The development of adult respiratory distress syndrome (ARDS) complicates the treatment of patients with severe head injury, since special therapeutic strategies for both conditions might lead to a "conflict of interest". We report on the intensive care treatment of a young man who suffered severe brain injury (Glasgow Coma Scale = 3) due to a traffic accident and simultaneously developed ARDS from the aspiration of gastric content. We performed extensive monitoring of cerebral hemodynamics and metabolism (intracranial pressure measurement, jugular bulb oxymetry, estimation of arterial-jugular bulb lactate concentration difference) to prevent cerebral hypoxia and to control cerebral hyperemia. ⋯ After withdrawing the analgo-sedation the patient's vigilance rose continuously. The patient was transferred to a rehabilitation ward 33 days after admission to the intensive care unit. The combination of ARDS and severe brain injury needs special treatment, which includes extensive monitoring techniques to find a solution for therapeutic conflicts.

Transient neurologic symptoms (TNS) after spinal anesthesia (SPA) is defined as back pain with radiation or dysesthesia in the buttocks, thighs, hips and calves, occurring within 24 h after recovery from otherwise uneventful SPA. The symptoms last for about 1-3 days but neurophysiologic evaluation does not show pathologic findings. The type and the preparation of the local anesthetic drug (baricity, concentration, additives or preservatives) are most often discussed as the underlying cause of TNS. ⋯ Prilocaine and bupivacaine for SPA are associated with less TNS than lidocaine and mepivacaine. For the other local anesthetics there were not enough comparative trials to give conclusive recommendations.

The action profile of succinylcholine is unmatched even 50 years after its introduction into anaesthestic practice. This is probably why succinylcholine, despite its many and partly life-threatening side-effects, is still considered to be indispensable by many anaesthetists and emergency doctors. The main indication for succinylcholine--the facilitation of endotracheal intubation in patients considered to be at an increased risk of aspiration of gastric fluid, e.g. patients undergoing a Caesarean section or presenting with an ileus--remains undisputed. ⋯ In the case of an expected difficult airway no muscle relaxant should be given, because severe hypoxaemia in these patients probably can only be prevented by a professional airway management. Succinylcholine is no longer an option in elective paediatric anaesthesia. The drug, however, retains its value in critical situations where a rapid onset but a short duration of action is of prime importance.

Clinical Trial
[Coronary bypass operation with complete median sternotomy in awake patients with high thoracic peridural anesthesia].
High thoracic epidural anesthesia (TEA) combined with general anesthesia is increasingly being used for coronary artery bypass grafting (CABG) with extracorporeal circulation. Recent developments in beating heart techniques have rendered the use of TEA alone in conscious patients possible and have been reported for single-vessel beating heart CABG via lateral thoracotomy. For multi-vessel revascularization the heart is usually approached via median sternotomy, therefore the use of TEA alone was applied in awake patients with multi-vessel coronary artery disease who underwent CABG via median sternotomy. ⋯ We could demonstrate that the use of TEA alone for CABG via median sternotomy was feasible and produced good results. High patient satisfaction in our small and highly selected cohort could be reported. Nevertheless, randomized controlled trials in large cohorts are mandatory to definitively evaluate the role of TEA alone in cardiac surgery.
