Myocardial injury and mortality in patients with excessive oxygen administration before cardiac arrest.
Hyperoxia after cardiac arrest may be associated with higher mortality, and trials have found that excess oxygen administration in patients with myocardial infarction is associated with increased infarct size. The effect of hyperoxia before cardiac arrest is sparsely investigated. Our aim was to assess the association between excessive oxygen administration before cardiac arrest and the extent of subsequent myocardial injury. ⋯ Of 163 patients with cardiac arrest, 28 had excessive oxygen administration (17%), 105 had normal oxygen administration (64%) and 30 had insufficient oxygen administration (18%) before cardiac arrest. Peak troponin was median 224 ng/L in the excessive oxygen administration group vs 365 ng/L in the normal oxygen administration group (P = .54); 20 of 28 (71%) in the excessive oxygen administration group died within 30 days compared to 54 of 105 (51%) in the normal oxygen administration group. (OR 1.87, 95% CI 0.56-6.19) CONCLUSIONS: Excessive oxygen administration within 48 hours before in-hospital cardiac arrest was not statistically associated with significantly higher peak troponin or mortality.

ReviewClinical practice guideline on prevention of rhabdomyolysis induced acute kidney injury: Endorsement by the Scandinavian Society of Anaesthesiology and Intensive Care Medicine.
The Scandinavian Society of Anaesthesiology and Intensive Care Medicine Clinical Practice Committee endorses the recent DASAIM/DSIT guideline for prevention of rhabdomyolysis-induced acute kidney injury. However, we emphasize the low quality of evidence with only weak recommendations for all interventions, highlighting that further research is very likely to have an important impact on the confidence in the estimate of effect and is likely to change the estimates.

Randomized Controlled TrialSpinal and epidural sufentanil and fentanyl in early labour.
The analgesic effect on labour pain of either spinal or epidural sufentanil or fentanyl was tested in a total of 80 primiparous parturients at an early phase of the delivery. The aim of the study was to compare the level of analgesia achieved within 20 minutes. ⋯ In terms of a reduction of VAS score at 20 minutes, epidural sufentanil or fentanyl provide 63% and 60% of the analgesic effect of the corresponding spinal analgesia. Epidural sufentanil or fentanyl could be used in situations in which spinal/CSE administration is not possible or desired.

Observational StudyPoint-of-care analyses of blood samples from intraosseous access in pre-hospital critical care.
Intraosseous (IO) access is used for fluid and medication administration in emergency situations when difficulties with vascular access are encountered. IO access would be readily available to take samples for point-of-care (POC) analysis, but there is scarce evidence about the reliability of POC analysis of IO samples among emergency patients. The aim of this study was to evaluate the feasibility and reliability of POC analysis of IO samples in critically ill pre-hospital patients. ⋯ When vascular access is challenging, IO access can be used for emergency POC analyses to help guide clinical decision-making. However, the limitations of IO POC analyses must be carefully considered.

Impact of norepinephrine on right ventricular afterload and function in septic shock-a strain echocardiography study.
In this observational study, the effects of norepinephrine-induced changes in mean arterial pressure (MAP) on right ventricular (RV) systolic function, afterload and pulmonary haemodynamics were studied in septic shock patients. We hypothesised that RV systolic function improves at higher doses of norepinephrine/MAP levels. ⋯ Higher doses of norepinephrine to a target MAP of 90 mm Hg improved RV systolic function while RV afterload was not affected.
