Randomized Controlled Trial
Comparison of two sizes of GlideScope® blades in tracheal intubation of infants: a randomised clinicaltrial☆.
The appropriate size of GlideScope® blade for tracheal intubation in neonates and premature infants has not been established. We evaluated the impact of the size of the GlideScope® blade on the time taken for intubation in infants weighing 2.5-3.6 kg. ⋯ KCT 0003867.

Studies of intraoperative hypotension typically specify a blood pressure threshold associated with adverse outcomes. Such thresholds are likely to be study-biased, investigator-biased, or both. We hypothesised that a newly developed modelling method without a threshold, which is biologically more plausible than a threshold-based approach, would reveal a continuous association between exposure to intraoperative hypotension and adverse outcomes. ⋯ Intraoperative hypotension appears to have a graded association with postoperative myocardial injury and mortality, with depth appearing to contribute more than duration.

Observational Study
Videolaryngoscopy as a first-intention technique for tracheal intubation in unselected surgical patients: a before and after observational study.
Using a Macintosh-style videolaryngoscope as a first-intention device for tracheal intubation of unselected patients in the operating room has not often been studied. We hypothesised that using a Macintosh-style videolaryngoscope as a first-intention device is associated with an increased proportion of easy tracheal intubation. ⋯ Using a Macintosh-style videolaryngoscope as a first-intention device for tracheal intubation in the operating room was associated with a significant increase in the proportion of easy tracheal intubation, compared with use of the standard Macintosh laryngoscope.
