General Intro / Main Questions
18 yo F G0P0 presents with sudden onset vaginal bleeding after passing multiple large clots and three syncopal events on the toilet. She has a history of polycystic ovarian syndrome and depression. Home medications include fluoxetine and metformin. She had a normal menstrual period 2 weeks ago. Initial vital signs include blood pressure 101/52 and pulse 95. She is pale, shivering, and continues to pass clots intermittently. Urine pregnancy is negative, hemocue (point of care hemoglobin) is 9.9.
An hour later, her blood pressure is 75/30 and pulse is 97. Hemocue is 5.4. Your ob-gyn consultant is in an emergency C-section. What is the differential diagnosis and how are you going to stabilize this healthy 18 year-old female who is bleeding out in front of you?
PALM-COEIN for etiologies of vaginal bleeding introduced in 2011 by FIGO (International Federation of Gynecology and Obstetrics) and adopted by ACOG (American College of Obstetricians and Gynecologists):
In addition, terminology has been simplified: menorrhagia is now heavy menstrual bleeding and metrorrhagia is intermenstrual bleeding.
- Anovulatory Bleeding: Irregular periods and unpredictable bleeding.
- Ovulatory Bleeding: Heavy and prolonged menstrual periods.
|12-18y||Immaturity of hypothalamic-pituitary-ovarian axis leading to persistent anovulation. Other causes include pelvic infection and coagulopathy (up to 20% of girls presenting to ED with vaginal bleeding may have von Willebrand disease).|
|19-39y||Structural lesions such as polyps and fibroids. Fibroid is most common pelvic tumor; 20-50% incidence in reproductive age women with incidence increasing with age. Bleeding occurs from disruption of submucosal blood supply surrounding fibroid, often during menstruation. PCOS should be considered in pts with anovulatory bleeding and signs of androgen excess: acne, hirsutism, alopecia, and obesity.|
|>40y||Endometrial atrophy is most common cause, however 10% diagnosed with endometrial carcinoma. Etiology is cancer until proven otherwise.|
Vaginal bleeding treatment in stable patients
- Workup includes pregnancy test and CBC. Coagulation studies if patient has symptoms of easy bruising or bleeding, or if taking anticoagulant(s). Imaging of choice is pelvic ultrasound looking for structural causes such as polyps, fibroids, AV malformation, and endometrial thickness to assess for carcinoma.
- Anovulatory bleeding is most effectively treated with hormonal treatment. Ovulatory bleeding is treated with non-hormonal treatments. Please see figure 1 for discussion of treatments.
|Combination OCP||1 pill TID x 7 days||> 35 yo F who smokes,Hx of DVT, PE, breast cancer, liver disease, thromboembolic disorder, ischemic heart disease, CVA, uncontrolled HTN||Cochrane (2009): Not enough evidence to assess|
|Progestin-only||20 mg TID x 7 daysor10 mg Qd x 10 days||Hx of DVT, PE, liver dz, or breast cancer|
|NSAIDs||Ibuprofen 200-400 mg TID x 5 daysorNaproxen 500 mg then 250 mg TID x 5 days||Advanced renal disease. Avoid in pts with known or suspected bleeding disorders||Cochrane review of 18 small RCTs shows more effective than placebo|
|Tranexamic acid||1.3 g TID for up to 5 days||Active intravascular clotting or SAH||Cochrane: 4 small RCTs, superior to placebo, NSAIDs, and oral progestin|
- In pt with vWD, use desmopressin with tranexamic acid in the absence of massive hemorrhage.
- If on anticoagulant therapy, administer prothrombin complex concentrate (PCC) rather than FFP in conjunction with vitamin K.
- Platelet transfusion if < 50k.
Vaginal bleeding treatment in unstable patients
Aggressive fluid resuscitation and transfusion of blood products if needed.
- Estrogen promotes rapid endometrial growth, covering areas that are denuded and bleeding.
- Treat with 25 mg IV q4-6h until bleeding stops. Contraindications are active or past thromboembolic disease, breast cancer, or liver disease. Supporting data is a small randomized controlled trial in 1982 of 34 pts which showed cessation of bleeding in 72% of treatment group vs 38% in control group.
- Intrauterine tamponade with 26 Fr foley infused with 30 mL of saline or balloon for postpartum hemorrhage e.g. Bakri balloon.
- Tamponade of os with pediatric foley.
- Vaginal tamponade with gauze, using long strips for easier removal.
- Dilation and curettage (D+C): Surgical treatment of choice in patients with acute bleeding resulting in hypovolemia. Maintains fertility. High need for recurrent procedures.
- Endometrial ablation
- Uterine artery ablation
Bottom Line/Pearls & Pitfalls
- To estimate volume of blood; clenched fist is about 500 mL / 50 cm diameter floor spill is also about 500 mL.
- PALM-COEIN separates differential for vaginal bleeding into structural and non-structural causes.
- In unstable patient: resuscitate with fluid / blood and conjugated estrogen IV. Consider tamponade. Consult ob-gyn early for possible surgical intervention.
- D+C is only surgical option which maintains fertility. However if etiology is AV malformation, D+C can worsen bleeding.
