Video Transcription

Video Summary

In this presentation, the speaker discusses the implications of zinc in critical illness. They start by highlighting cases where zinc deficiency occurred in critical care patients, such as those with high-output fistula or bile leak. The speaker then explains the functions of zinc in the body, including its role in metabolism, immune system, and as an antioxidant. They discuss how zinc is absorbed in the body and the potential causes of zinc deficiency in critical illness, such as protracted diarrhea, burns, and renal insufficiency. The speaker also mentions that zinc deficiency can result in various symptoms, including skin rash, poor wound healing, altered taste, glucose intolerance, and inflammation. They emphasize the importance of monitoring zinc levels in patients with gastrointestinal losses, burns, renal replacement therapy, and other conditions. However, the speaker concludes by highlighting that there is limited evidence to support the use of mega doses of zinc in critical illness, including in cases of COVID-19.
