Though TTM is ubiquitously used in the neuro-intensive care unit, there is limited experience with the use of TTM after intracerebral hemorrhage (ICH), the most devastating type of stroke. TTM may be a an intervention to improve patient outcomes. This trial addresses the safety and tolerability of a protocol of ultra-early TTM after ICH/IPH and may be the basis for future larger clinical trials.

Primary Outcome Measures:
  • Severe adverse events (SAEs) [ Time Frame: 90 days ]
    The primary outcome measures will be: a) the frequency of adverse events (AEs) that will be possibly or probably related to treatment. AEs will be assessed up to 15-days after admission or discharge if earlier, and b) the frequency of severe adverse events (SAEs) that will be possibly and probably related to treatment.

Secondary Outcome Measures:
  • In-hospital neurological deterioration between day 0-7 [ Time Frame: 7 days ]
    Decrease in GCS in ≥2 points or increase in the NIHSS ≥4 points

  • Functional outcome [ Time Frame: Discharge and 90 days ]
    Modified Rankin Scale at discharge and 90-days.

  • Hematoma growth [ Time Frame: 24 hours ]
    Absolute change in hematoma between baseline and 24 hours CT-scan and new or absolute change in IVH between baseline and 24 hours CT-scan

  • Cerebral edema [ Time Frame: 24, 48,72, and 168-hours ]
    The absolute change in cerebral edema and the relative change in cerebral edema (absolute edema/absolute ICH volume unit less ratio)

Estimated Enrollment: 50
Study Start Date: January 2013
Estimated Study Completion Date: June 2016
Primary Completion Date: June 2015 (Final data collection date for primary outcome measure)

Other: Hypothermia
72 hours of targeted temperature management to achieve hypothermia (32-34°C)

Detailed Description:
Morbidity and mortality from intra-cerebral/intra-parenchymal hemorrhage (ICH/IPH) are important public health problems. As the most common etiology of ICH/IPH is hypertension, this places a large proportion of the population at risk. In 2011 The American Heart Association (AHA) estimated that in the US, there were 610,000 new stroke cases of which 10% were ICHs, and many required long-term health care. ICH/IPH is associated with the highest morbidity and mortality and only 20% of patients regain functional independence. Temperature modulation to hypothermia (T, 32-34°C) has been associated with modulation of physiopathologic processes associated with inflammatory activation and degradation of blood-brain barrier after all types of brain injury. Currently, there are no therapies to specifically target ICH/IPH. To this end, novel strategies that go beyond control of glucose, blood pressure, and intra-cranial pressure, aimed at reducing the enlargement of the hematoma and "swelling" surrounding it, could be "the new frontier in the management of ICH/IPH". Since the early resuscitation phase in the Neuro-ICU represents the greatest opportunity for impact on clinical outcome after ICH/IPH, it also appears to be the most promising window of opportunity to demonstrate a benefit when investigating novel therapies.
