Nonsurgical drainage of the gallbladder incident to a complete investigation of the gatro-intestinal tract has heretofore required several hours. With the improved tube and altered technic, it requires only one-half hour.
DESCRIPTION OF THE TUBE
The olive: The fenestrations and lumen are larger, the lumen extending throughout the entire olive; all sharp edges are rounded, polished and gold plated to prevent discoloration and corrosion.The tube: The overall diameter of the tube and of the olive are thus approximately equal. The proximal end attachments are omitted as unnecessary. An all rubber, 3 ounce syringe with a hard rubber or bakelite cannula is all that is necessary. It facilitates the method of obtaining material for culture.
The following is an outline of the technic to be used.Time: Preferably 9 a. m., on a fasting stomach.
Hypertonic solution of sulphate of sodium, magnesium, potassium and calcium warmed.
