1.2. Nutrition and Vitamins
The benefits of nutritional supplementation were assessed in
few RCTs, with mixed results (Banks, Graves, Bauer, & Ash, 2013;
Bourdel-Marchasson et al., 2000; Houwing et al., 2003). A review on the
benefits of nutritional support on the development of PrUs in intensive
care units (ICUs), by Theilla (2013) concluded that “ the paucity of RCTs
focusing on intensive care unit (ICU) nutrition in the support of wound
healing and the prevention of pathologic healing precludes formulation
of evidence-based guidelines for clinicians”(p. 186).
