Purpose:
More than 86% patients experience moderate to severe pain after thoracoscopic surgery. A combination of diverse nonpharmacological pain relief methods is a developing trend for pain management. The purpose of this study was to explore the effect of acupressure in reducing pain after thoracoscopic surgery.
Design:
A Randomized controlled study with purpose sampling was used for this study. Patients who underwent thoracoscopic surgery at a medical center in central Taiwan were enrolled. Study data was collected from September 2020 to April 2021 after the approval of the institutional review board. A total of 100 participants were randomized into two groups (49 and 51 in the experimental and control groups, respectively).
Methods:
Participants in the experimental group received acupressure at the Neiguan (PC6) and Shenmen (HT7) acupoints thrice a day for 2 days, whereas those in the control group received routine treatment and did not receive acupressure. The measurement included questionnaires for the collection of general information, physiological information, and disease rating scale. The Visual Analogue Scale-Pain (VAS-P) was used to measure the severity of pain. SPSS statistical software was used for data analysis. Independent sample t-test and chi-squared test were used for descriptive statistics, and paired t-test and linear mixed model were used to examine the effect of acupressure in alleviating pain.
Findings:
After acupressure intervention, the pain score of the experimental group was lower than that of the control group, and this difference was significant β = 17.76, p < 0.001 on day 1 after intervention; β = 19.80, p < 0.001 on day 2 after intervention. The postoperative pain score in the experimental group on day 2 after intervention was significantly lower than that in the control group (t = 2.039, p = 0.044). After the subjects received acupressure, pain index significantly decreased after considering the interaction between time and group (p < 0.001). Regardless of the type of surgery, there were significant differences in pain index when the interaction between time and group was considered (p < 0.001).
Conclusions:
This study provided an experimental basis that acupressure can help in pain management in patients after thoracoscopic surgery, and the pain relief results become more significant as the duration of intervention increases.
Clinical Relevance:
Acupressure is effective in relieving postoperative pain in any type of thoracoscopic surgery. Nurses can use acupressure to help control pain in patients after thoracoscopic surgery.
