Precise Pain Management: The Application of Handheld Ultrasound in Pain Diagnosis and Treatment
I. Ultrasound-Guided Pain Therapy Techniques
Common visualized pain interventional therapies include: ultrasound-guided injection of local anesthetics, dextrose solution, normal saline or hormones around nerves, tendons and fascia, as well as into joint cavities and muscles; ultrasound-guided insertion of drug delivery systems; and ultrasound-guided radiofrequency ablation or cryotherapy, etc.
II. Indications for Ultrasound-Guided Pain Therapy
1) Chronic soft tissue injury or inflammation: such as lumbar muscle strain, long head of biceps tendinitis, de Quervain’s tenosynovitis, and myofascitis.
2) Local nerve compression: such as carpal tunnel syndrome, sciatica, and lower extremity radiating pain caused by lumbar disc herniation.
3) Osteoarthritis: such as knee joint, cervical zygapophyseal joint, and metacarpophalangeal joint.
4) Local pain caused by systemic inflammatory diseases: such as rheumatoid arthritis and gouty arthritis.Ultrasound-guided precise drug injection technology is a safe and effective method for the treatment of pain disorders. Compared with traditional treatment methods, it has the advantages of minimal invasiveness and rapid onset of action. Under ultrasound guidance, doctors can accurately visualize the location of the lesion and its boundaries with surrounding tissues, and dynamically observe the needle insertion position and the diffusion of the injected drug. Thus, precise injection treatment can be performed on the lesion, and damage to important nerves and blood vessels caused by needle insertion can be effectively avoided.
III. Advantages of the SonoMaxx Handheld Ultrasound in Pain Interventional Therapy
1) Portable and compact, occupying no bedside space; the handheld ultrasound is only the size of a mobile phone, allowing doctors to perform operations directly at the patient’s bedside. It is especially suitable for special patient groups such as the elderly, pregnant women, and children, who can receive treatment in a more relaxed environment.
2) Excellent imaging for precise guidance; though small in size, the handheld ultrasound is “complete in all essential functions” with imaging quality comparable to that of large-scale machines, which can fully meet clinical needs.
Clinical Images of Handheld Ultrasound
3) Central guide line for enhanced puncture; intelligent assisted ultrasound positioning enables more accurate injection. Meanwhile, the SonoMaxx handheld ultrasound supports color Doppler imaging, which is also essential during puncture guidance and can help identify vascular tissues in the operation area.
The great value of ultrasound positioning, highlighted by its operational convenience, real-time performance in guiding puncture, and excellent ability to distinguish soft tissue structures, has been recognized by clinicians. The SonoMaxx handheld ultrasound has obvious application advantages in the Pain Management Department and is worthy of promotion in the clinical practice of pain diagnosis and treatment.
