Randomized Controlled Trial Comparative Study
Randomized comparison of the effectiveness of nasal intubation using a GlideScope video laryngoscope with Magill forceps versus vascular forceps in patients with a normal airway.
The GlideScope® video laryngoscope (GVL) is widely used for nasotracheal intubation in dental and facial plastic surgery. The angle of the Magill forceps is different from that of the GVL blade, which suggests that the Magill forceps are not the ideal forceps for use with the GVL. The purpose of this study was to compare the effectiveness of the Magill forceps vs vascular forceps for nasotracheal intubation using the GVL. ⋯ The total intubation time was significantly less with the vascular forceps (and tube exchanger) than with the Magill forceps. Using vascular forceps also reduced the incidence of epistaxis compared with that using the Magill forceps. Using a tube exchanger and vascular forceps offers advantages over use of Magill forceps when a GlideScope video laryngoscope is used for nasotracheal intubation.

Observational Study
The effect of pericardial incision on right ventricular systolic function: a prospective observational study.
Echocardiographic longitudinal markers of right ventricular (RV) systolic function are commonly depressed after coronary artery bypass graft surgery (CABG) despite an uncomplicated course and good clinical recovery. The exact timing and cause of these changes is unknown. The aim of this observational study was to monitor echocardiographic markers of RV systolic function intraoperatively during CABG. We used angle-independent speckle tracking to measure the primary endpoints of tricuspid annular plane systolic excursion (TAPSE) and tricuspid annular systolic velocity (S') before and after pericardiotomy. ⋯ Pericardial opening and suspension had no significant effect on the indices of RV systolic function derived from speckle tracking or colour tissue Doppler.
