Fatal tracheo-innominate artery fistula after tracheostomy in a patient with Pelizaeus-Merzbacher disease.

Tracheo-innominate artery fistula (TIF) is a serious, life-threatening complication following tracheostomy. We report a fatal TIF in a 15-year-old girl with Pelizaeus-Merzbacher disease. She received a tracheostomy for prolonged translaryngeal intubation due to acute respiratory failure without a trial of noninvasive ventilatory support before intubation.

Effects of direct haemoperfusion through fibres immobilizing polymyxin B and nafamostat mesilate on endotoxaemia in conscious Guinea-pigs.

1. Direct haemoperfusion through a network of fibres immobilizing polymyxin B (PMX-B) is used for the treatment of septic shock, but the mechanism underlying its clinical benefits remains unclear. The aims of the present study were to assess the actions of direct haemoperfusion through fibres immobilizing PMX-B (PMX-DHP) on the effects of exogenously administered endotoxin in conscious guinea-pigs and to examine the difference in the effects of heparin compared with nafamostat mesilate (NM) used as an anticoagulant.

Elimination of 2-arachidonoylglycerol action by direct hemoperfusion through immobilized polymyxin B fibers: an experimental study in conscious guinea pigs.

Direct hemoperfusion through a network of immobilized polymyxin B fibers is used for the treatment of septic shock, but the mechanism underlying the clinical benefits remains unclear. The aims of the present study were to assess the actions of direct hemoperfusion through immobilized polymyxin B fibers on effects of exogenous endotoxin or 2-arachidonoylglycerol in conscious guinea pigs; and to examine the underlying mechanisms. In the present study, colonic motion was monitored continuously by telemetry using a force transducer attached to the taenia caecum, while blood pressure was monitored with a carotid artery catheter.
