Blood type: used for blood preparation.
Liver and kidney function: determine whether there are underlying diseases.
Inspection related to infectious diseases: to determine whether there are infectious diseases, some hospitals have special hepatitis tables in operating rooms, so the disinfection of postoperative instruments is more strict.
Coagulation: combined with platelet count to exclude bleeding-prone diseases and avoid excessive bleeding during operation.
There should also be electrocardiogram to evaluate cardiac function and abdominal ultrasound to check whether there is effusion in the appendix.
If you have a basic disease in the past, you should do relevant examinations (for example, the elderly may have lung function), so as to prevent problems before they happen and avoid intraoperative accidents.
