Observational StudyEffect of external dead space removal on CO2 homeostasis in mechanically ventilated adult Covid-19 patients.
Patients with Covid-19 respiratory failure present with hypoxemia, often in combination with hypercapnia. In this prospective, observational study we examined the effect of removing external dead space (DS) on CO2 -homeostasis in mechanically ventilated Covid-19 patients. In addition, volumetric capnography was validated for its ability to estimate external DS volume using in vitro measured DS volumes as reference. ⋯ Removal of external DS increased alveolar minute ventilation and CO2 elimination in Covid-19 patients with respiratory failure in the current study. This was associated with a decrease in PaCO2 . This may indicate a decreased CO2 production due to decreased work of breathing and more effective gas-exchange in response to DS removal. In addition, volumetric capnography appears to be a clinically feasible method for continuous measurement of external DS in the current study and may be of value in optimizing ventilator treatment.

ReviewThe Nordic perioperative and intensive care registries-Collaboration and research possibilities.
The Nordic perioperative and intensive care registries have been built up during the last 25 years to improve quality in intensive and perioperative care. We aimed to describe the Nordic perioperative and intensive care registries and to highlight possibilities and challenges in future research collaboration between these registries. ⋯ Collaboration between the Nordic perioperative and intensive care registries is both possible and likely to produce research of high quality. Research collaboration between registries may have several add-on effects and stimulate international standardization regarding definitions, scoring systems, and benchmarks, thereby improving overall quality of care.

Perioperative management of patients declining transfusions of blood components-National survey of anaesthesiologists, abdominal surgeons and obstetricians in Denmark.
Perioperative management of patients declining transfusions of blood products can be challenging both ethically and clinically. Jehovah's Witnesses (JW) decline treatment with blood products and have published a list of interventions they might accept as substitutes. No detailed documentation of available substitute interventions at Danish hospitals exists. ⋯ Depending on the type of anticoagulant, between 31 (32%) and 59 (60%) of respondents reported locally available guidelines for reverting anticoagulant treatments. We found a considerable variation and limited availability of interventions to minimise blood loss in patients declining transfusion of blood components. This scarcity of local guidelines together with the considerable variation of available treatment documented in our survey could possibly be enhanced by a lack of national guidelines.

Randomized Controlled TrialMild induced hypothermia and coagulation and platelet function in patients with septic shock: Secondary outcome of a randomized trial.
Coagulation abnormalities and microthrombi contribute to septic shock, but the impact of body temperature regulation on coagulation in patients with sepsis is unknown. We tested the hypothesis that mild induced hypothermia reduces coagulation and platelet aggregation in patients with septic shock. Secondary analysis of randomized controlled trial. ⋯ Platelet aggregation was slightly impaired. The effect of mild induced hypothermia on viscoelastography and platelet aggregation was however not in a range that would have clinical implications. We did observe a substantial reduction in fibrinolysis.

Healthcare professionals' perception of their working environment and how to handle mental strain.
Healthcare professionals (HCP) are an important resource, but the shortage of staff and an increased volume of patients with comorbidities might put a pressure on them. We speculated if mental strain was a challenge for HCP working in a department of Anaesthesiology. The purpose of the study was to explore HCP's perception of their psychosocial work environment and how they handle the mental strain in a department of Anaesthesiology in a university hospital. ⋯ Teamwork is described as strong in some sections. All HCP had experienced mental strain. Differences were found in how they perceived the experience of mental strain, their reactions and needs of support as well as their coping strategies.
