Crush Injury / Crush Syndrome — বাংলা ক্লিনিক্যাল গাইড
জরুরি সতর্কতা: Crush injury হলে রোগী দেখতে “stable” থাকলেও চাপ সরানোর পর হঠাৎ hyperkalemia, shock, cardiac arrest, acute kidney injury হতে পারে। তাই এটি hospital emergency। নিচের dose adult general guide; বাস্তবে vitals, renal function, K⁺, ECG, wound status অনুযায়ী doctor adjust করবেন।
1. Definition
Crush injury হলো শরীরের কোনো অংশ দীর্ঘক্ষণ বা তীব্রভাবে চাপে আটকে গিয়ে muscle, soft tissue, blood vessel, nerve বা bone-এর local injury ও ischemia হওয়া। বড় muscle mass যেমন thigh, calf, buttock, chest/torso আক্রান্ত হলে চাপ সরানোর পর muscle breakdown products রক্তে ছড়িয়ে crush syndrome তৈরি করতে পারে, যা life-threatening systemic condition।
Crush syndrome-এর core pathology: muscle necrosis → rhabdomyolysis → myoglobin, potassium, phosphate, lactate release → AKI + hyperkalemia + metabolic acidosis + arrhythmia। INSARAG guideline অনুযায়ী প্রধান acute concerns হলো hypovolaemia, hyperkalemia, metabolic acidosis ও AKI; delayed concerns হলো renal failure, ARDS, coagulopathy ও severe sepsis।
2. Causes / কারণ
- Building collapse / earthquake / wall বা beam চাপা পড়া
- Road traffic accident: গাড়ির নিচে limb আটকে যাওয়া, heavy vehicle trauma
- Industrial / construction injury: machine, roller, lift, press machine, crane load
- Heavy object fall: গাছ, পাথর, ইট, লোহার রড, concrete slab
- Prolonged immobilization: অজ্ঞান হয়ে দীর্ঘক্ষণ এক পাশে পড়ে থাকা, alcohol/drug overdose, stroke/seizure-এর পর পড়ে থাকা
- Blast / war injury / assault
- Farm injury: tractor, harvester, heavy agricultural equipment
- Electrical burn / severe burn: muscle damage + rhabdomyolysis হতে পারে
Risk বেশি যখন compression ১ ঘণ্টা বা বেশি, proximal limb/buttock/torso জড়িত, large muscle mass crushed, dehydration/shock আছে, বা release-এর আগে IV fluid দেওয়া যায়নি।
3. Symptoms / Clinical Features
Local symptoms
- আক্রান্ত limb/area-তে severe pain, তবে pain কম হলেও injury severe হতে পারে
- Swelling, tightness, tense compartment
- Skin: bruised, pale, mottled, blistered, crushed wound
- Numbness, tingling, burning sensation, anaesthesia
- Weakness / paralysis / movement কমে যাওয়া
- Pulse কম/না পাওয়া, capillary refill slow, limb cold
- Fracture, open wound, bleeding, deformity
Systemic symptoms
- Dark reddish-brown urine / tea-coloured urine
- Urine output কমে যাওয়া
- Tachycardia, hypotension, dizziness, shock
- Palpitation, ECG abnormality—hyperkalemia হলে
- Confusion, restlessness, weakness
- Nausea, vomiting, severe thirst
INSARAG clinical presentation-এ mottled/blistered/bruised/pale skin, edema, poor perfusion, shock, reddish-brown urine, sensory loss, pain, motor loss ও decreased urine output উল্লেখ আছে।
4. Clinical Diagnosis
Crush injury diagnosis মূলত history + examination + renal/electrolyte monitoring দিয়ে করা হয়।
History
- কতক্ষণ চাপা ছিল?
- কোন body part চাপা ছিল?
- চাপ সরানোর আগে/পরে deterioration হয়েছে কি?
- urine colour ও urine amount
- open wound, fracture, bleeding, burn আছে কি?
