Hypernatremia-A Manifestation of COVID-19: A Case Series.

We report for the first time therapy-resistant hypernatremia (plasma sodium concentration ≥150 mmol per liter) developing in 6 of 12 critically ill coronavirus disease 2019 (COVID-19) patients age 57-84 years requiring mechanical ventilation. There was no correlation between plasma sodium concentrations and sodium input. Plasma concentrations of chloride were elevated, those of potassium decreased.

[Intrahepatic Hematoma and Pulmonary Embolism in a Young Woman with Oral Contraceptives Complicated by Type II Heparin Induced Thrombocytopenia Requiring ECMO-Therapy: a Case Report].

A 46-year-old woman on oral contraceptives developed an intrahepatic hematoma due to a benign hepatic tumor. As an incidental finding, a computed tomography showed a pulmonary embolism. Unfractionated heparin was given in a prophylactic dosing in an attempt to balance the risk of further intrahepatic bleeding with that of thrombosis.

Perceived barriers to computerised quality documentation during anaesthesia: a survey of anaesthesia staff.

Background: Underreporting of intraoperative events in anaesthesia is well-known and compromises quality documentation. The reasons for such omissions remain unclear. We conducted a questionnaire-based survey of anaesthesia staff to explore perceived barriers to reliable documentation during anaesthesia.

Comparison of Bullard and Airtraq laryngoscopes with conventional laryngoscopy in a manikin study of simulated difficult intubation.

Background: When airway management is difficult, various measures can be taken to facilitate tracheal intubation. The Bullard and Airtraq laryngoscopes were developed for this purpose. We hypothesised that the Bullard and Airtraq laryngoscopes would perform better than a conventional laryngoscope in the management of a simulated difficult airway.

A minor wound with a fatal course.

The authors report on a fatal case of severe tetanus in a 74-year old woman. Despite comprehensive intensive care management they could not achieve a satisfying control of the autonomic dysfunction caused by tetanus. By now there is no established therapy for the treatment of the autonomic dysfunction.

Accuracy of automatic tube compensation in new-generation mechanical ventilators.

Objective: To compare performance of flow-adapted compensation of endotracheal tube resistance (automatic tube compensation, ATC) between the original ATC system and ATC systems incorporated in commercially available ventilators.

Design: Bench study.

Setting: University research laboratory.

Different strategies to keep the lung open: a study in isolated perfused rabbit lungs.

Objective: Atelectatic alveoli can be recruited or kept open either by sustained inflation maneuvers or by positive end-expiratory pressure (PEEP). Little is known about potential interactions between both approaches. Especially, it is not known whether the recruiting effect of sustained inflation maneuvers is maintained in combination with a low PEEP, as suggested recently.

Intratidal compliance-volume curve as an alternative basis to adjust positive end-expiratory pressure: a study in isolated perfused rabbit lungs.

Objective: Repeated collapse and reopening of alveoli have been shown to aggravate lung injury, which could be prevented by positive end-expiratory pressure (PEEP). Yet, how to adjust optimum PEEP is a matter of debate. We suggest a new strategy to adjust PEEP, which is based on the analysis of the intratidal compliance-volume curve.
