Ovarian laparoscopic surgery is when an ovarian cyst requires laparoscopic surgery to remove it. The tests that need to be done include routine blood tests, coagulation time tests, ultrasound tests, electrocardiograms, and tests for related infectious diseases. 1. Routine blood test: Routine blood test is the basic blood test for physical examination, which mainly includes the test of white blood cells, red blood cells and platelets. Find out whether the white blood cells, red blood cells and platelets are normal. 2. Coagulation time test: The main check is whether the patient’s coagulation function is abnormal or not. Generally, the coagulation time test must be carried out before the operation, and if there is any abnormality, it may lead to hemorrhage in the operation. 3. Ultrasound examination: Ultrasound examination can check the size and number of the patient’s ovarian cysts, which can give the doctor a perfect preoperative assessment, selection and formulation of reasonable surgical plan. 4. Electrocardiogram: check whether the patient has symptoms such as arrhythmia and myocardial ischemia. 5. Related infectious disease examination: check whether the patient has hepatitis B, AIDS, syphilis, hepatitis C and other infectious diseases. In order to ensure the safety of patients, nest laparoscopic surgery before the need to improve the relevant auxiliary examination.
