Abstract:
Background and Aim
Sedation after coronary artery bypass graft surgery can prevent the side effects of the treatment. The purpose of this study was to determine the effect of controlled sedation based on the Richmond scale on the duration of mechanical ventilation and the changes of blood pressure in patients following coronary artery bypass graft surgery.Methods & Materials: In a single blind randomized clinical trial (IRCT2017050517693N2) from June to August 2017, a convenience sample of 80 patients after coronary artery bypass graft surgery, hospitalized in the intensive care unit of Heshamat Center, Rasht, were selected and randomly allocated into two groups (each group=40). Sedative drug dose was determined using the Richmond agitation sedation scale in the intervention group and determined routinely (based on hemodynamic changes) in the control group. Pain as a confounding variable was evaluated using CPOT tool. Data were analyzed by descriptive statistics and Chi-square, Mann-Whitney, independent t-test and repeated measures ANOVA using the SPSS software version 22.
Results
The mean age of samples was 59.89±7.53 and 66.7% of them were male. There was a significant difference between two groups in the duration of mechanical ventilation (PConclusion
Utilizing the Richmond tool can reduce the patients dependence on ventilator and changes in arterial pressure. Also, using this tool can prevent unnecessary and early administration of sedative and vasopressor drugs in patients.Keywords:
