Objectives:There are contradictory results regarding the effects of foot reflexology on postoperative pain and hemodynamic status in patients undergoingc ABG. 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. The participants were randomly assigned to the treatment group (n=20) and the control group (n=20). All participants completed a three-part questionnaire (demographics form, the visual analog scale (VAS) form, and hemodynamic symptoms form) 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 and those in the control group received no intervention. The data were statistically analyzed using the Kolmogorov–Smirnov test, chi-square test, the paired sample t-test, and the independent t-test at the significance level less than 0.05.
Results: The results indicated that the intervention significantly reduced systolic blood pressure (p=0.001), diastolic blood pressure (p=0.005), heart rate (p=0.003), and respiratory rate (p=0.041). In addition, foot reflexology significantly reduced the severity of postoperative pain in the treatment group (p=0.003).
Conclusion: The study findings indicated that foot reflexology had positive effects on stability of hemodynamic status and relieved postoperative pain in patients undergoing cABG.
