  21. 21. Potential treatments of ICH Stopping or slowing the initial bleeding; Removing blood from the parenchyma or ventricles; Management of complications of blood in the brain, including increased ICP and decreased CPP Good clinical practice: Management of airways, oxygenation, circulation, glucose level, fever, nutrition, and DVT prevention. Lack of definitive randomized trials of either medical or surgical therapies for ICH, great variability in care

  30. 30. The STICH results do not significantly change current practice. Patients with a subcortical or cerebellar hematoma at least 3 cm and impaired consciousness should be operated on.operated on. Comatose patients (GCS 8) with ICH in the basal ganglia or thalamus very unlikely benefit from clot removal. Minimally invasive methods may be useful if done early after ICH onset, but control of hemostasis may be difficult.
  31. 31. To establish whether earlier surgical evacuation of lobar ICH will improve outcome compared initial conservative treatment. To better define the indications for early surgery. This will overcome two of the criticisms of STICH (timing was too late and sometimes location was too deep).
  32. 32. Inclusion: Spontaneous lobar ICH on CT Scan Patient randomised within 48 hours of ictusPatient randomised within 48 hours of ictus Surgeon is in equipoise Best EYE score of 2 or more & M5/M6 Volume of haematoma 10 - 100ml
  33. 33. Exclusion: Aneurysm, tumour, trauma, angiographically provenAVM . Brain stem / cerebellar haemorrhage. Intraventricular haemorrhage , Hydrocephalus . Surgery cannot be performed within 12 hours. Unreversed clotting or coagulation problems. Severe pre-existing physical or mental disability or severe co- morbidity
  34. 34. Patient randomized within 48 hours of ictus . If randomized to early surgery this should be undertaken within 12 hours. CT scan at about five days (+/- 2 days) .CT scan at about five days (+/- 2 days) . 600 patients will be recruited 30 months. FU will take 6 months with analysis and reporting taking 1 year. Outcome will be measured at 6 months via a postal questionnaire incl. the GOS, MRS, EuroQol and Barthel.

  37. 37. Emergency diagnosis and assessment of ICH and its causes Rapid neuroimaging with CT or MRI is recommended to distinguish ischemic stroke from ICH. Class I, Level A Medical treatment for ICH Patients with a severe coagulation factor deficiency or severe thrombocytopenia should receive appropriate factor replacement therapy or platelets, respectively. Class I, Level C
  38. 38. Hemostasis/antiplatelets/DV T prophylaxis Patients with ICH whose INR is elevated due to OAC should have their warfarin withheld, receive therapy to replace vitamin K–dependent factors and correct the INR, and receive intravenous vitamin K. Class I, Level C K. Patients with ICH should have intermittent pneumatic compression for prevention of venous thromboembolism in addition to elastic stockings. Class I, Level B
  39. 39. Inpatient management and prevention of secondary brain injury General monitoring Initial monitoring andInitial monitoring and management of ICH patients should take place in an intensive care unit, preferably one with physician and nursing neuroscience intensive care expertise. Class I, Level B
  40. 40. Management of glucose Glucose should be monitored and normoglycemia is recommended Class I, Level C Seizures and antiepileptic drugs Patients with clinical seizures should be Class I, Level A antiepileptic drugs seizures should be treated with antiepileptic drugs. Patients with a change in mental status who are found to have electrographic seizures on EEG should be treated with antiepileptic drugs Class I, Level C
  41. 41. Patients with cerebellar hemorrhage who are deteriorating neurologically or who Procedures/surgery—clot removal neurologically or who have brainstem compression and/or hydrocephalus from ventricular obstruction should undergo surgical removal of the hemorrhage as soon as possible. Class I, Level B
  42. 42. Prevention of recurrent ICH After the acute ICH, absent medical contraindications, BP should be well controlled, particularly for Class I, Level A particularly for patients with ICH location typical of hypertensive vasculopathy.
