For epidural anesthesia, pillows are not allowed after surgery. Pillows are not allowed after anesthesia for highly dangerous and extensive surgeries. 1. In major surgery, such as high-risk and wide-ranging surgery, anesthesia drugs are usually used, usually for lumbar anesthesia or epidural anesthesia or lumbar-hard joint anesthesia, and at this time it is not recommended to use pillows after surgery, because after anesthesia for the surgery, the pressure within the cerebrospinal fluid is still unbalanced, and at this time if pillows are used, it may lead to the patient’s nausea, vomiting, dizziness and so on. 2. It is generally recommended that patients can have pillows after 24 hours of anesthesia. At the same time, the changes of patients’ vital signs, such as blood pressure, pulse, heart rate, oxygen saturation, etc., should be monitored after surgery. If the patient experiences discomfort, the doctor should be informed promptly to avoid any adverse effects. The patient can consult the doctor whether the pillow can be used after the surgery or before the surgery.
