简要总结
Total knee arthroplasty (TKA) is one of the most painful orthopedic procedures. After TKA surgery, postoperative pain relief may be achieved using a variety of techniques. Integral to recovery and improved outcomes is early ambulation and mobilization. Achieving adequate postoperative pain control while ensuring the ability to ambulate early can be quite challenging.
Currently, in our country there has been a call to address prescription opioid use and abuse due to a nationwide opioid epidemic. In light of this, improving our multimodal analgesic protocol will serve to decrease reliance of opioid medications for pain control. Multimodal analgesia is effective in decreasing total opioid consumption postoperatively. Dextromethorphan is a low-affinity noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist. It has a long history of clinical use with an established safety record. Studies have shown that it has a positive effect as an analgesic.
In order to see if dextromethorphan will decrease opioid use, this study will look at two patient groups undergoing total knee arthroplasty with the same preoperative, intraoperative, and postoperative anesthetic plan with the exception of the addition of dextromethorphan to one groups multimodal analgesic regimen. This study is designed as a double-blinded, randomized, prospective cohort trial.
详细描述
Each subject will receive as part of their standard of care a spinal with sedation for intraoperative anesthesia.
Subjects will be randomly assigned using computer generated allotment. The group designation will be placed in sealed envelopes. The group listed will determine whether or not they will receive dextromethorphan as part of their preoperative preincisional analgesic regimen. Only the pharmacist dispensing the medication will be unblinded. The drug and placebo will then be concealed by the pharmacist and delivered to the patient to ingest in the preoperative area.
Group A: standard preop meds
Group B: standard preop meds + dextromethorphan
The standard preoperative analgesic regimen will include placement of an adductor canal catheter nerve block, acetaminophen 1000mg PO, oxycodone extended release 10mg PO, celecoxib 400mg PO (held if elevated creatinine), and pantoprazole 40mg PO
