Multicenter Study
Thromboelastometry (ROTEM) in children: age-related reference ranges and correlations with standard coagulation tests.
The small sample volume needed and the prompt availability of results make viscoelastic methods like rotational thromboelastometry (ROTEM) attractive for monitoring coagulation in small children. However, data on reference ranges for ROTEM parameters in children are scarce. ⋯ Reference ranges for ROTEM assays were determined for all paediatric age groups. These values will be helpful when monitoring paediatric patients and in studies of perioperative coagulation in children.

Multicenter Study
Differential impacts of modes of anaesthesia on the risk of stroke among preeclamptic women who undergo Caesarean delivery: a population-based study.
This study compared the stroke-free survival rates and hazard ratios (HRs) for stroke between preeclamptic women who received general anaesthesia and those who received neuraxial anaesthesia for Caesarean section (CS). ⋯ In this study, general anaesthesia for CS delivery was associated with increased risk of stroke when compared with neuraxial anaesthesia in preeclamptic women.

Revised cardiac risk index and postoperative morbidity after elective orthopaedic surgery: a prospective cohort study.
The revised cardiac risk index (RCRI) is associated strongly with increased cardiac ischaemic risk and perioperative death. Associations with non-cardiac morbidity in non-cardiac surgery have not been explored. In the elective orthopaedic surgical population, morbidity is common but preoperative predictors are unclear. We hypothesized that RCRI would identify individuals at increased risk of non-cardiac morbidity in this surgically homogenous population. ⋯ mRCRI score ≥ 3 is associated with increased postoperative non-cardiac morbidity and prolonged hospital stay after elective orthopaedic procedures. mRCRI can contribute to objective risk stratification of postoperative morbidity.
