Let me try this again. Nissen Fundoplication is a procedure that creates a one-way valve in the esophagus, to allow food to pass into the stomach, but prevent stomach acids from going into the esophagus and thus prevent GERD.
However many pts. who have had this surgery, have complications, and some of them are bloating, continued reflux (d/t wrap being too loose), or vomiting. Therefore it maybe the reason the mother states that abdominal thrusts can't be done, as it would be not only possibility ineffective, but risky. As many of these pts., and prone to aspiration. Some pts. even develop swallowing problems after the procedure is done, and is the reason I asked did the child have a GT.
Even though many pt. get them remioved a few months after the procedure, some don't d/t the problems with swallowing. Heck some folks even have to have the procedure done again, or some docs only do a partial warp. There are different beliefs and studies about this procedure, and some docs advise against having it done. For some it brings more problems then relief!
I always thought that the air from the abd, and the abd muscles were part of the process that helped you to cough. That force of the upward thrust also pushed air from the abd, creating the pressure that helps force out the obstruction. I maybe wrong, but that was my thinking.
The Heimlich is done at the top of the abd, where the warp has been done, another risk in my mind. Great question! I have been working at a GI clinic, so I find this very interesting!
