The time when the injury happens not time of arrival at ER
What are some circumstancs that may require higher volumes of fluid for fluids resuscitation in a burn patient?
- Presence of inhalation injury
- Electrical injurues
- Associated trauma
- Alcohol & drug dependence
What guage IV is needed for fluid resuscitation in burn patients?

What needs to be in place on a burn patient during fluid resuscitation to closly monitor I & O?
Foley catheter
Priority Nursing interventions in the EMERGENT phase of burn injuries
- Place pt on 100% humidified o2
- Trend ABG values and carboxyhemoglobin levels.
- Elevate the head of the bed to allow for better oxygenation.
- Maintain emergency airway (intubation and tracheostomy) trays at the bedside.
- Assist with intubation as necessary.
- Ensure securement of the endotracheal tube if the patient is intubated.
- Monitor mechanically ventilated patients closely for signs of respiratory compromise.
- Place two large-bore IV catheters and begin fluid resuscitation with lactated Ringer’s.
- Roughly estimate the %TBSA burned and patient weight in kilograms.
- Cover wounds with a clean, dry sheet.
- Institute warming measures in the form of blankets or other external heat sources.
To minimize evaporation heat loss and prevent hypothermia what can be done?
Typically what phase is this?
Institute warming measures in the form of blankets or other external heat sources.
Emergent phase
Burn pt’s that require intubation need to be closly monitored. Why?
Close monitoring of mechanically ventilated patients allows for early detection of respiratory distress. If the tube is dislodged, it may be impossible to reinsert due to the edema. In addition, the securement device will require adjustment (e.g., twill) as the edema continues to worsen/decrease.
What could happen if intubation is delayed when needed?
Edema and inflammation may make it impossible to untubate
A burn pt required intibation, what should the nurse make sure stays at bedside and why?
a tracheostomy tray should be maintained at the bedside in the event of an unplanned extubation.
Why is it important to monitor ABG trends and carboxyhemoglobin levels?
Increasing PaCO2 and decreasing PaO2 and oxygen saturation may indicate the need for intubation. As carboxyhemoglobin levels lower, weaning of oxygen support (FiO2) to a minimal level to sustain oxygenation is indicated
What needs to be done ASAP during treamtent of a pt in the emergent phase of a burn injury? Why?
Place patient on 100% humidified oxygen or assist with intubation if necessary. Immediate intervention is necessary for respiratory distress and to provide humidified oxygen and assist in the clearing of carbon monoxide.
Nursing assessments for patients in the emergent phase of a burn injury
- Breath sounds, respiratory rate, and indicators of inhalation injury
- Oxygen saturation, ABGs, and carboxyhemoglobin levels
- Face and neck for burns, singed nasal and/or facial hair, and singed eyebrows/eyelashes
- Upper airway
- Changes in voice, hoarseness, and swallowing difficulty
- Vital signs
- Urine output
- Anxiety
- Burn wound size and depth
What is the optimal urine output for a burn patient that indicates adequate fluid resuscitation
0.5 mL/kg/hr
or
If myoglobin present: 1 mL/kg/hr
Expected vital signs in the emergent phase of burn wound injuries
- Low BP
- High HR
- Low temp
Indications of inhalation injury
- Hypoxemia
- Wheezing, Crowing, Rhonchi, & Stridor
- Change in voice or hoarsness
- Tachypnea, retractions, and nasal flaring
- Singed nasal hairs, eyebrows and eyelashes
- Brassy cough
- Drooling and/or dysphagia
- Anxiety and/or agitation (r/t hypoxia)
Why are inhalation injuries hard to be caught in pts?
They rarely exhibit S/S of resiratory distress
CHXR are usually normal
How long after a burn injury should a patient be monitored for inhalation injuries?
24 hr
How can inhalation injuries be definitively dx?
Fiberoptic Bronchoscopy
If a pt dos not require intubation for an inhalation injury what needs to be done? And for how long?
They need to be put on 100% humidified oxygen until carboxyhemoglobin levels are mantained below 10%
Signs that fluid resuscitation is adequate for a patient
- Urine output: 0.5 mL/kg/hr or 1 mL/kg/hr if myoglobin present
- Systolic blood pressure: Greater than 100 mm Hg
- Heart rate:Less than 120 bpm
- Central venous pressure (CVP)5–10 mm Hg
- Pulmonary: Lungs sound clear, blood pH within normal range (7.35–7.45)
- Gastrointestinal: Abdomen soft, non-tender; no nausea, vomiting, or ileus; bladder pressure less than 10 mm Hg
- Level of consciousness: Clear; alert; and oriented to person, place, and time
What is the combination of distributive and hypovolemic shock. Occurs from massive fluid shift due to increased capillary permeability (first 8-36 hours)
Burn Shock
How is burn shock treated?
Fuid resuscitation
If a patient is suffering from burn shock and does not recieve fluid resuscitation/adequate fluid resuscitation what can happen?
- Hypotension
- Tachycardia
- Decreased urine output
- Multi-organ failure

What time fram after a burn injury is a patient at risk for burn shock?
8-24 hrs
What time frame does fluid remobilization take place in a patient with a burn injury?
24-48 hrs
What does this describe?
- Capillary leak stops
- Edema fluid shifts from the interstitial spaces into the vascular space
- Blood volume increases leading to increased renal blood flow and diuresis
- Body weight returns to normal
