Q

Functions of pelvic floor

A

• Supports the weight of the abdominal and
pelvic organs
• Responsible for the voluntary control of
elimination
• During childbirth:
• Supports the weight of uterus
• Control movements of the fetus through the birth
canal by contraction and relaxation

17
Q

Pelvic floor injury during childbirth will lead to
— and —

A

Incontinence, uterine prolapse

18
Q

Fetal skull

A

Bones are relatively thin and pliable
at birth

19
Q

Clinical significance of
• Sutures and fontanelles

A

allow overriding of
the fetal skull during labour
• Able to temporary alter the shape to pass
through the birth canal
• as guiding point in vaginal examination in
locating position

20
Q

Caput succedaneum

A

• Area of oedema over presenting part of fetus / newborn resulting from the
pressure against the cervix during labour
• Oedema occurs in the skin superficial to skull & periosteum
• Usually heal without any major medical intervention

21
Q

Cephalhaematoma

A

• Pressure during birth that cause bleeding between
periosteum (the membrane that covers the skull) & skull
• Reason for cephalhaematoma:
• Difficult or prolonged birth
• Cephalopelvic disproportion (the baby’s head is larger than the
mother’s pelvic opening)
• Big baby
• Abnormal presentation
• Use of birth-assisting tools such as forceps or vacuum delivery
• Usually heal without any major medical intervention
• If improperly treated:
• Permanent brain damage
• Anaemia
• Meningitis

22
Q

Treatment for Caput succedaneum

A

• Observational & Reassurance
• Majority of cases will self-resolve
within 48 hours
• Parent Education
• Care when handling infant’s head

23
Q

Treatment for Cephalohematoma

A

• Observational & Reassurance
• Nursing monitoring for growing size &
hyperbilirubinemia
• The swelling typically resolves itself
between 2 weeks to 6 months
• Parent Education
• Care when handling infant’s head
• Refer to appropriate Neonatal care
(e.g. phototherapy for
hyperbilirubinemia)

24
Q

Stage of fetal development (Total of 40 weeks)

A
  1. Pre-embryonic stage – first 2 weeks beginning with fertilization
  2. Embryonic stage – from week 3 to week 8
  3. Fetal stage – from week 8 till birth
25
Pre-embryonic stage
Period: Begins from fertilization to the 2nd week • Union of sperm and ovum forms a zygote (46 chromosomes) • Cell division continues to form a morula • The inner cell mass of morula is called blastocyst • The outer cell mass is called trophoblast • Implantation occurs 7-8 days after conception in the endometrium
26
Placenta
• Located at site where embryo attaches to uterine wall, normally in upper uterine segment • Purplish red in colour and round shape • Size: about 20 cm in diameter, 2.5-3 cm in thickness • Weight: about 1/6 of birth weight of baby (400-600 gm)
27
Functions of placenta
• Respiratory o actual pulmonary respiration does not take place o fetus obtains oxygen from maternal circulation by simple diffusion and give off CO2 to maternal circulation • Nutrition o all nutrients transport to fetus from mother through placenta: amino acid (tissue building), glucose (energy release), calcium and phosphate (bone and teeth development), iron (blood formation), water, vitamins • Excretion o Waste products excreted through maternal circulation (e.g. CO2, urea) • Protective barrier o Limited barrier to some bacterial infection and drug from mother o Protection from infection except virus & certain smaller organisms o Provide passive immunity to fetus e.g. some IgG can be passed on from the mother
28
Umbilical cord
• Extend from placenta to the umbilicus of fetus • About 50 cm in length, 2cm in diameter, surrounded by Wharton’s jelly Cord vessels (2A1V): • 2 umbilical arteries (carry deoxygenated blood) • 1 umbilical vein (carry oxygenated blood) Functions : • Transport oxygen and nutrients to fetus from mother • Transport waste products away from fetus to mother for excretion Cord abnormalities • True knot • Jelly cord
29
Three shunts are present in fetus before it is born to control circulation • All these shunts, together with umbilical vessels will close or become ligaments at birth after the newborn’s first breath; and clamping of umbilical cord
• 1. Ductus venosus • 2. Ductus arteriosus • 3. Foramen ovale
30
Fetal circulation during pregnancy
• Fetal oxygenation occurs in placenta through the umbilical cord • Fetal lungs and liver are non-functional until after birth
31
Functions of amniotic fluid
During pregnancy 1. maintain constant temperature 2. maintain fluid and electrolyte balance 3. permit symmetric growth and development 4. promote fetal movement 5. cushion the fetus from trauma 6. Prevent umbilical cord compression 7. provide some nutritive substances for fetus During labour (as long as the membranes remain intact) 1. equalize uterine pressure during contractions to protect the placenta and umbilical cord 2. aids effacement of cervix and dilatation of the cervical os
32
First fetal movement (______) started to be detected by primigravida mother: 18-21 weeks * Usually earlier in multiparity mother, can be as early as 13-16 weeks
quickening
33
Only _ sign can define a woman is ‘pregnant’
Positive
34
Probable signs
Positive pregnancy test (HCG urine test), Abdominal enlargement, Braxton Hicks contraction
35
Positive sign
Viable fetus is in uterus detected by ultrasound
36
Abortion Abortion (Miscarriage) • Loss of fetus early pregnancy before _ week of gestation
24
37
Signs and symptoms of abortion
• Vaginal bleeding • Abdominal cramping • Low back pain • Passage of product of gestation • Can be no symptoms
38
➢No /supportive treatment is required for _____ abortion
Threatened or complete
39
➢Surgical intervention to clear the product of gestation: ➢_____(D&C); ➢Suction and evacuation ➢Medical intervention: ➢_____ (oral or vaginal) to dilate the cervical and passage of the product of gestation
Dilation and curettage , Misoprostol
