Combined Acupressure Effects on Post-Thoracotomy Pain and Lung Volume

Many non-drug applications such as music therapy, transcutaneous electrical nerve stimulation, cryotherapy, acupuncture, electroacupuncture are used in pain management after thoracic surgery and to reduce analgesic use. Acupuncture is an application that provides the balance of energy flow (Qi) on meridians with thin needles placed at certain points of the body, which has been widely applied in China for more than 4000 years. Factors such as trauma and surgical incision disrupt the energy flow between meridians and cause problems in organ groups where meridians are effective. Acupuncture is accepted as an application that helps to balance this energy flow. Acupressure application, which is included in nursing practices, is a holistic non-pharmaceutical application based on acupuncture. Acupressure is a holistic treatment method that includes manual and noninvasive methods that provide stimulation to acupuncture points with pressure instead of needle stimulation. The point where acupressure will be applied is selected among the acupuncture points on the relevant meridian according to the problem existing in the individual. In acupressure application, pressure can be applied to a single point or more than one point consecutively.In acupressure application, it is reported that pressure can be applied to a single point, as well as stimulating multiple points consecutively will increase the desired effect. As the preferred acupuncture key points on the meridians, points on the hand, finger, wrist, palm, elbow, knee, and feet are often preferred. Acupressure tactilely reduces the sensation of pain by stimulating Aβ nerve fibres; increases the pain threshold by supporting the release of endogenous opioids; regulates the transmission of pain signals by secreting serotonin and norepinephrine, which are neurotransmitters responsible for the regulation of pain. In a randomised controlled study, the efficacy of acupressure in the treatment of postoperative pain in patients undergoing thoracoscopic surgery was examined. The participants in the experimental group were acupressured three times a day for two days at LI11, LU7, LU9, LU5, LU1, LU2, TE5, TE6, PC4, PC6 and LI4 acupressure points. In the control group, routine treatment of the clinic was applied and acupressure was not applied. After acupressure application, the pain score of the experimental group was found to be lower compared to the control group (p \< 0.001). Similarly, it is reported in the literature that the use of acupressure is one of the best options for the relief of postoperative pain. It is also reported in the literature that acupressure can effectively improve lung function, dyspnoea and quality of life of patients with pneumonia.

Non-drug applications planned for the expected pain in the early postthoracotomy period are important in terms of reducing respiratory complications, improving the quality of pain management and supporting patients. When the literature is examined, there is no study examining the effect of acupressure on pain and lung volume during deep breathing and cough exercises, which have an important role in maintaining and improving lung volume after thoracotomy.
