Studying the effect of guided relaxation on pain and physiological indices after coronary artery bypass grafting (CABG) surgery in patients admitted to Heshmat Hospital in Rasht
Introduction and purpose: Pain and relieving it are of the major challenges of nursing in care after CABG surgery. In this regard, the use of effective, simple, and cost-effective methods of pain relief with minimal side effects is considered. Thus, the present study has been conducted to determine the effect of guided relaxation on patientsí pain after CABG surgery.
Method: in the present study, which is a preliminary experimental study of before and after, 90 patients undergoing CABG surgery at the educational hospital of Heshmat in Rasht with the characteristics of the units studied were randomly selected. After signing written consent, the subjects were trained on how to implement Benson relaxation, which is a progressive relaxation, at the stage before the operation. Data collection tool in this study was a three-part questionnaire including 1) demographic data, 2) visual analog scale (VAS) of pain, and 3) sheet of recording values of physiological parameters (blood pressure, pulse, and respiration). Data were collected in the first 24 hours of the transfer of the patient from the ICU to the surgical ward two stages before intervention (with the announcement of pain by the patient) and after intervention. Data analysis was done using paired and independent t-tests and Pearson with SPSS version 12.
Results: The findings related to demographic characteristics of the majority of units studied were composed of men (78.9%), in the age group 41-55 years (51.1%), with an average age of 55 years and a standard deviation of 9.56 years, with third grade guidance-school degree (37.8%), history of hospitalization (71.1%) and surgery record (50%).
The findings showed a considerable reduction in pain and physiological parameters after intervention (p=0.0001). The mean and standard deviation of pain intensity before and after the intervention, and in terms of hospitalization history (p=0.04), and the mean and standard deviation of physiological parameters in terms of gender (p=0.05) and education level (p=0.36) were statistically insignificant.
Conclusion: The results showed that relaxation, as a complementary non-invasive therapeutic method, could cause a significant decrease in pain and physiological parameters in patients after CABG surgery.
