burn inhalation injury diagnosis
acute burn patient initial diagnostic tests carboxyhemoglobin ABG electrolytes bronchoscopy guideline
“Mixed partial- and full-thickness burns, %TBSA to be calculated; complicated by hypothermia, hypovolemia/burn shock, hyponatremia, and dyspnea. Evaluate urgently for inhalation injury and carbon monoxide poisoning with ABG/co-oximetry, carboxyhemoglobin, CXR, ECG, and bronchoscopy if indicated.”
I meant laboratory investigations.
burn injuries AND laboratory biomarkers
burn injury initial laboratory investigations CBC electrolytes renal function ABG carboxyhemoglobin CK
| Investigation | Why it is done |
|---|---|
| Complete blood count (CBC) | Hemoglobin/hematocrit for hemoconcentration or bleeding; WBC for baseline inflammation/infection; platelet count. |
| Serum electrolytes: Na⁺, K⁺, Cl⁻, HCO₃⁻ | Detect and monitor hyponatremia, potassium abnormalities, and metabolic acidosis. |
| Renal function tests: urea/BUN, serum creatinine | Detect dehydration, hypoperfusion, and acute kidney injury. |
| Blood glucose | Burns cause stress hyperglycemia; hypoglycemia must also be excluded. |
| Arterial blood gas (ABG) | Measures pH, PaO₂, PaCO₂, bicarbonate, and acid-base status in dyspnea/shock. |
| Serum lactate | Raised lactate may indicate poor tissue perfusion, burn shock, or sepsis. |
| Co-oximetry: carboxyhemoglobin (COHb) | Essential if fire/smoke or enclosed-space exposure is possible. Detects carbon monoxide poisoning. |
| Methemoglobin level | If chemical exposure or a burn-related toxic inhalation is suspected. |
| Calcium, magnesium, phosphate | Important in major burns and during fluid resuscitation; abnormalities can affect the heart and muscles. |
| Creatine kinase (CK) | Needed particularly in electrical burns, crush injury, or dark urine to detect muscle damage/rhabdomyolysis. |
| Urinalysis | Checks concentration, blood, protein, and glucose; “blood” with few/no red cells suggests myoglobin. |
| Urine myoglobin | If electrical injury, crush injury, or suspected rhabdomyolysis. |
| Coagulation profile: PT/INR, aPTT, fibrinogen | Assesses coagulopathy, especially in large burns, hypothermia, shock, or before surgery. |
| Blood group, Rh type, and crossmatch | Preparedness for excision, grafting, or transfusion if required. |
| Liver-function tests and serum albumin | Baseline organ function, nutritional status, and protein loss/capillary leak assessment. |
| Blood cultures | Only when sepsis is suspected: fever/hypothermia, hypotension, worsening wounds, high lactate, or organ dysfunction. |
| Wound culture | Only if clinical burn-wound infection is suspected. A fresh burn does not routinely need a wound swab. |
| CRP and/or procalcitonin | Can support infection/sepsis monitoring, but results must be interpreted carefully because burns themselves cause inflammation. |
Give me the investigation charts with investigation, patient value, normal value, remarks. For a care plan.
adult laboratory reference ranges sodium potassium creatinine arterial pH lactate carboxyhemoglobin
| Investigation | Patient value* | Normal value (adult) | Remarks |
|---|---|---|---|
| Hemoglobin (Hb) | 17.2 g/dL | Male: 13.5-17.5 g/dL; Female: 12.0-16.0 g/dL | Mildly raised, likely hemoconcentration due to dehydration/fluid loss. |
| Total WBC count | 16,500 cells/mm³ | 4,000-11,000 cells/mm³ | Leukocytosis may occur from stress and inflammation after burns. Monitor for infection if persistent/rising. |
| Platelet count | 280,000/mm³ | 150,000-450,000/mm³ | Within normal range. Monitor serially in major burns. |
| Serum sodium (Na⁺) | 128 mmol/L | 135-145 mmol/L | Hyponatremia. Requires serial monitoring and careful correction according to fluid status and symptoms. |
| Serum potassium (K⁺) | 4.8 mmol/L | 3.5-5.0 mmol/L | Normal-high. Serial monitoring is required because burns, acidosis, renal injury, and treatment can alter potassium. |
| Serum chloride (Cl⁻) | 96 mmol/L | 98-106 mmol/L | Mildly low, may accompany hyponatremia or fluid/electrolyte loss. |
| Serum bicarbonate (HCO₃⁻) | 18 mmol/L | 22-28 mmol/L | Low. Suggests metabolic acidosis, which may occur in burn shock/hypoperfusion. |
| Blood urea nitrogen (BUN) | 32 mg/dL | 7-20 mg/dL | Raised, consistent with dehydration and reduced renal perfusion. |
| Serum creatinine | 1.5 mg/dL | 0.6-1.3 mg/dL | Mild elevation. Possible acute kidney injury or pre-renal dehydration. Monitor urine output and repeat renal function tests. |
| Random blood glucose | 168 mg/dL | Usually 70-140 mg/dL | Stress hyperglycemia may occur following major burns. Monitor regularly. |
| Serum calcium, total | 8.1 mg/dL | 8.5-10.5 mg/dL | Mildly low. Check albumin/ionized calcium and monitor, especially if large-volume resuscitation is given. |
| Serum magnesium | 1.6 mg/dL | 1.7-2.2 mg/dL | Mild hypomagnesemia. Can contribute to weakness or arrhythmia. |
| Serum phosphate | 2.3 mg/dL | 2.5-4.5 mg/dL | Mildly low. Monitor and correct according to local protocol. |
| Serum lactate | 3.8 mmol/L | 0.5-2.0 mmol/L | Raised. May indicate tissue hypoperfusion/burn shock. Repeat to assess response to resuscitation. |
