Q

Spontaneous Abortion

A

Recognized pregnancy loss before 20th week.
Most common complication of early pregnancy.
8-20% of clinically recognized pregnancies less than 20 weeks of gestation will undergo spontaneous abortion.
80% of these occur in the first 12 weeks of gestation.

Q

What is Rh Incompatibility

A

Rhesus (Rh) negative woman who deliver an Rh positive baby or who are otherwise exposed to Rh positive RBC’s are at risk for developing anti-Rh antibodies.
Rh positive fetuses/neonates of these mothers are at risk for developing hemolytic disease of the fetus and newborn

80
Q

What are the Rh Antigens

A
Rh negative (no D antigen)
Rh positive (contains D antigen)
D antigens are highly immunogenic
Individuals who do not produce the D antigen (ie Rh negative) will produce anti-D if they encounter the D antigen (become Rh sensitized)
81
Q

What occurs during the second pregnancy for Rh incompatability?

A
1st pregnancy mom built up antibodies
2nd pregnancy:
IgG antibodies cross the placenta
Maternal antibodies attach to fetal RBC antigen
Hemolysis of fetal RBC’s
82
Q

What happens to the baby with prolonged hemolysis?

A
Hepatomegaly
Splenomegaly
Hyperbilirubinemia
fetal jaundice
hydrops fetalis
83
Q

How to diagnose Rh incompatability?

A

Detection of anti-Rh(D) antibody in maternal serum by performing a type and antibody screen
The antibody titer is then quantified.
If titer is above critical level further evaluation is indicated
The titer below which the fetus will not die from hemolytic disease is usually 1:16

84
Q

What is hydrops fetalis?

A

serious condition in which abnormal amounts of fluid build up in two or more body areas of a fetus or newborn.

85
Q

What does hyrops fetalis cause?

A
Hepatosplenomegaly
Portal hypertension
Ascites
Fetal hypoxia
Anemia
Congestive cardiac failure

Give Rh Immunoglobin:
Pregnancy loss
Termination of pregnancy
Procedure-amniocentesis
Any bleeding during pregnancy
At 28-29 weeks
Following delivery if baby is Rh positive

Abruptio Placentae

A

The separation of the placenta from its site of implantation before delivery of the fetus.
Also termed Placental Abruption

109
Q

Abruptio Placentae patho

A

The immediate cause of the premature separation of the placenta is rupture of the maternal vessels in the decidua basalis, where it interferes with the anchoring villi of the placenta
unknown etiology

110
Q

Abruptio Placentae signs and symptoms

A
Abrupt onset of vaginal bleeding with abdominal pain
Bleeding can be mild or profuse
Contractions
Uterus is firm, may be rigid & tender
Maternal hypotension
Fetal distress
DIC
111
Q

Abruptio Placentae diagnosed by

A

U/S and clinically

112
Q

Abruptio Placentae

A

Nonsevere abruption @ 34 – 36 weeks – deliver
Nonsevere abruption @ 36 weeks - deliver
**Most by C-section

113
Q

Dystocia

A

difficult labor & is characterized by abnormally slow labor
Disproportion between the presenting part of the fetus and the birth canal
It is a consequence of 4 distinct abnormalities that may exist singly or in combination

114
Q

What can cause dystocia?

A

abnormalities involving the cervix, uterus, fetus, maternal bony pelvis or other obstructions in the birth canal
ACOG simplified into 3 categories:
Abnormalities of the powers (uterine contractility & maternal expulsive effort)
Abnormalities involving the passenger (the fetus)
Abnormalities of the passage (the pelvis)

115
Q

When does labor begin

A

contracting every 5 min

116
Q

What are 2 types of uterine dysfunction?

A

Hypotonic uterine dysfunction mild contractions

Hypertonic uterine dysfunction uterus contracts and is “too contracted”

117
Q

What are 3 causes of uterine dysfunction?

A

Epidural analgesia slow labor down
Chorioamnionitis
infection

118
Q

What is Fetopelvic Disproportion

A

Contracted pelvis

Excessive fetal size small pelvis

119
Q

What are second stage disorders of dystocia?

A

women is not pushing forcefully
Causes of inadequate expulsive forces
Heavy sedation
Conduction analgesia

120
Q

Maternal-Fetal Effects of Dystocia

A

Intrapartum infection
Uterine rupture rare
Fistula formation due to pushing for long periods and the baby is larger causing lacerations to the vagina + rectum
Pelvic floor injury

121
Q

What is fetal acidemia classified as

A

is an umbilical arterial blood pH of <7.00

122
Q

What is the rationale for monitoring fetal heart rate?

A

FHR patterns are indirect markers of the fetal cardiac and medullary responses to blood volume changes, acidemia and hypoxemia, since the brain modulates heart rate

123
Q

FHR Patterns based on category?

A

Category I Observation
Category II Intervention, no improvement deliver
Category III Deliver
Change the position of the patient with category II

124
Q

Cesarean section

A

Refers to the delivery of a baby through surgical incisions in the abdomen and uterus.
Categorized as either primary or repeat
C/S rate in the U.S. is about 33%

125
Q

3 most common indications account for about 80% of these deliveries

A

Failure to progress during labor (35%) dystocia
Nonreassuring fetal status (24%)
Fetal malpresentation (19%) breach or a face presentation

126
Q

What are some less common causes for C-Section

A

Abnormal placentation (eg. placenta previa)
Maternal infection (eg. Genital HSV active)
Multiple gestation
Cord prolapse cord comes out first
Fetal bleeding diathesis
Suspected macrosomia (5000 gms in woman without DM, 4500 gms in woman with DM)
Mechanical obstruction to vaginal birth

127
Q

What is used for anesthesia during C-Section?

A

Anesthesia
Spinal(best cause immediate) or epidural 30 min to go into effect
General

128
Q

What are the 2 types of incisions for C-Section

A

External incision
Low transverse
Vertical— only time is if she already had this
Internal incision
Low transverse
Vertical (This is the incision that matters for subsequent pregnancies)

129
Q

Vaginal Birth After Cesarean (VBAC) requirements?

A
Vertex
Only one prior C/S
Previous C/S  > 18 months 
Full consent of patient
Available OR for emergency C/S
Blood available
No pitocin
130
Q

Postpartum Hemorrhage

A

Obstetrical emergency that can follow a vaginal delivery or cesarean section
Major cause of maternal morbidity
Top 3 causes of maternal mortality
excessive bleeding that makes the patient symptomatic
Occurs in 1-5% of deliveries

131
Q

2 types of postpartum hemorrhage

A

Primary (first 24 hours after delivery)

Secondary or delayed (24 hours to 12 weeks after delivery)

132
Q

What are some of the causes of postpartum hemorrhage

A
Overdistension of uterus
Uterine infection
Uterine relexants
Uterine fatigue
Uterine inversion
Retained placenta
trauma
coag deficiencys
133
Q

What are some risk factors for postpartum hemorrhage?

A
Retained placenta
Failure to progress during second stage of labor
Placenta accreta
Lacerations
Instrumental delivery
Large for gestational age
Hypertensive disorders
Induction & augmentation of labor
134
Q

What is the goal of postpartum hemorrhage?

A

Restore or maintain adequate circulatory volume
Restore or maintain adequate tissue oxygenation
Reverse or prevent coagulopathy
