OBJECTIVE: To develop diagnostic criteria of multiple organ dysfunction syndrome (MODS) by a prospective and multi-center clinical investigation. METHODS: The data of 1087 MODS cases obtained from ICU of 37 hospitals from March 2002 to January 2005 in 11 provinces in China were analyzed in order to derive the diagnostic criteria of MODS. RESULTS: This MODS diagnostic criteria involved 7 organs. To diagnose MODS, the original cause of MODS should be identified, then there should be two or more organs showing signs of dysfunction. The criteria for organ dysfunction were as follows. (1) Cardiovascular system: SBP < 90 mm Hg (1 mm Hg = 0.133 kPa), MAP < 70 mm Hg, signs of shock, ventricular tachycardia, ventricular fibrillation, or myocardial infarction; (2) Respiratory system: oxygenation index < 300 mm Hg; (3) Nervous system: indifference, restlessness, lethargy, light coma, or deep coma, Glasgow score < or = 14; (4) Blood system: PLT < 100 x 10(9)/L; CT, APTT, and PT prolonged or shortened; positive plasma protamine paracoagulation; (5) Liver: TBIL > 20. 5 micromol/L, ALB < 28 g/L; (6) Kidney: Cr > 123.8 micromol/L, urinary volume < 500 ml/24 h; (7) Gastro-intestine: bowel sounds decreased or disappeared; retention in the stomach, or positive occult blood feces with dark stools or haematemesis; intraabdominal pressure (intravesical pressure) > or = 11 cm H2O (1 cm H2O = 0.098 kPa). Any organ function met with one of the above conditions was considered to have dysfunction. CONCLUSIONS: This diagnostic criterion of multiple organ dysfunction syndrome has been developed by this research, but it needs to accumulate experience by clinical practice and to revise the diagnosis criteria.
