Round 5 (MW) – Leg Pain

You are working at Clerkship General Hospital when EMS calls in a female with opioid overdose, but she won’t stop complaining of leg pain…

Initial Vitals:

Temp: 98

BP: 120/80

HR: 89

RR: 20

O2 Sat: 100%

Critical Actions:

  • Treat patient’s pain without NSAIDs (history of solitary kidney)
  • Assess patient’s leg pain beyond the point of just fracture vs. no fracture
  • Recognize the signs and symptoms of compartment syndrome
  • Get orthopedic surgery to bedside emergently for fasciotomy
  • Recognize and treat rhabdomyolysis

Deep Dive MW R4

Diabetic Ketoacidosis – hyperglycemia, ketosis, and anion gap metabolic acidosis

  • Don’t forget about euglycemic DKA (especially in setting of SGLT2 inhibitor) or mimics such as alcoholic ketoacidosis
  1. Treatment of the ketoacidosis
    • Insulin (usually a drip or bolus + drip) – only once K>3.5
    • Volume Resuscitation (NS initially, change to LR)
    • Bicarb drip (poor evidence, only as last resort for critical patients)
  2. Treatment of electrolyte abnormalities
    • Correct sodium for hyperglycemia
    • Replete potassium if K<5.0, PO and IV simultaneously
      • consider central line if patient hypokalemic and in extremis/critical DKA
  3. Management of respiratory status
    • Avoid intubation at all costs unless altered or impending respiratory failure
      • APNEA KILLS
      • Mechanical ventilation limits your minute ventilation, leading to worsening acidosis. Breath stacking occurs if you set the RR too high.
    • Support work of breathing with NIPPV (high IPAP, low EPAP)
    • If intubation necessary, consider awake intubation or consider using bicarb pushes if performing RSI

Summary of Key Points

1. You should consider ectopic pregnancy in every patient who is capable of bearing children

2. If a patient of child bearing age presents with severe abdominal pain or vaginal bleeding and is either hemodynamically unstable or very ill appearing, this is a ruptured  ectopic pregnancy until proven otherwise and I would recommend performing a bedside FAST exam immediately.

3. Remember that the discriminatory zone for TVUS is approximately 1500.  

4. Don’t forget your three ACEP clinical policies on this topic: just to remind you, 

4a.  It is a level B ACEP clinical policy to obtain a TVUS in every stable pregnant patient presenting with abdominal pain or vaginal bleeding, regardless of serum b-HCG level

4b.  There is also a level B ACEP clinical policy stating that in patients with an indeterminate TVUS, you cannot use serum bHCG value to rule out ectopic pregnancy.

4c. It is a level C ACEP clinical policy to obtain specialty consultation or arrange close outpatient followup in all patients with an indeterminate TVUS result.

5. Although this isn’t an ACEP recommendation, ACOG recommends rhogam for all Rh negative women diagnosed with an ectopic pregnancy

6. Don’t forget to consider heterotopic pregnancy, especially if IVF was used to help conceive.

Round 24 (Altered Mental Status)

CAUTION: THESE NOTES CONTAIN SPOILERS!!

Case Introduction

You are working a shift at EM Clerkship General when you receive a radio call from EMS who are bringing in a young female who was found unresponsive.

Initial Vitals

  • Temp 98.0F
  • HR 97
  • RR 16
  • BP 120/80
  • O2 98%

Critical Actions

  • Obtain collateral history from EMS/friends
  • Administer Naloxone as needed for respiratory depression
  • Obtain 0-hour and 4-hour acetaminophen levels
  • Administer N-acetyl-cystine
  • Obtain psychiatry consult for suicidal ideation

Torsades de Pointes (Deep Dive R21)

Torsades de Pointes (TdP)

A type of polymorphic ventricular tachycardia that is inherently unstable and often quickly degrades into ventricular fibrillation. It usually occurs in the setting of a prolonged QT interval, which can either be genetic or acquired.

Treatment

  1. Defibrillation – per ACLS, ventricular tachycardia with a pulse should receive synchronized cardioversion. But in real life, the defibrillator often isn’t able to “sync” with TdP, forcing you to perform unsynchronized cardioversion (aka defibrillation).
  2. IV Magnesium – treats and prevents TdP, even when magnesium levels are normal
  3. Overdrive Pacing – by preventing bradycardia, we help prevent TdP (bradycardia prolongs the QT interval).
    • Electrical Overdrive Pacing – transcutaneous or transvenous pacemaker
    • Chemical Overdrive Pacing – beta agonist therapy (isoproterenol)
  4. Lidocaine – anti-arrhythmic therapy that does not prolong QTc.
  5. Fix underlying cause – congenital long QT syndrome, hypokalemia, hypocalcemia, medication induced (psych meds, anti-emetics, methadone, fluoroquinolones, many more)

Defibrillation and IV Magnesium are used for patients who are ACTIVELY in TdP. Once you shock/mag them into a stable rhythm, you can use Overdrive Pacing / Lidocaine / Treat Underlying Cause to PREVENT them from going back into TdP.

Identification of Sepsis (Deep Dive R18)

Four definitions you must know:

  1. SIRS – Must have at least 2 of 4 SIRS criteria (listed below):
    • Fever (>38C) or Hypothermia (<36C)
    • WBC >12k or <4k ; OR Bandemia >10%
    • Tachycardia > 90
    • Tachypnea > 20
  2. SEPSIS – Must have SIRS + have a suspected infectious source (eg pulmonary, urinary, intra-abdominal, etc)
  3. SEVERE SEPSIS – Must have Sepsis + ONE of the following criteria indicative of end organ dysfunction:
    • Hypotension (MAP<65 or SBP<90)
    • Creatinine > 2.0 (with normal baseline renal function)
    • Lactate > 2.0
    • Platelets < 100k
    • INR > 1.5
    • Bilirubin > 2
  4. SEPTIC SHOCK – Must have severe sepsis PLUS one of the following
    • Hypotension DESPITE adequate fluid resuscitation (usually 30cc/kg bolus)
    • Lactate > 4.0 DESPITE adequate fluid resuscitation (usually 30cc/kg bolus)

GENERAL GUIDELINES (exact management depends on clinical scenario):

  • If patient meets SIRS criteria you work the patient up for sepsis / severe sepsis:
    • Lactate, Blood Cultures, Urinalysis/Culture, Chest XRay
    • CBC, BMP, Coags, LFTs
  • If patient meets SEPSIS criteria, you add in broad spectrum antibiotics +/- intravenous fluids
  • If patient meets SEVERE SEPSIS criteria, you give a 30cc/kg fluid bolus,
  • If patient meets SEPTIC SHOCK criteria and is HYPOTENSIVE, you start vasopressors (norepinephrine usually)
