58
Q

Smoke Inhalation Care

A

AIRWAY IS PRIORITY

59
Q

Carbon Monoxide Poisoning

A

oxygen displace and carbon monoxide binds to hemoglobin to form carboxyhemoglobin leading to tissue hypoxia

60
Q

Carbon Monoxide Poisoning Care

A

can lead to upper airway obstruction during first 24-48 hrs. immediate intubation if obstruction occurs.

61
Q

General Burn Patho

A

increased capillary permeability allows plasma to seep into tissues causing generalized edema and decrease circulating intravascular blood volume. when this occurs there is a decrease in organ perfusion. heart rate increase. cardiac output decreased. blood pressure drops. at first hyponatremia and hyperkalemia occur. blood is shunted from kidneys causing oliguria. body then reabsorbs fluid and diuresis occurs. GI blood is diminished leading to ileus and GI dysfunction. depressed immune system leading to increased risk of sepsis and infection. can lead to hypovolemic shock and death due to fluids deplacing in tissue and not circulating.

62
Q

Resuscitation/Emergent Phase of Burns

A

begins at the time of injury and ends with restoration of normal capillary permeability. remove patient from source of injury. assess ABCs. conserve body heat. cover burns with sterile or clean cloth. remove jewelry and clothes. insert IV. maintain airway with 100% O2. intubation if needed. assess lungs. ABGs and carboxyhemoglobin levels. duration is 48-72 hrs. includes prehospital and emergency department care. goal is to maintain airway give IVF to prevent hypovolemic shock and preserve vital organs

63
Q

Resuscitative Phase of Burns

A

begins with initiation of fluids and ends when capillary integrity returns to normal levels and fluid shifts have decreased. fluid given is based on weight and extent of burn. (calculate from time of injury not from time of hospital arrival). goal is to prevent shock by maintaining circulating volume and organ perfusion

64
Q

Acute Phase of Burns

A

begins when pt is hemodynamically stable capillary permeability is restored and diuresis begins. 48-72 hours after time of injury. focus on infection control wound care wound closure nutrition pain management and PT. emphasis on restorative therapy. phase continues till wound closes.

65
Q

Rehab Phase of Burns

A

extends beyond hospitalization. goal is that pt gains independence and function.

66
Q

Urine Output (30-50ml/hr)

68
Q

Care for Burn Patients

A

airway. O2. IV and IVF. assess lungs. ABGs and carboxyhemoglobin. HOB 30 degrees with facial burns. monitor for pulmonary edema and fluid overload. EKG monitoring. assess for infection. protective isolation. strict hand washing. sterile sheets and linen. clip body hair around wound. daily weight. expect 15-20 lb weight gain in 1st 72 hrs. monitor pH and gastric output for stress ulcer. antacids and antiulcer meds. bowel sounds for ileus and check abdominal distention. check stools for blood. cap refill and pulses. keep room warm. special mattress. pain management. NO IM OR SUBQ MEDS DUE TO FLUID SHIFT. IV MEDS ONLY!! increase to 5000+ calories.

Q

Burn Products

A

SILVER SULFADIAZINE: broad spectrum. prevent sepsis. does not cause acidosis. 1/16 film and keep covered at all times. causes rash itching blue green gray skin discoloration leukopenia and nephritis. check CBC WBC and report leukopenia to MD
MAFENIDE ACETATE: water soluble cream. reduce bacteria. check ABGs and electrolytes. causes local pain and rash. adverse effect is bone marrow depression, anemia, and metabolic acidosis (watcher for hyperventilation). keep covered at all times. report to MD if pt hyperventilates, acidosis develops

87
Q
