Concept explainers
(a)
Interpretation:
The benefits of measuring the amount of serum cholinesterase before the examination.
Concept introduction:
During the examination of cancer, tubes are introduced into the trachea of the patients. Muscles should be relaxed so that tubes can be inserted; therefore, succinylcholine is used. Administration of succinylcholine helps the muscles to relax for a while.
(b)
Interpretation:
The effects on the patients when the activity of serum cholinesterase was only 10 units rather than its normal activity of about 80 units.
Concept introduction:
During the examination of cancer, tubes are introduced into the trachea of the patient. Muscles should be relaxed so that tubes can be inserted; therefore, succinylcholine is used. It helps the muscles to relax for a while.
(c)
Interpretation:
The effect of mutated serum cholinesterase where it displays a Km of 10 mM rather than the normal 1.4 mM.
Concept introduction:
During the examination of cancer, tubes are introduced into the trachea of the patient. Muscles should be relaxed so that tubes can be inserted; therefore, succinylcholine is used. Succinylcholine helps the muscles to relax for a while.
