25
What are the phases of burn injury
1. Emergent or Resuscitative Phase 2. Acute or Intermediate Phase 3. Rehabilitation Phase
26
What is the time period for emergent or resuscitative phase of burn injury
onset of injury to completion of fluid resuscitation (since they are risk for hypovolemia)
27
What is the time period for the acute or intermediate phase of a burn injury
from the beginning of diuresis until wound closure
28
What is the time period for the rehabilitation phase of burn injury
from wound closure to return to optimal physical and psychosocial adjustment (think of the psychological and skin graft self concept effects)
29
What on the scene care is done during the emergent or resuscitative phase of a burn injury
prevent injury to rescuer - gotta help yourself before helping others stop the injury: extinguish flames, cool the burn, irrigate chemical burns ABCs: Establish airway breathing and circulation Start O2 and large bore IV fluids Remove restrictive objects (since people swell with burns) and cover the wound Do assessment surveying all body systems and obtain a hx of the incident and pertinent patient
30
What is important to keep in mind with on the scene burn care if the patient may have fallen or had an electrical injury
to treat them as potential cervical spine injuries/patients
31
What care is done during the emergent or resuscitative phase
pt moved to ED fluid resuscitation begins foley catheter inserted NG tube if indicated for suction pt stabilized and condition continually monitored ECG address pain psychosocial considerations and emotional support give to patient and family
32
Patients with burns exceeding what percentage should have an NG tube inserted and placed to suction
20-25%
33
Patients with electrical burns need to have a ____
ECG
34
When addressing pain for an emergent or resuscitative phase burn, only give meds how?
Via IV Administration
35
Acute or Intermediate Phase of burn injuries occurs ___ to ___ hours after injury
48-72 hours after injury
36
Management in the Acute or Intermediate Phase
continue assessment, maintain resp and circ support, fluid and electrolyte balance, GI and renal function Prevent infection Burn wound care, pain management, modulation of hypermetabolic response Early positioning and mobility Watch for hypovolemia
37
____ is begun at all stages of burn injuries technically
rehabilitation
38
What is the focus and management like in the Rehabilitation Phase of Burn Injuries
Focus is on wound healing, psychological support, self image, lifestyle, and restoring maximal functional abilities Patient may need reconstructive surgery to improve fxn and appearance Vocational, psychological counseling, and support groups may assist the patient Include family as indicated
39
What nursing interventions of the burn patient are done in the acute phase
Restoring fluid balance preventing infection modulating hypermetabolism promoting skin integrity relieving pain and discomfort promoting mobility strengthening coping strategies
40
What nursing interventions are done for the burn patient in the intermediate and rehabilitation phases
strengthening coping strategies support patient and family processes monitoring and managing complications
41
T/F: Breathing must be assessed and a patent airway established immediately during the initial minutes of emergency burn care?
True - think of the ABCs
42
Why is fluid resuscitation so important in burn patients
Fluid shifts occur from intravascular to interstitial d/t the inflammatory response move from cells to other body parts and fluid loss occurs causing general dehydration s/s intracellularly fluid also evaporates from a burn injury
43
Management of Fluids / Fluid Replacement is required in adults with burns greater than ___%; in children with burns greater than ___%; and any burn in ages less than ___ or greater than ___
adults - 20% children 10% in any burn less than 2 yo or greater than 60 yo
44
Fluid replacement goals for adult burns include a BP of what? A pulse of what? and urinary output of what?
BP >100 systolic Pulse <110 UO >30 cc/hr adults
45
What is usually the basis for the formula for fluid replacement with burns
TBSA (total body surface area)
46
How fast are fluids usually instilled for burn fluid resuscitation
50% of the fluids are given in the first 8 hours - since most fluid lost, shifts, and evaporation occur then the next 50% of fluids are given in the 16 hours following that (25% given in first half of the 16 and 25% given in second half)
47
What may be used for fluid resuscitation of a burn victim
Usually its an isotonic solution like lactated ringers solution May replace PRBCs with blood loss so blood transfusion potential exists
48
Other Criteria for Adequate Fluid Resuscitation
appropriate sensorium appropriate BP and pulse relief of nausea and ileus after 24 hours
49
Signs and Symptoms of Fluid Loss/Burn Shock
decreased BP decreased LOC decreased UO Increased pulse Increased Hct edema at burn site Na deficit K excess (cell destruction) Metabolic acidosis
50
Management of Shock - Fluid Resuscitation
maintain a BP of greater than 100 sys and UO of 30-50 mL/hr Maintain serum sodium at near normal levels Pick your fluid based on several formulas like consensus, evans, brooke army, parkland baxter, hypertonic saline formulas
51
What are some s/s of the fluid and electrolyte shifts occurring in the burn emergent phase
generalized dehydration reduced blood volume and hemoconcentration decreased UO trauma causes release of K into extracellular fluid - Hyperkalemia sodium trapping in edema fluid and shifts into cells as K is released - Hyponatremia Metabolic Acidosis
52
S/S of fluid and electrolyte shifts in the acute/intermediate phase
fluid re enters the vascular space from the interstitial space hemodilution increased UO Na loss with diuresis and due to dilution as fluid enters vascular space - Hyponatremia still K shifts from extracellular fluid into cells - Potential Hypokalemia Metabolic Acidosis
53
Formulas are only a guide for burn care fluid resuscitation. How often must the patient's response to fluid therapy (HR, BP, UO) be evaluated?
At least hourly
54
What is involved in burn wound care
1. Wound cleaning with hydrotherapy, antibacterial products, and wash solutions 2. Use of numerous topical agents - very common - antibacterial creams for example 3. Wound debridement: autolytic, mechanical, surgical 4. Wound dressing, dressing changes, and skin grafting / monitoring
55
What is considered one of the most severe forms of acute pain
Burn pain
56
Pain for burn injuries occurs when else other than just with the burn itself
pain accompanies care and treatments such as wound cleaning and dressing changes
57
Types of Burn Pain
Background or Resting Pain Procedural Pain Breakthrough Pain
58
One of the hardest areas of burn wound care is
Managing the pain - it is hard to have under control
59
Methods of Pain management in burn victims
Analgesics - IV during emergent/acute phases, Morphine, Fentanyl, Other Drugs Role of Anxiety in Pain - Relieve Anxiety Effect of Sleep Deprivation on Pain - Promote sleep + environment Nonpharmacologic Measures
60
What is important to know about nutrition and burns
Burn injuries produce profound metabolic abnormalities Patients with burns have great nutritional needs related to stress response, hypometabolism, and for wound healing
61
The goal of nutritional support for burn patients is what
to promote a state of nitrogen balance and match nutrient utilization
62
Nutritional support of burn patients is based on what
patient pre burn status AND % of TBSA burned
63
What is the preferred route of nutritional support for burn patients?
Enteral route; A jejunal feeding is often used to maintain nutritional status with a lower risk of aspiration in a patient with poor appetite, weakness, or other problems
64
What is some important aspects of home care management of the burn patient once they return home
mental health skin and wound care exercise and activity nutrition pain management sexual issues pulmonary care psychological support of patient and family patient and family education restoration of function thermoregulation and clothing (VERY HOLISTIC APPROACH WHEN CARING IN THE HOME)
65
