Oesophagostomy Tube Feeding
An oesophagostomy tube (O-tube) is a small rubber tube that enters a surgical incision on the side of the neck. Placement of the tube through this incision allows food to enter the oesophagus and then flow down into the stomach. The tube is not placed directly into the stomach.
The oesophagostomy tube is used in cats with diseases that cause long-term anorexia (failure to eat) or when upper respiratory disease, jaw fractures or other mouth injuries are present that prevent eating.
How do I feed my cat through the tube?
We recommend using Eukanuba Max Cal canned or Hills AD diet which is specifically formulated to meet the cat's nutritional needs; it should not cause vomiting or diarrhoea. To feed your cat follow these steps:
- Feed using Eukanuba Max Cal canned diet
- Using the syringes provided, inject 3ml of water into the tube to flush it clean.
- Remove the screw cap and give meal as per requirement below. It is helpful to inject the food slowly, about 1ml per second, and to elevate your cat's front feet so the food goes easily into the stomach. Replace the cap in the tube.
- Administer any medications as per instructed.
- When the food has been injected follow with 5ml of tap water through the port so food does not remain in it.
- Any remaining food should be stored in the refrigerator. Before the next feeding, it should be warmed to body temperature under hot tap water or in a microwave oven. If you heat it in a microwave oven, be sure to thoroughly mix the contents prior to feeding because of uneven heating. Also, always check the temperature prior to feeding to be sure that the food is not too hot.
- Return to your vet every 5-7 days for a dressing change.
When and how is the tube removed?
Patience and persistence are essential. Some cats require several weeks of tube feeding before their appetite will return or healing occurs. At least twice weekly, offer your cat a small amount of a favourite food so that you will know when its appetite is improving. The oesophagostomy tube will not hinder chewing or swallowing. After your cat has been eating well for 3-4 days, he should be returned to the hospital for tube removal. Removal of the tube is simple and does not require anaesthesia; however, you should not attempt to remove the tube on your own.
Feeding plan:
Your vet will advise you on how much to feed and how often. Usually we recommend to feed your cat 1/3rd of their requirement of Day one, 2/3rd of their requirement on Day 2 and the full amount on Day 3.
