A 2.0°C drop in core body temperature
can increase blood loss by _________.
a.
100 ml
c.
400 ml
b.
250 ml
d.
500 ml
Answer:
d
Mild hypothermia reduces platelet function and decreases activation of the
coagulation cascade. Therefore, hypothermia can increase blood loss and
require transfusions during surgery. Shivering post-operatively can cause an
increase in oxygen demand, bleeding times and blood viscosity, and contribute
to a risk for metabolic acidosis, along with hyperventilation and hypoxia.
The hoses of forced-air warming units
can be used without attaching them to a custom
gown or blanket, as long as the patient is closely monitored.
a.
true
b.
false
Answer:
b
Never use the hose of a forced-air warming unit without attaching it to the cus-
tom gown or blanket. That should go without saying, but some facilities remain
oblivious to the practice's very real dangers. "Free hosing" concentrates a higher
temperature and airflow to the patient, which can easily cause a burn. It is
important to always follow manufacturers' recommendations when using any
warming device.
