Here is a complete, detailed write-up on Blood and Blood Products in Emergency Medicine - fully suitable for your log book.

Blood and Blood Products in Emergency Medicine


1. INTRODUCTION

Blood is a connective tissue composed of plasma and cellular components. In emergency medicine, blood and blood products are used to:
  • Restore oxygen-carrying capacity (in hemorrhage/anemia)
  • Correct coagulation defects (in bleeding disorders)
  • Replace volume (in shock)
  • Treat thrombocytopenia (in massive bleeding)
Modern transfusion practice uses component therapy - giving the specific component the patient needs, rather than whole blood.

2. COMPONENTS OF BLOOD

ComponentNormal Value
Red Blood Cells (RBCs)4.5-5.5 million/µL
White Blood Cells (WBCs)4,000-11,000/µL
Platelets1,50,000-4,00,000/µL
Plasma55% of blood volume
Total Blood Volume~5 litres (adult)

3. BLOOD PRODUCTS AND THEIR DETAILS


A. WHOLE BLOOD

FeatureDetails

ContentsRBCs + WBCs + Platelets + Plasma + Clotting factors
Storage2-6°C, shelf life 35 days
IndicationMassive haemorrhage, trauma resuscitation, exchange transfusion in neonates
Blood GroupMust be ABO and Rh compatible
Emergency Use: Military studies showed whole blood improves mortality in massive trauma. Some Level I trauma centres now use Low-Titre Group O Whole Blood (LTOWB) as universal emergency product.

B. PACKED RED BLOOD CELLS (PRBC)

FeatureDetails
Volume250-350 mL per unit
Haematocrit55-80%
Storage2-6°C, shelf life 35-42 days
Raises Hb by~1 g/dL per unit (adult)

Emergency Transfusion Triggers (Guidelines):
  • Hb < 7 g/dL - stable ICU patients
  • Hb < 8 g/dL - cardiovascular disease or active bleeding
  • Hb 7-9 g/dL - severe trauma patients
In Emergency (No Time for Cross-match):
  • Use Group O Negative (O-) - universal donor RBCs
  • O- is preferred for females of childbearing age and pregnant women
  • O+ can be used for adult males in life-threatening emergencies

C. PLATELETS

FeatureDetails
Volume50-70 mL (single donor) / 300 mL (apheresis)
Storage20-24°C with agitation, shelf life 5-7 days
Raises Platelet count~30,000-50,000/µL per pool
IndicationPlatelet count <10,000/µL (prophylactic), <50,000/µL with active bleeding or before surgery, <100,000/µL in massive transfusion
Emergency Use:
  • Active haemorrhage with thrombocytopenia
  • Massive transfusion protocol (MTP)
  • Post-cardiopulmonary bypass bleeding
  • Dengue haemorrhagic fever with severe thrombocytopenia
Note: ABO compatible preferred but not mandatory. Rh-negative patients receiving Rh-positive platelets should receive anti-D immunoglobulin.

D. FRESH FROZEN PLASMA (FFP)

FeatureDetails

ContentsAll clotting factors, fibrinogen, albumin, immunoglobulins
Storage-18°C or below, shelf life 12 months; once thawed use within 24 hours
Dose10-20 mL/kg to achieve >30% factor activity
IndicationCoagulopathy, liver disease with bleeding, DIC, warfarin reversal (when PCC not available), TTP, massive transfusion
Emergency Indications for FFP:
  • Massive transfusion (give with PRBCs and platelets in 1:1:1 ratio)
  • DIC (Disseminated Intravascular Coagulation)
  • Liver failure with bleeding
  • Reversal of warfarin when Prothrombin Complex Concentrate (PCC) is not available
  • Factor deficiencies (V, XI) where concentrates are unavailable
  • Coagulopathy: PT/INR > 1.5 times control
Contraindication: Do NOT use FFP prophylactically without clinical evidence of bleeding.

E. CRYOPRECIPITATE

FeatureDetails
Volume10-20 mL per unit
ContentsFactor VIII, Factor XIII, von Willebrand factor (vWF), Fibrinogen, Fibronectin
Storage-18°C, shelf life 12 months
Dose1 unit per 5-10 kg body weight; target fibrinogen >1.5 g/L
IndicationHaemophilia A (if Factor VIII concentrate not available), von Willebrand disease, hypofibrinogenaemia, DIC, massive transfusion
Emergency Use: Used when fibrinogen falls below critical level (<1.5 g/L) in massive haemorrhage or DIC.

