Lidocaine and Ketamine Versus Standard Care on Acute and Chronic Pain
The Effect of Thoracolumbar Paravertebral Block or Intravenous Lidocaine and Ketamine Versus Standard Care on Acute and Chronic Pain After Inguinal Herniorrhaphy

The investigators are conducting this study to find out if intravenous (injected through the vein) infusion of lidocaine and ketamine administered with general anesthesia is as effective as a paravertebral block in lessening pain after surgery and that both of these techniques are superior to general anesthesia alone in reducing pain immediately after surgery and in the long-term.

Participants will be randomized into one of three study groups; Group 1 - Paravertebral Group - ropivacaine is injected near the spine before surgery. Midazolam and fentanyl are administered intravenously for sedation. Group 2 - Lidocaine/Ketamine - General anesthesia with lidocaine and ketamine administered intravenously throughout your surgery and for 60 minutes after surgery. Group 3 - General Anesthesia Alone. General anesthesia with placebo administered intravenously throughout surgery and for 60 minutes after surgery. All participants will rate their pain on a scale from 0 to 10 after surgery and on days 1 and 2 after surgery. Participants are called 3 and 6 months after surgery for pain and quality of life assessments

 
Interventional
Treatment, Randomized, Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Active Control, Parallel Assignment, Efficacy Study
  • Pain
  • Nausea
  • Drug: ropivacaine
  • Drug: Lidocaine/Ketamine
  • Other: placebo
  • Active Comparator: Paravertebral Group - A local anesthetic (ropivacaine) will be injected near the spine before surgery. Participants will also receive midazolam and fentanyl intravenously (through your vein) for sedation
  • Active Comparator: Participant will receive general anesthesia through the vein before surgery. Lidocaine and ketamine will be administered intravenously throughout surgery and for 60 minutes after surgery.
  • Placebo Comparator: General anesthesia plus placebo. Placebo will be administered intravenously until 60 minutes after surgery
