Morning Report – Fluid Responsiveness

Resident Presenter: Patrick Charles

Topic: Fluid Responsiveness Series (part 1 of 2)
45 yo M with a PMHx of DM and HTN presents with SOB and fever. He
complains of progressively worsening fatigue and cough over the last few days
and developed acute onset fever, shaking chills, and difficulty breathing on the
day of presentation. His vitals are 101.5oF, 132, 22, 90/44, 94% RA. Physical
examination reveals right lower lung field crackles, and a chest x-ray
demonstrates a right lower lobe infiltrate.
What do you do next?
How many liters would you empirically give this patient?
When do you pull the trigger and start pressors?
Learning Points:
synonymous with the fact that the patient needs more
– Fluid responsiveness does not mean that a patient
should be given fluids!
– Fluid Responsiveness = An increase in their stroke
volume (SV) by 10–15% via rapid infusion of 500 ml of
crystalloid (fluid challenge) or straight leg raise thus
improving CO if the patient falls on the preload zone of
the Frank-Starling Curve.
– If there is compressibility (or distensibility in a ventilated
patient) of the IVC >20% and <50% then evaluate for
fluid responsiveness. Perform a passive leg raise while
reassessing the IVC if the IVC collapse <20% then the
patient may not be a fluid responder
– The data clearly established that there is a poor relationship between the CVP
and the intravascular volume status, and no relationship between the CVP and
fluid responsiveness.
– CVP and PCWP are static tests that are less sensitive, less specific and less
useful that dynamic tests (i.e.
passive leg raising)

Preau et al: A prospective study in
France that looked at 34 ICU
spontaneously breathing patients.
They performed passive leg raising
which equates to a 500cc rapid
volume expansion. They concluded
that stroke volume increased >/= 10%
after a volume expansion = passive
leg raise were responders which
predicted fluid responsiveness with
sensitivity of 86% and specificity of
90%. The pulse pressure increase of
>/= 9% which predicted fluid
responsiveness with sensitivity of 79%
and specificity of 85%. The velocity of
femoral artery flow increase of >/= 8%
which predicted fluid responsiveness
with a sensitivity of 86% and specificity
of 80%. This concluded that passive
leg raising are accurate and
interchangeable indices for predicting
fluid responsiveness in non-intubated
– Kircher et al: reported that Caval Index (CI) >50% was strongly associated with
a CVP <8 mm Hg and futhermore was indicative of right atrial (RA) pressures
<10 mm Hg. In comparison the CI <50% was associated with a CVP >12 and
indicated RA pressures >10 mm Hg
– (Step 1) If the CI is <50% perform a TTE and Lung US (e.g. hyperdynamic heart
and no B-lines) to assess if the patient can handle more fluids. (Step 2) If so add
Levophed (or vasopressor of your choice). (Step 3) After a few minutes repeat
passive leg raise and assess if the patient is a responder.
– respirophasic changes in intrathoracic pressure are difficult to quantify when the
inspiratory force itself cannot be measured or standardized in a spontaneous
breathing patient
– location at which measurements are obtained varies greatly in the literature –
caudal to the junction of the middle hepatic vein, approximately 2 to 4 cm from
the IVC/RA junction
– craniocaudial movement – Mechanical displacement of the diaphragm during
respiration frequently results in measurement of the IVC at 2 different locations
during inspiration and expiration, and the IVC exhibits different degrees of
collapsibility at different locations along its course
– subcostal window may not afford adequate visualization of the IVC, particularly
in patients with obesity, abdominal pain, gastric insufflation, large amounts of
bowel gas, or post-surgical wounds and/or pneumoperitoneum.
-IVC diameter and CI are significantly influenced by pulmonary hypertension,
tricuspid regurgitation, tachycardia and variations in tidal volumes and patterns of
respiration in spontaneously breathing patients. abdominal compartment

Morning Report – Atypical Cause of Chest Pain

Resident Presenter: Molly Malone PGY1

Topic: Atypical Cause of Chest Pain


Patient is a 70 year old female with a PMHx significant for HTN, HLD, COPD, diaphragmatic hernia and anxiety presenting to the ED for chest pain x5 days. Pt reports the pain is located in her b/l chest and radiates to her b/l back. She categorizes it as 8/10, persistent lower rib cage pain, sharp in nature, and exacerbated with deep breathing. Pt endorses mild relief with Advil and 2 episodes of emesis yesterday. Pt denies, SOB, cough, abdominal pain, nausea, or fever.

