Take-Home Points
  1. Endocarditis can have vague and varied presentations and has high morbidity and mortality. Be on the lookout in patients with risk factors including: 
    1. Congenital heart disease
    2. Cardiac prosthesis or devices
    3. Immunocompromise
    4. IV drug use
    5. Recent invasive procedure
    6. Hx of prior IE
  2. Patients may present with fever, sepsis of unclear source or may have manifestations of emboli to the skin, eyes, brain, lungs, spleen or kidney.
  3. Diagnosis is based on the modified Duke Criteria and workup should include THREE good sets of blood cultures. 
  4. ED management includes consultation with ID and cardiothoracic surgery and starting antibiotics based on whether the patient has a native or prosthetic valve. Basic starting antibiotic regimen includes:
    1. For patients with native valve disease a good starting regimen is:
      1. Vancomycin 25-30 mg/kg IV loading dose followed by 15-20 mg/kg twice daily AND
      2. Cefepime 2 g IV TID
    2. For patients with prosthetic valve disease, we have to go a bit bigger:
      1. Vancomycin 25-30 mg/kg IV loading dose followed by 15-20 mg/kg IV twice daily AND
      2. Rifampin 300 mg PO/IV TID AND
      3. Gentamicin 1 mg/kg IV TID AND
      4. Some recommendations include the Cefepime 2 g IV TID

The use of heated and humidified high flow nasal cannula (HFNC) has become increasingly popular in the treatment of patients with acute respiratory failure through all age groups.  Over the past several years, many studies have come out reviewing the mechanisms of action as well as its use in a variety of conditions.  In this episode, I will summarize how it works and for part 2, I will discuss the main indications for its use in both adult and pediatric patients and practical tips on how to use it.

Take Home Points

  • When compared to 0.9% saline, lactated ringers is a more balanced solution and more closely resembles our serum.
  • SALT ED and SMART trials show normal saline may increase the occurrence of major adverse kidney events in comparison to a balanced solution like LR. For large volume resuscitations, LR is a better choice.
  • Certain medications cannot be run with LR in the same IV line. Ampicillin, Carbapenems, Phenytoin, Potassium Phosphate, Nicardipine
  • Ceftriaxone and LR should never be running at the same time in children less than 28 days old.

Background: The combination of vitamin C, hydrocortisone and thiamine in sepsis has been a topic of hot debate in the past couple years.  There is a hypothetical pathophysiological basis to make an argument for the use of this combination of medications, but as with anything it is important to ensure there are no untoward effects either. In Dr. Marik’s before and after study [1] we saw some pretty amazing results showing that treatment reduced hospital mortality  by 31.9% (Treatment Group 8.5% vs Control Group 40.4%). Too good to be true?  Well in short, YES…the major issues with this study were it was not a randomized controlled trial, had a small sample size, was a single center study, and had significant selection bias.  Well we finally have our first randomized controlled trial evaluating the “metabolic cocktail” in a general population of septic shock adult patients.

Take Home Points 
  • Osteomyelitis is an infection in any part of a bone. It has a varied presentation including acute and chronic forms. Patients can present septic, or rather well appearing.
  • Patients may present with fever, chills, musculoskeletal pain, erythema, swelling or drainage from an ulcer.
  • Lab evaluation includes WBC, ESR and CRP, which we expect to be elevated in acute osteo, but less so in chronic.
  • MRI is the best imaging modality, but XR and CT may have some findings that suggest osteo.
  • Unstable patients should be started on broad spectrum antibiotics, usually vancomycin and cefepime, right away. Stable patients can be started on antibiotics in conjunction with your orthopedic consults.
