The admission blood glucose level after cardiac arrest is predictive of outcome. However the blood glucose levels in the post-resuscitation period, that are optimal remains a matter of debate. We wanted to assess an association between blood glucose levels at 12h after restoration of spontaneous circulation and neurological recovery over 6 months.

A total of 234 patients from a multi-centre trial examining the effect of mild hypothermia on neurological outcome were included. According to the serum glucose level at 12h after restoration of spontaneous circulation, quartiles (Q) were generated: Median (range) glucose concentrations were for QI 100 (67–115mg/dl), QII 130 (116–143mg/dl), QIII 162 (144–193mg/dl) and QIV 265 (194–464mg/dl).

In univariate analysis there was a strong non-linear association between blood glucose and good neurological outcome (odds ratio compared to QIV): QI 8.05 (3.03–21.4), QII 13.41 (4.9–36.67), QIII 1.88 (0.67–5.26). After adjustment for sex, age, “no-flow” and “low-flow” time, adrenaline (epinephrine) dose, history of coronary artery disease and myocardial infarction, and therapeutic hypothermia, this association still remained strong: QI 4.55 (1.28–16.12), QII 13.02 (3.29–49.9), QIII 1.37 (0.38–5.64).

There is a strong non-linear association of survival with good neurological outcome and blood glucose levels 12h after cardiac arrest even after adjusting for potential confounders. Not only strict normoglycaemia, but also blood glucose levels from 116 to 143mg/dl were correlated with survival and good neurological outcome, which might have an important therapeutic implication.