F. FIBRINOGEN CONCENTRATE

  • More concentrated than cryoprecipitate
  • Used in severe hypofibrinogenaemia (fibrinogen <1.5 g/L)
  • Faster to prepare than cryoprecipitate in emergency
  • Dose: 2-4 grams IV

G. PROTHROMBIN COMPLEX CONCENTRATE (PCC)

  • Contains Factors II, VII, IX, X (and Proteins C & S)
  • Emergency use: Rapid reversal of warfarin/Vitamin K antagonists, life-threatening bleeding
  • Acts faster than FFP
  • Dose: Based on INR and body weight
  • Does NOT require thawing - ready to use immediately

H. ALBUMIN

FeatureDetails
Type5% (iso-oncotic) and 25% (hyper-oncotic)
IndicationHypoalbuminaemia, liver cirrhosis (SBP, large volume paracentesis), nephrotic syndrome, burns
Emergency UseVolume replacement in septic shock, burns >30% BSA

I. ANTI-D IMMUNOGLOBULIN

  • Given to Rh-negative mothers or patients who receive Rh-positive blood products
  • Prevents anti-D alloimmunization
  • Important in emergency transfusion of Rh- females

4. COMPATIBILITY TESTING IN EMERGENCY

TestTime RequiredNotes
Full Cross-match (type & screen)45-60 minutesStandard, safest
Type-specific but uncross-matched10-15 minutesAcceptable in emergency
Group O Negative (uncross-matched)ImmediateLife-threatening emergency only
Electronic cross-match5-10 minutesIf no antibodies on record
Key Rule:
  • O Negative RBCs = Universal donor RBCs (emergency use)
  • AB Positive Plasma = Universal donor plasma (no anti-A or anti-B antibodies)

5. MASSIVE TRANSFUSION PROTOCOL (MTP)

Definition: Transfusion of >10 units PRBCs in 24 hours OR >4 units in 1 hour

Trigger Criteria for MTP:

  • Systolic BP < 90 mmHg
  • Heart Rate > 120 bpm
  • Mechanism suggesting major haemorrhage (RTA, stab, gunshot, ruptured AAA)
  • Haemoglobin < 7 g/dL with ongoing bleeding

MTP Ratio - PROPPR Trial Evidence:

PRBCs : FFP : Platelets = 1 : 1 : 1
This ratio:
  • Prevents dilutional coagulopathy
  • Reduces crystalloid use
  • Reduces acidosis
  • Improves 24-hour and 30-day survival

MTP Steps in Emergency:

  1. Activate MTP - inform blood bank immediately
  2. Start with 6 units PRBCs + 6 units FFP + 1 apheresis platelet
  3. Check labs every 30-60 minutes (Hb, PT, aPTT, platelet count, fibrinogen)
  4. Add cryoprecipitate if fibrinogen < 1.5 g/L
  5. Consider Tranexamic Acid (TXA)
  6. Aim for: Hb > 7, Platelets > 50,000, Fibrinogen > 1.5 g/L, INR < 1.5

6. TRANEXAMIC ACID (TXA) - Emergency Adjunct

  • Drug class: Antifibrinolytic
  • Mechanism: Inhibits plasminogen activation, prevents clot breakdown
  • Dose: 1 gram IV over 10 minutes, then 1 gram IV over 8 hours
  • Time limit: Must be given within 3 hours of injury (CRASH-2 trial)
  • Indications: Trauma with haemorrhage, post-partum haemorrhage, TBI with haemorrhage
  • Contraindication: Do NOT give after 3 hours - may increase mortality

7. DAMAGE CONTROL RESUSCITATION (DCR) - Emergency Principle

Core principles:
  1. Direct pressure / tourniquet to control external bleeding
  2. Permissive hypotension - target SBP 70-90 mmHg until surgical haemorrhage control (avoids "popping the clot")
  3. Minimal crystalloid - avoid normal saline (causes hyperchloraemic acidosis)
  4. Early blood product transfusion in 1:1:1 ratio
  5. Early operative control - transfer to OT or angiography for definitive haemostasis
  6. TXA within 3 hours
  7. Warm blood products - prevent hypothermia (use blood warmers)
  8. Correct the Lethal Triad:
    • Hypothermia (<35°C)
    • Acidosis (pH <7.35)
    • Coagulopathy

8. TRANSFUSION REACTIONS

ReactionTimingFeaturesManagement
Acute Haemolytic (AHTR)During/immediately afterFever, chills, back pain, hypotension, haemoglobinuria, renal failureSTOP transfusion immediately; IV fluids; monitor urine output

Here is the complete, detailed write-up on ABG - Arterial Blood Gas, one by one, with all 4 results explained fully for your log book.

