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.
