Small observational series of post-CABG thermoregulation; leaves open whether vasoconstriction or lactate patterns warrant targeted interventions.

Residual hypothermia after cardiac surgery triggers thermoregulatory responses that cause a transient oxygen supply and uptake mismatch in skeletal muscles.
Licker et al. (1996) conducted an observational in Post-coronary artery bypass graft surgery (n=13). Coronary artery bypass graft surgery with residual hypothermia was evaluated on Thermoregulatory and metabolic responses (cutaneous vasoconstriction, muscular hyperactivity, blood gases, lactate). Residual hypothermia following cardiac surgery elicited thermoregulatory responses associated with transient O2 supply/uptake mismatch within skeletal muscles, including elevated O2 extraction (56%).
