13/42

STEP 6: Avoid supplementation

Give newborn infants no food or drink other than breast milk, unless

medically indicated Standards


14/42

Standard

No food or drink other than breast milk should be given to breastfed babies unless:

- there is an acceptable clinical reason, the baby is unable to breastfeed and there is no/insufficient breast

milk available

- the mother has made a fully informed choice to feed her baby other than from the breast.

contact both professional and voluntary help with breastfeeding afterdischarge from hospital.


23/42

Placenta


24/42

Placenta

The wordplacenta comes from the Latin forcake.

The placenta is an organ that connects the developing fetus to theuterine wall to allow nutrient uptake, waste elimination, and gas exchange

via the mother's blood supply. The placenta develops from the same sperm

and egg cells that form the fetus, and functions as a fetomaternal organ with

two components, the fetal part (Chorion frondosum), and the maternal part

(Decidua basalis).


25/42

StructureIn humans, the placenta averages 22 cm (9 inch) in

length and 22.5 cm (0.81 inch) in thickness (greatest

thickness at the center and become thinner peripherally). It

typically weighs approximately 500 grams (1 lb). It has a

dark reddish-blue or maroon color. It connects to the fetus byan umbilical cord of approximately 5560 cm (2224 inch) in

length that contains two arteries and one vein. The umbilical

cord inserts into the chorionic plate (has an eccentric

attachment). Vessels branch out over the surface of the

placenta and further divide to form a network covered by a

thin layer of cells. This results in the formation of villous tree

structures. On the maternal side, these villous tree structuresare grouped into lobules called cotyledons. In humans the

placenta usually has a disc shape, but size varies vastly

between different mammalian species.


26/42

DevelopmentalThe placenta begins to develop upon implantation

of the blastocyst into the maternal endometrium. The

outer layer of the blastocyst becomes the

trophoblast which forms the outer layer of the placenta.

This outer layer is divided into two further layers: the

underlying cytotrophoblast layer and the overlying

syncytiotrophoblast layer. The syncytiotrophoblast is a

multinucleate continuous cell layer which covers the

surface of the placenta. It forms as a result of

differentiation and fusion of the underlying

cytotrophoblast cells, a process which continues

throughout placental development. The

syncytiotrophoblast (otherwise known as syncytium),

thereby contributes to the barrier function of the placenta.

The placenta grows throughout pregnancy.Development of the maternal blood supply to the placenta

is suggested to be complete by the end of the first

trimester of pregnancy (approximately 1213 weeks


27/42

Function1.Nutrition and immunity

The perfusion of the intervillous spaces of the placenta with maternal blood allows the transfer of nutrients and

oxygen from the mother to the fetus and the transfer of waste products and carbon dioxide back from the fetus to the mother.

Nutrient transfer to the fetus is both actively and passively mediated by proteins called nutrient transporters that are expressed

within

2. Endocrine function

In humans, aside from serving as the conduit for oxygen and nutrients for fetus, placenta secretes hormone that is

importantduring pregnancy.

3. Human Chorionic Gonadotropin (hCG)

The first placental hormone produced is hCG, which can be found in maternal blood and urine as early as the first

missed menstrual period (shortly after implantation has occurred) through about the 100th day of pregnancy. This is the

hormone analyzed by pregnancy test; a false-negative result from a pregnancy test may be obtained before or after this

period. Women's blood serum will be completely negative for hCG by one to two weeks after birth. hCG testing is proof that

all placental tissue is delivered. hCG is only present during pregnancy because it is secreted by the placenta, which of course

is present only during pregnancy. hCG also ensures that the corpus luteum continue to secrete progesterone and estrogen.

Progesterone is very important during pregnancy because when its secretion decreases, endometrial lining will slough off and

pregnancywill be lost. hCG suppresses the maternal immunologic responseso that placenta is not rejected.


28/42

Function4. Human Placental Lactogen (hPL[Human Chorionic Somatomammotropin])

This hormone is lactogenic and growth-promoting properties. It promotes mammary gland growth in preparation for

lactation in the mother. It also regulates maternal glucose, protein, fat levels so that this is always available to the fetus.

5. Estrogen

It is referred to as the "hormone of woman" because it influences the female appearance. It contributes to thewoman's mammary gland development in preparation for lactation and stimulates uterine growth to accommodate growing

fetus.

6. Progesterone

This is referred to as the "hormone of mothers" because it is necessary to maintain endometrial lining of the uterus

during pregnancy. This hormone prevents preterm labor by reducing myometrial contraction. This hormone is high during

pregnancy.

7. Other functions

The placenta also provides a reservoir of blood for the fetus, delivering blood to it in case of hypotension and vice

versa, comparable to a capacitor.


29/42

PlacentalAbnormalities


30/42

1. Placenta PreviaPlacenta previa is defined as implantation of the placenta in the lower uterine

segment in advance of the fetal presenting part. The placenta either totally or

partially lies within the lower uterine segment. Placenta previa complicates

approximately 0.3%-0.5% of pregnancies or about 4.8 per 1,000 deliveries. The riskof recurrent placenta previa is as high as 4% to 8%. The risk of placenta previa

increases with the number of prior cesarean sections, rising to 10% with four or

more. Although some distinctions in outcome may be made among the different

degrees of true placenta previa, all are potentially associated with life-threatening

hemorrhage during labor. The degree of placenta previa cannot alone predict the

clinical course accurately, nor can it serve as the sole guide for managementdecisions. Thus, the importance of such classifications has diminished.


