28
Multiple Births
* Have appropriate resources
* Clamp or tie cord of first baby
* Assist with delivery of second baby
* Placenta and cord care are same as single delivery
* Keep babies and mother warm
29
Premature Birth
```
• Keep baby warm
• Keep airway clear
• Provide ventilations and chest
compressions
• Watch umbilical cord for bleeding
• Oxygen (blow by)
• Call ahead to emergency department
```
30
Meconium
* Don’t stimulate infant before suctioning
* Suction mouth, then nose
* Maintain open airway
* Provide ventilations and/or chest compressions
31
• Why is it important to have your partner or another person (birthing coach or other adult acceptable to the mother) observing as you help the mother through childbirth?
.
32
Emergencies in Pregnancy
* Excessive prebirth bleeding
* Ectopic pregnancy
* Seizures in pregnancy
* Miscarriage and abortion
* Trauma in pregnancy
* Stillbirths
* Accidental death of pregnant woman
33
Excessive Prebirth Bleeding
* Main sign is unusually profuse bleeding
* Abdominal pain may or may not be felt
* Assess for signs of shock
* High-concentration oxygen and transport
* Place sanitary napkin over vagina
34
Excessive Prebirth Bleeding
Abruptio Placentae: Uterine Bleeding Placenta, Bleeding may be minimal
35
Ectopic Pregnancy
.
36
Seizures in Pregnancy
* Existing preeclampsia
* Elevated blood pressure
* Excessive weight gain
* Excessive swelling to face, ankles hands, and feet
* Altered mental status or headache
37
Miscarriage and Abortion
* Cramping, abdominal pains
* Bleeding: moderate to severe
* Discharge of tissue and blood from vagina
38
Trauma in Pregnancy
* Pulse beats 10-15 faster than non pregnant women
* Blood loss may be 30%–35% before signs/symptoms appear
* Ask patient if she received blows to abdomen
39
Trauma in Pregnancy
Ruptured Uterus - Placenta, abdominal wall, torn edge of the uterus, uterus, bleeding
40
Stillbirths
* Do not resuscitate if it is obvious the baby died some time before birth
* Resuscitate if baby is born in cardiac or respiratory arrest
* Prepare to provide life support
* Emotional support for family
41
Accidental Death of Pregnant Woman
* Chance to save unborn child
* Begin CPR on mother immediately
* Continue CPR until emergency cesarean section can be performed or you are relieved in emergency department
42
Gyn emergencies:Vaginal Bleeding
Vaginal Bleeding
• Treat as potential life threat
• Check for associated abdominal pain
• Monitor for hypovolemic shock
43
Trauma to the External Genitalia - Female
* Observe MOI
* Look for signs of severe blood loss and shock
* Consider additional internal injuries
44
Sexual Assault
* Treat immediate life threats
* Do not disturb potential evidence
* Examine genitals only if severe bleeding is present
* Discourage bathing, voiding, or cleansing wounds
* Fulfill mandated reporting requirements
45
Think about it: when arriving at a crime scene, what are the key things to keep in mind as you respond - Sexual Assault
.
46
Chapter Review OB/Gyn
* Although birth is a natural process that usually takes place without complications, involvement of EMS usually indicates something unusual has happened.
* The EMT’s role at a birth is generally to provide reassurance and to assist the mother in the delivery of her baby.
47
Chapter Review OB/Gyn
• During normal delivery, determine if there should be immediate transport or if birth is
imminent and will take place at the scene.
• If birth is to take place at the scene, have equipment ready and appropriate resources on hand Always be prepared for resuscitation.
48
Chapter Review OB/Gyn
• Complications of delivery are a true emergency. Be prepared to initiate rapid transport.
• There may also be pre-delivery
emergencies or emergencies associated with pregnancy that you must be prepared to treat.
49
Chapter Review OB/Gyn
• Stillbirth and death of the mother and sexual assault are difficult emergencies
the EMT is occasionally called upon to manage. Emotional care for these issues may be as important as medical care.
50
Remember: OB/Gyn
Female reproductive organs present new anatomy and specific potential emergencies. EMTs should recognize the
different anatomy and be prepared to address reproductive emergencies.
• A growing fetus creates massive change to the mother’s body. All systems undergo major alterations.

