The sequelae of craniotomy for brain hemorrhage mainly include postoperative pneumothorax, postoperative infection, postoperative cerebrospinal fluid leakage, postoperative cerebral infarction, postoperative hydrocephalus, postoperative epilepsy, postoperative coagulation abnormalities and postoperative electrolyte disorders. For patients who develop post-operative sequelae of craniotomy, active symptomatic management is required. If postoperative infection occurs, extraventricular drainage is required to drain the infected cerebrospinal fluid outside the body, and sensitive antibiotics are selected for treatment based on the results of cerebrospinal fluid culture. In the case of postoperative epilepsy, oral antiepileptic drugs are routinely required for treatment. In the case of postoperative water-electrolyte disorders, active correction of electrolyte levels is required, along with dynamic rechecking. If it is a postoperative coagulation abnormality, symptomatic treatment such as supplementation of coagulation factors may be required.
