Nonintracranial fatal firearm injuries in children: implications for treatment

BACKGROUND: Understanding the injury characteristics of nonintracranial fatal (NIF) gunshot wounds in children treated in a statewide trauma system will help guide effective treatment strategies. METHODS: This study was a retrospective analysis of children fatally injured with firearms. The review included demographic information, firearm injury characteristics, and outcome. The setting included trauma centers participating in a statewide trauma registry. Patients were all children (age < 18 years) treated in trauma centers for NIF gunshot wounds from January 1988 through December 2000. The main outcome measures were characteristics of fatal firearm injuries in children. RESULTS: Over the 13-year period, there were 1,954 children with firearm injuries including 368 (18.8%) children with fatal wounds. Of the fatally wounded children, 177 (48.1%) had no intracranial injury. The NIF injury population was 90.4% male, with a mean age of 14.9 years (range, <1-17 years) and an Injury Severity Score of 38.2 (range, 9-75). Over 95% of deaths in this group occurred within 24 hours of admission. Although injuries to the thorax were most common (78.5%), 48.6% of the NIF cohort had injuries to multiple body regions, including 31% with injuries in both the abdomen and thorax. Compared with all children wounded by firearms, NIF firearm injury patients had, on average, more body regions injured (1.6 vs. 1.1, p < 0.001) and a greater total number of injuries (6.0 vs. 3.5, p < 0.001). Patients with an NIF injury were more likely to suffer a major vascular injury (54.8% vs. 13.8%, p < 0.001), lung injury (56.5% vs. 12.9%, p < 0.001), or cardiac injury (44.6% vs. 4.6%, p < 0.001) than all children with a firearm injury. CONCLUSION: Most children who arrive at trauma centers alive and subsequently die from NIF firearm injuries do so rapidly from major vascular and thoracic injury. Almost half of these children have injuries to multiple body regions, further complicating management. Innovative, aggressive treatment approaches should be sought to improve survival in this extremely injured cohort of children.     

Abdominal wound injuries: diagnosis and treatment. Report of 79 cases

INTRODUCTION. - Traditionally, penetrating abdominal wounds justify routine laparotomy. However, this policy can be adapted to mechanism of injury (stab or firearm) and accuracy of imaging procedures if they eliminate visceral injury thus allowing close follow up. PATIENTS AND METHODS: Retrospective study of 79 patients (May 1995-May 2002) with a penetrating abdominal wound: (47 (59%) stab wounds and 32 (41 %) firearm wounds). Correlation between imaging and surgical findings, treatment, post-operative course were studied. RESULTS: Sixty-eight patients were operated on from the outset, and 11 underwent close follow-up. Of the 11 patients who had follow-up, (9 after stab wound and 2 after firearm wound), two had to be operated (1 in each group). Correlation between imaging and surgical findings was good in 34 (72%) patients after stab wound and in 21 (80%) after firearm wound; the mean number of visceral injuries was 1 and 3 respectively. Six patients (8%) died (mortality: 2% and 16% respectively), 12 (15%) had postoperative complications. CONCLUSION: Penetrating abdominal stab wounds can be treated by close follow-up if imaging excludes visceral injury. Firearm wounds still justify routine laparotomy due to both multiplicity of visceral injuries and bad prognosis.     

Occult injuries to the diaphragm: prospective evaluation of laparoscopy in penetrating injuries to the left lower chest

Background: To evaluate the incidence of occult diaphragmatic injuries and investigate the role of laparoscopy in patients with penetrating trauma to the left lower chest who lack indications for exploratory celiotomy other than the potential for a diaphragm injury.

Study Design: Patients with penetrating injuries to the left lower chest who were hemodynamically stable and without indications for a celiotomy were prospectively evaluated with diagnostic laparoscopy to determine the presence of an injury to the left hemidiaphragm. Diagnostic laparoscopy was performed in the operating room under general anesthesia.

