![]() Recharging a rechargeable neurostimulator may result in skin irritation or redness near the implant site. Avoid activities that put stress on the implanted neurostimulation system components. Safety and effectiveness has not been established for pediatric use, pregnancy, unborn fetus, or delivery. A preoperative assessment is advised for some patients with diabetes to confirm they are appropriate candidates for surgery. Patients with diabetes may have more frequent and severe complications with surgery. An implanted cardiac device (e.g., pacemaker, defibrillator) may damage a neurostimulator, and electrical pulses from the neurostimulator may cause inappropriate response of the cardiac device. Sources of electromagnetic interference (e.g., defibrillation, electrocautery, MRI, RF ablation, and therapeutic ultrasound) can interact with the system, resulting in unexpected changes in stimulation, serious patient injury or death. The company is also seeking approval to carry out a similar trial in the United States.Spinal cord stimulation (SCS) is indicated as an aid in the management of chronic, intractable pain of the trunk and/or limbs-including unilateral or bilateral pain.ĭiathermy - Energy from diathermy can be transferred through the implanted system and cause tissue damage resulting in severe injury or death. "We anticipate that this new system may be a lot more effective over a long term."Ībout 30 patients will be recruited to trial the device. "At the moment we calculated the cost of the neurostimulation system is recouped in about two-and-a-half years but that's with existing systems. "A study done by the Pain Management Research Institute and Access Economics estimated $35 billion a year and a lot of that could be saved," he said. Professor Cousins said this device could offer chronic pain sufferers an alternative to pain-killer medications. One-in-five Australians suffers chronic pain and it is estimated to cost more than $30 billion a year. "This will lead to great improvements in spinal cord stimulation treatment but also has a potential for big improvements in the nervous system for other conditions in addition to chronic pain," he said. Professor Michael Cousins, the director of the Pain Management Research Institute at the Royal North Shore Hospital and University of Sydney, said the device could have wider applications and could eventually be used for patients with Parkinson's disease. "The next thing to do will be to switch the feedback system on so that when he's walking around and doing his normal activities he gets really nice, smooth, consistent stimulation." Device could offer an alternative to pain-killer medication ![]() "He said the device is working well covering his pain area. "I saw him this morning, he's very happy, he's a little bit sore from the surgery," he said. "So this device is a big advance as it records the signal coming back out of the nervous system."ĭr Brooker said the surgery on Mr Grewal appears to have been a success. "So that means a machine can adjust itself to produce whatever set level the patient wants, and that's a big advance because previously, whenever people moved or their heart was pulsating, various things would make the electrical signal waver up and down quite significantly and they would get shock sensations and not being able to live their lives effectively in many cases. "It sends signals into the spinal cord and so the person with pain feels tingling in the pain area and that confuses the brain and they don't feel the pain, they just feel a pleasant tingling sensation."ĭr Brooker said unlike previous spinal cord stimulators, this new technology sends signals back from the body to help guide treatment. "Spinal cord stimulators have been around for 20 to 30 years, which involve a wire sitting just outside the spinal cord, connected to a battery with a computer, just like a pacemaker really," he said. The spinal cord stimulator, which sends electrical pulses to replace pain sensations, was fitted by the Royal North Shore Hospital's pain specialist Dr Charles Brooker. "I feel amazing actually," he told Channel 9. He has tried everything from back surgery to a morphine implant.ĭoctors implanted the device yesterday to help relieve some of his pain. The first recipient was 60-year-old Joe Grewal, who has been suffering chronic back pain for more than 30 years. The doctors said the Saluda device could also help patients with other nerve conditions, including Parkinson's disease. Doctors at the Royal North Shore Hospital have fitted a patient with a spinal cord stimulator that sends out electrical currents through the nerves to provide pain relief in a world-first procedure.
