About this study

Official title: Randomized Controlled Trial of the Use of Intramuscular Fentanyl for the Incision and Drainage of Abscess in the Emergency Department

Patients presenting with painful procedures in the Emergency Department (ED) have been shown to frequently have inadequate pain management. The incision and drainage (I\&D) of an abscess is a common procedure that is viewed by many emergency physicians as only requiring a localized anesthetic for pain management. However, it has been documented in previous research that there can be disconnect between what emergency medicine physicians interpret as painful and what patients experience as pain. A trial will be conducted to focus on use of intramuscular (IM) Fentanyl as an intervention to help alleviate pain associated with the incision and drainage of an abscess. This is a procedure that rarely receives systemic opioids.

This double blinded protocol will randomize a total of 50 patients patients with abscesses to receive either a combination of Fentanyl IM followed by subcutaneous (SC) local bupivicaine analgesia or Normal Saline IM followed by SC local bupivicaine analgesia. Only opiate naive patients will be enrolled. The primary outcomes studied are patients overall satisfaction with procedure, and patients level of pain associated with the procedure.

Read the detailed description

Patients presenting with painful procedures in the Emergency Department (ED) have been shown to frequently have inadequate pain management. The incision and drainage of an abscess is a common procedure that is usually treated by emergency physicians with only localized anesthetic for pain management. For those abscesses that require incision and drainage, a physician will usually inject a local anesthetic to help decrease sensation to the affected area prior to incision and drainage. Occasionally, physicians will administer a systemic pain medication, in addition to the localized anesthetic, as a method to better help alleviate pain associated with more complex procedures.

Wilson and Pendleton (1989) wrote a landmark study that highlighted the problem of physicians undertreating patients pain in the ED, a problem known as oligoanalgesia. They found that only 50% of patients with moderate to severe pain were receiving narcotics. Since then the literature has highlighted a number of additional deficits in the use of pain medication in the ED to include the amount of time it takes patients to receive medication, the lack of education medical personnel receive in pain management, the bias that physicians have toward using pain medication, and the lack of pain medication given for painful procedures. Five areas of inadequate management of painful conditions in the ED include 1) failure to acknowledge pain, 2) failure to assess initial pain, 3) failure to have pain management guidelines, 4) failure to document pain and assess treatment adequacy, and 5) failure to meet patients expectations. The use of adequate pain medication for painful procedures covers has been a recent attempt to fill in the gap of one area contributing to oligoanalgesia.

Incision and drainage procedures are a common condition that emergency physicians manage yet there is no evidence to suggest whether they are appropriately managing the pain associated with their treatment. We propose a trial to determine whether intramuscular (IM) Fentanyl, given prior to the incision and drainage of the abscess, decreases the level of pain during/after the procedure and increases the patients overall satisfaction with the procedure.

This double blind protocol will randomize 50 patients with abscesses to receive either a combination of an intramuscular injection of Fentanyl followed by subcutaneous (SC) local bupivacaine analgesia (Fentanyl Group), or a combination of an intramuscular injection of normal saline (Control Group) IM followed by SC local bupivacaine analgesia. Patients will receive a questioner administered by a research assistant after the procedure to assess outcomes of study.

Neither treating physicians, nurses nor patients and research assistants will be aware to which group the patient has been randomized. Fentanyl was chosen due to the rapidity of onset (7-8 minutes) and clearance (1-2 hours). The choice of abscess was made given the ease at which to make a diagnosis, standard treatment with incision and drainage and known association with pain during and after the procedure.

After appropriate identification, screening, and consenting, the patient will then be randomized to receive intramuscular Fentanyl (1 ug/kg) OR Normal Saline (1.5 ml) 7-8 minutes before the procedure is began. Patients in either group will still receive usual care with local subcutaneous bupivacaine anesthetics. Patients are at liberty to request more local subcutaneous bupivacaine and or more pain systemic pain medication and the treating provider may deliver more at their discretion. Contamination may occur if patients receiving IM Normal Saline request systemic narcotics for pain levels not controlled with local bupivacaine alone. These patients may receive systemic narcotics again at the discretion of treating providers. However all patients will remain in the initial group to which they were assigned and data will be evaluated on an intention to treat analysis basis.

What is being measured

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

  1. Highest level of pain during the incision and drainage of the abscess

    After the procedure the following question will be asked via a survey:

    On a scale of 1-10 with 10 being the worst possible pain, what was your highest level of pain during the incision and drainage of the abscess? The answer will be collected via a visual analog scale.

    Measured: Participants will be followed for the duration of hospital stay

  2. Safety of Intramuscular Injection of Fentanyl

    All patients will be monitored to see if any of the following occur after administration of Fentanyl:

    Adverse effects

    • decreased oxygen saturation <95%
    • respiratory depression
    • bradycardia
    • hypotension
    • anaphylaxis or laryngospasm or bronchoconstriction
    • muscle rigidity
    • other:

    Side effects

    • nausea
    • itching
    • drowsiness

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Fentanyl and Normal Saline in people with Abscess, run by University of California, Los Angeles.

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 15 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: withdrawn, as of the sponsor's last update on 20 Jun 2013. Status can change between updates, so confirm with the study contact before making plans.

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 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Highest level of pain during the incision and drainage of the abscess (time frame: Participants will be followed for the duration of hospital stay). The study lists 2 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 NCT01881997, which also lists 10 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 20 Jun 2013.
