Thoracic Epidural Analgesia for Acute Pancreatitis With Early Organ Dysfunction (TEA-APOD)

19 luglio 2026 aggiornato da: Xingui Dai, First People's Hospital of Chenzhou

Effect of Thoracic Epidural Analgesia on Organ Support Burden in Patients With Acute Pancreatitis and Early Organ Dysfunction: A Single-Center Randomized Controlled Trial

Acute pancreatitis may cause early respiratory, cardiovascular, or renal dysfunction and may require intensive care and organ support. Thoracic epidural analgesia may improve pain control, reduce systemic opioid exposure, and facilitate gastrointestinal recovery; however, its effect on overall organ support burden remains uncertain.

This is a single-center, prospective, randomized, open-label, parallel-group clinical trial. A total of 150 adults with acute pancreatitis within 72 hours of symptom onset and early respiratory, cardiovascular, or renal dysfunction will be randomized in a 1:1 ratio to receive either ropivacaine-only thoracic epidural analgesia plus standard care or standardized conventional analgesia plus standard care.

The primary outcome is alive and organ support-free days through day 14 after randomization. Secondary and exploratory outcomes include alive and organ support-free days through day 28, organ dysfunction-free days, ventilator-free days, renal replacement therapy-free days, vasoactive drug-free days, 28-day mortality, pain scores, systemic opioid exposure, gastrointestinal and nutritional outcomes, intra-abdominal pressure, inflammatory markers, complications, length of stay, hospital costs, and adverse events related to thoracic epidural analgesia.

Descrizione

Inclusion Criteria:

Inclusion Criteria:

  1. Age 18 to 75 years, inclusive.
  2. Diagnosis of acute pancreatitis based on at least two of the following three criteria: typical acute upper abdominal pain; serum amylase and/or lipase at least three times the upper limit of normal; or imaging findings consistent with acute pancreatitis.
  3. Time from symptom onset to randomization of 72 hours or less.
  4. Early respiratory, cardiovascular, or renal organ dysfunction, defined as a SOFA-2 subscore of 2 or greater in at least one of these three organ systems, requiring ICU admission for continuous monitoring and treatment. The SOFA-2 score will be calculated using the worst available values during the 24 hours before randomization; for participants admitted to the ICU for less than 24 hours, values available since ICU admission will be used. The organ dysfunction must be newly developed or clearly worsened from the participant's previous stable baseline.
  5. Written informed consent provided by the participant or legally authorized representative.

Exclusion Criteria:

  1. Pregnancy or lactation.
  2. Chronic pancreatitis or acute pancreatitis associated with a pancreatic tumor.
  3. Prior retroperitoneal drainage, endoscopic drainage, surgical necrosectomy, or other invasive intervention before randomization that may substantially alter the natural course of the disease.
  4. Invasive mechanical ventilation before randomization.
  5. Any contraindication to thoracic epidural analgesia, including allergy to local anesthetics; infection at the puncture site; epidural abscess or central nervous system infection; severe spinal deformity or prior spinal surgery that prevents catheterization; intracranial hypertension or severe central nervous system disease; uncorrected coagulation disorder; or anticoagulant or antiplatelet therapy that does not meet neuraxial safety requirements.
  6. Uncorrected shock or persistent hemodynamic instability despite adequate fluid resuscitation and vasoactive drug support.
  7. End-stage renal disease requiring maintenance dialysis before randomization.
  8. Participation in another interventional clinical study within the previous 3 months.
  9. Any other condition that, in the investigator's judgment, makes the participant unsuitable for enrollment.

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Comparatore attivo: Conventional Analgesia Group
Participants in this group will receive conventional analgesia and standard treatment for severe acute pancreatitis. Conventional analgesia may include non-steroidal anti-inflammatory drugs, acetaminophen, tramadol, fentanyl, sufentanil, oxycodone, hydromorphone, morphine, dexmedetomidine, or other analgesic and sedative medications according to clinical judgment. Analgesic drugs, doses, routes, duration of administration, rescue analgesia, sedative use, and opioid consumption will be recorded.
Conventional analgesia will be administered according to institutional practice and the participant's clinical condition. The analgesic target is an NRS score of 3 or less in conscious and communicative participants, or a CPOT score of 2 or less in non-communicative critically ill participants. Analgesic drugs, doses, routes, duration of administration, rescue analgesia, sedative use, and opioid consumption will be recorded.

  • Systemic analgesia
Sperimentale: Thoracic Epidural Analgesia Group

Participants will receive standard treatment for acute pancreatitis plus thoracic epidural analgesia using ropivacaine alone. After initial fluid resuscitation, blood pressure stabilization, and safety assessment, thoracic epidural analgesia will be initiated as soon as possible after randomization, preferably within 6 hours, no later than 24 hours after randomization, and before 72 hours from symptom onset.

Epidural catheterization will be performed at T8-T11, preferably T9-T10 or T10-T11, by an investigator qualified to perform neuraxial procedures and trained in the study protocol. After a negative test dose of 1% lidocaine 3 mL, a loading dose of 0.2% ropivacaine 5-10 mL will be administered, followed by continuous infusion of 0.2% ropivacaine at 6-8 mL/hour. The target sensory block is T6-T12 and should cover the main upper abdominal pain area.

Thoracic epidural analgesia will generally continue for 5 days or until ICU discharge if earlier. It may be extended to a maximum of 7

Thoracic epidural block will be performed by an investigator qualified to perform neuraxial procedures and trained in the study protocol. Before catheterization, the clinical team will assess hemodynamic status, coagulation function, antithrombotic medication use, infection risk, respiratory status, and baseline neurological status. The puncture level will be selected according to the participant's condition and operator assessment, generally within the T7-T11 range to cover upper abdominal pain.

After thoracic epidural catheter placement, a test dose of 1%-1.5% lidocaine 3 mL will be administered to exclude intrathecal or intravascular catheter placement. If the test dose is negative, a loading dose of ropivacaine may be administered, followed by continuous thoracic epidural infusion of ropivacaine alone.

No epidural opioid, including sufentanil, fentanyl, or morphine, will be added to the epidural infusion in this study.

Misura Descrizione
Lasso di tempo
Alive and Organ Support-Free Days Through Day 14 (AOSFD-14)
Lasso di tempo: From randomization through day 14
Alive organ support-free days to day 14 is defined as the number of days from randomization to day 14 during which the participant is alive and free of ICU-level organ support. ICU-level organ support includes invasive mechanical ventilation, noninvasive ventilation, continuous infusion of vasoactive or inotropic drugs, and renal replacement therapy. A day will be counted as organ support-free only if the participant is alive and does not receive any of these organ support treatments on that day. Participants who die within 14 days after randomization will be assigned 0 alive organ support-free days.

Pain Score
Lasso di tempo: Baseline, 3-6 hours after intervention initiation, and days 1, 3, 5, and 7

Pain intensity will be assessed using the Numeric Rating Scale (NRS) in conscious and communicative participants, or the Critical-Care Pain Observation Tool (CPOT) in non-communicative critically ill participants.

The NRS is an 11-point scale ranging from 0 (no pain) to 10 (worst possible pain). The CPOT ranges from 0 (no pain) to 8 (worst possible pain). For both scales, higher scores indicate worse pain control (worse outcome).

Baseline, 3-6 hours after intervention initiation, and days 1, 3, 5, and 7
