Burn injuries are among the most severe forms of trauma, often requiring long-term medical, surgical, and nursing management. The complexity of burns lies not only in the immediate destruction of skin tissue but also in the systemic responses they trigger—such as fluid loss, electrolyte imbalance, infection risk, and psychological trauma.
To streamline care, burn management is divided into three distinct phases: the Emergent Phase, the Acute Phase, and the Rehabilitative Phase. Each stage has unique physiological changes, goals of care, and nursing responsibilities that ensure the best possible recovery for patients.
This article provides a detailed breakdown of these burn phases—exploring pathophysiology, vital signs, lab findings, nursing considerations, and treatment approaches—making it a complete guide for medical and nursing students, healthcare professionals, and even first responders.
Emergent Phase of Burn Management
Definition and Timing
The emergent phase is the first stage of burn management, beginning at the time of injury and lasting until capillary permeability is restored, typically within 24–48 hours after the burn.
Pathophysiology
- Burn injuries increase capillary permeability, leading to plasma leakage from the intravascular space into interstitial tissues.
- This shift causes edema formation and a fluid volume deficit (FVD) within the vascular space.
- As fluids leave circulation, albumin and sodium follow, worsening hypovolemia.
Clinical Manifestations
Patients in this stage often show signs of hypovolemic shock, such as:
- Rapid, weak pulse
- Hypotension (low blood pressure)
- Decreased cardiac output
- Oliguria (low urine output) due to reduced kidney perfusion
Vital Signs and Lab Findings
Pulse: Increased (tachycardia)Labs:
- Potassium (K⁺): Increased (from cell destruction)
- Hematocrit (HCT): Increased (due to hemoconcentration)
- White blood cells (WBCs): Elevated (stress/inflammation)
- BUN/Creatinine: Elevated (reduced renal perfusion)
Nursing Considerations
- Airway, Breathing, Circulation (ABCs): Priority to secure airway in facial/neck burns.
- IV Access: Establish large-bore intravenous lines.
- Fluid Replacement: Administer crystalloids (e.g., Lactated Ringer’s) using Parkland Formula.
- Urinary Monitoring: Foley catheter to monitor urine output (goal: >30 mL/hr).
- Edema Management: Elevate extremities to reduce swelling.
Key Goal: Prevent hypovolemic shock and maintain organ perfusion.
Acute Phase of Burn Management
Definition and Timing
The acute phase begins 48–72 hours after the burn, once capillary permeability is stabilized and fluid starts shifting back from the interstitial space to the intravascular space. This phase continues until wound closure is achieved.
Pathophysiology
- Fluid mobilization occurs, leading to diuresis (increased urine production).
- Nutritional demands rise significantly due to tissue repair.
- The risk of infection increases as necrotic tissue provides a medium for bacteria.
Goals of the Acute Phase
Prevent Infection: Systemic antibiotics and sterile wound care.Ensure Proper Nutrition:
- High-calorie, high-protein diet.
- Vitamin C and protein supplementation to promote wound healing.
Wound Care:
- Daily dressing changes.
- Debridement (removal of dead tissue).
- Skin grafting if required.
Nursing Considerations
Renal: Diuresis is expected, monitor urine output via Foley catheter.Gastrointestinal: Due to fluid deficit, reduced perfusion to the stomach may cause complications like:
- Paralytic ileus (intestinal paralysis).
- Curling’s ulcer (stress-induced stomach ulcer).
Key Goal: Support wound healing, prevent infection, and maintain nutrition.
Rehabilitative Phase of Burn Management
Definition and Timing
The rehabilitative phase begins once the burn wound has healed or a skin graft is stable. This phase can last for months to years, depending on burn severity and patient recovery.
Goals of Rehabilitative Phase
- Psychosocial Recovery: Counseling, support groups, and mental health care.
- Activities of Daily Living (ADLs): Regaining independence in self-care.
- Physical Therapy (PT): Strengthening, mobility, and reducing contractures.
- Occupational Therapy (OT): Skill training for hand use, work adaptation.
- Cosmetic Corrections: Reconstructive surgery, scar management, and skin graft revisions.
Nursing and Healthcare Considerations
- Encourage patient and family education on wound care and nutrition.
- Monitor for long-term complications such as hypertrophic scars and keloids.
- Promote emotional healing through community reintegration programs.
Key Goal: Restore maximum physical, functional, and psychological well-being.
Comparative Table: Phases of Burn Management
Phase | Duration | Pathophysiology | Main Goals | Nursing Priorities |
---|---|---|---|---|
Emergent | 0–48 hrs after burn | Capillary leak → edema → FVD | Prevent shock, maintain airway & circulation | Fluid resuscitation, ABCs |
Acute | 48 hrs – wound closure | Capillary stability → diuresis → infection risk | Support healing, nutrition, prevent infection | Pain relief, wound care, GI monitoring |
Rehabilitative | After wound closure | Healing, scar formation, psychosocial needs | Maximize independence, physical & mental recovery | PT, OT, psychosocial support |
Frequently Asked Questions (FAQs)
Q1: Why is fluid resuscitation important in the emergent phase?
Fluid loss in the first 24–48 hours leads to hypovolemic shock. Early IV fluids prevent organ failure and death.
Q2: What is the Parkland Formula for burns?
The Parkland Formula calculates fluid needs:
4 mL × body weight (kg) × %TBSA burned. Half is given in the first 8 hours, and the rest over 16 hours.
Q3: Why are burn patients at risk of Curling’s ulcer?
Decreased perfusion to the stomach lining during the acute phase increases the risk of stress-induced gastric ulcers.
Q4: How do nurses support burn patients emotionally?
Through counseling, education, rehabilitation support, and connecting them with burn survivor groups.
Q5: What is the ultimate goal of the rehabilitative phase?
To restore physical independence, emotional stability, and social integration.
