Comprehensive Guide to Diaphragm Paralysis: Symptoms, Causes, and Treatment Strategies

The diaphragm, a crucial dome-shaped muscle located between the chest and abdomen, facilitates breathing through rhythmic contractions. Occasionally, this muscle can become paralyzed, affecting its normal function.

What happens in diaphragm paralysis?
The paralyzed diaphragm cannot contract properly, resulting in breathing difficulties.

Common causes involve nerve damage or muscle injury affecting the phrenic nerve, which transmits signals to the diaphragm. Disruption leads to abnormal upward movement during inhalation, reducing lung capacity. Paralysis may be unilateral or bilateral, with bilateral cases causing more significant breathing challenges.

Symptoms of diaphragm paralysis
Breathing issues are primary, especially when both sides are affected, leading to difficulty even at rest. Signs include shortness of breath, especially when lying down, fatigue, repeated pneumonia, and sleep disturbances. Unilateral paralysis often presents as exertional breathing difficulty.

Causes of diaphragm weakness
Damage to the phrenic nerve is common, but other factors include congenital defects, neurological conditions like multiple sclerosis or ALS, traumatic injuries, and illnesses such as cancer or cervical arthritis. In about 40% of cases, the exact cause remains unknown, termed idiopathic.

Diagnostic methods
Imaging techniques such as chest X-rays, ultrasounds, and MRIs aid in diagnosis. Blood tests, including arterial blood gases, evaluate oxygen levels, while pulmonary function tests assess lung capacity and breathing efficiency.

Treatment options for diaphragm paralysis
Approach varies with severity, often beginning with non-invasive therapies. Mild cases benefit from support devices like BiPAP or C-PAP during sleep. Severe cases might require surgery.

Mechanical ventilation support
Support devices like BiPAP help assist breathing, especially during sleep, improving quality of life. Persistent diaphragm failure may necessitate surgical procedures.

Diaphragmatic plication
This procedure involves suturing and tightening the diaphragm to keep it lower, giving the lungs more room to expand. It is less invasive and particularly effective for one-sided paralysis.

Diaphragm pacing devices
Pacing devices stimulate the phrenic nerve to restore movement, especially valuable in spinal injuries or neurodegenerative diseases like ALS.

Phrenic nerve repair
Reconstructing the nerve may enhance function in specific cases, complemented by physical therapy to support respiration.
