What examinations are required before surgery?

Hello, Prior to surgery, the following preoperative evaluations are required: 1. **Cardiac function assessment**: An evaluation of cardiac function is essential before surgery. This includes completing an electrocardiogram (ECG) and echocardiography to comprehensively assess cardiac status. 2. **Pulmonary function assessment**: Pulmonary function must be evaluated prior to surgery. A chest CT scan and pulmonary function tests should be performed to determine whether the patient has pulmonary infection and whether pulmonary function is adequate to tolerate surgery. Consultation with relevant departments may be necessary if indicated. 3. **Complete blood count (CBC)**: A CBC is mandatory before surgery. This helps identify conditions such as anemia, thrombocytopenia, or leukocytosis. 4. **Liver and kidney function and electrolyte panel**: Assessment of hepatic and renal function, along with serum electrolytes, is required preoperatively. This enables detection of hepatic or renal insufficiency and hypoalbuminemia. We hope this information is helpful. Thank you!
