Use of High-fidelity simulation training for radiology healthcare professionals in the management of acute medical emergencies

Objectives:Life-threatening emergencies are relatively uncommon in the radiology department, but when encountered, require timely intervention. With an increasing number of critically unwell patients visiting the radiology department each year for both diagnostic and interventional procedures, it is vital that radiology staff are trained to provide basic resuscitation before further assistance arrives. Simulation training is a well-validated, effective method for rehearsing low-frequency, high-acuity events in a supportive and safe environment. The aim of our study was to investigate whether the introduction of a focussed, multidisciplinary simulation course would improve healthcare professional’s knowledge and confidence when managing common medical emergencies; including cardiac arrest, anaphylaxis and airway obstruction.Methods:A multidisciplinary group of radiology staff attended a dedicated simulation teaching course. Participants completed a pre- and post-test questionnaire which assessed a range of knowledge domains and their perceived confidence with dealing with the clinical scenarios. The delegates were then asked to repeat this questionnaire 6 months after taking part in the course to assess their retention of skills and knowledge.Results:Knowledge scores increased by a mean difference of 4 points (p < 0.001). The mean pre- and post-course perceived confidence scores were 4.4/10 and 8/10, respectively.Advances in knowledge:This study suggests that embedding simulation training into the radiology curriculum improves healthcare professional’s knowledge and perceived confidence when dealing with common medical emergencies. Although previous studies have looked at the use of simulation training for radiology trainees in the management of selected medical emergencies, to the authors’ knowledge, this is the first study to demonstrate these benefits across a range of clinical scenarios, within an interprofessional environment.     

Inflight medical emergencies

This report responds to resolutions asking the American Medical Association (AMA) to develop recommendations for the use of medical equipment and technology onboard commercial airlines. Information for the report was derived from a search of the MEDLINE database and references listed in pertinent articles, as well as through communications with experts in aerospace and emergency medicine. Based on this information, the AMA Council on Scientific Affairs determined that, while inflight morbidity and mortality are uncommon, serious events do occur, which require immediate emergency care. Management of serious problems requires an integrated emergency response system that ensures rapid notification of medical personnel on the ground, assistance from appropriately trained flight crews and passenger volunteers (if available), and adequate medical supplies and equipment to stabilize the victim. Physicians have an important role in the preflight evaluation and counseling of potential passengers who are at risk of inflight medical complications, and in providing inflight medical assistance. Some U.S. and foreign air carriers are upgrading inflight emergency medical kits and placing automated external defibrillators aboard aircraft. Few data are available regarding the effectiveness of such improvements in improving health or survival outcomes. Recent federal legislation requires assessment of the extent of inflight medical emergencies, including the adequacy of emergency medical supplies and equipment carried onboard commercial airliners. This legislation also should alleviate liability concerns by providing immunity for physicians and others who render inflight medical assistance.     

Air medical transport of suspected aortic emergencies

PURPOSE: To review and characterize 4 years of experience with suggested nontraumatic aortic emergencies (dissections/ruptures) transported by a new, provincially dedicated rotor-wing air medical program METHODS: Retrospective 4-year review of air medical program's mission records and review of related hospital records. Patients listed as suspected aortic emergencies (nontraumatic) in the air medical records were included. Mission records were reviewed for EMS diagnosis, blood pressures before and after transport, transport times, and mortality. Hospital records were reviewed for diagnosis, interventions/treatment, and mortality. Blood pressures below 80 mmHg systolic were considered hemodynamically unstable. RESULTS: A cohort of 34 patients were identified, of whom 31 (91%) arrived at the hospital alive. Twenty-five patients (74%) arrived hemodynamically stable, with a mean out-of-hospital time of 60 minutes, and nine patients (26%) were hemodynamically unstable (mean out-of-hospital time was 54 minutes). No significant difference arose in times between these two groups (P = 0.16). Overall mortality was 53% (18). Differences in transport time between survivors and deaths was not statistically significant (P = 0.93). The diagnoses on admission to hospital: 14 (41%) were RAAA, five (15%) AAA no rupture, eight (24%) aortic dissections, and four (12%) had no aortic pathology. Seventeen patients (50%) received emergent surgical intervention. The EMS diagnosis was correct in 76% of cases. CONCLUSION: Our program transported 34 suspected aortic emergencies of which 17 were immediate surgical candidates on arrival. Aortic emergencies are not infrequent within our program. Specific policies and procedures based on continuing quality review should be in place to optimize the transport and care of these patients.     

