Theeffect of family presence at the bedside on serum cortisol levels and physiological indexes in patients hospitalized in intensive care unit

The aim of this study was to examine the effect of family presence at the bedside on serum cortisol levels and physiological indexes increasing in stressful situations. Family has a significant role inrecoveryof patients. Stress andanxiety are perceived reasons for limiting visitation in critical care units. This was an interventional study performed in intensive care units of three teaching hospitals in Tehran، Iran. Thirty and six blood samples of 18 patients were taken for measuring serum cortisol level and physiological indexes during their admission in the critical care settings with restricted visitation. The samples were taken، before family presence and then، one hour after visitation. Simultaneously، blood pressure and heart rate were recorded. The blood samples were immediately centrifuged and plasma stored at 200C until laboratory measuring. Total serum cortisol level was measured using electrochemiluminescence method. Data were analyzed using SPSS version 21. Therewasnostatistically significant difference inserumcortisol levels (P=0. 70)، systolic blood pressure (P=0. 93)، diastolic blood pressure (P=0. 98)، and heart rates (P=0. 60)، before and after visitation. Family visitation doesn''t cause stress. Unlike some common belief about relationship between family presence and stress in patients، it can be concluded that family visitation can be permitted، if patient desires.
