ABSTRACT
Intra-abdominal hypertension (IAH) is recognized to be associated with adverse outcomes in critically ill patients. Etiologic factors for IAH can be divided into three categories: medical, posttraumatic, and surgical/postoperative. No studies have been performed on patients who underwent nonelective surgery, so our aim was to determine prospectively the incidence of IAH among these patients during their intensive care stay to correlate intra-abdominal pressure (IAP) and other parameters. Abdominal pressure was recorded twice daily with the standard method. The study group enrolled 22 patients who underwent an abdominal operation that met urgency criteria and with a postoperative intensive care unit (ICU) stay of at least 48 hours. Several serum and clinical parameters were studied for the first 5 postoperative days as well as during ICU and hospital stay as well as monitored hospital mortality. Our results demonstrated that mortality was definitely higher among patients who developed IAH compared with non-IAH patients. Our results highlighted that a strong correlation existed between increasing values of IAP and worsening serum creatinine and PaO2/FiO2 quotient among patients who underwent nonelective surgery.