ARTERIAL BLOOD GAS (ABG) - Complete Details


WHAT IS ABG?

Arterial Blood Gas (ABG) is a blood test taken from an artery (usually radial artery at wrist) that measures:
  • How well the lungs are working (oxygenation and ventilation)
  • Acid-base balance of the body

NORMAL ABG VALUES (Must Memorize)

ParameterFull FormNormal Value
pHPotential of Hydrogen7.35 - 7.45
PaCO2Partial pressure of CO2 in arterial blood35 - 45 mmHg
PaO2Partial pressure of O2 in arterial blood80 - 100 mmHg
HCO3-Bicarbonate (Metabolic indicator)22 - 26 mEq/L
SaO2Arterial Oxygen Saturation95 - 100%
Base Excess (BE)Buffer base deviation-2 to +2 mEq/L

Quick Memory Trick:

  • pH = Lungs + Kidneys balance
  • PaCO2 = Lungs control this (respiratory indicator)
  • HCO3- = Kidneys control this (metabolic indicator)

HOW TO INTERPRET ABG - STEP BY STEP

Step 1: Look at pH - Is it acidosis or alkalosis?
  • pH < 7.35 = Acidosis
  • pH > 7.45 = Alkalosis
Step 2: Look at PaCO2 and HCO3 - Is it respiratory or metabolic?
  • PaCO2 > 45 = Respiratory cause
  • HCO3 < 22 = Metabolic cause
Step 3: Check compensation - Is the other system trying to correct it?
Step 4: Calculate Anion Gap (for metabolic acidosis)
  • Anion Gap = Na+ - (Cl- + HCO3-)
  • Normal = 8-12 mEq/L

ABG INTERPRETATION FLOWCHART

Stepwise ABG Interpretation Flowchart

THE 4 RESULTS OF ABG - ONE BY ONE


RESULT 1: RESPIRATORY ACIDOSIS

Definition

pH is low (acidosis) caused by CO2 retention - the lungs are not removing enough CO2.

ABG Values:

ParameterValue
pH< 7.35 (LOW)
PaCO2> 45 mmHg (HIGH)
HCO3-Normal (acute) / High >26 (chronic - compensated)

Simple Rule:

pH ↓ + PaCO2 ↑ = Respiratory Acidosis

Mechanism:

  • Hypoventilation → CO2 builds up in blood
  • CO2 + H2O → H2CO3 (Carbonic acid) → pH falls
  • Lungs are the problem

Causes (Emergency Medicine):

CauseExamples
Airway obstructionChoking, foreign body, laryngospasm
CNS depressionOpioid overdose, sedative overdose, head injury
Neuromuscular diseaseMyasthenia gravis, Guillain-Barre syndrome
Chest wall injuryFlail chest, multiple rib fractures
Lung diseaseCOPD exacerbation, severe asthma, pneumothorax
Drowning / near-drowning
Cardiac arrest

Compensation:

  • Kidneys compensate (slow - takes 3-5 days)
  • Kidneys retain HCO3- → HCO3 rises to correct pH
  • Acute: HCO3 rises 1 mEq/L per 10 mmHg rise in PaCO2
  • Chronic: HCO3 rises 3.5 mEq/L per 10 mmHg rise in PaCO2

Clinical Features:

  • Dyspnoea, confusion
  • CO2 narcosis - drowsiness, headache
  • Flushed, warm skin (vasodilation due to CO2)
  • Cyanosis (in severe cases)
  • Papilloedema (raised ICP from CO2-induced cerebral vasodilation)

Emergency Management:

  1. Open airway - head tilt, chin lift, jaw thrust
  2. Bag-Valve-Mask (BVM) ventilation
  3. Intubation if not breathing
  4. Treat cause (naloxone for opioid OD, bronchodilators for asthma)
  5. Non-invasive ventilation (NIV/BiPAP) for COPD
  6. Do NOT give NaHCO3 (controversial, not effective in respiratory acidosis)

RESULT 2: RESPIRATORY ALKALOSIS

Definition

pH is high (alkalosis) due to excessive CO2 blown off - the lungs are over-ventilating.