Results: One-hundred-ten patients (94 stab wounds, 16 gunshot wounds) were evaluated with laparoscopy. Twenty-six (24%) diaphragmatic injuries were identified (26% for stab wounds and 13% for gunshot wounds). Comparison of patients with diaphragmatic injuries with those without diaphragmatic injuries demonstrated a slightly greater incidence of hemo/pneumothoraces (35% versus 24%, NS). The incidence of diaphragmatic injuries in patients with a normal chest x-ray was 21% versus 31% for patients with a hemo/pneumothorax. An elevated left hemidiaphragm was associated with a diaphragmatic injuries in only 1 of 7 patients (14%). The incidence of diaphragmatic injuries was similar for anterior, lateral, and posterior injuries (22%, 27%, and 22% respectively).

Conclusions: The incidence of occult diaphragmatic injuries in penetrating trauma to the left lower chest is high, 24%. These injuries are associated with a lack of clinical and radiographic findings, and would have been missed had laparoscopy not been performed. Patients with penetrating trauma to the left lower chest who do not have any other indication for a celiotomy should undergo videoscopic evaluation of the left hemidiaphragm to exclude an occult injury.     

Occult diaphragmatic injuries caused by stab wounds

BACKGROUND: Missed diaphragmatic perforation caused by penetrating trauma can lead to subsequent strangulation of a hollow viscus, which has prompted the use of invasive diagnostic procedures to exclude occult diaphragmatic injuries in asymptomatic, high-risk patients. The objective of this study was to determine the incidence of occult diaphragmatic injuries caused by stab wounds of the lower chest and upper abdomen, and to examine the natural history and consequences of missed diaphragmatic injuries. METHODS: On the basis of patient data from two previous randomized studies from our institution, a retrospective analysis was performed on 97 patients treated for anterior stab wounds located between the nipple line, the umbilical level, and the posterior axillary lines not having indications for immediate surgical exploration. The patients were divided into two groups on the basis of their initial randomized management (open or laparoscopic exploration vs. expectant observation). RESULTS: In the exploration group (n = 47), four diaphragmatic injuries (9%) were detected (three left-sided and one right-sided). Excluding patients with associated injuries requiring surgical repair, the incidence of occult diaphragmatic injuries was 3 of 43 (7%). In the observation group (n = 50), there were two patients (4%) with delayed presentation of missed left-sided diaphragmatic injury 2 and 23 months later, respectively. Both injuries resulted from stab wounds of the left flank and presented with herniation of the stomach or small bowel and colon. The overall incidence of occult diaphragmatic injuries in left-sided thoracoabdominal stab wounds was 4 of 24 (17%), and was much lower after stab wounds of left epigastrium (0%), right lower chest (0%), and right epigastrium (4%). CONCLUSION: In asymptomatic patients with anterior or flank stab wounds of the lower chest or upper abdominal area, the risk of an occult diaphragmatic injury is approximately 7% which, if undetected, is associated with a high risk of subsequent hollow viscus herniation. Exclusion of an occult diaphragmatic injury with invasive diagnostic methods, such as laparoscopy or thoracoscopy, should be considered at least in left-sided stab wounds of the lower chest.     

Does Body Armor Protect from Firearm Injuries?

BACKGROUND: Bullet-proof vests and helmets protect from harm in combat and military engagements. The use of armor against shrapnel has been studied, yet little has been documented as to how they protect from high velocity gunshots. This study aims to describe the medical consequences of high velocity firearm injuries and to differentiate between patients injured while using protective wear and those injured unprotected. STUDY DESIGN: National trauma registry data on injury characteristics, treatment and outcomes between October 1, 2000 and December 31, 2003 were retrieved and analyzed. RESULTS: There were 669 terror-related firearm injuries recorded: 236 (37.8%) in soldiers (protected) and 433 (62.2%) in civilians (unprotected). Injury severity was notably higher in civilian patients (31% versus 16% with Injury Severity Score>or=16). Civilians had more ICU care (26% versus 20%, p=0.06), and double the inpatient mortality (8.6% [n=37] versus 3.4% [n=8] patients). Protected body regions such as abdomen, chest, and brain, were injured less frequently. Once a traumatic brain injury was sustained, no statistical differences were found in severity distribution, ICU stay, or inpatient death between protected and unprotected patients. But injury severity in patients with chest injuries was much higher in those who were unprotected (Injury Severity Score>or=25, 41% versus 23%, respectively, p=0.08). This increased severity could be attributed partly to more multiple injuries involving the chest. Abdominal injuries showed a similar pattern. CONCLUSIONS: Body armor has a protective effect on victims of high velocity gunshot wounds; lower rates of head, brain, chest, and abdominal injuries are seen. In addition, armor reduces the severity of injuries to the chest and the abdomen.     

