C-arm fluoroscopic guided subarachnoid block: a single centre experience

Abstract

Subarachnoid block is routinely accessed blindly by the use of anatomical landmarks in the localization of the subarachnoid. Performing the procedure using the landmark technique in patients with spinal deformities or morbidly obese can inflict discomfort to the patient from multiple needle pricks or prolonged positioning during the procedure. This article aims to demonstrate the use of C-arm fluoroscopy for easy and smooth access into the subarachnoid space. This was a retrospective review of all patients who had subarachnoid block with the aid of C-arm fluoroscopy for surgeries involving the pelvis and perineum at Colworths Medical Centre, Port Harcourt from September 2020 to June 2022. Data were collected from the patients records over the period of study, there were seven cases recorded. Of the 7 cases, 5 were males and 2 females. Fluoroscopy allows visualization of the needle path and additionally identifies pathological conditions before needle insertion.