ABG Values:

ParameterValue
pH> 7.45 (HIGH)
PaCO2< 35 mmHg (LOW)
HCO3-Normal (acute) / Low <22 (chronic - compensated)

Simple Rule:

pH ↑ + PaCO2 ↓ = Respiratory Alkalosis

Mechanism:

  • Hyperventilation → too much CO2 blown out
  • Less carbonic acid → pH rises
  • Lungs are over-working

Causes (Emergency Medicine):

CauseExamples
Anxiety / Panic attackHyperventilation syndrome
PainAny severe pain causing tachypnoea
Fever / SepsisIncreased respiratory drive
HypoxiaAny condition causing low O2 (pneumonia, PE, altitude)
PregnancyProgesterone stimulates breathing
Pulmonary embolism (PE)Very common emergency cause
CNS causesMeningitis, stroke, head injury
DrugsSalicylate (aspirin) toxicity (early), mechanical over-ventilation
Liver failure / Cirrhosis

Compensation:

  • Kidneys compensate (slow - 2-3 days)
  • Kidneys excrete HCO3- → HCO3 falls
  • Acute: HCO3 falls 2 mEq/L per 10 mmHg fall in PaCO2
  • Chronic: HCO3 falls 5 mEq/L per 10 mmHg fall in PaCO2

Clinical Features:

  • Tingling / numbness of hands, feet, lips (perioral)
  • Carpopedal spasm (Chvostek's / Trousseau's sign in severe cases)
  • Light-headedness, dizziness
  • Palpitations
  • Chest tightness
  • Syncope (fainting)

Emergency Management:

  1. Reassure the patient (if anxiety-related)
  2. Rebreathing into a paper bag (for hyperventilation syndrome - controversial now)
  3. Treat the underlying cause (PE: anticoagulation; fever: antipyretics)
  4. For mechanically ventilated patients: reduce respiratory rate or tidal volume
  5. Pain management if pain is the cause

RESULT 3: METABOLIC ACIDOSIS

Definition

pH is low (acidosis) caused by loss of HCO3- or gain of acid - kidneys/metabolism is the problem.

ABG Values:

ParameterValue
pH< 7.35 (LOW)
HCO3-< 22 mEq/L (LOW)
PaCO2Normal (uncompensated) / Low <35 (compensated - Kussmaul breathing)

Simple Rule:

pH ↓ + HCO3 ↓ = Metabolic Acidosis

Mechanism:

  • Acid accumulates in body OR bicarbonate is lost
  • pH falls
  • Kidneys or metabolism is the problem
  • Lungs try to compensate by blowing off CO2 (deep fast breathing)

ANION GAP - Important Classification:

Anion Gap = Na+ - (Cl- + HCO3-) → Normal = 8-12 mEq/L

High Anion Gap Metabolic Acidosis (HAGMA):

Mnemonic: MUDPILES or KULT
MnemonicCause
MMethanol poisoning
UUraemia (renal failure)
DDiabetic Ketoacidosis (DKA)
PParacetamol / Propylene glycol
IIsoniazid / Iron poisoning
LLactic acidosis (sepsis, cardiac arrest, shock)
EEthylene glycol (antifreeze)
SSalicylate (aspirin) toxicity

Normal Anion Gap Metabolic Acidosis (NAGMA):

Mnemonic: HARDUPS or FUSED
  • Diarrhoea (loss of HCO3)
  • Renal Tubular Acidosis (RTA)
  • Fistulas (pancreatic, small bowel)
  • Addison's disease
  • Dilutional (excess IV normal saline)

Compensation:

  • Lungs compensate (fast - minutes to hours)
  • Hyperventilation to blow off CO2
  • Winter's Formula: Expected PaCO2 = (1.5 × HCO3) + 8 ± 2
  • Classic: Kussmaul breathing - deep, rapid, laboured breathing (seen in DKA)

Clinical Features:

  • Deep rapid breathing (Kussmaul)
  • Fruity breath (DKA)
  • Confusion, drowsiness
  • Hypotension, shock
  • Weakness, fatigue
  • Nausea, vomiting
  • Cardiac arrhythmias (severe)

Emergency Management:

