Specific details are as follows:

I. Effects

1. Analgesia
Lidocaine and chlorhexidine aerosol contains lidocaine, which is a local anesthetic with strong diffusibility and penetration, providing effective pain relief.

2. Antibacterial Action
The aerosol contains acetic acid chlorhexidine, a broad-spectrum antimicrobial agent that exhibits antibacterial activity against both Gram-positive and Gram-negative bacteria.

3. Anti-inflammatory Effect
Lidocaine and chlorhexidine aerosol has antibacterial properties, can inhibit the release of inflammatory mediators, and helps relieve pain and swelling, thereby exerting an anti-inflammatory effect.

4. Treatment of Minor Cuts
Lidocaine and chlorhexidine aerosol is a compound preparation composed of lidocaine, acetic acid chlorhexidine, benzalkonium bromide, and other ingredients, and is effective in treating minor cuts.

5. Treatment of Soft Tissue Injuries
Lidocaine and chlorhexidine aerosol promotes blood circulation and resolves blood stasis, making it suitable for the treatment of soft tissue injuries.

In addition, it can also be used for minor abrasions, burns, and scalds. Patients are advised to use this product under medical supervision and should not self-medicate without guidance.

II. Contraindications

1. Avoid Impact
Lidocaine and chlorhexidine aerosol may explode when exposed to heat or physical impact. It should be stored away from light, heat, freezing temperatures, and physical shock.

2. Avoid Contact with Eyes, Mouth, or Nose
Occasionally, the aerosol may cause skin irritation or a burning sensation. It must not come into contact with the eyes, mouth, or nose. If accidental contact occurs, rinse thoroughly with plenty of water immediately.

3. Do Not Use with Soap
Using lidocaine and chlorhexidine aerosol together with soap may reduce its efficacy, which could impair treatment outcomes. Concurrent use is not recommended.

4. Use with Caution During Pregnancy
The product contains chlorhexidine, a broad-spectrum germicide that may potentially affect the fetus. Pregnant women should use only under the guidance of a qualified physician.

5. Use with Caution in Individuals with Allergic Tendencies
Lidocaine and chlorhexidine aerosol works by blocking nerve transmission to reduce pain sensation. It is not recommended for patients with known allergies or hypersensitivity.

In addition, it should not be used concurrently with saline-based disinfectants. Patients experiencing any discomfort should seek medical attention promptly and receive standardized treatment under a doctor's supervision to facilitate recovery.
