Neuroanesthesia & neurocritical care
Comparative effectiveness of anesthetic technique on outcomes after lumbar spine surgery: a retrospective propensity score-matched analysis of the National Surgical Quality Improvement Program, 2009–2019
Authors' conclusion
Compared with GA, RA was associated with fewer complications, less blood transfusion and shorter LOS after spine surgery.
