Obstetric Nursing - Intrapartal Period
Nursing lectures is proud to share with you a comprehensive review about the Intrapartal period. Included in this lecture are the following
- A. Admitting the laboring Mother:
- Personal Data: name, age, address, etc
- Baseline Data: v/s especially BP, weight
- Obstetrical Data: gravida # preg, para- viable preg, – 22 – 24 wks
- Physical Exams,Pelvic Exams
- B. Basic knowledge in Intrapartum .
- A. Theories of the Onset of Labor
- 1.) uterine stretch theory
- -( any hollow organ when stretched, will always contract & expel its content).
- – contraction action.
- 2.) Oxytocin Theory
- – post pit gland releases oxytocin. Hypothalamus produces oxytocin
- 3.) Prostaglandin Theory
- – stimulation of arachidonic acid.
- – prostaglandin- contraction
- 4.) progesterone theory
- – before labor, decrease progesterone will stimulate contractions & labor.
- 5.) Theory of Aging placenta
- – life span of placenta 42 wks. At 36 wks degenerates (leading to contraction – onset labor).
- B. The 4 P’s of labor
- Passenger
- a. Fetal head
- – is the largest presenting part
- – common presenting part
- ¼ of its length.
- Bones – 6 bones
- S–sphenoidF –frontal –sinciput
- E–ethmoid O–occipital–occiput
- T–temporal P– parietal 2 x
- Measurement fetal head:
- transverse diameter – 9.25cm
- biparietal – 9.5cm
- largest transverse
- bitemporal 8 cm
- Sutures
- – intermembranous spaces that allow molding.
- 1.Sagittal Suture
- – connects 2 parietal bones .
- 2.Coronal suture
- – connects parietal & frontal bone (crown).
- 3.Lambdoidal suture
- – connects occipital & parietal bone.
- Moldings: the overlapping of the sutures of the skull to permit passage of the head to the pelvis
- Fontanels:
- 1.Anterior fontanel
- – bregma, diamond shape, 3 x 4 cm,( > 5 cm – hydrocephalus), 12 – 18 months after birth- close.
- 2.Posterior fontanel or lambda
- – triangular shape, 1 x 1 cm. Closes – 2 – 3 months.
- 4. Anteroposterior diameter
- - suboccipitobregmatic 9.5 cm, complete flexion, smallest AP
- occipitofrontal 12cm partial flexion
- occipitomental – 13.5 cm hyper extension submentobregmatic-face presentation
- 2. Passageway
- Mom
- 1.) <>
- 2.) <>
- 3.) Underwent pelvic dislocation
- Pelvis
- 4 Main Pelvic Types
- Gynecoid
- – round, wide, deeper most suitable (normal female pelvis) for pregnancy.
- 2. Android
- – heart shape “male pelvis”- anterior part pointed, posterior part shallow.
- 3. Anthropoid
- – oval, ape like pelvis, oval shape, AP diameter wider transverse narrow
- 4. Plattypelloid
- – flat AP diameter – narrow, transverse – wider
- 2 hip bones –2 innominate bones
- 3 Parts of 2 Innominate Bones
- Ileum
- – lateral side of hips
- -iliac crest
- – flaring superior border forming prominence of hips.
- Ischium
- – inferior portion
- - ischial tuberosity where we sit
- – landmark to get external measurement of pelvis
- Pubes
- – ant portion – symphysis pubis junction between 2 pubes
- 1 sacrum
- – post portion – sacral prominence – landmark to get internal measurement of pelvis
- 1 coccyx
- – 5 small bones compresses during vaginal delivery
- Important Measurements
- Diagonal Conjugate
- – measure between sacral promontory and inferior margin of the symphysis pubis.
- Measurement: 11.5 cm - 12.5 cm
- - basis in getting true conjugate. (DC – 11.5 cm=true conjugate)
- 2. True conjugate/conjugate vera
- – measure between the anterior surface of the sacral promontory and superior margin of the symphysis pubis. Measurement: 11.0 cm.
- 3. Obstetrical conjugate
- – smallest AP diameter. Pelvis at 10 cm or more.
- Tuberoischi Diameter
- – transverse diameter of the pelvic outlet. Ischial tuberosity – approximated with use of fist – 8 cm & above.
- 3. Power
- – the force acting to expel the fetus and placenta – myometrium – powers of labor.
- 4. Psyche/Person

- Suction cup is placed against the fetal occiput.
- INFERTILITY
- Inability to achieve pregnancy. Within a year of attempting it
- Manageable
- In order to get pregnant:
- 1. A woman must release an egg from one of her ovaries (ovulation).
- 2. The egg must go through a fallopian tube toward the uterus (womb).
- 3. A man's sperm must join with (fertilize) the egg along the way.
- 4. The fertilized egg must attach to the inside of the uterus (implantation).
