Serum trace element levels in COPD patient: The relation between trace element supplementation and period of mechanical ventilation in a randomized controlled trial

Abstract

Trace element (Se, Mn and Zn) status is altered in critically ill patients with COPD. The supplementation achieved a reduction in the period those patients spent on the mechanical ventilation. A larger multi-centre trial is required to confirm this preventive effect and to explore its applicability to other critical care conditions.
