Supraglottic jet ventilation assists intubation in a Marfan's syndrome patient with a difficult airway.

A 37 year old woman with Marfan's syndrome underwent an elective gynecologic procedure. Mask ventilation was not difficult but initial direct laryngoscopy showed no view of the glottic opening. The patient's trachea was quickly and successfully intubated using a supraglottic jet ventilation technique.

Antifreeze ingestion by dogs and rats: influence of stimulus concentration.

Ingestive responses of 50 rats and 4 gastric-cannulated dogs to ethylene glycol-based antifreeze (AF) were found to be inversely related to concentration. The antifreeze was never preferred to water. Do thirsty animals that encounter weak AF solutions drink them solely for their water content, water-related oral tactile sensations, or both, being inadvertently poisoned in the process?
