GU Flashcards
Risk factors for ectopic pregnancy?
Hx PID Hx ectopic pregnancy Tubal surgery including BTL Previous pelvic or abdominal surgery Tubal pathology In utero DES exposure IUD Smoking Infertility/infertility Rx
Classic presentation of ectopic pregnancy?
Abdominal pain, delayed menses, vaginal bleeding
Remember that paradoxic bradycardia can occur in ectopic pregnancy, so vital signs should not be reassuring.
Initial actions and primary survey in ectopic pregnancy?
ABCs Pregnancy test Monitor, 2 large bore IVs CBC, T&S, quantitative beta-hCG Narcotic analgesia Immediate bolus of NS if ill-appearing, severe pain, or abnormal vitals Consider O- transfusion if hypotension FAST exam if concern for rupture Bedside pelvic US
Call Ob-Gyn immediately if +FAST with +pregnancy test
Diagnostic work-up in stable patients with possible ectopic pregnancy?
TVUS to evaluate for the presence or absence of an IUP. If visualized, concurrent ectopic pregnancy is statistically unlikely unless the patient has received fertility treatments.
Beta-hCG
Signs of IUP on TVUS?
Earliest - double decidual sac sign (4.5-5 weeks after LMP) Yolk sac (5-6 weeks) Fetal pole and embryonic cardiac activity (6-7 weeks)
What has a 100% predictive value for IUP?
Yolk sac
Discuss interpretation of quantitative beta-hCG levels in early pregnancy.
Produced by trophoblasts, doubles Q48-72 hours in T1.
Discriminatory zone for when an IUP should be visible on TVUS: 1500-2000 mIU/mL
Ectopic is highly likely if level >1500 with absence of IUP on TVUS
If ectopic pregnancy is not ruled out in the ED, what can be done?
Outpatient OBG - serial US with serial serum quant beta-hCG levels. Rise in level slower than expected is highly suspicious.
Rx ectopic pregnancy?
If unstable - surgery
Fluid and blood resuscitation, pain management, OBG consultation
RhoGAM if Rh-negative
MTX (medical management) - can give 2 doses if 1st dose fails
Contraindications to MTX in ectopic pregnancy?
Hemodynamic instability, inability to follow-up, breastfeeding, immunodeficiency, renal/liver/pulmonary disease, PUD, blood dyscrasias
Initial actions and primary survey in patients with suspected PID?
Pelvic exam Pregnancy test (if pregnant, consider other causes of pelvic pain, as PID is less likely in pregnancy)
Classic presentation of PID?
Bilateral lower abdominal pain
Purulent vaginal discharge (vaginal bleeding less frequently)
Symptoms begin shortly after the start of the menstrual cycle when there are fewer defenses by the mucosal barrier to ascending infections
N/V, general malaise
Hx STDs, multiple sexual partners, IUD use, adolescence, sexual intercourse at an early age, recent instrumentation of the uterine cavity
Bilateral adnexal tenderness, purulent cervical discharge, cervical motion, uterine, lower abdominal tenderness
What physical exam finding suggests tubo-ovarian abscess?
Unilateral adnexal tenderness or fullness with PID symptoms
What physical exam finding suggests Fitz-Hugh-Curtis?
RUQ tenderness with PID symptoms
Dx testing for PID?
UA
CBC with diff
LFTs (if FHC is suspected)
PCR or DNA testing for CG (more sensitive than culture, can be run on cervical secretions or urine, more rapid)
Pelvic US if TOA is suspected or if diagnosis is unclear (r/o other diseases)
CT (not preferred, often ordered if appendicitis or other intraabdominal pathology is suspected)
Diagnose PID?
Negative pregnancy test + elevated WBC with fever, bilateral adnexal tenderness, and mucopurulent cervical discharge -> certain diagnosis
PCR positive for G/C in appropriate clinical setting