War injuries during the Gulf War: experience of a teaching hospital in Kuwait.

The war injuries of 361 patients admitted to Mubarak Al-Kabeer Teaching Hospital, during the Gulf War are reported. More abdominal and chest injuries were seen in this series in comparison with other conflicts owing to the short evacuation time. Of the injuries, 54% were caused by gunshots, 34% were fragment injuries and 5.5% were glass and stab injuries. Civilians accounted for 50% of the injured. Wound infection rate was 7%, average hospital stay was 8.8 days and hospital mortality was 5.5%. We advocate radical wound excision, exploration of penetrating wounds of neck and abdomen, and mainly conservative management of chest injuries that do not involve the mediastinum.     

CT as a first-line modality in elderly patients with stable blunt chest trauma

Purpose: Blunt thoracic injuries are common among elderly patients and may be a common cause of morbidity and death from blunt trauma injuries. We aimed to examine the impact of chest CT on the diagnosis and change of management plan in elderly patients with stable blunt chest trauma. We hypothesized that chest CT may play an important role in providing optimal management to this subgroup of trauma patients. Methods: A retrospective analysis was performed on all the admitted adult blunt trauma patients between January 2014 and December 2018. Stable blunt chest trauma patients with abbreviated injury severity (AIS) < 3 for extra-thoracic injuries confirmed with chest X-ray (CXR) and chest CT on admission or during hospitalization were included in the study. The AIS is an international scale for grading the severity of anatomic injury following blunt trauma. Primary outcome variables were occult injuries, change in management, need for surgical procedures, missed injuries, readmission rate, intensive care unit (ICU) and length of hospital stay. Results: There are 473 patients with blunt chest trauma included in the study. The study patients were divided into two groups according to the age range: group 1: 289 patients were included and aged 18-64 years; group 2: 184 patients were included and aged 65-99 years . Elderly patients in group 2 more often required ICU admission (11.4% vs. 5.2%), had a longer length of ICU stay (days) (median 11 vs. 6, p = 0.01), and the length of hospital stay (days) (median 14 vs. 6, p = 0.04). Injuries identified on chest CT has led to a change of management in 4.4% of young patients in group 1 and in 10.9% of elderly patients in group 2 with initially normal CXR. Chest CT resulted in a change of management in 12.8% of young patients in group 1 and in 25.7% of elderly patients in group 2 with initially abnormal CXR. Conclusion: Chest CT led to a change of management in a substantial proportion of elderly patients. Therefore, we recommend chest CT as a first-line imaging modality in patients aged over 65 years with isolated blunt chest trauma.     

Abdominal Trauma in Durban,South Africa: Factors Influencing Outcome

Abdominal injury as a result of both blunt and penetrating trauma has an appreciable mortality rate from hemorrhage and sepsis. In this article, we present our experience with the management of abdominal trauma in Durban and investigate factors that influence outcome. We performed a prospective study of patients with abdominal trauma in one surgical ward at King Edward VIII Hospital in Durban over a period of 7 years, from 1998 through 2004. Demographic details, cause of injury, delay before surgery, clinical presentation, findings at surgery, management and outcome were documented. There were 488 patients with abdominal trauma with a mean age of 29.2 ± 10.7 years. There were 440 penetrating injuries (240 firearm wounds; 200 stab wounds) and 48 blunt injuries. The mean delay before surgery was 11.7 ± 16.4 hours, and 55 patients (11%) presented in shock. Four hundred and forty patients underwent laparotomy, and 48 were managed nonoperatively. The Injury Severity Score was 11.1 ± 6.7, and the New Injury Severity Score was 17.1 ± 11.1. One hundred and thirty-seven patients (28%) were admitted to the intensive care unit (ICU), with a mean ICU stay of 3.6 ± 5.5 days. One hundred and thirty-two patients developed complications (28%), and 52 (11%) died. Shock, acidosis, increased transfusion requirements, number of organs injured, and injury severity were all associated with higher mortality. Delay before surgery had no influence on outcome. Hospital stay was 9.2 ± 10.8 days. The majority of abdominal injuries in our environment are due to firearms. Physiological instability, mechanism of injury, severity of injury, and the number of organs injured influence outcome.     

