Background: The rate of trauma in the elderly is growing.

Objectives: To evaluate the characteristics of non-hip fracture-associated trauma in elderly patients at a level I trauma center.

Methods: The study database of this retrospective cohort study was the trauma registry of a level I trauma center. Trauma patients admitted from January 2001 to December 2003 were stratified into different age groups. Patients with the diagnosis of hip fracture were excluded.

Results: The study group comprised 7629 patients. The non-hip fracture elderly group consisted of 1067 patients, 63.3% women and 36.7% men. The predominant mechanism of injury was falls (70.5%) and most of the injuries were blunt (94.1%). Injury Severity Score was found to increase significantly with age. The average mortality rate among the elderly was 6.1%. Age, ISS[1], Glasgow Coma Score on admission, and systolic blood pressure on admission were found to be independent predictors of mortality.

Conclusions: Falls remain the predominant cause of injury in the elderly. Since risk factors for mortality can be identified, an effective community prevention program can help combat the future expected increase in morbidity and mortality associated with trauma in the elderly.

Background: Intramural duodenal hematoma generates partial or complete obstruction that develops slowly and progressively with a consequent delay in diagnosis. Many diagnostic and therapeutic measures remain debatable and justify a review of current management policy.

Objectives: To highlight the diagnostic and therapeutic steps in pediatric IDH[1].

Methods: The records of 12 children with post-traumatic IDH who were treated in the Hillel Yaffe Medical Center between 1986 and 2000 were retrospectively reviewed. Three of them had clotting disorders and were excluded. The interval between their admission and diagnosis as well as the therapeutic decisions were evaluated and analyzed.

Results: Nine children were treated for IDH. The interval between admission and diagnosis ranged from 24 hours to 6 days. Five children had associated traumatic pancreatitis. Initially, all the children were conservatively treated. In seven the hematoma resolved after 9–20 days. Two children were operated upon because the obstruction failed to resolve. All nine children recovered without permanent complications.

Conclusions: Intramural duodenal hematoma has many clinical and therapeutic puzzling aspects. Bicycle handlebar, road accidents and sports trauma are the main etiologic factors in children, but child abuse should be kept in mind. Associated traumatic pancreatitis is common. Gastroduodenal endoscopy may be useful to clarify doubtful cases. Pediatric surgeons should increase awareness regarding IDH in order to reduce delay in diagnosis and the need for surgical decompression.

Background: The contribution of drugs and alcohol to current trauma‑related morbidity and mortality in Israel is not known. Identification of these factors in the fast-changing demographics of the Israeli population might lead to better care and, no less importantly, to targeted prevention measures.

Objectives: To determine the incidence of alcohol‑related trauma, and to specify the time of day, the cause of trauma, and the morbidity and mortality rates as compared to non-alcohol‑associated trauma in the tertiary trauma unit of a large medical center in Tel Aviv.

Methods: Data were obtained from the Israel National Trauma Registry, based on patient records in our institution (Tel Aviv Sourasky Medical Center) from January 2001 to December 2003.

Results: Of the 5,529 patients who were enrolled in the study, 170 had high alcohol blood levels (> 50 mg/dl). Patients intoxicated with alcohol had higher rates of road accident injuries (35% versus 24% non‑intoxicated) and stab wounds (29% vs. 7%). The Injury Severity Score of the alcohol‑intoxicated patients was higher (32% ³ 16 vs. 12% ³ 16). The alcohol‑intoxicated patients were more likely to be non-Jewish (34% vs. 9%), young (82% aged 15–44 years) and males (91%). Most of the alcohol‑related injuries occurred during the weekend (47%) and during evening‑late night hours (from 7 a.m. to 11 p.m.; 55%).

Conclusions: Alcohol‑associated trauma differs from non-alcohol‑associated trauma in many ways. Since the population at risk can be identified, it is important that legislative, social, enforcement and educational measures be adopted to reduce the extent of alcohol abuse and thereby improve the level of public safety.
 

