https://revistaliteratura.uchile.cl/index.php/BA <p>El Boletín de Anestesia de la Universidad de Chile , esta orientado a&nbsp; difundir temas de Anestesiología y Medicina Perioperatoria al equipo de salud involucrado en la prestación de Anestesia . Este Boletín&nbsp; fue creado y editado por la Dra . Olga Herrera en conjunto con la Dra. Ana Luisa Muñoz ( Maestra de la Anestesiologia Chilena ,Q.E.P.D.). El objetivo de la revista es dar a conocer los cambios vetiginosos que afectan a nuestra especialidad y que intentan entregar una informacion actualizada a todos los Anestesiólogos y profesiones relacionadas , constituyéndose de esta manera a generar un aporte informativo a todos los Anestesiólogos de Hispanoamérica.</p> <p>El Boletín de Anestesia permaneció " dormido " por aproximadamente 19 años y a partir de hoy pretendemos despertarlo de su prolongado letargo y queremos mantener una periodicidad de un ejemplar cada semestre de manera inicial para luego ir aumentando su frecuencia conforme se estructure su demanda .</p> <p>Los artículos seran originales, los que serán revisados por revisores designados para tal efecto . Están invitados a publicar en este Boletín todos aquellos colegas de la Universidad de Chile que encuentren en este un canal de difusión de sus actividades de investigación y/o trabajos de revisión que sean un aporte para la Anestesiologia Chilena en todo el territorio Nacional.</p> Hospital Clínico Universidad de Chile, Departamento de Anestesiologia y Medicina Perioperatoria. es-ES Boletín de Anestesia 2735-6310 https://revistaliteratura.uchile.cl/index.php/BA/article/view/73489 A cardiac arrest must be quickly identified, and cardiopulmonary resuscitation initiated, activating in-hospital or out-of-hospital protocols. Once return of spontaneous circulation is achieved, post-cardiorespiratory arrest care begins. These should be focused on finding the etiology of the cardiac arrest in order to treat it, adequate monitoring, try to maintain homeostasis looking forward to appeasing the post-cardiac arrest syndrome that the patient is suffering and perform adequate prognosis. Anaesthesiology face cardiorespiratory arrests mainly within the operating room, recovery room, emergency room and in the intensive care unit. Many times, there is no immediate access to an intensive care unit bed, or referral to centers with access to coronary angiography and/or other procedures is required, which implies the management of these patients for variable times. For this reason, appeared the initiative to review the guidelines of the American Heart Association 2020 and European Resuscitation Council and European Society of Intensive Care Medicine guidelines 2021 for post-cardiorespiratory arrest care.

It occurs in approximately 1 in 100,000 anaesthesias, generally in patients with no history, and more in men than in women (2:1). Pathophysiologically, there is an abnormality of the ryanodine receptors in the striated muscles, which produces an excessive accumulation of calcium in the cytoplasm. The clinical presentation is variable: it generally begins with hypercapnia (92.2%) and sinus tachycardia (72.9%); occasionally rigidity is added (masseter in 26.7% and generalized in 40.8%); continuing with a variable combination of hyperthermia (52.2 to 64.7%) and other manifestations. Management focuses on hyperventilating, suspending triggers, initially administering dantrolene 2.5 mg/kg IV, correcting the internal environment (mainly hyperkalaemia), and cooling the patient externally and internally if necessary. The use of dantrolene should be early; it has a rapid effect monitorable through capnography and heart rate; it must be administered for at least 24 hours; and it has side effects that are usually not serious. Mortality has decreased from 75% in the predantrolene and precapnography era to 6% to 10% today.
