Extraglottic airway devices (EGA) are not only used in routine anaesthesia practice, they also have a distinct value for in-hospital and out-of-hospital difficult airway management. In the environment of the intensive care unit (ICU) EGA are not used on a regular basis. ⋯ This review presents the potential indications for EGA on the ICU for the management of difficult airway situations as well as during percutaneous tracheotomy. Furthermore, the possible advantages of EGA during postoperative recovery from anaesthesia as well as termination of controlled ventilation for intensive care patients are discussed.

Intoxication due to local anaesthetic drugs poses a rare but potentially life-threatening complication. In particular long-acting local anaesthetics can cause refractory cardiac arrest due to their lipophilic properties. This is often preceded by neurological symptoms such as confusion, vertigo and tonic-clonic seizures. ⋯ In case of cardiac arrest standard protocols for cardiopulmonary resuscitation have to be implemented immediately. The use of lipid emulsion can then be initiated as a supplement to standard resuscitation. It is recommended that lipid emulsions are instantly accessible in all facilities where local anaesthetics are administered.

Fibromyalgia ossificans progressiva (FOP) is a severely disabling disorder of connective tissue characterized by congenital malformation of the toes, fingers and vertebrae associated with progressive ossification of striated muscles. Anesthetic management of these patients involves preferably general anesthesia as local or regional anesthesia should be avoided due to possible heterotopic ossification. Airway management is determined by the age of the patient and the progression of the disease. ⋯ As demonstrated and discussed in this case report of a 2-year-old boy, fiberoptic intubation after induction of general anesthesia should be preferred in pediatric patients. Puncture of a vein should be non-traumatic, i.m. injections strictly avoided and careful positioning and padding are needed. Every effort should be made to avoid situations stimulating new heterotopic ossification due to its substantial effect on the quality of life of FOP patients.

In order to reduce the incidence of postoperative nausea and vomiting (PONV) a standard operating procedure (SOP) was developed in our department. This consists basically in the administration of one antiemetic intervention for moderate risk (2 risk factors), two interventions for high risk (3-4 risk factors) and no prophylaxis in patients who have no or only one risk factor. The aim of this study was to find out whether PONV prophylaxis according to our SOP was followed and led to a lower incidence of PONV. ⋯ Patients with medium and high risk have a lower incidence of PONV than expected per risk calculation by complying with the SOP. However, the recommended risk-adapted approach was inadequately implemented. Considering this there is room for improvement. Moreover taking into account these implementation issues a general PONV prophylaxis may be beneficial.

Randomized Controlled Trial Comparative Study
[Topical anesthesia before vascular access in children. Comparison of a warmth-producing lidocaine-tetracaine patch with a lidocaine-prilocaine patch].
Venepuncture is one of the most stressful situations for children during induction of general anesthesia. Therefore, many clinicians use a local anesthesia patch (EMLA) containing a mixture of lidocaine and prilocaine in order to reduce the stress for pediatric patients. This study compared the effect of a new heated topical anesthesia delivery system containing lidocaine and tetracaine (Rapydan) with the lidocaine/prilocaine patch EMLA. ⋯ After a contact time of 35 min the Rapydan patch led to superior analgesia during venous puncture than the EMLA patch. With regard to visibility of the veins and success rate of the punctures, differences between the two patches were not observed.
