Chapter 20

Page 2: Obstetric and Gynecologic Emergencies

Three Stages of Labor

• First stage– Dilation of the cervix

• Second stage– Expulsion of the infant

• Third stage– Delivery of the placenta

Page 3: Obstetric and Gynecologic Emergencies

Predelivery Emergencies

• Preeclampsia– Headache, vision disturbance, edema, anxiety,

high blood pressure• Eclampsia– Convulsions resulting from hypertension

• Supine hypotensive syndrome– Low blood pressure from lying supine

Page 4: Obstetric and Gynecologic Emergencies

Hemorrhage

• Vaginal bleeding that occurs before labor begins

• If present in early pregnancy, it may be a spontaneous abortion or ectopic pregnancy.

Page 5: Obstetric and Gynecologic Emergencies

Ectopic Pregnancy

• Pregnancy outside of the uterus• Should be considered for any woman of

childbearing age with unilateral lower abdominal pain and missed menstrual period

• History of PID, tubal ligation, or previous ectopic pregnancy

Page 6: Obstetric and Gynecologic Emergencies

Placenta Problems• Placenta abruptio– Premature separation of the placenta

• Placenta previa– Development of placenta over the cervix

Page 7: Obstetric and Gynecologic Emergencies

Gestational Diabetes

• Develops only during pregnancy.• Treat as regular patient with diabetes.

Page 8: Obstetric and Gynecologic Emergencies

Scene Size Up:

• Woman’s balance is altered. Be aware for falls and the need for spinal stabilization.

• Use BSI.• Usual threats to your safety still exist.• Be calm. Protect the mother and the child.

Page 9: Obstetric and Gynecologic Emergencies

Initial Assessment

• Is the mother in active labor?• Evaluate trauma or medical problems first.• Treat ABCs in line with local protocols.

Page 10: Obstetric and Gynecologic Emergencies

Transport Decision• If delivery is imminent, prepare for delivery in warm, private

location.• If delivery is not imminent, transport on left side if in last two

trimesters of pregnancy.• If the patient was subject to spinal injury, stabilize and prop

backboard with towel roll on right side.

Page 11: Obstetric and Gynecologic Emergencies

Focused History/ Physical Exam

• Obtain full SAMPLE history, and also:– Prenatal history– Complications during pregnancy– Due date– Number of babies (twins)– Drugs or alcohol– Water broken– Green fluid (meconium)

Page 12: Obstetric and Gynecologic Emergencies

Focused Physical Exam

• Mainly abdomen and delivery of fetus• Based on her chief complaints and history• Pay close attention to tachycardia,

hypotension, or hypertension.

Page 13: Obstetric and Gynecologic Emergencies

Interventions

• Childbirth is natural, does not require intervention in most cases.

• Treating the mother will benefit the baby.

Page 14: Obstetric and Gynecologic Emergencies

Detailed Physical Exam

• Only if other treatments are not required

Page 15: Obstetric and Gynecologic Emergencies

Ongoing Assessment

• Continue to reassess the patient for changes in vital signs. Watch for hypoperfusion.

• Notify hospital of your preparations for delivery.

• Document carefully, especially baby’s status.• Obstetrics is one of the most litigated

specialties in medicine.

Page 16: Obstetric and Gynecologic Emergencies

When to Consider Field Delivery

• Delivery can be expected within a few minutes

• A natural disaster or other catastrophe makes it impossible to reach a hospital

• No transportation is available

Page 17: Obstetric and Gynecologic Emergencies

Preparing for Delivery

• Use proper BSI precautions.• Be calm and reassuring while protecting the

mother’s modesty.• Contact medical control for a decision to

deliver on scene or transport.• Prepare OB kit.

Page 18: Obstetric and Gynecologic Emergencies

Positioning for Delivery

Page 19: Obstetric and Gynecologic Emergencies

Delivering the Baby

• Support the head as it emerges.

• Once the head emerges, the shoulders will be visible.

• Support the head and upper body as the shoulders deliver.

• Handle the infant firmly but gently as the body delivers.

• Clamp the cord and cut it.

Page 20: Obstetric and Gynecologic Emergencies

Complications With Normal Vaginal Delivery

• Unruptured amniotic sac– Puncture the sac and push it away from the baby.

