The main points of post-operative care for lumbar anaesthesia include the following: 1. After returning to the ward, the patient should lie flat on the pillow for 6 hours and be advised not to sit or stand; 2. Before the anaesthetic effect disappears, pay attention to the patient’s blood pressure, pulse and respiration, pay attention to the plane of anaesthesia and report immediately to the nurse or doctor if there is respiratory depression or change in blood pressure and pulse; 3. Pay attention to the time of urination, those who cannot urinate on their own 6-8 hours after surgery should be induced to urinate, and those who are ineffective should be given catheterisation; 4. If there are symptoms such as headache, lumbago and vomiting after surgery, symptomatic treatment can be given; 5. Fasting for 6 hours after surgery and giving diet as prescribed by the doctor after 6 hours.
