Randomized Controlled Trial Comparative StudySelf-directed deliberate practice with virtual fiberoptic intubation improves initial skills for anesthesia residents.
Fiberoptic intubation is a core skill in anesthesiology. However, this complex psychomotor skill is challenging to learn in the clinical setting. The goal of this study was to evaluate the Virtual Fiberoptic Intubation (VFI) software as an adjunct to the traditional fibreoptic intubation teaching. ⋯ Self-directed practice using VFI software may improve the initial acquisition of fibreoptic intubation skills for anesthesia residents.

Use of pulse pressure variation to estimate changes in preload during experimental acute normovolemic hemodilution.
Acute normovolemic hemodilution (ANH) is an alternative to blood transfusion in surgeries involving blood loss. This experimental study was designed to evaluate whether pulse pressure variation (PPV) would be an adequate tool for monitoring changes in preload during ANH, as assessed by transesophageal echocardiography. ⋯ Changes in preload during ANH were detected by changes in PPV. ∆PPV was superior to ∆PAOP and ∆CVP to this end.
