The interactive effect of preoperative consultation and operating room admission by a counselor on anxiety level and vital signs in patients undergoing Coronary Artery Bypass Grafting surgery. A clinical trial study
Objective. The purpose of this study was to provide
appropriate preoperative supportive conditions to improve
anxiety and vital signs for patients undergoing Coronary
Artery Bypass Grafting -CABG- surgery.
Methods. This clinical trial study was performed on 90 patients undergoing
CABG surgery in Farshchian Hospital of Hamadan, Iran
in 2019. Sample was selected by convenience and were
randomly divided into three groups: control (n=30),
intervention1 (n=30), and intervention2 (n=30). The
control group received only the routine preoperative
counseling of ward and admitted to the operating room
as usual; the intervention1 and intervention2 groups in
addition received another two counseling sessions, then
the intervention1 group was admitted in the operating room as usual, but the intervention2 group was admitted by the counselor in the operating
room. Data were collected using a three-part questionnaire including demographic
characteristics, vital signs chart, and the Spielberger’s State-Trait Anxiety Inventory.
Results. The results showed that there was a significant difference in the mean
anxiety of the three groups after admission in the operating room (intervention2 was
lower than intervention1 and control groups, p<0.001; and intervention 1 group
was lower than control group, p<0.001) and also there was a significant difference
between the mean systolic blood pressure, heart rate and respiratory rate of the
three groups (p<0.001) but the mean of the variables of temperature and diastolic
blood pressure in the three groups were not significantly different (p=0.59 and
Conclusion. Our results revealed preoperative consultation
and admission in the operating room by the consultant can reduce the level of
anxiety and stability of vital signs of patients undergoing CABG.
