Effect of teleradiology upon pattern of transfer of head injured patients from a rural general hospital to a neurosurgical referral centre.

Objective: To assess the effect of teleradiology upon the need for transfer of head injured victims requiring hospitalisation but referred initially to a rural level 2 trauma centre without neurosurgical capacity. Methods: Head injured patients requiring hospitalisation, admitted to a rural level 2 trauma centre between August 2003 and August 2005, were identified. A digitalised copy of the computed tomographic (CT) scan was transferred to the neurosurgical referral centre via teleradiology and was available for review by the neurosurgeon on-call, who then, together with the trauma surgeon in the rural level 2 trauma centre, decided whether to transfer the patient to the neurosurgical referral centre. Results: Of 209 trauma victims with neurosurgical pathology in need of hospitalisation, 126 (60.2%) were immediately transferred while 83 (39.7%) of the patients were hospitalised in the rural level 2 trauma centre for observation. Two (2.4%) failed the intent to treat locally. One patient, suffering from multi-trauma, was stabilised after damage control laparotomy only to succumb to an enlarging epidural haematoma. Another patient was transferred 2 days after admission because of difficulty in clinical evaluation due to a previously existing neurological disorder, but no active treatment was necessary. All other 81 patients recovered uneventfully. Conclusions: Selective head injured patients with pathological CT scan may be safely managed in level 2 trauma centres. A committed trauma team in the rural trauma centre, neurosurgical consultation and availability of a teleradiology system are requisites. Currently existing transfer criteria should be carefully re-evaluated.

Prehospital management of earthquake casualties buried under rubble.

Earthquakes continue to exact a heavy toll on life, injury, and loss of property. Survival of casualties extricated from under the rubble depends upon early medical interventions by emergency teams on site. The objective of this paper is to review the pertinent literature and to analyze the information as a practical guideline for the medical management of casualties accidentally buried alive.

Precision of In-Hospital Triage in Mass-Casualty Incidents after Terror Attacks

INTRODUCTION Proper management of mass-casualty incidents (MCIs) relies on triage as a critical component of the disaster plan. OBJECTIVE [corrected] The objective of this study was to assess the precision of triage in mass-casualty incidents. METHODS The precision of decisions made by two experienced triage officers was examined in two large MCIs. These decisions were compared to the real severity of injury as defined by the Israeli Defence Forces (IDF) classification of severity of injuries and the Injury Severity Score (ISS). RESULTS Two experienced trauma physicians triaged a total of 94 casualties into 77 mild, seven moderate, and 10 severe casualties. Based on the IDF criteria, there were 74 mild, five moderate, and 15 severe casualties. Based on ISS scoring, there were 78 mild (ISS <9), five moderate (9 < or = ISS < 16), and 11 severe (ISS <16) casualties. Of 15 severely injured victims defined by the IDF classification of injury severity, the triage officers identified only seven (47%). CONCLUSION Primary triage, even when carried out by experienced trauma physicians, can be unreliable in a MCI.

Selection of patients with severe pelvic fracture for early angiography remains controversial

BackgroundPatients with severe pelvic fractures represent about 3% of all skeletal fractures. Hemodynamic compromise in unstable pelvic fractures is associated with arterial hemorrhage in less than 20% of patients. Angiography is an important tool in the management of severe pelvic injury, but indications and timing for its performance remain controversial.MethodsPatients with major pelvic fractures [Pelvic Abbreviated Injury Score (AIS) ≥ 3] admitted to two high volume Trauma Centers from January 2000 to June 2005 were identified and divided into two groups: Group I patients did not undergo angiography, Group II patients underwent angiography with/without embolization. Demographics, hemodynamic status on admission, concomitant injuries, Glasgow Coma Scale (GCS), Injury Severity Score (ISS), pelvic AIS, blood requirement before and after angiography, arterial blood gases and mortality were evaluated. Patients with an additional reason for hemodynamic instability were excluded.ResultsCharts of 106 patients were retrospectively reviewed. Twenty nine patients (27.4%) underwent angiography. Bleeding vessel embolization was performed in 20 (18.9%) patients. Patients who underwent angiography had a significantly higher pelvic AIS and a lower Base Excess level on admission. A blood transfusion rate of greater than 0.5 unit/hour was found to be a reliable indicator for early angiography.ConclusionA high pelvic AIS, amount of blood transfusions and decreased BE level should be considered as an indicators for early angiography in patients with severe pelvic injury.

Concomitant hollow viscus injuries in patients with blunt hepatic and splenic injuries: an analysis of a National Trauma Registry database.

INTRODUCTION Non-operative management has become the standard approach for treating stable patients sustaining blunt hepatic or splenic injuries in the absence of other indications for laparotomy. The liberal use of computed tomography (CT) has reduced the rate of unnecessary immediate laparotomies; however, due to its limited sensitivity in the diagnosis of hollow viscus injuries (HVI), this may be at the expense of a rise in the incidence of missed HVI. The aim of this study was to assess the incidence of concomitant HVI in blunt trauma patients diagnosed with hepatic and/or splenic injuries, and to evaluate whether a correlation exists between this incidence and the severity of hepatic or splenic injuries. METHODS A retrospective cohort study involving blunt trauma patients with splenic and/or liver injuries, between the years 1998 and 2012 registered in the Israel National Trauma Registry. The association between the presence and severity of splenic and/or liver injuries and the incidence of HVI was examined. RESULTS Of the 57,130 trauma victims identified as suffering from blunt torso injuries, 2335 (4%) sustained hepatic injuries without splenic injuries (H group), 3127 (5.4%) had splenic injuries without hepatic injuries (S group), and 564 (1%) suffered from both hepatic and splenic injuries (H+S group). Overall, 957 patients sustained 1063 HVI. The incidence of HVI among blunt torso trauma victims who sustained neither splenic nor hepatic injuries was 1.5% which is significantly lower than in the S (3.1%), H (3.1%), and H+S (6.7%) groups. In the S group, there was a clear correlation between the severity of the splenic injury and the incidence of HVI. This correlation was not found in the H group. CONCLUSIONS The presence of blunt splenic and/or hepatic injuries predicts a higher incidence of HVI, especially if combined. While in blunt splenic injury patients there is a clear correlation between the incidence of HVI and the severity of splenic injury, such a correlation does not exist in patients with blunt hepatic injury.

Management of Victims in a Mass Casualty Incident Caused by a Terrorist Bombing: Treatment Algorithms for Stable, Unstable, and In Extremis Victims

Bombs aimed at civilian populations are the most common weapon used by terrorists throughout the world. Over the last decade, we have been involved in the management of more than 20 mass casualty incidents, most of which were caused by terrorist bombings. Commonly, in these events, there may be many victims and many deaths. However, only a few of the survivors will suffer from life-threatening injuries. Appropriate and timely treatment may impact their survival. Due to the complex mechanism of injury seen in these scenarios, treatment of victims injured by explosions is somewhat different from that exercised in blunt and penetrating trauma from other causes. The intention of this article was to outline the initial medical treatment of the injured victim arriving at the emergency department during a mass casualty incident caused by a terrorist bombing. Treatment protocols for stable, unstable, and in extremis patients are presented.

Rib fractures: comparison of associated injuries between pediatric and adult population

BACKGROUND Rib fractures are considered a marker of exposure to significant traumatic energy. In children, because of high elasticity of the chest wall, higher energy levels are necessary for ribs to fracture. The purpose of this study was to analyze patterns of associated injuries in children as compared with adults, all of whom presented with rib fractures. METHODS A retrospective cohort study involving blunt trauma patients with rib fractures registered in the National Trauma Registry was conducted. RESULTS Of 6,995 trauma victims who were found to suffer from rib fractures, 328 were children and 6,627 were adults. Isolated rib fractures without associated injuries occurred in 19 children (5.8%) and 731 adults (11%). More adults had 4 or more fractured ribs compared with children (P < .001). Children suffered from higher rates of associated brain injuries (P = .003), hemothorax/pneumothorax (P = .006), spleen, and liver injury (P < .001). Mortality rate was 5% in both groups. CONCLUSIONS The incidence of associated head, thoracic, and abdominal solid organ injuries in children was significantly higher than in adults suffering from rib fractures. In spite of a higher Injury Severity Score and incidence of associated injuries, mortality rate was similar. Mortality of rib fracture patients was mostly affected by the presence of extrathoracic injuries.

