What is a diaper rash and is it serious?

Written by Joanna E. Betancourt MD FAAP

A diaper rash is any rash that develops inside the diaper area.

In mild cases, the skin might be red. In more severe cases, there may be painful open sores.

It is usually seen around the groin and inside the folds of the upper thighs and buttocks. Miles cases clear up within 3 to 4 days with treatment.

What causes diaper rash?

Over the years diaper rash has been blamed on many causes, such as teething, diet, and ammonia in the urine. However, we now believe it is caused by any of the following:

  • Too much moisture
  • Chafing or rubbing
  • When urine, stools, or both touch the skin for long period of time
  • Yeast infections
  • Bacterial infection
  • Allergic reaction to diaper material

When skin stays wet for too long, it starts to break down.

When wet skin is rubbed, it also damages more easily. Moisture from the soiled diaper can harm you baby’s skin and make it more prone to chafing. When this happens, a diaper rash may develop.

More than half of babies between 4 and 15 months of age develop diaper rash at least once in a 2-month period.

Diaper rash occurs more often when:

  • Babies get older-mostly between 8 to 10 months of age.
  • Babies are not kept clean and dry.
  • Babies have frequent stools, especially when the stool stay in their diaper overnight.
  • Babies have diarrhea
  • Babies begin to eat solid foods
  • Babies are taking antibiotics or in nursing babies whose mothers are taking antibiotics.

When to call the pediatrician?

Sometimes a diaper rashes need medical attention. Talk with your pediatrician if:

  • The rash does not look like it’s going away or gets worse 2 to 3 days after treatment.
  • The rash includes blisters or pus-filled sores.
  • Your baby is taking antibiotic and has a bright red rash with red spots at its edges. This might be a yeast infection.
  • Your baby has a fever along with a rash.
  • The rash is very painful. Your baby might have a skin condition called cellulitis.
  • What can I do if my baby gets diaper rash?

If your baby has a diaper rash (and to prevent future diaper rashes)

  1. It’s important to keep the area as clean and dry as possible. Change wet or soiled diaper right away. This helps cut down how much moisture is on the skin.
  2. Gently clean the diaper with water and a soft washcloth. Disposable diaper wipes may also be used. Avoid wipes that contain alcohol and fragrance.
  3. Use soap and water only if the stool does not come off easily. If the rash is severe, use a squirt bottle of water so you can clean and rinse without rubbing.
  4. Pat dry; do not rub. Allow the area to air-dry fully.
  5. Apply a thick layer of protective ointment or cream (such as on that contains zinc a oxide or petroleum jelly). These ointments are usually are usually thick and pasty and do not have to be completely removed at the next diaper change.
  6. Remember, heavy scrubbing or burring will only damage the skin more.
  7. Do not put the diaper on too tight, especially overnight. Keep the diaper loose so that the wet and soiled part does not rub against the skin as much.
  8. Use cream with steroids only if your pediatrician recommends them. They are rarely needed and may be harmful.
  9. Check with your pediatrician if the rash a) has blisters or pus-filled sores; does not go away within 2 to 3 days; Gets worse.

Many parents ask me if a cloth diaper is better than disposable diapers. Research suggests that diaper rashes are less common with the use of disposable diapers.

However, what is more important than the type of diaper is how often it is changed. Whether you use cloth diapers, disposables, or both, always change diapers as needed to keep your baby clean, dry, and healthy.

Hopefully, this little bit of background on diaper rashes give you some good insight about this condition that many babies have.

In the hospital with Julia

By Suzanne Berman, MD

Edwin Leap, MD, an emergency room physician, makes a touching plea to those of us in rural medicine: don’t abandon your inpatient practice and night call responsibilities.

He articulately describes white coat flight – the trend away from inpatient and ER call as many primary care physicians, and even some specialists, drop their hospital privileges in search of fewer hours, better patients, and better pay.   But he doesn’t address my major ongoing apprehension about inpatient care: frustration with the hospital milieu.

I like working at my office.  I can always park where I want to.  It’s laid out how I like, with all my stuff clean, functional, and close at hand.  And if something breaks, or someone builds a better ZXK Analyzer 2000, I can buy another one if I want.  But the main reason I like working at my office is: I have a great staff team.  Our nurses are cheerful, helpful, compassionate, and solid.  I know this, because I’ve worked with some of them for nearly ten years.   They know how I communicate, what worries me, what I do well, and what I need help with and when.   Similarly, they’re great at serving our patients without constant micromanaging, because they ask for help when it’s not clear what to do.  We’ve worked together so long, day in and day out, in sickness and in health, that we truly work well as a team.

Let’s contrast this empowered team with the inpatient experience of, oh, say, the same pediatrician at a smallish community hospital.   Because we’re physically removed from what’s happening with our patient 23 hours of the day, we have a lot of catching up to do in the remaining hour at the hospital.   And rather than an “hour of power,” it’s often marked with frustration:

Me: “Wow, this output log said Johnny hasn’t peed since yesterday afternoon.  Has he really not urinated in over 16 hours?”

Nurse: “Ummm… hmm, I don’t know.  Night shift didn’t tell me anything about his urine.”

Me: “That may be, but if he hasn’t peed in 12 hours, we might have a problem.”

Nurse: “Well, maybe he’s peed.  His mom has been changing his diapers.”

Me: “Well, if she’s changing diapers, then he’s peed.  So why didn’t night shift record his urine output like we asked?”

Nurse: “I don’t know.  You’d have to ask night shift.”

Me: “Well, night shift isn’t here.”

