Injuries from falls in the pediatric population: an analysis of 729 cases.

BACKGROUND/PURPOSE: Falls are classified as low or high level for triage purposes. Because triage criteria dictate less urgency for low-level falls, this classification scheme has important implications for pediatric emergency care. METHODS: Retrospective analysis was conducted of 729 (393 low-level and 336 high-level) pediatric patients treated for fall-related trauma (1992 through 1998). Falls were classified as low (<15 feet) or high-level (> or =15 feet). All falls were reported as accidental or unintentional. RESULTS: The overall mortality rate was 1.6% (2.4% for high-level falls compared with 1.0% for low-level falls). All 4 patients who died of a low-level fall had an abnormal head computed tomography (CT) scan and intracranial hypertension. Half of deaths from high-level falls were attributable to intracranial injuries, and half were caused by severe extracranial injuries. Common extracranial injuries were upper extremity fracture (6.2%), lower extremity fracture (5.6%), pulmonary contusion (1.8%), pneumothorax (1.1%), liver laceration (1.1%), bowel injury (1.0%), and splenic injury (2.1%). Orthopedic and thoracic injuries resulted more commonly from high-level falls, whereas abdominal injuries were as likely to occur after a low-level fall. CONCLUSIONS: Intracranial injury accounts for the majority of deaths from falls. Children suffering low-level falls were at similar risk for intracranial and abdominal injuries compared with those who fell from greater heights. Pediatric trauma triage criteria should account for these findings.

The Trauma Program Manager role: a current examination.

PURPOSE: To describe the history and define current application of the Trauma Program Manger (TPM) role. To suggest that a professional networking group can assist a TPM to accomplish the significant demands of the role. SIGNIFICANCE TO CARE: Improved understanding of the current role. Enhanced effectiveness in fulfilling the current functions of the TPM role through networking. DESIGN: Literature review on the role of the TPM, discussing the growth, development and progression to its current form. Evaluation of one professional group of TPMs and how it aided members in accomplishing the significant demands of the role. METHODS OF EVALUATION: A 6-year retrospective review of the administrative records for a professional networking group of TPMs was conducted. Meeting content was sorted and tabulated into the 10 functional requirements of the TPM role. TPMs who were members of the group during the same 6-year period were surveyed regarding the perceived value of group participation relative to accomplishing each of the TPM role functions. CONCLUSIONS: The current form of the TPM role is significant and encompasses at least 10 distinct functions. A professional group of TPMs is a useful tool to aid individuals in fulfilling their TPM roles. This may be true for both novice and experienced TPMs. The professional group may serve as an adjunct to obtaining formal role education.

Cardiac and great vessel injuries in children after blunt trauma: an institutional review.

PURPOSE: The purpose of this study was to review the incidence of cardiac and great vessel injury after blunt trauma in children. METHOD: A retrospective review of 2,744 patients with injuries from blunt mechanisms was performed. RESULTS: Eleven patients sustained cardiac injury. Four patients had clinically evident cardiac contusions. All recovered. Four patients who died from central nervous system injury were found to have cardiac contusions at autopsy. None had clinical evidence of contusion before demise. One patient had a traumatic ventricular septal defect (VSD) that required operative repair. Autopsy findings showed a VSD in another patient, and a third patient was found to have a ventricular septal aneurysm that was treated medically. Two patients had great vessel injuries. One patient had a contained disruption of the superior vena cava that was managed nonoperatively. Another patient had a midthoracic periaortic hematoma without intimal disruption found at autopsy. One patient had cardiac and great vessel injuries. Discrete aneurysms of 2 coronary artery branches and the pulmonary outflow tract were identified by cardiac catheterization. This patient was treated nonoperatively. CONCLUSIONS: Cardiac and great vessel injury after blunt trauma are uncommon in children. Cardiac contusion was the most common injury encountered but had minimal clinical significance. Noncontusion cardiac injury is rare. No patient with aortic transection was identified.

Analysis of pediatric head injury from falls.

