    PurposeTo the best of our knowledge, in the literature, there is no data regarding clinical utility of the abdominal perfusion pressure (APP) in critically ill children. Thus, in the present study, we aimed to investigate the clinical utility of APP in predicting of survival in critically ill children with IAH.DesignA prospective cohort study of patients between 1 month to 18 years who had risk for intra-abdominal hypertension from June 2013 to January 2014.SettingPediatric intensive care unit (PICU) at a tertiary university hospital.PatientsThirty-five (16 female) PICU patients who had risk for the development of IAH were included. Serial intraabdominal pressure (IAP) and mean arterial pressure (MAP) measurements were performed. Abdominal perfusion pressure was calculated using the formula (MAP-IAP).Measurements And Main ResultsOverall mortality rate was 49% (n = 17). The mortality rate in patients with IAP mean ≥10 mmHg (n = 27, 77%) was 55% (n = 15), while 53% (n = 16) in patients with IAP max ≥10 mmHg (n = 30, 86%) and 47% (n = 7) in patients with IAP min ≥ 10 mmHg (n = 15, 43%). Overall mean APP was 58 ± 20 mmHg. Logistic regression analysis revealed that decrease in minAPP was associated with increased risk for mortality (Odds ratio for each 1 mmHg decrease in APP was 1.052 [CI 95%, 1.006-1.100], p < 0.05). ROC curve analysis revealed that, in predicting mortality, area under curve for minAPP was 0.765. The optimal cut-off point for APP was obtained as 53 mmHg with the 77.8% sensitivity and 70.6% specificity using the IU method.ConclusionsOur findings showed that APP seems to be a useful tool in predicting mortality. Interventions to improve APP may be associated with better outcomes in critically ill PICU patients.Level Of EvidenceLevel II.Type Of StudyDiagnostic.Copyright © 2018 Elsevier Inc.