- Is infertility a common problem?
- Is infertility just a woman's problem?
- NO
- What causes infertility in men?
- Infertility in men is most often caused by:
- problems making sperm -
- problems with the sperm's ability to reach the egg and fertilize it
- Sometimes a man is born with the problems that affect his sperm. Other times problems start later in life due to illness or injury.
- What increases a man's risk of infertility?
- The number and quality of a man's sperm can be affected by his overall health and lifestyle.
- What causes infertility in women?
- Problems with ovulation account for most cases of infertility in women. Without ovulation, there are no eggs to be fertilized.
- Less common causes of fertility problems in women include:
- blocked fallopian tubes physical problems with the uterus
- uterine fibroids
- What things increase a woman's risk of infertility?
- Many things can affect a woman's ability to have a baby. These include:
- 1.age
- 2.stress
- 3.poor diet
- 4.athletic training
- How long should women try to get pregnant before calling their doctors?
- Some health issues also increase the risk of fertility problems. So women with the following issues should speak to their doctors as soon as possible :
- irregular periods or no menstrual periods
- very painful periods
- endometriosis
- pelvic inflammatory disease
- more than one miscarriage
- How will doctors find out if a woman and her partner have fertility problems?
- For a woman, the first step in testing is to find out if she is ovulating each month.
- Some common tests of fertility in women include :
- Hysterosalpingography : In this test, doctors use x-rays to check for physical problems of the uterus and fallopian tubes.
- Laparoscopy:
- During this surgery doctors use a tool called a laparoscope to see inside the abdomen.
- How do doctors treat infertility?
- Infertility can be treated with medicine, surgery, artificial insemination or assisted reproductive technology.
- Doctors often treat infertility in men in the following ways:
- Sexual problems: Behavioral therapy and/or medicines can be used in these cases.
- Too few sperm:, doctors can surgically remove sperm from the male reproductive tract. Antibiotics can also be used to clear up infections affecting sperm count.
- Intrauterine insemination (IUI) - is known by most people as artificial insemination.
- IUI is often used to treat:
- mild male factor infertility
- women who have problems with their cervical mucus
- couples with unexplained infertility
- What medicines are used to treat infertility in women?
- Some common medicines used to treat infertility in women include:
- 1.Clomiphene citrate ( Clomid ): This medicine causes ovulation by acting on the pituitary gland.
- 2.Human menopausal gonadotropin or hMG ( Repronex, Pergonal ): This medicine is often used for women who don't ovulate due to problems with their pituitary gland.
- 3.Follicle-stimulating hormone or FSH ( Gonal-F, Follistim ): FSH works much like hMG..
- 4.Gonadotropin-releasing hormone (Gn-RH) analog : These medicines are often used for women who don't ovulate regularly each month.
- 5. Metformin ( Glucophage ): Doctors use this medicine for women who have insulin resistance and/or Polycystic Ovarian Syndrome (PCOS) . This drug helps lower the high levels of male hormones in women with these conditions.
- 6. Bromocriptine ( Parlodel ): This medicine is used for women with ovulation problems due to high levels of prolactin.
- Many fertility drugs increase a woman's chance of having twins, triplets or other multiples.
- What is assisted reproductive technology (ART)?
- Assisted reproductive technology (ART) is a term that describes several different methods used to help infertile couples.
- How often is assisted reproductive technology (ART) successful?
- age of the partners
- reason for infertility
- clinic
- type of ART
- if the egg is fresh or frozen
- if the embryo is fresh or frozen
- What are the different types of assisted reproductive technology (ART)?
- Common methods of ART include:
- 1. In vitro fertilization (IVF) . Once mature, the eggs are removed from the woman. They are put in a dish in the lab along with the man's sperm for fertilization. After 3 to 5 days, healthy embryos are implanted in the woman's uterus.
- 2. Zygote intrafallopian transfer (ZIFT) or Tubal Embryo Transfer - Fertilization occurs in the laboratory. Then the very young embryo is transferred to the fallopian tube instead of the uterus.
- 3.Gamete intrafallopian transfer (GIFT) involves transferring eggs and sperm into the woman's fallopian tube.
- 4. Intracytoplasmic sperm injection (ICSI)
- In ICSI, a single sperm is injected into a mature egg. Then the embryo is transferred to the uterus or fallopian tube.
- 2 types of infertility
- 1.) primary
- 2.) Secondary
- Sims Huhner test
- Infertility
- Normal: cervical mucus must be stretchable 8 – 10 cm
- Best criteria- sperm motility for impotency
- Infertility
- Mgt:
- GIFT= Gamete Intra Fallopian Transfer for low sperm count
- Mom: anovulation – no ovulation
- hyperprolactinemia
- Tubal Occlusion – tubal blockage
- = dx: hysterosalphingography
- Mgt: IVF – invitrofertilization