Examination
- ABCDE trauma assessment
- Vitals: BP, pulse, respiratory rate, SpO₂, temperature
- Limb neurovascular exam: pain, pulse, sensation, movement, capillary refill
- Compartment syndrome signs:
- pain out of proportion
- passive stretch pain
- tense swollen compartment
- paresthesia, weakness
- late sign: pulselessness/paralysis
Rhabdomyolysis clue
AAST consensus অনুযায়ী rhabdomyolysis laboratory finding হিসেবে CK > 5× upper limit of normal বা >1000 IU/L ধরা হয়। Fluid target সাধারণত urine output 1–3 mL/kg/hour, সর্বোচ্চ 300 mL/hour।
5. Investigations
Emergency bedside
- ECG: peaked T wave, widened QRS, bradycardia → hyperkalemia suspicion
- Urinary catheter: hourly urine output monitor
- Pulse oximetry + BP monitoring
- Pain score + repeated neurovascular charting
Blood tests
- CBC
- Blood group, crossmatch
- Serum electrolytes: K⁺, Na⁺, Ca²⁺, phosphate, magnesium
- Urea, creatinine, eGFR
- Creatine kinase / CK serial 6–12 hourly
- ABG/VBG: metabolic acidosis
- Serum lactate
- LFT: AST/ALT may rise due to muscle injury
- Coagulation profile: PT/INR, aPTT, fibrinogen if DIC suspected
- CRP, wound culture/blood culture if infection/sepsis suspected
Urine tests
- Urine R/E
- Urine dipstick: blood positive but RBC কম → myoglobinuria suspicion
- Urine myoglobin if available
Imaging
- X-ray of injured limb/pelvis/spine
- FAST/eFAST in polytrauma
- CT trauma series if indicated
- Doppler US / CT angiography if vascular injury suspected
- Compartment pressure measurement if diagnosis unclear or patient unconscious
6. Differential Diagnosis
- Acute compartment syndrome
- Acute limb ischemia / arterial injury
- Fracture-dislocation
- Spinal cord injury / peripheral nerve injury
- Necrotizing fasciitis
- Cellulitis with severe swelling
- DVT
- Burn/electrical injury-related rhabdomyolysis
- Drug-induced rhabdomyolysis
- Heat stroke / seizure-induced rhabdomyolysis
7. Complications — বাংলা ব্যাখ্যা
- Acute kidney injury: muscle থেকে myoglobin বের হয়ে kidney tubule block ও toxic damage করে; urine কমে যায়, creatinine বাড়ে।
- Hyperkalemia: damaged muscle থেকে potassium বের হয়; ECG change, arrhythmia, cardiac arrest হতে পারে।
- Hypovolemic shock: crushed tissue-তে fluid sequestration হয়, circulating blood volume কমে যায়।
- Metabolic acidosis: tissue ischemia ও renal failure-এর কারণে acid জমে যায়।
- Compartment syndrome: limb-এর ভিতরে pressure বেড়ে muscle/nerve blood supply বন্ধ হয়ে যায়; জরুরি fasciotomy লাগতে পারে।
- Infection / sepsis / gangrene: open contaminated wound হলে bacteria ঢুকে severe infection করতে পারে।
- Tetanus: crush wound dirty/major wound হিসেবে tetanus risk বাড়ায়। CDC crush injuries-কে dirty/major wound category-তে রেখেছে।
- DIC / coagulopathy: severe trauma ও sepsis থেকে clotting system fail করতে পারে।
- ARDS: severe systemic inflammation/sepsis থেকে lung failure হতে পারে।
- Amputation / death: uncontrolled infection, vascular injury বা unsalvageable limb হলে।
8. Treatment / Management
A. Immediate non-pharmacological management
- Scene safety নিশ্চিত করা।
- ABCDE trauma care.
- High-flow oxygen if hypoxic/shock.
- Active bleeding control; tourniquet শুধু life-threatening uncontrolled bleeding হলে। INSARAG routine tourniquet discourage করে কারণ perfusion আরও খারাপ হতে পারে।
- Limb realign + splint.
