Spinal anesthesia and direction of spinal needle bevel

Eldor spinal needle versus Pencan spinal needle.

Comparison of cutting and pencil-point spinal needle in spinal anesthesia regarding postdural puncture headache

BACKGROUND Postdural puncture headache (PDPH), mainly resulting from the loss of cerebral spinal fluid (CSF), is a well-known iatrogenic complication of spinal anesthesia and diagnostic lumbar puncture. Spinal needles have been modified to minimize complications. Modifiable risk factors of PDPH mainly included needle size and needle shape. However, whether the incidence of PDPH is significantly...

Deflection of spinal needles by the bevel.

Bevelled spinal needles sizes 22 and 25 gauge were passed through tough meat to assess the influence of bevel orientation on the path of the needle. The needle bent away from the bevel surface by about 1 mm for each centimetre of needle travel through the tissue. With an introducer, the deviation was reduced by a reduction of the distance of unsupported travel. Pencil-point needles were less de...

The effect of Pencan needle orientation on spinal anesthesia outcomes.

Slow resolution of block and incidence of side effects deter many practitioners from choosing spinal anesthesia for out-patient surgical procedures. Some studies suggest that controlling bevel or side port orientation of a spinal needle during anesthetic injection can affect occurrence of side effects and time to block resolution. The objective of this study was to determine the effects of vary...
