Pulmonary inflammation is usually associated with increased pulmonary secretion. Even in the absence of cough this secretion is carried by peristalsis and ciliary action to the rima glottidis, whence it overflows into the gastro-intestinal tract. In the acid contents of the stomach the mucus is not dissolved.
Gastric lavage has been successfully used on children in examining the contents of the stomach for tubercle bacilli. By gastric aspiration we have extracted with an alternating vacuum the contents of the stomachs of fasting infants and children for the purpose of typing, though with gastric lavage we were unsuccessful. The method is as follows:
For gastric aspiration there are required: a 50 cm. tube, 4 mm. in diameter, with a 2 mm. bore; a 20 cc. Luer syringe; a Petri dish; 10 cc. of distilled water, and typing serums for the several types of pneumococci.
