Pregabalin Versus Dexmedetomidine for Delirium Prevention After Cardiac Surgery: A Randomized Double-Blind Trial

Detailed Description
Pregabalin is a beta-isobutyl of GABA with chemical similarity to gabapentin . Pregabalin binds to the alpha-2-delta subgroup of calcium channels, thereby reducing excitatory neurotransmitter release and preventing hyperalgesia and central sensitization . Pregabalin is used as anticonvulsant but has also been used as analgesic for neuropathic pain and, lately, for postoperative pain, in an attempt to reduce opioid consumption and prevent progression to chronic pain.
Dexmedetomidine with its broad range of effects including easily controllable sedation, analgesia, and anxiolysis still enables the caring medical team to interact with the patient. It reduces the activity while still maintaining the reactivity of neurons in the locus coeruleus. Therefore, it is an appealing alternative to traditional sedatives such as propofol and benzodiazepines.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: pregabalin group
patients will receive pregabalin capsules (75 mg) will be given 2 h prior to induction of anesthesia and every 12 h for 24h postoperatively by nasogastric tube or orally.
Patients will receive IV saline as placebo with the same rate of dexmedetomidine.

patients will receive pregabalin capsules (75 mg) will be given 2 h prior to induction of anesthesia and every 12 hours
|
Active Comparator: dexmedetomidine group
patients in the dexmedetomidine group will receive after induction of GA a bolus dose of 0.4 μg/kg dexmedetomidine (over a period of 10 to 20 min) followed by an infusion of 0.2 to 0.7 μg/kg/h.
Patients will receive placebo 2 h prior to induction of anesthesia and every 12 h for 24h postoperatively by nasogastric tube or orally.
If patients are hemodynamically unstable, the bolus dose will be omitted.
The infusion of dexmedetomidine will be continued for a maximum period of 24 h.
Dexmedetomidine infusion will be not discontinued before extubation.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Incidence of Delirium
Time Frame: 24hour postoperatively
|
Assessment of delirium will be performed preoperatively and postoperatively at 12-h intervals or as needed according to the patient's condition using the confusion assessment method (CAM)
|
24hour postoperatively
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pain score
Time Frame: 24 hours postoperatively
|
Postoperative pain (using VAS) at rest and movement will be measured at PACU, 1h, 2hr. 4hr, 6hr, 8hr, 12hr, 18hr, and 24hrs postoperative. The Visual Analogue Scale (VAS) measures pain intensity. The VAS consists of a 10cm line, with two end points representing 0 ('no pain') and 10 ('pain as bad as it could possibly be'). |
24 hours postoperatively
|
Postoperative opioid consumption
Time Frame: 24 hours postoperatively
|
Patients will receive single 3 mg dose of intravenous morphine and patient control analgesia (PCA) will be started with a programmable PCA pump using the following settings: basal morphine infusion 1 mg/h, bolus dose 1 mg, and lockout time 20 minutes.
|
24 hours postoperatively
|
Sedation
Time Frame: 24 hours postoperatively
|
Sedation level will be recorded using Sedation Agitation Scale
|
24 hours postoperatively
|
Length of hospital stay
Time Frame: One month postoperatively
|
Patients will stay in hospital for one month
|
One month postoperatively
