Four patients are described in whom massive abdominal distension after
laparotomy led to increased airway and central venous pressure and se
verely reduced urine output. All cases were associated with massive fl
uid resuscitation and operative findings were a grossly oedematous bow
el with free fluid under pressure in the abdomen. These findings are c
onsistent with the diagnosis of intra-abdominal compartment syndrome.
In 1 case trauma was remote from the abdomen indicating that abdominal
surgery or trauma may not be a prerequisite for the development of th
e condition. Recognition of the features of the condition is essential
as it can only be treated by decompression of the abdominal contents.
