When the patient wakes up after heart surgery, he or she is already in the intensive care unit. The patient will feel unconscious, have the feeling of wanting to move, and will also have a feeling of thirst. Due to the general anesthesia, the patient has not recovered his or her voluntary respiratory function at first and needs a ventilator to help him or her breathe. There is a tube in the mouth called “tracheal intubation”, which can be very uncomfortable, but most of them can tolerate it. In addition, in the early postoperative period, patients cannot urinate on their own, and a catheter is placed in the urethra to drain the urine produced. It is normal for the catheter to cause a little irritation to the urethra, causing the patient to feel a sense of holding and wanting to urinate. This is normal. The catheter can be removed when the patient can control urination on his own. Also, when the patient wakes up, you will be immediately noticed by the medical staff and communicate with you, such as calling your name, opening your eyes, nodding your head, shaking your hand, lifting your leg, etc. If you can hear you clearly, please ask the patient to shake your hand. If you can hear clearly, please try to cooperate and respond, so that we can make an accurate judgment of your state of consciousness. The discomfort mentioned above will disappear soon and is an integral part of the whole treatment process. Many patients are concerned about the pain of the incision after they wake up from anesthesia. Please rest assured that you and your family will be treated according to the patient’s pain level, and if necessary, continuous analgesic treatment (analgesic pump) can be administered to reduce the patient’s postoperative pain discomfort.
