Randomized Controlled Trial Comparative Study
Comparison of fibreoptic-guided intubation through ILMA versus intubation through LMA-CTrach.
We compared the time taken to intubate the trachea of a manikin by fibreoptic-guided intubation through an intubating laryngeal mask airway (ILMA-FOS) with intubation through a laryngeal mask airway CTrach (LMA-CTrach). Forty-two anaesthetists participated in this randomised crossover study. ⋯ Thirty (71%) anaesthetists preferred LMA-CTrach as compared with ILMA-FOS (p = 0.008). We conclude that LMA-CTrach is a suitable alternative to fibreoptic-guided intubation through ILMA for the management of unanticipated failed intubation.

Randomized Controlled Trial
The effect of mannitol on renal function after cardiopulmonary bypass in patients with established renal dysfunction.
The usefulness of mannitol in the priming fluid for cardiopulmonary bypass is uncertain in patients with normal renal function, and has not been studied in patients with established renal dysfunction. We studied 50 patients with serum creatinine between 130 and 250 micromol.l(-1) having cardiac surgery. ⋯ There were no differences between the groups in plasma creatinine or change in creatinine from baseline, urine output, or fluid balance over the first three postoperative days. We conclude that mannitol has no effect on routine measures of renal function during cardiac surgery in patients with established renal dysfunction.
