    Hello ladies and gentlemen. Welcome to our ongoing series of lectures on Anesthesiology. In this lecture I'm going to spend some time talking about Emergencies That Occur in the Operating Room. This is a highly selective group of emergencies we're going to discuss, one of which is unique to anesthesia, but extremely rare. So, this is the agenda for our talk. The first discussion is going to be on Malignant Hyperthermia. Then we're going to discuss Cardiac Arrest in several forms, including those forms that are treated through Advanced Cardiac Life Support programs. Hyperkalemic Arrest, which is not unique to anesthesia, but is certainly a problem in anesthesia and arrhythmias. We'll then talk about Massive Hemorrhage, Anaphylaxis, Head Injuries with increased intracranial pressure and how they're managed. For my own purposes I've divided emergencies in the operating room into three categories. One is Drug Induced, and that includes Malignant Hyperthermia, Anaphylaxis and Hyperkalemic Arrest. The second is Patient Induced. And don't think that I'm suggesting the patient purposely induces a problem. This is the patient who has some kind of medical problem that leads to a problem within the operating room. And this includes things such as Massive Hemorrhage, Brain Swelling and Increased Intracranial Pressure, and Ischemic Cardiac Arrest. And then the third category I called Doctor Induced or Iatrogenic emergencies, which include Wrong Drug, Wrong Dose, Wrong Side, Wrong Surgery and Surgeon Induced Hemorrhage. So we're going to start off talking about an extraordinary rare condition, but one that has a very high mortality if it's not diagnosed early. And this is malignant hyperthermia. This is a genetic disorder that is transmitted in an autosomal dominant genetic fashion. But it's extremely rare. It occurs in less than 1:1,000,000 people. The problem is that, when it does occur, it's highly...

    1. An extremely rare genetic disorder that can be triggered by certain anesthetic drugs.
    2. A condition which occurs commonly in the operating room.
    3. Is earliest diagnosed by rising temperature in the patient.
    4. Is nearly always fatal even when recognised and treated early.
    1. A cause of sudden intra-operative asystole and must be recognized as different from other causes of asystole.
    2. Is managed by rigidly following ACLS guidelines for asystole.
    3. Is completely unpredictable and cannot be caused by actions of the anesthesiologist.
    4. Is best treated by giving succinylcholine and intubating the patient.
