The bussola study. Final results, conclusions and proposals

OBJECTIVE: To evaluate the use of thrombolytic and acetylsalicylic acid therapies in acute myocardial infarct patients as well as the availability of technical and human resources for the care of these patients in the emergency units of the city of Rio de Janeiro. Additional objectives were the evaluation of the use of primary angioplasty and the level of acceptance of SBC /RJ as an entity responsible for programs of continued medical education. METHODS: Interviews with physicians at 46 emergency units in the city of Rio de Janeiro. RESULTS: Of the 46 emergency units inspected, a policy of encouragement to use thrombolytic therapy was only prescribed in 6.5%. In 1/3 of the public wards no thrombolytic agents were available, and in none of them was access to primary angioplasty regularly available; 45.9% did not offer the minimal conditions required for the handling of cases of acute myocardial infarction; 60% of the physicians on-call (at both public and private emergency units), appeared not to know the importance of the use of acetylsalicylic acid in acute myocardial infarct patients; all physicians interviewed would participate in programs of continued medical education organized by the SBC/RJ. CONCLUSION: The study suggests there was: 1) the low probability of the use of thrombolytic therapy in the majority of the emergency units in of the city of Rio de Janeiro due to the inadequate policy of waiting for the transfer of the patient to coronary or intensive care unit; 2) a low awareness to the importance of early use of acetylsalic acid in acute myocardial infarct; 3) half of the emergency units of the public net do not have the minimal conditions required for the handling of cases of acute myocardial infarction; 4) a high level of credibility exists that would enable the SBC/RJ to set up programs for continued medical education to change the mentality regarding the use of thrombolytic therapy and of acetylsalicylic acid.

Stress During ACLS Courses: Is it Important for Learning Skills?

OBJECTIVE: To determine the influence of stress on teaching medical emergencies in an Advanced Cardiac Life Support (ACLS) course and to verify this influence on learning, and the efficiency of emergency care training. METHODS: Seventeen physicians signed up for an ACLS course. Their pulses were taken and blood pressure (BP) verified on the first day, before the beginning of the course, and on the second day, during the theoretical and practical test (TPT). Variations in pulse rates and BP were compared with students' test grades. Then, students answered a questionnaire of variables (QV) about the amount of sleep they had during the course, the quantity of study material and the time spent studying for the course, and a stress scale graphic. RESULTS: Seven students had a pulse variation less than 10% between the 2 periods and 10 had a 10% or more variation. Grades on TPT were, respectively, 91.4±2.4 and 87.3±5.2 (p<0.05). Six students had a BP variation less than 20 mmHg, and in 11 it varied more than 21 mmHg. Grades on the TPT were 92.3±3.3 and 86.2± 8.1, respectively (p<0.05). The QV dates did not significantly influence grades. CONCLUSION: Stress, as an isolated variable, had a negative influence on the learning process and on the efficiency of emergency training in this situation.

Impact of duration of chest tube drainage on pain after cardiac surgery.

OBJECTIVE: This study was designed to analyze the duration of chest tube drainage on pain intensity and distribution after cardiac surgery. METHODS: Two groups of 80 cardiac surgery adult patients, operated on in two different hospitals, by the same group of cardiac surgeons, and with similar postoperative strategies, were compared. However, in one hospital (long drainage group), a conservative policy was adopted with the removal the chest tubes by postoperative day (POD) 2 or 3, while in the second hospital (short drainage group), all the drains were usually removed on POD 1. RESULTS: There was a trend toward less pain in the short drainage group, with a statistically significant difference on POD 2 (P=0.047). There were less patients without pain on POD 3 in the long drainage group (P=0. 01). The areas corresponding to the tract of the pleural tube, namely the epigastric area, the left basis of the thorax, and the left shoulder were more often involved in the long drainage group. There were three pneumonias in each group and no patient required repeated drainage. CONCLUSIONS: A policy of early chest drain ablation limits pain sensation and simplifies nursing care, without increasing the need for repeated pleural puncture. Therefore, a policy of short drainage after cardiac surgery should be recommended.

Engorgement des centres d'urgences: une raison légitime de refuser l'accès aux patients non urgents [Emergency department overcrowding: a legitimate reason to refuse access to urgent care for non-urgent patients?].