Clinical study on stab wounds of chest--factors that may influence their mortality

Stab wounds of the chest occupy an important position in penetrating thoracic injuries in Japan. A retrospective review of 117 patients with stab wounds of the chest admitted to our hospital over the past 12 years (from 1975 to 1987) revealed some factors that might influence their mortality. Seven patients died from trans-diaphragmatic injuries of intra-abdominal organs. The management of intra-abdominal injuries was very important in thoracic stab wounds. Many of the patients with stab wounds of the precordial chest (danger zone) had cardiac or major vascular injuries, and the mortality rate of them was high. The mortality rate of the patients with stab wounds of the right lateral thorax was high, because many of them had trans-diaphragmatic liver injuries. We thought that right lateral thorax as well as precordial chest is the danger zone in thoracic stab wounds. Survival rate in the patients whose circulatory condition had been unstable when they admitted was very low. Five DOA (dead on arrival) patients with stab wounds of the chest required emergency room thoracotomy (ERT). One of them survived. Survival rate in the DOA patients with stab wounds of the chest was higher than that in the DOA patients with blunt thoracic injuries. ERT for cardiac insufficiency following stab wounds of the chest was thought an effective procedure for surviving. Survival rate of the patients with cardiac stab wounds was 63.6 per cent.     

Penetrating neck injuries: analysis of experience from a Canadian trauma centre.

OBJECTIVE: To study the demographics and treatment outcome of penetrating neck injuries presenting to a major trauma centre in order to develop a treatment protocol. DESIGN: A case review. SETTING: A trauma centre at a tertiary care institution. PATIENTS: One hundred and thirty consecutive patients who had 134 neck wounds penetrating the platysma and presented to the trauma service between 1979 and 1997. INTERVENTION: Surgical exploration or observation alone. MAIN OUTCOME MEASURES: The location of injury, patient management, number of significant injuries, duration of hospital stay and outcome. RESULTS: Injuries were caused by stab wounds in 124 patients (95%) and gunshot wounds in 6 (5%). The location of injury was zone I (lower neck) in 20 cases (15%), zone II (midportion of the neck) in 108 (81%) and zone III (upper neck) in 5 (4%). The location was not recorded in 1 case. Fifty patients were managed by observation alone and 80 were managed surgically. Neck exploration in 48 asymptomatic patients was negative in 32 (67%). Significant injuries, including major vascular (12), nerve (13) and aerodigestive tract (19) injuries, were identified in 34 patients. Two of the 130 patients (1.5%) died of major vascular injuries. Seventy-six percent of significant injuries, including all zone II major vascular injuries, were symptomatic on presentation. The mean (and standard deviation) hospital stay for asymptomatic patients treated with observation alone and surgical exploration was similar (3.5 [6.02] versus 4.3 [5.46] days respectively, p = 0.575). Long-term disability, all neurologic in nature, was documented in 3 patients managed by observation alone and 6 patients managed by surgical exploration. CONCLUSIONS: Penetrating neck trauma, in particular stab wounds to zone II in asymptomatic patients, is associated with low morbidity and mortality. A selective management protocol with investigations directed by symptoms is the most appropriate approach for the patient population and resource base in this setting.     

