Özet
Objective: In this study, the effect of different angles (0°, 30° and 45°) on hemodynamic and pulmonary artery pressure (PAP) measurements on intensive care unit patients in back position after cardiac surgery was examined. Material and Methods: The study was performed in Cardiovascular Surgery Intensive Care Unit after obtaining ethical committee permissions. The study group included 50 patients with pulmonary artery catheter, appropriate for study criteria. Patients' demographic information, position, and obtained hemodynamic data were recorded in the Patient Data Form. During data collection; patients were given 0°, 30° and 45° respectively increasing back positions and hemodynamic parameters measured in each position. In order to obtain reliable measurements transducers' level was adjusted according to the right atrium's external reference point. Study data; number and percentage, difference between hemodynamic measurements after positions were tested by Repeated Measurement Analysis of Variance (ANOVA) using the SPSS 15.0 program. Results: Valve surgery was applied in 30 patients (26%) and coronary artery bypass surgery was performed in 37 patients (74%). Twenty patients (40%) were female, 30 (60%) patients were male. Mean age was 58 ± 13 years. The average values of hemodynamic parameter measurements obtained after giving different angels of back positions (0°, 30° and 45°) to the patients were examined; the average values of heart rate, systolic, diastolic and PAP values were not statistically effected by back position changes (p> 0.05). Conclusion: The hemodynamic pressure measurement results obtained at 30° and 45° increasing angles of back positions were found similar to the results in 0° back position. These data suggest that hemodynamic measurements of patients with back levels up to 45° can be made safely without bringing patients to 0° supine position. Copyright © 2010 by Türkiye Klinikleri.
