Pediatric all-terrain vehicle trauma: a 5-year statewide experience

BACKGROUND/PURPOSE: This is a retrospective review of the pediatric all-terrain vehicle trauma victims who presented to the five major trauma centers serving the state of West Virginia during the 5-year period from January 1991 to December 1995. The purpose of this research is to characterize the nature of the injuries and the individuals injured to better appreciate the magnitude of the problem of ATV-related injuries in the pediatric population. METHODS: This study is a retrospective review of these 218 consecutive pediatric patients from trauma registry data and their medical records. RESULTS: Two hundred eighteen patients between the ages of 2 years and 16 years presented during the study period. Boys outnumbered girls three to one. The average Injury Severity Score (ISS) was 8.76, the average Glasgow Coma Score (GCS) was 14.4, and the average Trauma Score (TS) was 15.2. The most common injuries were orthopedic followed by head and facial injuries. The majority of the children did not wear helmets, and their injuries resulted in an average hospital length of stay of 4.3 days. Thirty-eight percent of the children required surgery. There were a total of four deaths for a mortality rate of 1.8%. The estimated total hospitalization cost for the 218 patients was $1,918,400.00. CONCLUSIONS: All-terrain vehicle-related trauma remains an ongoing safety concern facing society today. Every physician who cares for children should address this important issue when talking to children and parents about safety issues and injury prevention.     

Influence of urinary management on urologic complications in a cohort of spinal cord injury patients

OBJECTIVE: To study urologic complications in patients with spinal cord injury (SCI) in relation to their bladder management. DESIGN AND SETTING: A cohort study of patients with SCI in a rehabilitation center. PARTICIPANTS: One hundred eighty-two patients were studied; demographic data, disease characteristics, and urologic history were obtained for each. INTERVENTION: Patients responding to a questionnaire were given a clinical exam. Their medical records were reviewed, with particular attention given to the following urologic complications: lithiasis, urinary infections, orchiepididymitis, urethral trauma, vesicorenal reflux, and renal failure. RESULTS: Results are reported for 123 patients. Time since SCI was 8 years. Intermittent catheterization was the main method of bladder management. Only 32 patients had changed their method of vesical voiding. Urinary complications had developed in 75% of patients. The most common complication was urinary infection. Vesicoureteral reflux occurred in 26% of patients using percussion. Trauma related to catheterization was the main problem with intermittent catheterization, responsible for a high rate of orchiepididymitis. CONCLUSION: Intermittent catheterization is the most-used method of bladder management, but with a nonnegligible rate of urethral trauma in men. Percussion and Credé maneuver appear to be acceptable techniques of bladder management if the patient is closely monitored.     

Does free fluid on abdominal computed tomographic scan after blunt trauma require laparotomy?

BACKGROUND: Abdominal computed tomographic (CT) scans are used in the evaluation of blunt trauma. The purpose of this study was to determine if isolated intraperitoneal fluid seen on CT scan necessitates laparotomy. METHODS: Trauma registry records of patients who underwent abdominal computed tomography from January 1994 through January 1997 were studied. Data were reviewed for age, gender, CT scan interpretation, associated injuries, and operative findings. RESULTS: Abdominal injury was identified in 126 patients. Seventy-eight patients had evidence of solid-organ injury and 17 patients had extraperitoneal injury. Isolated intraperitoneal fluid was identified in 31 patients. All patients with isolated fluid underwent laparotomy; 29 of these procedures (94%) were therapeutic. Bowel injuries occurred in 18 patients and mesenteric injuries in 8 patients. Five patients had intraperitoneal bladder rupture, and undetected solid-organ injuries were found in two patients. Other organs injured included the stomach, pancreas, ovary, and uterus. CONCLUSION: Exploratory laparotomy was therapeutic in 94% of patients. Isolated intraperitoneal fluid on CT scan after blunt trauma mandates laparotomy.     

