Diaphragmatic hernias of the Morgagni type are generally thought to be asymptomatic in adults. This traditional assumption led to a delay in diagnosing a Morgagni hernia as the cause of acute respiratory distress in a chronic schizophrenic man. ⋯ The patient's symptoms were relieved by surgical repair of the hernia. We advise caution before dismissing Morgagni hernias in adults as being long-standing and clinically insignificant.

Case Reports[Acute respiratory failure (ARDS) in a young child after drowning accident: therapy with exogenous surfactant and high frequency oscillatory ventilation].
The adult respiratory distress syndrome (ARDS) in children has a very poor prognosis with a mortality risk of between 55 and 85%, in spite of improvements due to the introduction of positive endexpiratory pressure ventilation. We describe the clinical course of a not yet 3 year-old boy with severe ARDS following near-drowing. Treatment with exogenous surfactant and high frequency oscillatory ventilation, a well-established procedure in neonatology, was responsible for the favorable outcome. The high cost of surfactant therapy, however, is the main limiting factor for this kind of treatment in children beyond the neonatal period, but it may be the last therapeutic resort in the management of severe ARDS.

[Extracorporeal membrane oxygenation in newborn infants and children].
The purpose of this report is to describe our experience with veno-arterial (VA) and veno-venous extracorporeal membrane oxygenation (VV-ECMO) for neonates and children with severe acute respiratory or cardiocirculatory failure. From 1990 to 1994 20 neonates and 12 children were treated at the ECMO center in Graz. Indications for ECMO were acute respiratory failure in 27 patients and cardiocirculatory failure in 5 patients. ⋯ Major complications on ECMO were local and intracerebral bleeding. ECMO is an effective therapy for neonates and children with acute respiratory failure. It is less effective for cardiac support in children after open heart surgery, but the use of heparin-layered ECMO systems might increase the safety of the procedure.

Optimal values for oxygen transport during hypothermia in sepsis and ARDS.
Mild hypothermia (33 degrees C to 35.5 degrees C) is reported to improve oxygenation and survival in patients with lung failure (1). Although hypermetabolism may account for about 50% of the ventilatory demand in ARDS patients, the concept of reducing oxygen consumption (VO2) by lowering metabolic rate, has only recently gained attention (2). Our study was aimed to test whether mild hypothermia established by continuous veno-venous haemofiltration (CVVHF), could optimize values for oxygen kinetics in ARDS patients. ⋯ These results suggest that the inability to achieve optimal values for DO2 and VO2 during mild hypothermia induced by CVVHF could serve as a prognostic sign for fatal outcome. Although oxygen consumption is decreased during hypothermia, hypoxaemia may result due to alterations of the oxygen transport on a cellular basis. The relationship between oxygen transport and temperature during CVVHF therefore deserves further studies.

Case ReportsHow far can we go with permissive hypercapnia? A case presentation and some biased comments with emphasis on maintaining normal haemoglobin level.
The respiratory management strategy of small tidal volume with permissive hypercapnia has been adopted to avoid further aggravation of lung injury due to high airway pressure with some impressive success (1). No consensus, however, has been established in terms of the rate of increase in PaCO2 and its upper limit. ⋯ The fact that PaCO2 may reach a very high level in the clinical setting and the well-known role of haemoglobin (Hb) in buffering CO2 led us to study effects of different Hb levels on pH and haemodynamic changes in response to acute CO2 loading in the blood. We will summarize the case report first with permission of authors (the case report was published in Japanese) (2) and then discuss the studies conducted in our animal laboratory.