| ABG pH | 7.30 | 7.35-7.45 | Acidemia. |
| ABG PaO₂ | 68 mmHg | 80-100 mmHg on room air | Low oxygen level, consistent with dyspnea. Assess urgently for inhalation injury or lung complications. |
| ABG PaCO₂ | 32 mmHg | 35-45 mmHg | Low, possibly compensatory hyperventilation. |
| ABG HCO₃⁻ | 16 mmol/L | 22-26 mmol/L | Supports metabolic acidosis. |
| Carboxyhemoglobin (COHb) | 8% | Non-smoker: <2%; smoker: often <5% | If the burn occurred in a fire or enclosed area, this supports carbon monoxide exposure. Requires urgent clinical management. |
| Creatine kinase (CK) | 650 U/L | Approximately 30-200 U/L | Elevated. Check especially if electrical burn, crush injury, deep tissue damage, or dark urine. |
| Urinalysis | Concentrated urine; protein trace | No protein; specific gravity about 1.005-1.030 | Concentrated urine supports dehydration. Check for blood/myoglobin. |
| Urine myoglobin | Negative or pending | Negative | Test particularly if electrical burn, crush injury, high CK, or cola-colored urine. |
| PT/INR | PT 15.2 sec, INR 1.3 | PT about 11-14 sec; INR 0.8-1.2 | Mild prolongation may occur with hypothermia, shock, or evolving coagulopathy. Repeat if extensive burns or surgery is planned. |
| aPTT | 34 sec | About 25-35 sec | Within normal range. |
| Blood group and crossmatch | Sent | Not applicable | Required in major burns because surgical debridement/grafting or transfusion may be needed. |
| Blood culture | Send if clinically indicated | No growth | Obtain if fever/hypothermia, hypotension, raised lactate, wound deterioration, or suspected sepsis. Do not interpret a fresh burn wound culture alone as infection. |
Shortlist them so that I can get only the main investigations
| Investigation | Example patient value* | Normal value | Remarks |
|---|---|---|---|
| Complete blood count (CBC) | Hb 17.2 g/dL; WBC 16,500/mm³ | Hb: 12-17.5 g/dL; WBC: 4,000-11,000/mm³ | Raised Hb suggests dehydration. Raised WBC may result from burn-related stress/inflammation or infection. |

| Renal-function tests | Urea 32 mg/dL; creatinine 1.5 mg/dL | Urea: 7-20 mg/dL; creatinine: 0.6-1.3 mg/dL | Raised values suggest dehydration, reduced kidney perfusion, or early acute kidney injury. |
| ABG with serum lactate | pH 7.30; HCO₃⁻ 18 mmol/L; lactate 3.8 mmol/L | pH: 7.35-7.45; HCO₃⁻: 22-26 mmol/L; lactate: 0.5-2 mmol/L | Metabolic acidosis with raised lactate suggests tissue hypoperfusion/burn shock. Important because the patient has dyspnea. |
| Carboxyhemoglobin level | COHb 8% | Non-smoker: <2% | Do if fire or smoke exposure occurred. An elevated value suggests carbon monoxide poisoning. |
| Urinalysis and urine output | Concentrated urine | Urine output: at least 0.5 mL/kg/hour in adults | Supports dehydration. Monitor hourly urine output to assess adequacy of fluid resuscitation. |
Now give me medication chart
burn wounds AND topical antimicrobial
burn injury initial management analgesia tetanus topical antimicrobial no routine prophylactic antibiotics guideline
| Medication / Fluid | Example dose and route | Frequency | Purpose / remarks |
|---|---|---|---|
| Ringer’s lactate (RL) | IV fluid, rate calculated according to burn-resuscitation protocol and titrated to urine output | Continuous infusion | Corrects intravascular fluid loss and burn shock. Monitor BP, pulse, edema, lung signs, serum sodium, and hourly urine output. |
| Paracetamol (Acetaminophen) | 500-1000 mg PO/IV | Every 6-8 hours as prescribed | For mild to moderate pain and fever. Do not exceed the prescribed daily maximum; use caution in liver disease. |
| Morphine sulfate | IV in small titrated doses as prescribed | PRN for severe pain and before dressing changes | For severe burn pain. Monitor respiratory rate, oxygen saturation, BP, sedation level, nausea, and urine output. Particularly important because the patient has dyspnea. |
| Topical antimicrobial dressing such as silver-containing dressing or bacitracin | Apply locally after wound cleansing, as ordered | With dressing change | Reduces local bacterial colonization and protects the burn wound. Choice depends on burn depth, site, allergy, and burn-team protocol. |
| Tetanus toxoid-containing vaccine | IM, as indicated by immunization history | Single dose when indicated | Prevents tetanus. Tetanus status should be checked in every burn patient. |
| Tetanus immunoglobulin (TIG) | IM, if indicated | Single dose | Given with vaccine when immunization is incomplete/unknown and the wound is considered tetanus-prone, according to local guidelines. |
| Ondansetron | 4 mg PO/IV | PRN, usually every 8-12 hours | For nausea and vomiting caused by opioids, pain, or treatment. Monitor for QT-prolongation risk when relevant. |
| Antibiotic, systemic | Culture-guided drug, dose, and route | Only if prescribed | Not routinely given prophylactically in a fresh burn. Use only for confirmed/suspected wound infection, sepsis, pneumonia, or another documented infection. |
Prepare it like, , medications, dose, route, frequency, action, and nurse's responsibilities.
