This method is suitable for large doses of liquid drugs. This method is simple, safe and reliable, and does not waste drugs.
When applying gastric tube administration, a gold or hard wood spindle-shaped mouth opener with a handle should be prepared first, the surface should be smooth, the middle of the mouth opener should have a small hole inserted into the stomach tube.
Then prepare a drug administration tube or puppies with a diameter of o.5 ~ o.6 cm, and for large dogs with a diameter of 1-1.5 cm rubber tube or plastic tube. You can also use a 14 catheter instead).
When administering the medicine, the large dog should be in a seated position, and the young dog can raise the forequarters into an upright position.
The assistant put the spindle shaped orifice into the entrance, let the dog bite it tightly, and fixed the orifice at the corner of the mouth with a rope.
The doser held the stomach tube coated with lubricant, inserted it into the small hole of the orifice, pushed it slowly towards the pharx at the back of the tongue, and pushed the stomach tube into the esophagus with the swallowing action of the dog.
After insertion to a certain depth (measured with a gastric tube first, the insertion depth is from the end of the dog’s nose to the eighth rib), put the end of the gastric tube into a cup of water.
If bubbles emerge from the end of the gastric tube, it indicates that the gastric tube is inserted into the trachea, and it should be pulled out and inserted immediately; If there is no bubble, it indicates that the stomach has been inserted into the stomach.
At this time, the stomach tube should continue to push a part of the deep, and then connect the syringe without pushing the core from the end, and the drug liquid will slowly enter the stomach through the syringe and the stomach tube.
After the infusion of the liquid medicine, push the core of the syringe to push the remaining liquid medicine into the stomach, then pinch the mouth of the gastric tube, and slowly pull out, so as to prevent the liquid medicine remaining in the gastric tube from straying into the trachea.
The used gastric tube should be washed and then soaked with 0.1% negeramine solution for disinfection.
