Potassium and sodium derangements usually do not require short-term treatment beyond fluid resuscitation and hydrocortisone. Common Pitfalls • Intravenous (IV) fluid for volume expansion is not delivered in a rapid and/or controlled manner. – IV “wide open” fluid administration can lead to very rapid infusion of a whole liter of fluid OR can result in underresuscitation if there is significant re- sistance to flow (small IV gauge). Infants and small children should always receive resuscitation fluids using a pump or push to allow for observation and control of fluid delivery. Pressure bags can increase the likelihood of excessive fluid overload. – Pushing fluid is accomplished by attaching a three-way stopcock in line with the IV catheter and pulling fluid directly from the bag (step 1) and then switching the stopcock and pushing the fluid into the patient. • Failing to check a bedside glucose level. Hypoglycemia is not always present in patients with congenital adrenal hyperplasia and salt-wasting crisis, but it can occur. • Delaying treatment with hydrocortisone to obtain diagnostic tests. 3 Simulation Scenarios Adrenal Insufficiency © 2015 by the American Academy of Pediatrics and the American College of Emergency Physicians Blunt Abdominal Trauma—Hypovolemic Shock Adam Cheng, MD, FRCPC, FAAP Mark Adler, MD Learning Objectives • Describe the signs and symptoms of a patient with hypovolemic shock. • Demonstrate the management of circulatory failure due to hypovolemic shock. – Demonstrate the approach to pediatric trauma: primary and secondary assessment. – Demonstrate use of fluid resuscitation in patients with profound blood loss. – Identify and manage abdominal injury in a trauma patient. – Demonstrate use of rapid infuser in trauma care.

  • Public Access Defibrillation/AED Program Implementation Guide
    Public Access Defibrillation/AED Program Implementation Guide There are 4 key elements to establishing a Public Access Defibrillation program. These include: Having designated rescuers trained in CPR and in how to use an automated external defibrillator (AED) Having a physician to provide medical oversight and direction Integrating your program with the local emergency medical services (EMS) system Using and maintaining the AED(s) according to the manufacturers specifications Steps: 1. Gain consensus Within your company or organization begin to identify the key decision makers and arrange a meeting to gain support. The American Heart Association or your local EMS Agency can assist you with presentation materials. 2. Review the law and regulations Review Federal, State and local laws and regulations regarding Public Access Defibrillation program requirements. Consult your local Emergency Medical Services (EMS) Agency The California laws ang regulations that pertain to AEDs are Title 22, and AB 658. 3. Consult your local Emergency Medical Services (EMS) Agency The local EMS Agency can provide you with information regarding training, purchasing AEDs, medical direction and laws and regulations. 4. Identify your response team Identify who would be most likely to respond in an emergency – this will help determine how and where AEDs are mounted or stored. 5. Select equipment and vendor Some considerations in selecting the AED may include: Reputation of the AED manufacturer for the product’s quality and customer service, compatibility with the equipment used in the local EMS system, and ease of operation of the AED. 6. Design Policies and Procedures These may include: Who manages the AED program When the AED should be used, when it should not be used Training required to use the AED Locations of AEDs and other equipment (such as gloves and pocket mask for CPR) Notification process for internal AED responders and external emergency medical services responders Maintenance schedule for equipment Training and refresher training policies 7.

  • PUBLIC ACCESS to AUTOMATED EXTERNAL DEFIBRILLATORS (Aeds) FACTS
    POSITION STATEMENT PUBLIC ACCESS TO AUTOMATED EXTERNAL DEFIBRILLATORS (AEDs) FACTS • Cardiac refers to the heart. Arrest means stop. Sudden cardiac arrest is the sudden and unexpected loss of heart function. • Signs of cardiac arrest include: no breathing or only gasping, no movement, and no pulse. • Up to 40,000 cardiac arrests occur each year in Canada. That’s one cardiac arrest every 12 minutes. Without rapid and appropriate treatment, most of these cardiac arrests will result in death. Thousands of lives could be saved through public access to automated external defibrillators. • An automated external defibrillator (AED) is a small, portable device used to identify cardiac rhythms and deliver a shock to correct abnormal electrical activity in the heart. As a result of the sophisticated electronics in an AED the operator will only be advised to deliver a shock if the • A landmark study of the City of Chicago airports public heart is in a rhythm which can be corrected by defibrillation. access to AED program showed survival rates as high as If a shockable rhythm is not detected, no shock can be 75%.

Overview Sudden cardiac arrest (SCA) remains a major unresolved public health problem; each year in the United States alone, sudden cardiac arrest strikes more than 350,000 people—nearly 1,000 per day—making it the single leading cause of death.1,2 Due in part to the unexpectedness with which SCA strikes, most of these victims die before reaching a hospital. Currently, the chances of surviving an SCA in the United States are less than one in 20. Experts agree that many of the deaths due to SCA are preventable and that available technology, if appropriately applied, could reduce them significantly at a relatively low cost.3 The vast majority of sudden cardiac arrests are due to abnormal heart rhythms called arrhythmias, of which ventricular fibrillation is the most common.

  • The Powerheart® Family of Products
    The Powerheart® family of products AT THE HEART OF SAVING LIVES.TM When you bring AEDs to your facility, you empower teachers, employees, and/or bystanders all to become part of the chain of survival According to the American Heart Association (AHA) and European Resuscitation Council (ERC), a sudden cardiac arrest (SCA) victim requires 911 defibrillation to stop ventricular fibrillation (VF), an often-fatal heart abnormality. The sooner the defibrillation, the better the victim’s chances of survival – precisely why having your own automated external defibrillator (AED) to use while you're waiting for emergency medical responders is so important. Time is the critical factor Several studies document the effects of time to defibrillation and the effects of bystander cardiopulmonary resuscitation (CPR) on surviving SCA. For every minute that passes between collapse and defibrillation, survival rates for witnessed VF SCA decrease 7 to 10 percent if no CPR is provided. VF rarely converts spontaneously. It’s ultimately a defibrillator that saves lives. Make sure you have one when it’s needed. 100 80 60 40 Percent Survival Rate Percent 20 0 12345678910 Minutes to Defibrillation Shock Did you know?
