Objective: To explore the relationship between the blood glucose and its prognosis after CPB operation.Methods: 408 consecutive adult patients underwent CPB surgery from June 2008 to December 2008 were enrolled to the study.The blood glucose was measured over the first 48 hours postoperatively.Any other clinical datum were also collected.Results: The highest blood glucose level was used to classify patients for 2 groups.The normal group(<11.1 mmol/L) had 308 patients(75.49%) and the abnormal group(≥11.1 mmol/L) had 100 patients(24.51%).The in-hospital mortality of these 2 groups were 0.32%(1/308) and 12%(12/100)

P<0.01

RR=37.5

95%CI(1.59～5.65).The incidence of complications were 6.17%(19/308) and 63%(63/100)

P<0.01

RR=10.21

95%CI(1.86～2.78).There was statistically significant difference between the 2 groups.Although the intraoperative blood glucose and bypass time were associated with prognosis

postoperative blood glucose can not only predict complications more accurately(regression coefficient=0.684

P<0.01)

but also be an independent risk factor for prognosis(regression coefficient=-0.390

P<0.01)

which was verified by multivariate logistic regression analysis.Conclusion: The blood glucose in the early postoperation was associated with the prognosis.The higher the blood glucose was

the worse the consequence.
