Toxic reactions to local anesthetics are rare but potentially lethal. In fact, animal studies and case reports demonstrate that the administration of lipid emulsions after initializing cardiopulmonary resuscitation is a promising treatment option. The aim of this study was to determine how many hospitals in Germany are prepared to treat toxic reactions to local anesthetics with lipid infusion and to identify how often and what type of toxic reactions occur and if treatment was successful. Further, we aimed to elucidate if current guidelines lead to more immediate availability of lipid emulsions in direct proximity to the room where regional anesthesia is performed. ⋯ The majority of surveyed German hospitals are prepared to treat toxic reactions to local anesthetics and published guidelines contributed to this preparedness. The infusion of lipid emulsions is a promising measure to deal with toxic reactions to local anesthetics. Since toxic reactions to local anesthetics are potentially lethal, it seems desirable that lipid emulsions are generally available in routine clinical practice. Currently, the treatment of toxic reactions to local anesthetics is mostly performed in situations (e.g. treatment of prodromal symptoms) that are not recommended by current guidelines. Further research is necessary to better define the future use of lipid emulsions in routine clinical practice.

["Why mothers die" : Learning from the analysis of anaesthesia-related maternal deaths (1985-2013)].
Every day, more than 800 women die from causes related to pregnancy or childbirth. Since 1952 the Confidential Enquiry of Maternal Deaths Reports (CEMD) have collected and analysed data on maternal mortality in the United Kingdom and Northern Ireland. This publication analyses the CEMD from 1985-2013 regarding anaesthesia- and analgesia related maternal deaths during pregnancy or peripartum. ⋯ Vital sign monitoring after obstetric anaesthesia has to be identical to other postoperative monitoring, and Modified Early Warning Scores should be used for this purpose. In regional anaesthesia, current standards for hygiene have to be adhered to and patients have to be visited after spinal/epidural anaesthesia. Interdisciplinary communication and collaboration still have to be improved; careful interdisciplinary planning of childbirth in high-risk obstetric patients is strongly advised.

Wound management is one of the major tasks in emergency departments. The surrounding intact skin but not the wound itself should be disinfected before starting definitive wound treatment. Hair should first be removed by clipping to 1-2 mm above the skin with scissors or clippers as shaving the area with a razor damages the hair follicles and increases the risk of wound infections. ⋯ For strongly bleeding lacerations of the scalp, the epicranial aponeurosis should be incorporated into the hemostasis. Aftercare varies depending on both the characteristics of the wound and those of the patient and includes adequate analgesia as well as minimizing the risk of infection. Sufficient wound aftercare starts with the treating physician informing the patient about the course of events, potential complications and providing relevant instructions.

The role of dexamethasone as an adjunct in peripheral nerve blockades is still unclear. ⋯ After reviewing the actual literature, the authors prefer a systemic application mode (intravenously) over a perineural route of administration of dexamethasone as an adjunct for peripheral nerve blocks. This is due to the better understanding of potential side effects of the drug when applied intravenously. Dexamethasone might be a useful drug adjunct to prolong peripheral single shot nerve blocks.
