Medical Tourniquets Surgical Techniques

🩺 MEDICAL TOURNIQUETS

🔧 DETAILED SURGICAL TECHNIQUE GUIDE

Medical tourniquets are used to control blood flow, providing a bloodless surgical field and improving visualization and precision, especially in limb surgeries.

1. 📋 Preoperative Planning

Indications

• Orthopedic limb surgeries

• Plastic/reconstructive procedures

• Trauma and emergency bleeding control

Contraindications (Relative)

• Severe vascular disease

• Infection at application site

• Sickle cell disease (use caution)

Assessment

• Limb circumference

• Blood pressure

• Skin condition

2. 🛏️ Patient Preparation

• Explain procedure (if conscious)

• Apply padding (soft cotton/foam)

• Select appropriate cuff size:

  • Width should cover sufficient limb area

• Position limb properly

3. 🧷 TYPES OF TOURNIQUETS

• Pneumatic tourniquets (most common in OT)

• Elastic band (Esmarch)

• Mechanical/manual tourniquets

4. 🔧 APPLICATION TECHNIQUE

A. Limb Preparation

Steps:

1. Elevate limb for 2–3 minutes

2. Optional: Apply Esmarch bandage to exsanguinate limb

B. Cuff Placement

Steps:

1. Place cuff proximally on limb

2. Avoid:

   • Bony prominences

   • Nerve compression areas

3. Ensure even wrapping without folds

C. Inflation

Recommended Pressures:

• Upper limb: ~50–100 mmHg above systolic BP

• Lower limb: ~100–150 mmHg above systolic BP

Steps:

1. Inflate cuff to calculated pressure

2. Confirm absence of distal pulse

3. Begin surgery

5. ⏱️ TOURNIQUET TIME MANAGEMENT

Safe Duration:

• Ideal: < 90 minutes

• Maximum: ~120 minutes

If prolonged:

• Deflate for 10–15 minutes

• Reinflate if necessary

6. ⚖️ INTRAOPERATIVE MONITORING

Monitor:

• Tourniquet pressure

• Duration

• Limb condition

Watch for:

• Bleeding (indicates inadequate pressure)

• Pain (in conscious patients)

7. 🔄 DEFLATION TECHNIQUE

Steps:

1. Inform surgical team

2. Gradually deflate cuff

3. Observe:

   • Reperfusion

   • Bleeding control

👉 Be prepared for reactive bleeding.

8. 🧼 POST-APPLICATION CARE

• Inspect skin:

  • Burns

  • Bruising

• Assess:

  • Distal circulation

  • Nerve function

9. ⚠️ COMPLICATIONS & PREVENTION

Complication                                                 Prevention

Nerve injury                                                    Proper padding & pressure

Skin burns                                                      Avoid excessive pressure

Muscle damage                                             Limit duration

Compartment syndrome                               Careful monitoring

Tourniquet pain                                             Adequate anesthesia

10. 🔓 EMERGENCY USE (TRAUMA)

Steps:

1. Apply proximal to bleeding site

2. Tighten until bleeding stops

3. Note time of application

4. Transport patient urgently

11. ✅ KEY SURGICAL PRINCIPLES

• Use correct cuff size

• Apply adequate padding

• Use minimum effective pressure

• Limit application time

• Monitor continuously
