Brief Answer:
34°C best with risk benefit assessment to patient.

Detailed Answer:

Thanks for writing in to us.

Hypothermia (32–35 °C) during cardiopulmonary surgery has well-documented neuroprotective benefits. Evidence suggests that hypothermia improves neurologic outcome even when induced after a cerebral ischemic event. Rewarming must proceed slowly, and the clinician may consider weaning at temperatures slightly below 37 °C in patients at high risk of an ischemic (stroke) event.

Hyperthermia—even if mild—can exacerbate any neurologic injury that occurs during surgery, so it is critical to avoid overheating of the brain during rewarming. Finally, physicians should continue temperature management into the postoperative period.

As per a group of researchers, as there is some raise in temperature after surgery, weaning is better at 34 degrees and this decreases the onset of postoperative cognitive deficits. It is important to note that this lower post-surgery temperature has the potential to cause hemodynamic instability or coagulopathy; the risks and benefits must therefore be weighed for each individual patient.

Hope your query is answered.
