Tales from the hospital newborn rounds… how to educate about breastfeeding?

IMG_3419Tales from the hospital newborn rounds… how to educate about breastfeeding?

I love breastfeeding questions.  I helped educate both medical students and new mothers this week about breastfeeding while on newborn hospital rounds.  Here are some of the questions (and answers!)…

What do you have to do to be successful at breastfeeding?  You need to be a woman with breasts (every mother is included in this), you have to want to breastfeed, and you have to try to breastfeed (every 3 hours) or more often, as baby wants.

How long to “try”?  Your milk should “come in” by day 3 to 5 postpartum.  By 2 weeks the baby and mother should know what to do.  There are some women who do not make milk either because of lack of production or altered breast anatomy (inverted nipples make latching difficult and previous breast surgery may also impact milk ducts).

What are the benefits to breastmilk?

  • Maternal benefits: decreased risk of breast and ovarian cancer, decreased type 2 diabetes, high blood pressure and cardiovascular disease, decreased postpartum depression
  • Infant benefits: decreased eczema and gastroenteritis, higher IQ (no kidding!) later in life, decreased risk of childhood leukemia, decreased risk of obesity both as a child and as an adult, decreased SIDS, reduced risk of almost every kind of infection (intestinal, ear infection, lung infection, pneumonia) and less risk of asthma.

How long to breastfeed?  All major health organizations recommend exclusive breastfeeding for the first six months of life, then complimentary foods can be introduced with continued breastfeeding until 12 months of age.  But, I tell mothers, any amount of breastmilk is better than less.  So, if you can breastfeed for the first 6 weeks (before returning to school or work) that’s better than 5 weeks.  And, now, breast pumps are often free which helps mothers express their breastmilk when they are not with baby.  Start breastfeeding and see how it goes…

I hope this helps.IMG_3419

Tales from the hospital newborn rounds with medical students…What do we screen for?


Tales from the hospital newborn rounds with medical students… What do we screen for?

Oh, my life as a physician and medical educator.  I have a new crop of green third-year medical students.  They have just spent two years studying books.  Now, they get to see patients and do what most of them have been dreaming about for years.

I am the “newborn attending physician” this week and am tasked to see new babies at the local hospitals.  The medical students, most of whom are not parents themselves, are bright and eager to learn about babies.  One question that they brought up is…

Which newborn screenings are recommended and why?

  1. Congenital heart defects.  To screen for this we measure the oxygen saturation in the newborn’s blood with a probe (that looks like a light on a bandaid) at 24 hours of age.  If this is abnormal, an ultrasound of the heart (an echocardiogram) is done to see if there are structural cardiac problems.
  2. Genetic and metabolic disorders.  A heel-stick blood draw is done after 24 hours of age to test the newborn’s ability to break down milk proteins and other genetic abnormalities.  This is done by the State lab and Nevada asks for two “newborn screens”:  one done at 24 hours of age and one at 2 weeks of age.
  3. Hearing impairment.  This is done by screening for the auditory brainstem response wherein a hospital technician does a non-invasive test on a hopefully sleeping or calm infant.  (It is done this way as newborns will not raise their hand when a sound is heard.)  Sometimes, the initial screen is abnormal (most commonly due to fluid in the ears) and is repeated a few weeks later.  If still abnormal, then an audiologist is consulted.
  4. Hyperbilirubinemia (jaundice).  A transcutaneous bilirubin level is obtained by putting a non-invasive light on the newborn’s upper chest to read how much bilirubin is in the skin.  If this is elevated, then a venous sample is obtained.  If this is high, then the newborn is placed under blue lights called “bili lights.”  This is to help the bilirubin from crossing the blood-brain barrier and causing brain damage.

I hope this helps….newborn

Marijuana and adolescents…

Marijuana and adolescents…  I live in Nevada and it is now legal to use marijuana for both recreational and medical use.

How prevalent is marijuana use? 5.4% of 8th graders, 14% of 10th graders and 22% of 12th graders have used marijuana at least once in the past month.  Marijuana is second most-used substance after alcohol for adolescents.

Adults may view marijuana use as benign or not harmful, but there are major concerns about use in adolescents.  Regular or heavy or daily use of marijuana can lead to adverse medial, mental, psychosocial and cognitive outcomes.  Brain maturation is not complete until the mid-20s.  Negative outcomes can include

  • delayed reaction time,
  • impaired motor coordination,
  • higher rates of serious or fatal motor vehicle crashes,
  • poor work and school performance,
  • increased school dropout rates,
  • and anxiety.
  • Those with a predisposition to schizophrenia can have their first episode of hallucination associated with marijuana-use.

What is the risk of chronic marijuana use?  It increases the younger that marijuana is started.  Those adolescents who use marijuana daily, the risk of long-term use is 25-50%.  Whereas there is a 9% regular use in those who experiment with it.

There is a lack of regulation by the US Food and Drug Administration regarding marijuana…  so purity, THC (tetrahydrocannabinol) concentration and CBD (cannabidiol) concentrations are different with each batch.  Also, the method for which it is ingested changes its effect: eaten, drank, topical administration, vaped or smoked.  The concentration of THC (the psychoactive substance in marijuana plant) has increased greatly over the years: 4% in 1995 to 12% in 2014.

Talk with your children about the dangers of marijuana use.  Consider stopping yourself.   Ask your physician for help.

Should you as an ex-smoker have a CT scan to rule out lung cancer?

Should you as an ex-smoker have a CT scan to rule out lung cancer?  This is a great question.

A few years ago the National Lung Screening Trial found a reduction in disease-specific and all-cause mortality with lung cancer screening.  THEN the Canadian Task Force on Preventive Health Care AND the U.S Preventive Services Task Force voted in favor of a low-dose lung CT scan in those aged 55-80 who have a 30-pack/year smoking history (like one pack a day for 30 years) and currently smoke or have quit within the past 15 years.  So, we physicians, have been ordering low-dose lung CT scans on appropriate patients.

What were the results?  In a small group of Veterans Health Administration patients, it was found that 97.5% of patients who were told they had an abnormal lung CT DID NOT have lung cancer.

Where does this leave us?  The patient and physician should have a discussion about the risks of a false-positive result (a concerning lung CT with subsequent negative work up) and other harms such as radiation exposure, over-

Pregnant women, should you ask for skin staples or stitches with a C-section?

Pregnant women, should you ask for skin staples or stitches with a C-section?  A meta-analysis (combined multiple studies) with 2300 patients looked at complication rate or infection, separation, hematomas (blood collections under the skin surface) and cosmetic result.

All 10 studies included showed that the staples group had an increased risk of wound complications compared with the sutures group.  Otherwise, the cosmetic result between the two groups was comparable at 8 weeks postpartum, but at 12 months postpartum the suture group had a better looking scar per observer scores (and similar-resulting scar per the patient themselves).
