Case Reports[Preliminary experience with dexmedetomidine treatment of confusional state and hyperadrenergic states at an intensive care unit].
Delirium (confusion) is an acute, reversible and fluctuating compromise of awareness and cognitive function, a state that can increase morbidity and mortality. We describe four patients with delirium associated with agitation and hyperadrenergic states refractory to haloperidol but responsive to dexmedetomidine.

[Adipose tissue within peripheral nerves. Study of the human sciatic nerve].
To describe the distribution of intraneural adipose cells in relation to nerve fascicles in a portion of peripheral nerve usually involved in accomplishing an anesthetic blockade of a lower extremity. ⋯ The adipose tissue inside a nerve surrounded the fascicles to form adipose sheaths that separated the fascicles from one another. The thicknesses of these adipose sheaths varied from one fascicle to another. Cells join to make it possible to create a compact adipose sheet that can delay the diffusion of local anesthetic injected near a nerve and that can therefore interfere with the characteristics of an anesthetic blockade.

Case Reports[Acute contralateral hemothorax after cannulation of the left subclavian vein for hemodialysis].
Contralateral hemothorax after subclavian vein cannulation is a rare complication of this procedure. We report one case of acute contralateral hemothorax due to perforation of the superior vena cava during left subclavian vein cannulation for hemodialysis. ⋯ Chest pain began immediately after perforation and was followed, a few minutes later, by hemodynamic instability. The signs and symptoms described in this report may serve to warn of the possibility of this complication.

Randomized Controlled Trial Comparative Study Clinical Trial[Metamizol versus propacetamol: comparative study of the hemodynamic and antipyretic effects in critically ill patients].
To compare the antipyretic and hemodynamic effects of metamizol and propacetamol in critically ill patients with fever. ⋯ Both metamizol and propacetamol are effective antipyretics at the doses tested. However, both have adverse hemodynamic side effects that may be poorly tolerated by critically patients.
