AbstractSevere burns represent a devastating injury that induces profound systemic inflammation requiring large volumes of resuscitative fluids. The consequent massive swelling and peritoneal ascites raises intraabdominal pressures (IAP) to supraphysiologic levels commensurate with intraabdominal hypertension (IAH) and with the abdominal compartment syndrome (ACS) if consistently associated with IAP >20 mmHg and associated with new organ failure. Severe burn injuries are an example of the secondary ACS (secondary ACS), wherein there has been no primary inciting intraperitoneal injury, yet severe IAH/ACS develops, setting the stage for progressive multiorgan dysfunction. These definitions along with practice management guidelines have recently been promulgated by the World Society of the Abdominal Compartment Syndrome (WSACS) in an effort to standardize terminology and communication regarding IAH/ACS in critical care. It is currently unknown whether these syndromes are iatrogenic consequences of excessive or poorly managed fluid resuscitation or unavoidable sequelae of the primary injury. It occurs frequently with burns of >60% body surface area, especially with associated inhalational injury, delayed resuscitation, and abdominal wall injuries. IAH/ACS is often a hyperacute phenomenon that occurs within the first hours of admission and thereafter with any complication requiring aggressive fluid resuscitation. Despite a number of noninvasive management strategies, interventions such as percutaneous peritoneal drainage and, ultimately, decompressive laparotomy are often required once the ACS is established. Whether novel resuscitation strategies can avoid or minimize IAH/ACS is unproven at present and requires further study. Truly understanding postburn ACS may require further insights into the basic mechanisms of injury and resuscitation.
