Endovenous Lidocaine and Serum Cytokines Concentration
February 9, 2015 updated by: Juliano Ferreira, Universidade Federal de Santa Maria
Effect of Endovenous Lidocaine on Analgesia and Serum Cytokines Concentration: Randomized and Double-blind Trial
Ineffective treatment of postoperative pain may cause organic damage and chronic pain.
Nevertheless, opioids, the leading drugs used for this purpose, present side effects that sometimes restrict their usability.
In a multimodal context, new postoperative analgesia techniques have been developed focusing in the reduction of opioid use and their adverse effects, as well as postoperative chronic pain prevention.
In this background, continuous intravenous infusion of lidocaine during perioperative period has shown to be promising.
This trial aimed to compare postoperative analgesia, opioid consumption, duration of ileus and length of hospital stay and IL-1, IL-6, IL-10, α TNF and γ IFN levels in patients undergoing to laparoscopic cholecystectomies who received intravenous lidocaine in comparison to a control group.
Intravenous lidocaine in the perioperative period of laparoscopic cholecystectomies was not able to reduce postoperative pain, opioid consumption, and duration of ileus or length of hospital stay.
However, its anti-inflammatory effect was evidenced by the significant changes in the studied cytokines.

Detailed Description
Forty-four patients undergoing laparoscopic cholecystectomy, under general anesthesia, were randomly allocated in two groups.
The first group received intravenous lidocaine infusion during the procedure until one hour postoperatively; meanwhile the second group received intravenous saline for the same period of time.
The intervention was double-blind.
In the postoperative period, both groups received dipyrone and morphine PCA.
Pain was assessed by Visual Numeric Scale (VNS) at rest and when coughing at 1st, 2nd, 4th, 12th e 24th hour after the end of the surgery.
Blood samples for cytokines measurement were taken at the end of procedure and 24 hours later.
The total morphine PCA demand, the time for the first flatus and the length of hospital stay were also recorded and compared.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
ACTIVE_COMPARATOR: Lidocaine
Group treated with lidocaine solution
|
Lidocaine was administered in bolus of 1.5 mg.kg-1 at the start of the procedure and maintained at a dose of 3 mg.kg-1.h-1
until one hour after the end of the procedure.
Solution of 0,3% lidocaine was used, so that the infusion rate was equal to the weight of the patient.

PLACEBO_COMPARATOR: Placebo
Group treated with saline solution
|
Saline solution was administered in bolus of 1.5 mg.kg-1 at the start of the procedure and maintained at a dose of 3 mg.kg-1.h-1
until one hour after the end of the procedure.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The primary outcome was pain intensity as assessed by visual analogical scale (VAS) scores
Time Frame: 24 hours
|
The primary endpoint was the effect of lidocaine on postoperative pain within the first 24 hours.
Three interns who participante of the study applied VNS to measure the intensity of pain at rest and when coughing 1, 2, 4, 12 and 24 hours after surgery.
|
24 hours
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The secondary outcome was measure of citokynes IL-1 levels
Time Frame: 24 hours.
|
A blood sample was collected by the author or by the anesthetist of the procedure to measure IL-1, IL-6, IL-10, TNF α and IFN γ levels immediately at the end of the surgery and 24 hours after.
The difference of these markers between the two groups also featured secondary outcome.
The samples were centrifuged and the serum was separated in Eppendorfs and then frozen at - 70 Celsius degrees, for posterior simultaneous analysis.
The biochemical responsible for this analysis also did not have contact with the group to which participants belonged.

The secondary outcome was measure of citokynes IL-6 levels
Time Frame: 24 hours
|
The primary endpoint was the effect of lidocaine on postoperative pain within the first 24 hours.
