Care of renal cyst decompression surgery: First, because renal cyst decompression surgery is usually performed by general anesthesia or epidural cavity block anesthesia, the patient should be placed in a flat position with pillow for 6-8 hours, while oxygen is given to the patient, and attention is paid to whether the patient is conscious or not, and cardiac monitoring is given to monitor the patient’s blood pressure and heart rate so as to determine whether there is bleeding or even hemorrhage after surgery. Secondly, a single antibiotic treatment can be used to prevent infection after renal cyst decompression surgery. Thirdly, for the care of drainage tube, the drainage tube is usually removed in 2-3 days after surgery, and we should pay attention to the drainage flow of the drainage tube and whether the drainage tube is smooth, and it should be fixed in place to avoid falling off. Fourth, pay attention to routine care, such as wound cleaning. Fifth, it is recommended that patients can be properly active two days after surgery, and finally, health education on renal cyst can be given to patients.
