Neurologic Complications of 603 Consecutive Continuous Spinal Anesthetics Using Macrocatheter and Microcatheter Techniques

Continuous spinal anesthesia/analgesia vs. single‐shot spinal anesthesia with patient‐controlled analgesia for elective hip arthroplasty

“…Post dural puncture headache (PDPH) has been described following CSA with various incidences (23–25). In the present study no difference in the incidence of headache between the two groups was observed, but the relatively small number of patients per group does not permit us to draw any solid conclusions.…”

Patient-Controlled Spinal Analgesia for Labour and Caesarean Delivery

“…A retrospective review of use of macrocatheters (20 and 24 gauge) suggests an incidence of PDPH of 3% in the non-obstetric population. Parturients in the same series had an alarming incidence of 33% after microcatheter (28 gauge) insertion 18 . Further studies are indicated in this area.…”

“…Even when catheters of 22 gauge are used, it would seem prudent to use only bupivacaine in the minimum effective dose. Even then, neurological complications can occur 18 .…”

Isobaric bupivacaine via spinal catheter for hip replacement surgery: ED50 and ED95 dose determination

“…Post‐dural puncture headache and neurotoxicity have been described following CSA with various incidences (22, 23). In the present study, only one of the 48 patients experienced post‐dural puncture headache.…”
