The Effects of Peri-Operative Pregabalin Administration on Post-Operative Analgesia in Patients Undergoing Coronary Bypass Grafting - Full Text View

Sponsored by:	University of Manitoba
Information provided by:	University of Manitoba
ClinicalTrials.gov Identifier:	NCT00623285

Purpose

We hypothesize that the perioperative administration of pregabalin will significantly decrease pain scores and post-operative opioid requirements for patients undergoing coronary artery bypass grafting, and reduces the incidence of opioid-induced side effects such as respiratory depression. This may reduce ICU admission and possibly abbreviate length of hospital stay.

Further study details as provided by University of Manitoba:

Primary Outcome Measures:

Pain scores and morphine consumption post surgery [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

To determine the occurrence of opioid-related side effects such as nausea, vomiting, and respiratory depression in patients receiving pregabalin compared to those receiving placebo. [ Time Frame: 6 days ] [ Designated as safety issue: Yes ]

Estimated Enrollment:	40
Study Start Date:	April 2008
Estimated Study Completion Date:	March 2009
Estimated Primary Completion Date:	December 2008 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Group 1: Experimental	Drug: Pregabalin Pregabalin 150mg orally 60 minutes pre-operatively. Patients will receive the first dose post-operatively 12 hours after the initial dose was taken (+ 6 hours) given that patient is able to swallow and then they will receive 150mg twice a day through the first 2 post-operative days for a total of six doses.
Group 2: Placebo Comparator	Drug: Placebo/Lactose Matching Placebo orally,60 minutes pre-operatively. Patients will receive the first dose post-operatively 12 hours after the initial dose was taken (+ 6 hours) given that patient is able to swallow and then they will receive placebo twice a day through the first 2 post-operative days for a total of six doses. If the patient is unable to swallow and NG tube is in place, the medication can be dissolved in water and administered through the NG tube.

Assigned Interventions

Group 1: Experimental

Drug: Pregabalin

Pregabalin 150mg orally 60 minutes pre-operatively.

Drug: Placebo/Lactose

Matching Placebo orally,60 minutes pre-operatively.

Eligibility

Ages Eligible for Study:	18 Years to 70 Years
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria

Patients whom are able and willing to provide written informed consent.
Male and female 18-70 years of age.
Patients whom are undergoing isolated coronary artery bypass grafting through a midline sternotomy for the treatment of ischemic heart disease.
Patients whom are able to operate a PCA machine.

Exclusion criteria

Patients undergoing cardiac surgery for valvular or pericardial surgery.
Patients with a documented ejection fraction of less than 50%.
Patients with known chronic renal insufficiency and a calculated creatinine clearance of < 60mL/min.
Patients with known sensitivity to the study drugs.
Patients with documented pre-existing chronic pain.
Patients with seizure disorders.
Patients whom are taking pregabalin or gabapentin
Patients on chronic neuroleptic medications for control of psychiatric disorders as to avoid possible drug interactions and to avoid modulation of any pain states by such medications.
Patients whom are taking tricyclic antidepressants or serotonin and norepinephrine re-uptake inhibitors(SNRI) will be excluded because of the effect of these drugs on neuropathic pain.
Patients greater than 70 years of age will also be excluded because of their increased risk of side-effects and perioperative confusion.
Pregnant or breast feeding females
