Surgery is a form of medical therapy that can cause stress because it poses a threat to a person's body, integrity and soul (Mazzotta et al., 2020). The surgical process is also often associated with high treatment costs, infectious complications, perioperative nausea and vomiting (PONV), and readmissions (Carmichael et al., 2017). An integrated and continuous nursing care process can make a difference between a negative or positive surgical experience and can influence the client's recovery process (Abeles et al., 2017). Complementary therapy is known as traditional therapy combined in modern medicine. Complementary is the use of traditional therapy into modern medicine (Tóth et al., 2018). Some have been scientifically proven, for example, touch therapy to increase relaxation, reduce pain, reduce anxiety, speed up wound healing, and make a positive contribution to psychoimmunological changes (Niu et al., 2021). So it is necessary to carry out a systematic review of complementary therapies, especially acupressure, which is used to treat complaints of nausea and vomiting in post-abdominal surgery patients to identify the effectiveness of acupressure therapy for post-operative nausea and vomiting in post-abdominal surgery patients. The research design that will be carried out is a systematic review using the PRISMA flow diagram. Researchers used PIO and searched for articles that were in English and published from 2013 to November 2023. The databases used were Proquest, Pubmed, Sage, Clinical Key Nursing, Science Direct and Google Scholar. Researchers use the Covidence tool to carry out the data selection process through to extraction and use the CASP instrument to evaluate research articles. Eight articles were identified and analyzed. Five articles used an RCT design, one article used a Prospective Cohort design, and one article used a semi-experimental design. The sample size of the reported studies ranged from 60 to 227 people conducted in various geographic regions such as Turkey, Iran and China. Acupressure therapy used at several points has been proven to help reduce PONV in post-abdominal surgery patients. Acupressure therapy can reduce PONV complaints in post-abdominal surgery patients.
