Ir. Selby et P. Morris, INTERMITTENT POSITIVE VENTILATION THROUGH A LARYNGEAL MASK IN CHILDREN - DOES IT CAUSE GASTRIC DILATATION, Paediatric anaesthesia, 7(4), 1997, pp. 305-308
After obtaining Ethics Committee approval and informed consent, sixty
children, ASA Grade 1 or 2 and aged six months to ten years, were rand
omly allocated to receive intermittent positive pressure ventilation t
hrough either a laryngeal mask or a tracheal tube. Inflation pressures
were maintained below 20 cm H2O, and gas aspirated from the stomach v
ia an orogastric tube over a one h period. No large volumes were aspir
ated and no differences were detected between the groups. We conclude
that healthy children over the age of six months can be safely ventila
ted through the laryngeal mask airway without gastric distension.
