The Univent tube was designed as an alternative to double lumen endotracheal tubes. It is a conventional single lumen tube with an additional small channel within the concave anterior wall portion that houses a movable bronchial blocker used for lung isolation. A thin lumen in the blocker itself allows lung deflation and various ventilatory patterns (oxygen inflow, CPAP, jet-ventilation) in the blocked lung. ⋯ The "blind" insertion of the bronchial balloon carries a high risk of primary malpositioning or secondary displacement that may cause a loss of the lung isolation or even tracheal obstruction. Initial insertion with fiberoptic bronchoscope is therefore required and this device must also be available during the whole period of one lung ventilation. High pressures generated by the bronchial cuff and higher cost than that of double lumen endotracheal tubes are two other factors that limit the use of the Univent tube.

[The injured brain. Basis for hydroelectrolytic and hemodynamic resuscitation].
Brain insult in neurosurgical patients is highly dependent on hydroelectrolytic and haemodynamic disturbances. The magnitude of their effect is related to blood-brain barrier integrity and characteristics of cerebral perfusion pressure. Moderate disturbances in ionic balance or CPP may lead to interstitial oedema or worsening of cerebral ischaemia. ⋯ Normovolaemia and the choice of an appropriate agent for plasma volume expansion are essential. Correction of hypovolaemia is best obtained with (except for packed red cells when necessary) normal saline, 4% human albumin or hydroxyethylstarch. The benefit of utilizing hypertonic electolytic or HES solutions in neurosurgical patients has still to be assessed.

[Training in anesthesiology and surgical intensive care in the United Kingdom].
A review of the training in anaesthetics in the United Kingdom is presented. After basic medical training and obtaining the MB BS qualification, the trainee will usually spend a year outside anaesthetics. Following this period, basic specialist training takes approximately four years, going through senior house officer and registrar grades, leading to the Fellow of the Royal College of Anaesthetist (FRCA) diploma. ⋯ A Certificate of Accreditation is awarded after three years of satisfactory experience in a senior registrar post. The accredited senior registrar is then ready to apply for a consultant vacancy or a senior lecturer's post. Academic appointments are made at registrar and senior registrar levels (lecturers) and consultant level (as senior lecturers and professors).

We report the bench testing of three new anaesthesia ventilators: Flexima (Datex), SA2/RA2 and Cato (Dräger). The test circuit included a two compartment lung model, a pneumotachograph and a pressure gauge. ⋯ Moreover, the tidal volume of the Flexima increased with the fresh gas flow. In spontaneous ventilation inspiratory resistance were low.

[Infectious complications linked to the use of Diprivan. Precaution of administration].
In order to avoid the risk of severe infection by bacterial contamination of propofol, all users of this agent, should be reminded of the required aseptic technique "for the correct use of Diprivan". These points have recently been listed by Zeneca Pharma. They mainly include the following items: 1. ⋯ Disinfection of the ampoule neck or vial stopper using and antiseptic solution before opening, is a strongly measure recommended. 5. Finally, hand washing should be routine, prior to these manipulations. As far as the above mentioned precautions are strictly followed, this anaesthetic agent may be used safely, even in case of prolonged sedation.
