AbstractThe definitions of intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are not uniform despite the increasing awareness of IAH/ACS in burn patients. A short survey including definitions, resuscitation protocols, and monitoring practices was sent to every physician listed in the American Burn Association Directory. Thirty-two of 123 (26%) surveys were returned; 22 (69%) were from verified burn centers. Survey respondents said that bladder pressure indicating IAH is 19.6 mm Hg (range 12-30) and ACS is 25.9 mm Hg (range 15-40). Fifteen percentage of those responding do not include clinical sequellae in their definition of ACS. Bladder pressure is not routinely measured by 22 (69%) burn physicians, and staff at 17 centers (53%) wait until the abdomen is tense to measure abdominal pressure. Tense abdomen, along with elevated peak inspiratory pressures (PIP), is used in most centers (94%) to determine IAH/ACS, followed by oliguria (88%), and difficulty ventilating (78%). Resuscitation formulae used are primarily the Parkland/modified Parkland in 24 (75%) burn centers. Criteria for abdominal decompression is based on bladder pressures alone in 25 centers (78%); 16/32 (50%) use PIP, and 10/32 (31%) staff use other criteria including organ dysfunction or increased lactate. Eleven physicians (34%) advocate percutaneous decompression before decompressive laparotomy. Although most United States burn physicians define ACS as >or=25 mm Hg along with physiologic compromise, bladder pressure is routinely measured by only 31% of burn physicians. Most burn staff do not differentiate between IAH and ACS. Consensus definitions of IAH/ACS are necessary for burn care practitioners to compare research studies and discuss outcomes. Concise definitions will promote understanding of the pathophysiological processes involved and allow us to develop data-driven patient care protocols.
