The
medical approach to pregnancy and birth has become so ingrained in our culture,
that we have forgotten the way of birth of our ancestors: a way that has ensured
our survival as a species for millennia. In the rush to supposedly protect
mothers and babies from misfortune and death, modern western obstetrics has
neglected to pay its dues to the Goddess, to Mother Nature, whose complex and
elegant systems of birth are interfered with on every level by this new
approach, even as we admit our inability to understand or control these
elemental forces.
Medical
interference in pregnancy, labour and birth is well documented, and the negative
sequelae are well researched. However, medical management of the third stage of
labour- the time between the baby’s birth, and the emergence of the placenta-,
to my mind, more insidious. At the time when Mother Nature prescribes awe and
ecstasy, we have injections, examinations, and clamping and pulling on the cord.
Instead of body heat and skin-to-skin contact, we have separation and wrapping.
Where time should stand still for those eternal moments of first contact, as
mother and baby fall deeply in love, we have haste to deliver the placenta and
clean up for the next ‘case’.
This
‘management ‘ of the third stage, which has been taken even further in the
last ten years, with the popularity of “active management of the third
stage” (see below), has its own risks for mother and baby. While much of the
activity is designed to reduce the risk of maternal bleeding, or postpartum
haemorrhage (PPH), which is most certainly a serious event, it seems that, as
with the active management of labour, the medical approach to labour and birth
actually leads to many of the problems that active management is designed to
address.
Active
management also creates specific and potentially life-threatening problems for
mother and baby. In particular, use of active management leads to a newborn baby
being deprived of up to half of his or her expected blood volume. This extra
blood, which is intended to perfuse the newly functioning lungs and other vital
organs, is discarded along with the placenta when active management is used,
with possible sequelae such as breathing difficulties and anaemia, especially in
vulnerable babies.
Drugs
used in active management have documented risks for the mother, including death,
and we do not know the long-term effects of these drugs, which are given at a
critical stage of brain development, for the baby.
Hormones in the third stage
As
a mammalian species- that is, we have mammary glands that produce milk for our
young- we share almost all features of labour and birth with our fellow mammals.
We have in common the complex orchestration of labour hormones, produced deep
within our “mammalian”, or middle brain, to aid us and ultimately ensure the
survival of our offspring.
We
are helped in birth by three major mammalian hormone systems, all of which play
important roles in the third stage as well. The hormone oxytocin causes the
uterine contractions that signal labour, as well as helping us to enact our
instinctive mothering behaviours. Endorphins, the body’s natural opiates,
produce an altered state of consciousness and aid us in transmuting pain: and
the fight or flight hormones adrenaline and noradrenaline (epinephrine and
norepinephrine- also known as catecholamines or CAs) give us the burst of energy
that we need to push our babies out in second stage.
During
the third stage of labour, strong uterine contractions continue at regular
intervals, under the continuing influence of oxytocin. The uterine muscle fibres
shorten, or retract, with each contraction, leading to a gradual decrease in the
size of the uterus, which helps to “shear” the placenta away from its
attachment site. Third stage is complete when the placenta is delivered.
For
the new mother, the third stage is a time of reaping the rewards of her labour.
Mother Nature provides peak levels of oxytocin, the hormone of love, and
endorphins, hormones of pleasure for both mother and baby. Skin to skin contact
and the baby’s first attempts to breast-feed further augment maternal oxytocin
levels, strengthening the uterine contractions that will help the placenta to
separate, and the uterus to contract down. In this way, oxytocin acts to prevent
haemorrhage, as well as to establish, in concert with the other hormones, the
close bond that will ensure a mother’s care and protection, and thus her
baby’s survival.
At
this time, the high adrenaline levels of second stage, which have kept mother
and baby wide-eyed and alert at first contact, will be falling, and a very warm
atmosphere is necessary to counteract the cold, shivering feelings that a woman
has as her adrenaline levels drop. If the environment is not well heated, and/or
the mother is worried or distracted, continuing high levels of adrenaline will
counteract oxytocin’s beneficial effects on her uterus, therefore, according
to Odent (1992), increasing the risk of haemorrhage.
For
the baby as well, the reduction in fight or flight hormones, which have also
peaked at birth, is critical. If, because of extended separation, these hormones
are not soothed by contact with the mother, the baby can go into psychological
shock, which, according to author Joseph Chilton Pearce, will prevent the
activation of specific brain functions that is nature’s blueprint for this
time. Pearce believes that the separation of mother and baby after birth is
“the most devastating event of life, which leaves us emotionally and
psychologically crippled” (Pearce 1992)
One
might wonder whether the modern epidemic of “stress” - the term was invented
by researchers in the early 20th century- and stress-related illness
in our culture is a further outcome of current third-stage practices. It is
scientifically plausible that our entire Hypothalamic-Pituitary-Adrenal (HPA)
axis, which mediates long-term stress responses and immune function, as well as
short-term fight-or-flight reaction, is permanently mis-set by the continuing
high stress hormone levels that ensue when newborn babies are routinely
separated from their mothers.
