Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Qualitative and quantitatively evaluate the pain control and incidence of adverse effects in patients undergoing corticosteroid infiltration and local anesthetic through sacral epidural puncture with ultrasound assistance or isolated use of fluoroscopy to aid puncture and location of the sacral epidural space. A group will be submitted to epidural corticosteroid infiltration associated with local anesthetic with the use of fluoroscopy for locating the sacral epidural space, which is currently the gold standard for this technique, while in another location group will be held with the use of ultrasound.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Introduction: Procedures guided by ultrasound (USG) have advantages over traditional techniques (fluoroscopy) with respect to regional anesthesia. Some studies have shown its usefulness as a quick, safe and simple tool for the location of the sacral hiatus and to guide the puncture of the sacral epidural space in patients with chronic low back pain, despite the lack of data with respect to clinical outcomes.

OBJECTIVES: Evaluate qualitatively and quantitatively the pain control and incidence of adverse effects in patients undergoing corticosteroid infiltration and local anesthetic through sacral epidural puncture with ultrasound assistance or isolated use of fluoroscopy to aid puncture and location of the sacral epidural space. It will also be evaluated success rate in the first puncture, and the time duration of the procedure in groups.

METHODS: It is clinical, analytical, prospective trial, randomized, covered for evaluators. It will include 30 patients with chronic low back pain or pain in the lower limbs resulting in lumbar canal stenosis, refractory to medical treatment. A group will be submitted to epidural corticosteroid infiltration associated with local anesthetic with the use of fluoroscopy for locating the sacral epidural space, which is currently the gold standard for this technique, while in another location group will be held with the use of ultrasound.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Ultrasound

The group I will be subjected to epidural infiltration using methylprednisolone acetate diluted in ropivacaine 0.1%. Initially the sacral hiatus is identified by palpation. After, the ultrasound device is used (USG) for the puncture, with a linear transducer of high frequency. At the end of corticosteroid administration, the placement of the needle tip will be checked with fluoroscopy and noted.
