Studies of preoperative educational interventions with patients having cardiac surgery suggest that the life-threatening nature of this type of surgery impedes learning and undermines the effectiveness of preoperative education in the immediate preoperative period. In this study the effectiveness of preadmission preoperative education for patients having coronary artery bypass graft surgery (CABG) was investigated. The sample consisted of 40 patients scheduled for an initial, elective CABG procedure. A randomized, experimental, posttest-only design was used. Subjects in the experimental group received both preadmission and postadmission preoperative education; those in the control group received only routine postadmission preoperative education. Outcome measures were (1) preoperative knowledge of CABG surgery and routine, (2) postoperative state anxiety, (3) postoperative mood state, and (4) physiologic recovery. Subjects in the experimental group had significantly higher preoperative knowledge levels, more positive mood states, and more favorable physiologic recoveries than those in the control group.
对心脏手术患者进行术前教育干预的研究表明，这类手术危及生命的性质会妨碍学习，并削弱术前教育在术前即刻的效果。在本研究中，对冠状动脉搭桥手术（CABG）患者进行入院前术前教育的效果进行了调查。样本包括40例计划进行首次择期CABG手术的患者。采用了随机、实验性、仅后测设计。实验组的受试者接受了入院前和入院后术前教育；对照组的受试者仅接受常规入院后术前教育。结果指标包括：（1）CABG手术及常规的术前知识；（2）术后状态焦虑；（3）术后情绪状态；（4）生理恢复情况。实验组的受试者在术前知识水平、情绪状态更积极，生理恢复情况也比对照组更有利。
