The Impact of Intra-Abdominal Pressure on Mortality and Morbidity in Patients Undergoing Open-Heart Surgery

This prospective observational study evaluated whether increased intra-abdominal pressure, meaning increased pressure inside the abdomen, is associated with postoperative complications and mortality in adults undergoing elective open-heart surgery with cardiopulmonary bypass. Intra-abdominal pressure was measured through the urinary bladder at three time points: after anesthesia induction, after closure of the sternum, and two hours after admission to the intensive care unit. Participants with an intra-abdominal pressure of 12 mmHg or higher at any measurement were compared with those whose pressure remained below 12 mmHg. The study examined postoperative recovery outcomes, including time to extubation, length of stay in the intensive care unit and hospital, postoperative complications, and mortality. It also aimed to identify perioperative factors associated with increased intra-abdominal pressure. No study-specific treatment or intervention was assigned, and all patients received standard perioperative care.

Intra-abdominal Pressure (IAP) During PFA Treatment of A-fib/ A-Flutter

The purpose of this study is to investigate the intra-abdominal pressure utilizing the Accuryn monitoring system during pulsed field ablation procedures in the electrophysiology lab compared to the type of anesthetic utilized.

Intra-gastrointestinal Monitoring Device (PressureDOT®) and Centurion IAP Monitoring Device Comparison Study: Pivotal Study of Safety and Performance.

The proposed clinical study protocol is intended to establish the safety, utility, and reliability of using a pressure-sensing capsule present in a patient's gastrointestinal tract for monitoring intraabdominal pressure (IAP). Monitoring IAP in critically ill patients is common in patients admitted to the ICU following a wide variety of surgical interventions. It has been reported that approximately 50% of critically ill patients will develop intraabdominal hypertension (IAH; defined as an IAP \>12 mmHg) while in the ICU, which can be life-threatening due to complications resulting from organ dysfunction, organ failure, impaired ventilation and hemodynamic instability. When IAH is persistent and elevated above 20 mmHg the condition is identified as "Abdominal Compartment Syndrome (ACS)", which necessitates close monitoring of patients with IAH in order to reduce the development of ACS. IAP measurements based on technologies employing the bladder, gastric, inferior vena cava, rectal, vaginal and direct intraperitoneal placements have been reported for assessing IAP. However, the gold standard method for monitoring IAP is the use of an intravesical (bladder) Foley catheter manometric technique. PressureDOT® (Dotspace Inc.) is the investigational pressure-sensing capsule that will be assessed in a parallel device clinical study protocol performed in the same patient.
