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.
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.
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 p=0.225, respectively).
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.
本研究旨在为行冠状动脉旁路移植术（CABG）的患者提供适当的术前支持条件，以改善其焦虑和生命体征。
本临床试验研究于 2019 年在伊朗哈马丹法什奇安医院对 90 例行 CABG 手术的患者进行。采用便利抽样法选取样本，并随机分为三组：对照组（n=30）、干预组 1（n=30）和干预组 2（n=30）。对照组仅接受病房常规术前咨询，并按常规进入手术室；干预组 1 和干预组 2 另外接受两次咨询，然后干预组 1 按常规进入手术室，而干预组 2 由咨询师在手术室陪同进入。使用包括人口统计学特征、生命体征图表和 Spielberger 状态-特质焦虑量表在内的三部分问卷收集数据。
结果显示，三组患者进入手术室后的平均焦虑水平存在显著差异（干预组 2 低于干预组 1 和对照组，p<0.001；干预组 1 低于对照组，p<0.001），三组患者的收缩压、心率和呼吸率也存在显著差异（p<0.001），但三组患者的体温和舒张压的平均值没有显著差异（p=0.59 和 p=0.225）。
我们的研究结果表明，术前咨询和咨询师陪同进入手术室可以降低行 CABG 患者的焦虑水平和生命体征的稳定性。
