Endovascular cooling and rewarming is reported to be faster (1.46°C/h, [47]  1.59°C/h [44] ) and better at maintaining target temperature. These devices are generally placed in the femoral vein and are associated with a low rate of complications. Guluma et al reported endovascular cooling in conjunction with buspirone and surface warming allowed targeted temperature management (TTM) without shivering and avoided the need for chemical paralysis. [44] Extremely tight temperature control was also documented. [44] Thus, intravascular cooling allows:

  • Most rapid cooling

  • Tightest control of target temperature

  • Minimization of shivering and possible increase in the patient’s comfort as cutaneous warming is permitted

  • Opportunity to avoid need for chemical paralysis of the patient