Results of treatment of multiple trauma in 130 children

Trauma remains the leading cause of death in the pediatric age group, despite recent advances in prevention and treatment. We retrospectively analyzed 130 cases of multiple trauma among 725 pediatric patients with injuries treated here during 1988-1989. Road accidents and falls from heights were the most common causes of injury. Mean age was 7 years (range 0.5-15) and the male to female ratio 2.7:1.0. Overall mortality was 9.2%. 57 patients (44%) did not get any prehospital medical care and 5 of them with injury severity scores (ISS) greater than 25 died. In contrast 11/18 (61%) of patients with ISS greater than 25 who were treated by medical teams survived. On arrival at the emergency room, 15% were hypothermic ( < 34 degrees C), and 6 were in hypovolemic shock--5 of whom died. Most common injuries were head trauma (91), limb injuries (69), abdominal trauma (34) and thoracic trauma (34). In 39 injury was severe, with pediatric trauma score (PTS) 6 or less, 12 of whom died. All deaths except 1 were associated with severe head injury and with ISS more than 25. There was no mortality in those with PTS more than 7 or ISS less than 25. Thus, the prehospital care of pediatric patients with head injury is associated with high mortality. Absence of mortality in patients with PTS of more than 7 emphasizes the importance of designated trauma centers for these patients.     

Fetal biparietal diameter as a predictor of a mature lecithin/sphingomyelin ratio

There was a 20 per cent mortality rate of 193 patients with bladder injury and in 94 percent of all patients there were associated injuries that caused the deaths. Blunt external trauma was responsible for 95 per cent of the injuries. Cystography revealed a falsely negative result in 3 patients with extraperitoneal rupture. Management of the 29 intraperitoneal, 36 extraperitoneal and 2 intraperitoneal and extraperitoneal ruptures comprised vesical repair and drainage in 60 patients, urethral catheter alone in 1 patient and no treatment in 6 in whom the rupture was found at autopsy. The advantages and disadvantages of urethral catheter drainage are discussed. Early diagnosis and treatment of bladder rupture are important if the significant mortality is to be reduced.     

Genetic diversity in northern Spain (Basque Country and Cantabria): GM and KM variation related to demographic histories

Uroperitoneum (UP) was diagnosed in 26 cats. Trauma was the most common cause (84.6%), including blunt abdominal trauma (59.1%), urethral catheterization (31.8%), and bladder expression (9.1%). The bladder was the most frequent site of urine leakage following blunt abdominal trauma (84.6%), while the urethra was the most common site following catheterization (71.4%). Common historical complaints were anuria (53.8%) and vomiting (50%). On physical examination, the bladders were palpable in nine (69%) of 13 cases; four of the nine had ruptured bladders. The ability to urinate did not exclude a diagnosis of UP since four noncatheterized cases reportedly urinated. Twenty-five cases were azotemic on presentation. The creatinine or potassium (K+) concentration in the serum compared to that in the peritoneal effusion (mean ratio, 1:2 and 1:1.9, respectively) was a useful indicator for UP. When performed, positive contrast radiography was diagnostic. Drainage of urine from the peritoneal cavity appeared to improve patient stabilization. Morbidity and mortality depended largely on the severity of associated injuries.     

Pediatric penetrating thoracic trauma: a five-year experience

Penetrating thoracic trauma is managed nonoperatively in 85% of adult patients. We hypothesized that similar trauma in children would lead to proportionately more vital tissue damage and a higher rate of operative intervention. The pediatric penetrating thoracic trauma experience of a level one trauma center was analyzed over a five-year period. Data reviewed included circumstances of injury, Pediatric Trauma Score (PTS), interventions performed, and outcome. Of 61 children with thoracic trauma, 13 had penetrating injuries. Of these 13, seven were unintentional (five from firearms); the rest were caused by assaults. Seven patients (54%) underwent thoracotomy or laparotomy. All five patients with a PTS < 8 underwent surgical intervention, whereas only two of the eight patients with a PTS > or = 8 needed surgery (P < 0.05). There was one death. We reached the following conclusions: 1) Children with penetrating thoracic trauma are more likely to require surgical intervention than adults. 2) Penetrating thoracic trauma in children should elicit a thorough search for operative lesions. 3) About half these injuries are unintentional, and thus potentially preventable.     

