They feature a bevelled tip, designed to puncture through tissue, with an opening at the tip to facilitate collection of CSF or injection of therapeutics.
Do ‘atraumatic’ needles reduce headache postlumbar puncture incidence?
Needle tip design has been proposed to affect the incidence of headache postlumbar puncture, with pencil-point ‘atraumatic’ needles thought to reduce its incidence in comparison to bevelled ‘traumatic’ needles. Despite this, the use of atraumatic needles and knowledge of their existence remains significantly limited among clinicians.
What are the advantages of eyeless atraumatic sutures?
The suture manufacturer swages the suture thread to the eyeless atraumatic needle at the factory. The chief advantage of this is that the doctor or the nurse does not have to spend time threading the suture on the needle, which may be difficult for very fine needles and sutures.
