tensilon การใช้

The Tensilon test may also be used to predict if neurotoxic paralysis caused by snake envenomation is presynaptic or postsynaptic.
If the neurotoxic is presynaptic then the Tensilon test will show no response and antivenom will not reverse such paralysis.
A tensilon ( edrophonium chloride ) test can be used, which temporarily blocks the breakdown of acetylcholine, and briefly relieves weakness; however, false-negative results are common.
These tests may include a brain scan, cerebrospinal fluid examination, nerve conduction test ( electromyography, or EMG ), and an edrophonium chloride ( Tensilon ) test for myasthenia gravis.
Flaccid paralysis resulting from cholinergic crisis can be distinguished from myasthenia gravis by the use of the drug edrophonium ( Tensilon ), which worsens the paralysis caused by cholinergic crisis, but strengthens the muscle in the case of myasthenia gravis . ( Edrophonium is an cholinesterase inhibitor hence increases the concentration of acetylcholine present ).
