Objective: Despite using the most appropriate methods of prevention, the incidence of pressure ulcers is still considered as a major problem of health care in all health systems. A group of patients at high risk for this problem, there are patients who are undergoing open heart surgery. But few studies have been done about the risk of pressure ulcers in this group of patients. This study aimed to investigate the relationship between hemodynamic statuses with the risk of pressure ulcers development in patients after heart surgery is done. Materials and methods: This cross-sectional study conducted in cardiac intensive care unit of Bu Ali Sina hospital in Qazvin. Eighty two patients who were undergoing cardiac surgery were selected by convenience sampling method. The risk of pressure ulcers on three times, before surgery, after surgery (the patient’s consciousness) and at discharge was evaluated by using the Braden scale and international staging pressure ulcers (stage 6). As well as demographic specifications, hemodynamic status, including systolic blood pressure, diastolic blood pressure, mean arterial blood pressure, heart rate, central venous pressure and the patient's medications on a daily basis were recorded by the researcher. Data analysis was performed using SPSS 16 software. Results: Of the 82 patients, 36 were women (43.9%) and 46 males (56.1%). The mean ages of patients were 10.52 ± 60.93 and the mean of intensive care unit stay was 2.87 ± 0.96. The risk of pressure ulcers with an average diastolic blood pressure on the first day (p = 0.04), the mean central venous blood pressure in the second day (p = 0.01), mean heart rate on the second day (p = 0.04), age (p = 0.000 ), duration of hospitalization in a special section (p = 0.002), presence of diabetes (p = 0.04), cardiac surgery (p = 0.01), smoking (p = 0.000) and the pump during surgery (p = 0.03) had a significant relationship. Conclusion: according to finding of present study, patients who are undergoing cardiac surgery, are at high risk for pressure ulcers development and factors such as diastolic blood pressure, central venous pressure, increased heart rate, increased age, duration of hospitalization, presence of diabetes, previous surgery, smoking and working the pump during surgery could be increased this risk.
