Continuous spinal analgesia after extensive lumbar spine surgery.

A 77-year-old male underwent L-1 to S-1 spine decompression and fusion from L-3 to S-1. A 25 G spinal catheter was placed intraoperatively and bupivacaine 1.25 mg/ml, fentanyl 2 microg/ml and morphine 3 microg/ml infused. The patient was pain-free for the duration of the infusion. Continuous spinal analgesia was effective after extensive spinal surgery. The risks of post-dural puncture headache, infection of wound and/or meninges and the optimum drug doses and combinations are yet to be quantified in this setting.
