed introduction of a specialized, intensified approach to trauma care.

Indicators of the need for ICU admission following suicide bombing attacks

INTRODUCTION

Critical hospital resources, especially the demand for ICU beds, are usually limited following mass casualty incidents such as suicide bombing attacks (SBA). Our primary objective was to identify easily diagnosed external signs of injury that will serve as indicators of the need for ICU admission. Our secondary objective was to analyze under- and over-triage following suicidal bombing attacks.

METHODS

A database was collected prospectively from patients who were admitted to Hadassah University Hospital Level I Trauma Centre, Jerusalem, Israel from August 2001-August 2005 following a SBA. One hundred and sixty four victims of 17 suicide bombing attacks were divided into two groups according to ICU and non-ICU admission.

RESULTS

There were 86 patients in the ICU group (52.4%) and 78 patients in the non-ICU group (47.6%). Patients in the ICU group required significantly more operating room time compared with patients in the non-ICU group (59.3% vs. 25.6%, respectively, p=0.0003). For the ICU group, median ICU stay was 4 days (IQR 2 to 8.25 days). On multivariable analysis only the presence of facial fractures (p=0.014), peripheral vascular injury (p=0.015), injury≥4 body areas (p=0.002) and skull fractures (p=0.017) were found to be independent predictors of the need for ICU admission. Sixteen survivors (19.5%) in the ICU group were admitted to the ICU for one day only (ICU-LOS=1) and were defined as over-triaged. Median ISS for this group was significantly lower compared with patients who were admitted to the ICU for >1 day (ICU-LOS>1). This group of over-triaged patients could not be distinguished from the other ICU patients based on external signs of trauma. None of the patients in the non-ICU group were subsequently transferred to the ICU.

CONCLUSIONS

Our results show that following SBA, injury to ≥4 areas, and certain types of injuries such as facial and skull fractures, and peripheral vascular injury, can serve as surrogates of severe trauma and the need for ICU admission. Over-triage rates following SBA can be limited by a concerted, focused plan implemented by dedicated personnel and by the liberal utilization of imaging studies.

Abdominal trauma in primary blast injury

BACKGROUND

Blast injury is uncommon, and remains poorly understood by most clinicians outside regions of active warfare. Primary blast injury (PBI) results from the interaction of the blast wave with the body, and typically affects gas-containing organs such as the ear, lungs and gastrointestinal tract. This review investigates the mechanisms and injuries sustained to the abdomen following blast exposure.

METHODS

MEDLINE was searched using the keywords 'primary blast injury', 'abdominal blast' and 'abdominal blast injury' to identify English language reports of abdominal PBI. Clinical reports providing sufficient data were used to calculate the incidence of abdominal PBI in hospitalized survivors of air blast, and in open- and enclosed-space detonations.

RESULTS

Sixty-one articles were identified that primarily reported clinical or experimental abdominal PBI. Nine clinical reports provided sufficient data to calculate an incidence of abdominal PBI; 31 (3·0 per cent) of 1040 hospitalized survivors of air blast suffered abdominal PBI, the incidence ranging from 1·3 to 33 per cent. The incidence for open- and enclosed-space detonations was 5·6 and 6·7 per cent respectively. The terminal ileum and caecum were the most commonly affected organs. Surgical management of abdominal PBI is similar to that of abdominal trauma of other causes.

CONCLUSION

Abdominal PBI is uncommon but has the potential for significant mortality and morbidity, which may present many days after blast exposure. It is commoner after blast in enclosed spaces and under water.

Prehospital care algorithm for blast injuries due to bombing incidents

Terrorist bombings continue to remain a risk for local jurisdictions, and retrospective data from the United States show that bombings occur in residential and business areas due to interpersonal violence without political motives. In the event of a mass-casualty bombing incident, prehospital care providers will have the responsibility for identifying and managing blast injuries unique to bombing victims. In a large-scale event, emergency medical services personnel should be required to provide prolonged medical care in the prehospital setting, and they will be able to deliver improved care with a better understanding of blast injuries and a concise algorithm for managing them. Blast injuries are categorized as primary, secondary, tertiary, and quaternary, and these injuries are related to the mechanism of injury from the blast event. After an initial evaluation, the emergency healthcare provider should consider following a universal algorithm to identify and treat blast injuries within these categories to prevent further morbidity or mortality in the prehospital setting.

The pattern of thoracic trauma after suicide terrorist bombing attacks

BACKGROUND

The worldwide escalation in the volume of suicide terrorist bombing attacks warrants special attention to the specific pattern of injury associated with such attacks. The goal of this study was to characterize thoracic injuries inflicted by terrorist-related explosions and compare pattern of injury to penetrating and blunt thoracic trauma.

METHODS

Prospectively collected database of patients with chest injury who were admitted to Hadassah Hospital Level I trauma centre, in Jerusalem, Israel, from October 2000 to December 2005. Patients were divided into three groups according to the mechanism of injury: terrorist explosions (n = 55), gunshot wounds (GSW; n = 78), and blunt trauma (n = 747).

RESULTS

There were many female victims after suicide bombing attacks (49.1%) compared with GSW (21.8%) and blunt trauma (24.6%; p = 0.009). The number of body regions injured was significantly higher in the terror group compared with the GSW and blunt groups (median, 4, 2, and 3, respectively, p < 0.0001). The pattern of chest injury after suicide bombing attacks was caused by a unique combination of the effects of the blast wave and penetrating shrapnel. More than half (52.7%) of the terror victims suffered from lung contusion and 25 (45.5%) required tube thoracostomy. Five patients (9.1%) underwent thoracotomy for lung lacerations (n = 3), injury to great vessels (n = 2), cardiac lacerations (n = 1), and esophageal injury (n = 1). Penetrating shrapnel was the mechanism of injury in all these cases.

CONCLUSIONS

Injury inflicted by terrorist bombings causes a unique pattern of thoracic wounds. Victims are exposed to a combination of lung injury caused by the blast wave and penetrating injury caused by metallic objects.