The care of the trauma victim can be divided into five to six phases, none of which can be bypassed.

Three decades have elapsed since the inception of Level I trauma centers as the final link in the trauma system "chain of survival".

The first Trauma Unit in Israel was founded at the Hadassah (Ein Kerem) Medical Center in 1992 - the result of increased awareness to the new concept of optimal care for the injured patient.

Background: In Japan, helicopters have rarely been used for emergency medical services. The use of helicopters not only ensures rapid evacuation but may also serve to provide emergency management to patients with life-threatening injuries in the prehospital setting.

Objectives: To evaluate a Japanese helicopter-based emergency medical system including an onboard physician, particularly in terms of probability of survival.

Methods: We conducted a retrospective review of trauma victims, and calculated two estimates of PS[1] – at the scene and on arrival at the emergency department – based on patient age, Injury Severity Score, and Revised Trauma Score.

Results: We identified trauma victims who had an ISS[2] above 15 and were transported from the scene by helicopter. Excluding cardiopulmonary arrest at the scene, 151 cases were studied. Thirty-two patients had hemodynamic instability with systolic blood pressures below 90 mmHg, caused by hemorrhagic shock (29 cases) or obstructive shock (3 cases). Their PS values were 0.56 ± 0.38 in the prehospital setting and 0.65 ± 0.38 on arrival at the ED[3], representing a significant difference (P = 0.0003). Twenty-four of these patients survived, reflecting successful resuscitation during prehospital and ED management.

Conclusions: A doctor-helicopter system was shown to improve probability of survival for life-threatening trauma in the Japanese emergency medical system.

"Surviving severe injury depends very heavily upon the time it takes to receive trauma services. The risk of death increases three fold after one hour without the uniqe surgical care of a trauma center. This is often referred to as the 'golden hour'..."

Objectives: To use pelvic fractures as a test case for the efficiency of the Israeli trauma system, as reflected in the experience of our medical center.

Methods: Data were obtained from the medical charts of all cases of pelvic fractures admitted to our medical center between 1987 and 1999. We obtained demographic data, information on the cause of injury, fracture classification, co-injuries and Injury Severity Score, treatment strategies, and mortality rate.

Results: Altogether, 808 patients with pelvic injuries were treated in our medical center. The most common cause of injury was motor vehicle accidents (51%). Pelvic fractures without acetabular involvement were diagnosed in 58% of patients and isolated acetabular fractures in 32%, while 10% sustained combined injuries to the pelvic ring and the acetabulum. The overall rate of operative stabilization was 34%. The majority of patients had associated injuries, mostly additional musculoskeletal injuries. Altogether, 13% were referred from Level II/III trauma centers. We observed an increase in the total number of local admissions, in the percentage of referred patients and in the percentage of operated patients during the study period. The observed mortality rate was 5%.

Conclusions: Our results show a more than twofold increase in the percentage of referred patients following the designation of a Level I trauma center. These referrals result not only from the designation as a Level I trauma center, but also from the presence of a dedicated team of pelvic fracture specialists, available 24 hours a day. In addition, a larger percentage of patients undergo surgery for internal fixation of pelvic fractures, in accordance with current worldwide trends.

Objectives: To report our experience in the treatment of pelvic fractures.

Methods: Between October 1998 and September 2001, 78 patients with pelvic fractures were admitted to our hospital. The age range of the 56 male and 22 female patients was 16–92 (mean 42 years). The cause of injury was road accident in 52 patients, fall from a height in 15, a simple fall in 9, and gunshot wounds in 2 patients. The Glascow Coma Scale score on arrival at the hospital was 3–15 (average 12). Twenty-five patients (32%) were admitted to the intensive care unit, 38 (48%) to the orthopedic department, 5 (6.4%) to neurosurgery and the remainder to a surgical department.