Burkitt's Lymphoma: An Unusual Cause of Obstructive Jaundice

Biliary obstruction secondary to malignancy is a common clinical problem. Rarely, biliary obstruction is due to non-Hodgkins lymphoma. Obstructive jaundice in these patients usually presents late in the course of the disease. Burkitts lymphoma is a subtype of non-Hodgkins lymphoma. Unlike other forms of non-Hodgkins lymphoma, Burkitts lymphoma presents as an extranodal disease. We present the case of a patient suffering from non-endemic Burkitts lymphoma whose initial presenting symptom was obstructive jaundice.

New Technique of Direct Intra-abdominal Pressure Measurement

OBJECTIVE To determine the efficacy of 14-Fr PVC round drain in the direct measurement of intra-abdominal pressure. METHODS Fifty consecutive patients undergoing elective laparoscopic surgery in a tertiary teaching hospital were included in this pilot study. Patients underwent laparoscopic cholecystectomy, appendectomy, splenectomy, colectomy and Nissen fundoplication. After creation of pneumoperitoneum and insertion of the trocars as indicated by the operation, a 14-Fr PVC round drain was inserted into the abdominal cavity via one of the laparoscopic ports. It was then connected under sterile conditions to the invasive blood pressure measurement system. Intra-abdominal pressure was gradually increased. Intra-abdominal pressures as measured through the round PVC drain were compared to those measured by the laparoscopic insufflator at 5, 8, 12 and 24 mmHg. RESULTS Two hundred measurements using each of the two methods were performed and correlated. The correlation coefficient was 0.996. No complications were observed with this new technique. CONCLUSION Direct measurement of intra-abdominal pressure using 14-Fr PVC round drain is a newly described technique that is simple, fast and credible. Future investigation will be needed to confirm the reliability of this method during postoperative follow-up of intra-abdominal pressures in selected patients.

Sternal Fracture Should Prompt the Evaluation of the Entire Spine in Trauma Patients

Background and Purpose:Sternal fracture has traditionally been considered an indicator of a severe mechanism of trauma, which warrants careful evaluation of the patient for accompanying injuries. The purpose of this study is to determine the incidence, distribution and mechanisms of spinal fractures associated with fractures of the sternum.Material and Methods:Trauma registry data, medical records and X-rays of all patients admitted to the Trauma Unit at Hillel-Yaffe Medical Center, Hadera, Israel, with a diagnosis of sternal fracture during a 6-year period, between January 1, 1997 and December 31, 2002, were reviewed retrospectively.Results:147 patients with sternal fracture were eligible for analysis. The combination of spinal fracture in association with sternal fracture was found in 19 patients (13%), ten males (52.7%) and nine females (47.3%). Mean age was 49 years and mean Injury Severity Score (ISS) 18.6. Motor vehicle accidents were the most common cause of these fractures. An unusually high proportion of cervical spine fractures (36.8%) was noted. Three of the 19 patients (15.5%) with sternal and spinal fractures also suffered from cardiac contusion, confirmed by an elevation of the MB fraction of creatine phosphokinase, ECG changes, and regional hypokinetic areas on echocardiography.Conclusion:Recent studies indicate that the incidence of sternal fracture has risen while its association with accompanying serious injuries has lessened. This is most likely due to the increased use of seat belts in motor vehicle accidents. In both theory and practice spinal fracture is an associated injury in cases of sternal fracture, and usually involves the thoracic level. The authors describe an almost equal distribution of the level of spinal injury, with an unusually high proportion of cervical involvement. They also found a high incidence of myocardial contusion among patients with combined sternal and spinal fractures. Therefore, X-ray evaluation of the entire spine in patients suffering from a fractured sternum, and closer cardiac monitoring of patients with both sternal and spinal fractures are recommended.
