“…Indirect measurements of IAP are position dependent and may not correlate well with the IAP except in the supine position where the mean increment in bladder pressure reflected most closely the IAP [ 3 ]. Although not widely accepted, the presence of air-bubbles in the fluid-filled system may partly account for measurement inaccuracy leading to over- or under-estimation [ 5 , 14 ]. In our study, all pressure measurements were performed with the patients lying in supine position and the pressure transducers zero reference level placed at the symphysis pubis.…”

BackgroundIntra-abdominal pressure (IAP) can be measured by several indirect methods; however, the urinary bladder is largely preferred. The aim of this study was to compare intra-bladder pressure (IBP) at different levels of IAPs and assess its reliability as an indirect method for IAP measurement.MethodsWe compared IBP with IAP in twenty-one patients undergoing laparoscopic cholecystectomy under general anesthesia. Measurements were recorded at increasing levels of insufflation pressures to approximately 22 mmHg. Pearson’s correlation coefficient was calculated to establish the relationship between the two pressure measurements and Bland-Altman analysis was used to assess the limits of agreement between the two methods of measurements.ResultsThe urinary bladder pressures reflected well the pressures in the abdominal cavity. Pearson correlation coefficient showed a good correlation between the two measurement techniques (r = 0.966, p < 0.0001) and Bland-Altman analysis indicated that the 95% limits of agreement between the two methods ranged from − 2.83 to 2.64. This range is accepted both clinically and according to the recommendations of the World Society of Abdominal Compartment Syndrome (WSACS).ConclusionOur study showed that IBP measurement is a simple, minimally invasive method that may reliably estimates IAP in patients placed in supine position. Measurements for pressures higher than 12 mmHg may be less reliable. When applied clinically, this should alert the clinician to take safety measures to avoid abdominal compartment syndrome (ACS).

“…Iberti et al 15 , 82 introduced a modification that had some of the short-comings of the previous method with the advantage that it is simpler, less time-consuming and needed less manipulation. About a decade later, Cheatham and Safcsak 83 introduced a modification that was revised by Malbrain 84 which serves as the current standard for the intra-vesical technique. Using a three-way Foley’s catheter, investigators in Australia 85 have shown that a continuous measurement of IAP is possible and of practical advantage in critically ill patients.…”

The term abdominal compartment syndrome (ACS) describes the clinical manifestations of the pathologic elevation of the intra-abdominal pressure (IAP). When the IAP exceeds 12 mm Hg it is referred to as intra-abdominal hypertension (IAH) while ACS generally sets in at an IAP in excess of 20 mm Hg. This syndrome is most commonly observed in the setting of severe abdominal trauma and in the aftermath of major abdominal operations. ACS affects mainly the respiratory, cardiovascular, renal, gastrointestinal and the central nervous systems. Fundamental to the development of ACS are the obstruction of venous return to the heart via the inferior vena cava and the splinting of the diaphragm due to elevated IAP. Preventing ACS by the identification of patients at risk and early diagnosis is paramount to its successful management. To this end a high index of suspicion is sine qua non. The management of established ACS requires clinical astuteness and decisiveness with a readily available and generous team support. The purpose of this review is to enhance awareness among clinicians about a subtle condition with a devastating impact on morbidity and mortality if undiagnosed.