Immediate management of injuries.

Specific injuries are not confined to any particular sport, but regular injury patterns will occur among the players of any given sport. Emphasis is placed on the need for primary treatment facilities, the experience of the attendant, and the importance of a working knowledge of the sport involved. Diagnostic difficulties are described with reference to cervical oral, ocular and other injuries. Immediate and long-term management of injuries to the lower limbs is considered.     

Abdominal vascular emergencies: US and CT assessment

Acute vascular emergencies can arise from direct traumatic injury to the vessel or be spontaneous (non-traumatic).The vascular injuries can also be divided into two categories: arteial injury and venous injury.Most of them are life-treatening emergencies, sice they may cause an important ipovolemic shock or severe ischemia in their end organ and require prompt diagnosis and treatment.In the different clinical scenarios, the correct diagnostic approach to vascular injuries isn’t firmly established and advantages of one imaging technique over the other are not obvious.Ultrasound (US) is an easy accessible, safe and non-invasive diagnostic modality but Computed Tomography (CT) with multiphasic imaging study is an accurate modality to evaluate the abdominal vascular injuries therefore can be considered the primary imaging modality in vascular emergencies.The aim of this review article is to illustrate the different imaging options for the diagnosis of abdominal vascular emergencies, including traumatic and non traumatic vessel injuries, focusing of US and CT modalities.     

Association of splenic and renal infarctions in acute abdominal emergencies

INTRODUCTION: Splenic and renal infarctions are usually related to vascular disease or haematologic abnormalities. Their association is infrequent and rarely observed in trauma. In this study, we analyze our data to look at the occurrence of renal and splenic infarctions based on CT findings in a period of 4 years. MATERIALS AND METHODS: We retrospectively reviewed the imaging findings of 84 patients admitted to our Department of Diagnostic Imaging from June 1998 to December 2002, who underwent emergency abdominal spiral CT examination and in whom there was evidence of splenic and/or renal infarction. RESULTS: We found 40 cases of splenic infarction and 54 cases of renal infarction, associated in 10 patients. In 26 patients, there was also evidence of intestinal infarction. A traumatic origin was found in 19 cases; non-traumatic causes were found in 65 patients. Association between renal and splenic infarction in the same patient was related to trauma in two cases. CONCLUSIONS: Although renal and splenic infarctions are a common manifestation of cardiac thromboembolism, other systemic pathologies, infections or trauma may lead to this occurrence. Renal infarction may be clinically and/or surgically managed with success in most cases. There are potential complications in splenic infarction, such as development of pseudocysts, abscesses, hemorrhage, subcapsular haematoma or splenic rupture; splenectomy in these cases may be necessary. Some patients with splenic and/or renal infarction may be clinically asymptomatic. The high accuracy of CT examination is needed to allow a correct evaluation of infarcted organs.     

Ultrasound evaluation of acute abdominal emergencies in infants and children

Ultrasound is extremely beneficial in the evaluation of acute pediatric abdominal disease, such as HPS, intussusception, and acute appendicitis. As techniques and equipment improve, its role in the evaluation of infants and children continues to increase.     

Response capability during civil air carrier inflight medical emergencies

Expanded civil aircraft medical emergency kits have been mandated on U.S. carriers since August 1986. Airlines provided the Federal Aviation Agency reports on medical kit usage and outcomes of the associated medical emergencies; 1,016 inflight medical events during the period August 1, 1986, through July 31, 1987, were available for review. Physicians responded to the emergencies in over 63% of the occurrences; the two most prevalent presenting situations were chest pain and syncopal episodes. Nine passengers died on board aircraft, and at least three deaths occurred postlanding. A minimum of 89 of the total cases resulted in flight diversions. The sphygmomanometer (739 cases) and stethoscope (734 cases) were the most frequently used kit items; oropharyngeal airways were utilized in 14 cases. Since standardized reporting formats are not required, evaluation of response capability remains incomplete.

Imaging of acute gastric emergencies: a case-based review

The stomach is one of the most frequently imaged organs in the body with dedicated and incidental inclusion in chest imaging modalities. Gastric emergencies often present clinically with non-specific abdominal, nausea, and vomiting. As such, imaging plays a critical role in early identification and treatment of a myriad of gastric emergencies. The goal of this paper is to showcase gastric emergencies as they appear on multimodality imaging.