Initial vitals: T: 36.4°C | HR: 101 | BP: 100/68 | RR: 16 | O2 Sat: 97% RA

Pt was in NAD had an unkempt odor about her and physical exam was unremarkable except for tachycardia and b/l chest tenderness.

Initial plan was for ACS work up including EKG, CXR, labs, Trops. When these came back negative the work up was extended to include PE. The patient received a CT-PE and was found to have:

“Mural thickening and adjacent stranding of the mid to distal esophagus. Within the esophagus just proximal to the GE junction there is a questioned focus of intramural air possibly reflecting a Mallory-Weiss tear. No evidence of mediastinal emphysema”


Learning Points:

  • Atypical causes of chest pain: Mallory-Weiss tear, Boerhaave Syndrome, Diaphragmatic Hernia
  • Upright CXR, Esophogram, CT-chest
  • Treatment for Boerhaave: Conservative and Operative
    • 1st call to CT surgery
    • Conservative Management – Disruption contained in the mediastinum or between the mediastinum and visceral lung pleura; drainage of the cavity back into the esophagus; minimal symptoms; and minimal signs of clinical sepsis
    • Volume resuscitation – IVF and broad spectrum antibiotics to include anaerobes
  • Toby Factor: effusion usually occur and are seen in the LEFT plural cavity

Morning Report – Psoas Abscess

Presenter: Emily Sze PGY-1

Topic: psoas abscess

Summary: In this case, a 47-year-old male presents to the ED complaining of 2 weeks of worsening of his chronic lower back and abdominal pain, along with nausea, vomiting, diarrhea, and dysuria. He is a current IVDU, most recently injected heroin 1 week ago, and was previously in a methadone program. He also smoked crack a few days ago. He had his appendix removed as a teenager. He was seen at Bon Secours hospital a few days ago for the same complaint and sent home with oxycodone and Valium.

On exam: 37.3C (99.1F), intoxicated, +ttp abdomen, –ttp spinal/paraspinal region, neuro exam normal.

Work-up: wbc count 19.9, mild anemia hgb 10.9, wet abd CT showed a psoas abscess of size 1.8x2cm.

Learning points:

  • Always consider psoas abscess in differential for lower back pain, particularly in a patient with risk factors
  • Psoas abscess has high mortality rate (2.4% for primary, 18.9% for secondary), usually due to sepsis from delayed diagnosis/treatment
    1. Look for +psoas sign, position of comfort (hip flexion/lumbar lordosis)
  • Primary psoas abscess – caused by hematogenous/lymphatic spread (20-60% of psoas abscesses in USA)
    1. Risk factors:
      1. IVDU
      2. Immunosuppression (diabetes, renal failure, HIV, etc)
  • Epi: males, childhood to young adulthood, tropical/developing countries
  1. Bugs: Staph aureus (#1), including MRSA; Mycobacterium tuberculosis in endemic areas -> vancomycin, clindamycin, linezolid
  • Secondary psoas abscess – caused by direct spread
    1. Risk factors:
      1. Trauma
      2. Vertebral osteomyelitis, especially from Pott’s disease
  • Crohn’s ileocolitis (0.4-4.3% incidence)
  1. Infected aortic aneurysm (20% incidence)
  2. Ruptured renal or pancreatic abscess
  3. Septic hip arthritis (hip bursa communicates with iliopsoas bursa in 15% of people
  • Iatrogenic: instrumentation, epidural catheter, total hip arthroplasty (12%), shock wave lithotripsy, nephrectomy
  1. Bugs: usually enteric, often polymicrobial ? Zosyn, fluoroquinolone, cephalosporin, Flagyl
  • Imaging: dry CT, wet CT, MRI are options
    1. Sensitivity for all 3 modalities is 100% after 6 days of symptoms
    2. Earlier than 6 days, sensitivity is 33%, 50%, and 50%

Article of the Week 10-21-15

Hi Colleagues,

EBM Article of the Week: It’s the hot-off-the-presses AHA guidelines for CPR.
It’s hard to get excited about guidelines but you will notice a few changes to cardiac arrest resuscitation.
Notable changes include…
– No longer using Vasopressin in place of Epi.
– Amiodarone>Lidocaine
– Mg should not be used routinely.
– ETCO2 to monitor for correct ETT placement and predictor of survival.