Management of penetrating lung injuries in civilian practice

Recent reports of military thoracic injuries have advocated early thoracotomy and aggressive management of pulmonary injuries with resection as opposed to the more conservative and traditional treatment with chest tube thoracostomy. A retrospective study was therefore performed to determine the incidence of thoracotomy and lung resection in civilian injuries and to evaluate the effectiveness of treatment of these injuries. Between 1973 and 1985, in a series of 1,168 patients, there were 384 gunshot wounds and 784 stab wounds to the thorax. Two hundred eighty-three patients with a gunshot wound (74%) and 602 with a stab wound (77%) were treated with chest tubes alone. Sixty-eight patients (6% of the total) required operative repair of pulmonary hilar or parenchymal injury. Pulmonary resection was necessary in only 18 patients (nine with a gunshot wound and nine with a stab wound), and 10 patients had repair of hilar injuries (nine with a gunshot wound and one with a stab wound). Of patients requiring pulmonary resection, nine required wedge or segmental resection, six required lobectomy, and three patients required pneumonectomy. Mortality for all thoracic injuries was 2.3%: for those treated with chest tube alone, 0.7%; for pulmonary hilar injuries, 30%; for pulmonary parenchymal injuries, 8.6%; and for injuries necessitating lung resection, 28%. Most civilian lung injuries can be treated by tube thoracostomy alone. Although relatively few patients with primary pulmonary injury require thoracotomy, those that do are at significant risk and may require lung resection to control bleeding or hemoptysis or to remove destroyed or devitalized lung tissue.     

Trends in the incidence and severity of stab wounds in Sweden 1987-1994.

OBJECTIVE: To evaluate the incidence, types of injury, medical consequences, and mortality of patients with stab wounds in Sweden. DESIGN: Retrospective case study. SETTING: The Swedish National Hospital Discharge Register (SNHDR) and the Register of Causes of Death, Statistics Sweden (RCDSS) SUBJECTS: 1315 patients with stab wounds. All 1507 episodes were treated in Swedish hospitals from 1987-1994. MAIN OUTCOME MEASURES: Incidence of stab wounds in Sweden, mortality, types of injuries and medical consequences. RESULTS: From 1987 to 1994, 1315 people were admitted to Swedish hospitals with stab wounds, which corresponds to 2.1 injuries/100,000 population/year. In all, 1507 episodes were treated in hospital. There were 1121 men (85%) and 194 women (15%), with a median age of 32 years (range 1-88). The annual incidence was relatively constant during this period. The total number of deaths was 45/1315 (3.4%). Among these, 13 (29%) had thoracic, 9 (21%) abdominal, 7 (16%) head/neck and 7 (15%) extremity injuries. Twenty percent of those admitted to hospital had to spend more than one week there. CONCLUSIONS: The incidence of stab wounds was low and the annual incidence stable. Young men in urban areas were the commonest victims. Injuries of the trunk were commonest, followed by injuries to the head and neck and limbs, 80% of the patients were discharged from hospital within a week, and 3% of those treated in hospital for stab wounds died.     

Chest injuries in children: an analysis of 100 cases of blunt chest trauma from motor vehicle accidents.

One hundred twenty-eight cases of chest injury were seen in a Paediatric Trauma Unit over a 5 1/2-year period. One hundred patients sustained motor vehicle accident (MVA)-related blunt chest injuries, 91 of them as pedestrians. Nine children had blunt chest injuries from falls, 10 had stab wounds (3 assault, 7 accidental), and 9 had gunshot injuries (6 from birdshot used by police during civil disturbance). MVA-related injuries were studied separately, as an etiologically homogeneous group. Sixty-five of these patients were under the age of 6. All but 3 also had serious extrathoracic injuries. The mean injury severity score (ISS) in MVA-related injuries was 25. Eight patients died, all with an ISS of 34 or more, 7 of whom had fatal head injuries. In MVA-related injuries, pulmonary contusion (n = 73) was the most frequent lesion seen, followed by rib fracture (n = 62), posttraumatic effusion (n = 58), pneumothorax (n = 38), and pneumatocele (n = 5). In MVA-related injuries, 18 children required ventilation. Thirty-nine (69%) of 56 children with radiologically evident posttraumatic pleural effusion had intercostal chest drainage. Analysis suggests that lung injury is a central event in MVA-related blunt chest trauma. Primary lung injury, radiologically visible as contusion, is complicated by hematoma, posttraumatic effusion, and pneumothorax.     

Chest trauma in children.

