Diane Newman: Welcome. I’m Diane Newman. I’m an grownup nurse practitioner, adjunct professor of urology and surgical procedure, and a analysis investigator senior on the Perelman School of Medicine on the University of Pennsylvania in Philadelphia. This presentation, I wish to current to you coding expertise for hydrophilic catheters, in these catheters we use intermittently for intermittent catheterization. This is only a very fast timeline on the place we have gone with catheter expertise.

When you have a look at this, it is astounding to know that we have actually developed in what we now use, and for intermittent catheterization, what we’re educating our sufferers. We’ve actually moved away from pink rubber catheters. There’s been such a priority about latex now, latex acquired allergy symptoms, particularly within the healthcare setting, amongst nurses, even, imaginable that we actually do not wish to use a pink rubber catheter anymore. That’s now actually sort of been a pair hundred years outdated now. That’s one thing that is actually outdated.

We’ve moved now to far more hydrophilic coated catheters, and catheters that we’re discovering are a lot better for the affected person, and really a lot better for his or her urethra, so crucial. It actually enhances that have for that particular person performing in catheterization. Material has been round, and this slide simply provides you an concept of the several types of materials that we have seen in catheters used intermittently. The rubber latex was probably the most versatile. Of course, latex allergy is worried.

PVC, that is been round a very long time. Basically, that is a really cheap kind of catheter, tends to be stiffer. PEBA is a PVC free plastic kind of fabric, sturdy and versatile. Then now we have silicone catheters, which now we have discovered when used for intermittent catheterizations is they’ll actually perhaps be too versatile, they usually’re not simple to cross. Then now we have what now we have used largely within the hydrophilic catheters that we’re utilizing, PVP, and that is actually the premise of most catheters that we use for hydrophilic.

You have to comprehend, although, with these is now we have the fabric is that for the hydrophilic layer is adhered to the floor of that catheter. Where have we gone with design adjustments with expertise development on this space? Really, what the main focus has been on polymer properties, latex largely has been changed by silicone, polyvinyl, PVC, or natural PEBA. There’s benefits when manufacturing these merchandise: lowered prices, in fact, after which in fact, the priority has at all times been each time we have seen design adjustments, is there a priority with an allergic response from the affected person?

The hydrophilic polymer coating, as I stated, permits that catheter simply cross by way of, as a result of it binds a considerable amount of water. It produces a really slick, hydrophilic, hydrated layer on the catheter floor. It reduces the friction between the catheter and the urethral tissue as you cross it, particularly in a male urethra, which may be very lengthy in size. There’s much less pressure that it’s worthwhile to cross that catheter and insert it into the urethra. It actually, the info is displaying it stronger and stronger so far as the truth that it decreases trauma throughout catheterization, it is extra snug, and it improves ease of use.

The drawback is, there’s several types of methods you placed on that coating to make that floor hydrophilic. That could be a drawback for sure people who perhaps have issues with dexterity, so far as manipulating the packaging, and all the fabric that it’s worthwhile to coat that catheter. There could be issues with hydrophilic catheters. They could be painful as a result of they dry out. There could be friction sticking when that catheter, in time, it begins to dry out inflicting hematuria trauma, after which it could possibly result in tough catheterizations. That drawback is, after which you’ve got sufferers forcing that catheter by way of the urethra.

Again, it could possibly trigger strictures, and naturally it could possibly trigger a catheter-associated urinary tract an infection, as a result of the urethra is traumatized, bleeding, micro organism could also be launched into the system. Now, there was some proof within the literature about hydrophilic catheters. There’s truly been fairly an enormous few publications. I do have a reference checklist on the finish of this lecture which you can lookup this data by yourself if you’re so inclined.

Basically, the info and the scoping evaluate, which is printed this yr, so it is very current, in neurogenic and non-neurogenic sufferers who had urinary retention, they’d higher outcomes with hydrophilic coating. What have been the higher outcomes? Satisfaction, choice, much less adversarial occasions, which I simply talked about that may happen. UTIs, high quality of life was higher, price effectiveness, and fewer ache and discomfort. This slide is simply displaying you that every one in all, they’re optimistic, professional. That’s HCIC, hydrophilic coated intermittent catheters. They actually scoped out many, many various publications.

