The patient came out of the operating room and the doctor said, “The operation was a success!” . When the family hears these words, they feel much more secure. Is “successful surgery” the same as “everything is fine”? There is no doubt that surgery is an important part of the entire treatment process, but it is not the whole process. After the patient comes out of the operating room, the ward needs to monitor blood pressure, respiration, heart rate, drainage, urine volume and many other indicators. If the doctor can carefully observe the abnormal changes of these indicators, he or she can promptly deal with them until the patient’s general condition is completely stable, which is what we hear as “passing the danger period”. Rehabilitation training: orthopedic surgery is to restore or preserve the function of the limb as much as possible, if the limb does not dare to move for a long time, the muscles will gradually atrophy and the joints will become stiff. Therefore, some time after the surgery, the doctor will help the patient to make a personalized rehabilitation plan to help the patient to rehabilitate, such as: how to move the limb, what changes will occur during the activity, what reactions are normal, when to go to the hospital for review, etc.
