Obstetrics and Gynecology Emergencies – Dr. Marques

Normal Vaginal Delivery Key Steps

  • Support the perineum to prevent tearing with delivery of the anterior shoulder
  • Upon delivery of the anterior shoulder, provide upward pressure to deliver the newborn
  • Pull only gentle traction when delivering the placenta, to avoid uterine inversion

Post-Partum Hemorrhage

  • Palpate the uterus to feel for inversion or retained products
  • Provide tone by providing suprapubic pressure with an external hand and uterine pressure with an intravaginal hand
  • Oxytocin can be given IM or IV to treat uterine atony

Shoulder Dystocia

  • Leg hyperflexion and abduction at the hips along with suprapubic pressure (McRobert’s Maneuver) can be done if the anterior shoulder cannot be delivered

Breech Delivery

  • This happens in 3-4% of all deliveries
  • Do not pull traction at any time, as this can lead to entrapment in a cervix that is not dilated
  • A pressure against the popliteal fossa can help flex the leg and deliver each leg

Oral Boards: Sepsis Due to Spontaneous Bacterial Peritonitis – Hugh, Shoff, MD

  • The CMS Core Measures (SEP-1) provide quality measures for providers to follow in sepsis
  • Severe Sepsis is defined as Lactate >2 or organ dysfunction
  • Septic Shock is defined as severe sepsis with hypoperfusion despite fluid resuscitation or lactate>4
  • Within 3 hours of presentation, obtain a lactate, blood cultures prior to broad spectrum antibiotics, and 30cc/kg fluid resuscitation
  • Within 6 hours, lactate must be repeated if >2

CCU Follow-Up – Phil Giddings, MD

Myocardial bridging- coronary arteries travel deep into myocardium as opposed to laying upon the muscle

The vessels are occluded but when there is demand ischemia it can look like a STEMI

Myocardial bridging is fairly common in the general population, but usually isn’t symptomatic or pathologic.

If it is symptomatic- you could do Ca2+ channel blockers, beta blockers, and even myotomy or CABG if you’re feeling wild.

Urology Review- Isaac Shaw, MD

Priapism-

  • Normal tumescence- veins constrict so the corpus cavernosum engorges because blood flows in
  • Ischemic= low flow, less venous outflow, rigid, painful
  • Nonsichemic= high flow, more arterial inflow, half rigid
  • (Distinguish w/ a blood gas)
  • Treatment
  • anesthetize by blocking the dorsal nerve of the penis (2 & 10 o’clock) w/o epi
  • then aspirate at 3 or 9 o’clock from the corpus cavernosum
  • Use a phenylephrine stick from Room 9, 100mcg-500mcg Q1-5min

Fournier’s Gangrene

  • polymicrobial
  • assoc w/ DM
  • 22-40% mortality
  • empiric + clindamycin (clinda first because it’s addressing the toxins)

consult surgery before imaging

Paraphimosis

  • foreskin trapped proximal to glans so the tip can get ischemic
  • Treatment: manually reduce, dextrose, lube, may have to incise the dorsal foreskin

Phimosis

  • foreskin can’t be retracted over the glans 2/2 inflammation
  • Treatment in ED: topical steroids with urology follow-up

Urinary Retention

  • often have hesitancy, nocturia, frequency, urgency
  • >200cc PVR
  • d/c w/ Foley à Uro will keep that in for 2 weeks prior to void trial

Renal Stones

  • remember that 10-15% don’t have hematuria
  • CT w/o contrast is still the standard for diagnosis, but some emergent literature exists that US alone is sufficient in young, healthy patients
  • if <5mm, 90% pass; but if >8mm, 5% pass
  • admit for intractable vomiting, pain, urinary extravasation, infection & obstruction

Balanitis

  • Candida on the glans
  • Associated with DM or uncircumcised

Torsion

  • twisted around the spermatic cord
  • if actively torsed, you will NOT have a cremasteric reflex
  • ultrasound 88-100% sensitive because they can torse and untorse
  • consult before imaging

Breaking Bad NewsFrank Woggon, PhD

  • insensitive truth telling can have similar effects as lying
  • goals include gathering info, provide info, support patient, strategy for care
  • keep it simple, no jargon, talk slow, repeat PRN, use neutral language, be honest, allow emotions, consider cultural differences
  • “compassion is the willingness to let yourself be affected by the life and suffering of others”

SPIKES

  • Setting- privacy, sit down, eye contact, turn off pager
  • Perception- don’t combat denial at first, interpret first
  • Invitation- ask how much they want to know first
  • Knowledge- “what I’m about to say is not good,” be direct but not blunt, use their language
  • Empathize- ok to validate the emotions, silence is ok
  • Strategy & Summary- what comes next

GRIEV_ING Protocol

  • Gather the family
  • Resources- call for support
  • Identify yourself & staff, those in the room
  • Educate the family about what happened
  • Verify that the patient died by using that word
  • SPACE- silence is ok, let them have their gut reaction
  • Inquire whether they have questions
  • Nuts & bolts- organ donation, funeral arrangements, personal belongings, etc.
  • Give contact info for f/u questions

