Elderly people die from abdominal pain

Step 1: Risk Stratify

  • Certain patient groups have VERY high mortality when having abdominal pain
    • Geriatrics
    • Immunocompromised
    • Diabetics

Step 2: Consider Genitourinary Causes

  • Be especially cautious with lower abdominal/flank pain
    • Mention that you performed or considered performing GU exam during presentation!
  • Common GU causes of abdominal pain
    • Testicular/ovarian torsion
    • Prostatitis/pelvic inflammatory disease
    • Ectopic pregnancy

Step 3: High-Yield Tests to Consider

  • CBC and Electrolytes
  • EKG and Troponin
  • Liver Panel and Lipase
  • Urinalysis and Urine pregnancy

Step 4: Order Appropriate Imaging

  • CT scan is most useful test with abdominal pain in adults
    • Need to give IV contrast if concerned for vascular pathology
    • Usually performs just as well as ultrasound (even in cases where ultrasound is the classic, initial test)
  • 3 “exceptions” to the CT first rule
    • If concerned for biliary pathology
      • RUQ ultrasound
    • If concerned for genitourinary pathology
      • Testicular/Pelvic ultrasound
      • Renal ultrasound (kidney stone)
    • If concerned for Abdominal Aortic Aneurysm
      • Bedside Aorta ultrasound

Step 5: Disposition

  • Classic teaching is that patients discharged with undifferentiated abdominal pain need follow up in 12-24 hours
  • It’s ok to have them come back to the ED if necessary

Get your attending!

Step 1: Obtain Last Known Well

  • Stroke treatments including tPA and thrombectomy both require last known well
    • <3-4.5 hours for tPA
    • <24 hours mechanical thrombectomy

Step 2: Finger Stick Blood Glucose

  • Hypoglycemia is classic mimic of CVA
  • Results can be obtained immediately

Step 3: STAT Head CT Without Contrast

  • Poor sensitivity for ischemic stroke
    • Primary use is identification of hemorrhagic stroke
    • Required prior to administration of tPA!

Step 4: Perform NIHSS

Step 5: Give tPA (If No Contraindications)

  • Follow department protocol and contraindications
    • Frequently being updated

You have 90 minutes to restore blood flow.

Step 1: Obtain EKG and Call STEMI Alert

  • This activates ED resources as well as cath lab, interventional cardiology, etc

Step 2: Stop the Platelets

  • Dual anti-platelet therapy
    • Aspirin 325mg chewed (or PR)
    • Plavix 600mg (not usually given in ED)
      • Complicates management if patient needs CABG

Step 3: Stop the Coagulation Cascade

Step 4: Patient Should (Ideally) Be Going to Cath Lab By Now

  • If you DON’T have cath lab
    • Option 1: 30 minutes to give thrombolytics
    • Option 2: 120 minutes to get them to a different hospital with cath lab

Sgarbossa Criteria

Priapism

May 30, 2016 /

Podcast: Play in new window | Download

The nerve, artery, and vein are at 12 o’clock. The urethra is at 6 o’clock.

Two Types of Priapism

  • High flow (non-ischemic)
    • Common causes
      • Trauma
      • AV malformations
      • Tumors
    • Priapism from too much blood coming IN
    • Not painful
    • Consult urology
  • Low flow (ischemic)
    • Common causes
      • Sickle cell disease
      • Drug side-effects
    • Priapism from blood being unable to flow OUT
    • Patient requires emergent detumescence
      • 50% chance of erectile dysfunction

Step 1: Prepare (4c approach)

  • Collect
    • 19G needle
    • 21G needle
    • Variety of syringes
    • Gauze
    • Sterile drape
    • Betadine
    • Normal saline
  • Consent
    • 50% chance of erectile dysfunction even with successful procedure
  • Clean
    • Set up supplies and sterile field
  • Control pain

Step 2: Drain

  • Nerve/Artery/Vein on top (12 o’clock)
  • Urethra on bottom (6 o’clock)
  • Insert 19G needle at either 3 or 9 o’clock and aspirate
    • UPDATE: Recommended insertion at either 2 or 10 o’clock
  • 30% chance of detumescence at this step alone

Step 3: Send Venous Blood Gas

  • Confirms high-flow (non-ischemic) from low-flow (ischemic) priapism

Step 4: Irrigate

  • Inject normal saline through the needle and then aspirate

Step 5: Phenylepherine

  • Dilute 1ml (10 mg/ml) in 9 ml NS (results in 1mg/ml solution)
    • Inject 0.25 ml of 1 mg/ml solution and repeat q10 minutes
    • Alpha agonist effect constricts smooth muscle and facilitates venous outflow