Michel
Odent, in his review of research on the “primal period” (the time between
conception and the first birthday), concludes that interference or dysfunction
at this time affects the development of our “capacity to love”, which is
particularly vulnerable around the time of birth, being connected hormonally to
the oxytocin system. (Odent, 1998) Research by Jacobsen (1990, 1997)) and Raine
(1994), among others, suggests that contemporary tragedies such as suicide, drug
addiction and violent criminality may be linked to problems in the perinatal
period such as exposure to drugs, birth complications and separation or
rejection from the mother.
A
crucial role for birth attendants in these times is to ensure that a woman’s
mammalian instincts are protected and valued during pregnancy, birth and
afterwards. Ensuring unhurried and uninterrupted contact between mother and baby
after birth, adjusting the temperature to accommodate a shivering mother, and to
allow skin-to-skin contact and breastfeeding, and not removing the baby for any
reason- these are practices that are sensible, intuitive and safe, and help to
synchronise our hormonal systems with our genetic blueprint, giving maximum
success and pleasure for both partners, in the critical function of
child-rearing.
The
baby, the cord, and active management
Adaptation
to life outside the womb is the major physiological task for the baby in third
stage. In utero, the wondrous placenta fulfils the functions of lungs, kidney,
gut and liver for our babies. Blood flow to these organs is minimal until the
baby takes a first breath, at which time huge changes begin in the organisation
of the circulatory system
Within
the baby’s body, blood becomes, over several minutes, diverted away from the
umbilical cord and placenta and, as the lungs fill with air, blood is sucked
into the pulmonary (lung) circulation. Mother Nature ensures a reservoir of
blood in the cord and placenta that provides the additional blood necessary for
these newly perfused pulmonary and organ systems.
The
transfer of this reservoir of blood from the placenta to the baby happens in a
step-wise progression, with blood entering the baby with each third-stage
contraction, and some blood returning to the placenta between contractions.
Crying slows the intake of blood, which is also controlled by constriction of
the vessels within the cord (Gunther 1957) – both of which imply that the baby
may be able to regulate the transfusion according to individual need.
Gravity
will affect the transfer of blood, with optimal transfer occurring when the baby
remains at or below the level of the uterus until the cessation of cord
pulsation signals that the transfer is complete. This process of
“physiological clamping” typically takes 3 minutes, but may be longer, or
can be complete in only one minute. (Linderkamp 1982)
This
elegant and time-tested system, which ensures that an optimum, but not a
standard, amount of blood is transferred, is rendered inoperable by the current
practice of early clamping of the cord- usually within 30 seconds of birth.
Early
clamping has been widely adopted in Western obstetrics as part of the package
known as active management of the third stage. This comprises the use of an
oxytocic agent- a drug that, like oxytocin, causes the uterus to contract
strongly- given usually by injection into the mothers thigh as the baby is born,
as well as early cord clamping, and ‘controlled cord traction’- that is,
pulling on the cord to deliver the placenta as quickly as possible.
Haste
becomes necessary, because the oxytocic injection will, within a few minutes,
cause very strong uterine contractions that can trap an undelivered placenta,
making an operation and ‘manual removal’ necessary. Furthermore, if the cord
is not clamped before the oxytocic effect commences, the baby is at risk of
having too much blood suddenly pumped from the placenta by the over-zealous
contractions.
While
the aim of active management is to reduce the risk of haemorrhage for the
mother, “its widespread acceptance was not preceded by studies evaluating the
effects of depriving neonates [newborn babies] of a significant volume of
blood” (Piscane 1996)
It
is estimated that early clamping deprives the baby of 54 to 160 ml of blood,
(Usher 1963) which represents up to half of a baby’s total blood volume at
birth. “Clamping the cord before the infant’s first breath results in blood
being sacrificed from other organs to establish pulmonary perfusion. [Blood
supply to the lungs]. Fatality may result if the child is already hypovolemic
[low in blood volume].” (Morley 1997)
Where
the baby is lifted above the uterus before clamping- for example during
caesarean surgery- blood will drain back to the placenta by gravity, making
these babies especially liable to receive less than their expected blood volume.
The consequence of this may be an increased risk of respiratory (breathing)
distress- several studies have shown this condition, which is common in
caesarean-born babies, to be eliminated when a full placental transfusion was
allowed. (Peltonen 1981, Landau 1953).
The
baby whose cord is clamped early also loses the iron contained within that
blood- early clamping has been linked with an extra risk of anaemia in infancy.
(Grajeda 1997, Michaelson 1995).
