Differentiating Between Anxiety, Syncope & Anaphylaxis
Differentiating between anxiety, syncope & anaphylaxis Dr. Réka Gustafson Medical Health Officer Vancouver Coastal Health Introduction Anaphylaxis is a rare but much feared side-effect of vaccination. Most vaccine providers will never see a case of true anaphylaxis due to vaccination, but need to be prepared to diagnose and respond to this medical emergency. Since anaphylaxis is so rare, most of us rely on guidelines to assist us in assessment and response. Due to the highly variable presentation, and absence of clinical trials, guidelines are by necessity often vague and very conservative. Guidelines are no substitute for good clinical judgment. Anaphylaxis Guidelines • “Anaphylaxis is a potentially life-threatening IgE mediated allergic reaction” – How many people die or have died from anaphylaxis after immunization? Can we predict who is likely to die from anaphylaxis? • “Anaphylaxis is one of the rarer events reported in the post-marketing surveillance” – How rare? Will I or my colleagues ever see a case? • “Changes develop over several minutes” – What is “several”? 1, 2, 10, 20 minutes? • “Even when there are mild symptoms initially, there is a potential for progression to a severe and even irreversible outcome” – Do I park my clinical judgment at the door? What do I look for in my clinical assessment? • “Fatalities during anaphylaxis usually result from delayed administration of epinephrine and from severe cardiac and respiratory complications. “ – What is delayed? How much time do I have? What is anaphylaxis? •an acute, potentially -

Lack of adequate perfusion can result in cell death, morbidity, and, ultimately, mortality. Hypovolemic shock is one of the most common categories of shock seen in clinical veterinary medicine.4 In hypovolemic shock, perfusion is impaired as a result of an ineffective circulating blood volume. During initial circulating volume loss, there are a number of mechanisms to com- pensate for decreases in perfusion, including increased levels of 2,3-Bisphosphoglycerate, result- ing in a rightward shift in the oxyhemoglobin dissociation curve and a decreased blood viscosity. -
Jugular Venous Pressure
NURSING Jugular Venous Pressure: Measuring PRACTICE & SKILL What is Measuring Jugular Venous Pressure? Measuring jugular venous pressure (JVP) is a noninvasive physical examination technique used to indirectly measure central venous pressure(i.e., the pressure of the blood in the superior and inferior vena cava close to the right atrium). It is a part of a complete cardiovascular assessment. (For more information on cardiovascular assessment in adults, see Nursing Practice & Skill ... Physical Assessment: Performing a Cardiovascular Assessment in Adults ) › What: Measuring JVP is a screening mechanism to identify abnormalities in venous return, blood volume, and right heart hemodynamics › How: JVP is determined by measuring the vertical distance between the sternal angle and the highest point of the visible venous pulsation in the internal jugular vein orthe height of the column of blood in the external jugular vein › Where: JVP can be measured in inpatient, outpatient, and residential settings › Who: Nurses, nurse practitioners, physician assistants, and treating clinicians can measure JVP as part of a complete cardiovascular assessment What is the Desired Outcome of Measuring Jugular Venous Pressure? › The desired outcome of measuring JVP is to establish the patient’s JVP within the normal range or for abnormal JVP to be identified so that appropriate treatment may be initiated. Patients’ level of activity should not be affected by having had the JVP measured ICD-9 Why is Measuring Jugular Venous Pressure Important? 89.62 › The JVP is -

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. -
The Carotid Bruit on September 25, 2021 by Guest
AUGUST 2002 221 Pract Neurol: first published as 10.1046/j.1474-7766.2002.00078.x on 1 August 2002. Downloaded from INTRODUCTION When faced with a patient who may have had a NEUROLOGICAL SIGN stroke or transient ischaemic attack (TIA), one needs to ask oneself some simple questions: was the event vascular?; where was the brain lesion, and hence its vascular territory?; what was the cause? A careful history and focused physical examination are essential steps in getting the right answers. Although one can learn a great deal about the state of a patient’s arteries from expensive vascular imaging techniques, this does not make simple auscultation of the neck for carotid bruits redundant. In this brief review, we will therefore defi ne the place of the bruit in the diagnosis and management of patients with suspected TIA or stroke. WHY ARE CAROTID BRUITS IMPORTANT? A bruit over the carotid region is important because it may indicate the presence of athero- sclerotic plaque in the carotid arteries. Throm- boembolism from atherosclerotic plaque at the carotid artery bifurcation is a major cause of TIA and ischaemic stroke. Plaques occur preferentially at the carotid bifurcation, usually fi rst on the posterior wall of the internal carotid artery origin. The growth of these plaques and their subsequent disintegration, surface ulcera- tion, and capacity to throw off emboli into the Figure 1 Where to listen for a brain and eye determines the pattern of subse- bifurcation/internal carotid quent symptoms.

Towards Non-Invasive Monitoring of Hypovolemia in Intensive Care Patients Abstract Hypovolemia caused by internal hemorrhage is a major cause of death in critical care patients. However, hypovolemia is difficult to diagnose in a timely fashion, as obvious symptoms do not manifest until patients are already nearing a critical state of shock. Novel non-invasive methods for detecting hypovolemia in the literature utilize the photoplethysmogram (PPG) waveform generated by the pulse-oximeter attached to a finger or ear. -
