【 摘 要 】

The objective of this paper was to develop a clinically relevant abdominal compartment syndrome experimental model, as a single insult and as a second insult flowing hemorrhagic shock. In the single insult model, Sprague-Dawley male-rats are anesthetized, invasively monitored (central venous pressure and mean arterial pressure), and mechanically ventilated during intraperitoneal injection of air to provoke the abdominal compartment syndrome (25 mmHg) for 60 minutes. In the two insult model, Sprague-Dawley male-rats are anesthetized, invasively monitored (mean arterial pressure) and bled to a mean arterial pressure of 30 mmHg for 45 minutes. Fluid resuscitation is accomplished by infusing 0.9% sodium chloride solution (0.9% NaCl) 33.2 ml/kg plus 75% of shed blood volume. During this phase a laparotomy is performed. Two hours after the beginning of the hemorrhagic shock phase the animals are anesthetized, intubated (orotracheal), mechanically ventilated (mean arterial pressure), and the intra-abdominal pressure is increased to 25 mmHg for 60 minutes, as a second insult. A 0.9% NaCl solution is infused during this phase (45 ml/kg/h). Hemorrhagic shock and the abdominal compartment syndrome behave as clinically relevant additive insults.
