Patients with appendicitis require anti-infection, intravenous rehydration therapy, and simple infusion of fluids is not expensive. Glucose, saline and basic vitamin needs, including water-soluble vitamins or fat-soluble vitamins, as well as the amount of potassium chloride needed per day should be supplemented, and the cost of rehydration fluids will not exceed about 100 yuan per day. Appendicitis is a disease that should be diagnosed early and promptly with the option of surgery. Because the appendix is a blind end, infection is prone to secondary sepsis, necrosis, perforation, and complications of peritonitis, in which case surgery will increase the difficulty of surgery, as well as increase the patient’s financial burden and physical pain, far more than the cost of infusion, so patients should undergo surgery early.