Non-urgent cases represent 30-40% of all ED consults; they contribute to overcrowding of emergency departments (ED), which could be reduced if they were denied emergency care. However, no triage instrument has demonstrated a high enough degree of accuracy to safely rule out serious medical conditions: patients suffering from life-threatening emergencies have been inappropriately denied care. Insurance companies have instituted financial penalties to discourage the use of ED as a source of non-urgent care, but this practice mainly restricts access for the underprivileged. More recent data suggest that in fact most patients consult for appropriate urgent reasons, or have no alternate access to urgent care. The safe reduction of overcrowding requires a reform of the healthcare system based on patients' needs rather than access barriers.

Agents mòbils en situacions d'emergència: mobilitat d'etiquetes de triatge

En les actuacions de rescat en emergències amb un gran nombre de víctimes, una de les primeres tasques a realitzar pels serveis sanitaris és la de triar-les en funció del seu estat i la urgència amb que han de ser tractades. En el grup SeNDA es treballa en un sistema d’agents mòbils que automatitza el mecanisme manual de triatge, fent ús de dispositius electrònics i una xarxa MANET com a canal de comunicació. En aquest projecte es proposa un sistema de gestió de mobilitat pels agents que transporten dades de víctimes fins al centre de coordinació, juntament amb un mecanisme de control d’aquests agents totalment transparent a l’usuari.

Medical aspects of helicopter rescue missions involving winching of a physician

Introduction: Whereas the use of helicopters as a rapid means toreach victims and to bring them to a secure place is well-recognized,very few data are available about the value of winching physicians toprovide medical care for the victims directly on-site. We sought to studythe medical aspects of alpine helicopter rescue operations involving thewinching of an emergency physician to the victim.Methods: We retrospectively reviewed the medical reports of a singlehelicopter-based emergency medical service. Data from 1 January 2003to 31 December 2008 were analyzed. Cases with emergency callindicating that the victim was deceased were excluded. Data includedthe category (trauma or illnesses), and severity (NACA score) of theinjuries, along with the main medical procedures performed on site.Results: 9879 rescue missions were conducted between 1 January2003 and 31 December 2008. The 921 (9.3%) missions involvingwinching of the emergency physician were analysed. 840 (91%)patients suffered from trauma-related injuries. The cases of the 81 (9%)people presenting with medical emergencies were, when compared tothe trauma victims, significantly more severe according to the NACAindex (p <0.001). Overall, 246 (27%) patients had a severe injury orillness, namely, a potential or overt vital threat (NACA score between4-6, table 1). A total of 478 (52%) patients required administration ofmajor analgesics: fentanyl (443 patients; 48%), ketamine (42 patients;5%) or morphine (7 patients; 1%). The mean dose of fentanyl was 188micrograms (range 25-750, SD 127). Major medical interventions wereperformed 72 times on 39 (4%) patients (table 2).Conclusions: The severity of the patients' injuries or illnesses alongwith the high proportion of medical procedures performed directlyon-site validate emergency physician winching for advanced life supportprocedures and analgesia.

Surgery for ruptured thoracic and thoraco-abdominal aortic aneurysms.

