Case Reports[Spontaneous intracerebral haemorrhage secondary to congenital factor XIII deficiency].
Deficiency of coagulation factor XIII is a rare anomaly. The risk of intracranial haemorrhage is particularly high at any age, either spontaneously or during minor trauma. We report a case of spontaneous intracerebral haemorrhage in a child carrying a known deficiency of factor XIII.

[Ultrasound evaluation of the nasogastric tube position in prehospital].
To assess the feasibility and actual performance of ultrasound control in verification of the correct positioning of a nasogastric tube in pre-hospital settings. ⋯ The ultrasound test performed in our study to verify correct positioning of a nasogastric tube is feasible in a pre-hospital setting. This technique is rapid and non-irradiating and is more sensitive and specific than the syringe tests commonly used in pre-hospital settings, and it may be performed in place of the latter tests.

This article provides a synthesis of physiology and pathophysiology of the cardiovascular system and briefly presents the principles of regulation at the level of the whole organism and regional circulations. Decision algorithms, based on knowledge of physiology and pathophysiology are proposed. Their goal is to contribute to the improvement of cardiopulmonary bypass practice.

Case Reports[Oxygenator thrombosis without heparin resistance in polycythemia vera].
A 55-year-old male with a history of positive HIV serology and polycythemia vera underwent coronary artery bypass graft surgery with normothermic extracorporeal circulation. Following heparin administration the activated clotting time (ACT) was 633 seconds (Hemocron with kaolin). Lower than expected arterial and venous oxygen partial pressures together with high pressure (350 mmHg) in the arterial line upstream of the oxygenator were observed. ⋯ Electronic microscopic examination of the oxygenator membrane and thermic exchanger revealed fibrin and platelet deposits. Similar cases are described in the literature during polycythemia vera. Therefore the prevention might be a preoperative treatment with antiplatelet therapy in polycytemia vera.

[Anaesthesia and vasomotor tone during CPB: intravenous anaesthetics].
Anaesthesia during CBP is frequently provided using intravenous anaesthetic drugs, particularly propofol. The effects of the different drugs have been studied during CPB. These drugs have an arterial and venous vasodilator effect during CPB which is dose dependent and is more pronounced for propofol. High doses of propofol or thiopental reduce cerebral blood flow but provide no additional neurological protection.
