Neutropenic sepsis is the development of a profound and potentially life-threatening episode in patients that are extremely vulnerable due to their diminished ability to fight off infection. This reduced capacity to respond to infective agents – neutropenia—is caused by a near total absence of the body's specialist white cells, called neutrophils. One of the most commonly found causes of neutropenia are the chemotherapy regimens that patients treated for cancer need to take. There are an increasing number of such regimens being prescribed and, also, a trend towards oncology patients being treated—or recovering from treatment - at home (Dikken, 2009). The initial signs of these patients becoming overwhelmed by an opportunistic infection are easy to miss as the signs and symptoms are vague. The importance of sepsis being suspected and responded to by paramedic staff is of the utmost importance, as the disease process will progress with alarming speed to a point where it is difficult to support or resuscitate the patient either in the community or in hospital settings.
