Opioid Sparing Anesthesia in Lumbar Spine Surgery
Study Details
Study Description
Brief Summary
The aim of this double blind randomized study will be to investigate the effect of an opioid-free anesthesia regimen with a mixture of dexmedetomidine-lidocaine-ketamine in the same syringe versus remifentanil analgesia in lumbar spine surgery

Detailed Description
Lumbar spine surgery is associated with high pain scores and perioperative disability. Ketamine, lidocaine and dexmedetomidine have all proven but varied analgesic effects. High opioid consumption has been associated with multiple side effects.
This double blind clinical trial aims to investigate the possible reduction of opioid use during lumbar spine surgery by administering ketamine, lidocaine and dexmedetomidine. Sixty patients will be randomly allocated into two groups. The control group will receive a continuous infusion of remifentanil, while the Dexmedetomidine-Ketamine-Lidocaine (DKL) group will receive a continuous infusion of ketamine, lidocaine and dexmedetomidine, during the surgery and shortly after
Both infusions will be administered blindly. Fentanyl and morphine will be administered to each patient so as to maintain hemodynamic stability and pain relief. The study will eventually compare the need for bolus doses of fentanyl during the surgery and morphine shortly after in each group.
Multiple hemodynamic parameters, analgesic consumption, possible side effects, patient satisfaction and the Oswestry low back pain disability questionnaire will be recorded.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Active Comparator: dexmedetomidine-ketamine-lidocaine (DKL) group combination of dexmedetomidine, ketamine and lidocaine in one syringe |
Drug: dexmedetomidine-ketamine-lidocaine
In the DKL group, patients will be administered in a total volume of 20 mL,1mL/10 kg of the solution containing ketamine, lidocaine and dexmedetomidine at predefined concentrations. As maintenance, they will be receiving 1mL/10kg/h of the aforementioned solution

Active Comparator: remifentanil group syringe of remifentanil |
Drug: Remifentanil
In the Remifentanil group, patients will be administered in a total volume of 20 mL, 2 mcg/kg of fentanyl. As maintenance, they will be receiving 1 mL/10kg/h of a remifentanil solution

Outcome Measures
Primary Outcome Measures
- pain score on arrival to Post-Anesthesia Care Unit (PACU) [immediately postoperatively]
pain score by the use of Numeric Rating Scale (NRS) on arrival to PACU, ranging from 0 to 10, where 0 means "no pain" and 10 means "worst pain imaginable"
- pain score at discharge from Post-Anesthesia Care Unit (PACU) [at discharge from Post Anesthesia Care Unit (PACU), approximately 1 hour postoperatively]
pain score by the use of Numeric Rating Scale (NRS) at discharge from PACU, ranging from 0 to 10, where 0 means "no pain" and 10 means "worst pain imaginable"
- pain score 3 hours postoperatively [3 hours postoperatively]
pain score by the use of Numeric Rating Scale (NRS) 3 hours postoperatively, ranging from 0 to 10, where 0 means "no pain" and 10 means "worst pain imaginable"
- pain score 6 hours postoperatively [6 hours postoperatively]
pain score by the use of Numeric Rating Scale (NRS) 6 hours postoperatively, ranging from 0 to 10, where 0 means "no pain" and 10 means "worst pain imaginable"
- pain score 24 hours postoperatively [24 hours postoperatively]
pain score by the use of Numeric Rating Scale (NRS) 24 hours postoperatively, ranging from 0 to 10, where 0 means "no pain" and 10 means "worst pain imaginable"
Secondary Outcome Measures
- sedation on arrival to Post-Anesthesia Care Unit [immediately postoperatively]
sedation will be assessed with a 5-point sedation scale, where: 1, patient perfectly conscious; 2, patient feels a little drowsy; 3, patient seems to be sleeping but immediately reacts to verbal stimulation; 4, patient seems to be sleeping but slowly reacts to verbal stimulation and 5, patient seems to be sleeping and does not react to verbal stimulation but does react to a stimulus such as shaking or pain
- sedation at discharge from Post-Anesthesia Care (PACU) Unit [at discharge from Post Anesthesia Care Unit (PACU), approximately 1 hour postoperatively]
sedation will be assessed with a 5-point sedation scale, where: 1, patient perfectly conscious; 2, patient feels a little drowsy; 3, patient seems to be sleeping but immediately reacts to verbal stimulation; 4, patient seems to be sleeping but slowly reacts to verbal stimulation and 5, patient seems to be sleeping and does not react to verbal stimulation but does react to a stimulus such as shaking or pain
- time to first request for analgesia [during stay in Post-Anesthesia Care Unit (PACU), approximately 1 hour postoperatively]
the time for the first patient request for analgesia will be noted
- morphine consumption in Post-Anesthesia Care Unit (PACU) [immediately postoperatively]
mg of morphine requested during patient PACU stay
- tramadol consumption in the first 48 hours [48 hours postoperatively]
patients will be followed for cumulative tramadol consumption for 48 hours postoperatively
- fentanyl requirement during surgery [intraoperatively]
dose of required fentanyl intraoperatively to maintain systolic arterial blood pressure and heart rate within the 20% of baseline value
- satisfaction from postoperative analgesia [24 hours postoperatively]
satisfaction from postoperative analgesia on a six-point Likert scale with 1 marked as minimal satisfaction and 6 as maximal satisfaction
