May favor Whitacre needles to lower headache risk in young patients; leaves open confirmation by randomized trials before practice change.
Does spinal anaesthesia through a 22-gauge Whitacre spinal needle reduce the incidence of post-spinal headache compared to a 25-gauge Quincke spinal needle in young orthopaedic patients?
The 22-gauge Whitacre spinal needle is associated with a lower incidence and shorter duration of post-spinal headache compared to the 25-gauge Quincke needle in young orthopaedic patients.
