Abstract:

This research was conducted as a descriptive research for the purpose of identifying the orthostatic hypotension and orthostatic intolerance frequency which develop after the early period mobilization in the patients who have been applied coronary artery graft surgery. The research population consisted of 108 patients who stay after the surgery in cardiovascular intensive care units of Private Ankara Güven Hospital and Gazi University Health Research and Application Center. In data collection, it was used a questionnaire form developed by the researcher. It was identified the orthostatic hypotension development frequency by comparing the hemodynamic data during the mobilization processes of the patients in the early period after the surgery and their hemodynamic data before the surgery. In data evaluation, it was used descriptive statistics, independent sample t-test, Chi-squaretest, Mann-Whitney U test and Paired Samples t test. It was identified that 72.2% of the patients consist of male patients and that their body mass indexes as overweight (28.14 ± 4.70). After the surgery, the patients has mobilized after 19.23 ± 3.08 hours. As a result of the comparison between the data one hour before the surgery and the mobilization stages, it was observed a significant increase in heart rate while it was observed significant decreases in systolic blood pressure and the diastolic blood pressure in all stages of the mobilization (p<0.001). The patients have frequently determined intolerance symptoms (%26.9) in the 2nd stage of the mobilization process while they have been mobilizing. Statistically, it was identified that the orthostatic intolerance prevalence are similar both in the patients who developed orthostatic hypotension and the patient who did not develop orthostatic hypotension (p= 0,269). In accordance with the results obtained from the research, it is suggested that the healthcare personnel should raise awareness towards orthostatic hypotension and orthostatic intolerance which develop after early mobilization and the patients should mobilize with regard to a written protocol.
