Therapeutic hypothermia

  1. 1. Mild Therapeutic Hypothermia javier benitez (@jvrbntz) In 5 slides or less...
  2. 2. Case Presentation● 46 yo woman w PMH of HTN p/w witnessed OHCA one hour ago, she has ROSC after shocked when in VF rhythm, but has no return of consciousness. Bystanders state she was complaining of chest pain.● Vital signs are within normal limits. PE is normal wtih no signs of trauma.● She is sedated and intubated, IV access, ECG does not show signs of ischemia, trops, glucose, electrolytes, other labs, and CXR are normal
  3. 3. Things to Consider● Whats the goal temperature in therapeutic hypothermia?● List the phases of therapeutic hypothermia● What are the mechanisms by which therapeutic hypothermia exerts neuroprotection?
  4. 4. ● The temperature goal is around 32o-34o C● Phases of therapeutic hypothermia – Induction: onset, rate, and target temperature – Maintenance: duration and temperature control – Rewarming: different approaches, but slow rate● Neuroprotection: – Decreases brain metabolism – Slows down cell death – Reduction of free radical production – Decrease inflammatory response – Protects the blood brain barrier