Results: Twenty-six patients (33.3%) received blood transfusion in the first 24 hours. Of the 25 patients (32%) with associated head trauma, 6 had intracranial bleeding; 29 patients (37%) had associated chest trauma, 28 (35.9%) had associated abdominal trauma, 16 (20.5%) had vertebral fractures and 40 (51.2%) had associated limb fractures. Pelvic angiography was performed in 5 patients (6.4%), and computed tomography-angiography of the cervical arteries and chest was performed in 1 and 5 patients respectively. Overall, a CT scan was performed in 56 patients (71.8%), of whom 25 (32%) had a pelvic CT on admission. Injury Severity Score was 4–66 (median 20). Laparotomy was performed in 14 patients (18%), spinal fusion in 5 (6.4%), limb surgery in 16 (20.5%), cranial surgery in 4 (5.02%), pelvic surgery in 10 (12.8%), chest surgery in 3 (3.85%), and facial surgery in 2 patients (2.56%). Seven patients (9%) died during the course of treatment.

Conclusion: Pelvic fracture carries a high morbidity rate. Associated chest, abdomen and limb injuries are often encountered. A multidisciplinary approach is needed to improve survival and outcome in patients with pelvic fractures. 

Objectives: To provide data on fatal traumatic heart wounds in autopsied cases.

Methods: We reviewed 2,487 medico-legal autopsy records of the morgue department of the Bursa branch of the Turkish Council of Forensic Medicine for the period 1997–2001.

Results: Of these cases, 160 (6.4%) had cardiac injury; 13.8% were females and 86.2% males, and the mean age was 35.9 years old (range 4–65). The most common cause of heart wounds was penetrating trauma (87.5%), namely sharp injuries (48.1%) and firearm injuries (39.4%). The two most common causes of blunt heart wounds were traffic accidents (5.6%) and falls from a height (5%). Rupture was present in 96.9% of the cases, and isolated left ventricle and isolated right ventricle were ruptured in 31.3% and 23.8%, respectively. In penetrating injury the risk of ventricle rupture was higher than of atrium rupture. Alcohol was detected in 16.3% of cases. Only 3.5% of the penetrating cardiac injury cases and 5% of the blunt cardiac injury cases were admitted to hospital.

Conclusions: Given that only a very low percentage of the patients who sustain cardiac injury reach hospital alive, population-based studies, especially autopsy results, should be conducted to define the characteristics of cardiac injuries.

Background: The proportion of motorcyclists injured in road accidents in Israel is larger than their proportion among road users.

Objectives: To identify factors contributing to the risk of injury for motorcyclists as compared to drivers of other motor vehicles.

Methods: We retrieved and analyzed National Trauma Registry data on drivers, aged 16 and above, who were involved in traffic accidents and hospitalized between 1 January 1997 and 30 June 2003.

Results: The study group comprised 10,967 patients: 3,055 (28%) were motorcyclists and 7,912 (72%) were drivers of other motor vehicles. A multiple logistic regression revealed that Tel Aviv, the busiest metropolitan city in Israel, is a risk for motorcycle injury as compared to other regions; males have an increased risk compared to females; and age is a protecting factor since the risk of injury as a motorcyclist decreases as age increases. Nevertheless, the population of injured motorcyclists in Tel Aviv was significantly older (mean age 32.5 years vs. 28.6 elsewhere; t-test P < 0.0001). Twenty percent (n=156) of the injured motorcyclists in Tel Aviv were injured while working, compared to 9.5% (n=217) in other regions (chi-square P < 0.0001). Motorcycle injuries in Tel Aviv were of lower severity (7.7% vs. 16.4% according to the Injury Severity Scale 16+, c2 P < 0.0001), and had lower inpatient death rates (1.2% vs. 2.5%, c2 P = 0.001).

Conclusions: Tel Aviv is a risk for motorcycle injury compared to other regions, males have an increased risk compared to females, and age is a protecting factor. The proportion of motorcyclists in Tel Aviv injured while working is double that in other regions
