Short, medium, and long tubes are used to pass through the nose into the stomach or small intestine. They range from 10F to 20F in size and 105-120 cm in length. Tubes are sterilized using gamma ray irradiation, ethylene oxide gas, or boiling. Tubes are inserted by measuring the distance from the nose to earlobe and sternum to determine the proper length, lubricating the tube, cleaning the nostril, and slowly advancing the tube while the patient is in a sitting or Fowler's position. Tubes are used for therapeutic purposes like decompressing the gastrointestinal tract or diagnostic purposes like gastric juice analysis. Complications can include sinusitis, epistaxis, otitis media

COMPONENTS

7. Gamma rays irradiation at the bhabha
atomic research
Ethylene oxide gas sterilization
Boiling

9. Determine the length of tube to be inserted
Measure distance from tip of nose to earlobe&
to xyphoid process of sternum
 Tube:lubricated with sterile paraffin or jelly
Nose:wider nostril selected
Nostril cleaned with pledgent of cotton wool
Moistened with savlon in water
Patient:sitting position /fowler’s position
When patient is lying ,head should be flexed by one hand
Tip-passed along nasal septum & horizontally along floor of nose

12. FIXING THE TUBE:
In unconscious patient:
•By magill’s endotracheal tube
Duodenal Aspiration:
•Passed upto 55cm
•Patient lie on right side
•Tube advanced slowly at rate of
1cm/min for 20 min

13. Gastrostomy:

14. CARE OF TUBE:
If tube gets blocked inject 10 ml air /tap water
Kept for more than 2 days-removed every 48 hrs