- Ring, tight cloth, shoe খুলে দেওয়া।
- Open fracture হলে wound ঘষাঘষি/mini-washout না করে saline-soaked sterile dressing + occlusive cover। NICE ও BOAST open fracture-এ early IV antibiotic, saline-soaked dressing, neurovascular documentation ও specialist transfer recommend করে।
- IV fluid preferably before release/extrication: fluid therapy crush syndrome management-এর cornerstone।
- Foley catheter দিয়ে urine output monitor.
- Repeated ECG + K⁺ monitoring.
- Surgical debridement, fracture fixation, vascular repair, fasciotomy—hospital decision.
- Dialysis if refractory hyperkalemia, severe acidosis, volume overload, uremic complications, persistent anuria/AKI.

1. Overview / Summary
Crush injury হলো compression-induced muscle/soft tissue injury। বড় muscle mass crushed হলে release-এর পর rhabdomyolysis, hyperkalemia, metabolic acidosis, shock ও AKI হয়ে crush syndrome তৈরি হয়। Core treatment হলো early ABCDE trauma care, bleeding control, splinting, IV fluid before/after release, ECG/K⁺/CK/renal monitoring, open wound antibiotic/tetanus prophylaxis, এবং প্রয়োজন হলে surgery/dialysis।
2. Actionable Plan / Steps
- Crush injury suspected হলে immediately hospital/ER.
- Release/extrication-এর আগে সম্ভব হলে IV 0.9% saline শুরু।
- ECG + serum K⁺ + creatinine + CK + urine output monitor।
- Open wound/fracture হলে sterile saline dressing, splint, early IV antibiotic, tetanus prophylaxis।
- Hyperkalemia ECG change হলে calcium gluconate + insulin-dextrose + salbutamol emergency protocol।
- AKI, acidosis, anuria, volume overload হলে nephrology/dialysis consult।
- Compartment syndrome signs থাকলে urgent orthopedic/surgical evaluation।

General Quaries of this topics:-
Question No 1. ABCDE trauma assessment kake bole example die bujie bolo?
ABCDE Trauma Assessment কাকে বলে?
ABCDE trauma assessment হলো trauma বা emergency patient-কে দ্রুত পরীক্ষা করার একটি step-by-step primary survey। এর উদ্দেশ্য হলো যে সমস্যাগুলো patient-কে মিনিটের মধ্যে মারা ফেলতে পারে, সেগুলো আগে খুঁজে বের করে সাথে সাথে treat করা। ABCDE মানে: Airway, Breathing, Circulation, Disability, Exposure। এটি critically ill বা injured patient-এর immediate assessment and treatment-এর জন্য widely used systematic approach।
A = Airway with cervical spine protection
অর্থ: শ্বাসনালী খোলা আছে কি না?
প্রথমে দেখতে হবে patient কথা বলতে পারছে কি না, গলায় রক্ত/বমি/দাঁত/মাটি/বিদেশি বস্তু আটকে আছে কি না। Trauma patient হলে neck injury থাকতে পারে, তাই airway দেখার সময় cervical spine protect করতে হয়।
কী দেখবেন:
- Patient কথা বলতে পারছে?
- গলায় ঘড়ঘড় শব্দ, snoring, gurgling আছে?
- মুখে রক্ত/বমি/ভাঙা দাঁত আছে?
- জিহ্বা পেছনে পড়ে airway বন্ধ করছে কি?
কী করবেন:
- Suction দিয়ে blood/vomit পরিষ্কার
- Jaw thrust maneuver
- Oropharyngeal/nasopharyngeal airway
- Severe case হলে intubation
NICE major trauma guideline-এ major trauma patient airway maintain করতে না পারলে RSI/intubation definitive airway হিসেবে recommend করা হয়েছে।
Example:
Crush injury patient building collapse থেকে এসেছে। সে কথা বলতে পারছে না, মুখে রক্ত ও বমি আছে, গলায় ঘড়ঘড় শব্দ। এখানে প্রথম কাজ হবে airway clear করা + neck immobilization।
B = Breathing
অর্থ: patient ঠিকমতো শ্বাস নিচ্ছে কি না?
