Forced-Air Warming Decreases Vasodilator Requirement After Coronary Artery Bypass Surgery

Thermogenic effect of amino acids not demonstrated in heart surgery with cardiopulmonary bypass

“…Several methods are used to ameliorate hypothermia at the end of heart surgery (5), mainly focused on minimizing external heat loss (6). In patients undergoing abdominal surgery, a thermogenic effect of an infusion of amino acids during anaesthesia has been documented, resulting in reduced hypothermia after surgery (7, 8).…”

Comparison of fast versus slow rewarming following acute moderate hypothermia in rats

“…In both study groups, at the beginning of the rewarming process and up to 31 °C body temperature, no significant changes in the various physiological parameters were recorded (there was only a slight transient decrease of the MAP in the fast rewarming group). The explanation for these findings is a result of the swift transitional state between vasoconstriction and vasodilatation found to occur during rewarming (37). On reaching a body temperature of approximately 31 °C and thereafter, in the fast rewarming group, heart rate increased acutely, possibly due to a direct catecholamine response (38) (not measured in this study), and as a compensatory response to massive vasodilatation with a significant decrease of the SVR (14,15).…”

Efectos De Diferentes Métodos De Calentamiento Utilizados en El Perioperatorio en El Adulto

“…El calentamiento cutáneo agresivo esta asociado a una disminución de los requerimientos en la terapia vasodilatadora después de la cirugía (25,26). También se encontró que el calentamiento disminuyó los requerimientos de vasodilatadores en un 13% (22) y la disminución estadísticamente significativa en el uso de antibióticos postoperatorios de un 15,9 a un 6,5% (13).…”
