Adrenal surgery is usually a major surgery, but the size of the surgery is also related to the risk of the surgery and the severity of the disease. The adrenal gland is a hormone-secreting organ in the human body, and the aldosterone it secretes is directly involved in the kidney’s regulation of water and salt metabolism to maintain blood pressure balance. Therefore, intra-operative blood pressure fluctuations are often present, thus endangering the patient’s life, and therefore most of them belong to the category of major surgeries. Common adrenal surgeries include adrenal adenoma surgery, adrenalectomy surgery and so on. 1. Adrenal adenoma surgery: adrenal adenomas are mostly benign, and treatment is mainly based on surgical resection, usually using minimally invasive surgery, which can be designated as a minor surgery at this time, but if the preoperative preparations are not adequate, the patient may experience abnormal sympathetic excitation, hypotensive shock or even death and other risks during the operation. 2. Adrenalectomy: The adrenal gland is usually on the upper medial side of the kidney, with large blood vessels on the inner side, the diaphragm above, and the kidneys below. The adrenal gland is also rich in blood vessels, so the surgery is relatively troublesome, and violent blood pressure fluctuations may occur during the operation, so the surgery is more risky, and belongs to the larger surgery. Both minor and major surgeries are associated with certain surgical risks. It is recommended that patients must be examined under the guidance of a doctor before undergoing adrenal surgery in order to clarify the cause of the disease, and adequate preparation must be made before the surgery. After the operation, medication should be taken according to the doctor’s instructions, and if there is any discomfort, inform the doctor in time.