  43. 43. (Class II a; Level of Evidence: B). (Class II b; Level of Evidence: B) CT angiography, CT venography, contrast- enhanced CT, CEMRI, MRA & CT angiography and contrast- enhanced CT may be considered to help identifyenhanced CT, CEMRI, MRA & MRV can be useful to evaluate for underlying structural lesions when there is clinical or radiological suspicion considered to help identify patients at risk for hematoma expansion
  44. 44. (ClassIIa; Level of Evidence: B) PCCs have not shownimproved outcome comparedwith FFP but may have fewer complicationscompared with FFPand are reasonable to consider as an alternative to FFP (Class IIb; Level of Evidence: B) The usefulness of platelet transfusions in ICH patients with a history of antiplatelet use is unclearand is considered investigational After documentation of cessation of bleeding, low-dose subcutaneous low-molecular-weight heparin or unfractionated heparin may beconsidered for prevention of venous thromboembolism in patients with lack of mobility after 1 to 4 days from onset
  45. 45. (ClassIII; Level of Evidence: A) rFVIIa does not replaceall clottingfactors, and although the INR may be lowered, clottingmay notbe restored in vivo; therefore, rFVIIa is not routinely recommendedas a sole agent for OAC reversal in ICH Although rFVIIa can limit the extent of hematoma expansion in noncoagulopathicICH patients, there is an increase in thromboembolicrisk with rFVIIa and no clear clinical benefit in unselectedpatients.Thus rFVIIa is not recommended in unselected patients
  46. 46. In patients presenting with a systolic BP of 150 to 220 mmHg, acute lowering of systolicBP to 140 mm Hg is probably safe(Class IIa; Level of Evidence:B). (New recommendation) If SBP is 200 mm Hg or MAP is 150 mm Hg Aggressive reduction and frequent monitoring (5 minutes) If SBP is 180 mm Hg or MAP is 130 mm Hg with elevated ICP Monitoring ICP Reducing BP to keep CPP >60 mm Hg If SBP is 180 mm Hg or MAP is 130 mm Hg no ICP issues, Modest reduction of BP (~MAP of 110/BP 160/90) Using intermittent or continuous IV meds Evaluate every 15 minutes.
  47. 47. (Class II a; Level of Evidence:B) (Class III; Level of Evidence:B) Continuous EEG monitoring is probably Prophylactic anticonvulsantmonitoring is probably indicated inICH patients with depressed mental status out of proportion to the degree of brain injury anticonvulsant medication should not be used
  48. 48. (Class II a;Level of Evidence: B) Ventricular drainage as treatment for hydrocephalus isreasonablein patients with decreased level of consciousness (Class II b; Level of Evidence:C) Patients with a GCS score of 8, those with clinical evidenceof transtentorial herniation, or those with significant IVHor hydrocephalus might be considered for ICP monitoring andtreatment.for ICP monitoring andtreatment. (Class IIb; Level of Evidence:B) Although intraventricular administration of rtPA in IVH appears to have a fairly low complicationrate, efficacy and safety of this treatment is uncertain andis considered investigational
  49. 49. (Class IIb; Level of Evidence: B) (Class IIb; Level of Evidence: C) For patients presentingwith lobar clots >30 mL and within1 cm of the surface, evacuationof For most patients with ICH, the usefulness of surgery isuncertain . Specific exceptions to thissurface, evacuationof supratentorial ICH by standard craniotomy might be considered Specific exceptions to this recommendation have been described. The effectiveness of minimally invasive clotevacuation utilizing either stereotactic or endoscopic aspirationwith or without thrombolytic usage is uncertain and is consideredinvestigational
  50. 50. (ClassIII; Level of Evidence: B) (Class III; Level ofEvidence: C) Although theoretically attractive, no clear evidence atpresentindicates that ultra-early removal of Initial treatmentof these patients with ventricular drainage alone rather than surgical evacuation is notultra-early removal of supratentorialICH improves functional outcome or mortality rate.Very early craniotomymay be harmful due to increased risk of recurrentbleeding surgical evacuation is not recommended
  51. 51. (Class IIa; Level of Evidence: B) Aggressive full care early after ICH onset and postponementof new DNR orders until at least the second full day of hospitalizationisleast the second full day of hospitalizationis probably recommended
  52. 52. (Class II a; Level of Evidence:B) Risk factors for recurrence: lobarlocation of the initial ICH, older age, ongoing anticoagulation,presence of the apolipoprotein E 2 or 4 alleles, and greaterthe apolipoprotein E 2 or 4 alleles, and greater number of microbleeds on MRI Afterthe acute ICH period, a goal target of a normal BPof <140/90(<130/80 if diabetes or chronic kidney disease)is reasonable Avoidance of long-term anticoagulation as treatment for nonvalvularatrial fibrillation is probably recommended after spontaneouslobar ICH because of the relatively high risk of recurrence
  53. 53. (Class IIa;Level of Evidence: B) Avoidance of heavy alcohol use can be beneficial (Class IIb; Level of Evidence:B) (Class IIb; Level of Evidence:C) Anticoagulation after nonlobarICH and antiplatelet therapy after all ICH might be considered, particularly when there are definite indications for these agents There is insufficient datato recommendrestrictions on use of statin agents or physicalor sexual activity
