Objective. The conventional technique used to stimulate the lumbar dermatomes is by stimulation of the dorsal columns of the spinal cord. Until recently, stimulation of nerve roots had not been successfully accomplished. ⋯ Lumbar and sacral NRS trials resulted in adequate paresthesia coverage and effective pain relief in all 5 patients. Further clinical trials to evaluate long-term success rates and safety are indicated. Detailed mapping studies are needed to evaluate the relationship between electrode placement and paresthesia patterns as well as the optimal stimulation parameters.

We analyzed the causes and results of utilization of critical care services in the special care unit in patients after surgical procedures performed by the hepatobiliary surgical service during a 23-month period. ⋯ Respiratory failure was the predominant component of all complications after hepatobiliary surgery. No clinically useful predictors of eventual outcome could be identified.

Objective. Over the past two decades, with the increasing use of spinal instrumentation to treat deformity, surgical restoration has become more frequent. A complication of surgical reconstruction for adult scoliosis, the iatrogenic flat back syndrome, has been described. ⋯ Given the unpredictability of spinal osteotomy to address this pain, a possible alternative treatment strategy is presented. This involves the use of selective pharmaceutical therapy and spinal cord stimulation. Based on the response of this patient to spinal cord stimulation, it is a possible that a component of this persistent pain is neuropathic, despite the fact that preoperative imaging studies failed to disclose a significant compressive lesion.

Spinal subdural haematoma is a rare entity. Only a few cases have been reported, mainly in patients with coagulopathies or bleeding diathesis, and also in patients undergoing anticoagulant therapy following surgery, trauma, or lumbar puncture. Symptoms of spinal cord compression produced by spinal subdural haematoma may progress rapidly causing complete and irreversible deficits. ⋯ She was discharged to an inpatient rehabilitation facility. Follow-up at 1 year showed significant improvement in motor function, but absence of posterior column function. A follow-up magnetic resonance study demonstrated widening of the spinal cord, advanced myelomalacia and a large, central, multi-loculated syrinx.
