ABSTRACT
Objectives An observational, retrospective, longitudinal, and analytical study aimed to evaluate the effectiveness of the erector spinae plane (ESP) block in managing pain in patients with vertebral fractures secondary to tumoral activity. This study included patients treated at the Pain Clinic who underwent ESP block. The objectives were to describe demographic characteristics, oncological diagnosis, vertebral fracture features, imaging techniques, medications used, and the level of ESP block. Additionally, pain levels were assessed using a numerical analog scale, and the consumption of opioid analgesic medications before and after the ESP block, during follow-up consultations, along with patient satisfaction. Methodology This retrospective, observational, and analytical study was conducted at the Pain Clinic of the National Cancer Institute of Mexico. Patients with vertebral fractures secondary to tumor activity were included, with data collected from March 2020 to September 2023. A consecutive non-probabilistic sampling method was employed, and specific inclusion and exclusion criteria were applied. Data were analyzed using descriptive statistics and the Wilcoxon signed-rank test for quantitative variables, with a significance level of p ≤ 0.05. IBM SPSS Statistics v. 26.0 (IBM Corp., Armonk, NY) software was utilized. Results A sample comprising 16 individuals was obtained, with an equal distribution between males and females. Fracture levels displayed variation, with L3 (12.5%) and T6 (12.5%) being the most prevalent. The ESP approach was primarily conducted using ultrasound (68.8%), while fluoroscopy and computed tomography were utilized in 25.0% and 6.3% of cases, respectively. Predominantly, methylprednisolone and ropivacaine (75.0%) were administered, with phenol used in 18.8% and a combination of methylprednisolone and bupivacaine in 6.3%. Patient satisfaction levels were reported at 81.3% (satisfied or very satisfied). Statistically significant disparities were noted between baseline and incidental pain reduction and oral opioid equivalent dosage in milligrams of morphine per day (MME/day) before and after ESP block (p ≤ 0.05). Conclusions This research provides promising preliminary evidence supporting the effectiveness of ESP block for pain management in vertebral fractures secondary to tumoral activity, enhancing the quality and safety of care for oncology patients. The absence of complications, significant improvement in pain, and reduction in opioid dependence underscore the clinical relevance of this therapeutic approach.
