Lung ultrasound imaging can be used to evaluate pulmonary water content and pulmonary consolidation in ICU patients, but data from neurocritical care are lacking. ⋯ In neurocritical care, the use of lung ultrasound allows detection of increased lung water content when more than three 'B-lines' are present within the same lung field. This is associated with a reduction in PaO2/FiO2 ratio. Lung ultrasound can be used to diagnose pulmonary consolidation with an accuracy similar to the chest radiograph.

Coma is a state of profound unresponsiveness that can occur as a serious perioperative complication. The study of risk factors for, and sequelae of, postoperative coma has been limited due to the rarity of the event. ⋯ This is the largest study of postoperative coma ever reported and will be useful for determining risk of coma of more than 24 h duration when evaluating an unresponsive patient following surgery. Data on prognosis will aid medical and ethical decision-making for the comatose surgical patient.

Balanced hydroxyethyl starch (HES) solutions with a molecular weight of 130 kDa (tetrastarches) are frequently used in clinical practice. These solutions are derived either from waxy maize or potato starch and they are not bioequivalent. ⋯ Bolus infusion of balanced 6% wt/vol tetrastarches augments mucosal capillary perfusion. Pulmonary inflammation in sepsis is differentially influenced by tetrastarches produced from different raw materials.
