sees the machine and see the bp
suddenly drops to 40. What will be best
immediate management -

b) Increase level of anesthesia
c) Ask the surgeon to stop the surgery
d) Give adrenaline
Correct Answer - D
Answer: D. Give adrenaline
Adrenaline should be given to raise the blood pressure.
Epinephrine, also known as adrenalin or adrenaline, is
a hormone, neurotransmitter, and medication. Epinephrine is
normally produced by both the adrenal glands and
certain neurons.
It plays an important role in the fight-or-flight response by
increasing blood flow to muscles, output of the heart, pupil
dilation, and blood sugar. It does this by binding
to alpha and beta receptors.
Physiologic responses to epinephrine by organ
Organ Effects
Heart Increases heart rate; contractility; conduction across
AV node
Lungs Increases respiratory rate; bronchodilation
Systemic Vasoconstriction and vasodilation
Liver Stimulates glycogenolysis
