Transcript

Slide 1-

By: Darryl Jamison Macon County EMS Training Coordinator OB/GYN EMERGENCIES
Slide 2-

Describe fetal-maternal blood flow and the role of the placenta. Identify the details of the history that should be obtained from an obstetrical patient. Discuss the effects of pregnancy on pre-existing conditions such as diabetes, HTN, and cardiac problems. Define the following terms: Spontaneous abortion; criminal abortion; therapeutic abortion Objectives
Slide 3-

Describe the pathophysiology and management of the following conditions: Ectopic pregnancy Abruptio placenta Placenta previa Objectives cont
Slide 4-

Objectives cont. Distinguish between pregnancy-induced hypertension, preeclampsia, eclampsia. Describe management of prolapsed cord. Describe management of breech presentation Describe management of multiple-birth presentation Describe the pathophysiology and management of the following conditions: Postpartum hemorrhage Uterine inversion Uterine rupture
Slide 5-

Fetal-Maternal Blood flow Blood flows from the placenta in through the umbilical vein which connects to the inferior vena cava then to the heart Routed around the lungs through the ductus arteriosus, into the aorta and then throughout the baby. Deoxygenated blood is filtered by the liver and then transported to the mother
Slide 6-

Role of the placenta Provides for exchange of respiratory gases. Transport of the nutrients Excretion of wastes Transfer of heat The placenta becomes an active endocrine gland, producing several important hormones
Slide 7-

History Should include: Gravidity—number of pregnancies Para—number of viable fetus delivered Length of gestation Estimated date of confinement Previous complications with pregnancies When did pain start Sudden or slow in onset Duration, location, radiation Is it regular Spotting Proper prenatal care If active labor, question push or bowel movement
Slide 8-

Diabetes Patients have to be placed on insulin—medication will pass to the fetus Effects on baby—tend to be larger in size Tend to have trouble maintaining body temp. And subject to hypoglycemia
Slide 9-

Hypertension Generally speaking bp is lower in pregnancy than non-pregnancy Preexisting hypertension is exacerbated Persistent HTN adversely affects placental size Leading to compromise of fetus and placing mother at risk for CVA or renal failure
Slide 10-

Cardiac During pregnancy, cardiac output increases up to 30% Can lead to CHF from preexisting
Slide 11-

Spontaneous Abortion Commonly called a miscarriage Occurs of its own accord Occur before the 12th week of pregnancy Many occur within 2 weeks after conception, being mistaken for menstrual cycle
Slide 12-

Criminal Abortion Attempt to destroy fetus by one whom is not licensed to do so Amateurs Without aseptic techniques Leads to other complications
Slide 13-

Therapeutic Abortion The pregnancy posed a threat to maternal well-being Judged to medically indicated
Slide 14-

Ectopic Pregnancy Pathophysiology Implantation of fertilized ovum outside of the uterus. Approximately 1:200 Most common site—fallopian tube Truly a medical emergency Causes extensive bleeding into the abdominal cavity and pelvis Predisposing factors— Previous pelvic infections Pelvic adhesions—previous abdominal surgery Tubal ligations IUD
Slide 15-

Assessment of ectopic pregnancy At risk for rapid development of shock Take VS frequently Abdominal—significant lower quadrant tenderness Avoid as much as possiblerupture of ectopic Bleeding can range from spotting  profuse
Slide 16-

Management Difficult to diagnose If suspected should care for as any shocky patient Emergent transport
Slide 17-

Abruptio Placenta Third trimester bleeding Premature separation of the placenta from the uterine wall. Partial or complete Complete often results in death of fetus Predisposing factors Preeclampsia Maternal HTN Multiparity Abdominal trauma Extremely short umbilical cord Vaginal blood loss is minimal due to blood collecting behind placenta
Slide 18-

Assessment Have constant, severe abdominal pain Feels like something is “tearing” Abdomen is very tender Bleeding will be dark in color PMH—abruptio placenta
Slide 19-

Management COMI Large bore IV’s Rapid transport
Slide 20-

Placenta Previa Attachment of the placenta that partially or completely covers the internal cervix Begins to bleed as the cervix thins out, spreading the placenta until it tears Precipitated by sexual intercourse or digital vaginal examination
Slide 21-

Assessment Usually multigravida Third trimester Most common—painless, bright red bleeding Uterus is soft Management— COMI High flow O2 Large bore IV’s Rapid transport

PIH Bp of 140/90 Early stage of disease process Bp is normally low so 130/80 maybe high
Slide 25-

Preeclampsia Characterized by: HTN Abnormal weight gain Edema Headache Protein in urine Epigastric pain Visual disturbances
Slide 26-

Eclampsia Characterized by the same as pre but includes seizures
Slide 27-

Supine Hypotensive Syndrome Occurs in the third trimester Marked decrease in blood flow to the heart due to increase mass in abdominal cavity Compresses on the inferior vena cava thus decreasing the blood flow back to the heart Assessment—be aware of signs of shock and verify previous problems with same Management—place in LLR, treat for shock if other signs of shock are present.
