About
Although many measurement techniques have been tried for intra-abdominal pressure, the Kron technique is currently the gold standard method. However, the search for other methods continues due to its long application time, the need for more equipment, and impracticality. Consequently, the investigators sought to investigate a quicker and more accessible method suitable for successful intra-abdominal pressure measurement in the emergency department. This study aimed to compare intra-abdominal pressure measurements in patients diagnosed with ileus using a digital manometer and the Kron Technique.
Full description
Before the start of the study, the Kron Technique and IAP measurement with a digital manometer were demonstrated both didactically and practically to 4th year Emergency Medicine residents. It was ensured that any two of these residents were continuously present on the monthly duty roster. When a patient who met the inclusion criteria presented to the emergency department, the residents were separately invited to the bedside for measurements by the attending physician without each other's knowledge. After the attending physician obtained information about the patient, the exclusion criteria were evaluated. After the patient was deemed eligible, the attending physician explained the application and the study to the patient in detail. Informed consent was obtained from the patients both verbally and in written. Demographic information (age, gender) and medical history were recorded.
Measurements were performed with the patient in the supine position. A transurethral Foley catheter (16 Fr) was inserted by the attending physician under sterile conditions. First, IAP was measured using the 'Kron technique.' The connection hose of the urine collection container was attached to the Foley catheter. The hose was clamped after the urine in the bladder was completely emptied. A sterile three-way tap was attached to the urine sample port in the connection hose. From the three-way tap, 25 ml of sterile saline was injected into the bladder with a syringe. Subsequently, one end of the transducer interconnection cable was connected to the three-way tap, and the other end was connected to the bedside monitor (GE B40 V3 bedside monitor, Germany). Subsequently, pressure adjustments were reset on the monitor, and IAP was recorded in mmHg. After this measurement, a digital manometer was used. This measurement was performed by the second resident. The "Compass Lumbar Puncture Pressure Transducer" (Mirador Biomedical, Seattle, WA, USA) was used as a digital manometer (Figure 2). 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. The IAP measurement value recorded in cmH2O was converted to mmHg using the equation "1 cmH2O = 0.7355 mmHg." During the measurements, the patient's treatment plan was not interrupted.
