Diaphragm Pacing for Spinal Cord Injury

Diaphragm pacing is a medical procedure used to help individuals with spinal cord injuries (SCIs) breathe more effectively. The diaphragm is the primary muscle responsible for breathing, and in people with SCIs, it may not function properly due to nerve damage.

How it Works

Diaphragm pacing involves the use of an implanted device that stimulates the phrenic nerves, which control the diaphragm. The device consists of a pulse generator, electrodes, and a receiver. The pulse generator is typically implanted under the skin, usually in the chest or abdomen, and produces electrical impulses that stimulate the phrenic nerves.

The electrodes are placed near the phrenic nerves, and the receiver is connected to the pulse generator. When the device is activated, it sends electrical impulses to the phrenic nerves, causing the diaphragm to contract and relax, allowing for breathing.

Benefits

Diaphragm pacing can provide several benefits for individuals with SCIs, including:

• Improved lung function: Diaphragm pacing can help increase lung volume and improve gas exchange, making it easier to breathe.
• Increased independence: By improving breathing, diaphragm pacing can enable individuals with SCIs to perform daily activities with more ease and independence.
• Reduced need for mechanical ventilation: Diaphragm pacing can reduce the need for mechanical ventilation, which can be life-saving for individuals who are dependent on ventilators.
• Improved quality of life: By improving breathing and increasing independence, diaphragm pacing can significantly improve the overall quality of life for individuals with SCIs.

Candidates for Diaphragm Pacing

Diaphragm pacing is typically considered for individuals with SCIs who have:

• High-level spinal cord injuries (above T6)
• Intact phrenic nerves
• Adequate diaphragm function
• No significant lung disease or other medical conditions that would contraindicate the procedure

Risks and Complications

As with any surgical procedure, there are risks and complications associated with diaphragm pacing, including:

• Infection
• Bleeding or hematoma
• Nerve damage
• Device malfunction
• Pain or discomfort at the implant site

Post-Implantation Care and Maintenance

After diaphragm pacing implantation, individuals will require regular follow-up appointments to monitor the device and adjust settings as needed. They will also need to perform daily exercises to maintain diaphragm strength and function.

Additionally, individuals with diaphragm pacers should be aware of potential complications and take steps to prevent them, such as avoiding magnetic fields or other sources of electromagnetic interference that could interfere with the device.
