The edema phase of the brain stem generally lasts for two to three weeks, with the peak of swelling occurring around seven to ten days. For some patients, the swelling completely subsides nearly a month later. Only after the peak of the swelling has passed can patients be out of life-threatening danger. As the swelling gradually subsides, the patient's consciousness, vital signs, limb movements, eating, and other symptoms will also gradually improve. Once patients get through the swelling phase, we can start early bedside rehabilitation as soon as possible. In addition to using some drugs that nourish brain nerves, passive limb movements, proper limb positioning, early exercise, and acupuncture can all be started early to accelerate the patient's early rehabilitation and prevent complications such as muscle atrophy, relaxation, and dependent pneumonia, which can be improved early on.
