Observational StudyClinical Examination Findings As Predictors Of Acute Kidney Injury In Critically Ill Patients.
Acute Kidney Injury (AKI) in critically ill patients is associated with a markedly increased morbidity and mortality. The aim of this study was to establish the predictive value of clinical examination for AKI in critically ill patients. ⋯ Clinical examination findings were able to predict AKI with moderate accuracy in a large cohort of critically ill patients. Findings of clinical examination on ICU admission may trigger further efforts to help predict developing AKI.

Observational StudyRisk factors for shivering during caesarean section under spinal anaesthesia. A prospective observational study.
Shivering during caesarean section (CS) under spinal anaesthesia is a common phenomenon. It could not only alter patient's physiology by increasing oxygen consumption but also affect the parturient's experience of childbirth. Shivering is thought to be associated with intraoperative hypothermia, but the risk factors and exact mechanism remain unclear. ⋯ We failed to prove a strong correlation between the measured variables and shivering. Our findings, however, support the hypothesis, that to a limited extent, anxiety promotes shivering during CS.

Observational StudyNear-Infrared Spectroscopy Monitoring in a Prehospital Trauma Patient Cohort: an analysis of successful signal collection.
Noninvasive monitoring of cerebral physiology could potentially guide pre-hospital management of patients with traumatic injuries. Near-infrared spectroscopy (NIRS) is one such modality but the consistency of monitoring performance remains unclear. This study assessed the proportion of successful signal collection during pre-hospital care. ⋯ In this pre-hospital observational feasibility study with dedicated personnel an acceptable proportion of measurement time was achieved in over 90% of monitored subjects. Addition of NIRS monitoring did not alter pre-hospital scene or transport times in this research setting.

Multicenter Study Observational StudyDepth to the airway lumen at the level of the cricothyroid membrane measured by ultrasound.
Knowing the likely depth to the airway before emergency cricothyroidotomy may improve success in cases where it cannot be measured. Our aim was to measure the depth to the airway at the cricothyroid membrane by ultrasound in a large group of adult patients. ⋯ If ultrasound measurement is not possible before emergency cricothyroidotomy, the clinician could use our results to predict the depth to the airway by using the patient's weight. If the upper 95% CI were used as the depth of incision, it would enter the airway in 39 out of 40 patients of that weight, without damage to posterior structures in those with a shallower airway.