OBJECTIVE: To assess the outcome of patients with ruptured descending thoracic and thoracoabdominal aortic aneurysms undergoing emergency repair, in comparison to elective surgery for chronic lesions. METHODS: A prospective study of 100 consecutive patients operated upon the descending aorta (1-8 segments) using proximal unloading and distal protection with partial cardiopulmonary bypass, heparin surface-coated perfusion equipment and low systemic heparinization (loading dose 100 IU/kg, activated coagulation time > 180 s), staged cross-clamping, sealed grafts and graft inclusion. RESULTS: Arteriosclerotic lesions were present in 53/100 patients (53%) for all, 30/53 (56%) for chronic, and 21/33 (63%) for ruptured, aneurysms (NS). Dissecting lesions were found in 38/100 patients (38%) for all, 20/53 (38%) for chronic, and 8/33 (24%) for ruptured aneurysms (NS). Preoperative hematocrit was 38 +/- 6% for all, 40 +/- 5% for chronic, and 33 +/- 5% for ruptured aneurysmal patients (P < 0.001 ruptured versus chronic). The extent of aortic repair (1-8 segments) was 3.3 +/- 1.6 for all, 3.5 +/- 1.5 for chronic, and 3.2 +/- 1.4 for ruptured, aneurysms (NS). Transdiaphragmatic repair was performed in 51/100 (51%) of all, 28/53 (53%) of chronic, and 17/33 (51%) of ruptured aneurysms (NS). Aortic cross-clamp time was 38 +/- 21 min for all, 39 +/- 24 min for chronic, and 38 +/- 17 min for ruptured, aneurysmal patients (NS). The amount of red cells washed and autotransfused was 2792 +/- 2239 ml in all, 3143 +/- 2531 ml in chronic, and 2074 +/- 1350 ml in ruptured, aneurysmal patients (P < 0.025). The amount of packed red cells required was 2181 +/- 1830 ml for all, 1736 +/- 1333 ml for chronic, and 2947 +/- 2395 ml for ruptured aneurysmal patients (P < 0.010). Thirty-day mortality was 9/100 (9%) for all, 3/53 (6%) for chronic, and 5/33 (15%) for ruptured aneurysmal patients (NS). Parapareses/plegias occurred in 9/100 (9%) of all, 6/53 (11%) of chronic, and 3/33 (9%) of ruptured, aneurysmal patients (NS). Stepwise regression analysis identified aortic cross-clamp time as a predictor of early mortality (P = 0.002) and parapareses and paraplegias (P = 0.001). Age (P = 0.001), extent of repair (P = 0.008) and preoperative hematocrit (P = 0.001) were predictors for homologous transfusion requirements. CONCLUSION: Emergency repair of ruptured descending thoracic and thoracoabdominal aortic aneurysms can be achieved with acceptable results.

Female asylum seekers with musculoskeletal pain: the importance of diagnosis and treatment of hypovitaminosis D.

BACKGROUND: Hypovitaminosis D is well known in different populations, but may be under diagnosed in certain populations. We aim to determine the first diagnosis considered, the duration and resolution of symptoms, and the predictors of response to treatment in female asylum seekers suffering from hypovitaminosis D. METHODS: Design: A pre- and post-intervention observational study. Setting: A network comprising an academic primary care centre and nurse practitioners. Participants: Consecutive records of 33 female asylum seekers with complaints compatible with osteomalacia and with hypovitaminosis D (serum 25-(OH) vitamin D < 21 nmol/l). Treatment intervention: The patients received either two doses of 300,000 IU intramuscular cholecalciferol as well as 800 IU of cholecalciferol with 1000 mg of calcium orally, or the oral treatment only. Main outcome measures: We recorded the first diagnosis made by the physicians before the correct diagnosis of hypovitaminosis D, the duration of symptoms before diagnosis, the responders and non-responders to treatment, the duration of symptoms after treatment, and the number of medical visits and analgesic drugs prescribed 6 months before and 6 months after diagnosis. Tests: Two-sample t-tests, chi-squared tests, and logistic regression analyses were performed. Analyses were performed using SPSS 10.0. RESULTS: Prior to the discovery of hypovitaminosis D, diagnoses related to somatisation were evoked in 30 patients (90.9%). The mean duration of symptoms before diagnosis was 2.53 years (SD 3.20). Twenty-two patients (66.7%) responded completely to treatment; the remaining patients were considered to be non-responders. After treatment was initiated, the responders' symptoms disappeared completely after 2.84 months. The mean number of emergency medical visits fell from 0.88 (SD 1.08) six months before diagnosis to 0.39 (SD 0.83) after (P = 0.027). The mean number of analgesic drugs that were prescribed also decreased from 1.67 (SD 1.5) to 0.85 (SD 1) (P = 0.001). CONCLUSION: Hypovitaminosis D in female asylum seekers may remain undiagnosed, with a prolonged duration of chronic symptoms. The potential pitfall is a diagnosis of somatisation. Treatment leads to a rapid resolution of symptoms, a reduction in the use of medical services, and the prescription of analgesic drugs in this vulnerable population.