Airway খোলা থাকলেও lung/chest injury থাকলে oxygen body-তে যাবে না। তাই chest movement, respiratory rate, SpO₂, breath sound দেখতে হয়।
কী দেখবেন:
- Respiratory rate কত?
- SpO₂ কত?
- Chest সমানভাবে উঠানামা করছে কি?
- Breath sound দুই পাশে সমান কি?
- Chest wound, rib fracture, flail chest, tension pneumothorax আছে কি?
কী করবেন:
- Oxygen দেওয়া
- Chest auscultation
- Tension pneumothorax হলে urgent needle decompression/chest drain
- Severe breathing failure হলে ventilation support
Example:
Patient-এর left chest চাপা পড়েছে। SpO₂ 82%, respiratory rate 34/min, left side breath sound কম। এখানে Breathing problem suspect করতে হবে—pneumothorax/hemothorax/rib fracture হতে পারে।
C = Circulation with haemorrhage control
অর্থ: রক্ত চলাচল ঠিক আছে কি না, bleeding আছে কি না?
Trauma patient-এর সবচেয়ে common preventable death cause হলো severe bleeding/shock। তাই pulse, BP, skin perfusion, capillary refill, external bleeding, internal bleeding suspicion দেখতে হবে। Trauma primary survey দ্রুত life-threatening injuries যেমন airway obstruction, respiratory failure, massive haemorrhage ও brain injury identify করতে design করা হয়েছে।
কী দেখবেন:
- Pulse fast/weak?
- BP কম?
- Skin ঠান্ডা, ঘামছে, pale?
- Capillary refill >2 sec?
- External bleeding আছে?
- Abdomen/pelvis/thigh injury থেকে internal bleeding হতে পারে কি?
কী করবেন:
- Direct pressure দিয়ে bleeding control
- Two large-bore IV cannula
- IV fluid/blood transfusion as indicated
- Pelvic binder if pelvic fracture suspected
- Crush syndrome হলে early IV normal saline
- ECG monitor
Example:
Leg crush injury patient-এর thigh ফুলে গেছে, pulse 130/min, BP 80/50, skin cold clammy। এখানে Circulation failure/shock—bleeding control + IV access + fluid/blood + urgent surgery consult লাগবে।
D = Disability
অর্থ: brain, nerve, spinal cord status কেমন?
এখানে neurological assessment করা হয়। মাথায় আঘাত, hypoxia, shock, hypoglycemia বা spinal injury আছে কি না বোঝা যায়।
কী দেখবেন:
- Conscious level: AVPU
- A = Alert
- V = Voice-এ response
- P = Pain-এ response
- U = Unresponsive
- GCS score
- Pupil size/reactivity
- Limb movement/sensation
- Blood glucose
কী করবেন:
- Low glucose হলে glucose correct
- Seizure হলে management
- Head injury suspicion হলে CT brain
- Spinal injury suspicion হলে immobilization
Example:
Patient প্রথমে কথা বলছিল, পরে confused হয়ে যাচ্ছে। GCS 13 থেকে 9 হয়ে গেছে, pupil unequal। এখানে Disability problem—head injury/brain bleed suspect করে urgent CT + neurosurgical assessment দরকার।
E = Exposure / Environment control
অর্থ: পুরো শরীর দেখে injury খুঁজে বের করা, কিন্তু hypothermia prevent করা
