Fatal endotracheal tube obstruction due to the ball valve effect.

In patients suffering from pulmonary haemorrhage, or in patients who recently received a tracheostomy, acute occlusion of the endotracheal tube due to a blood clot is a rare, but well-known complication. Acute and complete occlusion of the tube is easily recognisable. There are various methods of removing the obstructive clot, such as using a bronchoscope with forceps, topical thrombolysis, saline lavage and suctioning.

Selective cyclooxygenase-2 (COX-2) inhibition reduces proteinuria in renal patients.

Background: Renoprotection is predicted by the antiproteinuric efficacy of a pharmacological agent. Non-steroidal anti-inflammatory drugs (NSAIDs) interfering non-selectively in the prostaglandin system have strong antiproteinuric potency without reduction of systemic blood pressure. The effect of the selective COX-2 inhibitor rofecoxib in proteinuric patients is unknown, granted recently reported detrimental effects in non-renal patients.

Human albumin and starch administration in critically ill patients: a prospective randomized clinical trial.

Objective: To determine whether intravenous infusion of either human albumin or hydroxyethyl-starch (HES) in hypo-albuminemic critically ill may lead to an increase in colloid osmotic pressure and to a better clinical outcome, i.e. lower mortality and fewer complications, compared to fluid replacement with normal saline.
