Randomized Controlled TrialComparison of the i-gelTM with the AuraGainTM laryngeal mask airways in patients with a simulated cervical immobilization: a randomized controlled trial.
The use of second generation supraglottic airway devices is recommended for airway rescue in failed tracheal intubation. This study was performed to compare the clinical performance of the i-gel™ with that of the AuraGain™ in patients with simulated cervical immobilization. ⋯ The i-gel™ and the AuraGain™ showed comparable oropharyngeal leak pressures and success rates in the first attempt in patients with simulated cervical immobilization. However, the i-gel™ was easier to insert and required less time for insertion than the AuraGain™.

Observational StudyNeuromuscular monitoring using TOF-Cuff® versus TOF-Scan®: an observational study under clinical anesthesia conditions.
Anesthesia guidelines advise objective neuromuscular monitoring. Acceleromyography, the standard technique used in clinical practice, is commonly used with the train-of-four (TOF) nerve stimulation pattern. Objective of this study was to compare the performance of two devices, TOF-Scan® and TOF-Cuff®. ⋯ TOF-Cuff® consistently recorded the endpoints earlier than TOF-Scan®. Despite large intra-individual variations found with both devices, these results could be meaningful in a clinical setting.

A new pressure guided management tool for epidural space detection: feasibility assessment in a clinical scenario.
The detection of epidural space is usually performed by the technique of loss of resistance (LOR) without technological support, although there are few commercial options. In this work, we aimed to assess the feasibility of a new, non-invasive, mechatronic system for LOR detection in clinical settings. The system allows monitoring the pressure exerted on the syringe plunger by the clinician during the puncture. The LOR is related to the mentioned pressure. ⋯ The proposed mechatronic system successfully detected the LOR in the large part of cases using the configurations characterized by the best trade-off between system sensitivity and range of measurements. A non-significant increment of the procedure time is related to the use of the system.

Presepsin is the soluble fragment of CD14, a multifunctional glycoprotein expressed on the surface of innate immune cells. In healthy individuals, presepsin is present in very low concentrations with reference values ranging from 60 to 382 pg/mL. ⋯ Elevated plasma presepsin concentration has also been reported in patients undergoing cardiac and non-cardiac surgery and it has further been evaluated as a potential independent predictor of perioperative cardiovascular complications and mortality. Combined cardiac and inflammatory biomarker evaluation may offer additive predictive information, but further investigations in large populations are required to determine presepsin diagnostic and prognostic value, in order to personalize therapy and reduce surgical patients' morbidity and mortality.

Osmotic Demyelination Sindrome: epidemiology, cause and management. Are patients with end stage liver disease a special risk group?
The osmotic demyelination syndrome (ODS) is a serious neurological complication associated with the rapid correction of chronic hyponatremia and is associated with high morbidity and mortality. The incidence of ODS after liver transplantation (LT) is 0.8% to 1.4% and is higher than in the general population. Patients with end stage liver disease (ESLD) are very susceptible to ODS primarily because chronic hyponatremia is the most common electrolyte disorder in these patients. ⋯ Chronic symptomatic hyponatremia should be carefully treated if LT is imminent. An intraoperative management strategy to minimize increases in sNa is vital and includes limiting fresh frozen plasma and cryoprecipitate administration by using concentrated clotting factors, administering hypotonic intravenous fluids and sodium-free buffering solutions, as well as using low-sodium continuous renal replacement therapy. sNa levels and urine output should be monitored frequently intraoperatively as well as postoperatively. Neurological symptoms are common after LT, and a high index of suspicion must be maintained to diagnose ODS.
