Objective: To describe computed tomographic (CT) features of intra-abdominal hypertension (IAH) in 3 dogs with abdominal distension. Case Summary: Three dogs with anorexia, distended abdomen, or labored breathing were presented for CT imaging. All 3 dogs were premedicated with IV butorphanol (0.2 mg/kg). A Foley urinary catheter was aseptically placed and the transvesical technique was used to obtain intraabdominal pressure (IAP). The IAP measurements were obtained with the dogs in a standing position after a stabilization period of 5 minutes. The mean IAP values for each of the 3 dogs were 26.0, 12.0, and 13.0 mm Hg. Anesthesia was induced with IV propofol (2.0-4.0 mg/kg, to effect) in all 3 dogs and maintained with sevoflurane in 2 dogs. Compression of the caudal vena cava and elevation of the diaphragm were observed in all 3 dogs, whereas renal compression and the extension of peritoneal fluid to the vaginal canal and cavity were seen in the dog with the highest IAP. New or Unique Information Provided: Compression of the caudal vena cava, direct renal compression, and the extension of peritoneal fluid into the vaginal canal and vaginal cavity are consistent with a diagnosis of IAH. Measurement of IAP and detection of these CT features should alert clinicians to the possible presence of IAH in veterinary patients.

“…A sustained increase in intra-abdominal pressure (IAP) can cause intraabdominal hypertension (IAH) and abdominal compartment syndrome (ACS), which contributes significantly to increased morbidity and mortality in critically ill people. [1][2][3][4] The increased pressure within the abdominal cavity can adversely affect normal perfusion and function in the surrounding tissues, 5 and eventually this process can lead to physiologic dysfunction and multiple organ failure. 6 In veterinary medicine, there have been a few reports of IAH and ACS having multiple negative systemic effects.…”

Objective To evaluate the effect of intra‐abdominal pressure (IAP) on plasma exogenous creatinine clearance in both conscious and anesthetized dog models using a balloon technique to generate intra‐abdominal hypertension. Design Prospective, cross‐over, experimental study. Setting University‐based small animal research facility. Animals Six healthy male Beagle dogs. Interventions A balloon device comprising a Foley urinary catheter and latex balloon was placed in the intra‐abdominal cavity. Plasma exogenous creatinine clearance was compared after intravenous administration of exogenous creatinine solution at 80 mg/kg under 4 different treatment conditions as follows: control and IAP levels of 25 mm Hg in conscious dogs and control and IAP levels of 25 mm Hg in anesthetized dogs (CC, C25, AC, and A25, respectively). Samples were obtained before (T0) and 10, 20, 30, 60, 90, 120, 240, 360, 480, and 600 min after administration of creatinine in all treatment groups. Measurements and main results There were no significant differences in plasma creatinine concentration for CC, AC, and C25 during the treatment period. However, in the A25 treatment condition, the plasma creatinine concentration increased significantly at 10, 20, 30, 60, 90, and 120 min after administration of creatinine (P < 0.05). Plasma creatinine clearances were 5.0 ± 0.5, 4.7 ± 1.2, 5.5 ± 0.9, and 2.5 ± 0.5 mL/kg/min for 600 min (CC, AC, C25, and A25, respectively). In the A25 treatment condition, the plasma exogenous creatinine clearance decreased significantly to 50%, 47%, and 55% of that under control conditions (CC, AC, and C25, respectively). After decompression of the abdomen, plasma creatinine concentrations declined rapidly and returned to basal concentrations. Conclusions Intra‐abdominal hypertension under general anesthesia could cause renal hypoperfusion. Timely decompression may improve the outcome of acutely increased IAP when surgery and/or general anesthesia is required in canine patients.

An acute rise of intra-abdominal pressure (IAP) leads to intra-abdominal hypertension (IAH), which if severe and left untreated can be life threatening (Hoareau & Mellema, 2015;Nielsen & Whelan, 2012;Parsak et al., 2008). IAH is defined as a constant elevation of IAP of more than 12 mmHg (Hunter & Damani, 2004). IAH is clinically important because it might lead to impairment of haemodynamic stability, organ perfusion and pulmonary function (Hunter