They’re displaying that impression on UTIs, very optimistic so far as lowering UTIs. Again, that is one other one. You see that every one on the backside, decreased ache and discomfort. We’ve recognized this fairly a nicely. Actually, the EAUN pointers in 2013 concluded that hydrophilic catheters cut back ache, and that the majority sufferers want them for consolation. I feel that is one thing that now we have to recollect. This is a good research, scoping evaluate, as a result of they checked out spinal wire harm, they checked out spina bifida and masks EPH. They checked out a lot of sufferers, which each women and men, displaying that, yeah, it is simply extra snug for the affected person to make use of a hydrophilic.

There’s no query that this technological development has actually been optimistic. We notice that. We do have some knowledge. We do know sufferers like these, and we do know that that hydrophilic catheter actually provides that easy, wettest floor as you cross that catheter by way of the urethra. Thus, hopefully decrease friction, decrease pressure, much less microtrauma to that catheter. Okay, in order that’s actually vital.

Let’s discuss a little bit bit about this, so far as these catheters. They do dry out. It’s a slippery kind of stickiness that may happen after they dry out. If we return to the Mandy Fader article in 2002 that she requested about this. Her goal was to know if there was sticking. When she says adherence, she means adherence of that sticky a part of the hydrophilic coating throughout withdrawal. It relies upon, in fact, on timing. You put it in, and as you withdraw, is it drying out and sticking to the urethra? She would wish to find out about smoothness of catheter elimination.

She checked out 61 males across the imply age of 54, and she or he in contrast 4 completely different hydrophilic catheters again then in 2002. I’ve to emphasize to you, expertise has developed since then. We’re at all times seeing new designs and new forms of coating. She checked out catheter consolation on insertion, elimination, consolation on the bladder and the penis in these males. She additionally checked out smoothness of that elimination, after which whether or not it was sticking. I feel these outcomes are considerably shocking. We could discover these outcomes shocking, however sticky occurred with elimination on all 4 of those catheters that she examined again then.

This is sort of what the themes, the sufferers have been saying. Oh, okay in the event you like being turned inside out. One-fourth sticks inside like adhering glue, ugh. Stuck badly, fairly painful to take away, dried out very quick, and gripped on tight to the penis wall. Again, small research, 61 males. The level is that there was some sticking occurring there. You see this down right here on that one query when she requested about sticking on elimination, a little bit or quite a bit, and people aren’t insignificant numbers.

These are the 4 several types of catheters that she examined. Again, this expertise most likely is outdated, it is developed since then, but it surely’s one thing that was beginning to be mentioned on this subject. What you see from that’s that the findings right here indicated that there have been variations. This is vital. Not all hydrophilic coated catheters are the identical. We do not know the way a lot actually that is occurring, however we do have some extra knowledge so far as what occurs with eradicating that catheter.

Actually, in 2016, there was truly a validated questionnaire that got here out known as Intermittent Catheterization Difficulty Questionnaire. I’ve used this in analysis, they usually truly put a query, have a look at that query quantity 11: I’ve a blocking sensation throughout catheter withdrawal. They have been requested in regards to the frequency of that occurring and the depth. You see that evolution from 2002 to 2016 to truly see if we may doc this in some analysis that we’re doing.

Actually, in a research that I’ve performed, which was supported by Wellspect, on 200 sufferers performing catheterization, largely males once more, they usually have been acting at UC for a protracted, 90% for one yr, and largely spinal wire neurogenic kind inhabitants right here. We did ask this questionnaire and we did publish this knowledge. Now, that query on there, “I have a blocking sensation during catheter remove,” sure, some people did have that. We’re beginning to see increasingly, so far as is there an issue with eradicating these catheters, so far as perhaps probably sticking to the urethra?

It’s vital to grasp that we have had catheters on a very long time, okay? Designs have actually developed, expertise has actually expanded, and now we have higher and higher catheters to show our sufferers with. We have to comprehend that hydrophilic has a variety of optimistic, so far as them being utilized to catheters that we use intermittently, however they’ll dry out. What we have to perceive extra is what’s occurring there, and might that drying out trigger some trauma to that urethra?

What I wish to direct you to is partly two, I wish to discuss to you in regards to the latest expertise that now we have. It’s known as Field Clean expertise, whereas against adhering that hydrophilic coating, the hydrophilic parts are embedded into the floor of the catheter. I hope you hear onto half two.
