About this study

Official title: Post-Operative Infusion of Low-Dose Dexmedetomidine for the Control of Post-Operative Pain in Thoracotomy Patients: A Randomized, Double-Blind, Controlled Pilot Study

The purpose of this study is to evaluate the safety, efficacy, hemodynamic and respiratory stability of a low-dose of dexmedetomidine infusion in post-operative surgical in-patients undergoing thoracic surgery after discharge from PACU or ICU.

Read the detailed description

Dexmedetomidine has sedative and analgesic properties that may reduce the opioid requirement in post-operative patients, thereby decreasing the chance of post-operative respiratory depression that occurs with opioid administration. In addition, patients may be more alert with less opioid medication. Currently, dexmedetomidine is not approved for use longer than twenty-four hours and must only be administered in the Intensive Care Unit where patients can be continuously monitored.

This is a prospective, double-blinded, control group pilot study. One group (the control group) will receive a normal saline infusion and the second group (the treatment group) will receive low-dose Dexmedetomidine for up to 24 hours after they are admitted to an open nursing unit (not an Intensive Care Unit).

During the surgery, the anesthesiologist will administer dexmedetomidine during the surgical procedure after an optional loading dose. All patients will receive pain medication using a Patient Controlled Analgesia (PCA) pump as per standard practice. In addition, if the physician deems necessary, an On-Q Pain Pump will deliver local anesthetic surrounding the incision under direction of the surgeon.

Before discharge from the PACU or ICU, each subject will receive either low-dose dexmedetomidine or normal saline using a continuous infusion pump for up to 24 hours after the subject is discharged from either the PACU or the ICU to an open nursing unit. While on the open nursing unit patient vital signs, oxygen saturation, Ramsay score and pain score will recorded every two hours until the treatment drug is stopped.

What is being measured

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

  1. Measure Any Reduction in the Amount of Opioid Administered to Patients in the Dexmedetomidine Study Arm.

    To measure the amount of opioid use requested by patients enrolled in the dexmedetomidine study arm during the observation period of 24 hours, up to 30 hours per patient.

    Measured: An average of 24 hours, up to 30 hours per patient

Secondary outcomes (1)
  1. Measure the Amount of Respiratory Depression in Each Groups

    Respiratory depression and deep levels of sedation can occur when morphine patient-controlled analgesia is prescribed for postoperative patients. In this secondary outcome measure, it was hypothesized that the addition of a dexmedetomidine infusion to the postoperative pain management protocol would reduce the amount of morphine delivered by a PCA pump while providing adequate analgesia. Data are reported for the time period 6 to 16 hours. However, the subjects were on the study for an average of 24 hours, up to 30 hours.

    Measured: Hours 6 to 16

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Dexmedetomidine in people with Post-operative Pain and Respiratory Depression, run by Baylor Research Institute at 1 site in United States.

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 3 inclusion and 17 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: finished, as of the sponsor's last update on 8 Feb 2016. 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 United States. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Aug 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Measure Any Reduction in the Amount of Opioid Administered to Patients in the Dexmedetomidine Study Arm. (time frame: An average of 24 hours, up to 30 hours per patient). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 8 Feb 2016.
