Shock is a general term used to describe the clinical condition that results from damage to any or all tissue and/or organs in the body. The physiological response to such damage, often stemming from loss of blood volume or other trauma, results in a cascade of events that can lead to multiple organ system failure and, in some cases, death. Acutely ill children are particularly vulnerable to shock because their small body size limits the amount of reserve they have, which may be insufficient to meet the physiological demands of the trauma or illness.
1. Hypovolemic shock
Hypovolemic shock generally results from diarrhea, vomiting, poor fluid intake, hemorrhage, heat stroke or burns. The leading cause of shock worldwide is hypovolemia—or loss of blood volume—due to diarrhea. Accordingly, hypovolemic shock is a major cause of infant mortality.
Clinical signs of hypovolemic shock include rapid breathing and or heart rate, abnormally low blood pressure, weak peripheral pulses, cool pale skin, increased urine output and changes in mental status.
