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.

Patient-controlled sedation with propofol for endoscopic procedures - a cost-analysis.
Patient-controlled sedation (PCS) with propofol accompanied by a bedside nurse anaesthetist is an alternative sedation method for endoscopic procedures compared with midazolam administered by a nurse or endoscopist. Increasing costs in health care demands an economic perspective when introducing alternative methods. We applied a hospital perspective on a cost analysis comparing different methods of sedation and the resource use that were expected to affect cost differences related to the sedation. ⋯ Propofol PCS with a bedside nurse anaesthetist reduces the direct sedation costs for ERCP and bronchoscopy procedures compared with midazolam sedation.

Observational StudyDementia and CSF-Biomarkers for Alzheimer's Disease Predict Mortality after Acute Hip Fracture.
Mortality is high after an acute hip fracture (AHF) surgery. Are cognitive impairment and/or altered levels of Alzheimer's Disease (AD)-biomarkers in cerebrospinal fluid (CSF) predictors of mortality in AHF-patients, as retrospective studies indicate? ⋯ Cognitive impairment and altered CSF biomarker concentrations indicative of AD pathology can predict increased mortality in patients with an AHF, and so probably even before clinical dementia diagnosis by early biomarker analysis; a notion that may have substantial clinical implications by improving perioperative treatment and postoperative rehabilitation.

Observational StudyBedside Interpretation Of Simplified Continuous EEG After Cardiac Arrest.
Continuous EEG-monitoring (cEEG) in the ICU is recommended to assess prognosis and detect seizures after cardiac arrest but implementation is often limited by the lack of EEG-technicians and experts. The aim of the study was to assess ICU physicians ability to perform preliminary interpretations of a simplified cEEG in the post cardiac arrest setting. ⋯ After cardiac arrest, preliminary bedside interpretations of simplified cEEGs by trained ICU physicians may allow earlier detection of clinically relevant cEEG changes, prompting changes in patient management as well as additional evaluation by an EEG-expert. This strategy requires awareness of limitations of both the simplified electrode montage and the cEEG interpretations performed by ICU physicians. cEEG evaluation by an expert should not be delayed.

Long-term Survival after Intensive Care: a retrospective cohort study.
Background Limited data exist on long-term survival of patients requiring admission to intensive care units (ICUs). The aim of this study was to investigate long-term survival of ICU patients in Iceland and assess changes over a 15-year period. Methods Data were collected on age, gender, admission cause, length of stay, comorbidities, mechanical ventilation and survival of patients 18 years and older admitted to the ICUs in Landspitali during 2002-2016. ⋯ There was a high variability in the estimated time point where the ICU admission had no residual effect on survival. Conclusions Long-term survival of ICU patients is substantially decreased compared to the general population, but varies based on admission causes. Improved long-term survival of patients admitted with infections could be explained by earlier detection and improved treatment of septic shock.
