Use of the LMA-ProSeal in an experimental pig model -- a potential animal model for laryngeal mask airway research: results of a pilot study.
In light of the increased use of the LMA-ProSeal (P-LMA) it seems desirable to consider the P-LMA for prolonged surgical cases or post-operative ventilation. Long-term use could carry the risk of serious complications. An experimental pig model could be used to gain basic knowledge about long-term use before conducting clinical trails. In this randomized controlled study we tested the hypothesis if prolonged positive pressure ventilation (PPV) with the P-LMA in the pig is possible. ⋯ It was possible to ensure sufficient PPV with the P-LMA in the pig over different periods of time and in different body positions without any complications of airway management. The P-LMA can be used for PPV in the pig for durations of up to 390 minutes. We conclude that investigations into the long-term use of the LMA can be carried out in a pig model.

[Anaesthesia education at german university hospitals: the teachers' perspective -- results of a nationwide survey].
The principle purpose of this study was to collect data on the conditions and practice of anaesthesia education as well as the teaching qualification of consultants at German university hospitals. Based upon the collected data, areas of weakness and strength as well as measures required to improve anaesthesia training are described. ⋯ Due to a lack of a dedicated financial budget for resident training and an increasing economic pressure, "lack of time" and "lack of personnel" are the main factors leading to the situation at German university hospitals that consultants can only spend 14 % of their working hours for teaching purposes despite of sufficient qualification and motivation. As a consequence, novice anaesthetists are faced with the situation to be working without direct and constant supervision after 1 month of training.

[Respiratory sinus arrhythmia as predictor of blood pressure stability during anaesthetic induction in diabetics].
Diabetics with cardiovascular autonomous neuropathy (CAN) can show severe hypotension during the course of anaesthesia. To improve the safety of anaesthesia, pre-operative evaluation of this concomitant disorder is recommended. The conventional test battery described by Ewing and Clarke to diagnose CAN is relatively time-consuming and complex. The aim of this study was to evaluate whether patients at risk could be reliably identified with less diagnostic effort. ⋯ The available results prove the close connection between the pre-operatively measured breadth of respiratory sinus arrhythmia and blood pressure response during anaesthetic induction. Patients at risk of hypotension can be identified reliably and quickly during pre-operative screening with the help of a single, simple test procedure.

Review Case Reports[Risks and complications of epidural neurolysis -- a review with case report].
Racz's minimal invasive epidural catheter procedure, also known as "epidural neuroplasty" is not only utilized in patients suffering from failed spine surgery ("failed back surgery syndrome") but also increasingly applied to non-surgical back pain patients to prevent chronification or deterioration. Its hypothesized principle of action is local epidural lysis of adhesions, neurolysis of vertebral nerve roots and local lavage of proinflammatory mediators by repeated injection of local anesthetics, corticosteroids, hyaluronidase and hypertonic saline solution. However adverse events are well known to occur in epidural neuroplasty. ⋯ Complications related to the procedure itself occur immediately, while complications relating to drug administration show later onset. Within this context, we report a case of severe meningitis with neurologic sequelae in a patient who received Racz catheter-treatment for unspecific low-back pain and provide an overview of the literature on other potential severe complications. As a consequence, we recommend that the Racz catheter procedure as yet should be restricted to controlled clinical trials with rigorous inclusion- and exclusion criteria.