OBJECTIVES: Chest trauma in childhood is uncommon in clinical practice. The management and treatment principles of children with thoracic trauma were discussed with the data reported in the literature. METHODS: Of the chest injury diagnosed in 1653 patients, 225 were children in the last 17-year period. There were 199 boys (88.44%) and 26 girls (11.55%). The most common causes were blunt injuries in 135 cases (60%), stab wounds in 67 cases (29.77%) and gunshot wounds in 22 cases (9.77%). RESULTS: Out of 225, 217 patients were treated conservatively and eight patients were treated surgically. There was no mortality and morbidity. CONCLUSIONS: The prevalence of chest trauma in children due to blunt injuries is high in Turkey. Extremity injury is thought to be the most commonly associated extra-thoracic injury. However, thoracic trauma in children can be managed conservatively in most of the cases.     

Stab wounds to the gluteal region: a management strategy

OBJECTIVE: To examine the utility of a protocol for treating stab wounds to the gluteal region. These are uncommon and potentially lethal, and the location of injury influences the rate and severity of associated injuries. This was a retrospective, uncontrolled study. METHODS: Patients who sustained gluteal stab wounds and were treated according to our predetermined protocol that classifies injuries as upper or lower zone were reviewed, and associated injuries and outcome were measured. RESULTS: Of 27 gluteal stab wounds in 17 patients, 53% were classified as upper zone and 47% as lower zone injuries. Sixty-six percent of the upper zone injuries had associated neurologic, vascular, or visceral injuries that required invasive procedures or surgery, compared with 12.5% for lower zone injuries (p < 0.05). CONCLUSION: Upper zone gluteal stab wounds require prompt multisystem evaluation with mandatory angiography and aggressive management. Lower zone wounds need observation and repeated evaluations.     

Laparotomy for penetrating gastric trauma - A South African experience

IntroductionPenetrating gastric injury (PGI) is common and although primary repair is sufficient for most injuries, several areas surrounding the peri-operative management remain contentious. This study reviews our experience in the management of PGI and review the clinical outcome at a major trauma centre in South Africa.Materials and methodsA retrospective study was conducted from January 2012 to April 2020 at a major trauma centre in South Africa.Results210 cases were included (184 male, median age: 30 years). Mechanism of injury was 59% stab wounds (SWs) and 41% gunshot wounds (GSWs). The AAST grade was predominantly (92%) grade 2 for all cases. 20% (41/210) were isolated gastric injuries. All cases underwent primary repair and there were no cases of suture line failure. Eleven cases (5%) had one or more injuries not identified at the index laparotomy: 7 were unidentified gastric injuries and the remaining 4 were unidentified non gastric injuries. There was no association between unidentified injuries and mechanism of injury or outcome. Fifty-seven (27%) cases experienced one or more complications. Eighty-two cases (39%) required intensive care unit admission. The overall median length of hospital stay was 7 (IQR 4-11) days. The overall mortality was 14%. GSW injuries were more likely to have additional organ injury, higher ISS and PATI scores, longer length of hospitalization, higher likelihood of ICU stay, greater morbidity and mortality than SW injuries. There was a slight increase in the wound sepsis rate as number of associated extra gastric injuries increased but this was not statistically significant. There was no difference in wound overall sepsis rate between SW and GSW injuries (2% vs 8%, p=0.121).ConclusionsPrimary repair alone is sufficient for most PGI, but laparotomy is associated with high incidence of unidentified injury and surgeons must to be cognisant of the likelihood of these occult injuries.     

Management of gunshot wounds at a Sydney teaching hospital

BACKGROUND: Injuries caused by firearms account for only a small percentage of trauma admissions and deaths in Australia but are frequently the subject of media and public attention. The present study examines the epidemiology and management of firearm injuries presenting to St Vincent's Hospital, which is located at the edge of the central business district of Sydney. METHODS: The medical records of all patients presenting to St Vincent's with a gunshot wound (GSW) from January 1988 to December 1998 were analysed. Additional details were acquired from New South Wales State Coroner's Court reports and media archives, especially major newspapers. RESULTS: Seventy-four patients presented to St Vincent's Hospital with 103 GSW. The age (mean +/- SD) was 31+/-11 years. Sixty-seven patients (91%) were male. Alcohol was identified as a factor in 24 cases (32%) while other drugs were indicated in four cases (5%). Ten patients (14%) had intentionally self-inflicted wounds, seven (9%) had accidental wounds and 57 (77%) had wounds that were caused by crime-related violence. Sixty patients (81%) underwent operation for their injury. Thirty complications were seen in 18 patients (24%). Eleven patients (15%) died. The length of hospital stay (mean +/- SEM) was 18+/-9 days. CONCLUSIONS: The incidence of trauma due to firearms has not increased at St Vincent's hospital in the period 1988-98. Most GSW were inflicted in the setting of criminal violence, with a high proportion due to handguns. Patients were mostly young men, and alcohol or other drugs were frequently involved. Outcomes are comparable to other centres managing large volumes of penetrating trauma.     

