Splanchnic oxygen transport, hepatic function and gastrointestinal barrier after normothermic cardiopulmonary bypass.
The effect of non-pulsatile, normothermic cardiopulmonary-bypass (CPB) on the splanchnic blood-flow and oxygen-transport, the hepatic function and the gastrointestinal barrier were observed in a prospective observational study in 31 adults undergoing cardiac valve replacement surgery. ⋯ Increased oxygen consumption during CPB may indicate an inflammatory reaction due to the pump beginning in the splanchnic area or a redistribution of the splanchinc blood flow during the CPB. Normothermic CPB does not lead to a significant or prolonged reduction of liver function. Normothermic CPB causes an increase of gastrointestinal permeability. The intestinal barrier function prior to surgery was accountable for the degree of loss of intestinal barrier function following surgery.

Case ReportsAcute airway obstruction in an infant with Pierre Robin syndrome after palatoplasty.
This report describes a complication of post-operative oedema of the palate, tongue and pharynx after a Perko-revised cleft palate repair, which resulted in a life-threatening airway obstruction in an infant with Pierre Robin syndrome. Although infants experiencing airway problems after Wardill-Kilner, von Langenbeck and Furlow palatoplasty have been described, airway complications in a group of Perko-revised repair children have not been previously reported. We speculate that this complication, which occurred in the absence of a history of previous airway problems, is due to prolonged operating time and excessive pressure exerted on the base of the tongue by the Kilner-Doughty retractor. Acknowledgments of this risk permits to identify those patients prior to surgery so that they can be managed appropriately.

Clinical TrialAbolished circadian rhythm of melatonin secretion in sedated and artificially ventilated intensive care patients.
Sleep disturbance is common in intensive care patients. Aside from its unpleasantness, there is a correlation with intensive care unit (ICU) syndrome/delirium. Reasons for sleep deprivation appear to be multifactorial, including the underlying illness, an acute superimposed disturbance, medications, and the ICU environment itself. There are reasons to believe that alterations of the 'biological clock' might contribute. Melatonin secretion is one reflection of this internal sleep/wake mechanism. Melatonin levels are normally high during the night and low during daytime, being suppressed by bright light. ⋯ This study indicates that dyssynchronization of the melatonin secretion rhythm is common in critically ill and mechanically ventilated patients. It could be hypothesized that an impairment of the melatonin rhythm may play a role in the development of sleep disturbances and delirium in intensive care patients, and that melatonin supply could reduce the incidence of these phenomena.

Case ReportsPorcine surfactant (Curosurf) for acute respiratory failure after near-drowning in 12 year old.
This case report describes rapid and persistent improvement after one single dose of porcine surfactant (Curosurf) 0.5 ml/kg(-1) (40 mg/kg) intratracheally for adult respiratory distress syndrome (ARDS) with severe oxygenation failure 8 h after freshwater near-drowning in a 12-year-old girl.

Case ReportsAnaesthesia for cholecystectomy in two non-parturients with Eisenmenger's syndrome.
Eisenmenger's syndrome consists of high pulmonary vascular resistance with reversed or bidirectional shunt at aortopulmonary, ventricular or atrial level. We describe the anaesthetic management of two adult females with Eisenmenger's syndrome admitted for laparoscopic cholecystectomy. ⋯ We used sevoflurane and total intravenous anaesthesia to provide general anaesthesia. Both techniques were tolerated.
