Management of critically ill nontrauma (CINT) patients in the resuscitation room of the emergency department (ED) is very challenging. Detailed data describing the patient characteristics and management of this population are lacking. This observational study describes the epidemiology, management and outcome in CINT ED patients in the resuscitation room. ⋯ Observation of critically ill patient management in the ED resuscitation room showed reliable results between both study periods. Structured ED management guidelines for CINT patients may provide comparable results at one institution.

Breathing lime is used in closed circuit and semi-closed circuit rebreathers (CCR/SCR) for technical diving. Similar to the use in anesthesia systems, the lime usually contains hydroxycarbamide, which can react to caustic soda under the influence of water. The ingestion of components of the soda lime can lead to burns of the esophageal mucosa with the formation of colliquation necrosis and the danger of esophageal perforation. Early endoscopy is essential in this case to assess the consequences of ingestion.

Sympathomimetic drugs are a therapeutic cornerstone for the management of hypotensive states like intraoperative hypotension (IOH). While cafedrine/theodrenaline (C/T) is widely used in Germany to restore blood pressure in patients with IOH, more research is required to compare its effectiveness with alternatives such as ephedrine (E) that are more commonly available internationally. ⋯ Neither drug was superior in restoring blood pressure levels; however, post-hoc analyses suggested that treatment is more goal-orientated and easier to control with C/T. Heart rate was shown to be more stable with C/T and fewer additional interventions were required to restore blood pressure, which could have contributed to the increased treatment satisfaction reported by anesthetists using C/T.

Segawa syndrome (dopa-responsive dystonia [DRD]) is a rare neurometabolic disorder characterized by progressive dystonia, diurnal variation and tremors. It is caused by an enzymatic defect (a mutation of the GTPCH1 gene located on chromosome 14q) in the synthesis of tetrahydrobiopterin, an important substrate for dopamine synthesis. In the case of early correct diagnosis, clinical symptoms are well-controlled by levodopa therapy. ⋯ Preoperative medication with levodopa should not be interrupted. Pharmacological agents with an antidopaminergic mode of action have to be avoided as well as significant pain and emotional stress situations in the perioperative period. Surgery in an ambulatory setting may not be recommended.

Inhalational anesthetics have been used for induction and maintenance of general anesthesia for more than 150 years. All of the currently used inhalational anesthetics are chlorinated and fluorinated derivatives of ether. Dosing is carried out using the minimal alveolar concentration (MAC) concept. ⋯ The role of inhalational anesthetics in the context of postoperative nausea and vomiting (PONV) has been reassessed in recent years. The superiority of inhalational anesthetics over intravenous hypnotics with respect to intraoperative awareness is undisputed. The organ protective mechanism of preconditioning is an exclusive property of inhalational anesthetics among all the currently available hypnotics.
