Trial summary

Orthopedic surgery is reportedly among the most painful surgical procedures. Surgical damage following major orthopedic surgery often involves a large, deep incision with considerable tissue dissection and muscle, bone, and vascular exposure. Read more about this study

About this study

Orthopedic surgery is reportedly among the most painful surgical procedures. Surgical damage following major orthopedic surgery often involves a large, deep incision with considerable tissue dissection and muscle, bone, and vascular exposure. Post-operative pain after such surgery is exacerbated on movement or by reflex spasms of the muscles, which may delay mobilization, reduce satisfaction, prolong hospitalization, and possibly increase medical costs.

We design a prospective randomized study for postoperative pain control following total hip arthroplasty.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Bupivacaine in people with Osteoarthritis of Hip, run by Chang Gung Memorial Hospital at 1 site in Taiwan.

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 2 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: status not confirmed, as of the sponsor's last update on 29 Dec 2009. 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 Taiwan. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 Dave W. Chen, M.D. (886-3-3281200 ext. 2420, mr5181@adm.cgmh.org.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pain VAS score (time frame: pre-operaton, immediately post operation, postop 6hrs, postop 12hrs, postop 18hrs, postop 24hrs, post op 48hrs, postop 72hrs). 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 NCT01040273, which also lists 1 linked publication.

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 29 Dec 2009.
