It is key for HCA/APs to be alert to signs of anaphylactic shock

This article provides the healthcare assistant and assistant practitioner (HCA and AP) with information regarding a life-threatening condition: anaphylactic shock, which is a serious allergic reaction. The incidence of anaphylactic shock in the UK is increasing. Shock results in an acute widespread decrease in effective tissue perfusion, which causes an imbalance in oxygen supply and demand, along with a variety of other adverse actions. Vital organs and tissues may be ineffectively perfused. The article discusses antibody and antigen interactions and the results that occur when there is an allergic response. A discussion concerning the pathophysiological changes that occur in conjunction with anaphylactic shock is offered. The signs and symptoms are described and the management of the condition is highlighted. The role of the HCA and AP are briefly addressed. Health education activities are described. A glossary of terms is provided.
