Epidurals,
laughing gas help manage labor pain

Like maternity fashions, women’s preferred methods for
labor pain relief have changed with the times.
When loose shifts with demure Peter Pan collars were
popular in the 1950s, “twilight sleep,” induced with
a potent combination of morphine and scopolamine, was
the method of choice. As hemlines rose in the 1960s,
so did interest in drug-free “natural” childbirth.
Today, when stylish pregnant women are baring their
bellies in bikinis, the majority are asking for epidurals.
In this technique, an anesthesiologist injects medication
through a catheter inserted into the lower part of the
woman’s spine, blocking nerves leading to the uterus.
Anesthesiologists as well as natural childbirth advocates
say they hope that the one-size-fits-all approach to
managing labor pain remains forever outmoded. They note
that women’s satisfaction with their childbirth experience
rests not on how little pain they felt but on whether
their wishes about how to deal with it were respected.
“Pain
in any other circumstance indicates something bad,”
says University of Toronto nursing professor Ellen Hodnett.
“Pain
in childbirth is a whole different thing,” Hodnett says.
“Not that it can’t be terrible, and there aren’t ways
to relieve it when it’s bad.” She was one of the contributors
to a supplement examining labor pain published by the
“American Journal of Obstetrics and Gynecology” in May.
Maureen Corry, executive director of the Maternity Center
Association, a New York non-profit group that commissioned
the articles in the supplement, says American women
don’t have as many options as those in countries where
midwives attend most births.
“I
really don’t believe women have the full story,” Corry
says. “I think they don’t have access to the full array
of safe and effective methods. We need to know what’s
going on in hospitals.”
To help answer that question, Corry’s group recently
commissioned “Listening to Mothers,” a nationwide survey
of women’s childbirth experiences. The results are to
be released in late October.
For now, the main source of information about childbirth
pain management in the USA is the Society for Obstetric
Anesthesia and Perinatology, which surveys hospitals
periodically. The group just mailed out its fourth survey,
says president Joy Hawkins, director of obstetric anesthesia
at the University of Colorado Health Sciences Center
in Denver.
Increasing epidurals
When Manhattan psychotherapist Ellen Daniels delivered
her daughter in 1981, fewer than a quarter of women
who gave birth at large hospitals got epidurals.
“Those
were the days of gonzo girls,” Daniels says. “We were
woman warriors.” Their childbirth mantra, she says:
Don’t let anyone near you with medication.
By the time she delivered her son three years later,
Daniels says, her attitude had changed. Her labor was
not progressing, and both she and her doctor wanted
to avoid a Caesarean section. Exhausted and in pain,
Daniels says, she eagerly welcomed an epidural. “I do
not see that there is any glory in suffering through
pain that can be combated. It makes no sense.”
Today, apparently, a majority of women would agree with
her. At least half of all women who give birth in the
USA get an epidural. Women who give birth at hospitals
that deliver more than 1,500 babies a year are more
likely to get an epidural than women at smaller hospitals.
The obstetric anesthesia society’s last survey, conducted
in 1997, found that the proportion of women who received
epidurals for labor pain at the largest hospitals had
risen to more than 60 percent, compared with only 22
percent in 1981.
On the other hand, some hospitals that deliver fewer
than 500 babies a year don’t even offer epidurals because
they lack anesthesiologists trained to administer them.
Instead, those institutions use intravenous narcotics,
which can cross the placenta to the baby. In the mother,
narcotics can cause nausea, vomiting and sedation. In
the newborn, narcotics have been linked to such problems
as decreased alertness at birth.
Even among large hospitals, the epidural rate varies
widely, Hawkins says. In New York City, for example,
“the expectation there is you come in and have your
epidural and you have painless childbirth,” she says.
So the rate in New York hospitals is as high as 90 percent.
“I’m
close to Boulder (Colo.), the ‘au naturel’ sort of place,”
Hawkins says. “The expectations are different.” In Boulder,
she says, the epidural rate is more like 20 percent.
And that’s fine, too, Hawkins says. “Epidurals shouldn’t
be looked at as necessarily the first-line choice,”
she says.
Other options
Proponents of non-drug methods of pain relief, such
as baths or massage, would agree. They cite research
suggesting that epidurals increase the likelihood that
doctors will need to use forceps, a vacuum device or
even a Caesarean section to deliver the baby because
the mother is unable to push hard enough. And, they
note, some studies link epidurals to fevers in mothers,
leading doctors to treat their newborns with antibiotics
for suspected infections.
David Birnbach, chief of women’s anesthesia at the University
of Miami, questions whether such problems are caused
by epidurals or simply occur more often in women who
need one. Birnbach calls epidurals “the gold standard”
of labor pain relief. “You can participate in the experience,
you can push the baby out, and it takes the pain away.”
At least one paper in the “American Journal of Obstetrics
and Gynecology” supplement concluded that newer methods,
such as “walking” epidurals, don’t necessarily improve
women’s childbirth experience.
Birnbach says the lower doses of painkillers used in
walking epidurals bring almost immediate relief - compared
with 15 minutes for conventional epidurals - without
causing numbness in the legs. “When I trained, nobody
could get out of bed,” Birnbach says. “Those days are
gone.”
True, he says, not all women who get a walking epidural
actually walk. At his hospital, Birnbach says, about
a third do. Another third don’t want to, while the remainder
can’t because they are hooked up to monitors or other
devices that limit movement.
In a report published last month, the American College
of Obstetricians and Gynecologists concludes that even
women in early labor should be able to get an epidural
if they want one. But “I always say try our things first,”
says Penny Simkin, a Seattle doula, or labor support
provider, who wrote about non-drug alternatives in the
journal supplement on labor pain.
Simkin recommends touch and massage, movement and position
changes. For back pain, she says, injecting sterile
water in the back can provide immediate relief, possibly
by stimulating the production of endorphins. When labor
has progressed, baths can be soothing.
Somewhere between non-drug approaches and epidurals
is nitrous oxide, or “laughing gas,” widely used by
European women in childbirth. Anesthesiologist Mark
Rosen, of the University of California-San Francisco,
is one of only a handful of U.S. doctors who offers
it.
Says Rosen, who estimates that fewer than 10 percent
of his patients use nitrous oxide to take the edge off
childbirth pain: “It’s not amazingly effective, but
it’s a choice.”
