The aim of this prospective study was to determine whether the preoperative oral intake of carbohydrate-rich drinks by patients undergoing a coronary artery bypass graft attenuates postoperative insulin requirements, improves postoperative patient discomfort, provides inotropic support, shortens the length of the ICU stay, and shortens the duration of postoperative mechanical ventilation.
Materials and methods:This randomized prospective clinical study included 152 patients with coronary artery disease who were divided into 4 groups. Carbohydrates were administered to 3 groups at different hours and doses before operation. The fourth group had an 8-h preoperative fasting period. The inotropic and vasopressor requirements, ventilation time, and ICU stay time were recorded for all of the groups. Patient wellbeing, mouth dryness, hunger, anxiety, and nausea were assessed using VAS scores of 1-10.Results: Mouth dryness and hunger were significantly higher in the control group (P = 0.03, P = 0.02). The increase in blood glucose level was significantly higher in the control group (P = 0.04). The exogenous insulin requirement was significantly higher in the control group than in the other groups (P = 0.04).
Conclusion:The administration of carbohydrates before elective cardiac surgery reduced insulin resistance. Based on the VAS scores, the intake of carbohydrates reduced mouth dryness and hunger. Overall, preoperative oral carbohydrate treatments can improve the postoperative outcomes of coronary artery bypass graft surgeries.
Coronary artery bypass grafting operations in patients with an atherosclerotic ascending aorta are still associated with an increased risk of cerebral embolism and mortality despite previously described techniques. Here we present an alternative technique for the construction of a proximal anastomosis avoiding aortic clamping and deep hypothermic circulatory arrest.
ObjectiveAcute kidney injury after cardiac surgery is associated with mortality and
morbidity. Therefore, strategies to prevent acute kidney injury are very
important. The aim of this placebo-controlled randomized double-blind study
was to compare the prophylactic efficacy of N-Acetylcysteine and dopamine
administration in patients with pre-existing moderate renal insufficiency
who were undergoing cardiopulmonary bypass.MethodsThis study included 135 patients with pre-existing moderate renal
insufficiency who were scheduled for coronary artery bypass grafting
surgery. Serum creatinine and GFR were recorded preoperatively and on the
first and second postoperative days.ResultsOn the first and second postoperative days, the drugs used showed
statistically significant differences among the creatinine groups
(P<0.001). According to Tukey’s HSD, on the first
and second PO, the creatinine of Group N, D and P were significantly
different (P<0.001). On the first and second PO, the
used drugs showed statistically significant differences among the effects of
eGFR (P<0.001). According to Tukey’s HSD on the first
postoperative day, the average eGFR score of Group N compared to D and P
were significantly difference (P<0.001). On the second
postoperative day, the eGFR of Group N and D showed no difference
(P=0.37), but P showed a difference
(P<0.001).ConclusionWe found that the prophylactic use of intravenous N-Acetylcysteine had a
protective effect on renal function, whereas the application of renal dose
dopamine did not have a protective effect in patients with pre-existing
moderate renal failure.
In elderly women, revascularization procedures can be done with acceptable mortality rates; but these patients are still associated with a higher prevalence of postoperative morbidity when compared with the male counterparts. Therefore, these patients have to be very carefully evaluated preoperatively and their postoperative care should be more comprehensive to reduce the incidence of postoperative complications.
