Purpose We aimed to evaluate post-resuscitation care, implementation of therapeutic hypothermia (TH) and outcomes of intensive care unit (ICU)-treated out-of-hospital cardiac arrest (OHCA) patients in Finland. Methods We included all adult OHCA patients admitted to 21 ICUs in Finland from March 1, 2010 to February 28, 2011 in this prospective observational study. Patients were followed (mortality and neurological outcome evaluated by Cerebral Performance Categories, CPC) within 1 year after cardiac arrest. Results This study included 548 patients treated after OHCA. Of those, 311 patients (56.8 %) had a shockable initial rhythm (incidence of 7.4/100,000/year) and 237 patients (43.2 %) had a non-shockable rhythm (incidence of 5.6/100,000/year). At ICU admission, 504 (92 %) patients were unconscious. TH was given to 241/281 (85.8 %) unconscious patients resuscitated from shockable rhythms, with unfavourable 1-year neurological outcome (CPC 3-4-5) in 42.0 % with TH versus 77.5 % without TH (p < 0.001). TH was given to 70/223 (31.4 %) unconscious patients resuscitated from non-shockable rhythms, with 1-year CPC of 3-4-5 in 80.6 % (54/70) with TH versus 84.0 % (126/153) without TH (p = 0.56). This lack of difference remained after adjustment for propensity to receive TH in patients with non-shockable rhythms. Conclusions One-year unfavourable neurological outcome of patients with shockable rhythms after TH was lower than in previous randomized controlled trials. However, our results do not support use of TH in patients with non-shockable rhythms., Author(s): Jukka Vaahersalo [sup.1] [sup.11], Pamela Hiltunen [sup.2], Marjaana Tiainen [sup.3], Tuomas Oksanen [sup.1], Kirsi-Maija Kaukonen [sup.1], Jouni Kurola [sup.2], Esko Ruokonen [sup.2], Jyrki Tenhunen [sup.4] [sup.5], Tero Ala-Kokko [sup.6], [...]

Objective: Elevated blood glucose is associated with poor outcome in patients resuscitated from out-of-hospital cardiac arrest (OHCA). Our aim was to determine whether strict glucose control with intensive insulin treatment improves outcome of OHCA patients. Design: A randomized, controlled trial. Setting: Two university hospital intensive care units. Patients: Ninety patients resuscitated from OHCA with ventricular fibrillation detected as the initial rhythm were treated with therapeutic hypothermia. Interventions: Patients were randomized into two treatment groups: a strict glucose control group (SGC group), with a blood glucose target of 4-6 mmol/l, or a moderate glucose control group (MGC group), with a blood glucose target of 6-8 mmol/l. Both groups were treated with insulin infusion for 48 h, because a control group with no treatment was considered unethical. Measurements and results: Baseline data were similar in both groups. In the SGC group 71% of the glucose measurements were within the target range compared with 41% in the MGC group. Median glucose was 5.0 mmol/l in the SGC group and 6.4 mmol/l in the MGC group. The occurrence of moderate hypoglycemic episodes was 18% in the SGC group and 2% in the MGC group (p = 0.008). No episodes of severe hypoglycemia occurred. Mortality by day 30 was 33% in the SGC group and 35% in the MGC group (p = 0.846); the difference was 2% (95% CI -18% to +22%). Conclusions: We found no additional survival benefit from strict glucose control compared with moderate glucose control with a target between 6 and 8 mmol/l in OHCA patients.
