A nurse once explained to me how to get around the sigmoid kink with a colon tube.
There is a portal between the rectum and the first part of the colon that you have to pass through.
The rectum is usually empty. The large intestine transports its contents towards the rectum with the help of its peristalsis. The above mentioned gate is closed until the contents of the large intestine reach it. Then the rectum is filled. This triggers the urge to poop due to its lower volume and stretchability.
With an enema, in which the liquid is entered into the rectum, there is an urge to empty even with small amounts. Only when a certain amount is exceeded does it pour through the portal into the large intestine.
Now two scenarios:
In the case of a blockage, the rectum may already have filled up and the contents cannot be released despite the pressure.
A longer colon tube could now be used. The anus is made easy to slide and the colon tube is carefully inserted through it. The nurse coats the entire length of the tube with Vaseline, and then also with a water-soluble lubricant. The reason she gave was that when the water flow started, the water-soluble rinsed off as it was inserted further, while the Vaseline continued to adhere.
When the colon tube comes to that portal and the sigmoid kink, she opens the flow and guides it through this bottleneck with twisting and slight back and forth movements. The advantage of a full rectum is that the portal is still open.
Once this has been passed, the tube easily slides in deeper without any problems. Of course, always pay attention to possible resistance. She uses tubes with a closed tip and two lateral eyes, and lengths up to 50 cm and a diameter of around 10 mm (CH 30).
In the second scenario, lubrication is the same as above. The colon tube is slowly twisted and inserted up to the kink. The patient makes himself felt when he/she feels the internal resistance. Then the tube is pulled back a little and the patient is made to push hard as if to empty his rectum. This opens up the passage from the rectum to the large intestine. At this moment you try to guide the tube through this passage by turning it. That should always work.
In both variants, the recipient assumes a kneeling/elbow position, with the torso lowered.
It always works for us.
But don't forget: Always act carefully.
A pierced intestinal wall is always a life-threatening situation!!!
immediate medical help is required. An operation is inevitable!!!
Better to cancel a project if there are and problems!!!
Safety saves lives!!!