Obstructed labor injury complex: obstetric fistula formation and the multifaceted morbidity of maternal birth trauma in the developing world

Prolonged obstructed labor may produce injuries to multiple organ systems. The best known, and most common, of these injuries is obstetric fistula formation. When obstructed labor is unrelieved, the presenting fetal part is impacted against the soft tissues of the pelvis and a widespread ischemic vascular injury develops that results in tissue necrosis and subsequent fistula formation. Unlike the postsurgical vesicovaginal fistula, however, which is usually the result of focal trauma to otherwise healthy tissues, the obstetric fistula is the result of a "field injury" to a broad area. The field injury that is produced by prolonged obstructed labor may result in multiple birth-related injuries in addition to (or instead of) a vesicovaginal fistula. Focusing simply on the "hole" between the bladder and the vagina ignores the multifaceted nature of the injury that many of these patients have sustained. These injuries may include total urethral loss, stress incontinence, hydroureteronephrosis, renal failure, rectovaginal fistula formation, rectal atresia, anal sphincter incompetence, cervical destruction, amenorrhea, pelvic inflammatory disease, secondary infertility, vaginal stenosis, osteitis pubis, and foot-drop. In addition to their physical injuries, women who have experienced prolonged obstructed labor often develop serious social problems, including divorce, exclusion from religious activities, separation from their families, worsening poverty, malnutrition, and almost unendurable suffering. Isolated almost exclusively to the developing world, particularly Africa, this problem has not received the international attention that it deserves, from either a medical or a social standpoint.     

Pediatric hepatic trauma: does clinical course support intensive care unit stay?

PURPOSE: The objective of this study is to determine if grade of liver injury predicts outcome after blunt hepatic trauma in children and to initiate analysis of current management practices to optimize resource utilization without compromising patient care. METHODS: A retrospective review of 36 children who had blunt hepatic trauma treated at a pediatric trauma center from 1989 to present was performed. Hepatic injuries graded (AAST Organ Injury Scaling) ranged from grade I to IV. Injury Severity Score (ISS), Glasgow Coma Score (GCS), transfusion requirements, liver transaminase levels, associated injuries, intensive care unit (ICU) length of stay, and survival were analyzed. RESULTS: Mean (+/-SEM) age was 6.6+/-0.8 years, mean grade of hepatic injury was 2.4+/-0.2, mean ISS was 17+/-2.6, mean GCS was 13+/-1, and mean transfusion was 15.4 mL/kg of packed red blood cells (PRBC). There were three deaths with a mean ISS of 59+/-9 and a mean GCS of 3+/-0. Death was not associated with a high-grade liver injury, survivors versus nonsurvivors, 2.3+/-0.2 versus 2.7+/-0.3, but was associated with ISS, 13+/-1.4 versus 59+/-9 (P = .005) and GCS, 14+/-1 versus 3+/-0 (P = .005). Only one patient (grade III, ISS = 43) underwent surgery. There were no differences in mean ISS or GCS between grades I to IV patients. The hepatic injury grades of patients requiring transfusion versus no transfusion were significantly different, 3.4+/-0.2 versus 2.2+/-0.2 (P = 0.04). Abused patients had high-grade hepatic injuries and significant laboratory and clinical findings. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were significantly higher in grade III and IV injuries than in grades I and II, 1,157+/-320 versus 333+/-61 (P= .02) and 1,176+/-299 versus 516+/-86 (P= .04), respectively. No children with grade I or II injury had a transfusion requirement or surgical intervention. There were no liver-related complications. CONCLUSIONS: Mortality and morbidity rates in pediatric liver injuries, grades I to IV, correlate with associated injuries not the degree of hepatic damage. ALT, AST, and transfusion requirements are significantly related to degree of liver injury. Low-grade and isolated high-grade liver injuries seldom require transfusion. Blunt liver trauma rarely requires surgical intervention. In retrospect, the need for expensive ICU observation for low-grade and isolated high-grade hepatic injuries is questionably warranted.     

