About this study

This randomized clinical trial compares the hemodynamic effects of general anesthesia versus combined general anesthesia (thoracic epidural) in patients undergoing pancreatoduodenectomy. The primary aim is to assess the incidence of intraoperative hypotension and related adverse events. Secondary outcomes includes vasopressor requirements, transfusion needs, postoperative complications, intensive care unit admission, hospital length of stay, and mortality.

Read the detailed description

Pancreatoduodenectomy is a major surgical procedure associated with significant hemodynamic challenges. Thoracic epidural anesthesia provides effective analgesia and may attenuate the surgical stress response, its intraoperative use has been associated with increased risk of hypotension and higher vasopressor requirements.

This randomized clinical trial aims to evaluate intraoperative hemodynamic changes in patients undergoing elective pancreatoduodenectomy managed with either general anesthesia or combined general anesthesia (thoracic epidural). A total of 206 patients will be enrolled at the "National Institute of Medical Sciences and Nutrition Salvador Zubirán". Patients will be randomized into two groups: one receiving general anesthesia and the other receiving combined general anesthesia (thoracic epidural).

Randomization will be performed using the REDCap platform with a simple 1:1 allocation ratio. Each patient's group assignment will be generated automatically by REDCap at the time of enrollment to ensure allocation concealment.

An independent observer, blinded to the anesthetic technique, will monitor and record episodes of hypotension throughout the perioperative period. The principal investigator will be blinded to group assignment.

Secondary outcomes include intraoperative vasopressor use, estimated blood loss, transfusion requirements, postoperative complications (such as pancreatic fistula, anastomotic leak, hemorrhage, surgical site infection, and acute kidney injury), admission to the intensive care unit, length of stay in the ICU and hospital, and mortality.

A planned interim analysis will be conducted after the enrollment of the first 66 patients to assess the safety and feasibility of the study protocol. Based on this analysis, modifications to improve patient safety may be recommended by the research team or ethics committee.

This study will help determine the optimal anesthetic strategy to minimize hemodynamic instability and postoperative morbidity in patients undergoing pancreatoduodenectomy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • General AnesthesiaProcedure or surgery

    Patients will undergo balanced general anesthesia for pancreatoduodenectomy. Induction will include: fentanyl 4 mcg/kg, lidocaine 1 mg/kg, propofol 1.5 mg/kg, and rocuronium 0.6 mg/kg.

    Anesthesia maintenance will be achieved with sevoflurane (variable concentration as per anesthesiologist discretion) and continuous fentanyl infusion according to the attending anesthesiologist's judgment.

    No epidural catheter will be placed.

  • Combined General Anesthesia (Thoracic Epidural)Procedure or surgery

    Patients will undergo combined general anesthesia (thoracic epidural) for pancreatoduodenectomy.

    Induction will include: fentanyl 4 mcg/kg, lidocaine 1 mg/kg, propofol 1.5 mg/kg, and rocuronium 0.6 mg/kg.

    A thoracic epidural catheter will be placed at the best palpable intervertebral space between T6-T9 by the attending anesthesiologist.

    Anesthesia maintenance will include sevoflurane (variable concentration), fentanyl infusion at the anesthesiologist's discretion, and continuous infusion of 0.25% bupivacaine via the epidural catheter throughout the surgery.

Study groups in NCT06953193
Study groupRoleWhat they receive
General AnesthesiaActive comparatorPatients will receive general anesthesia for pancreatoduodenectomy. Standardized anesthetic technique will be used with induction and maintenance based on institutional protocols, including intravenous induction agents, inhalational anesthetics, and intraoperative monitoring. No epidural catheter will be placed.
Receives: Procedure: General Anesthesia
Combined General Anesthesia (Thoracic Epidural)ExperimentalPatients will receive combined general anesthesia (thoracic epidural) for pancreatoduodenectomy. Standardized general anesthesia will be administered as in the general anesthesia group, with the addition of a thoracic epidural catheter placed before induction and maintained intraoperatively with local anesthetics according to institutional protocol.
Receives: Procedure: Combined General Anesthesia (Thoracic Epidural)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of Intraoperative Hypotension

    Defined as the occurrence of any mean arterial pressure (MAP) <65 mmHg during the intraoperative period, measured continuously with an invasive arterial line or intermittently with a non-invasive blood pressure monitor, as available.

    Measured: From induction of anesthesia to end of surgery (intraoperative period).

Secondary outcomes (7)
  1. Type of Vasopressor Administered

    Type of vasopressor administered intraoperatively, categorized as ephedrine, norepinephrine, adrenaline, dopamine, or dobutamine.

    Measured: From induction of anesthesia to end of surgery.

  2. Estimated Blood Loss

    Total estimated intraoperative blood loss in milliliters.

    Measured: From start to end of surgery.

  3. Number of Blood Transfusions

    Number of units of packed red blood cells transfused intraoperatively.

    Measured: From start to end of surgery.

  4. ICU Admission Rate

    Percentage of patients requiring admission to the intensive care unit after surgery.

    Measured: Within 24 hours after surgery.

  5. Length of Hospital Stay

    Total number of days from the date of surgery to the date of hospital discharge.

    Measured: Up to 60 days after surgery

  6. Postoperative Complications

    Incidence of postoperative complications such as pancreatic fistula, anastomotic leak, surgical site infection, hemorrhage, and acute kidney injury.

    Measured: Up to 30 days after surgery.

  7. 30-Day Mortality

    All-cause mortality within 30 days after surgery.

    Measured: 30 days postoperatively.
