Perioperative hypothermia may be due to direct anesthetic inhibition of thermoregulation, decreased metabolism and loss of heat to the cold environment of operating rooms, even with active warming. When it is inadvertent, it may be associated to several complications, but when adequately indicated, it may protect vital organs such as central nervous system and heart. Normothermia decreases undesirable hypothermia effects, being warming the most effective preventive method. Active or passive warming approaches should be adopted and muscle shivering should be adequately treated to prevent discomfort and increased metabolic demand.

“…Luz et al compared acid-base balances in patients at normothermia (37°C) and mild/moderate hypothermia (35-33°C). They then evaluated parameters such as pH, arterial bicarbonate and BDs, and no statistically significant differences was found in these parameters [ 15 ] . Similarly, no significant differences in blood gas values were observed in our study.…”

Objectives Stroke is an important cause of mortality and morbidity in surgery. In the present study, we examined the cerebral oximetry values of patients with carotid artery stenosis who did not present surgical indications and those who did not present carotid artery stenosis in coronary artery bypass grafting (CABG) surgery by comparing their cerebral oximetry values with cerebrovascular disease (CVD). Methods Between January and May 2014, 40 patients who underwent isolated CABG were included in the study. Cerebral oximetry probes were placed prior to induction of anesthesia. Cerebral oximetry values were recorded before induction, in the pump (cardiopulmonary bypass) inlet period, in the post-clamp period, in the pump outlet period, and in the intensive care unit and neurological complications. Results There was no difference between the groups in terms of demographic data and routine follow-up parameters. Intraoperative surgical data and early postoperative results were similar in both groups. When comparing the groups, there were no statistically significant results in cerebral oximetry values and CVD development. Only one patient in group 2 had postoperative CVD and this patient was discharged from the hospital with right hemiplegia. Mean arterial pressure (MAP)levels were significantly higher in Group 2 ( P <0.05). Conclusion The follow-up of cerebral perfusion with a method like near-infrared spectroscopy (NIRS) will ensure that MAP is adjusted with interventions that will be made according to changes in NIRS. Thus, it will be possible to avoid unnecessary medication and flow-rate increase with cerebral oxygen saturation (rSO 2 ) follow-up.

“…Extracorporeal circulation (ECC) might cause lung damage during the postoperative period of cardiac surgery, thus contributing to the mortality of patients due to physiological modification of the acid-base and metabolic balance, increased inflammatory response, increased vascular permeability, increased pulmonary shunt or reduced lung compliance and gas exchange. (1)(2)(3) Most patients subjected to myocardial revascularization (MR) exhibit a reduction in lung compliance, whereas approximately one-third exhibit increased airway resistance. In half of patients presenting with comorbidities, the index of gas exchange decreases by 50%.…”

“…Appropriate ventilation during and after surgery might improve the patient's safety and could minimize metabolic and ventilatory repercussions that appear within a short period of time. (1,9,10) Most of the studies that report physiological alterations during the transportation of severe patients were observational and associated such alterations with higher morbidity during stays in closed units. (11)(12)(13) The degree of arterial gas alteration during transportation of potentially severe patients using ventilatory methods (either by bag and mask ventilation or mechanical ventilator) has not been quantified; this is a dynamic process that requires appropriate monitoring, coordination, communication and equipment.…”
