Abstract OBJECTIVE: To study risk factors for the occurrence of intra-abdominal hypertension (IAH) in children with sepsis. METHODS: A nest case-control study was employed. According to intra-abdominal pressures (IAP) measured by cystometry, 119 children with sepsis were classified into normal IAP (control, n=80) and IAH groups (n=39). Risk factors for the occurrence of IAH were investigated by monovariable and multivariable logistic regression analysis. RESULTS: Monovariable analysis showed that there were significant differences in pediatric critical illness score (PCIS), procalcitonin (PCT) level, PaCO2, blood lactate level, rates of intestinal or intra-abdominal infection, ascites, gastrointestinal dysfunction, mechanical ventilation, shock and multiple organ dysfunction syndrome (MODS) between the IAH and control groups (P<0.05). Multivariable logistic regression analysis demonstrated that decreased PCIS, MODS, shock, gastrointestinal dysfunction and ascites were major risk factors for the occurrence of IAH. CONCLUSIONS: Children with sepsis who have decreased PCIS, MODS, shock, gastrointestinal dysfunction and ascites are at risk for the occurrence of IAH.
