Ovarian malignant tumor is one of the common malignant tumors of female reproductive organs, which poses a serious threat to women’s lives. Due to the complicated embryonic development, tissue anatomy and endocrine function of ovary and atypical early symptoms, it is quite difficult to identify the tissue type, benign and malignant of ovarian tumor before surgery. Surgery is the main treatment method, so how to take good care of ovarian cancer after surgery? The following are the postoperative care methods of ovarian cancer. 1. Patients with ovarian cancer must pay attention to monitoring patients’ vital signs after surgery, including their blood pressure and pulse rate. Before the patient wakes up, the patient should be kept in a lying position and the patient’s head should be tilted to the side to avoid saliva and vomit from entering the patient’s respiratory tract and causing infection. 2. If the patient with ovarian cancer is under hard external anesthesia or lumbar anesthesia, he/she should lie down for 4-6 hours after surgery to avoid painful symptoms due to increased intracranial pressure in the head. 3. After removal of urinary catheter, ovarian cancer patients should pay attention to replenish water to avoid urinary retention. 4. After surgery, ovarian cancer patients should pay attention to monitor the urinary catheter, vaginal drainage tube and abdominal drainage tube and record the drainage flow and color of drainage to avoid folding the catheter, and if any abnormality occurs, notify the doctor and deal with it immediately.
