About this study

Official title: Analgesic Efficacy of a Naproxen and Lidocaine Gel Combination in Patients With Traumatic Rib Fractures: A Randomized Controlled Trial

This study evaluates whether adding a topical gel containing naproxen and lidocaine to routine intravenous analgesic treatment improves pain relief in adults with isolated traumatic rib fractures presenting to the emergency department. Participants are randomly allocated to receive either standard intravenous dexketoprofen alone or dexketoprofen combined with topical naproxen-lidocaine gel. Pain intensity is measured repeatedly during the first hour after treatment using the Numerical Rating Scale (NRS). The study also examines the need for additional rescue analgesia and monitors treatment-related adverse events to determine the effectiveness and safety of this multimodal analgesic strategy.

Read the detailed description

Pain caused by rib fractures frequently limits deep inspiration and coughing, potentially increasing the risk of respiratory complications. Although systemic analgesics remain the standard approach in the emergency department, combining medications with different mechanisms of action may provide superior pain control while reducing the need for additional analgesics. The present trial investigates whether topical administration of a naproxen-lidocaine gel offers additional analgesic benefit when used alongside routine intravenous NSAID therapy.

This investigation is designed as a prospective, randomized, controlled clinical trial conducted at a tertiary emergency department. Adults diagnosed with isolated rib fractures who meet predefined eligibility criteria are enrolled and randomly assigned to one of two treatment strategies. All participants receive intravenous dexketoprofen as standard care. Patients allocated to the intervention arm additionally receive topical application of a gel formulation containing naproxen and lidocaine over the painful rib fracture region, whereas the comparison group receives standard therapy alone.

Pain severity is evaluated using the Numerical Rating Scale before treatment and at predefined follow-up intervals during the first 60 minutes. The principal outcome is the magnitude of pain reduction achieved with each treatment strategy. Secondary outcome measures include the proportion of patients requiring rescue analgesic medication and the frequency of treatment-related adverse events. Statistical comparisons are planned to determine whether adjunctive topical therapy provides clinically meaningful improvements in early pain management for isolated traumatic rib fractures.

What is being measured

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

  1. Comparison of the decreases in Numerical Rating Scale pain scores between two arms

    Comparison of the absolute and relative (in percentage) changes in Numerical Rating Scale pain scores over time intervals. The Numerical Rating Scale is a score ranging from 0 to 10, where 0 indicates the lowest level of pain and 10 indicates the highest level of pain.

    Measured: 0, 15, 30, 60.minutes and intervals between these time frames

Secondary outcomes (1)
  1. Rate of the rescue analgesia need

    Comparison of the rate of the rescue analgesia need between two arms

    Measured: 60.minute

Questions about this trial

What is this clinical trial studying?

A study testing A gel combination containing 10% naproxen and 5% lidocaine and Dexketoprofen trometamol 50 mg IV in people with Thorax; Fracture and Rib Fracture, run by Ankara City Hospital Bilkent at 1 site in Turkey (Türkiye).

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 8 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 20 Jul 2026. 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 Turkey (Türkiye). 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Comparison of the decreases in Numerical Rating Scale pain scores between two arms (time frame: 0, 15, 30, 60.minutes and intervals between these time frames). 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 20 Jul 2026.