Diphtheria remains a threat to health in the developing world: an overview

Changes in the epidemiology of diphtheria are occurring worldwide. A large proportion of adults in many industrialized and developing countries are now susceptible to diphtheria. Vaccine-induced immunity wanes over time unless periodic booster is given or exposure to toxigenic Corynebacterium diphtheriae occurs. Immunity gap in adults coupled with large numbers of susceptible children creates the potential for new extensive epidemics. Epidemic emergencies may not be long in coming in countries experiencing rapid industrialization or undergoing sociopolitical instability where many of the factors thought to be important in producing epidemic such as mass population movements and difficult hygienic and economic conditions are present. The continuous circulation of toxigenic C. diphtheriae emphasizes the need to be aware of epidemiological features, clinical signs, and symptoms of diphtheria in vaccine era so that cases can be promptly diagnosed and treated, and further public health measures can be taken to contain this serious disease. This overview focused on worldwide data obtained from diphtheria with particular emphasis to main factors leading to recent epidemics, new clinical forms of C. diphtheriae infections, expression of virulence factors, other than toxin production, control strategies, and laboratory diagnosis procedures.

On-pump beating heart coronary surgery for high risk patients requiring emergency multiple coronary artery bypass grafting.

BACKGROUND: Cardiopulmonary bypass (CPB) with aortic cross-clamping and cardioplegic arrest remains the method of choice for patients requiring standard myocardial revascularization. Therefore, very high-risk patients presenting with acute coronary syndrome, unstable angina, onset of cardiac decompensation and requiring emergency multiple myocardial revascularization, can have a poor outcome. The on-pump beating heart technique can reduce the mortality and the morbidity in such a selected group of patients and this report describes our clinical experience. METHODS: Out of 290 patients operated for CABG from January 2005 to January 2006, 25 (8.6%) selected high-risk patients suffering from life threatening coronary syndrome (mean age 69 +/- 7 years) and requiring emergency multiple myocardial revascularization, underwent on-pump beating heart surgery. The mean pre-operative left ventricle ejection fraction (LVEF) was 27 +/- 8%. The majority of them (88%) suffered of tri-vessel coronary disease and 6 (24%) had a left main stump disease. Nine patients (35%) were on severe cardiac failure and seven among them (28%) received a pre-operative intra-aortic balloon pump. The pre-operative EuroScore rate was equal or above 8 in 18 patients (73%). RESULTS: All patients underwent on-pump-beating heart coronary revascularization. The mean number of graft/patient was 2.9 +/- 0.6 and the internal mammary artery was used in 23 patients (92%). The mean CPB time was 84 +/- 19 minutes. Two patients died during the recovery stay in the intensive care unit, and there were no postoperative myocardial infarctions between the survivors. Eight patients suffered of transitorily renal failure and 1 patient developed a sternal wound infection. The mean hospital stay was 12 +/- 7 days. The follow-up was complete for all 23 patients survived at surgery and the mean follow-up time was 14 +/- 5 months. One patient died during the follow-up for cardiac arrest and 2 patients required an implantable cardiac defibrillator. One year after surgery they all had a standard trans-thoracic echocardiogram showing a mean LVEF rate of 36 +/- 11.8%. CONCLUSION: Standard on-pump arrested heart coronary surgery has higher mortality and morbidity in emergencies. The on-pump beating heart myocardial revascularization seems to be a valid alternative for the restricted and selected cohort of patients suffering from life threatening coronary syndrome and requiring multiple emergency CABG.

Continuidad De Cuidados y Comunicación interniveles entre equipos de emergencias sanitarias y Atención Primaria.

The gradual incorporation of the nurses to the extrahospital emergency teams give them a holistic aspect in the field of care. And this is not possible without addressing the possibility of continuity of care and communication with other levels of care. All efforts in this regard and made speeches themselves as nursing, "Refer" (Nic 8100) and "Exchange of information on health care" (Nic 7960), is the conceptual framework of this work, which objetives are to quantify and exposing the proceedings in this line taken by the nurses of emergency team.

Prescripción enfermera en el contexto de las urgencias y emergencia

The area of the urgencies and emergencies, assisted from all levels and care settings raises, if possible, patterns of work and ways that collaboration between professionals and teamwork make nurse prescription, often pharmacological, a legislative needs in response to increased scientific evidence and through internationally accepted performance algorithms. Enabling the nurse to act according to these concepts and beyond any "doubt and suspicion" of illegality. Taking a consensus necessary training and development and according to professional specialization and differentiation in this area and as arguments to remove any doubt still remains the subject without enclosing any sense and in many sectors.
