Objectives: There are contradictory results regarding the effects of foot reﬂexology on postoperative pain and hemodynamic status in patients undergoing coronary artery bypass graft (CABG). Therefore, the present study aimed to investigate the effects of foot reﬂexology on post-sternotomy pain and physiological parameters in patients undergoing CABG.
Materials and Methods: This randomized clinical trial was conducted on 40 women in Shahid Madani hospital of Tabriz in 2019. The sample size was determined based on previous studies using a formula and the participants were randomly assigned to treatment (n=20) and control (n=20) groups. In addition, all participants completed a three-part questionnaire (i.e., demographics, the visual analog scale, and hemodynamic symptoms forms) before and 40 minutes after the intervention. Then, the women in the test group received 20 minutes of left foot reﬂexology based on the existing method while those in the control group received no intervention. The data were statistically analyzed using the Kolmogorov–Smirnov and chi-square tests, as well as the paired sample and independent t tests at the signifcance level less than 0.05.
Results: The results indicated that the intervention signifcantly reduced systolic (P=0.001) and diastolic (P=0.005) blood pressures, along with heart (P=0.003) and respiratory (P=0.041) rates. Further, foot reﬂexology signifcantly decreased the severity of postoperative pain in the treatment group (P=0.003).
Conclusions: Overall, the study fndings revealed that foot reﬂexology had positive effects on the stability of hemodynamic status and thus relieved postoperative pain in patients undergoing CABG.
