: Intravascular Injection Rates During Cervical Medial Branch Block

Vascular Complications Clinical Trial

Official title: Comparison of Intravascular Injection Rates During Cervical and Lumbar Medial Branch Block Using Touhy or Quincke Type Needle

Status Completed

Clinical Trial Summary

The purpose of this study is to compare using Toughy needle has an advantage of reducing intravascular injection rates during cervical medial branch block.

Clinical Trial Description

In previous reports, the use of Toughy needle was thought to reduce the incidence of intravascular injection as low as 2.9% during lumbar transforaminal injection.

Blunt needles with a pencil point tip, such as Whitacre needles, are not as sharp at their tip as are Quincke needles, which have bevels. Toughy or blunt needles may therefore be less likely to penetrate a vessel during a procedure. Hence, we postulated the incidence of intravenous uptake would be significantly lower using a Toughy needle than using a Quincke needle for lumbar medial branch block. To confirm the intravascular injection rates, we used the real time fluoroscopy after injection of contrast medium.

The goal of this study was to compare the incidence of intravascular injection rate betweeen Toughy and Quincke needles using real time fluoroscopy during cervical medial branch block ;
