How does
laser therapy improve vascular circulation in lower limbs?
1. Promote the production of nitric oxide (NO) in the blood, causing capillary dilation, which can increase the blood supply to the affected area.
2. Promote HO-1 synthesis, inhibit inflammatory response and protect cells.
3. Accelerate angiogenesis, improve ischemic wound healing, and reduce pain.
Clinical applications and related literature
1. Wound application: There was a study that randomly divided 60 patients with slow-healing wounds into: a control group and a laser therapy experimental group (both of which had conventional dressing changes and laser therapy therapy can significantly promote the healing of slow-healing wounds.
2. Principle of application for wounds that are difficult to heal due to peripheral artery occlusion in cardiac surgery: The literature points out that vascular surgery first performs vascular reconstruction and then laser treatment 4 times a day for 30 minutes each time. The wound healing is significantly accelerated after use, and the lack of The blood supply to the blood site was significantly restored.
3. Application in thoracic surgery: Relevant literature points out that thoracic surgery takes a long time and is prone to infection. It is most susceptible to infection 3 to 6 days after the operation. The incidence of wound infection is significantly reduced after 7 days of this treatment.
5. Comparison between
laser therapy equipment and general heat therapy equipment
laser therapy instrument
1. It has both thermal and non-thermal effects and can stimulate biological effects of angiogenesis.
2. The temperature is maintained at a constant temperature, easily absorbed by the skin, will not cause burns, and is highly comfortable.
3. It has analgesic and swelling effects, can continuously promote blood circulation and control infection.
Heat therapy equipment (baking lamp, infrared lamp)
1. It only has a thermal effect, which can dilate blood vessels and promote circulation.
2. The temperature cannot be controlled, heat will accumulate on the skin and cause skin burns.
3. It has no pain relief and swelling effect and can only temporarily promote blood circulation.