  1. Treat the underlying cause
    • DKA: Insulin + IV fluids + K+ replacement
    • Sepsis/Lactic acidosis: Antibiotics + fluid resuscitation
    • Renal failure: Dialysis
    • Poisoning: Specific antidote
  2. NaHCO3 (Sodium Bicarbonate):
    • Give ONLY when pH < 7.1 or severe symptomatic acidosis
    • Dose: 1-2 mEq/kg IV slow infusion
    • NOT routinely given for DKA
  3. IV fluids (correct hypovolaemia)
  4. Oxygen therapy
  5. Monitor ECG for arrhythmias

RESULT 4: METABOLIC ALKALOSIS

Definition

pH is high (alkalosis) due to gain of HCO3- or loss of acid - kidneys/metabolism is the problem.

ABG Values:

ParameterValue
pH> 7.45 (HIGH)
HCO3-> 26 mEq/L (HIGH)
PaCO2Normal (uncompensated) / High >45 (compensated - hypoventilation)

Simple Rule:

pH ↑ + HCO3 ↑ = Metabolic Alkalosis

Mechanism:

  • Acid is lost from the body OR bicarbonate accumulates
  • pH rises
  • Kidneys/GI tract is the problem
  • Lungs try to compensate by retaining CO2 (slow, shallow breathing)

Causes (Emergency Medicine):

CauseExamples
VomitingLoss of HCl from stomach - most common
NG tube suctionRemoves gastric acid
DiureticsFrusemide, thiazides (lose H+ and Cl-)
HypokalemiaLow K+ → kidneys retain H+ and lose HCO3 less
Excess alkali intakeNaHCO3 overdose, antacid abuse (Milk-alkali syndrome)
CorticosteroidsIncrease aldosterone-like effect
HyperaldosteronismCushing's syndrome, Conn's syndrome
Blood transfusionCitrate in stored blood converts to HCO3

Compensation:

  • Lungs compensate (limited)
  • Hypoventilation to retain CO2
  • Expected PaCO2 = 0.7 × HCO3 + 21 ± 2
  • Limited compensation - body won't let PaO2 drop too much

Classification by Urine Chloride (Cl-):

TypeUrine Cl-CausesTreatment
Saline-Responsive< 20 mEq/LVomiting, NG suction, diureticsIV Normal Saline + KCl
Saline-Resistant> 20 mEq/LHyperaldosteronism, Cushing'sTreat cause; Spironolactone

Clinical Features:

  • Nausea, vomiting
  • Muscle weakness, cramps
  • Tetany (in severe cases - low ionised calcium due to high pH)
  • Confusion, seizures
  • Cardiac arrhythmias (especially with hypokalemia)
  • Slow, shallow breathing (hypoventilation compensation)

Emergency Management:

  1. IV Normal Saline (0.9% NaCl) - first line if volume depleted
  2. Potassium replacement (KCl IV) - essential, correct hypokalaemia
  3. Stop the cause - stop diuretics, stop NG suction if possible
  4. Acetazolamide - used in critically ill, makes kidneys excrete HCO3-
  5. Spironolactone - for hyperaldosteronism
  6. HCl via central line - for severe refractory cases
  7. Dialysis - if in renal failure

EMTC HANDOVER AND REFERRAL SHEET

Emergency Medicine and Trauma Care


PART A: WHAT IS A HANDOVER?

Handover = The process of transferring responsibility and information about a patient from one healthcare provider to another.

Why is Handover Important?

  • Prevents errors in patient care
  • Ensures continuity of treatment
  • Reduces risk of missed information
  • Legally required documentation
  • Protects both patient and staff

When is Handover Done?

  • Shift change (duty handover)
  • Department to department (ED to ICU, ED to OT)
  • Inter-hospital transfer (referral)
  • Pre-hospital to ED (ambulance to emergency team)
  • ED to ward (admission handover)

PAGE 1: SCORPION STING 🦂


DEFINITION

A scorpion sting is envenomation caused by the injection of venom through the stinger on the scorpion's tail. Medically dangerous species include Mesobuthus tamulus (Red Scorpion) - most deadly species found in India, especially Tamil Nadu, Maharashtra, and Andhra Pradesh.

