Case Reports
[Accidental intoxication with unlabeled, generic transdermal fentanyl patches caused by insufficient instruction].
A somnolent 78-year-old male patient was brought to our emergency room by an ambulance with the presumptive diagnosis of stroke. Cranial computed tomography provided no evidence. On the intensive care unit of the neurosurgical department the patient was completely undressed. ⋯ Under the presumptive diagnosis of an opioid intoxication by a transdermal therapeutic system naloxone was infused over 3 days. The patient reported after rapidly awaking that fentanyl patches had been prescribed by his family practitioner the day before. The patient recovered without any sequelae.

Clearly defined professional roles have the advantage that team members know what they are expected to do and what their expectations of other professional groups are. For the definition of roles a distinct number of interactions between persons are a prerequisite. In a typical operations room (OR) team members are not constantly involved and are often exchanged. Interactions between personnel are not strong enough to fulfil the designing process of role shaping. In this study the possible substitution of defined roles by a distinct professional culture in an OR was studied. ⋯ It is concluded that in this analysis the role definition was not clear. Optimization is therefore possible which could reduce conflict potential and contribute to a higher productivity.

Comparative Study
[Preclinical transtracheal emergency ventilation. Animal experimental comparison of two techniques].
Prehospital transtracheal ventilation via a needle cricothyroidotomy may be lifesaving in cannot-intubate-cannot-ventilate situations. A self-made device consisting of a three-way stopcock placed between a transtracheal airway catheter and an oxygen supply was constructed and the effectiveness of the device was compared with a hand-triggered emergency jet generator in animal experiments. ⋯ The efficacy of the self-made device during the experiment was comparable with the efficacy of the hand-triggered emergency jet injector.

Case Reports
[Vasopressin as a rescue vasopressor agent. Treatment of selected cardiogenic shock states].
Vasodilatory shock is the most common form of shock in the critically ill patient. As a consequence of overwhelming and prolonged mediator production, vasodilatory shock can be the common final pathway of primary non-vasodilatory shock (e.g. cardiogenic or hypovolemic shock). ⋯ The hemodynamic effects of AVP were comparable to those AVP-induced alterations described in septic shock and seem to be predominantly mediated by potent vasoconstriction and the facilitated reduction of higher, potentially toxic catecholamine doses. Thus, an AVP-induced decrease in heart rate and pulmonary arterial pressures may be particularly beneficial in patients with impaired cardiac function.
