  1. Presented as frequencies, mean and standard deviations
  2. aMajority of the patients were male 70.8%
  3. bThe mean age of the study population was 37.2 years
  4. c The amount of intravenous fluids administered over 24 h as recorded in input–output chart
  5. d The fluid balance was derived from the difference of the total amount of fluids administered(sum of IV fluids and enteral and parenteral feeds) and the output(urine output plus 700 ml of estimated insensible fluid losses)
  6. e Peak airway pressure (PAP) in cm of H20 as displayed on the ventilator
  7. f White cell count (WBC) one of the parameters from total blood count profile others considered being haemoglobin and platelets count
  8. gVentilation mode as set by the intensive care team. Biphasic positive airway pressure (Bipap), Continuous airway pressure (CPAP), Synchronised intermittent mandatory ventilation(SIMV)
  9. hOf the 113 patients analysed,76(67.3%) had intraabdominal pressure (IAH) when the mean intraabdominal pressure in 24 h was considered. This number rose to 81(71.7%) when the maximal (highest reading in 24 h) is considered. The IAH was categorised in severity from most mild (grade 0, no IAH) to most severe level (grade 4) based on the intrabadominal pressure readings in mm Hg after conversion from cm of H20
  10. iThe patients were categorised based on diagnosis at admission into those whose primary pathology was in the abdominal pelvic region and the others to be able to generate data on primary(of those with adominopelvic conditions) and secondary(those with other [non abdominopelvic] conditions) IAH and ACS.When mean IAP is considered, of those who developed IAH, 60.5% had non abdominopelvic conditions therefore secondary IAH. This number is similar when maximal IAP is considered