Trauma patient-এর injury কাপড়ের নিচে লুকানো থাকতে পারে। তাই পুরো body expose করে দেখতে হয়, কিন্তু patient ঠান্ডা হয়ে গেলে clotting problem ও shock worse হয়।
কী দেখবেন:
- মাথা থেকে পা পর্যন্ত wound, burn, deformity
- Back, buttock, axilla, perineum
- Open fracture
- Compartment swelling
- Crush mark
- Body temperature
কী করবেন:
- Clothes cut করে full examination
- Warm blanket
- Warm IV fluid if possible
- Wound cover
- Recheck ABCD repeatedly
Example:
Patient-এর শুধু পায়ের injury দেখা যাচ্ছিল, কিন্তু expose করার পর back side-এ বড় laceration ও active bleeding পাওয়া গেল। তাই Exposure না করলে hidden injury miss হতে পারে।
Crush Injury দিয়ে Full Example
একজন রোগী construction site-এ concrete slab-এর নিচে ২ ঘণ্টা চাপা ছিল।
A — Airway
রোগী কথা বলছে কিন্তু কাশি দিয়ে রক্ত বের হচ্ছে।
Meaning: airway currently patent, but blood aspiration risk আছে।
Action: suction ready, cervical spine protection।
B — Breathing
RR 30/min, SpO₂ 88%, chest pain।
Meaning: chest injury/pneumothorax/contusion হতে পারে।
Action: oxygen, chest auscultation, chest X-ray/eFAST।
C — Circulation
Pulse 125/min, BP 90/60, right thigh swollen, urine dark।
Meaning: shock + rhabdomyolysis/crush syndrome risk।
Action: 2 IV line, normal saline, blood tests: K⁺, creatinine, CK, ECG, catheter।
D — Disability
GCS 15, pupil equal, limb sensation কম।
Meaning: head injury আপাতত কম likely, কিন্তু nerve/compartment problem হতে পারে।
Action: neurovascular monitoring, compartment syndrome assess।
E — Exposure
Full body check করলে calf tense swelling, skin blister, open wound পাওয়া গেল।
Meaning: severe crush injury + infection/tetanus risk।
Action: sterile dressing, antibiotics, tetanus prophylaxis, orthopedic surgery consult।
সহজ shortcut মনে রাখার জন্য
A — Airway: গলা খোলা?
B — Breathing: শ্বাস চলছে? oxygen যাচ্ছে?
C — Circulation: bleeding/shock আছে?
D — Disability: মাথা/nerve ঠিক আছে?
E — Exposure: পুরো শরীর দেখে hidden injury খুঁজুন, ঠান্ডা লাগতে দেবেন না।
Overview / Summary
ABCDE trauma assessment হলো trauma patient-এর primary survey, যেখানে সবচেয়ে life-threatening problem আগে দেখা ও treat করা হয়। Order হলো Airway → Breathing → Circulation → Disability → Exposure, কিন্তু real emergency-তে team একসাথে অনেক কাজ করে এবং বারবার reassessment করে।
Actionable Plan / Steps
- Trauma patient এলে আগে ABCDE করুন।
- Airway blocked হলে আগে airway clear করুন।
- Breathing problem হলে oxygen/chest emergency manage করুন।
- Circulation problem হলে bleeding control + IV line + fluid/blood দিন।
- Disability-তে GCS, pupil, glucose দেখুন।
- Exposure করে hidden injury খুঁজুন, কিন্তু hypothermia prevent করুন।
- প্রতিটি intervention-এর পর আবার ABCDE repeat করুন।
Question No 2. Rhabdomyolysis clue kake bole bujie dau?
Rhabdomyolysis clue কাকে বলে?
