The current guidelines of the European Resuscitation Council recommend targeted temperature management to improve functional neurological outcome in comatose survivors after cardiac arrest. With the pathophysiological background of hypothermia-induced neuroprotection for prevention of hypoxic-ischemic encephalopathy, targeted temperature management is a key measure and represents a central aspect in postresuscitation care. In the 2021 guidelines the application of targeted temperature management in postresuscitation care has been recommended for all rhythms and irrespective of the location of cardiac arrest. ⋯ Furthermore, recent data on preclinical management, different patient populations, the duration of targeted temperature management, cooling methods and rebound hyperthermia are discussed. The impact of targeted temperature management on neurological outcome after cardiac arrest has been a matter of controversy. Despite contradictory results and heterogeneity of study designs, the current evidence supports the relevance and the necessity of strict temperature control in postresuscitation care for neuroprotection and improvement in functional neurological outcomes.

In 1981 the Canadian Peter Stewart presented a new concept for the interpretation of the acid-base balance. Rehm et al. published the first German language article on this topic. ⋯ This gap is intended to be filled by this work. It introduces a simple, practical algorithm and provides an approach to understanding the acid-base balance and the Stewart concept, which assumes that the plasma ions determine the pH value and the base excess (BE) in the plasma.

We report on a 28-year-old female patient who had no history of diseases and who was brought to our intensive care unit in a comatose state by the ambulance service. The clinical picture corresponded to sepsis with a massively increased blood sugar concentration (> 2000 mg/dl) as well as a pronounced skin mycosis in the groin region of the very obese patient (body mass index [BMI]: 33.7 kg/m2) in the physical examination. The treatment of sepsis was initially supplemented by a calculated antifungal treatment. ⋯ The patient died on day 24 after admission to the intensive care unit. The case study shows that antifungal treatment should definitely be considered in the context of sepsis treatment if there is a clinically justified suspicion. The role of the severely altered metabolic situation with massive hyperglycemia and ketoacidosis cannot be finally assessed.

In the prehospital acute treatment phase of severely injured patients, the stabilization of the vital parameters is paramount. The rapid and precise assessment of the injuries by the emergency physician is crucial for the initial treatment and the selection of the receiving hospital. ⋯ In the prehospital care of severely injured patients, the overall injury severity is often correctly recorded by the emergency physician and correlates well with the derived treatment, the selection of the receiving hospital as well as the clinical course and the patient outcome; however, the assessment of injuries of individual body regions seems to be challenging in the prehospital setting.

In German emergency rescue services, inhalation treatment is routinely carried out by qualified health personnel. Standard operating procedures (SOP) for nebulization are neither uniform throughout Germany nor available in all federal states. Standardized recommendations with respect to which nebulizer type should be used are missing. The aerosol output as well as the drug deposition rates of jet and mesh nebulizers, however, differ considerably. Mesh devices can achieve a threefold higher lung deposition. Their use in emergency departments has also been shown to be associated with a better patient outcome when compared to jet nebulizers. ⋯ The exclusive use of mesh nebulizers could standardize the treatment of emergency patients in the south German rescue services. The use of mesh devices might possibly improve patient outcomes, even if clinical studies are still lacking. Nebulizer treatment differs between the federal states. A comprehensive implementation of SOP for nebulization treatment might support this process and could increase the application frequency and the perceived safety of nebulization during emergencies. A better training of paramedic personnel could improve the knowledge of aerosols as a treatment option for emergency patients and help to classify the advantages and disadvantages of the different aerosol generators available.
