Study Summary
The aim of the study was to quantify the difference between a 22-gauge needle and 25-gauge needle during lumbosacral epidural steroid injection in regards to intravascular uptake and pain perception. There is the notion that a smaller gauge needle may lead to less intravascular uptake and less pain.
Primary Outcome
The intravascular uptake percentage reported in the study is the percent of 'needles' that showed intravascular uptake. Hence higher 'intravascular uptake percentage' means worse outcome. The mean percentages were averaged across participants were compared between treatment arms. Presence or absence of intravascular uptake during live fluoroscopy and/or blood aspiration per needle. Once needle reached its target (epidural space), contrast was injected to confirm the presence or absence of intra
Interventions
- DEVICE 22-gauge needle
