OBGYN Emergencies Flashcards
APPROACH TO VAGINAL BLEEDING IN THE ER
What is the first thing we assess?
Assess the hemodynamic state of the patient
APPROACH TO VAGINAL BLEEDING IN THE ER
Assess the hemodynamic state of the patient:
If not hemodynamically stable, proceed how? 3
- begin appropriate measures for fluid resuscitation and stabilization
- Immediately determine if the patient is pregnant
- Emergently refer to OB/GYN service for possible OR intervention
APPROACH TO VAGINAL BLEEDING IN THE ER
Assess the hemodynamic state of the patient:
If hemodynamically stable?
If hemodynamically stable:
- Determine if the patient is pregnant
- Determine the amount and length of time of vaginal bleeding
- Do a complete pelvic exam (UNLESS- PLacenta previa! Have to do an US if they are pregnant in the third trimester
APPROACH TO VAGINAL BLEEDING–HX

APPROACH TO VAGINAL BLEEDING–TESTS
6
- Qualitative and sometimes quantitative hCG test:
- CBC
- Type and cross if significant bleeding
- Type and screen if not immediately needing blood transfusion
- Coag tests if coagulopathy suspected
- STIs tests if suspected infection (PID)
Qualitative and sometimes quantitative hCG test:

- TVUS can determine an intrauterine pregnancy at hCG levels of _______ mIU/mL or above?
- less than 1000 mIU/mL
2. 1500
APPROACH TO VAGINAL BLEEDING CONT.
Differential Diagnosis—Based on patient age:
Prepubertal patient?
- Vulvovaginitis
- Foreign body
- Trauma
- Urethral prolapse
- Sexual abuse
- Hormone secreting tumor
What would be evidence for the following in a prepubertal pt with vaginal bleeding:
- Vulvovaginitis?
- Foreign body?
- Trauma?
- Urethral prolapse?
- Sexual abuse?
- —bloody vaginal discharge/pruritis
- —bloody vaginal discharge/foul smelling
- —varied presentation—history is important
- —can visualize on exam
- —blood from sexual trauma, may have bruising, c/o pain–MUST have careful approach and may involve collecting evidence
APPROACH TO VAGINAL BLEEDING
Premenopausal nonpregnant pt?
7
- Ruptured ovarian cyst**
- Ovarian torsion**
- PID—decision to treat as outpatient or inpatient
- Dysfunctional uterine bleeding:
- Uterine leiomyoma
- Uterine polyp
- Genital trauma secondary to sexual abuse
Dysfunctional uterine bleeding in a premenopausal nonpregnant pt may be caused by?
- May be caused by endometrial cancer in a patient as young as 35YO
Treatment for DUB
APPROACH TO VAGINAL BLEEDING
Peri-/Post-Menopausal patient:
5
- Primary concern is endometrial cancer
- Anti-coagulant medication
- Hormonal therapy
- Other medications
- Coagulopathy
Peri-/Post-Menopausal patient:
Primary concern is endometrial cancer: How should we proceed with management? 2
- DO NOT start on OCPs!
2. Refer for appropriate evaluation and diagnosis
APPROACH TO THE PREGNANT PATIENT: Vaginal Bleeding
- First trimester? 3
- Second and third trimester? 3
- Early postpartum?
- First trimester:
- Bleeding from implantation
- Threatened, impending or incomplete miscarriage
- Ectopic pregnancy: abdominal pain, amenorrhea, vaginal bleeding** - Second and third trimesters:
- Placenta previa
- Placental abruption
- Genital trauma secondary to abuse (?) - Early post-partum—post-partum hemorrhage
GENERAL TREATMENT CONSIDERATIONS
Remember the ABC’s!
You have 2 (or more) patients: stabilize mom first and then the baby(s)
- REMEMBER general measures? 3
- With vaginal bleed: Early signs? 2 Late signs? 3
- Women who are Rh neg need _______ after any bleeding episode!!!
Remember the ABC’s!
You have 2 (or more) patients: stabilize mom first and then the baby(s)
- REMEMBER general measures:
- O2
- lateral displacement of the -uterus
- IV fluids
2. With vaginal bleed: Early signs of hemodynamic compromise are -tachycardia -tachypnea Late: -hypotension, -weak pulse -oliguria
- Rhogam
VAGINAL BLEEDING IN EARLY PREGNANCY
Etiologies? 4
Evaluation? 4
- Etiologies
- Ectopic pregnancy
- Threatened, impending, incomplete miscarriage
- Physiologic (i.e. Implantation of the pregnancy
- Cervical, vaginal or uterine pathology - Evaluation
- History: amount of bleeding, passed clots or tissue, pain?
- Physical: hemodynamic status
- Ultrasound
- Labs: hCG, CBC, UA, cultures as indicated
MISCARRIAGE
1. Presentation of a threatened miscarriage? 5
- Inevitable miscarriage? 5
- Threatened Miscarriage
- No cramping
- Closed cervix
- US: + fetal cardiac activity
- 90-96% will go on to term
- Expectant management - Inevitable Miscarriage
- + cramping
- Increased bleeding
- US: – cardiac activity or fetal demise
- Open cervical os
- Management expectant or surgical
INCOMPLETE MISCARRIAGE
- Definition?
- Symptoms? 2
- On exam? 2
- US?
- Management?
- Definition: the fetus is passed, but placental tissue is retained
- SYMPTOMS:
- Moderate to severe cramping
- Bleeding—bleeding can be severe enough to cause hypovolemic shock - On exam:
- The cervical os is open & gestational tissue may be present
- Uterus feels “boggy” on palpation - US shows tissue in uterus
- Surgery is usually necessary to remove retained tissue
ECTOPIC PREGNANCY
- Incidence?
- Hx: look for risk factors?
- Presentation? 4
- Incidence: 1 in every 100 pregnancies in the United States
- Hx: look for risk factors:
- Previous ectopic pregnancy
- Tubal surgery
- History of PID
- Women undergoing treatment for infertility - Presentation:
- Abdominal pain(most common symptom)
- Vaginal bleeding
- Amenorrhea
- Hypovolemic shock
Differential Diagnosis
7
- Urinary tract infection or kidney stones
- Appendicitis, diverticulitis
- Ovarian torsion, neoplasm, ruptured cyst
- Endometriosis, PID, endometritis
- Implantation of the pregnancy
- Threatened, inevitable or incomplete miscarriage
- Cervical, vaginal or uterine pathology
ECTOPIC PREGNANCY
1. PE? 4
- Transvaginal US? 3
- Physical Exam:
- Check hemodynamic status
- May reveal abdominal or pelvic tenderness
- May find adnexal mass
- May be unremarkable - Transvaginal US:
- Most helpful to determine if intrauterine pregnancy (IUP) is present
- An IUP should be seen if serum hCG > 2000mlU/ml
- If it’s an ectopic pregnancy it’s usually seen in a fallopian tube (97%)
- If the TVS is inconclusive and the patient is stable serial quantitative hCG’s are followed
MORE ON ECTOPIC PREGNANCY!
- If the patient presents with what she is considered to have a ruptured ectopic pregnancy & needs immediate surgical intervention? 2
- If the patient is stable then treatment with what can be considered with an OB consult?
- (has a +hCG)
- is hemodynamically unstable
- methotrexate
