Association of opioid exposure before surgery with opioid consumption after surgery.
To determine the effect of prescription opioid use in the year before surgery on opioid consumption after surgery. ⋯ Preoperative opioid use is associated with small increases in patient-reported opioid consumption after surgery for most patients, though greater differences exist for patients with chronic use. For most patients with preoperative opioid exposure, existing guidelines may meet their postoperative needs. However, guidelines may need tailoring for patients with chronic use, and providers should anticipate a higher likelihood of postoperative refills for all opioid-exposed patients.

Transforaminal lumbar puncture for spinal anesthesia or novel drug administration: a technique combining C-arm fluoroscopy and ultrasound.
Lumbar puncture (LP) may be challenging for patients with scoliosis and other conditions following previous posterior fusion and instrumentation from thoracic to sacral levels. Interventional radiologists have described CT approaches to transforaminal LP. We hypothesized that combined C-arm fluoroscopy and ultrasound could be a feasible approach to transforaminal LP for interventional pain physicians and regional anesthesiologists. ⋯ Transforaminal LP appears technically feasible for patients with full-spine fusions using a straight-needle approach with combined fluoroscopy and ultrasound guidance. Larger case series and prospective studies may better define the success rates, risks, and benefits of this approach relative to alternative approaches to intrathecal access for patients with previous long-segment posterior spine fusions.

Long-term complications of unintentional dural puncture during labor epidural analgesia: a case-control study.
Epidural analgesia is the preferred method to manage pain during labor and delivery. The insertion of the epidural catheter can be complicated by unintentional dural puncture that may result in postdural puncture headache. There is limited evidence on the long-term implications of this complication. We sought to investigate if women who sustained a dural puncture have a higher risk of developing chronic headache, low back pain and visual or auditory impairment. ⋯ An unintentional dural puncture during epidural catheter insertion in parturients is associated with increased risk of chronic headache, back pain and auditory impairment.