burn pain management AND analgesia
WHO burn management analgesia tetanus silver sulfadiazine burn care guideline
| Medication | Dose | Route | Frequency | Action | Nurse’s responsibilities |
|---|---|---|---|---|---|
| Ringer’s lactate (RL) | Rate calculated from body weight and %TBSA burn, then titrated to response | IV infusion | Continuous | Restores circulating volume and electrolytes; treats burn shock/dehydration. | Ensure patent IV access; use warmed fluids if hypothermic; monitor pulse, BP, respiratory status, edema, serum electrolytes, and hourly urine output. Report reduced urine output, worsening dyspnea, crackles, or increasing edema. |
| Paracetamol (Acetaminophen) | 500-1,000 mg | PO/IV | Every 6-8 hours as prescribed | Reduces mild to moderate pain and fever by central analgesic action. | Assess pain score and temperature before and after administration; check total daily dose from all products; use caution in liver disease; observe for nausea or rash. |
| Morphine sulfate | 2-5 mg initially, IV slowly and titrated as prescribed | IV | PRN for severe pain / before dressing change | Opioid analgesic that relieves severe burn pain. | Assess pain, BP, pulse, respiratory rate, SpO₂, and level of consciousness before and after dose. Hold and inform clinician if respiratory depression, excessive sedation, or hypotension occurs. Keep naloxone available according to unit policy. |
| Ondansetron | 4 mg | IV/PO | Every 8-12 hours PRN | Antiemetic. Blocks serotonin receptors to reduce nausea and vomiting. | Assess nausea/vomiting, hydration, and bowel function. Monitor ECG/QT risk in patients with electrolyte disturbances, cardiac disease, or concurrent QT-prolonging drugs. |
| Silver sulfadiazine 1% cream if prescribed | Apply a thin layer over cleaned burn wound | Topical | Once or twice daily with dressing change | Broad topical antimicrobial that reduces bacterial colonization in burn wounds. | Check for sulfonamide allergy; cleanse wound using aseptic technique; apply with sterile gloves; avoid eyes and mucous membranes; inspect wound for infection, discoloration, increased discharge, or delayed healing. Monitor CBC if used extensively/prolonged. Some centers prefer newer silver dressings because silver sulfadiazine may delay healing. |
| Tetanus toxoid-containing vaccine | 0.5 mL | IM | Single dose if immunization is incomplete/outdated, as prescribed | Produces active immunity against tetanus. | Check previous immunization record and allergy history; administer as prescribed; document batch number, site, and date; observe for local reaction or anaphylaxis. |
| Tetanus immunoglobulin (TIG) if indicated | As prescribed by local protocol | IM | Single dose | Provides immediate passive protection against tetanus in inadequately immunized patients with tetanus-prone wounds. | Verify indication and immunization history. Administer at a different site from the vaccine; observe for hypersensitivity reaction; document site and dose. |
| Systemic antibiotic only if infection is diagnosed/suspected | Culture-guided and prescribed dose | IV/PO | As prescribed | Treats documented burn-wound infection, sepsis, pneumonia, or another infection. | Obtain cultures before first dose if ordered and if this does not delay treatment; check allergy, renal function, temperature, WBC, wound appearance, and culture results. Do not administer routine prophylactic systemic antibiotics for an uncomplicated fresh burn unless prescribed. |

Patient is conscious but anxious and appears ill. Temperature is low, with dry mucous membranes and clinical signs of dehydration. Tachycardia, tachypnea, and possible hypotension may be present. Dyspnea is noted; examine for facial burns, soot around mouth/nose, singed nasal hairs, hoarseness, wheeze, stridor, and reduced air entry. Mixed partial- and full-thickness burns are present, with blisters, peeling skin, and black dry/leathery areas. Local edema is present. Assess and document %TBSA, burn depth, wound location, pain, sensation, peripheral pulses, capillary refill, and limb movement. Hyponatremia and signs of burn shock require close monitoring.
