Routine blood test usually refers to the extraction of venous blood and its laboratory tests, which can observe the changes in the number of blood cells in the blood, morphology and distribution and other indicators, which can understand whether the patient has bacterial or viral infections, and whether it is necessary to carry out preoperative anti-infective treatment and other functions. Coagulation time test usually refers to the time consumed from blood collection to blood coagulation after drawing venous blood, which can clarify whether the patient’s hemostatic function is defective or not when the test is performed before surgery. Anti-infection treatment before surgery can prevent complications such as accidental bleeding during surgery. Failure to administer anti-infective treatment may increase the brittleness of the tissues and raise the chances of unintentional bleeding during surgery. In addition, chest radiographs, lung ct, electrocardiogram, cardiac ultrasound, abdominal ultrasound and other examinations should be improved. Patients should be adequately prepared psychologically to prevent blood pressure fluctuations. The preparations made before gallstone surgery are to ensure a foolproof operation, and patients should actively cooperate.
