Foot Ulcers & Cuts — सम्पूर्ण मार्गदर्शिका (Diabetic Foot, Wound Care, Tests, Treatment & Prevention)
यह गाइड विशेषकर डायबिटिक फुट अल्सर, इस्कीमिक ulcers, pressure ulcers और सामान्य कट/घाव के evidence-based प्रबंधन पर केन्द्रित है — शुरुआती देखभाल से लेकर एडवांस्ड थेरेपी तक।
1. परिचय — Foot ulcer क्यों चिंता का विषय है?
Foot ulcers (पैर के घाव) छोटे-छोटे कट से शुरू होकर गंभीर जटिलताओं में बदल सकते हैं—विशेषकर यदि मरीज डायबिटिक है या peripheral arterial disease (PAD) मौजूद हो। delayed healing, infection और osteomyelitis कभी-कभी limb amputation का कारण बन सकते हैं। इसलिए समय पर पहचान, उपयुक्त वाउंड केयर और multidisciplinary management बहुत ज़रूरी है।
2. प्रकार (Types of foot ulcers)
- Diabetic foot ulcer: neuropathy + ischemia + infection का मिश्रण।
- Venous ulcer: ज्यादातर शिरापरक रिटर्न खराब होने पर lower leg पर बनते हैं।
- Arterial / ischemic ulcer: दर्दनाक, गोलाकार ulcers, आमतौर पर toes/pressure points पर।
- Pressure (decubitus) ulcer): immobile मरीजों में लगातार दबाव की वजह से बनते हैं।
- Traumatic cuts & lacerations: घाव जो तुरंत संक्रमित हो सकते हैं अगर साफ-सफाई/ड्रेसिंग न की जाए।
3. जोखिम कारक (Risk factors)
- Diabetes mellitus (neuropathy, poor glycemic control)
- Peripheral arterial disease (PAD)
- Previous foot ulcer or amputation
- Foot deformities, ill-fitting shoes
- Smoking, malnutrition, renal disease, immunosuppression
4. पैथोलॉजी (How ulcers develop)
Diabetic neuropathy से sensory loss होता है—अर्थात मरीज को चोट/घर्षण का पता नहीं चलता; साथ में peripheral arterial disease होने पर blood supply कम होने से healing impaired रहती है। बार-बार दबाव वाले स्थानों पर callus बनकर धीरे-धीरे ulcer बनता है। अगर infection जुड़ जाए तो tissue destruction और bone involvement (osteomyelitis) तक पहुंच सकती है।
5. Presentation — लक्षण और संकेत
- घाव का दिखना: open wound, base पर necrotic tissue, pus या serous discharge
- समारोह में परिवर्तन: redness, warmth (infection); या pale/cold foot (ischemia)
- न्यूरोपैथिक मरीजों में numbness, paresthesia
- स्थिर दर्द या claudication — PAD का संकेत
- अचानक बुखार, systemic signs — severe infection का संकेत
Diabetic patients में कोई भी नया ulcer या घाव तुरंत clinician को दिखाएँ — क्योंकि शुरुआत में दर्द कम हो सकता है और स्थिति भयावह बन सकती है।
6. डायग्नोसिस और आवश्यक टेस्ट
सही diagnosis के लिए clinical exam के साथ targeted investigations चाहिए:
- Clinical wound assessment: size, depth, base (granulation/necrosis), surrounding cellulitis.
- Neuropathy testing: 10g monofilament, vibration perception (tuning fork), reflexes.
- Vascular assessment: palpate dorsalis pedis/posterior tibial pulses; Ankle-Brachial Index (ABI) — ABI ≤0.9 suggests PAD.
- Wound swab / tissue culture: deep tissue sample preferred over superficial swab when possible — guide antibiotic therapy.
- Blood tests: HbA1c, CBC, CRP/ESR (infection/inflammation), renal function, electrolytes.
- Imaging: X-ray foot (to rule out gas or bony involvement), MRI (if osteomyelitis suspected), vascular doppler/CT angiography for revascularization planning.
- Biopsy: atypical or non-healing ulcers to exclude malignancy.
7. Classification / Grading (useful for management)
कई grading systems हैं — Wagner और University of Texas (UT) commonly used।
उदाहरण: Wagner grade 0–5 (0 high-risk foot; 1 superficial ulcer; 3 deep abscess/osteomyelitis; 4–5 gangrene)।
8. Treatment — stepwise and evidence-based
Management principles: Control infection, remove devitalized tissue (debridement), ensure adequate perfusion, offload pressure, and optimize systemic factors (nutrition, glucose control).
8.1 Initial stabilization and resuscitation
- Assess ABCs in severe infection; fluid balance, glycemic control, analgesia.
- Start systemic antibiotics if systemic signs or severe local infection — but tailor to culture results.
8.2 Debridement
Necrotic tissue removal accelerates healing and reduces bacterial load. Methods:
- Sharp/surgical debridement (most rapid)
- Autolytic debridement (moist dressings)
- Enzymatic debridement
- Mechanical debridement (as indicated)
8.3 Dressings & wound environment
Maintain a moist, clean wound environment. Dressing choice depends on exudate level and infection status:
- Low exudate: hydrocolloid, semi-permeable film
- Moderate–high exudate: foam, alginate
- Infected wounds: antimicrobial dressings (silver-impregnated) and systemic antibiotics
- Periodic reassessment and dressing changes by trained personnel
8.4 Offloading (pressure redistribution)
Offloading is crucial for plantar ulcers — options include:
- Total contact cast (gold standard for plantar neuropathic ulcers)
- Removable cast walkers, custom orthotics, cushioned insoles
- Education to limit weight-bearing and provide protective footwear
8.5 Antibiotics
Systemic antibiotics should be started based on severity and culture results. Common empiric choices (local resistance patterns guide final choice):
- For mild infection: oral agents covering Gram + cocci (e.g., amoxicillin-clavulanate or cephalexin if MSSA likely)
- Moderate–severe: cover MSSA, streptococci and Gram-negative organisms; consider MRSA coverage (vancomycin/linezolid) based on risk
- Deep tissue/osteomyelitis: prolonged IV therapy guided by culture and imaging findings
(Always de-escalate based on culture & sensitivity.)
