Eight different epidural needles (Tuohy Everett, Pitkin, Braun Perifix and Portex in 16‐gauge, and Becton Dickinson Crawford, Becton Dickinson B‐D, Monoject and Portex in 18‐gauge) were evaluated using a scanning electron microscope and spectral x‐ray analysis. Differences were noted in the metal composition, between disposable and reusable needles with respect to molybdenum content. The inner surface of the 18‐gauge Crawford needle was found to be the smoothest and it also had the best clearance between the needle and stilette. The Portex 16‐gauge had the best needle/stilette fit at its bevel. The hardness of the metal was found to be satisfactory in all the needles.
