Lumbar Spinal Instability, Lumbar Spinal Stenosis, Lumbar Spine Degeneration
Conditions
Brief summary
Patients presenting for lumbar spine surgery experience pain related to their spine condition. Following surgery, these patients also experience surgical pain resulting from disruption of skin, muscle tissue, vertebrae, intervertebral discs, and facet joints. This pain is often treated with opioid medications - with roughly 40% of patient experiencing sub-optimal pain management. Adequate pain control has become a top priority among professional societies, healthcare systems, and accrediting agencies. The current proposal will provide this critical evidence of feasibility and acceptability of a multi-modal pain management plan for patients undergoing lumbar spine surgery. Additionally, this study will provide critical preliminary data to compare the effectiveness of protocol-driven multi-modal pain management to control post-operative pain, reduce opioid medication use, and improve physical activity, sleep, and health.
Detailed description
Patients presenting for lumbar spine surgery experience pain related to their spine condition. Following surgery, these patients also experience surgical pain resulting from disruption of skin, muscle tissue, vertebrae, intervertebral discs, and facet joints. Proper pain management is necessary to reduce pain-related and medication side effects and to promote rehabilitation. This pain is often treated with opioid medications - with roughly 40% of patient experiencing sub-optimal pain management. Adequate pain control has become a top priority among professional societies, healthcare systems, and accrediting agencies. Multi-modal pain management strategies have been proposed to (1) control pre-operative pain related to spine pathology; (2) employ non-opioid medication peri-operatively to pre-empt post-operative surgical pain; and (3) monitor and control pain intensity before and after surgery. There is a demonstrated lack of evidence regarding optimal post-operative protocols and pathways. The investigators have planned a randomized clinical trial to compare the effectiveness of two methods of peri-operative pain management to reduce post-operative pain and opioid use among patients undergoing lumbar spine surgery. Prior to submission to National Institutes of Health (NIH), Agency for Healthcare Research and Quality (AHRQ), or Patient Centered Outcomes Research Institute (PCORI), it is necessary to demonstrate the feasibility and acceptability of the trial protocol. The current proposal will provide this critical evidence of feasibility and acceptability of a multi-modal pain management plan for patients undergoing lumbar spine surgery. Additionally, this study will provide critical preliminary data to compare the effectiveness of protocol-driven multi-modal pain management to control post-operative pain, reduce opioid medication use, and improve physical activity, sleep, and health.

A protocol directed and clinically appropriate post-operative analgesia. In this study, standard post-operative analgesia is defined as: oxygen, volatile anesthesia, fentanyl, hydromorphone.
DRUGStandard analgesia use [Hydromorphone]
A protocol directed and clinically appropriate post-operative analgesia. In this study, standard post-operative analgesia is defined as: oxygen, volatile anesthesia, fentanyl, hydromorphone.
DRUGStandard analgesia use [Volatile Anesthesia]
A protocol directed and clinically appropriate post-operative analgesia. In this study, standard post-operative analgesia is defined as: oxygen, volatile anesthesia, fentanyl, hydromorphone.
DRUGStandard analgesia use [Fentanyl]
A protocol directed and clinically appropriate post-operative analgesia. In this study, standard post-operative analgesia is defined as: oxygen, volatile anesthesia, fentanyl, hydromorphone.
DRUGMulti-modal pain management [Acetaminophen + Gabapentin]
Administration of acetaminophen (1 gm po) plus gabapentin (600-1200 mg po) in the preparation area prior to surgery; pre-induction opioid titration with fentanyl until pain is relieved and/or respiratory depression ensues; intravenous ketamine (1 mg/kg load prior to incision then 10 mcg/kg/min) during surgery; acetaminophen, valium plus gabapentin during hospitalization; and prescription for acetaminophen, valium plus gabapentin at discharge.
DRUGMulti-modal pain management [Fentanyl]
Administration of acetaminophen (1 gm po) plus gabapentin (600-1200 mg po) in the preparation area prior to surgery; pre-induction opioid titration with fentanyl until pain is relieved and/or respiratory depression ensues; intravenous ketamine (1 mg/kg load prior to incision then 10 mcg/kg/min) during surgery; acetaminophen, valium plus gabapentin during hospitalization; and prescription for acetaminophen, valium plus gabapentin at discharge.
DRUGMulti-modal pain management [Intravenous Ketamine]
Administration of acetaminophen (1 gm po) plus gabapentin (600-1200 mg po) in the preparation area prior to surgery; pre-induction opioid titration with fentanyl until pain is relieved and/or respiratory depression ensues; intravenous ketamine (1 mg/kg load prior to incision then 10 mcg/kg/min) during surgery; acetaminophen, valium plus gabapentin during hospitalization; and prescription for acetaminophen, valium plus gabapentin at discharge.
DRUGMulti-modal pain management [Valium + Gabapentin]
