Is there a difference in postdural puncture headache after continuous spinal anesthesia with 28G microcatheters...

In this retrospective study, the question was raised and answered whether the rate of postdural puncture headache (PDPH) after continuous spinal anesthesia with a 28G microcatheter varies using a Quincke or a Sprotte needle. The medical records of all patients with allogenic joint replacement of the knee or hip or arthroscopic surgery of the knee joint undergoing continuous spinal anesthesia with a 22G Quincke (n=1,212) or 22G Sprotte needle (n=377) and a 28G microcatheter during the past 6 years were reviewed. We obtained the approval of the ethical committee. The rates of PDPH were statistically not different between both groups: 1.5% of patients developed PDPH after dura puncture with a Quincke needle and 2.1% with a Sprotte needle in women and men.
