Brief Summary

Acute pancreatitis (AP) is a common disease whose incidence in the US reaches 35 per 100,000 population annually. Its main causes in adults are gallstone migration into the common bile duct and alcohol abuse. Approximately 80% of patients with AP will develop a mild disease for which the management is mainly conservative. However 20% will develop a severe form, which is known to be associated with the development of local complications, such as pancreatic and peripancreatic necrosis, pseudocysts, and systemic complications, such as adult respiratory distress syndrome or renal failure. In the severe form of AP the mortality rate can reach 17% mainly due to multiple organ failure and pancreatic necrosis. In particular, pancreatic necrosis is associated with a death rate of up to 40%.

Epidural anesthesia (EA) is widely used to induce analgesia in the perioperative period and has also been used to decrease pain in patients with AP. In addition, experimental studies have shown a specific beneficial effect of EA in AP, attributed to an anti-inflammatory effect of local anesthetics administered in the epidural space combined with a sympathetic nerve blockade, which redistributes splanchnic blood flow to non-perfused pancreatic regions.

To date, EA has not been adequately tested in intensive care unit (ICU) patients with severe AP, with regards to clinical outcome. The objective of our study is therefore to test the effect of EA on lung dysfunction during severe AP, as we hypothesize that EA could limit lung failure requiring invasive mechanical ventilation (MV) or the duration of invasive MV

Detailed Description

BACKGROUND:

Mild acute pancreatitis has a low mortality rate, but patients with severe acute pancreatitis (AP) are more likely to have complications and a much higher death rate. Severe pancreatic injury occurs in 20% of the patients, and 15% to 25% of these patients will not survive. The amplifying effects of inflammatory and oxidative impairment often lead to SAP-induced complications, which are often regarded as hallmarks of severe AP and herald a noted poor outcome. Since respiratory failure is the main cause of death in patients with severe AP, more work is needed for us to prevent and treat AP-associated lung dysfunction Despite recent substantial improvements in the multidisciplinary management of AP (with special emphasis on fluid therapy, intensive care management, prevention of infectious complications, nutritional support, biliary tract management or necrotizing pancreatitis management), the prognosis of severe AP remains poor in patients who develop acute respiratory failure requiring intubation and invasive respiratory support.

Animal studies suggest that epidural analgesia (EA) may decrease the severity of AP. EA is associated with sympathetic nerve blockade, which redistributes splanchnic blood flow to non-perfused pancreatic regions, and it may improve the pancreatic hypoperfusion induced by AP. EA also decreases the severity of metabolic acidosis and tissue injury, thus preventing the progression from an edematous disease to a necrotizing AP.

To date, EA has not been adequately tested in patients with severe AP as compared to conventional management, and with special emphasis on its putative beneficial ventilatory effects.

DESIGN NARRATIVE:

The purpose of this multicenter, prospective, randomized, controlled, trial is to test the effects of thoracic EA on pulmonary outcome in patients with severe AP.

After inclusion, ICU patients with severe AP will be randomized into 2 groups: a " conventional group " in which available guidelines on analgesia are applied, and an " EA " group in which patients receive thoracic EA for at least 3 days. Beyond the analgesic strategy, recent consensual guidelines on the management of severe AP are applied.

Conditions

Severe Acute Pancreatitis

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Conventional group

2 groups: a " conventional group " in which available guidelines on analgesia are applied, and an " EA " group in which patients receive thoracic EA for at least 3 days.

Group Type: OTHER

acetaminophen, nefopam, tramadol, opidoids

Intervention Type: OTHER

Conventional analgesia will include enteral and/or parental administration of usual analgesics, ranging from step 1 to step 3 drugs according to WHO classification (including acetaminophen, nefopam, tramadol, opidoids). The route, dose and frequency of analgesics administrations will be based on participating ICUs protocols.

EA group (Epidural anesthesia )

2 groups: a " conventional group " in which available guidelines on analgesia are applied, and an " EA " group in which patients receive thoracic EA for at least 3 days.

Group Type: EXPERIMENTAL

ropivacaine and sufentanil

Intervention Type: OTHER

Thoracic epidural analgesia will be performed using ropivacaine (2 mg/ml), sufentanil (0.5 microg/ml) administered through a patient-controlled deviced (PCEA : patient-controlled epidural analgesia). PCEA parameters will be fixed as follows : continuous administration of 5 to 15 ml/h and bolus of 3 to 10 ml every 10 minutes. Iterative epidural administration of clonidine (1 mckg/kg) will be allowed to achieve analgesia goals.
