Disección de aorta secundario a trauma, manejo clínico en Hospital General / Aortic dissection secondary to trauma, clinical management in General Hospital

INTRODUCCIÓN. La disección de aorta es una patología poco frecuente, cuando se presenta, lo hace de una manera catastrófica manifestada por dolor torácico o lumbar intenso acompañado de compromiso hemodinámico agudo, un diagnóstico y tratamiento temprano suelen ser cruciales para evitar la muerte del paciente, así mismo, una disección de aorta puede ser secundario a un trauma torácico por desaceleración y se presenta en 1,5% a 2%, lo que induce sobre todo a un desgarro localizado en la región del istmo aórtico. CASO CLÍNICO. Paciente masculino de 35 años, con antecedente de accidente en vehículo motorizado que provocó un traumatismo cráneo encefálico moderado, hematoma epidural parietal derecho, con resolución quirúrgica hace 18 meses, se descartó lesiones a nivel de tórax con radiografía de tórax normal, además se realizó ecografía FAST en ventana perihepática, suprapúbica, periesplénica y subxi-foidea sin encontrar alteración. Acudió al servicio de emergencia por un cuadro de hemiparesia derecha más disartria de 4 horas de evolución, se realiza tomografía de cráneo sin encontrarse lesión, catalogándose como evento cerebrovascular isquémico con recuperación neurológica. Durante su estancia hospitalaria presenta un cuadro de disnea de grandes esfuerzos y tras realizar exámenes complementarios de control se llega a una conclusión de una cardiomegalia, por lo que es referido a consulta de cardiología donde se realiza ecocardiograma, en la cual se observa disección de aorta ascendente más aneurisma por lo que se decide su ingreso y se instaura tratamiento mediante medidas de soporte, con derivación a hospital de especialidades para cirugía cardiotorácica. CONCLUSIONES. La disección de aorta secundario a un traumatis-mo es poco frecuente, sin embargo, el diagnostico siempre debe estar presente en caso de trauma por desaceleración, ya que es vital para la supervivencia del paciente y su manejo oportuno.

INTRODUCTION. Aortic dissection is an infrequent pathology; when it occurs, it does so in a catastrophic manner manifested by intense thoracic or lumbar pain accompanied by acute he-modynamic compromise. Early diagnosis and treatment are usually crucial to avoid the patient's death; likewise, aortic dissection can be secondary to thoracic trauma due to deceleration and occurs in 1.5% to 2%, which mainly induces a localized tear in the region of the aortic isthmus. CLINICAL CASE. 35-year-old male patient, with a history of motor vehicle accident that caused a moderate head injury, right parietal epidural hematoma, with surgical resolution 18 months ago, chest injuries were ruled out with normal chest X-ray, and FAST ultrasound was performed in perihepatic, suprapubic, perisplenic and subxiphoid window without finding any alteration. She went to the emergency department for a picture of right hemiparesis and dysarthria of 4 hours of evolution, a cranial tomography was performed without finding any lesion, being clas-sified as an ischemic cerebrovascular event with neurological recovery. During his hospital stay he presented with dyspnea of great effort and after performing complementary control tests, a cardiomegaly was found, so he is referred to a cardiology clinic where an echocardiogram is per-formed, which showed dissection of the ascending aorta plus aneurysm, admission is decided and treatment is instituted through supportive measures, with referral to a specialty hospital for cardiothoracic surgery. CONCLUSIONS. Aortic dissection secondary to trauma is rare, however, the diagnosis should always be present in case of trauma due to deceleration, as it is vital for the survival of the patient and its timely treatment.

Factors influencing willingness to intervene as bystanders among adult residents living in crash-prone areas in the Ashanti region of Ghana

Introduction Formal prehospital emergency medical services cover only a small percent of the population in most low- and middle-income countries. Increasing the involvement of laypersons in prehospital first aid can be an important part of the response to injuries and other medical emergencies. We sought to understand factors associated with the willingness of laypersons in Ghana to provide first aid to road traffic crash victims. Method This cross-sectional study purposively sampled four crash-prone areas in the Ashanti Region and 385 participants were interviewed. A structured questionnaire was used to ask about their demographic characteristics, first aid knowledge, and perceptions about first aid. Factors affecting willingness to provide first aid were assessed using multivariable logistic regression. Results Most participants were male (57.7%) and young (median age 28 years). A large majority (82.9%) were willing to provide first aid to crash victims. However, only 43.1% had been trained in first aid and only 40.4% had adequate knowledge of first aid (≥ 70% correct). Factors associated with willingness to provide first aid included first aid knowledge (aOR 17.27 for moderate knowledge vs. low knowledge, p=0.018; aOR 13.63 for adequate knowledge vs. low knowledge, p=0.030) and positive attitudes towards first aid, including the feeling that: every person should be trained in first aid (aOR 2.98, p=0.025), first aid increases survival (aOR 2.79, p=0.046), it is important to learn first aid (aOR 2.40, p=0.005), and bystanders have the responsibility to give first aid (aOR 4.34, p<0.001). Conclusion A high percentage of people in these crash-prone areas of Ashanti Region, Ghana were willing to provide first aid. However, under half had been trained in first aid or had adequate knowledge of first aid. A major implication of these findings is the need to increase the availability of quality training in first aid in these areas.