• Umbilical cord around the neck– Gently slip the cord over the infant’s head.– It may have to be cut.

Page 23: Obstetric and Gynecologic Emergencies

Postdelivery Care

• Immediately wrap the infant in a towel with the head lower than the body.

• Suction the mouth and nose again.

• Clamp and cut the cord.

• Ensure the infant is pink and breathing well.

Meconium

Page 25: Obstetric and Gynecologic Emergencies

Delivery of Placenta

• Placenta is attached to the end of the umbilical cord.

• It should deliver within 30 minutes.• Once the placenta delivers, wrap it and take to

the hospital so it can be examined.• If the mother continues to bleed, transport

promptly to the hospital.

Neonatal Resuscitation

• Neonatal Resuscitation

Page 28: Obstetric and Gynecologic Emergencies

Giving Chest Compressions to an Infant

• Find the proper position– Just below the nipple line– Middle third of the sternum

• Wrap your hands around the body, with your thumbs resting at that position.

• Press your thumbs gently against the sternum, compressing 1/3 the depth of the chest

• Ventilate with a BVM device after every third compression.• 90 compressions to 30 ventilations per minute• Continue CPR during transport

Page 29: Obstetric and Gynecologic Emergencies

Breech Delivery• Presenting part is the buttocks

or legs.• Breech delivery is usually slow,

giving you time to get to the hospital.

• Support the infant as it comes out.

• Make a “V” with your gloved fingers then place them in the vagina to prevent it from compressing infant’s airway.

Page 30: Obstetric and Gynecologic Emergencies

Breech Presentation

Page 31: Obstetric and Gynecologic Emergencies

Rare Presentations

• Limb presentation– This is a very rare occurrence.– This is a true emergency that

requires immediate transport.• Prolapsed cord– Transport immediately.– Place fingers into the mother’s

vagina and push the cord away from the infant’s face.

Excessive Bleeding

• Bleeding always occurs with delivery but should not exceed 500 mL.

• Massage the mother’s uterus to slow bleeding.

• Treat for shock.• Place pad over vaginal opening.• Transport to hospital.

Page 35: Obstetric and Gynecologic Emergencies

Spina Bifida

• Defect in which the portion of the spinal cord or meninges may protrude outside the vertebrae or body.

• Cover area with moist, sterile compresses to prevent infection.

• Maintain body temperature by holding baby against an adult for warmth.

Abortion (Miscarriage)

• Delivery of the fetus or placenta before the 20th week

• Infection and bleeding are the most important complications.

• Treat the mother for shock.• Transport to the hospital.• Bring tissue that has passed through the

vagina to the hospital.

Abortion or miscarriage

Page 39: Obstetric and Gynecologic Emergencies

Twins

• Twins are usually smaller than single infants.• Delivery procedures are the same as that for

single infants.• There may be one or two placentas to deliver.

Twins

Page 41: Obstetric and Gynecologic Emergencies

Delivering an Infant of an Addicted Mother

• Ensure proper BSI precautions

• Deliver as normal.

• Watch out for severe respiratory depression and low birth weight.

• Infant may require immediate care.

Page 42: Obstetric and Gynecologic Emergencies

Premature Infants and Procedures

• Delivery before 8 months or weight less than 5 lb at birth.– Keep the infant warm.– Keep the mouth and

nose clear of mucus.– Give oxygen.– Do not infect the infant.– Notify the hospital.

Page 43: Obstetric and Gynecologic Emergencies

Fetal Demise

• An infant that has died in the uterus before labor

• This is a very emotional situation for family and providers.

• The infant may be born with skin blisters, skin sloughing, and dark discoloration.

• Do not attempt to resuscitate an obviously dead infant.

Fetal Demise

Page 45: Obstetric and Gynecologic Emergencies

Delivery Without Sterile Supplies

• You should always have goggles and sterile gloves with you.

• Use clean sheets and towels.• Do not cut or clamp umbilical cord.• Keep placenta and infant at same level

Gynecologic Emergencies

• Do not examine genitalia unless there is obvious bleeding.

• Leave any foreign bodies in place, after packing with bandages

• Treat as any other patient with blood loss.
