They are all silicone which is comfortable for the patient and much more secure than other bladder type catheters. They are anchored internally by a balloon and externallyby a skin disc.
The tubes are normally used as a replacement device which does not require endoscopy and can be fitted on an outpatient basis or in the community.
A separate clamp is available for all sizes of gastrostomy tubes. The clamp is useful for closing off the tube during feeding connections.
An additional keyhole dressing is available for use with sore sites below the skin disc placement.
Gastrostomy Tubes placement instructions in hospital or community.
- The site should be cleaned with betadine or equivalent then the tube tip is lubricated with a water based lubricant.
- The skin disc should be moved upwards to the wider feeding adaptor.
- The tip can then be gently inserted through the tract up to the top 6cm mark into the stomach. An introducer in not normally necessary.
- The balloon is then filled with saline or water to anchor the tube internally and the skin disc is brought down to anchor the tube externally.
- The maximum balloon volume for 12FR, 14FR and 16FR tubes is 5mls. The maximum volume for all other sizes is 20mls. Never inflate the balloon with air.
- It is not normally necessary to secure the skin disc to the skin or the tube. The skin disc should not be pulled too tightly against the skin. There should be a small amount of in and out play.
- If insertion of the tube is difficult, a lateral abdominal X-ray should be performed to exclude positioning in the peritoneal cavity.
