The reasons for going to the pillow and lying flat after anesthesia are as follows: 1. Intraspinal anesthesia is commonly known as hemi-anesthesia, because the anesthesia puncture will puncture the dura mater and cerebrospinal fluid will flow out from the puncture point, resulting in lower intracranial pressure, so the patient will have a significant headache and even neurological symptoms. In order to avoid a large amount of cerebrospinal fluid outflow, it is necessary to go to the pillow and lie down to promote the healing of the dural break, but intravertebral anesthesia is also divided into epidural anesthesia and subarachnoid block anesthesia, epidural anesthesia, if operated smoothly, will not puncture the dural membrane, so theoretically epidural anesthesia does not need to go to the pillow and lie down. Because of the unstable consciousness of the patient after general anesthesia, sometimes awake, sometimes drowsy, go to the pillow to lie flat, and tilt the head to the side is safer, can avoid the throat secretions into the airway caused by asphyxiation. In addition, the nursing position after general anesthesia should be decided according to the type of surgery and anesthesia, most patients should be in a semi-recumbent position with the upper body elevated after general anesthesia, and whether or not to sleep on pillows depends on whether sleeping on pillows will obstruct the airway opening, most people are more comfortable with thin pillows. In clinical practice, patients entering the ward after surgery need to strictly implement postoperative care routines and nursing procedures.