8.6 Vascular intervention
यदि PAD मौजूद है और perfusion compromised है, revascularization (angioplasty with/without stenting or surgical bypass) से healing dramatically improve हो सकता है। Vascular surgeon से early consult ज़रूरी।
8.7 Advanced and adjunct therapies
- Negative pressure wound therapy (NPWT / VAC)
- Topical growth factors, platelet-rich plasma (PRP)
- Skin grafting or flap coverage for large defects
- Hyperbaric oxygen therapy (selected cases, e.g., refractory osteomyelitis)
8.8 Surgical indications
- Extensive necrosis, uncontrolled sepsis, gas in tissues, frank osteomyelitis with failure of conservative therapy
- Critical limb ischemia not amenable to revascularization may require amputation to control infection
9. Medicines — आम दवाइयाँ और सावधानियाँ
- Empiric antibiotics: Amoxicillin-clavulanate, Cephalexin, Doxycycline (mild). For moderate–severe: Piperacillin-tazobactam, cefepime + metronidazole, or carbapenems as per local policy.
- MRSA coverage: Vancomycin, Linezolid, Daptomycin (based on culture & risk).
- Analgesics: Paracetamol preferred; NSAIDs caution in renal disease and bleeding risk.
- Topicals: Antiseptic washes (chlorhexidine), silver dressings — use as per wound status.
Dose adjustments required in renal/liver impairment; pregnancy considerations for certain antibiotics. Hamesha culture-guided therapy best practice है।
10. Nutrition & Diet — घाव भरने में आहार का रोल
किसी भी वाउंड के इलाज में पोषण की भूमिका बहुत बड़ी है — विशेषकर protein और micronutrients के मामले में।
- Protein: 1.2–1.5 g/kg body weight/day to support collagen synthesis and repair.
- Calories: Adequate caloric intake to prevent catabolism.
- Micronutrients: Vitamin C (collagen formation), Zinc (cell proliferation), Vitamin A, Iron (if anemic), Vitamin D (immune modulation & healing).
- Hydration: Adequate fluids to support perfusion and renal function.
Recommended foods
- Lean proteins: eggs, pulses, fish, poultry (as tolerated)
- Dairy: low-fat milk, yogurt
- Fruits/vegetables rich in vitamin C: citrus, guava, amla, bell peppers
- Whole grains and healthy fats (nuts, seeds — salt-free)
Foods to avoid / limit
- Excess refined sugar (especially in diabetics), heavy fried foods, excessive alcohol
- High-sodium processed foods (can worsen edema and hypertension)
Sample day meal plan (healing-focused)
सुबह: ओट्स + पका फल + 1 अंडा / दही
दोपहर: ब्राउन राइस/रोटी + दाल + हरी सब्जी + सलाद
शाम: sprouts/roasted chana
रात: हल्की खिचड़ी/सूप + सब्जी + दही
11. Prevention — रोज़मर्रा की आदतें
- Daily foot inspection: morning और रात में दोनों — छोटे cuts, blisters, redness तुरन्त नोट करें
- Proper footwear: cushioned, wide toe-box, avoid barefoot
- Toenail care: straight cut, avoid aggressive cutting in diabetics — podiatrist help if needed
- Glycemic control: HbA1c target individualized; frequent glucose monitoring
- Smoking cessation and exercise to improve circulation
12. Home care — छोटे कट/छाले में क्या करें?
- घाव को साबुन और पानी से हल्के से धोएं; साफ़ कपड़े से सुखाएँ।
- If no deep wound and no signs of infection — apply sterile dressing and monitor daily.
- Avoid traditional irritants (hot ash, kohl, unclean pastes).
- If signs of infection (redness, pus, fever), seek medical care immediately.
13. Red flags — तुरंत डॉक्टर को दिखाएँ
- Rapidly spreading redness, increasing pain, fever or chills
- Foul-smelling discharge, necrosis or black tissue
- Loss of pulses, cold/pale foot — ischemia
- Non-healing ulcer despite appropriate care (4 weeks+) or progressive size increase
इन संकेतों पर देर न करें — delayed care limb loss का कारण बन सकती है।
14. Multidisciplinary care — कौन-कौन चाहिए?
- Primary care physician / endocrinologist (glycemic control)
- Podiatrist / wound care nurse
- Vascular surgeon / interventional radiologist (for revascularization)
- Infectious disease specialist (complex infections)
- Orthopedic surgeon (if osteomyelitis or bone involvement)
- Dietitian and physiotherapist (offloading / rehab)

17. Prognosis & expected course
Superficial neuropathic ulcers with good offloading and glycemic control may heal in weeks to months. Ulcers with ischemia, osteomyelitis, or deep infection have prolonged courses and increased risk of amputation. Early multidisciplinary care improves limb salvage rates substantially.
18. निष्कर्ष
Foot ulcers और cuts का प्रभावी प्रबंधन early detection, appropriate wound care (debridement + moist dressings), infection control, offloading और systemic optimization (nutrition, glycemic control, vascular status) पर निर्भर करता है। किसी भी नए घाव/न बढ़ने वाले घाव/सिस्टमिक संकेत पर तुरंत विशेषज्ञ से संपर्क करें।
