The objective of this study was to follow up patients considered for spinal cord stimulation and assess outcomes and patient selection factors associated with outcome. A retrospective study of patients considered for spinal cord stimulation was performed. This included three groups: A) those who did not have a temporary trial of stimulation, B) those who did not go on to have long-term stimulation after a trial, and C) those who did go on to have long-term stimulation after a trial. ⋯ We conclude that spinal cord stimulation is an efficacious therapy which is not associated with serious side effects. There is some reduction in therapeutic efficacy over time. Patients deteriorate without treatment.

The purpose of the study was to determine if functional electrical stimulation of abdominal muscles (FESAM) could maintain pulmonary ventilation at acceptable levels in individuals with spinal cord injury (SCI) who are unable to breathe spontaneously. This is the first published investigation of this technique in this subject population. This case series study included three individuals with SCI; two were on mechanical ventilation (MV), and one used mechanical ventilation and also had an implanted phrenic nerve stimulator (PNS). ⋯ When oxygenation measured with pulse oximetry dropped to 92% saturation, FESAM was discontinued, and MV or PNS was resumed. This is the first report of achieving successful ventilation in individuals with SCI who have zero tidal volume using FESAM. These preliminary results indicate the clinical potential of FESAM as an additional tool in the armamentarium of supported ventilation.

It was the purpose of this study to retrospectively test the safety and efficacy of the use of intraspinal analgesics in a diverse population of patients with chronic nonmalignant pain. This study was conducted in 39 patients, refractory to conventional therapies for intrathecal therapy. Twenty-two patients had neuropathic pain and 17 had nociceptive pain. ⋯ Other patient-reported side effects were not considered significant by the authors to be mentioned here. After more than 6 years of experience with spinal infusion of morphine, either alone or admixed with other spinal analgesics, in patients with pain of nonmalignant origin, we consider the technique to be helpful in selected patients not responding to oral treatment or when untoward side effects exist with oral treatment. The advantages, as regards to analgesic efficacy and quality of life, clearly outweigh the drawbacks of the long-term use of spinal morphine.
