O. Richard et al., DECREASE OF SIDE-EFFECTS AFTER LUMBAR MYELOGRAPHY BY THE USE OF VERY THIN NEEDLE, Revue de chirurgie orthopedique et reparatrice de l'appareil moteur, 79(2), 1993, pp. 140-142
The authors report the adverse reactions to myelography in two groups
of patients. The only difference was the spinal needle size: 20 G (0,9
mm) in the first group versus 26 G (0,45 mm) in the second one. In th
e second group the adverse reactions appear 3 to 10 less frequent and
3 to 5 less lasting.
