About this study

Official title: Analgesic and Hemodynamic Effects of Continuous Epidural Analgesia Compared to Paravertebral Block in Liver Resection Patients

The best mode of analgesia delivery after hepatectomy is currently unknown. Many institutions routinely use continuous epidural analgesia (CEA) for pain control in this patient population. A functioning CEA provides adequate analgesia, but is associated with high failure rates (20-30%) and sometimes significant hemodynamic disturbances (hypotension) requiring an increased amount of intravenous fluid and blood products to maintain homeostasis. Furthermore, its safety has been the subject of debate in liver resection patients due to the elevated risk of epidural hematoma and its serious neurological consequences. These limitations highlight the need to explore other options for analgesic control after hepatectomy, such as paravertebral block (PVB). PVB has been shown to provide similar analgesia with a lower incidence of pulmonary complications, side effects (pruritis, urinary retention, nausea and vomiting, hypotension), and failure rates (6.1%) when compared to CEA in thoracic surgery, and therefore has been suggested as a safer alternative in hepatectomy patients. Despite this, there are no studies comparing the efficacy of CEA and PVB as analgesic techniques after hepatectomy. The investigators propose a randomized controlled trial to compare the analgesic efficacy, side effects, and complications associated with CEA and PVB in patients undergoing elective hepatectomy through a right subcostal incision.

Read the detailed description

The best mode of analgesia delivery after hepatectomy is currently unknown. Many institutions routinely use continuous epidural analgesia (CEA) for pain control in hepatectomy patients. However, its safety has been the subject of debate. Paravertebral block (PVB) has been suggested as a safer alternative in this patient population. Despite this, there are no studies comparing the efficacy of CEA and PVB as analgesic techniques after hepatectomy. Although CEA provides high quality analgesia, and reduces cardiovascular and respiratory complications and the incidence of postoperative thromboembolic events, it is associated with hypotension and complications such as epidural hematoma, epidural abscess, and spinal cord injury, which are serious concerns in hepatectomy patients. Furthermore, patients given CEA are more likely to need blood transfusions, and transfused patients have significantly higher mortality rates, complications related to infection, and hospital length of stay. PVB is a less popular technique that involves injecting local anesthetic (LA) into the paravertebral space. This technique has been successfully used for pain relief after several surgical procedures, including ablation of hepatic tumours and hepatectomy. Although CEA and PVB have never been compared in hepatectomy patients, they have been compared in thoracotomy patients; in this patient population, PVB and CEA provide similar levels of pain control, but CEA is associated with more complications and side effects such as hypotension, nausea, vomiting, and urinary retention, and PVB is associated with better pulmonary function. Both CEA and PVB are reasonably effective for post-hepatectomy analgesia compared to placebo, and have their own strengths and weaknesses. The gold standard CEA provides excellent analgesia at the expense of more intense hypotension, significant failure rates (20-30%), and a higher risk of epidural hematoma and its serious neurological consequences. These limitations highlight the need to explore other options for analgesic control after hepatectomy such as PVB. Therefore, the investigators propose a randomized controlled trial to compare the analgesic efficacy, hemodynamic changes, and side effects in CEA and PVB in patients undergoing elective hepatectomy through a right subcostal incision. Since CEA is currently the gold standard for analgesia after hepatectomy, the investigators propose a non-inferiority trial to determine whether PVB produces a similar analgesic profile to CEA in hepatectomy patients, while being associated with fewer adverse side effects.

This is a randomized, controlled, pilot study. It will consist of two groups of participants undergoing hepatectomy: those receiving CEA, and those receiving PVB for analgesic control. CEA and PVB protocols will follow the usual standard of care at Kingston General Hospital (KGH). Participants in the CEA group will receive bupivacaine with hydromorphone infusion after induction of general anesthesia for surgery. Participants in the PVB group will receive a bolus dose of ropivacaine, and then ropivacaine infusion after induction of general anesthesia. Upon emergence from anesthesia, all participants will be transferred to the post-anesthetic care unit (PACU). Here, CEA participants will be started on patient-controlled epidural analgesia (PCEA) of bupivacaine and hydromorphone plus a self-administered bolus dose with a lockout period of 30 min if participants require additional pain relief, and PVB participants will be started on a patient-controlled paravertebral analgesia (PCPA) of ropivacaine plus a self-administered bolus dose with a lockout period of 30 min if participants require additional pain relief. All participants will receive oral hydromorphone every 4 hours as required for breakthrough pain relief starting on the morning of the second postoperative day. A member of the research team will assess the presence and severity of pain and nausea during the postoperative period. The assessments will be performed at 30 minutes after arrival to the PACU, and thereafter at 4, 8, 24, 48, and 72 hours after surgery. Investigators will ask all participants to score their pain at rest and with coughing on a numeric rating scale (NRS, where 0=no pain and 10=worst pain imaginable), and nausea scores (0=none, 1=mild, 2=moderate, 3=vomiting) at each of the above listed time points. At 72 hours after surgery, participant satisfaction with regard to analgesia will be assessed (1=very poor, 2=poor, 3=satisfactory, 4=good, 5=excellent). The requirement for breakthrough pain relief, the time of first breakthrough pain relief request, and cumulative opioid consumption will be recorded during the postoperative 72 hours.

A Phase 4 study testing Bupivacaine and Hydromorphone and Ropivacaine and Hydromorphone in people with Pain Control After Elective Hepatectomy, run by Dr. Anthony Ho at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 5 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Anthony MH Ho, MD, FRCPC (613-548-7827, anthony.ho@kingstonhsc.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Opioid consumption (time frame: 0-72 hours after surgery). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02909322, which also lists 50 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Dec 2022.
