Care of laparoscopic renal cyst decortication and decompression. First, laparoscopic renal cyst decompression is a general anesthesia operation. After the surgery, the patient should be asked to lie down with the head tilted to the side to prevent vomiting and asphyxiation. Secondly, because it is a general anesthesia surgery, the patient’s vital signs, such as blood pressure, heart rate and oxygen saturation, should be monitored by cardiac monitoring after the surgery. And after decompression surgery, patients may bleed, so we should pay close attention to the blood pressure and heart rate indicators, and pay attention to whether there is blood leakage from the wound. Thirdly, patients undergoing laparoscopic decompression require postoperative fasting, and after ventilation, they can eat fluids appropriately, and then go over to ordinary diet. There are also renal cyst decompression surgery patients because the laparoscopic surgery, so the process of surgery to pump into the stomach to form an artificial pneumoperitoneum. So we should pay attention to the patient after surgery, whether the patient has subcutaneous pneumonia. Fourth, because laparoscopic renal cyst decompression may be combined with infection, we should pay attention to the patient’s body temperature, fever can be given physical cooling and anti-infection treatment.
