  1. Obstetrics/Gynecology Emergency Medical Technician - Basic

  2. Female Reproductive System Uterus Cervix Urinary Bladder Vagina Rectum

  3. Female Reproductive System Uterus Ovary Cervix Fallopian tube Vagina

  4. OB/Gyn Assessment • History • When was your last normal menstrual period (LNMP)? • Abdominal pain? (location/quality) • Vaginal bleeding/discharge?

  5. OB/Gyn Assessment • History • Is there a possibility you might be pregnant? • Missed period? • N/V • Increased urinary frequency • Breast enlargement • Vaginal discharge

  6. OB/Gyn Assessment • History • If pregnant: • Para = # of live births • Gravida = # of pregnancies • -3 /+ 7 to estimate due date Subtract 3 from the month of the LNMP Add 7 to the date of the LNMP LNMP - 12/9/98 Due date - 9/16/99

  7. OB/Gyn Assessment • Vital signs • Hypertension • Hypotension • Tilt test if blood loss is suspected • Focused exam • Edema (particularly of face, hands)

  8. Gyn Emergencies

  9. Ectopic Pregnancy • Zygote implants in location other than uterine cavity • 95% are in Fallopian tube (tubal ectopic) • Life threatening!

  10. Ectopic Pregnancy • Signs and Symptoms • Missed period, other signs/symptoms of early pregnancy • Light vaginal bleed (spotting) 6-8 weeks after LNMP • Abdominal pain, may radiate to shoulder • Positive “tilt” test • Other signs/symptoms of hypovolemic shock

  11. Ectopic Pregnancy • Signs and Symptoms • Abdominal pain may be absent • Some patients may NOT miss period • Some patients may have NEGATIVE pregnancy tests

  12. Ectopic Pregnancy Lower abdominal pain or unexplained hypovolemic shock in a woman of child-bearing age equals Ectopic Pregnancy Until Proven Otherwise

  13. Ectopic Pregnancy • Management • 100% O2 • Supportive care for hypovolemic shock • Transport immediately

  14. Pelvic Inflammatory Disease • Acute or chronic infection • Involves Fallopian tubes, ovaries, uterus, peritoneum • Most commonly caused by gonorrhea • Staph, strep, coliform bacteria also cause infections

  15. Pelvic Inflammatory Disease • Signs and Symptoms • Lower abdominal pain • Gradual onset over 2-3 days, beginning 1-2 weeks after last period • Fever, chills • Nausea, vomiting • Yellow-green vaginal discharge • Walks bent forward, holding abdomen

  16. Pelvic Inflammatory Disease • Management • High concentration O2 • Transport

  17. Spontaneous Abortion • “Miscarriage” • Pregnancy terminates before 20th week • Usually occurs in first trimester (first three months)

  18. Spontaneous Abortion • Signs and Symptoms • Vaginal bleeding • Cramping lower abdominal pain or pain in back • Passage of fetal tissue

  19. Spontaneous Abortion • Complications • Incomplete abortion • Hypovolemia • Infection, leading to sepsis

  20. Spontaneous Abortion • Management • High concentration O2 • Shock position • Transport any tissue to hospital • Provide emotional support

  21. Pre-eclampsia • Acute hypertension after 24th week of gestation • 5-7% of pregnancies • Most often in first pregnancies • Other risk factors include young mothers, no prenatal care, multiple gestation, lower socioeconomic status

  22. Pre-eclampsia • Triad • Hypertension • Proteinuria • Edema

  23. Pre-eclampsia • Sign and Symptoms • Hypertension • Systolic > 140 mm Hg • Diastolic > 90mm Hg • Or either reading > 30 mmHg above patient’s normal BP • Edema (particularly of hands, face) present early in day

  24. Pre-eclampsia • Signs and Symptoms • Rapid weight gain • >3lbs/wk in 2nd trimester • >1lb/wk in 3rd trimester • Decreased urine output • Headache, blurred vision • Nausea, vomiting • Epigastric pain • Pulmonary edema