These
sequelae of early clamping were recognised as far back as 1801, when Erasmus
Darwin wrote
“Another
thing very injurious to the child is the tying and cutting of the navel string
too soon; which should always be left till the child has not only repeatedly
breathed but till all pulsation in the cord ceases. As otherwise the child is
much weaker than it ought to be, a part of the blood being left in the placenta
which ought to have been in the child” (Darwin 1801).
In
one study, premature babies experiencing delayed cord clamping-, the delay was
only 30 seconds- showed a reduced need for transfusion, less severe breathing
problems, better oxygen levels, and indications of probable improved long-term
outcomes, compared to those whose cords were clamped immediately. (Kinmond
1993).
Some
studies have shown an increased risk of polycythemia (more red blood cells in
the blood) and jaundice when the cord is clamped later. Polycythemia may be
beneficial, in that more red cells means more oxygen being delivered to the
tissues. The risk that polycythemia will cause the blood to become too thick
(hyperviscosity syndrome), which is often used as an argument against delayed
cord clamping, seems to be negligible in healthy babies. (Morley 1998)
Jaundice
is almost certain when a baby gets his or her full quota of blood, and is caused
by the breakdown of the normal excess of blood to produce bilirubin, the pigment
that causes the yellow appearance of a jaundiced baby. There is, however, no
evidence of adverse effects from this. (Morley 1998). One author has proposed
that jaundice, which is present in almost all human infants to some extent, and
which is often prolonged by breastfeeding, may actually be beneficial because of
the anti-oxidant properties of bilirubin. (Gartner 1998)
Early
cord clamping carries the further disadvantage of depriving the baby of the
oxygen-rich placental blood that Mother Nature provides to tide the baby over
until breathing is well established. In situations of extreme distress- for
example, if the baby takes several minutes to breathe-this reservoir of
oxygenated blood can be life saving, but, ironically, standard practice is to
cut the cord immediately if resuscitation is needed.
The
placental circulation acts, when the cord is intact, as a conduit for any drug
given to the mother, whether during pregnancy, labour or third stage. Garrison
(1999) reports that Narcan, which is sometimes needed by the baby to counteract
the sedating effect of pain-relieving drugs such as pethidine (Demerol), given
to the mother in labour, can be effectively administered via the mother’s
veins in third stage, waking up the newborn baby in a matter of seconds.
The
recent discovery of the amazing properties of cord blood, in particular the stem
cells contained within it, heightens, for me, the need to ensure that a newborn
baby gets its full quota. These cells are unique to this stage of development,
and will migrate to the baby’s bone morrow soon after birth, transforming
themselves into various types of blood-making cells,
Cord
blood harvesting, which is currently being promoted to fill Cord Blood Banks for
future treatment of children with leukaemia, involves immediate clamping, and up
to 100 ml of this extraordinary blood can be taken from the baby to whom it
belongs. Perhaps this is justifiable where active management is practiced, and
the blood would be otherwise discarded, but, unfortunately, cord blood donation
is incompatible with a physiological (natural) third stage.
Active
management and the mother
Active
management (oxytocic, early clamping and controlled cord traction) represents a
further development in third stage interference that began in the
mid-seventeenth century, when male attendants began confining women to bed, and
cord clamping was introduced to spare the bed linen.
Mauriceau
first recommended pulling on the cord in 1673, who feared that the uterus might
close before the placenta was spontaneously delivered (Inch 1984). In fact, the
recumbent (lying) postures, increasingly adopted under doctor’s care meant
that spontaneous delivery of the placenta was less likely: the upright postures
that women and midwives have traditionally used encourage the placenta to fall
out with the help of gravity.
The
first oxytocic to be used medically was ergot, derived from a fungal infection
of rye. Ergot was known to be used by 17th and 18th
century European midwives. Its use was limited, however, by its toxicity. It was
refined and revived as ergometrine in the 1930’s, and by the late 1940’s,
some doctors were using it as a preventatively, as well as therapeutically, for
post partum haemorrhage. (Inch 1984) Potential side effects from ergot
derivatives include a rise in blood pressure, nausea, vomiting, headache,
palpitations, cerebral haemorrhage, cardiac arrest, convulsion and even death.
Synthetic
oxytocin, which mimics the effects of natural oxytocin on the uterus, was first
marketed in the 1950’s, and has largely replaced ergometrine, although a
combination drug, called syntometrine, is still used, especially for severe
haemorrhage. Syntocinon causes an increase in the strength of contractions,
whereas ergometrine causes a large, ‘tonic’ contraction, which also
increases the chance of trapping the placenta. Ergometrine also interferes with
the process of placental separation, increasing the chance of partial
separation. (Sorbe 1978)
Recently
active management has been proclaimed “the routine management of choice for
women expecting a single baby by vaginal delivery in a maternity hospital” (Prendville
1999), mostly because of the results of the recent Hinchingbrooke trial,
comparing active versus “expectant” (physiological) management.
