9/12/2014 What is Sepsis? Sepsis 2014: Emerging Trends in  Comes from the Greek meaning: Managing Severe Sepsis  “decay” or “to putrefy.”  Medical terms:  “the presence of pathogenic organisms or their toxins in the blood and tissues” Eric A. Reyer, DNP  or “the poisoned condition resulting from the ACNP, CCNS presence of pathogens or their toxins as in septicemia.” How Does it Occur? Where do the patients present? • Typically Bacterial in origin • 50% in the Emergency – Pneumonia – Cellulitis • Other in Hospital – UTI – ICU – Abdomen – Med-Surg – Medical Devices – OR – Procedures/Surgery • Basic vs. invasive • Fungal 1

9/12/2014 Insert CVC with ScvO2 Sepsis Management • CVP monitoring • Early Goal Directed Therapy – Transducer – Quick Identification • ScvO2 monitoring – Initial Labs and Fluid Resuscitation – Central Venous Catheterization 1. Achieve and Maintain CVP ≥ 8 mmHg 2. Achieve and Maintain MAP ≥ 65 mmHg – Requires advanced provider to place 3. Achieve and Maintain S c VO 2 ≥ 70% – Catheter more expensive BUT saves 40,000 per patient that develops sepsis!

9/12/2014 Other Considerations Barriers to Implementation? • Antibiotics in 1 Hours (Severe) • Providers • Urine Output monitoring – No time to insert central line – Not skilled to place IJ/Subclavian • Steroids – “I’m a physician, I know how to treat sepsis. I • Glucose Control don’t need a fancy machine to tell me what to do.” • CRRT • Nutrition • DVT/Stress Ulcer Prophylaxis Barriers to Implementation? Other Methods of Treatment • Nursing • Arterial Line CCO – Poor screening – Mainly use Stroke Volume Variation (SVV) • Computerized Charting? – Lack of education 6

9/12/2014 Other Methods Other Methods • Bioreactance (older bioimpedance) • Thermodilution – Arterial – PA Catheter Other Methods NEJM Sepsis Trial March 2014 • Lactate Clearance Research – Now a part of EGDT – NOT recommended as stand alone treatment • Flawed study- Small Much sicker patients in the • Only ED Original trials • 10% clearance Hawthorne effect? Clinicians • 6 hours only aware of all 3 arms • Only inhospital Adherence not 100% in EGDT 7
