A professor’s post, “Ten lives can’t be exchanged for one of mine,” caught fire. Not to mention how rich the professor is and how much he needs high-end medical care, it is indeed a waste of medical resources to stay in the CCU alone. It is a kind of ICU (Intensive Care Unit), which is translated as “intensive care unit” in China and “intensive care unit” in Hong Kong. ccu refers specifically to the intensive care unit for cardiac specialists. The Intensive Care Unit is an intensive care unit for patients with respiratory, circulatory, metabolic and other systemic failures in medical and surgical departments, and provides intensive systemic management of their respiratory, circulatory, metabolic and other functions. A central monitoring station is available for direct observation of all monitored beds. The ICU is mainly for: (1) patients with severe trauma, post major surgery and those who must be monitored and supported continuously and closely for vital indicators; (2) those who need cardiopulmonary resuscitation; (3) those who have an organ (including heart, brain, lung, liver and kidney) failure or multiple organ failure; (4) patients with severe shock, sepsis and poisoning; (5) those who need monitoring and enhanced treatment before and after organ transplantation. (5) Patients who need monitoring and intensive treatment before and after organ transplantation. After their condition improves, they are transferred back to the general ward. In our spine surgery specialty, many times cervical spine surgery patients need to stay in the ICU for a day or two after surgery, and many older patients, or those who have lost too much blood during surgery, can also be observed inside for a day or two, which is beneficial to the life and health of the patient and reduces the burden on the surgeon after surgery.
