Brief Summary

Epidural analgesia is an efficient way to relieve pain after major abdominal surgery. Two different protocols are used to provide analgesia: continuous epidural infusion (CEI) and programmed intermittent boluses (PIEB). CEI consists in the delivery of a continuous administration of the intended hourly dose. PIEB consists in the administration of sequential high pressure boluses of the intended dose. Although some studies in the postoperative setting have observed that PIEB reduces the total dose needed to ensure adequate pain control, the clinical value of this finding is still uncertain. Moreover, nursing and medical interventions to the epidural infusion rates are frequently needed in the first 48 postoperative hours to optimize the provision of analgesia. These interventions add to the already important nursing workload associated with major abdominal surgery, and are correlated with suboptimal analgesia for the patient. This randomized controlled trial aims to compare the effect of epidural PIEB on the workload as a reflection of adequate analgesia compared to the standard CEI protocol in use. The investigators hypothesize that the use of PIEB decreases the number of interventions needed to obtain adequate analgesia.

Outcome Measures

Primary Outcomes (1)

  • Number of epidural infusion adjustments

    Number of epidural infusion adjustments by the nursing team (based on the usual protocol of our institution) will be recorded.

    48 hours after reaching the discharge criteria from the post-anesthesia care unit (or until the beginning of the epidural weaning period, if started in less than 48 hours)

Secondary Outcomes (13)

  • Quality of analgesia

    48 hours after reaching the discharge criteria from the post-anesthesia care unit (or until the beginning of the epidural weaning period, if started in less than 48 hours)

  • Additional analgesia

    48 hours after reaching the discharge criteria from the post-anesthesia care unit (or until the beginning of the epidural weaning period, if started in less than 48 hours)

  • Incidence of hypotension

    48 hours after reaching the discharge criteria from the post-anesthesia care unit (or until the beginning of the epidural weaning period, if started in less than 48 hours)

  • Vasopressor use

    48 hours after reaching the discharge criteria from the post-anesthesia care unit (or until the beginning of the epidural weaning period, if started in less than 48 hours)

  • Total epidural dose of local anesthetic administered

    48 hours after reaching the discharge criteria from the post-anesthesia care unit (or until the beginning of the epidural weaning period, if started in less than 48 hours)

  • +8 more secondary outcomes

Study Arms (2)

Programmed intermittent epidural bolus (PIEB)

EXPERIMENTAL

Programmed intermittent epidural boluses of bupivacaine 0,1% are administered every hour.

Device: Programmed intermittent epidural bolus (PIEB) of bupicavaineDevice: Continuous epidural infusion (CEI) of morphine

Continuous epidural infusion (CEI)

EXPERIMENTAL

A continuous epidural infusion of bupivacaine 0,1% is administered at a prescribed rate in milliliters per hour.

Device: Continuous epidural infusion (CEI) of bupivacaineDevice: Continuous epidural infusion (CEI) of morphine

Interventions

Programmed intermittent epidural boluses of bupivacaine 0,1% are administered every hour. Protocolized adjustments of the dose are performed in order to obtain adequate analgesia. Standardized patient-controlled epidural boluses are available as top-ups.

Continuous epidural infusion (CEI)

A morphine infusion (0,1mg/ml) is administered in both groups at a prescribed rate. Protocolized adjustments of the dose are performed in order to obtain adequate analgesia.