The authors conducted a study to describe the incidence and types of fall-related head injury observed at a pediatric trauma center. We performed a retrospective analysis of all patients under 15 years of age treated for fall-related trauma between 1992 and 1998. Falls were classified as low (< 15 feet) and high level (> or = 15 feet). Seven hundred twenty-nine cases were identified with a mortality rate of 1.7%. A fall of greater than 15 feet (high-level fall) was associated with a higher mortality rate than low-level falls (2.4% compared with 1.0%, respectively). Ninety-eight patients had sustained a calvarial fracture and 93 experienced a basal skull fracture. Twenty-six patients had suffered a cerebral contusion, 25 a subarachnoid hemorrhage, 22 a subdural hematoma, and 12 had an epidural hematoma. Forty-nine patients required surgery for traumatic injuries; of these, 10 underwent craniotomy for evacuation of a blood clot. Height was not predictive of the Glasgow Coma Scale (GCS) score. In all four deaths resulting from a low-level fall there was an admission GCS score of 3, and abnormal findings were demonstrated on computerized tomography scanning. Death from high-level falls was attributable to either intracranial injuries (50%) or severe extracranial injuries (50%). Intracranial injury is the major source of fall-related death in children and, unlike extracranial insults, brain injuries are sustained with equal frequency from low- and high-level falls in this population. The only cause of mortality from low-level falls was intracranial injury. Trauma triage criteria must account for these differences in the pediatric population.

Efficacy of deferoxamine in preventing complications of iron overload in patients with thalassemia major.

BACKGROUND: To determine whether deferoxamine prevents the complications of transfusional iron overload in thalassemia major, we evaluated 59 patients (30 were female and 29 male; age range, 7 to 31 years) periodically for 4 to 10 years or until death. METHODS: At each follow-up visit, we performed a detailed clinical and laboratory evaluation and measured hepatic iron stores with a noninvasive magnetic device. RESULTS: The body iron burden as assessed by magnetic measurement of hepatic iron stores was closely correlated (R = 0.89, P < 0.001) with the ratio of cumulative transfusional iron load to cumulative deferoxamine use (expressed in millimoles of iron per kilogram of body weight, in relation to grams of deferoxamine per kilogram, transformed into the natural logarithm). Each increase of one unit in the natural logarithm of the ratio (transfusional iron load to deferoxamine use) was associated with an increased risk of impaired glucose tolerance (relative risk, 19.3; 95 percent confidence interval, 4.8 to 77.4), diabetes mellitus (relative risk, 9.2; 95 percent confidence interval, 1.8 to 47.7), cardiac disease (relative risk, 9.9; 95 percent confidence interval, 1.9 to 51.2), and death (relative risk, 12.6; 95 percent confidence interval, 2.4 to 65.4). All nine deaths during the study occurred among the 23 patients who had begun chelation therapy later and used less deferoxamine in relation to their transfusional iron load (P < 0.001). CONCLUSIONS: The early use of deferoxamine in an amount proportional to the transfusional iron load reduces the body iron burden and helps protect against diabetes mellitus, cardiac disease, and early death in patients with thalassemia major.

Hepatic iron stores and plasma ferritin concentration in patients with sickle cell anemia and thalassemia major.

To examine the relationship between hepatic iron stores and plasma ferritin concentration in individuals treated with red cell transfusion and iron chelation therapy, 37 patients with sickle cell anemia and 74 patients with thalassemia major were studied. In each patient, hepatic iron stores were measured by an independently validated noninvasive magnetic method, and plasma ferritin was determined by immunoassay. The correlation between hepatic iron and plasma ferritin was significant both in patients with sickle cell anemia (R = 0.75, P < 0.0001) and in those with thalassemia major (R = 0.76, P < 0.0001). Regression analysis showed no significant difference between the two groups in the linear relationships between hepatic iron stores and plasma ferritin. Considering all 111 transfused patients as a group, the coefficient of correlation between hepatic iron stores and plasma ferritin was highly significant (R = 0.76, P < 0.0001). Regression analysis found that variation in body iron stores, as assessed by magnetic determinations of hepatic iron, accounted for only approximately 57% of the variation in plasma ferritin, suggesting that the remainder was the result of other factors, such as hemolysis, ineffective erythropoiesis, ascorbate deficiency, inflammation, and liver disease. The 95% prediction intervals for hepatic iron concentration, given the plasma ferritin, were so broad as to make a single determination of plasma ferritin an unreliable predictor of body iron stores. Variability resulting from factors other than iron status limits the clinical usefulness of the plasma ferritin concentration as a predictor of body iron stores.