Immediate management of posterior urethral disruptions due to pelvic fracture: therapeutic alternatives

PURPOSE: We retrospectively reviewed the results of 3 types of initial management of pelvic fracture urethral disruption in children. MATERIALS AND METHODS: From 1980 to 1994, 35 boys 2 to 15 years old (mean age 8.1) with prostatomembranous urethral disruption were treated, including 17 who also had associated injuries. Immediate treatment included suprapubic cystostomy and delayed urethroplasty in 19 patients (group 1), urethral catheter alignment without traction and concomitant suprapubic cystostomy in 10 (group 2), and primary retropubic anastomotic urethroplasty in 6 (group 3). RESULTS: In all patients in groups 1 and 2 severe urethral obliteration developed. Four group 3 patients (66%) had a stricture at the site of anastomotic repair. After delayed urethroplasty 16 group 1 (84%) and all 10 group 2 patients were continent. However, only 3 group 3 patients (50%) achieved continence. Retrospectively associated bladder neck injury occurred in 5 of the 6 incontinent boys. Erections were observed before and after treatment in all but 3 children. Unstable pelvic ring fractures (type IV) comprised 28% of all pelvic fractures with a high rate of associated injuries. CONCLUSIONS: As described, urethral alignment was not beneficial for avoiding urethral obliteration. Therefore we recommend suprapublic cystostomy as the only form of initial treatment in these cases. Urinary incontinence seems more likely related to associated bladder neck rupture and the severity of pelvic fracture rather than to initial treatment or delayed urethral repair. Consequently, when associated bladder neck injury is present, we advocate immediate surgical repair.     

Immediate surgical treatment of major renal trauma

Of the 77 cases of renal trauma treated at Oulu University Central Hospital during the years 1965--1975, 60 injuries were minor and 17 severe. 73 of these injuries were closed and 4 penetrating. The rate of operative treatment in severe renal injuries was 88% minor renal injuries being treated conservatively. Primary exploration was done in 18 of the 77 cases and in all patients with penetrating injuries. Only 7 of the 73 patients with blunt trauma and one of the 4 patients with penetrating injury required nephrectomy, including one patient with renal carcinoma. 6 of the 77 patients died, most as a result of severe associated injuries, giving a mortality of 8%. None of the surviving patients treated for renal trauma suffered from major complications. In 13 of the 18 patients operated upon, renal injury was the main indication for operation. Operation was performed in 5 of the 18 patients after immediate radiological evaluation. The advantages of immediate surgical management in severe renal injuries are early and final treatment, short hospital stay, and low incidence of complications. Qualifications for emergency surgery are access to renal angiography and familiarity with reparative renal procedures.     

Quantitative changes in the ultrastructure of myocardial cells in Japanese quail during hypergravity, hypodynamia and space flight

To assess the consultation patterns of pediatric emergency physicians in the management of injured children and to describe the spectrum of pediatric trauma, we retrospectively reviewed 601 patients treated in the emergency department for injuries during four one-week periods at a designated level I regional pediatric trauma center (50,000 patients/year) with a pediatric emergency medicine fellowship. The majority (94%) of pediatric trauma was minor; only 2% of children had injuries severe enough to require direct transfer to the operating room. The highest volume of patients, the greatest number of consultations, and the majority of admissions to the operating room occurred between 4 PM and midnight. No patients went to the operating room on the night shift. Musculoskeletal injuries constituted the predominant category of pediatric trauma, and lacerations were the most common specific injury. One half of all procedures involved laceration repair, and one third involved splinting or casting. Four hundred ten patients (68%) were managed by physicians in the emergency department without consultation. The orthopedic service performed one half of all consultations and admitted the largest number of patients; the majority of patients taken directly to the operating room had musculoskeletal injuries.(ABSTRACT TRUNCATED AT 250 WORDS)     

Pediatric genitourinary trauma

Trauma is the leading cause of death in children in the United States, and blunt trauma is responsible in most cases. The kidney is the urogenital organ most frequently injured. Renal injuries are classified on a scale of I to V. Only grades IV and V injuries need operative intervention. CT is the preferred diagnostic imaging modality in most instances. Cystography and urethrography are necessary to diagnose bladder and ureteral injuries. Genital injuries sometimes are produced by sexual abuse, and the clinician must be alert to this possibility.     

