RESUMEN
A subset of patients with COVID-19 develops a severe inflammatory response that may lead to respiratory and multiorgan failure. Effective treatment strategies to mitigate or interrupt this self-destructive inflammatory process are limited. The local anesthetic lidocaine has anti-inflammatory properties in addition to its analgesic, antiarrhythmic, and sedating effects that may be beneficial in critically ill COVID-19 patients. We report the case of a patient with COVID-19 induced severe respiratory distress who was intubated and received supportive treatment including proning and neuromuscular blockade. He developed a strong inflammatory response that we treated with an intermittent lidocaine infusion resulting in subsequent resolution. This case occurred prior to emerging data from a large dexamethasone use trial that demonstrated a survival benefit from its use in hospitalized COVID-19 patients. At the time, lidocaine was the only anti-inflammatory medication our patient received.
RESUMEN
The ability to apply perioperative ultrasound techniques is a desirable skill for clinicians. We implemented a multimodal 13-day basic ultrasound course for 6 anesthesia interns. Their scores on a knowledge test increased after the course and were sustained and similar to those of 6 senior residents 90 days later. The interns acquired images of the heart in volunteers with little assistance after the course. They maintained their ability to acquire echocardiographic images on a simulator 90 days later with kinematic measures superior to the same seniors. Through this course, interns gained knowledge and skills equal to or greater than seniors.
