Specially organised stroke units can be a ward or team that exclusively manages stroke patients (a dedicated stroke unit) or a ward or team that provides a generic disability service (a mixed assessment or rehabilitation unit). ⋯ Stroke patients who receive organised inpatient care in a stroke unit are more likely to be alive, independent, and living at home one year after the stroke. The apparent benefits are not restricted to any particular sub-group of patients or model of stroke unit care. No systematic increase was observed in the length of inpatient stay.

ReviewPostoperative caffeine for preventing apnea in preterm infants.
Growing ex-preterm infants who undergo general anesthesia for surgery at about term-equivalent age may have episodes of apnea, cyanosis and bradycardia during the early postoperative period. Caffeine treatment given at the time of operation might prevent these episodes. ⋯ Implications for practice. Caffeine can be used to prevent postoperative apnea/bradycardia and episodes of oxygen desaturation in growing preterm infants if this is deemed clinically necessary. In view of the small numbers of infants studied in these trials and uncertainty concerning the clinical significance of the episodes, caution is warranted in applying these results to routine clinical practice. Implications for research. There is a need to determine which infants might benefit most by this treatment. Studies confined to those most at risk of apnea (prior history, younger postmenstrual age) and those that might require mechanical ventilation (chronic lung disease) would be of value.

Mannitol is sometimes dramatically effective in reversing acute brain swelling, but its effectiveness in the on-going management of severe head injury remains open to question. There is evidence that in prolonged dosage mannitol may pass from the blood into the brain, where it might cause reverse osmotic shifts that increase intracranial pressure. ⋯ There are insufficient data to recommend one form of mannitol infusion over another. Mannitol therapy for raised ICP may have a beneficial effect on mortality when compared to pentobarbital treatment. ICP-directed treatment shows a small beneficial effect compared to treatment directed by neurological signs and physiological indicators. There are insufficient data on the effectiveness of pre-hospital administration of mannitol to preclude either a harmful or a beneficial effect on mortality.

ReviewProphylactic syntometrine versus oxytocin for delivery of the placenta.
The routine prophylactic administration of an oxytocic agent is an integral part of active management of the third stage of labour. These agents help prevent postpartum haemorrhage. ⋯ The use of the combination preparation syntometrine (oxytocin and ergometrine) as part of the routine active management of the third stage of labour appears to be associated with a statistically significant reduction in the risk of postpartum haemorrhage when compared to oxytocin where blood loss is less than 1000ml. No difference was seen between the groups using either five or 10 international units for blood loss equal to or greater than 1000 millilitres. This needs to be weighed against the more common adverse effects associated with the use of syntometrine.

ReviewHolding chambers versus nebulisers for beta-agonist treatment of acute asthma.
In acute asthma inhaled beta-agonists are often administered to relieve bronchospasm by wet nebulisation, but some have argued that metered-dose inhalers with a holding chamber (spacer) can be equally effective. In the community setting nebulisers are more expensive, require a power source and need regular maintenance. ⋯ Metered-dose inhalers with holding chamber produced outcomes that were at least equivalent to nebuliser delivery. Holding chambers may have some advantages compared to nebulisers for children with acute asthma.
