The infraclavicular puncture of the subclavian vein is a standard procedure for anesthetists. Meanwhile the literature and recommendations are clear and the use of real-time ultrasound guidance is the standard procedure; however, anesthetists will always get into special circumstances were they have to use the landmark technique, so this competence must be preserved. Feared complications of infraclavicular subclavian vein puncture are pneumothorax and arterial puncture. Up to now there is no clear learning curve for the infraclavicular subclavian vein puncture in the landmark technique performed by anesthetists. ⋯ In this post hoc analysis of the puncture of the subclavian vein using the landmark technique, we found a significant reduction of puncture attempts and overall mechanical complications. At least 50 punctures seem to be necessary to achieve the end of the learning curve; however, the landmark technique should only be used under special circumstances, when real-time ultrasound is not available. Anesthetists who want to complete their repertoire and learn the landmark technique should always perform a static ultrasound examination before starting the puncture in order to reduce complications due to anatomical variations or thrombosis.

The logistic peculiarities of an emergency maritime location and the frequent additional threat of accidental hypothermia mean that the treatment of medical emergencies at sea are particularly demanding. This article describes the characteristics of emergency medical missions of the German Maritime Search and Rescue Service (DGzRS) as the main provider of non-helicopter-based medical maritime rescue on the seas off the coasts of Germany. ⋯ Although the severity of medical emergencies on the seas off the coasts of Germany was high, the emergency physicians frequently arrived with a considerable delay. There is an urgent need for an effective support of the DGzRS by medical personnel specifically trained for maritime missions.
