The aim of this study was to evaluate the potential neuroprotective effect of topical head cooling during the first 2 postoperative hours after experimental hypothermic circulatory arrest. ⋯ Topical cooling of the head during the first 2 postoperative hours after experimental hypothermic circulatory arrest does not appear to provide any neuroprotective effect.

The aim of this study is to report a series of spontaneous pneumomediastinum in a population of young, tall, and thin patients with a history of thoracic hyper pressure, and to analyze the assessment required in such patients. ⋯ Spontaneous pneumomediastinum follows alveolar rupture in the pulmonary interstitium. The dissection of gas towards the hilum and mediastinum is produced by an episode of acute high intrathoracic pressure. It affects mostly young people, and this is the case in our series. Endoscopic thoracic assessment may be risky and is not always necessary. Chest CT or esophageal contrast study should be performed in case of diagnostic doubt of esophageal perforation.

Whereas heparin is the most widely used intravenous anticoagulant in the US for the treatment of thromboembolic disease and is a seminal adjunct to many clinical procedures, its use can cause serious adverse events. Heparin-induced thrombocytopenia (HIT) has emerged as one of the most frequently seen complications of heparin therapy and can be a life-threatening immunohematological challenge for patients requiring cardiopulmonary bypass (CPB) with obligatory heparin exposure. Unfortunately, lack of convenient monitoring techniques and the presence of HIT and other comorbidities in the complex patient frequently limits or precludes the use of most alternatives to heparin anticoagulation during CPB. This case report describes the successful use of the celite activated clotting time and high-dose thrombin time, while using the direct thrombin inhibitor Argatroban as an alternative to heparin anticoagulation during CPB in a high-risk patient presenting with type II HIT, end-stage renal failure, and ischemic cardiomyopathy with ventricular fibrillatory arrest.

We reviewed our experience to determine the role of endoscopic airway stents in children with tracheobronchial obstruction. ⋯ Tracheobronchial stenting in children is only rarely needed and often undertaken in dire circumstances. The procedure has led to significant symptomatic benefit in dyspneic children and has enabled ventilator-dependent children to be extubated. Medium-term outlook after stenting with self-expanding metal stents for vascular compression of the airway is encouraging. The long-term outcome remains uncertain, however, and is ultimately influenced by the underlying disease.
