INTRODUCTION
The subarachnoid block is routinely performed blindly by
the use of anatomical landmarks in identifying the lumbar
interspace using an imaginary line drawn across the
highest point of both iliac crests known as Tuffier’s line.

Ultrasound imaging is deployed in the localization of the
subarachnoid space for spinal anaesthesia. The use of
ultrasound has been shown to reduce the number of
attempts required in performing a subarachnoid block.

Ultrasound is valuable in accessing the subarachnoid space
in predicted difficult cases, real-time ultrasound guidance
for spinal anaesthesia in challenging patients provided
lower needle insertion attempts and patient satisfaction
when compared with using the landmark technique.

This
notwithstanding, the use of ultrasound in localization of
the subarachnoid space has some setbacks similar to the
conventional palpation method, it was observed that
accuracy was largely dependent on the observer’s
proficiency, even in the hands of the experienced
anaesthetist in the use of ultrasound, misinterpretation of
the intervertebral levels of the spine has been noted, this is
seen in patients with severe spinal deformities and the
supra obese.

Fluoroscopy is a well-established imaging tool in
operating theatres and pain clinics. 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.

The use of fluoroscopy
in accessing the subarachnoid space has the advantage of
showing real-time images and provides accurate
visualization of the intervertebral space and needle paths.

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.