  25. Pre-eclampsia • Complications • Eclampsia • Premature separation of placenta • Cerebral hemorrhage • Retinal damage • Pulmonary edema • Lower birth weight infants

  26. Pre-eclampsia • Management • 100% O2 • Left lateral recumbent position • Avoid excessive stimulation • Reduce light in patient compartment • Avoid use of emergency lights, sirens

  27. Eclampsia • Gravest form of pregnancy-induced hypertension • Occurs in less than 1% of pregnancies

  28. Eclampsia • Signs and Symptoms • Signs, symptoms of pre-eclampsia plus: • Grand mal seizures • Coma

  29. Eclampsia • Complications • Same as pre-eclampsia • Maternal mortality rate: 10% • Fetal mortality rate: 25%

  30. Eclampsia • Management • 100% O2; assist ventilations, as needed • Left lateral recumbent position • Reduce light • Manage like any major motor seizure • Emergency transport • Consider ALS intercept for anticonvulsant medication administration

  31. Eclampsia • Assess every pregnant patient for • Increased BP • Edema • Take all reports of seizures in pregnant females seriously

  32. Abruptio Placentae • Premature separation of placenta from uterus • High risk groups • Older pregnant patients • Hypertensives • Multigravidas

  33. Abruptio Placentae • Signs and Symptoms • Mild to moderate vaginal bleeding • Continuous, knife-like abdominal pain • Rigid, tender uterus • Signs, symptoms of hypovolemia

  34. Abruptio Placentae Third Trimester Abdominal Pain equals Abruptio Placentae until proven otherwise

  35. Abruptio Placentae Hypovolemic shock out of proportion to visible bleeding equals Abruptio Placentae until proven otherwise

  36. Abruptio Placentae • Management • 100% O2 • Left lateral recumbent position • Supportive care for hypovolemic shock • Rapid transport

  37. Placenta Previa • Implantation of placenta over cervical opening

  38. Placenta Previa • Signs and Symptoms • Painless, bright-red vaginal bleeding • Soft, non-tender uterus • Signs and symptoms of hypovolemia

  39. Placenta Previa • Management • 100% O2 • Left lateral recumbent position • Supportive care for hypovolemic shock • Never perform a vaginal exam on a pt in the 3rd trimester with vaginal bleeding

  40. Placenta Previa A vaginal exam should NEVER be performed on a patient in the 3rd trimester with vaginal bleeding

  41. Uterine Rupture • Causes • Blunt trauma to pregnant uterus • Prolonged labor against an obstruction • Labor against weakened uterine wall • Old Cesarian section scar • Grand multiparous patients

  42. Uterine Rupture • Signs and Symptoms • “Tearing” abdominal pain • Severe hypovolemic shock • Firm, rigid abdomen • Possible palpation of fetal parts through abdominal wall • Vaginal bleeding may or may not be present

  43. Uterine Rupture • Management • 100% O2 • Anticipate shock • ALS/helicopter intercept

  44. Emergency Childbirth

  45. Developing Fetus Fetus Placenta Umbilical cord Amniotic Sac “Bag of waters”

  46. Labor • 1st stage: Onset of contractions to dilation of cervix • 2nd stage: Complete dilation of cervix to delivery of baby • 3rd stage: Delivery of baby to delivery of placenta

  47. Signs of Imminent Delivery • Crowning • Rupture of Amniotic Sac • Need to bear down • Sensation of needing to move bowels • Contractions • 1 to 2 minutes apart • Regular • Lasting 45 to 60 seconds

  48. Delivery • Place gloved hand on presenting part to prevent “explosive” delivery • On delivery of head, suction mouth then nose

  49. Delivery • Gently guide baby’s head down to deliver upper shoulder • Gently guide baby’s head up to deliver lower shoulder • Gently assist with delivery of rest of baby; Do NOT pull • Note time of delivery of baby

  50. Delivery • Control slippery baby during delivery • Support head, shoulders, feet • Keep head lower then feet to facilitate drainage of secretions from mouth • Dry baby • Keep baby warm
