Fig 1 (a) Postoperative blood glucose levels (glucose-insulin-potassium [Gik], circles, n = 20; control, squares, n = 20). Blood glucose levels were lower (p < 0.001) and better maintained within the targeted range in the Gik group than in the control group. (b) Postoperative blood lactate levels (Gik, n = 20, circles; control, boxes, n = 20). The control group had higher blood lactate levels compared with the Gik group (p = 0.016), and the lactate levels normalized faster in the Gik group (p = 0.046). Values are presented as a median and 25th and 75th percentiles. (ICU = intensive care unit.)

Fig 2 (a) Perioperative cardiac indices (glucose-insulin-potassium [Gik], circles, n = 20; control, squares, n = 20). Cardiac indices were higher in the Gik group than in the control group after perfusion (p = 0.053) and after 8 hours stay in the intensive care unit (ICU [p = 0.062]). Values are presented as median and 25th and 75th percentiles. (b) Perioperative systemic vascular resistance indices (Gik, circles, n = 20, control, squares, n = 20). There were no significant differences between the groups with regard to these variables. Values are presented as median and 25th and 75th percentiles. (CI = cardiac index; ICU 0h = after admission to intensive care unit; ICU 4h = after 4 hours intensive care unit stay; ICU 8h = after 8 hours intensive care unit stay; 1st pod. = first postoperative morning; SVRI = systemic vascular resistance index.)

Fig 3 Postoperative plasma potassium levels (glucose-insulin-potassium [GIK], circles, n = 20; control, squares, n = 20). Plasma potassium levels were lower in the GIK group than in the control group after the admission into the intensive care unit (p < 0.001). Values are presented as median and 25th and 75th percentiles. (ICU = intensive care unit.)
