Air-Q versus LMA Fastrach™ for fiberoptic-guided intubation: A randomized cross-over manikin trial.

Introduction: Airway management is still a major cause of anesthesia-associated morbidity and mortality. Supraglottic devices are recommended in difficult airway management guidelines. The aim of this study was to compare the performance of the Air-Q and the LMA Fastrach™ for fiberoptic guided tracheal intubation.

[Effectiveness of the GlideScope video laryngoscope in a case of unexpected difficult airway due to lingual tonsil hypertrophy].

Lingual tonsil hypertrophy can cause varying degrees of airway obstruction and is considered a risk factor for difficult mask ventilation and tracheal intubation. We report a case of unexpected difficult airway in a patient with unknown lingual tonsil hypertrophy that was solved with the use of the GlideScope video laryngoscope.

Nitrate reduction in tendrils of semi-leafless pea.

The recessive gene af produces a modification of Pisum sativum L. leaf morphology, where leaflets are replaced by tendrils. Previous reports have suggested that tendrils may contribute to plant growth in a similar way to flat leaf structures, but these reports have been restricted to carbon metabolism.

[The effects of carbonation on 2% mepivacaine in epidural anesthesia].

Objectives: To evaluate the clinical effects of 2% carbonated mepivacaine in arthroscopic surgery of the knee.

Patients And Method: Thirty patients were enrolled in this prospective, double-blind study, and randomly assigned to two groups to receive 2% mepivacaine plus saline (group I, n = 15) or 2% mepivacaine plus bicarbonate soda. The alkalinized solution was prepared by adding 0.
