ABSTRACT

OBJECTIVE: To investigate the roles of hemodynamic factors and oxygenation on the incidence of pressure ulcers in patients in the ICU on mechanical ventilation.

 

METHODS: This prospective analytical cross-sectional study was performed in several ICUs for a period of 8 months in Iran. Researchers checked patients for pressure ulcers on a daily basis. They collected demographic, hemodynamic, and oxygenation data until a pressure ulcer occurred, the patient's artificial airway was removed, the patient died, or the patient was discharged.

 

RESULTS: From August 2017 to February 2018, a total of 2,581 patients were admitted to the study ICUs; of these, 133 patients were eligible for the study. The results indicated that 41.4% (n = 55) of the patients ended up with pressure ulcers. Investigation of the variables using a Cox regression model showed that, among other variables considered in this study, age, mean arterial pressure, and positive end-expiratory pressure in the mechanical ventilator can contribute to the risk of pressure ulcers.

 

CONCLUSIONS: Providers should pay attention to changes in hemodynamic parameters, especially mean arterial pressure; carefully determine the most appropriate positive end-expiratory pressure for patients connected to mechanical ventilation; and take special care of susceptible groups such as older adults and hospitalized patients to decrease the incidence of pressure ulcers.