Characteristics of pancreatic injury in children: a comparison with such injury in adults

A retrospective study of eight pediatric patients (under 15 years of age) who had pancreatic injuries was undertaken. Comparisons were made with 59 adult patients who sustained pancreatic injuries over the same 15-year period. All the pediatric injuries and 96.6% of the adult resulted from blunt abdominal trauma. Bicycle accidents (children, 75.0%; adults, 0%; P < .001) and automobile accidents (children, 0%; adults, 61.0%; P < .01) were the most common causes of pancreatic injury in the two groups. There was no significant difference in the incidence of abdominal pain or peritoneal irritation between the groups. However, abdominal pain in the adults was poorly localized. Isolated pancreatic injuries were noted in 62.5% of the pediatric patients and in 15.3% of the adult patients (P < .05). Associated intraabdominal injuries were present in 25.0% of the children and in 69.5% of the adults (P < .05). The duodenum was injured in two (25.0%) pediatric patients and in 10 (16.9%) adult patients. Whereas the duodenal injuries in pediatric patients were intramural hematomas without perforation in both cases, all but one of these injuries in adults were perforations or transections (P < .05). There was a significant difference in the type of pancreatic injury between the two groups (P < .05). Surgery was performed in 12.5% of the pediatric cases and in 78.0% of the adult cases (P < .01). There were no deaths among the pediatric patients, but 8.5% of the adults died in the hospital. The difference with respect to clinical course might be related to the differences in cause of injury.     

Computed tomography in injuries to the respiratory system in children. The correlation with adults

INTRODUCTION: Diagnostic imaging in emergency rooms may be inadequate and delayed, which makes chest traumas in children more severe and difficult to treat. We carried out a retrospective study on adults and children who had survived major chest traumas involving the respiratory tract to assess the differences between the two age groups and the role of emergency CT. MATERIAL AND METHODS: Our series consisted of fourteen children admitted to the emergency department for various accidents. Home accidents prevailed (9/14 = 64.3%). On admission, chest radiography was performed in most cases (11/14 = 78.6%); CT was carried out in 21.4% (3/14 patients). RESULTS: Trauma involved more organs in pediatric patients (11/14 = 78.6%) and lung involvement was always associated with other types of injury, namely contusion (14/14 = 100%), pneumothorax (11/14 = 78.6%), hemothorax (10/14 = 71.4%), tear (4/14 = 28.6%). CT corrected or integrated the radiographic findings of contusion focus in 67% (8/14) and that of pneumothorax in 63.6%; both patterns cannot be demonstrated otherwise. DISCUSSION: Mixed and multiple posterior parenchymal injuries with no rib fractures prevail in young subjects because their bones and ligaments are more elastic, which may lead to trauma underestimation. Tracheobronchial ruptures and pneumomediastinum are much more severe in children than in adults. Chest plain film is often the only diagnostic tool used, despite its major technical and interpretative limitations, also because skull and abdomen are the most investigated regions. Executive limitations are stronger in childhood, increasing the margin of error and the risk of delayed treatment. CT is as cost-effective as radiography and shows even the injuries missed or poorly depicted on conventional images; CT also gives accurate information on damage severity and nature. CONCLUSIONS: Traumatic injuries are more severe in pediatric patients due to their build and to biomechanical, clinical and management factors. Spiral CT should be considered the examination of choice to be performed in the emergency department equipped also for pediatric re-animation.     

Pediatric trauma registry: analysis of 1200 cases

OBJECTIVES: We developed the first Spanish Pediatric Trauma Registry in order to collect and evaluate information concerning aspects of injuries in our pediatric population. METHODS: From January'95 to September'97, 28,713 children younger than 16 years were treated in our Hospital for acute injury: 1,200 were admitted and included in our database. Our file-registry consists of 108 data points including: patient identification, type, place and mechanism of injury, pre-hospital care, transport, assessment on admission, severity scores, diagnostic studies, injuries, treatments and morbidity-mortality. RESULTS: Accidents were more frequent in males (69%) than in females. The age-group predominantly was 12-15 years old (34%). Accidents were more frequent in the street (35.3%) than at home (18.7%) or school (14%). Falls and traffic-related accidents were the leading cause of injury (38 and 21.1%, respectively). The 16.7% of cases had Pediatric Trauma Score < or = 8 (n = 201). The 3.6% of this sustained multiple trauma (43 cases with Injury Severity Score > or = 15). Musculoskeletal and head trauma was the most frequent (62 and 42.3%, respectively). Surgical or orthopedic procedures were performed in 678 patients (56.5%). Average length of stay were 4.8 days (range 1-93 days), and functional impairments at discharge were found in 33.9% of patients older than 3 years (n = 338). Mortality rate in our series was 0.5% (n = 6), and 13.9% in children with ISS > or = 15. CONCLUSIONS: The utility of this Registry is to know the epidemiology of our injured pediatric population, to review patient care, to develop prevention programs and to compare results with other centers so potential deficiencies can be identified and corrected.     

