Shock and Hemodynamic Monitoring
Shock and Hemodynamic Monitoring Matthew Bank, MD, FACS Assistant Professor Hofstra North Shore‐LIJ School of Medicine Director, Surgical Intensive Care Unit North Shore University Hospital I do not have any financial conflicts of interest to disclose for this presentation Shock • Multiple different strategies for classifying shock, but all forms of shock result in impaired oxygen delivery secondary to either one or both: – reduced cardiac output (cardiogenic, septic) OR – loss of effective intravascular volume (hypovolemic, neurogenic, anaphylactic, septic). Septic Shock –Gram Negative • Gram negative septic shock: —Very studied well studied in animal models —Lipopolysaccharide (LPS) in bacterial cell wall binds to LPS binding protein. —LPS‐LBP complex then binds to cell surface CD14 receptors on monocytes and macrophages. —The LPS‐LBP‐CD14 complex then activates cells via Toll‐like receptor‐4 (TLR4). —TLR4 then “activates” cells which produce a cytokine “cascade” of proinflamatory mediators. Septic Shock –Gram Negative • Tumor Necrosis Factor (TNF) – First cytokine produced in response to gram negative sepsis – Principal mediator for acute response to gram negative bacteria – Major source of TNF is from activated macrophages – High levels of TNF predict mortality and can cause apoptosis. Septic Shock –Gram Negative • Interleukin‐1 (IL‐1) – Levels of IL‐1 increase soon after TNF production in gram negative sepsis (second cytokine to be elevated) – IL‐1 produced by macrophages, neutrophils and endothelial cells – IL‐1 increases levels of next proinflammatory cytokines in cascade, IL‐2 and IL‐12. – IL‐1 does NOT cause apoptosis Septic Shock –Gram Negative • Interleukin‐10 – Anti‐inflammatory cytokine – Inhibits production of IL‐12 – Inhibits T‐cell activation Septic Shock –Gram Positive • Gram positive sepsis – Gram positive cell wall components are also known to be involved in septic response – Peptidoglycans – Teichoic Acid – Likely act in a similar manner as LPS, but less potent on a weight bases. -

What Is Sepsis?
What is sepsis? Sepsis is a serious medical condition resulting from an infection. As part of the body’s inflammatory response to fight infection, chemicals are released into the bloodstream. These chemicals can cause blood vessels to leak and clot, meaning organs like the kidneys, lung, and heart will not get enough oxygen. The blood clots can also decrease blood flow to the legs and arms leading to gangrene. There are three stages of sepsis: sepsis, severe sepsis, and ultimately septic shock. In the United States, there are more than one million cases with more than 258,000 deaths per year. More people die from sepsis each year than the combined deaths from prostate cancer, breast cancer, and HIV. More than 50 percent of people who develop the most severe form—septic shock—die. Septic shock is a life-threatening condition that happens when your blood pressure drops to a dangerously low level after an infection. Who is at risk? Anyone can get sepsis, but the elderly, infants, and people with weakened immune systems or chronic illnesses are most at risk. People in healthcare settings after surgery or with invasive central intravenous lines and urinary catheters are also at risk. Any type of infection can lead to sepsis, but sepsis is most often associated with pneumonia, abdominal infections, or kidney infections. What are signs and symptoms of sepsis? The initial symptoms of the first stage of sepsis are: A temperature greater than 101°F or less than 96.8°F A rapid heart rate faster than 90 beats per minute A rapid respiratory rate faster than 20 breaths per minute A change in mental status Additional symptoms may include: • Shivering, paleness, or shortness of breath • Confusion or difficulty waking up • Extreme pain (described as “worst pain ever”) Two or more of the symptoms suggest that someone is becoming septic and needs immediate medical attention. -

Validation of Lactate Clearance at 6 H for Mortality Prediction in Critically Ill Children
570 Research Article Validation of lactate clearance at 6 h for mortality prediction in critically ill children Rajeev Kumar, Nirmal Kumar Background and Aims: To validate the lactate clearance (LC) at 6 h for mortality Access this article online prediction in Pediatric Intensive Care Unit (PICU)-admitted patients and its comparison Website: www.ijccm.org with a pediatric index of mortality 2 (PIM 2) score. Design: A prospective, observational DOI: 10.4103/0972-5229.192040 study in a tertiary care center. Materials and Methods: Children <13 years of age, Quick Response Code: Abstract admitted to PICU were included in the study. Lactate levels were measured at 0 and 6 h of admission for clearance. LC and delayed or nonclearance group compared for in-hospital mortality and compared with PIM 2 score for mortality prediction. Results: Of the 140 children (mean age 33.42 months) who were admitted to PICU, 23 (16.42%) patients died. For LC cut-off (16.435%) at 6 h, 92 patients qualified for clearance and 48 for delayed or non-LC group. High mortality was observed (39.6%) in delayed or non-LC group as compared to clearance group (4.3%) (P = 0.000). LC cut-off of 16.435% at 6 h (sensitivity 82.6%, specificity 75.2%, positive predictive value 39.6%, and negative predictive value 95.7%) correlates with mortality. Area under receiver operating characteristic (ROC) for LC at 6 h for mortality prediction was 0.823 (P = 0.000). The area under ROC curve for expected mortality prediction by PIM 2 score at admission was 0.906 and at 12.3% cut-off of PIM 2 Score was related with mortality. -

Approach to Shock.” These Podcasts Are Designed to Give Medical Students an Overview of Key Topics in Pediatrics
PedsCases Podcast Scripts This is a text version of a podcast from Pedscases.com on “Approach to Shock.” These podcasts are designed to give medical students an overview of key topics in pediatrics. The audio versions are accessible on iTunes or at www.pedcases.com/podcasts. Approach to Shock Developed by Dr. Dustin Jacobson and Dr Suzanne Beno for PedsCases.com. December 20, 2016 My name is Dustin Jacobson, a 3rd year pediatrics resident from the University of Toronto. This podcast was supervised by Dr. Suzanne Beno, a staff physician in the division of Pediatric Emergency Medicine at the University of Toronto. Today, we’ll discuss an approach to shock in children. First, we’ll define shock and understand it’s pathophysiology. Next, we’ll examine the subclassifications of shock. Last, we’ll review some basic and more advanced treatment for shock But first, let’s start with a case. Jonny is a 6-year-old male who presents with lethargy that is preceded by 2 days of a diarrheal illness. He has not urinated over the previous 24 hours. On assessment, he is tachycardic and hypotensive. He is febrile at 40 degrees Celsius, and is moaning on assessment, but spontaneously breathing. We’ll revisit this case including evaluation and management near the end of this podcast. The term “shock” is essentially a ‘catch-all’ phrase that refers to a state of inadequate oxygen or nutrient delivery for tissue metabolic demand. This broad definition incorporates many causes that eventually lead to this end-stage state. Basic oxygen delivery is determined by cardiac output and content of oxygen in the blood. -
