About this study

Official title: Title: The Effect of Combined Ephedrine and Lidocaine Pretreatment on Pain Due to Propofol Injection in Patients Undergoing Elective Surgery Under General Anaesthesia

Objectives: Injection pain and hypotension are two main adverse effects of propofol which distresses patient. The aim of this prospective double blind study was to compare the effect of ephedrine -lidocaine combination with lidocaine and ephedrine on injection pain and hemodynamic changes due to propofol induction.

Methods: 165 adult patients, aged 20 to 60 yr, Patients were randomly allocated to one of 5 groups (33 patients per group): lidocaine 0.5 mg/kg(L) ,ephedrine 30microgram/kg (E30), ephedrine 70 microgram/kg(E70), lidocaine 0.5mg/kg -ephedrine 30 microgram/kg(LE) or 2ml saline (S) intravenously. After one minute propofol 2 mg/kg into a dorsal hand vein was injected. Face pain scale and verbal rating scale, arterial blood pressure and heart rate were recorded before induction, just before intubation, and one minute after intubation

Being tested
Ephedrine 30microgram/kg, lidocaine0.5mg/kg -ephedrine30 micrograms/kg, ephedrine 70 microgram/kg, lidocaine 0.5mg/kg, normal saline 2ml

What is being measured

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

  1. pain during propofol injection is assessed by face pain scale(FPS) and verbal rating scale(VRS)

    Measured: during the injection period of propofol(One minute after the administration of the test solution) before loss of consciousness

Secondary outcomes (2)
  1. mean arterial blood pressure

    mean arterial blood pressure is assessed by nonivasive automatic blood pressure measurement

    Measured: before the administration of the test solution , just before intubation(three minutes after atracurium injection), and one minute after intubation

  2. heart rate

    is assessed by echocardiogram monitoring

    Measured: before the administration of the test solution, just before intubation(three minutes after atracurium injection) , and one minute after intubation

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Ephedrine 30microgram/kg, lidocaine0.5mg/kg -ephedrine30 micrograms/kg and ephedrine 70 microgram/kg in people with Pain Due to Propofol Injection and Hemodynamic Changes Due to Propofol Injection, run by Qazvin University Of Medical Sciences at 1 site in Iran.

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 1 inclusion and 3 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 11 Oct 2012. 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 Iran. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

pain during propofol injection is assessed by face pain scale(FPS) and verbal rating scale(VRS) (time frame: during the injection period of propofol(One minute after the administration of the test solution) before loss of consciousness). 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 11 Oct 2012.
