Validation of Intraabdominal Pressure (IAP) Study
About this study
Objectives:
1. To compare the IAP measured directly via a peritoneal catheter with intra-vesical methods using 3ml of saline.
2. To test whether using 3ml for indirect IAP measurements accurately measures IAP in patients with intra-abdominal hypertension or ACS.
3. To determine if there is a correlation between tissue saturations in the brain, kidney and gut with IAP and abdominal perfusion pressure (APP).
4. To determine the threshold IAP and APP at which there is a decline in tissue oxygen saturation in the brain, kidney and gut during variations in IAP.
Inclusion criteria
30 Children < 18 years with peritoneal drains
Exclusion criteria
Patients with contraindications for placement of a urethral catheter e.g. urethral trauma, patients with recent bladder surgery and premature babies less than 36 weeks gestation.
