Background: In this meta-analysis, we aimed to determine the effect of non-pharmacological methods on pain in patients undergoing open heart surgery.
Methods: Scientific articles published between January 2002 and April 2022 were scanned in ScienceDirect, Scopus, PubMed, Web of Science, Google Scholar, Mendeley, Wiley Online Library databases. The keywords “open heart surgery,” “cardiovascular surgery,” “non-pharmacological,” “complementary medicine,” and “pain” were used in Turkish and English language. As a result of the search, 7,952 studies were identified and analyzed. Research data were obtained from 49 scientific articles.
Results: The total sample size of the studies included in the analysis was 3,097. The total effect size was found to be 3.070, with a 95% confidence interval of 2.522 at the lower limit and 3.736 at the upper limit. Non-pharmacological pain methods in open heart surgery included positive environmental experience, distraction, massage therapy, hand massage, foot massage, acupuncture therapy, lavender essential oil inhalation, cold application, music therapy, breathing and relaxation exercises, neurolinguistic programming, guided visualization, imagery, therapeutic touch, osteopathic treatment, and transcutaneous electrical nerve stimulation.
Conclusion: The pain of patients who underwent open heart surgery with non-pharmacological methods combined with pharmacological methods was three times less than those without non-pharmacological methods. Based on these findings, non-pharmacological methods are recommended for use due to their ease of application, and low side effects.
