Monitoring and measuring magnesium (Mg) values is essential to prevent the development of numerous complications in critically ill patients. This webinar will describe why Ionized Mg (iMg) may offer a more reliable indicator of Mg status during acute illness than total Mg (tMg) concentrations. Dr. Abdullah M. Al Alawi, Sr. Consultant, UMC, Muscat, Oman will discuss the incidence of dysmagnesemia and the relationship between iMg and tMg. The clinical and biochemical characteristics as well as health outcomes and their association with iMg and tMg will be addressed. Dr. Alawi will also describe the use of point-of-care devices for rapid assessment of iMg in critical situations.