Rhabdomyolysis clue মানে হলো এমন লক্ষণ, history বা test finding, যেগুলো দেখে doctor সন্দেহ করেন যে patient-এর muscle ভেঙে রক্তে muscle protein/enzyme বের হচ্ছে। Crush injury-তে এটা খুব গুরুত্বপূর্ণ, কারণ rhabdomyolysis থেকে acute kidney injury, hyperkalemia, arrhythmia হতে পারে। AAST consensus অনুযায়ী rhabdomyolysis diagnosis-এ সাধারণত CK > 5 times upper limit of normal বা >1000 IU/L গুরুত্বপূর্ণ laboratory clue।
সহজ ভাষায় বুঝুন
ধরুন, একজন patient concrete slab-এর নিচে ২ ঘণ্টা পা চাপা পড়ে ছিল। বাইরে থেকে শুধু পা ফুলে গেছে মনে হচ্ছে। কিন্তু ভিতরে muscle cell ভেঙে গেছে। চাপ সরানোর পর muscle থেকে myoglobin, potassium, CK রক্তে চলে আসে। তখন urine কালচে হতে পারে, potassium বেড়ে heart problem হতে পারে, আর myoglobin kidney damage করতে পারে। এই অবস্থা সন্দেহ করার লক্ষণগুলোকেই বলা হয় rhabdomyolysis clue।
Important Rhabdomyolysis Clues
1. History clue
- Crush injury / heavy object চাপা পড়া
- দীর্ঘক্ষণ limb/body compressed থাকা
- অজ্ঞান হয়ে অনেকক্ষণ একই জায়গায় পড়ে থাকা
- severe exercise/heat stroke
- seizure
- electrical burn
- drug/alcohol intoxication
- statin বা কিছু drug use
Trauma, crush injury, compartment syndrome এবং prolonged immobilization rhabdomyolysis-এর high-risk situation হিসেবে উল্লেখ করা হয়েছে।
2. Symptom clue
- Muscle pain / severe body pain
- Muscle swelling
- Muscle weakness
- Limb tight/tense feeling
- Dark urine / tea-coloured urine / cola-coloured urine
- Urine কমে যাওয়া
- Weakness, nausea, vomiting, dizziness
Classic triad হলো muscle pain + weakness + dark urine, কিন্তু এই তিনটি একসাথে সব patient-এ থাকে না। তাই symptoms না থাকলেও crush injury patient-এ lab test জরুরি। StatPearls-এ common symptoms হিসেবে myalgia, weakness, dark urine ও local swelling উল্লেখ আছে।
3. Urine clue
সবচেয়ে important bedside clue:
- Urine tea/cola colour
- Urine dipstick এ blood positive, কিন্তু microscopy-তে RBC কম বা নেই
কেন এমন হয়?
Urine dipstick myoglobin আর hemoglobin দুটোকেই “blood” হিসেবে ধরতে পারে। Rhabdomyolysis-এ muscle থেকে myoglobin বের হয়ে urine dark করে। Cleveland Clinic-ও muscle pain/weakness/stiffness-এর সাথে pee colour change-কে common sign হিসেবে উল্লেখ করেছে।
4. Blood test clue
- CK / CPK very high
- সাধারণ clue: CK >1000 IU/L বা normal-এর ৫ গুণের বেশি
- Severe case-এ CK 5000, 10000 বা আরও বেশি হতে পারে
- Serum potassium high
- Creatinine/urea বাড়তে পারে
- Phosphate বাড়তে পারে
- Calcium initially কমতে পারে
- AST/ALT বাড়তে পারে, কারণ muscle থেকেও AST/ALT বের হয়
- Metabolic acidosis থাকতে পারে
AAST consensus বলছে CK সাধারণত injury-এর ১২ ঘণ্টার মধ্যে বাড়ে, ২৪–৭২ ঘণ্টায় peak করে, পরে ধীরে কমে।
Real example
একজন ৩৫ বছর বয়সী construction worker-এর right leg ৩ ঘণ্টা concrete-এর নিচে চাপা ছিল।
Patient-এর finding:
- পা ফুলে গেছে, ব্যথা বেশি
- urine কালচে
- BP একটু কম
- CK = 12,000 IU/L
- K⁺ = 6.2 mmol/L
- Creatinine বাড়ছে
- ECG-তে peaked T wave
Meaning:
এগুলো strong rhabdomyolysis clues।
এখানে শুধু painkiller দিলে হবে না। দরকার:
- IV normal saline
- ECG monitoring
- potassium emergency management
- urine output monitoring
- renal function monitoring
- possible dialysis if refractory hyperkalemia/AKI
Shortcut মনে রাখুন: “3 Dark + 3 High”
3 Dark
- Dark urine
- Dark history: crush/prolonged compression
- Dark danger: kidney failure risk
3 High
- High CK
- High potassium
- High creatinine
Overview / Summary
Rhabdomyolysis clue হলো crush injury বা muscle damage-এর এমন signal, যেমন muscle pain/swelling/weakness, dark urine, urine কমে যাওয়া, CK >1000 IU/L, potassium/creatinine বাড়া। Crush injury patient-এ এই clue থাকলে kidney failure ও arrhythmia prevent করার জন্য urgent hospital management দরকার।