STEMI Mimicks – Frank Shary, MD

OMI= occlusive MI

  • V2 & V3 2mm elev = STEMI; Everywhere else 1mm
  • Wellens: biphasic T wave, they recently had an OMI, symptoms may have gotten somewhat better by the time of the EKG, they need a cath
    • Deep T Wellens- deep and wide
  • LV aneurysm- deep Q wave w/ biphasic T wave, static
  • Sgarbossa criteria- OMI in the setting of LBBB and/or paced rhythm
    • look at vector of QRS and vector of ST segment
    • concordant elevation or depression greater than 1mm
    • discordant greater than 5mm
  • Hyperacute T waves- early into the ischemia, before ST elevation, cath soon because you have potential to save more myocardium, large area under the curve especially in proportion to the QRS complex
    • L circumflex is the vessel most likely to be silent
  • aVR- if it’s the only lead elevated and everywhere else is diffusely depressed, you might have diffuse subendocardial ischemia
    • could be bad triple vessel disease

Managing the Bleeding Patient Without Blood Products – Chase, PharmD

There are 6 Jehovah’s Witness churches in Louisville

  • Plasma Derivatives are technically not Blood products… so whether or not a patient wants that is up to the individual
  • albumin, clotting factors, PCC, Immunoglobulins (including Rhogam and vaccines)
  • equine Ig and Crofab could also be iffy
  • ECMO, cardiopulmonary bypass, dialysis are allowed generally

Source Control

  • bone wax/putty- use in NES and long bone fx, high infection rate though
  • oxidized regenerated cellulose- ex. Surgicell, promotes rebuilding of proteins to heal & achieve hemostasis, like a mesh
  • gelatin matrix- ex. Floseal, more like a gel
  • there is a powder too but it’s $$$ and causes microemboli so don’t use
  • thombin- apply w/ 4×4’s
  • TXA- derivative of lysine THIS IS NOT A PLASMA DERIVATIVE SO THEY SHOULD BE OK WITH IT, 1g over 10min à another 1g over 8-10 hours
  • have a lower threshold to give TXA since there is a decrease in mortality, even if you wouldn’t have given TXA to a non-Jehovah’s witness

Usable Therapies:

  • Cell Saver
    • blood is collected, washed, centrifuged, returned to patient
    • example indications: AAA, TKA, THA, cardiac surgeries
  • Vitamin K
  • PCC- most efficacious
    • 4 factor is better than 3 factor, but if you try to give 3 factor and then just add Factor VII a la carte, more thromboembolic events
  • FFP- prep time is longer, tonzo volume
  • Adnexanet Alpha- new antidote for rivaroxaban and apixaban, we don’t have that
  • Novo7- directly activates Factor VIII, black box warning for thromboembolic events, no difference in mortality but there was a reduction in transfusions
  • Dabigatran reversal- idarucizumab, dialysis, charcoal
  • Antiplatelet reversal- ASA and Plavix are irreversible, but ticagrelor is reversible
    • DDAVP- indicated for DI, von Willebrand disease, uremic bleeding (renal failure), nocturnal enuresis
    • 0.4mcg/kg over 10min

Pediatric Environmental Emergencies- Dr. Said

Drowning

  • fresh or salt water doesn’t matter, you’re ruining your surfactant
  • if you are anoxic you get brain damage in 4-6min, irreversible
  • cold temp is only helpful if it happens really quickly
  • outcomes depend on initial resuscitation, degree of pulmonary damage, time submerged
  • poor prognosis- coma, apnea, submersion >9min
  • can try vapotherm for positive pressure, albuterol can treat bronchospasm
  • steroids don’t help
  • goal warming 32C
  • if asymptomatic, obs for 8 hours! Oy vey
  • admit if prolonged submersion, respiratory or neuro symptoms, abnormal CXR

Electrical Injuries

  • lightning strikes carry 30% mortality risk, it causes asystole
  • doesn’t cause renal failure or burns/compartment syndrome
  • thicker tissue less damaged
  • tissue between entry and exit wounds could be more damaged interiorly than it appears
  • AC worse than DC because AC at low voltage causes tetany so you’re holding on longer
  • we use DC for defib, countershock, pacing but you get thrown off
  • oral electrical injury – monitor for progressive edema
  • could have delayed bleeding from labial artery

EMTALA- Melissa Platt, MD

  • in court, all are case-by-case
  • we have to provide a medical screening exam and treat and stabilize an emergency medical condition
  • transferring physician assumes the risk if the patient crumps en route to accepting hospital

Interesting Ultrasound

A late 20s F G4P3003 at approximately 6 weeks gestation by LMP presents with a chief complaint of vaginal bleeding. A few hours PTA, patient states she felt a “gush of blood” with some mild abdominal cramping. VSS. On exam, noted to have a moderate amount of vaginal bleeding per the os. On our bedside ultrasound we note what appears to be a viable IUP with cardiac activity.  However, the uterus appears septate, with half containing the IUP and the other half more hyperechoic/solid in nature. We were concerned for a possible subchorionic hemorrhage and consulted OB/GYN. Our bedside US image is below:

BS US

OB came down with their Cadillac ultrasound and confirmed our findings.  For comparison, here is their much clearer image:

OB US

For this patient, with this large of a subchorionic bleed, the likelihood of her carrying this pregnancy to term was low. They planned to have her follow up in clinic for a repeat ultrasound in 2 weeks to reassess viability. Per our OB colleagues, other things on the differential included a fibroid. However, as this patient had 3 very healthy and rambunctious boys at the bedside with her, OB commented that a fibroid that large would likely have resulted in infertility.

