Digital Manometry for Intra-Abdominal Pressure Measurement in Ileus

"The Compass Lumbar Puncture Pressure Transducer (Mirador Biomedical, Seattle, WA, USA) was used as a digital manometer. After the bladder was completely emptied, the catheter was clamped again. 25 cc of sterile saline was injected into the bladder through the urine sample port. The digital manometer was connected to the urine sample port. The IAP value in cmH2O on the digital screen of the device was noted."
