Introduction
A patient who has undergone craniotomy can typically pass the critical period in about 7 days. Within the first 24 hours after surgery, close observation is primarily conducted for any signs of bleeding. If no bleeding occurs, the likelihood of subsequent hemorrhage is significantly reduced. Around 5 days post-surgery, cerebral edema gradually reaches its peak, necessitating close monitoring of intracranial pressure and brain tissue compression. Approximately 7 days after surgery, if infection-related symptoms such as high fever and headache are under control, the patient's condition is considered relatively stable.
Under normal circumstances, most patients who undergo craniotomy can get through the critical period within about 7 days. If there are any concerns, it is recommended to seek medical advice in advance. Detailed analysis is as follows:
For a standard craniotomy, patients usually pass through the critical period within approximately 7 days. During the first 24 hours after surgery, close monitoring for any signs of bleeding is essential. If no bleeding occurs, the likelihood of rebleeding becomes very low. Around the fifth day post-surgery, brain edema typically reaches its peak, so close monitoring of intracranial pressure and brain tissue compression is necessary. If symptoms of infection, such as high fever and headache, are under control by about the seventh day after surgery, the patient's condition is considered relatively stable. If cerebral edema gradually subsides, the patient's condition becomes increasingly stable, and no complications such as bleeding or infection occur, then the critical period is considered to have passed.
However, for the small number of more complex and risky craniotomies, such as those caused by ruptured cerebral aneurysms, ruptured cerebral arteriovenous malformations, or hypertensive intracerebral hemorrhage, the critical period may be longer, requiring extended observation and management of potential complications. This is especially true when patients present with coma or dilated pupils before surgery, require reoperation due to postoperative rebleeding, or develop complications such as coma or severe cerebral edema after surgery.
During the critical period, patients should be kept in a quiet and comfortable environment to minimize external stimuli. Regular turning is necessary to prevent deep vein thrombosis in the lower limbs and to avoid pressure ulcers, particularly in unconscious patients.
