ReviewPressure ulcer development and vasopressor agents in adult critical care patients: a literature review.
Critical care units provide technologically sophisticated care to the sickest patients in the healthcare system. The contribution of iatrogenic factors, including administration of pharmacologic agents such as vasopressors, to pressure ulcer (PU) development in adult critical care patients is understudied, thus less understood, but may be an important PU risk factor to consider in the critical care population. Vasopressor agents are potent vasoconstrictors commonly administered to critical care patients to elevate mean arterial pressure to counteract the effects of inadequate tissue perfusion and hypoxia; they have reemerged over the past decade in contemporary intensive care units as important first-line drugs in the treatment of shock states. ⋯ Increased vigilance regarding PU risk in critical care patients receiving vasopressor agents may be warranted. However, studies are needed to examine the effects of individual vasopressor agents and dosage and duration thresholds, as well as empirical investigation regarding the synergistic effect of multiple vasopressor agents administered simultaneously, on PU development in this population. Finally, research is needed to further elucidate vasopressor use as an independent risk factor for PU development in this population.

A retrospective, nonrandomized, beforeand- after study of the effect of linens constructed of synthetic silk-like fabric on pressure ulcer incidence.
A new, synthetic, silk-like fabric was developed for the purpose of providing bedding and patient gowns that manage moisture, friction, and shear when used between the patient and the healthcare support surface that may affect the development of pressure ulcers (PUs). A retrospective study was conducted to compare the incidence of hospital-acquired PUs in patients admitted to Telemetry, Urology, and Intensive Care Units before and after hospital linens were changed from standard to the synthetic (intervention) linens. Patient medical record data were abstracted for a period 12 weeks before (control) and 12 weeks following the linen change (intervention). ⋯ At discharge, 136 PUs were present in the control and 64 were present in the intervention group (P <0.001). The significant differences in the incidence of hospital-acquired PUs between the two groups suggest that linen type affects PU risk. Additional controlled clinical studies in high-risk patient populations are warranted.
