虫垂炎 II: 診断研究と管理

A complete blood count (CBC) reveals leukocytosis, indicating an immune response to infection. Elevated C-reactive protein (CRP) levels serve as a marker for inflammation in the body. Together, these laboratory findings support the clinical diagnosis of appendicitis when combined with physical examination and imaging studies.

Ultrasound scans visualize the swollen appendix and assess its condition. CT scans provide detailed images highlighting abnormalities such as a distended appendix or an appendicolith, a calcified deposit within the appendix. Both imaging modalities are essential for confirming the diagnosis and guiding treatment decisions.

Uncomplicated appendicitis may be managed nonsurgically with antibiotic therapy to combat infection and pain management medications. However, surgical removal of the appendix, known as an appendectomy, remains the definitive treatment. Surgery can be performed using laparoscopic, minimally invasive, or open approaches depending on the patient's condition.

Preoperative care includes keeping the patient NPO (nothing by mouth) to prevent aspiration during anesthesia, monitoring vital signs closely, and administering prescribed pre-surgery medications. These measures prepare the patient safely for the surgical procedure and reduce perioperative complications.

Postoperative patients are placed in high Fowler's position to ease breathing and reduce pain. Analgesic medications manage discomfort effectively. Early ambulation is encouraged to decrease the risk of complications such as atelectasis and to promote circulation, supporting faster recovery.

Fluids and food are reintroduced gradually once bowel sounds are detected, indicating that the digestive system is recovering. Monitoring urine output is also essential to assess kidney function post-surgery. This gradual reintroduction prevents complications and supports proper nutritional recovery.

Discharge instructions include scheduling follow-up appointments, caring for the incision site to prevent infection, and adhering to activity restrictions, particularly avoiding heavy lifting for 2 to 6 weeks. Patients should also receive education on recognizing signs of normal wound healing and potential complications to ensure safe home recovery.
