Review[What will jugular bulb oxygen saturation monitoring tell?].
Global cerebral oxygenation can be measured by means of a catheter introduced in the internal jugular vein and placed retrograde in the jugular bulb. The measure of oxygen saturation sampled from the jugular vein (SjvO2) depends on cerebral metabolism and blood flow. This parameter describes the relative balance between oxygen delivery to the brain and oxygen consumption by the brain. ⋯ Besides this, elevated SjvO2 should not be universally interpreted as hyperaemia. Instead, the presence of an elevated SjvO2 is a heterogeneous condition. Increased SjvO2 may be alarming prognostic indicators that carry important implications for comatose patients management.

Randomized Controlled Trial Clinical Trial[Endotracheal tube cuff pressure. Monitoring during general anesthesia].
To value changes of endotracheal tube cuff pressure during anaesthesia with N2O, using standard tubes or Brandt-system tubes. ⋯ Brandt's double cuff-tubes (G2) succeed in avoiding uncontrolled increase of cuff-pressure during anaesthesia with N2O. Standard low-pressure tubes (G1) shown increase of cuff pressure during anaesthesia with N2O which is absent using no N2O (G3).
