Many authors have assumed that decreased thyroid hormones levels occurring during cardiopulmonary bypass should be preoperatively balanced by T4 or T3 supplementation. The rationale for this undertaking is prevention of negative effects from depressed cardiac output, perfusion pressure, stroke volume, and contractility intra- and postoperatively [8, 9].
Nonetheless, as pointed out previously, this matter is so intriguing that some authors, such as Velissaris et al. [10], have advocated that a reduction in thyroid hormone levels might consist of an organic adaptive process of reduced catabolism rather than a true hypothyroid state. The basis for this theory was the association between low free T3 levels and high global oxygen consumption (Fig. 31.10) [10].