51
Remember: OB/Gyn
* Assessment of the woman in labor is designed to predict imminent delivery and to recognize likely resuscitation.
* The urge to push and crowning indicate imminent delivery. Transport typically should be deferred for a home delivery.
52
Remember: OB/Gyn
* Lack of prenatal care, premature labor, multiple gestation, and underlying conditions indicate a likelihood of neonatal resuscitation.
* Childbirth requires a high level of personal protective equipment.
53
Remember: OB/Gyn
* The most important aspect of care for a neonate is keeping the baby warm. Resuscitation may be indicated by assessing breathing and heart rate.
* After delivery there are two patients to care for: the infant and the mother.
54
Remember: OB/Gyn
• EMTs should be familiar with the
pathophysiology and emergency treatment of the various complications of childbirth.
• Care of the sexual assault patient must include medical, legal, and psychological
considerations.
55
Questions to consider: OB/Gyn
* What is the difference between abrupt placenta and placentae previa?
* How do you care for a prolapsed cord?
* What do you do if the bag of water is still intact during delivery?
56
Critical Thinking: OB gyn
You are called to a pregnant woman in labor. During your evaluation you find that
it is the woman’s first pregnancy, the baby’s head is not crowning, and contractions are 10 minutes apart.
57
Critical Thinking: OB gyn
• You ask the mother if she feels the need to move her bowels, and she says no. Do you prepare for delivery at the scene? Or
do you transport the mother to the hospital?

day 1 mensturation
day 14 premium day for fertilization********
normally 28 day cycle
day 1 of bleeding
| day 14****egg released****
60
hormones thicken the wall of the uterus and prepare for implantation after fertilizaiton
.
61
implantation (pg 841)
placenta starts off first - exchanges nutrients and gases
drugs do pass the placenta
.
62
supine hypotensive syndrome*****
last trimester - 20 pounds
110/70 - flat on back
90/40 - what happened ?
Pg 843
elevate the spine board raise up the right side so they are laying on the left side
dizziness and a drop in BP caused when the mother is in a supine position & the weight of the uterus, infant, placenta, and amniotic fluid compresses the inferior vena cava, reducing return of blood to the heart
limits preload back to the heart and BP drops
63
First stage of labor
start of contractions to full dilation of the cervix 10cm**** (full dilation subjective)
64
Second stage of labor
full dilation of the cervix - baby enters the birth canal until birth
65
Third stage
birth of baby to birth of the placenta (afterbirth (placenta, umbilical cord, and some tissues from the amitotic sac and the lining of the uterus)
66
Once the baby delivers pack up and go. Save the placenta so it can be examined by the OB
.
67
rub the uterus - women is going to urinate as it is a natural diuretic
.
68
let the baby nurse to release pytocin...
.
69

what to ask
review the slides and review - assessing the woman in labor
- ask her name, age & expected due date
- seen a doctor
- when labor pains started and how often she is having pains
- has her bag of waters broken
- does she feel the need to push
- examine for crowning
- feel for uterine contractions
- take vital signs

begin transport immediately not in 10 minutes as the book says
allow to nurse and massage the fundus
85
normal blood loss
1200cc before it is a problem
86
breech
butt comes out
| mouth and nose between fingers to create an airway
87
limb presentation
treat with diesel - fly in helicopter
can not deliver in the field
call physician

93
868 emergencies in birth
.
94
Abruptio placentae
placenta separated abruptly from the uterine wall - complete separation baby will be dead within 4-6 minutes
marginal - the baby can survive
95
ectopic pregnancy
| tubal pregnancy
will rupture at 6 weeks - fetus dies, much bleeding, have to take the ovary and the tube
unexplained syncope - ectopic bleeding out
96
placental previa
.
97
baby can develop outside the uterus implant in the abdominal wall
.
98
eclampsia pg 868
```
tend to occur late in pregnancy - result of pre-eclampsia with hypertension
classic triad*************
-put on some weight
-edema
-BP is up (more than 140/90)
-protein in the urine
```
toxcemia of the pregnancy
which of the following is not*** a symptom of pre-ecalmpsia
not blood in the urine
99
only difference between eclamplsia and pre-ecampsia is a seizure***************
move from one to the other with a seizure
on the test
100
turn the lights down in the ambulance
keep it calm
make it a nice transport
to prevent seizure
| 20% chance of the neonate dying for eery seizure
101
trauma in pregnancy
review - goes into shock the body will shunt body from the baby to the mother
reduce blood flow to the fetus and it will die
102
still births
.
103
gyn emergencies
vaginal blending think ectopic
104
sexual assault
most often driven by law enforcement
| have to go the TGH or the crisis center
