Pain and discomfort arising from the routine care of intubated patients in the ICU is managed by continuous infusion of narcotic and sedative drugs. There is benefit in keeping infusion rates low because lightening sedation improves clinical outcome, but this risks breakthrough pain. Management of this discomfort by bolus administration could permit lower background infusion rates, but the lowest effective bolus dose of sufentanil to achieve this is unknown. ⋯ The effective dose in 90% was 0.15 μg kg during the first 5 days of sedation. There were no adverse effects. A pre-emptive sufentanil bolus can be used to treat anticipated pain in the ICU. Regular and frequent assessments of acute pain and sedation are essential for adjusting the dose, on a case-by-case basis. This strategy may help clinicians to keep background infusions of sedatives and narcotics as low as possible and may improve clinical outcome.

Amino-terminal pro-brain-type natriuretic peptide is known to predict outcome in patients with heart failure, but its role in an intensive care setting is not yet fully established. ⋯ We conclude that NT-pro-BNP is commonly elevated on admission to intensive care, that it increases with severity of illness and that it is an independent predictor of mortality.

Randomized Controlled Trial Multicenter Study Comparative Study
Effects of four different positive airway pressures on right internal jugular vein catheterisation.
The right internal jugular vein (RIJV) is often used for central venous catheterisation in patients undergoing major surgery. The efficacy of this route correlates with the diameter of the vein which can be influenced by airway pressure. ⋯ A PAP of 20 cmH2O seems most suitable for successful RIJV catheterisation in mechanically ventilated patients. It is associated with an increase in cross-sectional RIJV area and CVP, which facilitate cannulation, and results in fewer puncture-related complications. However, meticulous haemodynamic monitoring is needed to avoid hypotension and bradycardia.