VENOM MECHANISM

  • Scorpion venom contains neurotoxins that keep sodium channels open
  • This causes massive release of catecholamines (adrenaline, noradrenaline)
  • Results in autonomic storm - both sympathetic and parasympathetic overactivation

GRADES OF SCORPION STING (Clinical Grading)

GradeFeatures
Grade ILocal pain and swelling only at sting site
Grade IISystemic symptoms - sweating, vomiting, hypertension OR hypotension, tachycardia
Grade IIISevere - Pulmonary oedema, cardiogenic shock, multi-organ failure

CLINICAL FEATURES

Local:

  • Severe burning pain at sting site
  • Swelling, redness, ecchymosis
  • Paresthesia (tingling/numbness)
  • Tap test positive - tapping on sting site increases pain

Systemic (Autonomic Storm):

Sympathetic OveractivationParasympathetic Overactivation
HypertensionHypotension (late)
TachycardiaBradycardia
Sweating (profuse)Excessive salivation
Restlessness, anxietyLacrimation (watering eyes)
Cold clammy extremitiesVomiting, diarrhoea

Neuromuscular:

  • Muscle twitching, jerking (can look like seizure)
  • Blurred vision, abnormal eye movements
  • Slurred speech
  • Difficulty swallowing secretions

Cardiovascular (Severe):

  • Acute pulmonary oedema (most common cause of death)
  • Myocarditis
  • Cardiogenic shock

Other:

  • Hyperthermia
  • Rhabdomyolysis
  • Acidosis
  • Acute kidney injury (Hemiscorpius species - cytotoxic)

INVESTIGATIONS

TestFinding
ECGTachycardia, arrhythmias, ST changes
Chest X-rayPulmonary oedema
Blood SugarHyperglycaemia
Serum electrolytesHyponatraemia, hypokalaemia
ABGMetabolic acidosis
Cardiac enzymesElevated (myocarditis)
CBC, RFTBaseline

EMERGENCY MANAGEMENT

Step 1 - Stabilise (ABC)

  • Airway: Maintain; intubate if GCS falls
  • Breathing: O2 therapy; mechanical ventilation if pulmonary oedema
  • Circulation: IV access, ECG monitoring, fluid management

Step 2 - Local Care

  • Do NOT incise or suck the sting site
  • Apply cold pack / ice pack to slow venom absorption
  • Pressure dressing around site
  • Keep patient calm and still

Step 3 - Drug Treatment

DrugDoseIndication
Prazosin (alpha blocker)250-500 mcg oral every 3-4 hrsDrug of choice in India for Grade II/III - controls hypertension and reverses pulmonary oedema
Midazolam IV infusion0.1-0.2 mg/kgAgitation, muscle twitching
Atropine IV0.01-0.02 mg/kgBradycardia, excessive secretions
Nifedipine5-10 mg sublingualHypertension + pulmonary oedema
Frusemide IV1-2 mg/kgPulmonary oedema
DobutamineInfusionCardiogenic shock
AnalgesicsParacetamol / TramadolPain relief
AntihistaminesPromethazine IVAllergic component

Step 4 - Antivenom

  • Scorpion Antivenom (Polyvalent, India - Bharat Serums)
  • Given IV diluted in 100 mL NS over 30 min
  • Effective against Mesobuthus tamulus (Indian Red Scorpion)
  • Indicated for Grade II and Grade III envenomation
  • Keep adrenaline ready for anaphylaxis

Step 5 - Tetanus Prophylaxis

  • TT injection if not vaccinated in last 5 years

DISPOSITION

  • Grade I: Observe 4-6 hours, discharge with advice
  • Grade II/III: ICU admission, monitor ECG, BP, SpO2 continuously
  • Symptoms peak at ~5 hours; resolve in 24-48 hours
  • Pain and paresthesia may last weeks

KEY POINT FOR INDIA 🇮🇳

Prazosin is the specific treatment for Indian Red Scorpion (Mesobuthus tamulus) sting. It is NOT available in some countries but is the drug of choice in India. Give early before pulmonary oedema develops.

