Types of Tubes Used
- Ryle’s tube (Nasogastric tube): Old Ryle’s tube was a red rubber tube with one bead of metal at the tip. Now plastic Ryle’s tubes are in use they are made polyvinyl chloride
- Ewald tube: In an emergency, using this single-lumen tube with several openings at the distal allows you to aspirate large amounts of gastric contents quickly
- Levacuator tube: This tube has two lumens. Use the larger lumen for evacuating gastric contents, the smaller for instilling an irritant
- Edlich tube: This single lumen tube has four openings near the closed distal tip. A funnel or syringe may be connected at the proximal end. Like the Ewald tube, the Edlich tube lets you withdraw large quantities of gastric contents quickly.
Description of Ryle’s Tube
- They are made up of polyvinyl chloride
- Size caliber ranges from 10 to 20 F
- Length is 105-125 cm long
- Tip it is blend to avoid trauma
- There are three or four metal beads because:
- Metal is radiopaque, so radiologically we can confirm the position of the tip
- They facilitate the passage of the tube by action of the gravity and also facilitate swallowing due to their weight.
- There are multiple opening at different levels.
- There are four marking in the tube:
- 40 cm from the tip to mark cardioesophageal junction
- 50 cm from the tip (tip in stomach) 60 cm from the tip (tip at pylorus)
- 65 cm from the tip (tip in the duodenum)
- Base: It is provided with one cork.
- Size of its lumen is just adequate to adopt the nozzle of the syringe.