Pneumothorax of late onset after chest stabbings

Pneumothorax is a well known immediate complication of penetrating chest injuries, but its late occurrence is not widely recognized. In a retrospective study of 56 patients who sustained stab wounds of the chest, 6 (10 per cent) developed pneumothorax between twelve hours and three days after injury. Combined thoraco-abdominal stab wounds were present in three patients and surgical emphysema was also apparent in three other patients. We conclude that pneumothorax of late onset may be commoner than has been suspected and this emphasizes the need for observation in hospital for 48 h and for serial radiography of the erect chest to detect this dangerous complication.     

Penetrating trauma to the back and flank. A reassessment of mandatory celiotomy

The optimum management of penetrating wounds to the back and flank remains controversial. Since 1980 our institution has followed a policy of mandatory celiotomy for back and flank wounds with evidence of fascial penetration. Following this policy, 34 patients underwent celiotomy for back (8), flank (22), or combined (4) area penetrating injuries. Four patients sustained shotgun blasts, eight sustained handgun or rifle injuries, and 22 patients were stabbed. All shotgun blasts caused multiple intra-abdominal injuries and five (63%) of the eight gunshot victims had significant intra-abdominal injuries. Only one (5%) of the 22 stab victims had significant intra-abdominal injury. Four (12%) patients died, three of shotgun injuries. One patient had a small bowel obstruction 1 month after a noncontributory abdominal examination. Based on this review, the authors recommend selective management of stab wounds to the back and flank. Gunshot wounds continue to warrant mandatory exploration.     

Wounding patterns in pediatric firearm fatalities

IntroductionPediatric firearm injury became the leading cause of death among U.S. children in 2020. Studies evaluating wounding patterns in military and mass casualty shootings have provided insights into treatment and potential salvageability in adults, however, similar studies in the pediatric population do not exist. Hence, our study aimed to analyze wounding patterns of pediatric firearm fatalities and associated demographics and characteristics, such as place of death, to better understand pediatric firearm injuries, potential salvageability, and opportunities to reduce firearm deaths among vulnerable pediatric populations.MethodsA retrospective review of the National Violent Death Reporting System from 2005-2017 was performed on patients 18 and younger. Mortalities were stratified by patient age: <12 years and 13-18 years and by intent— homicide, suicide, and unintentional. Comparative and exploratory analyses of demographics, location of death and anatomic location of wounds were performed.ResultsOf 8,527 pediatric firearm mortalities identified, 4,728 were homicides, 3,180 were suicides and 619 were unintentional injuries. Suicide victims were most likely to be dead on scene and >90% of suicide victims suffered head/neck injuries. For victims of homicide, younger children were more likely to die on scene (61% vs 44% p < 0.001). The pattern of injury in homicides differed for younger children compared to adolescents, with younger children with more head/neck injuries and older children more thoracic, thoracoabdominal, abdominal, and junctional injuries. In both age groups, children with extremity, abdominal and thoracoabdominal injuries were more likely to die later in the emergency department or inpatient setting.ConclusionsWounding patterns across pediatric firearm mortalities in the U.S. vary by age and intent. The majority of pediatric firearm deaths were due to head/neck injuries. Children with homicide and unintentional deaths had more wounding pattern variation, including more injuries to the thorax and abdomen, and a much lower rate of dead-on scene than suicide victims. Our study of wounding patterns among U.S. children killed by firearms highlights the complexity of these injuries and offers opportunities for tailored public health strategies across varying vulnerable pediatric populations.
