Impact of Sedation on Patient Satisfaction, Radiation Exposure, and Complications in Lumbar Transforaminal Epidural Steroid Injections: A Retrospective Cohort Study

The study will be conducted by retrospectively scanning the files of patients with paracentral/subarticular protruded disc herniation and who underwent transforaminal epidural steroid injection (TFESE) to the lumbosacral region, at the Algology Department of Kanuni Sultan Süleyman Training and Research Hospital, between January 2021 and January 2024. In order to prevent heterogeneity, magnetic resonance imaging (MRI) of the patients will be evaluated in consultation with a radiologist. will be used. . 201 patients aged 18-65 years, classified as American Society of Anesthesiologists (ASA) 1-3, who underwent unilateral L-TFESI, were included in the study. The patient selection process is shown in Figure 1. The patients' magnetic resonance (MR) images were evaluated by a radiologist with 10 years of experience in the musculoskeletal system. The classification system used in the studies by Pfirmann et al. and Ghahreman et al. was used to grade nerve root compression based on MR imaging. According to this classification system, DH compression was graded as low-grade (1-2) or high-grade (3-4) nerve root compression The Numeric Rating Scale-11 (NRS-11) and Likert scale were recorded on the 4th day and 4th week before and after the procedure. It is stated that the outcome of epidural steroid injections can be predicted from the 4th day onwards
