Recommendations for surgical methods 1, Class I recommendation: those with cerebellar hemorrhage >3mL should be operated as soon as possible if neurological function continues to deteriorate or hydrocephalus is caused by brainstem compression and/or ventricular obstruction (Class I recommendation, Level of Evidence B). 2, Class II recommendations: ① within 72h after the onset of the disease, stereotactic injection of urokinase into the hematoma cavity can significantly reduce the hematoma volume and reduce the morbidity and mortality rate, but it is prone to cause rebleeding, and the prognosis has not been improved, so it is not yet possible to determine the effectiveness of this treatment (Class IIb recommendation, Level of Evidence B); ② theoretically, minimally invasive blood clot aspiration with various mechanical devices and/or endoscopy is feasible, but its (ii) Minimally invasive clot aspiration with various mechanical devices and/or endoscopes is theoretically feasible, but its effectiveness needs to be further tested in clinical trials (Class IIb, Level of Evidence B); (iii) Lobar hemorrhage within 1 cm from the surface of the brain can be considered for removal of supratentorial hematomas by conventional craniotomy (Class IIb, Level of Evidence B). 3. Class III recommendation: Removal of supratentorial ICH by conventional craniotomy within 96h after onset is not recommended (Class III recommendation, Level of Evidence A), with the exception of lobar hemorrhage within 1cm from the surface of the brain. Recommendations for timing of surgery 1. Class II recommendation: there is no clear evidence that ultra-early craniotomy improves prognosis or reduces morbidity and mortality. There is more evidence to support minimally invasive surgical removal of ICH within 12 h, but the number of patients treated within this time window is too small (Class IIb recommendation, level of evidence B). Ultra-early craniotomy may increase the risk of rebleeding (Class IIb recommendation, Level of evidence B). Class III: It is fairly safe to say that prolonged hematoma removal with craniotomy has a very limited role. In comatose patients with deep hemorrhage, the actual efficacy of craniotomy for hematoma removal is even worse, so it is not recommended (Class III recommendation, Level of Evidence A). Recommendations for decompressive craniectomy Class II recommendation: It is uncertain whether decompressive craniectomy improves the prognosis of ICH because there is too little clinical trial data (Class IIb recommendation, Level of Evidence C). Recommendations for discontinuation of therapy 1. Class II: It is recommended that, unless the patient has a “Do Not Resuscitate” (DNR) statement prior to the onset of ICH, full and aggressive treatment be seriously considered within 24 h of the onset of ICH (Class IIb, Level of Evidence B). Moreover, in all cases, physicians and nurses should remember that the DNR applies only in cases of cardiopulmonary arrest; otherwise, patients should be treated with all reasonable medical and surgical measures. Recommendations for the prevention of recurrent cerebral hemorrhage 2. Class I recommendations: ① Outpatient treatment of hypertensive disorders is the most important measure to reduce the risk of ICH: this is also true for recurrent ICH (Class I recommendation, Level of Evidence A); ② Cigarette smoking, alcohol abuse and cocaine abuse are risk factors for ICH: it is recommended that these behaviors be discontinued in order to prevent recurrence of ICH (Class I recommendation, Level of Evidence B).