In
this trial (Rogers 1998), which involved only women at low risk of bleeding,
active management was associated with a post partum haemorrhage (blood loss
greater than 500ml) rate of 6.8%, compared with 16.5% for expectant (non-active)
management. Rates of severe PPH (loss > 1000ml) were low in both groups- 1.7%
active and 2.6% expectant.
The
authors note further that, from these figures ten women would need to receive
active management to prevent one PPH. They add,
“Some women … may rate a small personal risk of PPH of little
importance compared with intervention in an otherwise straightforward labour,
whereas others may wish to take all measures to reduce the risk of PPH.”
Reading
this paper, one must wonder how it is that almost 1 in 6 women bled after
“physiological” management, and whether one or more components of western
obstetric practices might not be actually increasing the rate of haemorrhage.
Botha
(1968) attended over 26 000 Bantu women over 10 years, and reports that “a
retained placenta was seldom seen…blood transfusion for postpartum haemorrhage
was never necessary.” Bantu women deliver both baby and placenta while
squatting, and the cord is not attended to until the placenta delivers itself by
gravity.
There
is some evidence that the practice of clamping the cord, which is not practiced
by indigenous cultures, contributes to both PPH and retained placenta by
trapping extra blood (around 100ml, as described above) within the placenta.
This increases placental bulk, which the uterus cannot contract efficiently
against, and which is more difficult to expel. (Walsh 1968)
Other
western practices that may contribute to PPH include the use of oxytocin for
induction and augmentation (speeding up labour) (Brinsden 1978, McKenzie 1979),
episiotomy or perineal trauma, forceps delivery, caesarean and previous
caesarean (because of placental problems- see Hemminki 1996).
Gilbert
(1987) notes that PPH rates in her UK hospital more than doubled from 5% in
1969-70 to 11% in 1983-5, and concludes, “The changes in labour ward practice
over the last 20 years have resulted in the re-emergence of PPH as a significant
problem.” In particular, she links an increased risk of bleeding with
induction using oxytocin, forceps delivery, long first and second stages (but
not prolonged pushing) and the use of epidurals, which increase the chance of
forceps and of a long second stage.
As
noted, western practices do not facilitate the production of a mother’s own
oxytocin, neither is attention paid to reducing adrenaline levels in the minutes
after birth, both of which are physiologically likely to improve uterine
contractions and therefore reduce haemorrhage.
Clamping
the cord, especially at an early stage, may also cause the extra blood trapped
within the placenta to be forced back through the placenta into the mothers
blood supply with the third stage contractions. (Doolittle 1966, Lapido 1971)
This “feto-maternal transfusion” increases the chance of future blood group
incompatibility problems, which occur when the current baby’s blood enters the
mother’s blood stream, causing an immune reaction which can be reactivated and
destroy the baby’s blood cells in a subsequent pregnancy, causing anaemia or
even death.
The
use of oxytocin, which strengthens contractions, either during labour, or in
third stage, has also been linked to an increased risk of feto-maternal
haemorrhage and blood group incompatibility problems. (Beer 1969, Weinstein
1971)
The
World Health Organisation, in its 1996 publication Care
in Normal Birth: a practical guide, argue that “In a healthy population
(as is the case in most developed countries), postpartum blood loss up to 1000
ml may be considered as physiological and does not necessitate treatment other
than oxytocics…” In relation to routine oxytocics and controlled cord
traction, WHO cautions that “Recommendation of such a policy would imply that
the benefits of such management would offset and even exceed the risks,
including potentially rare but serious risks that might become manifest in the
future.”.
Choosing
a natural third stage
Choosing
to forego preventative oxytocics, to clamp late (if at all), and to deliver the
placenta by our own effort all require forethought, commitment, and that we
choose birth attendants that are comfortable and experienced with these choices.
A
natural third stage is more than this; however-we must ensure respect for the
emotional and hormonal processes of both mother and baby, remembering how unique
this time is. Michel Odent stresses the importance of not interrupting, even
with words, and believes that ideally the new mother feels unobserved and
uninhibited in the first encounter with her baby. (Odent 1992) This level of non-interference is uncommon, even in home and
birth centre settings.
Lotus
birth, the subject of this book, gives us a further chance to “slow the fire
drill” after birth, as midwife Gloria Lemay puts it, and allows our babies the
full metaphysical, as well as physical, benefit of prolonged contact with the
placenta. Lotus birth, like a good midwife, also secludes mother and baby in the
early hours and days, ensuring rest and keeping visitors to a minimum.
Third
stage represents a first meeting, creating a powerful imprint upon the
relationship between mother and baby. When both are undrugged and quiet, fully
present and alert, new potentials are invoked, and we discover more about
ourselves, and the sacred origins of our capacity to love.
