Timestops (3)

Anatomical Problems and Initial Management

Aspiration Detection and Diagnostic Methods

Saliva Aspiration and Tracheotomy Considerations

Topic Overview

A didactic discussion on aspiration in pediatric patients, focusing on tracheoesophageal fistulas and related conditions. The speaker outlines a framework distinguishing functional/neurological causes (cerebral palsy, CHARGE syndrome) from anatomical causes (TEF, laryngeal cleft, pharyngeal scarring, esophageal stenosis). Management strategies are presented for aspiration of food/drink (NG/G-tube), saliva (Robinul, Botox, drool procedure, tracheostomy, laryngotracheal separation), and reflux (fundoplication, GJ tube). Diagnostic approaches are discussed by a pulmonologist and gastroenterologist, emphasizing dye testing in tracheostomy patients, video/endoscopic swallow studies, and the limitations of lipid-laden macrophages and impedance testing as aspiration markers.

Key Takeaways

Most aspiration in children is functional/neurological (CP, CHARGE), not anatomical (TEF, cleft). (0:10)
Laryngotracheal separation is the only guaranteed aspiration cure but eliminates vocalization. (1:53)
Dye test via trach (green preferred) is simplest aspiration test; repeatable at home, convinces parents. (2:55)
Lipid-laden macrophages are non-specific; convincing only in high numbers with right clinical context. (3:35)
Impedance testing detects reflux but does not diagnose aspiration itself. (5:08)

Transcript

But we're gonna start off with tracheoesophageal fistulas, and the framework of how to think about children who aspirate. Most children who aspirate, have a functional or neurological problem. They've got cerebral palsy, they've got CH syndrome. Some children have an anatomical problem. And so the anatomical problems could be the obvious, the tracheoesophageal fistula or a laryngeal cleft. In some children, they've got a bad pharyngeal scar. In some children, you might have esophageal stenosis with backup and spillover. And so the next aspect to grasp is what can you aspirate. And so the obvious is food and drink. And what can you do about that? You could consider a nasogastric tube or a gastrostomy tube. The next group of children who aspirate their saliva. And again, there's a lot of different things that we can do to help manage those children. Something as simple as medication like Robinul. Generally, it doesn't work, but you can try it. Uh, we can Botox the major salivary glands, a temporary solution, but it's a good test run for how a child would cope with less saliva. We quite frequently do a drool procedure. We remove the submandibular glands and ligate the parotid ducts. If necessary, you can place a tracheotomy. It allows you to suction the airway clear of secretions. You could put BiPAP on a tracheostomy, so that any secretions are blown up and out of the mouth. And if you truly want to stop aspiration, there's only one guaranteed operation, which is a laryngotracheal separation. Which is not something that is commonly done because you lose your ability to vocalize. The other things that you can aspirate a reflux, gastroesophageal reflux, and again, a Nissan fundoplication or any sort of fundoplication may assist with that, or even a GJ tube. And very occasionally we'll see a child who aspirates their esophageal contents. Tight fundoplication, non-motile esophagus, you can get accumulation and spillover. And so testing, how can we test for the different sorts of aspiration? And so this is firstly a question to the panel. Uh, what are your preferences if you're trying to test for aspiration for, say, food and drink? I think we'll start off with the pulmonologist here, Bob. Well, obviously it depends on the, the child. Uh, if a child has a tracheostomy, the simplest test is to put some colored dye in his mouth and see if it comes out of his trach tube. That's something you can do at home in a normal setting and do repeatedly. It's also very helpful to convince skeptical parents that the child actually is aspirating because sometimes we have a lot of trouble with that. Uh, video swallow studies or endoscopic swallow studies can also be very useful. Uh, Endoscopically, one of the things that we look for is direct evidence of aspiration, and unfortunately there are no unequivocal markers of aspiration. We talk about lipid-laden macrophages, but they are not only non-specific, but the recovery of lipid-laden macrophages depends on what material was aspirated, how much lipid did it contain. The amount that was aspirated and more importantly, how long it's been since the aspiration event took place. If we see lots and lots of lipid laden macrophages in the right clinical setting, we say, yeah, this is convincing evidence that the patient is aspirating, but it's certainly not a black and white yes no answer. And if we move into saliva, Again, what are the things we can do if you've got a tracheotomy, you can again, as Bob said, do a dye test, a drop of green food dye on the tongue, and see if it comes out the trach tube. Uh, green is a great color because it's not natural, red, blue, other colors, you might confuse it with something that the body actually produces, but green's pretty characteristic. And if you don't have a tracheotomy, Again, you may have to look at whether a nuclear medicine scan is necessary, a drop of something radioactive on the tongue and see if it ends up in the lungs or the stomach. And of course, gastroesophageal reflux, and I think we'll pass that one on to Phil. There's a variety of interesting things there. Are you a believer in any of them, Phil? As a marker for aspiration, none of them are particularly good, um. Multi-channel intraluminal impedance testing is mostly replaced simple pH testing for the detection of reflux, um, but it doesn't add anything to the diagnosis of aspiration itself. It tells you whether something is being delivered from the stomach of the esophagus, but not what happens to it after that.
