RESUMO
<p><b>OBJECTIVE</b>To investigate the efficacy of pressure reduction by peritoneal catheterization in patients with malignant ascites-induced abdominal compartment syndrome (ACS).</p><p><b>METHODS</b>Clinical data of 29 patients with malignant ascites-induced ACS from October 2002 to October 2008 were analyzed retrospectively. Intra-abdominal pressure (IAP) was reduced by peritoneal catheterization. Changes of intra-abdominal pressure and ascites volume were observed during treatment. Clinical signs and urinary volume were monitored.</p><p><b>RESULTS</b>IAP was less than 25 cm H(2)O in 2 cases, 25 to 35 cm H(2)O in 21 cases, more than 35 cm H(2)O in 6 cases. IAP decreased significantly after drainage of 1000 to 1500 ml of ascites, then IAP curve leveled off. With all the ascites drained, IAP maintained at 11 to 12 cm H(2)O and at 6 to 8 cm H(2)O after 24 hours. Blood pressure was stable without significant changes before and after IAP reduction (P>0.05). The breathing rate and heart rate were improved, and 24 h urinary volume increased significantly after IAP reduction (P<0.01).</p><p><b>CONCLUSION</b>Early peritoneal catheterization can improve the cardiac, pulmonary, and renal function in malignant ascites-induced ACS.</p>
