Multicenter Study Clinical TrialThe PENCAN 25-gauge needle: a new pencil-point needle for spinal anesthesia tested in 1,193 patients.
The PENCAN 25-gauge spinal needle is a new pencil-point needle with an inner diameter of 0.32 mm resulting in a relatively high cerebrospinal fluid (CSF) flow. The PENCAN 25-gauge needle was tested for ease of identification of a successful dural puncture, the failure rate of spinal anesthesia, and the incidence of postdural puncture headache (PDPH). ⋯ A failure rate of 1.9% together with a 1.3% incidence of PDPH were comparable to other 25-gauge pencil-point needles. The rapid appearance of CSF and a perceptible "click" made prompt recognition of successful dural puncture possible.
