Completion of cardiac ultrasound before cholecystectomy is routinely recommended in clinical practice. Preoperative examinations such as cardiac ultrasound can be used to adequately assess the risks of surgery and anesthesia, and to prevent the occurrence of complications. Cholecystectomy usually requires general anesthesia, and the application of anesthesia drugs may affect the physiological stability of the patient, and the trauma and bleeding caused by the surgery will put the patient in a state of stress. Therefore, in order to improve the safety of surgery and anesthesia, it is often recommended that the patient completes the routine examination of blood and urine, liver and kidney function, coagulation function, infection index, electrocardiogram, and cardiac ultrasound before the surgery. By completing such examinations, factors that may affect the surgery can be detected and corrected in time, so that the patient can cope with the surgery in the best condition, and patients who are not suitable for the surgery can also be screened out to reduce the risk of the surgery.
