Review Case Reports
[Mask ventilation as an exit strategy of endotracheal intubation].
The goal of ventilation in an unprotected airway is to optimize oxygenation and carbon dioxide elimination of the patient. This can be achieved with techniques such as mouth-to-mouth ventilation, but preferably with bag-valve-mask ventilation. Securing the airway with an endotracheal tube is the gold standard, but excellent success in emergency airway management depends on initial training, retraining, and actual frequency of a given procedure in the routine. "Patients do not die from failure to intubate; they die from failure to stop trying to intubate or from undiagnosed oesophageal intubation" (Scott 1986). ⋯ During ventilation of an unprotected airway, stomach inflation and subsequent severe complications may result. Careful ventilation can be performed with low inspiratory pressure and flow, and subsequently with a low tidal volume at a high inspiratory fraction of oxygen. This could be a strategy to achieve more patient safety.

Review
[Residual neuromuscular blockades. Clinical consequences, frequency and avoidance strategies].
Even after administration in routine clinical dosages, muscle relaxants can lead to long-lasting residual blockades which increase the risk of severe postoperative pulmonary complications. Even without the additional effects from analgetics, sedatives or anaesthetics, a partial neuromuscular blockade, which cannot reliably be avoided either by the anaesthetist alone or by the additional use of nerve stimulators (train-of-four [TOF] ratio 0.5-0.9), can cause reductions in the vital capacity and the hypoxic breathing response, as well as obstruction of the upper airway and disruption of pharangeal function. ⋯ If the course of a neuromuscular blockade is continually monitored during the whole anaesthetic procedure using the TOF ratio and not only occasionally at the end, a TOF ratio of 1 measured with an acceleromyograph (e.g. TOF-watch) promises an adequate neuromuscular recovery from the effects of muscle relaxants.

Over a period of 36 months we prospectively documented infectious, neurological and other complications or adverse events occurring during 3,491 peripheral regional anesthesias via a catheter using computer-based data recording. ⋯ Special complications such as infections in peripheral catheter regional anesthesia are rare but can pose severe problems. A close postoperative supervision of all regional catheters has to be ensured under careful consideration of the risk factors for infections and the accompanying symptoms.

[corrected] In the Wuerzburg University level one trauma centre, mobile whole-body multislice computed tomography (MSCT) is used as the primary diagnostic tool in multiple trauma patients. A conventional X-ray unit is not available directly in the resuscitation room of the trauma suite. Three cases are reported to discuss whether state-of-the-art trauma management can be done without conventional radiography. ⋯ Whole-body MSCT is not sufficient as the sole diagnostic tool in hemodynamically instable trauma patients requiring resuscitation and needs to be complemented by a conventional x-ray unit for emergency diagnosis of the chest.

Measurement and assessment of the economic efficiency of clinical departments is still an unresolved, yet important problem in hospital management. Benchmarking with other providers can help to evaluate one's own efficacy in anaesthesia and intensive care services. ⋯ Major factors for profit optimisation are discussed. Special attention is given to the close interaction of surgical, anaesthesiological and intensive care process performance and costs and its impact on benchmarking studies.
