describe the pelvic exam for vaginal bleeding
- Exam Set Up – cotton swabs, chux, speculum, wet prep, GC/Chlam
- Inspect perineum, vulva, urethra, and peri-anal region
- Cervix must be visualized to R/O polyps, ulcers, STD, mass
- May require use of swabs and/or suction to visualize structures
What labs should you get in someone who presents with vaginal bleeding
- Pregnancy test**
- Common tests: CBC, type and screen; chem-7 for renal function
- If pregnant: add quantitative BhCG (marker for how far along you are) and Rh
- If pregnant trauma: Kleihauer-Betke
- If concern for shock: 2 large bore IVs, fluids, Monitor, O2
Always assume ___ in any pregnant female with abdominal pain and or bleeding
an ectopic pregnancy
__% of ectopic pregnancies occur in the fallopian tube
95%
risk factors for ectopic pregnancy
- PID increases risk 6-7 fold- most common risk factor
- Previous ectopic
- IVF
- Tubal Ligation or surgery on the tube
- IUD
- Peri tubal Adhesions from other abdominal surgeries
- Induced Abortions
what is the classic triad for ectopic pregnancy
Vaginal Bleeding (80%) abdominal pain (90%) delayed menses (70%)
presentation for ectopic pregnancy
- History of amenorrhea between 4-12 weeks is common;15% report normal menses
- classic pain of rupture is LATERALIZED, sudden, sharp and severe. May c/o shoulder pain from diaphragm irritation
- Non rupture pain is due to tube distention
- Vaginal bleeding usually light
PE for ectopic pregnancy
- May present in shock if ruptured
- Peritonitis secondary to a hemoperitoneum
- Unruptured ectopic may have adnexal mass and tenderness on bimanual
- Pelvic exam findings may include: bluish cervix, enlarged uterus, blood in the vaginal vault, and cervical motion tenderness
- FHT usually not audible ( too early)
what is chadwick’s sign
bluish hue to cervix w/ pregnancy, from increased blood flow
*no clinical utility
Can hear FHTS using doppler US around __ weeks
12
describe the utility of a pregnancy test
Urine
95% sensitive/specific
+ 2 weeks after ovulation
May get false negative if dilute urine
Serum
+ 7-10 days after ovulation
describe the utility of beta quant “BhCG”
- In normal pregnancy, BhCG doubles approximately 48 hours
- Low HCG levels can suggest EP or “blighted ovum” (anembryonic pregnancy)
- High BhCG suggest GTD (molar pregnancy or choriocarcinoma), multiple pregnancy
- Always, miscalculation of dates may be considered
if BhCG is ____ IU/Ml, gestational sac should be visible on transvaginal US. (4.5-5 weeks)
-____ for a transabdominal US)
over 1500
over 6000
*if over 1500 and don’t see anything but + pregnancy test be worried about ectopic
If BhCG of ___ IU/MI, pregnancy may be too small to be seen on US and requires a repeat level in 48 hours
less than 1500
What is the utility of US w/ pregnancy
- US determines if an IUP is present
- may miss heterotopic pregnancy
A LIVING IUP may be definitively diagnosed when cardiac activity is seen in the uterine cavity (usually seen at ___ weeks)
6-7 weeks
how do you diagnose ectopic pregnancy
- definitive US (empty uterus AND extrauterine cardiac activity) OR
- direct visualization at laparoscopy
Caveat
A negative ultrasound does not rule out an EP just as a negative urine HCG does not rule out pregnancy
Moderate to large amount of free fluid can be suggestive of ___
EP
when is it important to recheck BhCG?
48-72 hrs
describe the management of ectopic preg.
- Consult OB/GYN
- Medical Treatment: Methotrexate (early)
- Indications: no fetal cardiac activity, BhCG less than 5000, less than 3-4 cm sized EP, and hemodynamically stable
- Abdominal pain 3-7 s/p injection is common
- Usually dosed IM; some need second dose - Surgical Management:
- Laparoscopy or laparotomy, +/-salpingectomy, particularly if later in pregnancy or unstable
Evaluation/Management of threatened miscarriage
- Patients can be discharged home with close follow-up
- Recheck Quantitative BhCG in 2-3 days if no confirmatory Ultrasound
- Pelvic rest (no sex)
- Return for increased bleeding, fever, pain, lightheadedness
*Return precautions- if saturating more than 1 pad per hour for 4-6 hours
describe Rh prophylaxis
-Administer RhoGAM to the gravid patient who is Rh (-) and is vaginally bleeding
Exception: when father is known Rh–
*When in doubt treat
1st trimester emergencies
- Ectopic Pregnancy
- Threatened or spontaneous Miscarriage
- Hyperemesis Gravidarum
- GTD – Gestational Trophoblastic Disease
neoplastic disease – can be noninvasive/ hydatidoform mole or choriocarcinoma/ invasive. Have abnormally large uterus and high BhCG
GTD – Gestational Trophoblastic Disease
with spontaneous miscarriages, bleeding occurs in __% of pregnancies, __% go on to a miscarriage
20%
50%
__% of spontaneous miscarriages occur prior to 12 weeks.
80%
*Cardiac activity on US reduces the chances of miscarriage to 5%
spontaneous miscarriages Usually due to
chromosomal abnormalities – nothing the patient did, or can do!
what are types of spontaneous miscarriages
Threatened - vaginal bleeding with a closed cervical os and benign PEX
Inevitable- vaginal bleeding with cervical dilation; cervical os is open
Incomplete- passage of only parts of products of conception (POC), usually occurs at 6-14 weeks; cervical os is open
Complete- passage of all POC and fetal tissue prior to 20 weeks. Os is closed.
Septic- evidence of infection during any stage of Abortion induced or spontaneous
describe the exam for a spontaneous miscarriage
- Consider use of yankower suction if significant bleeding. You must visualize the cervix
- Material protruding from the os should be removed carefully as it may represent a cervical ectopic pregnancy
**All POC, clot or other unidentifiable material should be sent for pathology
what dx tests do you get with spontaneous evaluation
US is used to R/O ectopic pregnancy, as a prognostic tool for fetal viability, and to diagnose retained POC
