Abstract
-
Adequate intraoperative infusion therapy is essential for the perioperative outcome of a patient. Both hypo- and hypervolemia can lead to an increased rate of perioperative complications and to a worse outcome. Perioperative infusion therapy should therefore be needs-based. ⋯ Stage 2: blood losses exceeding this level are to be treated with isooncotic colloids (preferably balanced) in a 1:1 ratio. In this regard taking into consideration the contraindications, e. g., sepsis, burns, critical illness (usually patients in the intensive care unit), impaired renal function or renal replacement therapy, intracranial hemorrhage, or severe coagulopathy, artificial colloids such as hydroxyethyl starch (HES) can be used perioperatively for volume replacement. Stage 3: if an allogeneic blood transfusion is indicated, blood and blood products are applied in a differentiated manner.

Clinical Trial
Comparison of cervical spine motion during intubation with a C‑MAC D‑Blade® and an LMA Fastrach®.
This prospective randomized study compared cervical motion during intubation with a C‑MAC D‑Blade® and with a laryngeal mask airway LMA Fastrach®. ⋯ Intubation with both a C‑MAC D‑Blade and a Fastrach LMA resulted in cervical motion but within safe ranges. Intubation with a C-mac D blade might be preferred because the Fastrach LMA may result in more failed intubation attempts in patients with cervical spine disorders.

[Comparison of sublingual and intravenous administration of lorazepam in psychiatric emergencies in emergency medical services].
Agitation is a frequent reason for emergency physician calls in psychiatric emergencies in the German preclinical emergency medical system. Benzodiazepines have proven to be effective in treating acute agitation. Although lorazepam has beneficial clinical and pharmacological properties it is hardly used by emergency physicians. The sublingual administration of lorazepam has many advantages compared to intravenous administration. ⋯ Sublingual administration of lorazepam is effective for treating acute agitation in emergency medical services.

Although dehydration is a serious condition associated with significant morbidity and mortality in palliative care patients, as in any other patient group, treatment remains controversial. A narrative review of the causes of dehydration during end of life was conducted paying special attention to the nature of terminal dehydration. ⋯ The following inferences can be derived: 1) the available evidence does not support a clear decision in favor or against fluid therapy during the dying phase. 2) There is inadequate precision of the term end of life care (ELC) and insufficient differentiation between modes of dehydration of palliative care patients. 3) Evaluation of dehydration based on its clinical appearance is considered the method of choice compared to invasive procedures. 4) Detailed clinical assessment of symptom reversibility in terminal dehydration by an appropriate fluid challenge is mandatory in the decision-making process. 5) If despite adequate rehydration measures, complete reversibility of the clinical picture of dehydration can no longer be achieved since organ systems are gradually deteriorating, the cessation of clinically assisted hydration (CAH) can be considered. 6) If symptoms of dehydration are reversible after fluid challenge and no other patient wishes to the contrary are known, fluid management should be continued in the context of symptom control. 7) Hyperhydration represents a considerable threat during fluid management that needs to be prevented by noninvasive monitoring procedures. In conclusion, if CAH is applied as a part of ELC the hydration status needs to be individually appraised and all therapeutic measures constantly need to be adapted to the findings of diligent monitoring procedures.
