Study summary

Rate of Intravenous Magnesium Sulfate Vs Lidocaine to treat Renal Colic in the Emergency Department.

Read the detailed description

Magnesium Sulfate (MgSO4) is a N-Methyl-D-aspartate (NMDA) receptor antagonist and is thought to be involved in the modulation of pain. There has been little direct evidence that MgSO4 relieve neuropathic pain and prevents opioid-induced hyperalgesia in humans.

Intramuscular Diclofenac seems to offer the most effective sustained analgesia for renal colic in the ED and has few side effects.

Lidocain became the agent of choice in visceral and central pain. Intravenous Lidocain is effective in the management of neuropathic pain such as diabetic neuropathy, post-surgical pain, post-herpetic pain, headaches and neurological malignancies. At low doses, Lidocain is known as a relatively safe medication. Lidocain seems an effective treatment who can be administrated in the renal colic.

Objective of study:

Evaluate the analgesic effect of a standard dose of intravenous magnesium added to intramuscular diclofenac compared to intravenous Lidocain combined to intramuscular diclofenac or intramuscular diclofenac alone in patients presenting to the ED with renal colic and whether it can reduce opioid consumption.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What researchers measure

Primary outcomes

  1. Treatment success evaluated By VAS Score ( 10 cm Visual analogue Score ) 30 minutes after drug administration.

    Significant pain reduction as at least a 50% drop of VAS Score of the initial pain score at 30 min after analgesia administration ( Drop VAS Score is in favour of analgesic treatment efficiency )

    Time frame: 30 minutes

Secondary outcomes

  1. The proportion of participants with persistent pain (VAS > 2) at the end of the study (90 min)

    The proportion of participants with persistent pain (VAS \> 2) at the end of the study (90 min)

    Time frame: 90 min

  2. Adverse effect

    nausea, vomiting, vertigo, and lethargy based on self-reports and other clinical manifestations occuring at any moment of the protocol

    Time frame: 90 minutes

  3. The need for additional analgesics at 30 minutes after protocol start to relieve the pain

    The need for rescue analgesia

    Time frame: 30 minutes

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 21, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
