“Anybody who is in health care or has a family member who has had surgery knows that pain control is important, but narcotics can produce many adverse effects,” said G. Ying Li
“Reducing the number of opioids consumed by adding non-narcotic medications, which is termed ‘multimodal pain management,’ makes for a much better experience for adolescents undergoing this procedure for scoliosis.”
The adolescents who had rods and screws inserted to fuse their spines into a straighter position would receive narcotics either intravenously or through a catheter that went into the spinal canal after surgery.
Li worked with Rebecca Hong, M.D., co-author and clinical assistant professor of anesthesiology at U-M Health, to begin administering morphine intrathecally, or through a single injection into the fluid around the spinal cord, without the need for any IV narcotics after surgery.
With improved pain control, they were able to reduce the average hospital stay to only two days, and the practice became standard at the hospital. Still, side effects persisted among patients.
For the study, published in the Journal of Orthopaedic Surgery and Research researchers examined the postoperative course of 50 adolescents with scoliosis who had spinal fusion surgery.
Half were given intrathecal morphine only while the other 25 also received gabapentin before and after the procedure. All patients received Tylenol, ibuprofen and a muscle relaxant.
Researchers found that approximately half of the group who took gabapentin experienced nausea, vomiting and itching after surgery, compared to over 70-80% of the group who received solely intrathecal morphine.
The first group also had significantly lower mean total oxycodone consumption during the hospitalization and had more consistent pain scores with fewer reported spikes.
“Our use of intrathecal morphine and transitioning directly to oral pain medications the day after surgery had already led to our patients getting discharged sooner after this surgery than at most other children’s hospitals because their pain was so well-controlled,” Hong said.
“However, we continually seek to improve our process, and our patients’ and their family’s satisfaction with the care they receive here. The addition of gabapentin has helped in regard to both metrics.”
Future studies are needed for clinicians to find the optimal dosing for the gabapentin-intrathecal morphine combination, researchers concluded.
But the method of reducing opioid intake by adding gabapentin has potential to be considered for other procedures beyond spinal fusion for scoliosis, which is a procedure that approximately 38,000 children in the United States undergo every year, Li said.
“What a lot of providers want is to be able to provide multimodal pain management, not just for kids and orthopaedic surgery,” she said.
“During this opioid epidemic, we want to provide options that include non-narcotics to decrease the amount of narcotics we are prescribing and, ultimately, decrease the amount of leftover narcotics at home that can get into the wrong hands.”
