Dural puncture, paraesthesia and vascular puncture are the most common complications of epidural catheter insertion. Their association with variation in midline needle insertion depth is unknown. ⋯ Variation in midline insertion depth is an independent risk factor for epidural complications; however, variability precludes use of depth as a reliable guide to insertion in individual patients.

Case Reports
Misleading symptoms and successful noninvasive rewarming of a patient with severe hypothermia (23.1 °C).
Accidental severe hypothermia is a medical emergency in which symptoms may include coma, apnea, pulmonary edema, ventricular dysrhythmia or asystole. Despite optimal treatment, mortality remains high. This article reports a case of severe hypothermia in a geriatric hypothyroid patient, where despite a body core temperature of 23.1 °C the patient presented conscious and with stable vital signs, pronounced motor response, and a Glasgow Coma Scale score of 9. ⋯ Hypothyroidism may have contributed to this uncommon clinical presentation. Body temperature needs to be taken into account when interpreting blood gas analyses. Even at the stage of severe hypothermia, noninvasive forced-air warming enabled rewarming without complications.

In January 2018 the recent revision of the S2k guidelines on calculated parenteral initial treatment of bacterial diseases in adults-update 2018 (Editor: Paul Ehrlich Society for Chemotherapy, PEG) was realized. It is a helpful tool for the complex infectious disease setting in an intensive care unit. The present summary of the guidelines focuses on the topics of anti-infective agents, including new substances, pharmacokinetics and pharmacodynamics as well as on microbiology, resistance development and recommendations for calculated drug therapy in septic patients. As in past revisions the recent resistance situation and results of new clinical studies are considered and anti-infective agents are summarized in a table.

Whole-body computed tomography (CT) is increasingly being used as the diagnostic modality of choice in patients admitted to the resuscitation room. Beyond findings related to the suspected diagnosis it often additionally reveals incidental findings. The aim of this investigation was the evaluation of these findings in patients admitted via the emergency room after suffering potential major trauma or life-threatening medical conditions. Furthermore, the number of iatrogenic injuries as well as misplaced catheters and endotracheal tubes was investigated. ⋯ In addition to the main diagnosis, clinically relevant incidental findings were reported in nearly 25% of whole-body CT scans of patients admitted to the resuscitation room. Approximately 6% of patients had incidental findings rated as clinically relevant. In the internal neurological group of patients the rate of incidental findings was doubled compared to the trauma group; however, the latter were significantly younger. Whole-body CT was also useful for diagnosing iatrogenic injuries and misplaced catheters in approximately 4% of the study patients.
