Randomized Controlled Trial Clinical Trial
[The effect of theophylline on the mucociliary clearance function in ventilated intensive care patients].
Mucociliary clearance represents an important protective mechanism of the upper and lower respiratory tracts whereby inhaled particles and micro-organisms are removed from the tracheobronchial system. In incubated intensive care unit (ICU) patients, impaired ciliary function and mucus transport are associated with pulmonary complications [9]. Some authors have shown that theophylline increases mucus transport in healthy subjects and patients with chronic bronchitis [8, 16, 31, 36]. ⋯ CONCLUSIONS. Theophylline at therapeutic concentrations improves bronchial mucus transport in intubated ICU patients. The increase in BTV may be associated with severe tachycardia, and therefore routine application cannot be recommended.

Fournier's gangrene is a necrotising soft-tissue infection of the scrotum and perineal region caused by gram-negative and gram-positive Enterobacteriaceae. The disease is characterised by its unique appearance, its speed of onset, and its high mortality. CASE REPORT. ⋯ The treatment should include immediate radical surgical debridement, i.v. administration of broad-spectrum antibiotics, and cardiopulmonary support. CONCLUSION. The dramatic course of Fournier's gangrene requires early recognition, extensive surgical debridement, as well as intensive care treatment in order to prevent irreversible septic shock.

Intrinsic positive end-expiratory pressure (PEEPi) occurring during mechanical ventilation depends on expiratory time constants, expiratory volume and expiration time as well as on external flow resistance (tubes, valves, etc.). It is not routinely determined in mechanically ventilated patients, but it is necessary to optimize respirator settings. The aim of the present study was the validation of an automated PEEPi determination method implemented in the respirator EVITA (Drägerwerke, Lübeck) in mechanically ventilated patients with acute lung failure. ⋯ Unfortunately, PEEPi measurement of the EVITA can only be performed during controlled and not during assisting (PSV, BIPAP etc.) ventilation. Optimal respirator settings require a knowledge of PEEPi (i.e., adaption of external PEEP for lowering the work of breathing in COPD patients or prolongation of the expiratory phase to avoid unwanted side effects of an occult PEEPi on the circulation).

The hospital nursing staff represents a distinct group of cardiopulmonary resuscitation (CPR) providers. Differences in the success rates of resuscitation attempts inside or outside the hospital seem to be attributable to the skill of the various rescuers. Whereas the definite success rate for prehospital resuscitation is 7%, the corresponding rate for in-hospital settings is 15%. ⋯ Indeed an increasing rate of successful resuscitations inside the hospital (up to 27%) has been reported in the literature. In consequence of our findings, refresher courses in specific CPR techniques must be demanded, which should be made obligatory for nursing staff every 2 years. Qualified nursing personnel routinely trained in CPR and supported by effective hospital logistics is essential if the life-saving benefits of modern CPR are to be provided to our patients.
