[The preventive minitracheotomy as support in difficult intubations: a proposition. Description of a clinical case].

The authors suggest preventive minitracheotomy as a support technique in difficult endotracheal intubation, and report their experience in a case of surgical operation to remove a bony neoformation of C1 and C2 posterior arcs. Endotracheal intubation, difficult because no part of the glottis could be seen, was made possible by preventive minitracheotomy. In this way sedation, myorelaxation and excellent oxygenation during following manoeuvre that resulted atraumatic, were obtained. The small cannula of minitracheotomy was maintained closed during the operation and open for 24 hours thereafter to prevent obstructive complications. It was then removed.

A new method for separate lung ventilation.

Separate lung ventilation is obtained with selective intubation of the main bronchus by an appropriate cuffed tube inserted through a standard orotracheal tube. Ventilation is carried out separately through the bronchial tube on one side and the residual tracheal tube lumen on the other side. This method, used in 144 patients, greatly simplifies the technique of bronchial intubation and offers many advantages over commercially available double-lumen tubes.

A continuous flow intermittent mandatory ventilation with continuous positive airway pressure circuit with high-compliance reservoir bag.

Unstable inspiratory pressure may reduce the benefits of intermittent mandatory ventilation and impose a greater work of breathing than some patients can tolerate. The authors evaluated a continuous flow intermittent mandatory ventilation with continuous positive airway pressure apparatus provided with a 10-L high compliance reservoir bag, separated from the ventilator circuit by a one-way valve. A pulmonary simulator was tested to generate a wide range of inspiratory peak flow rates. Pressures and flow rates were examined in different sections of the system, using PEEP levels up to 15 mm Hg and different fresh gas flow rates. The circuit offers many advantages, particularly considering the low inspiratory pressure drop and the low fresh gas flow rates needed for optimal function.

Functional evaluation of a CPAP circuit with a high compliance reservoir bag.

Continuous positive airway pressure is widely used in the treatment of ARF and an evaluation of the systems is important. The authors used an artificial model to test a continuous flow system with a high compliance reservoir bag. The results confirm that the system is effective in maintaining positive pressure stability within a wide range of inspiratory peak flow rates, even when a low fresh gas flow rate is employed. Nevertheless, rebreathing of expired gases is possible and may be noticeable at high expiratory flow rates, caused by the high compliance of the reservoir bag.

[Myasthenia gravis. Indications, aims and methods of intensive therapy].

Some recent views on pathophisyology of "myasthenia gravis" are presented. The Authors explain the typical damage of myasthenia gravis, i.e. the progressively reduced muscolar function on the basis of an autoimmune derangement affecting the motor-end plates. The most commonly used types of treatment, both medical (i.e. antiChE, A.C.T.H., steroids and immunodepressant drugs) and surgical (thymectomy) are reviewed. The very important role of Intensive Care for the treatment either of myasthenia gravis "per se" or of possible consequences of some drugs (A.C.T.H. steroids) is also stressed. Finally the Authors present their results about their experience on 36 patients affected by myasthenia gravis and admitted to I.C.U. once (29 patients) or twice or more (7 patients). The Authors describe some practical problems presented by patients during their stay in I.C.U.