31/42

Traditionally, placenta previa has been categorized into 4 types (1):

1. Complete placenta previa: where the placenta completely covers the internal os;

2. Partial placenta previa: where the placenta partially covers the internal os.

Thus, this scenario occurs only when the internal os is dilated to some degree;

3. Marginal placenta previa: where placenta just reaches the internal os, but does not cover it;4. Low-lying placenta: where placenta extends into the lower

uterine segment but does not reach the internal os.


32/42

2. Abruptio Placentae

The term abruptio placentae denote separation of a normally implanted placenta prior to the birth of the fetus. Thediagnosis is most commonly made in third trimester, but the term may be used after the 20th week of pregnancy when the

clinical and pathologic criteria are met. This is uniquely dangerous condition to both the mother and the fetus because of its

pathologic sequelae. Placental separation is a serious complication of pregnancy. The reported incidence varies from 0.49%

to 1.29% with a mean incidence of 0.83% or one per 120 deliveries.


33/42

3. Vasa PreviaVasa previa refers to fetal vessels running through the membranes

over the cervix and under the fetal presenting part, unprotected by placenta

or umbilical cord. The condition usually results either from a velamentous

insertion of the cord into the membranes rather than the placenta or from

vessels running between lobes of a placenta with one or more accessory lobe.

It is a condition which, if undiagnosed is associated with a perinatalmortality of approximately 60%. The condition is important because, when

the membranes rupture, spontaneously or artificially, the fetal vessels

running through the membranes have a high risk of concomitant rupture,

frequently resulting in fetal exsanguination and death. The incidence of vasa

previa is approximately 1 in 2,500 deliveries. Risk factors for the condition

include a second-trimester low-lying placenta (even if the "low lying"

placenta or placenta previa resolves in the third-trimester), pregnancies in

which the placenta has accessory lobes, multiple pregnancies, andpregnancies resulting from in vitro fertilization.

Special Structures in Fetal

Circulation

PlacentaWhere gas exchange takes place during fetal life

Ductus VenosusCarry oxygenated blood from umbilical

vein to inferior vena cava, bypassing fetal liver


36/42

Umbilical ArteriesCarry unoxygenatedblood from the fetus to

Umbilical VeinBrings oxygenated blood coming from the placenta

to the fetus

Ductus ArteriosusCarry oxygenated blood from pulmonary

artery to aorta, bypassing fetal lungs.

Foramen OvaleConnects the left and right atrium.

It pushes blood from the right atrium to the left

atrium so that blood can be supplied to brain,

heart and kidney

Heart

Is to pump blood through blood vesselsto the body's cells


38/42

How does the fetal circulatory system work?

During pregnancy, the fetal circulatory system works differently than after birth:

The fetus is connected by the umbilical cord to the placenta, the organ that

develops and implants in the mother's uterus during pregnancy.

Through the blood vessels in the umbilical cord, the fetus receives all the

necessary nutrition, oxygen, and life support from the mother through the

placenta.

Waste products and carbon dioxide from the fetus are sent back through the

umbilical cord and placenta to the mother's circulation to be eliminated.


39/42


40/42

Inside the fetal heart:

Blood enters the right atrium, the chamber on the upper right side of the heart. Most

of the blood flows to the left side through a special fetal opening between the left

and right atria, called the foramen ovale.

Blood then passes into the left ventricle (lower chamber of the heart) and then to the

aorta, (the large artery coming from the heart).\From the aorta, blood is sent to the

heart muscle itself in addition to the brain and arms. After circulating there, the

blood returns to the right atrium of the heart through the superior vena cava.

About one-third of the blood entering the right atrium does not flow through theforamen ovale, but, instead, stays in the right side of the heart. This blood enters the

right ventricle from the right atrium, then exits the right ventricle to end up in,

eventually flowing into the pulmonary artery. From there, some of the blood will

travel to the lungs. The majority of the blood in the pulmonary artery, however,

enters the descending aorta through a special artery called the patent ductus

arteriosus (PDA). It then travels through smaller vessels to reach back into the

placenta.

Because the placenta does the work of exchanging oxygen (O2) and carbon dioxide

(CO2) through the mother's circulation, the fetal lungs are not used for breathing.Instead of blood flowing to the lungs to pick up oxygen and then flowing to the rest

of the body, the fetal circulation shunts (bypasses) most of the blood away from the

lungs. In the fetus, blood is shunted from the pulmonary artery to the aorta through

the patent ductus arteriosus.


41/42

Blood circulation after birth:

With the first breaths of air the baby takes at birth,

the fetal circulation changes. A larger amount of

blood is sent to the lungs to pick up oxygen.

Because the patent ductus arteriosus (the normalconnection between the aorta and the pulmonary

artery) is no longer needed, it begins to narrow and

close off.

The circulation in the lungs increases and more

blood flows into the left atrium of the heart. This

increased pressure causes the foramen ovale to

close and blood circulates normally.
