Guidelines support the use of a restrictive strategy in blood transfusion management in a variety of clinical settings. However, recent randomized controlled trials (RCTs) performed in the perioperative setting suggest a beneficial effect on survival of a liberal strategy. We aimed to assess the effect of liberal and restrictive blood transfusion strategies on mortality in perioperative and critically ill adult patients through a meta-analysis of RCTs. ⋯ According to randomized published evidence, perioperative adult patients have an improved survival when receiving a liberal blood transfusion strategy.

Case Reports
Printed three-dimensional airway model assists planning of single-lung ventilation in a small child.
Single-lung ventilation in infants and small children is challenging because suitable sizes of double-lumen cuffed tracheal tubes are not available. A 6-yr-old child required pulmonary saline washout for primary alveolar proteinosis, and therefore needed sequential single-lung ventilation in order to achieve safe oxygenation. Before undertaking this potentially hazardous procedure, we practised bronchial intubation on an anatomical model of her airway constructed from computed tomography (CT) data. ⋯ Three-dimensional printing of a model of the airway of a small child aided planning of bronchial intubation and single-lung ventilation. Three-dimensional printing of airway structures may have wider application in anaesthesia practice.

Randomized Controlled Trial
Effect of acute cigarette smoking on gastric contents in regular smoker volunteers. A prospective randomized cross-over study.
The authors sought to assess the effect of acute smoking on gastric contents in regular smoker volunteers. The primary endpoint was the variation in antral area during the 120-min study period after cigarette smoking. ⋯ NCT 02080598.
