Surgical decompression is the last but the most effective way to decrease IAP and should not be postponed too late if patient has developed ACS [10]. Patients with acute pancreatitis have a considerable risk for developing secondary infections including bacteremia, pneumonia and infection of pancreatic or peripancreatic necrosis. Extrapancreatic infections occur predominantly during the first week of illness, whereas pancreatic necrosis check details becomes infected later [11]. The mortality is very high in patients with persistent organ failure complicated with infected pancreatic necrosis [12]. Development of bacteremia and infected pancreatic necrosis are associated with MODS. Intestinal dysfunction

plays an important role and bacterial translocation from intestine is considered the main mechanism of infection. Impaired host response systems may also predispose to clinical infections. Early enteral nutrition has been shown to reduce systemic infections [13], whereas the results from randomized trials with prophylactic antibiotics have been inconclusive [14]. Surgery is considered necessary for adequate source control when pancreatic or peripancreatic infection develops. However, because surgery for pancreatic necrosis within

the first 2–3 weeks from disease onset is associated with high mortality, surgery should be postponed as late as possible [15]. Sometimes percutaneous drainage of fluid from infected acute necrotic collection may be helpful and is preferable first-line treatment for infected pancreatic necrosis during selleck screening library Clomifene the first three weeks of illness [16]. Fluid resuscitation and abdominal compartment syndrome Aggressive fluid therapy during the early phase of acute pancreatitis has been traditionally the cornerstone of treatment [17]. The rationale of fluid therapy is to

correct hypovolemia caused by third space fluid loss. High admission hematocrit (above normal reference limits) may serve as a marker of hemoconcentration, and it is present up to 60% of patients who develop organ failure [18], but the marker is too unspecific for predictive purposes [19]. Fluid resuscitation decreases hematocrit, which could be used as resuscitation end-point. Too aggressive resuscitation may lead to inappropriate hemodilution and very low hematocrit values (<30%) may be harmful for the patients by increasing the risk of sepsis and death [20]. Moreover, excess volume loading may increase IAP and lead to development of intra-abdominal hypertension (IAH) and abdominal compartment syndrome [21]. In patients with acute pancreatitis, hematocrit and central venous pressure as resuscitation end-points are poor indicators of volume depletion [22]. Urine output (≥0.5 ml/kg/h) may serve as another resuscitation end-point, but other modalities are needed for volume management if oliguria persists after initial volume loading.
