Abdominal surgeries are defined as procedures carried out by surgeons for the children's abdominal regions for treating a medical condition. Pediatric surgical problems are a broad spectrum of surgical condition that occurs in children. Sometimes, it is considered a proper option of pediatric management to save children's lives and prevent and decrease disabilities and death. Aim: evaluate the effect of the acupressure technique on gastrointestinal problems and pain control for children post-abdominal surgeries. Methods: the study was a quasi-experimental research design and used for 80 children from the Tanta Main University Hospital's pediatric surgical department. Tools: were used to collect data: A structured Interview Schedule to assess the socio-demographic characteristic and medical history of children, a Rhodes index of nausea and vomiting form to assess nausea and vomiting, and a visual analog scale to assess nausea, vomiting and pain. Results: The current study found statistically significant differences in the occurrence of postoperative nausea, vomiting, and pain on the first- and second-days following implementation. Conclusion: There are a significant improvement in the children's nausea, vomiting, and pain after abdominal surgeries. Recommendations: Acupressure should be utilized as a collaborative nursing intervention method to minimize post-operative gastrointestinal side effects (nausea and vomiting) in pediatric surgery patients.
