Beyond the basics: right vs. left heart failure.

Heart failure is a pathophysiologic cascade that, if improperly identified and managed, may lead to death. If heart failure is identified early enough, development of irreversible end-stage heart failure may be avoided. The goal of the prehospital care provider in managing heart failure is directed at maintenance of adequate cellular oxygenation, reduction of preload and afterload to improve forward blood flow, and, ultimately, improve cardiac output.

Beyond the basics: pediatric assessment.

Some children, regardless of what is done for them, will get sick and die. Fortunately, this is more rare than regular. An EMS provider who appropriately assesses a sick child with a potential to survive will be able to identify life-threatening conditions and manage those conditions. The most common cause of pediatric death is hypoxia. A hypoxic child without proper intervention will ultimately experience cardiovascular collapse and eventually death. Most healthy children have no difficulty in maintaining normal cardiovascular function until and unless they become extremely hypoxic. EMS providers must understand that the most effective management processes require an understanding of why children present in the way they do. If an assessment is not thorough and accurate, a child may continue to deteriorate. Assessment is the key to pediatric management.

Beyond the basics: trauma assessment.

Your patient assessment, including a history and, more important, in the trauma patient, the physical exam, and the mechanism of injury will determine treatment and transport priorities. The No. 1 consideration in managing the trauma patient is to establish and maintain an effective airway, ventilation, oxygenation and circulation. Recognizing that the trauma patient needs immediate definitive intervention, an on-scene time of less than 10 minutes is desirable. When determining transport priorities, the EMS provider must decide if delaying transport to perform a procedure is necessary to sustain the patient throughout transport. If it is not a critical procedure, it should be performed en route to the trauma center. Due to the extent of injuries, some trauma patients will die regardless of your most proficient assessment and emergency care.

Cardiogenic shock.

Cardiogenic shock is a pathophysiologic cascade that often leads to death. Although there has been a dramatic decrease in the cases of cardiogenic shock since the 1970s, the mortality rate of those patients who are diagnosed with cardiogenic shock remains as high as 50% to 80%. As stated throughout the article, cardiogenic shock in its later stages cannot be reversed, but clinical signs and symptoms of the syndrome may be identified early enough to prevent a patient from developing irreversible end-stage cardiogenic shock. As a prehospital care provider, you must be able to ensure the pre-shock patient has adequate oxygenation of the myocardium and can be effectively treated before it is too late.
