Background Critically ill infants and children often develop hyperglycaemia, which is associated with adverse outcome; however, whether lowering blood glucose concentrations to age-adjusted normal fasting values improves outcome is unknown. We investigated the effect of targeting age-adjusted normoglycaemia with insulin infusion in critically ill infants and children on outcome. Funding Research Foundation (Belgium); Research Fund of the University of Leuven (Belgium) and the EU Information Society Technologies Integrated project “CLINICIP”; and Institute for Science and Technology (Belgium).

Methods In a prospective, randomised controlled study, we enrolled 700 critically ill patients, 317 infants (aged <1 year) and 383 children (aged ≥1 year), who were admitted to the paediatric intensive care unit (PICU) of the University Hospital of Leuven, Belgium. Patients were randomly assigned by blinded envelopes to target blood glucose concentrations of 2 ・ 8–4 ・ 4 mmol/L in infants and 3 ・ 9– 5 ・ 6 mmol/L in children with insulin infusion throughout PICU stay (intensive group [n=349]), or to insulin infusion only to prevent blood glucose from exceeding 11 ・ 9 mmol/L (conventional group [n=351]). Patients and laboratory staff were blinded to treatment allocation. Primary endpoints were duration of PICU stay and inflammation. Analysis was by intention to treat. This study is registered with ClinicalTrials.gov, number NCT

DNR=do not resuscitate. *The 19 medical disorders that were considered unsuitable by the treating physician consisted of two patients dependent on home ventilation, six metabolic disorders, two patients for whom it was the personal opinion of the treating physician that it would be inappropriate to participate in a study in view of poor prognosis (although the patients formally did not have a DNR code), and nine patients who had already been treated with intensive insulin therapy elsewhere before assessment for participation.

Insulin infusions were prepared as 10 IU Actrapid HM (Novo Nordisk, Bagsvard, Denmark) in 50 mL NaCl 0 ・ 9% for patients weighing less than 15 kg, as 20 IU Actrapid HM in 50 mL NaCl 0 ・ 9% for those weighing 15– 30 kg, and as 50 IU Actrapid HM in 50 mL NaCl 0 ・ 9% for those weighing more than 30 kg. We used a syringe-driven infusion pump (B/Braun- Perfusor-Space, B Braun, Melsungen, Germany). We set the starting insulin dose at 0.1 IU/kg/h for a first measurement above upper normal limit and at 0.2 IU/kg/h for a first measurement above twice the upper normal limit. The insulin dose was adjusted by 0 ・ 02 IU/h to 1 IU/h increments, on the basis of measurement of blood glucose concentration in undiluted arterial blood at 1–4 h intervals with the ABL700 analyser (Radiometer Medical A/S, Copenhagen, Denmark). The ABL700 analyser reported results as corrected to plasma concentrations. For infants, insulin infusions were stopped when blood glucose fell to less than 2.8 mmol/L, and 1 mL/kg of a 50% dextrose solution was given when blood glucose fell to less than 1.7 mmol/L. For children, we stopped insulin infusions when blood glucose fell to less than 3.9 mmol/L, and 1 mL/kg of a 50% dextrose solution was given when blood glucose fell to less than 2.2 mmol/L (figure 1).

Error bars indicate SE. p value was obtained by repeated measures ANOVA for overall significance of the difference in time course of CRP (time*treatment interaction). The p value for the change in CRP on day 5, calculated by Mann-Whitney U test, was 0 ・ 007.

Table 3: Mortality in the two treatment groups

Findings Mean blood glucose concentrations were lower in the intensive group than in the conventional group (infants: 4 ・ 8 [SD 1 ・ 2] mmol/L vs 6 ・ 4 [1 ・ 2] mmol/L, p median) stay in PICU was 132 (38%) in the intensive group versus 165 (47%) in the conventional group (p=0 ・ 013). Nine (3%) patients died in the intensively treated group versus 20 (6%) in the conventional group (p=0 ・ 038).

Interpretation Targeting of blood glucose concentrations to age- adjusted normal fasting concentrations improved short-term outcome of patients in PICU. The effect on long-term survival, morbidity, and neurocognitive development needs to be investigated.

In this study, adults who were expected to require treatment in the intensive care unit on 3 or more consecutive days were randomly assigned to undergo intensive blood glucose control (target range, 81 to 108 mg per deciliter [4.5 to 6.0 mmol per liter]) or conventional blood glucose control (180 mg per deciliter [10.0 mmol per liter])

Study Overview In this study, adults who were expected to require treatment in the intensive care unit on 3 or more consecutive days were randomly assigned to undergo intensive blood glucose control (target range, 81 to 108 mg per deciliter [4.5 to 6.0 mmol per liter]) or conventional blood glucose control (180 mg per deciliter [10.0 mmol per liter]) The primary end point was death from any cause within 90 days after randomization Intensive glucose control increased mortality among the patients The NICE-SUGAR Study Investigators.

Conclusion In this large, international, randomized trial, we found that intensive glucose control increased mortality among adults in the ICU: a blood glucose target of 180 mg or less per deciliter resulted in lower mortality than did a target of 81 to 108 mg per deciliter The NICE-SUGAR Study Investigators.

Message It would be a disservice to our critically ill patients to infer from the NICE- SUGAR data that neglectful glycemic control involving haphazard therapeutic approaches (e.g., use of insulin “sliding scales”) — all too common a decade ago — is again acceptable practice in our ICUs.
