Abstract
Background/Objectives: Degenerative lumbar spine disease (DLSD) is increasingly managed with minimally invasive surgery (MIS) and evolving anesthesia methods. While general anesthesia (GA) remains standard, spinal anesthesia (SA) may offer faster recovery and fewer side effects. This study compares the clinical and economic outcomes of GA versus SA in transforaminal lumbar interbody fusion (TLIF). Methods: A retrospective review of 18 TLIF patients (2018-2022) was performed, with 9 patients in each cohort. Patients were matched by demographics and procedure type. Data collected included operative time, blood loss, complications, postoperative opioid utilization, and 30-day readmissions. Costs were analyzed in categories: anesthesia, implants, inpatient care, operating room (OR) supplies, OR time, and PACU fees, using Wilcoxon Rank T-tests and Pearson Chi-Squared tests. Results: Clinical outcomes such as blood loss, and operative time were similar between groups. However, SA patients had significantly shorter LOS compared to GA (SA: 12 h vs. GA: 84 h, % difference: -150%, p = 0.04). Additionally, SA patients had lower total direct costs ($27,881.85 vs. $35,669.01; p = 0.027). Significant cost reductions with SA were noted in OR supplies/medications ($7367.93 vs. $10,879.46; p = 0.039) and inpatient costs ($621.65 vs. $3092.66; p = 0.027). Within these categories, reductions were observed for intravenous solutions, sedatives/anesthetics, pressure management, labs, imaging, evaluations, hospital care, and medications. Although costs for implants, anesthesia care, OR time, and PACU fees were lower with SA, these differences did not reach statistical significance. Conclusions: In TLIF for DLSD, SA provides significant economic advantages over GA while yielding comparable clinical outcomes. These results support SA as a cost-effective alternative, warranting further prospective studies to confirm these findings.

Christopher Ignatius Shaffrey
I have more than 25 years of experience treating patients of all ages with spinal disorders. I have had an interest in the management of spinal disorders since starting my medical education. I performed residencies in both orthopaedic surgery and neurosurgery to gain a comprehensive understanding of the entire range of spinal disorders. My goal has been to find innovative ways to manage the range of spinal conditions, straightforward to complex. I have a focus on managing patients with complex spinal disorders. My patient evaluation and management philosophy is to provide engaged, compassionate care that focuses on providing the simplest and least aggressive treatment option for a particular condition. In many cases, non-operative treatment options exist to improve a patient’s symptoms. I have been actively engaged in clinical research to find the best ways to manage spinal disorders in order to achieve better results with fewer complications.

Nicole Renee Guinn
Originally from Anchorage, Alaska, Dr. Guinn attended Mount Sinai School of Medicine in New York, NY, where she graduated with AOA honors. She then completed her anesthesiology residency and fellowship in cardiothoracic anesthesia at Duke University Medical Center, staying on as faculty after completing her training. Dr. Guinn served as the Medical Director of the Center for Blood Conservation at Duke University Medical Center from 2013-2022, working with patients who decline transfusion to receive safe care and improved outcomes, and developing an institutional Preoperative Anemia Clinic to diagnose and treat anemia in operative patients at risk for transfusion. She is known nationally for her expertise in management of patients “When Blood is Not an Option” and for preoperative optimization of anemia in surgical patients and is the current Chair for the ASA Committee on Patient Blood Management. Dr. Guinn is also involved with the American Board of Anesthesiology, serving as an OSCE Committee member and APPLIED examiner for board certification in the anesthesiology. She is the current Interim Division Chief of neuro-anesthesiology, otolaryngology and offsite anesthesia at Duke University.

As a Neurosurgeon with fellowship training in Spine Surgery, I have dedicated my professional life to treating patients with spine disorders. These include spinal stenosis, spondylolisthesis, scoliosis, herniated discs and spine tumors. I incorporate minimally-invasive spine (MIS) techniques whenever appropriate to minimize pain and length of stay, yet not compromise on achieving the goals of surgery, which is ultimately to get you back to the quality of life you once enjoyed. I was drawn to medicine and neurosurgery for the unique ability to incorporate the latest in technology and neuroscience to making patients better. I will treat you and your loved ones with the same kind of care I would want my loved ones to be treated with. In addition to my clinical practice, I will be working with Duke Bioengineers and Neurobiologists on important basic and translational questions surrounding spinal cord injuries (SCI), which we hope to bring to clinical relevance.
