Recommendations for airway management in a suspected or confirmed case with COVID-19. A protocol of the Department of Cardiovascular Anesthesia of the National Institute of Cardiology Ignacio Chávez / Recomendaciones para el manejo de la vía aérea en caso sospechoso y/o confirmado con COVID-19. Protocolo del Departamento de Anestesiología Cardiovascular del Instituto Nacional de Cardiología Ignacio Chávez

The new coronavirus SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2), detected in Wuhan, China, causes coronavirus disease 2019 (COVID-19), which was declared pandemic, and has caused more than 19 million confirmed cases and more than 700 thousand deaths worldwide. When our institution was converted to COVID's hospital since early April 2020, specific care protocols were developed, with the aim of improving the quality of care and safety of patients and the staff involved in their management. Airway management represents one of the highest risks of direct contact infection with aerosol generation (orotracheal intubation, secretion aspiration, extubation, cardiopulmonary resuscitation, high flow oxygen therapy, noninvasive ventilation, and invasive ventilation). We present the current recommendations for airway management as well as a step-by-step airway management protocol to carry out a more secure procedure based on the literature reported so far.

El nuevo coronavirus SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), detectado en Wuhan (China), causante de la enfermedad por coronavirus 2019 (COVID-19), que se declaró como pandemia, ha causado más de 19 millones de casos confirmados y más de 700 mil muertes en el mundo. Nuestra institución se reconvirtió a hospital COVID desde principios de abril del 2020, con lo que se desarrollaron protocolos de atención específicos, con el objetivo de mejorar la calidad de atención y seguridad de los pacientes y el personal involucrado en su manejo. El manejo de la vía aérea representa uno de los riesgos más altos de contagio por contacto directo en la generación de aerosoles (intubación orotraqueal, aspiración de secreciones, extubación, resucitación cardiopulmonar, terapia de oxígeno de alto flujo, ventilación no invasiva y ventilación invasiva). Presentamos las recomendaciones actuales para el manejo de la vía aérea, así como un protocolo de manejo paso a paso para llevar a cabo un procedimiento con mayor seguridad basados en la literatura reportada hasta el momento.

[Glucose-insulin-potassium (GIK) solution: cardioprotective effects of insulin]. / Solución de glucosa-insulina-potasio (GIK): efectos cardioprotectores de la insulina.

In the Anesthesiology Department of the Instituto Nacional de Cardiología The medical staff uses the glucose insulin potassium i.v. for myocardial protection. The energy is dereived from lipidic beta oxidation, glucose breakdown and amino acid catabolism in mitochondria. In myocardial ischemia, from de aortic cross clamping, the metabolic myocardial substrates diminished as well as the energy produced by adenosine (ATP). During myocardial ischemia, an increase in long chain lipids emhances mitochondrial permeability, promotes depletion of citochrome C and lost of the capability of transmembrane regulation. In the hipoperfused myocardium, by coronary vasoconstriction, short chain fatty acids oxidation predominates, if fatty metabolism during reperfusion is elevated. More of them will enter [IBM1] the Krebs cycle and, as a consequence, less energy will be produced. The glucose-insulin-potassium solution provides the glucose needed by the myocardium in reperfusion conditions and protects the cellular membrane's integrity as well as pumps and ionic channels, it allows maintaining the action potential probably because ATP-depended channels block and prevent potassium loss, it reduces the cytosol calcium overload and prevent cardiac arrhythmias, preserves the sodium ATPasa pump avoiding the rise in cytosolic sodium; glucose prevents the production of free oxygen radicals. Fatty acids, during ischemia, are responsible for the metabolism and elevation of enzymes, such as acilcarnitine and acylcoenzime-A, which promote intracellular calcium overload and arrhythmias. The insulin has anti-inflammatory effects and anti-apoptoic effects. When blood glucose is controlled during the perioperative period the mortality is reduced.