And from UptoDate:

“A subchorionic hemorrhage or hematoma is a risk factor for spontaneous abortion, particularly when it amounts to 25 percent or more of the volume of the gestational sac. A meta-analysis of seven comparative studies found that women having a subchorionic hematoma had a significantly increased risk of spontaneous abortion, compared to women without such findings (18 versus 9 percent; OR 2.18, 95% CI 1.29–3.68). The findings also are associated with an increased risk of placental abruption (4 versus 1 percent; OR 5.71, 95% CI 3.91–8.33) and preterm premature rupture of membranes (4 versus 2 percent; OR 1.64, 95% CI 1.22–2.21). The increased risks of preterm labor and stillbirth appeared to be dependent upon the presence of vaginal bleeding.

Pregnancy outcome associated with subchorionic hematoma also relates to location, with worse outcomes observed for retroplacental hematomas, compared to marginal hematomas. The location, rather than the size, of a subchorionic hematoma may be the most important predictor of pregnancy outcome. Evidence relating to the size of the hematoma and the risk of adverse outcomes is inconclusive.

The only management option for subchorionic hematoma is expectant. There is insufficient evidence regarding whether bed rest decreases the risk of pregnancy loss when a subchorionic hematoma is present. Some clinicians repeat an ultrasound in one to two weeks to confirm fetal viability and assess any change in size of the hematoma, primarily to provide reassurance to the patient. A subchorionic hematoma is not an indication to conduct a diagnostic evaluation for an acquired or inherited thrombophilia.”

A large red herring

The patient is a 20s y/o AAF, multip, last normal period 3 weeks ago (definite date), who presented to another facility with spotting and occasional moderate bleeding for about a week with 4 days of crampy pelvic pain, worse on the left than the right.  There, she was diagnosed with trichomonas and treated empirically for gonorrhea and chlamydia.  She had a positive pregnancy test and reportedly had transabdominal and transvaginal ultrasounds.  She stated they told her she definitely had a pregnancy in her left tube.  She was given instructions to see her regular doctor in 48 hours for a repeat evaluation and discharged.

It is at this point that the big red flashing lights in my head go off and I think to myself “Wait, WHAT?  Someone DISCHARGED a confirmed ectopic?  No way.  Maybe they said it was a possibility and she misinterpreted.”  Whatever the sequence of events, all that mattered was that I get the records and do an ultrasound myself.

Her records came in from the other ED after a couple of attempts (as per usual).  A few things that I learned from her records:
1. she was indeed told that she had an ectopic and that she should see her regular doctor or OB in 48 hours.
2. she did get treated for STDs.
3. sure, she had an ultrasound, but there wasn’t any interpretation available unless I called and had them hold the phone up to the speaker (didn’t have time to do this).
4. my dislike for paper charts is warranted when I can’t read what someone says about my patient.

Initial vitals normal with a HR 100, BP 118/78
She was tender in the LLQ and suprapubic areas without peritoneal signs.  Cervix was closed, she had a small to moderate amount of dark blood in the vaginal vault, and had uterine and left adnexal tenderness on bimanual exam.

I started fluids, gave her some meds for her nausea, and put in all the usual orders.

Labs:
-WBC 13.8 (88% Neut)
-Hb 9.6
-CMP unremarkable
-U/A positive for blood/protein/ketones but micro negative
-Quant 12000+
-Swabs + for trich

And then came the ultrasound:

transverse view, abdominal probe

transverse view, abdominal probe

longitudinal view, abdominal probe

longitudinal view, abdominal probe

A few things about this caused even more red light flashing: first, how could a gestational sac be THAT SIZE in someone whose last period was 3 weeks ago?  Second, what was that OTHER thing behind the uterus on the left?  Third, if the sac was really that big, why was there no pole?

The transvaginal exam was more or less to confirm my suspicions that this was not normal.  I knew that my plan was now to call the specialists with the fancy machine and adnexal expertise.  I couldn’t actually get a GOOD view in two planes (sorry, Dr. O’Brien!) due to patient discomfort, but this one was good enough.

longitudinal view, transvaginal probe

longitudinal view, transvaginal probe

I hadn’t seen any free fluid in her pelvis on either exam.  However, when OB came down, they found some.  They confirmed my suspicions and admitted the patient to go to the OR.

In my brief lit search just prior to posting, I found that this pseudosac finding is not extremely common (the average reported frequency is about 10% of cases).  I feel like this patient’s story would have raised enough red flags to make me uncomfortable sending her home without OB involvement even without the ultrasound, but the date/quant discrepancy coupled with a sac that was definitely not consistent (even though it WAS in the uterus) clinched the diagnosis for me.
