Plain English Summary
Background and study aims
Treating of background pain in burned patients is difficult and requires high doses of opioids (pain relief medications) which often results in unfavorable symptoms and sometimes a life threatening complications such as respiratory depression. Intravenous administration (inserting liquids directly into a vein) of lidocaine (a type of opioid) showed a good effect in treating pain in burns. It has a peripheral and central effect on pain receptors with a significant decrease in release of prostaglandin E for burns in vivo, which is considered one of the most important mediators for peripheral pain. The aim of this study is to compare the opioids sparing effect among patients who received lidocaine IV infusion with that of those who received a placebo (normal saline).
Who can participate?
Adults aged 18 to 70 with burns that are more than 10 percent of their total body surface area .
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group receive the interventional drug of lidocaine intravenously through a vein, this is continued for seven days. Those in the second group receive normal saline for seven days.
What are the possible benefits and risks of participating?
The patients who were given lidocaine can benefit from the decreased pain killer doses. Adverse effects were meticulously monitored and dealt with immediately. Participants are followed up to measure their opioid consumption and pain levels at baseline, days 1-3 and days 4-6.
Where is the study run from?
Linkoping Burn Center (Sweden)
When is the study starting and how long is it expected to run for?
Jan 2003 to April 2017
Who is funding the study?

Pain in burned patients
Participants are randomly allocated to one of two groups: the intervention group or the control group.
Interventional drug: intravenous infusion of lidocaine starting with bolus dose 1 mg/kg, followed by lidocaine infusion 6o ml/hour for four hours 4mg/ml, then continuous infusion 45 ml/hour 4mg/ml for seven days.
Control Group: Equivalent volume of 0.9% Sodium Chloride starting with bolus dose, followed by lidocaine infusion 6o ml/hour for four hours, then continuous infusion 45 ml/hour for seven days.
Participants are followed up to measure their opioid consumption and pain levels at baseline, days 1-3 and days 4-6.
Xylocard : lidocaine, AstraZeneca
Primary outcome measure
Opioid consumption (intravenous and oral in milligram/day) is measured using the recordings from both infusion pump and nurses’ written doses administered at baseline day 0, days 1-3 and days 4-6.
Secondary outcome measures
Pain is measured using the visual analogue scale (measured six times per day) at baseline day 0, days 1-3 and days 4-6.
