About this study

Official title: The Use of a Single, Low-dose Dexamethasone in Total Knee Arthroplasty

This study was conducted to determine the efficacy of an additional preemptive, single, low-dose dexamethasone in terms of incidence and severity of postoperative nausea/vomiting (PONV), pain level, and the safety in terms of wound complications in patients managed with our antiemetic protocol based on Ramosetron following TKA.

Read the detailed description

Postoperative pain and emesis can cause postoperative systemic complications and delay recovery and rehabilitation in patients following total knee arthroplasty (TKA). Furthermore, patients who suffered from severe postoperative pain and emesis tend to be dissatisfied with their surgical treatments. Although contemporary protocols to control perioperative pain and emesis after TKA have been reported to substantially reduce postoperative pain and emesis compared with traditional measures, pain and emesis after TKA remain to be a challenging issue for patients and health care providers. In our previous study, the use of Ramosetron was found to reduce postoperative emetic events, but the antiemetic effects by Ramosetron were incomplete. In search of a further antiemetic measure, we identified the use of dexamethasone as the additional measure fortifying our antiemetic protocol using Ramosetron.

What is being measured

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

  1. Incidence of Nausea and Vomiting

    A clinical investigator who is blinded to randomization assessed the incidence of postoperative nausea which defined as subjective unpleasant sensation associated with awareness of the urge to vomit and as emetic episode and vomiting

    Measured: within 72 hours after surgery

Secondary outcomes (2)
  1. Pain Level

    A blinded investigator asked participants to recall the most severe pain level during 6 to 24 hour after surgery using with a visual analogue scale that ranged from 0 (no pain) to 10 (worst imaginable pain).

    Measured: 6 to 24 hours after surgery

  2. Wound Complication

    Number of participants with a sinus tract communicating with the prosthesis; a pathogen was isolated by culture from tissue or fluid samples taken from the affected joint; tests revealed elevated serum erythrocyte sedimentation rate (ESR) or serum C-reactive protein (CRP) concentration with elevated synovial white blood cell (WBC) count or neutrophil percentage; or pus discharge from the affected joint was present within 30 days after total knee arthroplasty were measured.

    Measured: within 30 days after surgery

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Dexamethasone in people with Osteoarthritis, Knee, run by Tae Kyun Kim at 1 site in South Korea.

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 7 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 27 May 2013. 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 South Korea. 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?

Yes. Results are posted in the registry (first posted 21 May 2013). 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?

Incidence of Nausea and Vomiting (time frame: within 72 hours after surgery). 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 27 May 2013.
