ReviewStapled versus handsewn methods for colorectal anastomosis surgery.
Randomized controlled trials comparing stapled with handsewn colorectal anastomosis have not shown either technique to be superior, perhaps because individual studies lacked statistical power. A systematic review, with pooled analysis of results, might provide a more definitive answer. ⋯ The evidence found was insufficient to demonstrate any superiority of stapled over handsewn techniques in colorectal anastomosis, regardless of the level of anastomosis.

Inhaled budesonide (BUD) is available in a range of doses for treating chronic asthma. ⋯ Budesonide exhibits a clinically significant dose response effect for improvement in FEV1 in severe asthma and reduction of exacerbations in moderate to severe asthma. No significant dose dependent improvements in FEV1, PEFR or symptoms are evident in non-oral steroid treated asthmatics with mild to moderate disease. Dose dependent alterations in sensitive measures of hypothalamic-pituitary-adrenal function were evident but the clinical significance of these changes is unclear.

ReviewPreoxygenation for tracheal suctioning in intubated, ventilated newborn infants.
Endotracheal suctioning for mechanically ventilated infants is routine practice in neonatal intensive care. However, this practice is associated with serious complications including lobar collapse, pneumothorax, bradycardia and hypoxemia. Increasing the inspired oxygen immediately prior to suction (preoxygenation) has been proposed as an intervention to minimise the risk of complications. ⋯ No recommendations for practice can be confidently made from the results of this review. Although preoxygenation was shown to decrease hypoxemia at the time of suctioning, other clinically important short and longer-term outcomes including adverse effects were unable to be assessed. Further studies are needed to adequately assess the effects of this widely practiced procedure.

Phototherapy is used to treat newborn infants with hyperbilirubinaemia. Fibreoptic phototherapy is a new mode of phototherapy which is reported to lower serum bilirubin (SBR) while minimising disruption of normal infant care. ⋯ Fibreoptic phototherapy has a place in the management of neonatal hyperbilirubinaemia. It is probably a safe alternative to conventional phototherapy in term infants with physiological jaundice. No trials have been identified which support the widely-held view that fibreoptic devices interfere less with infant care or impact less on parent-child bonding.

ReviewCorticosteroids for preventing relapse following acute exacerbations of asthma.
Acute asthma is responsible for many emergency department visits annually. Between 12-16% will relapse to require additional interventions within two weeks of ED discharge. Treatment of acute asthma is based on rapid reversal of bronchospasm and reducing airway inflammation and this review examines the evidence for using systemic corticosteroids to improve outcomes after discharge from the ED. ⋯ A short course of corticosteroids following assessment for an acute exacerbation of asthma significantly reduces the number of relapses to additional care and decreases beta-agonist use without an apparent increase in side effects. Intramuscular corticosteroids appear as effective as oral agents.
