Observational Study
Fiberoptic assessment of the Laryngeal Mask Airway (Laryseal) position after one hour of positive pressure ventilation: an observational study.
To determine, by fiberoptic endoscope, malpositioning of the Laryngeal Mask Airway (LMA) and other extraglottic devices. ⋯ LMA position may change spontaneously with time during PPV, especially when the LMA position is not optimum at the time of insertion. The LMA should be adequately inserted with all possible measures in cases with general anesthesia and PPV. Fiberoptic assessment of LMA position intraoperatively may be advantageous.

A patient with refractory trigeminal neuralgia (tic douloureux) was treated by intravenous magnesium sulfate successfully. Parenteral magnesium sulfate is an analgesic that expresses its analgesic effects through a noncompetitive blockade of the N-methyl-D-aspartate (NMDA) receptors, which in turns inhibits calcium entry into the cells.
