Patients with appendicitis who present with total abdominal stomach pain are mostly suffering from suppurative appendicitis, and more severe cases may reach gangrenous, perforated appendicitis. When full abdominal pain of appendicitis occurs, surgical treatment options must be actively taken. During surgery, while removing the appendix, the abdominal cavity should also be explored for infected intestinal tubes, omentum, and pelvis, and pus moss and purulent exudate should be found, and active cleansing and postoperative drainage should be taken. Postoperative anti-inflammatory and symptomatic efforts should also be actively increased, and sensitive and highly effective antibiotics should be selected, with the addition of anti-anaerobic drugs, including metronidazole and ornidazole. For the pain caused by appendicitis after surgery, symptomatic pain treatment can also be taken appropriately. Clinically applied pain medications include diazoxide and tramadol, which are able to relieve inflammatory pain caused by postoperative abdominal incisions as well as abdominal viscera.
