Abstract:
Lower-extremity amputations are a major concern for the current state and future of healthcare, with ischemia contributing significantly to this issue. This is an infrequent but serious complication of vasopressor use. Unfortunately, there is little research existing on the topic and even fewer guidelines on treatment options. Vasopressors are often used to treat life-threatening hypotension. However, ischemic changes associated with vasopressor use often do not present for several days. It is frequently recommended that patients undergo amputation when the first signs of ischemia occur. This approach, however, does not allow for the full process of demarcation, making it difficult to determine which portions of the lower extremity will remain viable. This is a case study of a 37-year-old man who developed severe complications from COVID-19 and was subsequently admitted. Because of a complicated hospital course, he required the use of vasopressor medication that subsequently led to the development of ischemic changes to his bilateral forefeet and hands. Through a prolonged period of demarcation and the collaboration of multiple specialties, the patient was able to salvage each limb and maintain his functionality.