Surgical treatment of noniatrogenic trauma of the femoral arteries

Trauma to the femoral arteries corresponds to 30 percent of all arterial traumas. The authors reviewed 74 patients with noniatrogenic trauma of the femoral arteries treated from January 1991 to December 1993. Ages ranged from 11 to 50 years, with a mean of 24. Seventy-one patients were male and three female. Fifty-two patients (70.2 percent) were white, 20 (27 percent) were black and two (2.8 percent) were Asian. Trauma due to firearms had the highest incidence, with 61 cases (82.4 percent). Absence of pulse was the most frequent clinical symptom (62.5 percent). Severe ischemia, with risk of loss of limb, was found in 66.2 percent of the cases. The superficial femoral artery was impaired in 77 percent of the cases. A preoperative arteriography was performed on only five patients, victims of multiple penetrating trauma or an asymptomatic penetrating wound along a vessel passage. In six cases, arterial and venous ligature was the chosen procedure. In three cases, a primary arterial anantomosis was performed. Simple arterriorraphy was feasible in one patient. In 64 of the patients, a venous graft was undertaken using a segment of the inverted great saphenous vein withdrawn from the other lower limb. Fasciotomoy was used in 32 patients (43.2 percent), all of whom exhibited pasting of the lower limb muscles at admission. One patient died during the immediate postoperative period as the result of multiple organ failure caused by polytraumatism. Preservation of the limb was attained in 72 patients (97.3 percent) Severe, previously-incurred ischemia was responsible for the only two amputations, aggravated by an exceedingly long delay between the time of injury and surgery. One of these patients, in addition to severe ischemia, had extensive injuries to the soft tissues. We conclude that trauma of the femoral arteries, attended while the limb still maintains its vitality, has a positive clinical outcome with a high rate of limb preservation. Mortality usually results from injury to other organs.     

Renal gunshot wounds: methods of salvage and reconstruction

Over the past 14 years, 2079 patients have been seen at our institution with renal trauma. Of these, 84 sustained gunshot wounds (81 unilateral, 3 bilateral; a total of 87 renal units). We evaluated this group to characterize the nature of their injuries and establish a methodology for renal salvage and reconstruction. Preoperative radiographic staging was performed with excretory urography (IVP) or computed tomographic (CT) scanning. The injuries were classified into five categories: 16 contusions (18.4%), 12 minor lacerations (13.8%), 44 major lacerations (50.5%), six vascular injuries (6.9%), and nine combination laceration and vascular injury (10.3%). Most patients had multiple organ injuries, with 79 requiring associated surgical procedures (94%). The mean injury Severity Score (ISS) was 26.7 (range, 4-59). Based on radiographic and clinical staging criteria, 69 renal injuries were surgically explored (79.3%), and 12 patients underwent nephrectomy (13.8%). Forty-six renal units were reconstructed (66.6%) by various methods, including renorrhaphy, omental pedical flaps, mesh or peritoneal patch grafts, partial nephrectomy, and vascular repair. Overall, 75 renal units were salvaged (86.2%). Early renal vascular control was achieved in all patients who underwent renal exploration. Follow-up functional studies were done in 24 (28.5%): none had delayed nephrectomy or postinjury hypertension. Overall, 79 patients survived (94%); however, mortality was not related to renal injury. These findings suggest that aggressive radiographic staging coupled with early vascular control and careful selection of reconstructive techniques can ensure a high renal salvage rate in patients with renal gunshot injuries.