PAGE 2: DOG BITE WITH RABIES (RIG/Vaccine)


DEFINITION

A dog bite is a wound caused by a dog's teeth. In emergency medicine, the main concern is:
  1. Wound management (infection, tetanus)
  2. Rabies Post-Exposure Prophylaxis (PEP) - the most critical step

RABIES - KEY FACTS

  • Caused by Rabies Lyssavirus - a Rhabdovirus
  • Transmitted via saliva of infected animal through bite, scratch, or mucous membrane contact
  • 100% fatal once clinical symptoms develop
  • Incubation period: 1-3 months (range: 1 week to 1 year)
  • Virus travels via peripheral nerves to the brain (retrograde axonal transport)
  • India accounts for 36% of global rabies deaths (approximately 20,000/year)

WHO CLASSIFICATION OF BITE (Category System)

CategoryType of ContactAction
Category ITouching, feeding the animal; licking on intact skinWash hands - No PEP needed
Category IIMinor scratches/abrasions without bleeding; nibbling of uncovered skinWound wash + Vaccine only
Category IIISingle/multiple transdermal bites or scratches, licks on broken skin; mucous membrane contact; bat biteWound wash + Vaccine + RIG

WOUND MANAGEMENT (First and Most Important Step)

"Immediate wound washing is the single most important first aid measure"

Steps:

  1. Wash wound immediately with soap and water for minimum 15 minutes
  2. Apply 70% alcohol / povidone iodine - viricidal
  3. Do NOT suture the wound immediately (allows virus to escape)
    • If suturing needed (cosmetic/large wound), give RIG first, then suture after 2-4 hours
  4. Do NOT cover tightly - leave slightly open
  5. Debride devitalised tissue if present
  6. Assess wound depth and nerve/tendon involvement

RABIES POST-EXPOSURE PROPHYLAXIS (PEP)

TWO COMPONENTS:

1. RIG - Rabies Immunoglobulin (Passive Immunity - Immediate Protection)

TypeDoseRoute
Human Rabies Immunoglobulin (HRIG)20 IU/kg body weightInfiltrated into wound + remainder IM at distant site
Equine Rabies Immunoglobulin (ERIG)40 IU/kg body weightSame as above (test dose required first)

Key Rules for RIG:

  • Give on Day 0 only (same day as first vaccine)
  • Maximum dose of infiltration INTO wound first; remaining IM
  • If anatomically impossible to inject all into wound, give remainder IM at a site away from vaccine
  • Do NOT give RIG and vaccine in the same syringe or same site
  • RIG gives immediate antibodies for 7-10 days until vaccine kicks in
  • If RIG not given on Day 0, give up to Day 7 (after that, not needed)

2. RABIES VACCINE (Active Immunity - Long-term Protection)

Schedule - ESSEN Protocol (5 Dose - IM):

DayDoseSite
Day 01 vial (1 mL) IMDeltoid (right)
Day 31 vial (1 mL) IMDeltoid (left)
Day 71 vial (1 mL) IMDeltoid
Day 141 vial (1 mL) IMDeltoid
Day 281 vial (1 mL) IMDeltoid

Alternative - Zagreb Protocol (4 Dose - 2-1-1):

DayDose
Day 02 doses (both deltoids simultaneously)
Day 71 dose
Day 211 dose
Note: In India, WHO recommends the Essen 5-dose IM protocol or the Updated 4-dose protocol (Days 0,3,7,14)

Vaccine Types Available in India:

  • PCECV - Purified Chick Embryo Cell Vaccine (Rabipur)
  • PVRV - Purified Vero Cell Vaccine (Verorab, Abhayrab)
  • Give in deltoid muscle (adults) or anterolateral thigh (children)
  • Never give in gluteal region (poor immune response)

TETANUS PROPHYLAXIS (Mandatory for all Dog Bites)

Vaccination HistoryWound TypeAction
Fully vaccinated (<5 years)AnyNothing needed
Fully vaccinated (5-10 years)Clean minorNothing needed
Fully vaccinated (5-10 years)ContaminatedTT booster
Unknown / IncompleteAnyTT + TIG (Tetanus Immunoglobulin)
  • TT dose: 0.5 mL IM (deltoid)
  • TIG dose: 250 IU IM (if unvaccinated)

ANTIBIOTIC PROPHYLAXIS

DrugDoseDuration
Amoxicillin-Clavulanate (first choice)625 mg TDS (adult) oral5-7 days
Doxycycline (if penicillin allergy)100 mg BD5-7 days
IV AntibioticsPiperacillin-TazobactamSevere/deep wounds
  • Bacteria in dog mouth: Pasteurella multocida, Staphylococcus, Capnocytophaga canimorsus

ANIMAL OBSERVATION RULE

SituationAction
Dog is alive and healthyObserve for 10 days
If dog stays healthy for 10 daysAnimal is NOT rabid - can stop PEP
If dog dies or develops signs in 10 daysContinue full PEP course
Dog not available / unknownComplete full PEP course