Nurse: “I’ll ask if mom can at least remember how many diapers she’s changed.” [leaves, comes back] “Oops, mom went home to get a shower.  Dad is here now.  He doesn’t know anything about diapers.  He hasn’t changed any in the past 5 minutes.”

Me:  “OK, well, please page the nurse supervisor to get a hold of night shift.  Because I’m really worried about this baby’s kidneys now.”

[ten minutes pass]

Nurse Supervisor arrives.

Nurse Supervisor: [after the above is relayed]  “Oh, OK, I’ll find out.”

[twenty minutes pass. My hour is up.  I need to be back at my office.]

Nurse Supervisor: “OK.  I got a hold of night shift.   She knows the baby peed but doesn’t remember how much.”

Me: “But why didn’t she write it down in the log?”

Nurse Supervisor: [shrugs] “Maybe it just didn’t seem that important.  But we can discuss it next month at our inservice.”

Nurse:  “How can you measure how much a baby pees, anyway?  It’s not like the baby can pee in a urinal.”

Nurse Supervisor: “I hope you don’t expect us to straight cath babies!”

Me: [surprised] “You do diaper weights.  Weigh the diaper dry, then put it on the baby.  When it’s wet, weigh it again.  The difference is pee.”

Nurse Supervisor: [frowning, peering at chart] “Doctor, you actually didn’t write an order for diaper weights.  Just urine output.”

Nurse: [thinking through the previous instruction]  “….But that would give you a weight in grams.  Do you want us to record urine in grams?”

Me: “No!  One gram is one milliliter of urine.”

Nurse Supervisor: “Also, the computer system doesn’t allow us to put in diaper weights.”

Nurse: “Oh, our scale is broken. We’d have to get a new one.”

Nurse Supervisor: [making note] “I can put in a Capital Expense Request Form.  However, I heard they’re not approving new expenses until the 3rd quarter.”

Me: “I. Just. Need. To. Know.  How. Much. This. Baby. Has. Peed.”

Nurse #2: [walking by] “Oh, I bet I know why that baby hasn’t peed.  Night shift told me they turned the IV fluids down because the rate seemed like too much for the baby, who was peeing too much.”

All: [????]

The hospital setting lacks the efficiency, communication, chain of command, and ready materials that I’ve come to expect in my office.

Julia Child could prepare a souffle anywhere, certainly, but she might find it difficult in my kitchen, which contains only one old wire whisk, spotty lighting, and an oven with an irregular temperature control.   If compelled to do so, she’d no doubt be asked by foodies why this souffle wasn’t up to her usual standards.  “Oh, you see,” she’d say cheerfully in her New England warble, “we’ve been camping in the country!

But unlike Julia, I’m held to a high standard of care whether I’m at my office or some other place.  It’s fundamentally easier to deliver good care when I’m in a familiar environment, surrounded by people and equipment I trust, than when my critical information is delivered (or not) by people unfamiliar to me (who was the mysterious nurse called “Night Shift,” anyway?). White coat flight isn’t an isolated phenomenon.  Many hospitals struggle with “pink scrub flight,” or the mass exodus of well-trained nurses from front-line care to higher-paying administrative jobs with better hours and less stress.   The crusty nursery nurse who’s been there since I was a nursery patient, whom I know and trust to spot a sick baby at 100 paces, has been replaced by a rotation of a half-dozen part-time nurses whose training and experience are primarily in adult medicine, and whose names I’m still struggling to remember.  If I feel a nurse made an inappropriate or unsafe call, I can report it, but I’m not part of her training or mentoring process; that’s “an internal hospital matter.”

If Julia knows she’s going to be working in a less-than-well-equipped kitchen, she’ll be sure to bring her own $59 zester.  But hospital work requires, with few exceptions, use of hospital staff and hospital equipment, for legal reasons.  And on a witness stand, when asked to explain a child’s bad outcome,  I can’t wittily demur about the less-than-optimal hospital setting; I’ll have to say that I did my best given the shortcomings of our local community hospital, a damning statement in the eyes of trial lawyers.

Dr. Leap is an experienced emergency room physician.  I would imagine that his hospital emergency departments are well-managed such that he has a similar experience to me working in my office.   After signing in, he’ll work an eight-to-twelve hour shift with the same nurses, therapists, and techs he’s worked closely with for the past three to fifteen years.  New faces get assimilated into an experienced team quickly, because he’s working side-by-side with them, watching their performance. He knows Lab Tech David is the best “sticker” on old-lady-veins this side of Interstate 55, so that’s who he taps to draw the blood on elderly Mrs. Jones.   Registered Nurse Mendoza is compassionate, gentle, and bilingual, so she’ll work with the Latina woman coming in for a sexual assault evaluation.    Registered Nurse Miller is new and not very experienced with chest pain patients, so letting her monitor heart rhythms isn’t a good thing for her to solo yet.   However, he’ll have an opportunity to mentor her today as they work closely together treating Mr. Aziz, who’s come in with chest pain.   Dr. Leap sees quickly what’s going well and what’s not – because he’s on site with his team, forming rapid assessments of the team’s skills and performance.  He can train or mentor new or inexperienced staff in the hands-on way most of us learn best.  Most importantly, he can intervene if things aren’t going well for his crew.

Money and hours are certainly paramount considerations in the decision of physicians to pursue or abandon inpatient responsibilities.  However, for the pediatrician who wants to treat her patients in the local hospital, we need to make the rest of the hospital as responsive to community physician leadership and ideas as Dr. Leap finds his emergency department.
