Eligibility criteria

Inclusion Criteria:Eligible patients are those who present to an ED for treatment of acute abdominal pain. Acute will be defined as pain for no more than seven days. At the time of enrollment, the ED treatment plan must include use of an intravenous opioid.

Exclusion Criteria: Patients will be excluded from participation if they have cardiac conduction system impairment ( duration > 0.5s, QRS duration > 0.12s, or PR interval duration > 0.2s), known renal (CKD >2) or liver disease (Childs-Pugh B or greater), are hemodynamically unstable, as determined by the attending physician, are pregnant or breastfeeding, or have a known allergy to either medication. Patients will also be excluded if they have used prescription or illicit opioids within the previous week, or if they have a chronic pain disorder, defined as use of any analgesic medication on more days than not during the month preceding the acute episode of pain. Patients weighing \< 60kg or > 120kg will be excluded.

Terms in these criteria, in plain language(1)

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.

QT and QTc

On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.

The study may name a correction formula and a limit in milliseconds, often around 450–480.

What researchers measure

Primary outcomes

  1. Change in 0-10 Pain Scale Between Baseline and 90 Minutes

    Participants were asked to describe their pain on a scale from 0 to 10 with 0= no pain and 10= the worst pain imaginable

    Time frame: up to 90 minutes

Secondary outcomes

  1. Rescue Medication

    no need for off-protocol parenteral pain medication during the ED visit. The following parenteral medications will be considered off protocol pain medication: any opioid, any non-steroidal anti-inflammatory drug

    Time frame: 4 hours

  2. Adverse Events

    Any new symptom development after administration of investigational medication

    Time frame: 4 hours
