CONCLUSION
In our study, although no apparent contribution of DEX on reducing mortality and intubation rates has been demonstrated, a significantly longer time before intubation was determined for this agent. Patients with DM, CHF, and on insulin therapy less required DEX infusion whereas patients treated with IVIG for severe COVID-19 more required DEX infusion. Prospective randomized controlled trials with large sample sizes are needed to decide whether DEX therapy has a positive effect on mortality and intubation rates in patients with COVID-19.
