العلاج بالضوء الأحمر (rlt) يسرع الشفاء، ولكن التوقيت مهم. البدء في وقت مبكر جدًا بعد الجراحة يمكن أن يتداخل مع التعافي, بينما قد يؤدي الاستخدام المتأخر إلى تفويت نوافذ الشفاء الرئيسية. Here’s astep-by-step guide based on surgical type and expert recommendations.
1. General Timeline by Surgery Type
| Surgery Type | When to Start RLT | الاعتبارات الرئيسية |
|---|---|---|
| Dental/Implants | 24–48 hours post-op | Avoid direct light on fresh incisions; use low intensity. |
| Plastic (Facelift, Rhinoplasty) | 5–7 days (after stitches removed) | Prevent swelling disruption; start with 5-minute sessions. |
| Orthopedic (Knee/Hip Replacement) | 3–5 days (once staples/sutures set) | Focus on reducing inflammation around joints. |
| C-Section/Abdominal | 10–14 days (after wound closure) | Avoid near fresh scars; use only on surrounding areas initially. |
| Laser/Cosmetic Skin | 72 ساعات (once redness subsides) | Test small area first—some lasers increase photosensitivity. |
ملحوظة: Always getsurgeon approval—individual healing rates vary.
2. Benefits of Post-Surgical RLT
✔Faster wound closure (boosts collagen + fibroblasts).
✔Less scar tissue (improves remodeling phase).
✔Reduced pain/swelling (anti-inflammatory effects).
✔Prevents infection (enhances local immune response).
3. How to Safely Use RLT After Surgery
أ. Protocol for Early-Stage Healing (أولاً 2 Weeks)
- الطول الموجي: 660نانومتر (أحمر) for superficial healing; avoid NIR until wounds close.
- مسافة: 12–18 inches from skin (low irradiance: 20–50 mW/cm²).
- مدة: 3–5 minutes per area, 2–3x/day max.
ب. Late-Stage Recovery (3+ Weeks Post-Op)
- Add NIR (850نانومتر): Penetrates deeper to reduce stiffness/scarring.
- Increase to 10 mins/session if no irritation occurs.
ج. المناطق التي يجب تجنبها
- Open wounds or fresh stitches (risk of dehiscence).
- Skin grafts/flaps (wait until fully vascularized).
4. Risks of Starting Too Early
🚫Increased swelling (if used aggressively on fresh trauma).
🚫Delayed clotting (theoretical risk if used immediately post-op).
🚫Scar overheating (with high-power devices on sensitive areas).
استثناء: Some surgeons useintraoperative RLT in controlled settings.
Key Takeaways
✅Start RLT 24h–2 weeks post-op, depending on surgery type.
✅Begin with red light (660نانومتر), then introduce NIR later.
✅قصير, frequent sessions are safer than long exposures.
Always consult your surgeon first—they may adjust timing based on your healing progress.
