00:01 So let's wrap up this video on myasthenia gravis. 00:05 It's a chronic autoimmune neuromuscular disease. 00:10 It'll cause weakness in the skeletal muscles which help us breathe, move parts of our body including our arms and legs. 00:16 Now the hallmark of myasthenia gravis is muscle weakness that gets worse after periods of activity and improves after periods of rest. 00:25 So you working with the myasthenia gravis patient is going to be really important for them to understand this concept. 00:31 If they push themselves too much, they're gonna kick themselves into a myasthenia gravis exacerbation. 00:37 Now a degree of muscle weakness including the myasthenia gravis varies greatly from minor to life-threatening respiratory problems. 00:45 We talked about six options for diagnosis: the exam, blood tests which-- remember, if those are might be helpful, might be not. 00:54 Electrodiagnostics, I prefer the single fiber. 00:57 Diagnostic imaging, looking for a thymoma. 01:00 And pulmonary function testing to see where the patient stands and the strengths of their respiratory system. 01:05 So to treat it, we can do the thymectomy. 01:08 Remember that might be helpful, possibly, if the patient has a thymoma, or even doesn't have a thymoma. 01:14 We can give medications like anticholinesterase. 01:18 Those are the ones that are against the enzyme that breaks down acetylcholine. 01:22 Or we can give immunosuppressive drugs. 01:25 So the two medications we would consider: anticholinesterase medications or immunosuppressive drugs. 01:32 But, remember, that really knocks out a patient's immune system from just common diseases we could normally fight off. 01:38 Plasmapheresis and IV immunoglobulin are the ones that involved right into the vascular system. 01:44 Plasmapheresis, you draw all the blood out, put it through a machine, filter out the bad antibodies, put the plasma back that's now clean and improved. 01:53 For IV immunoglobin, we just inject that from antibodies that were collected from a pool of donors, and we injected that to bump up that person's immune system in an appropriate manner. 02:05 Now, last, my myasthenic crisis is a medical emergency. 02:09 So every nurse needs to recognize what are the precursors, what could throw a patient into a myasthenic crisis. 02:16 Now I do know, and we talked about, that we don't always know what the trigger is, but we do know what common triggers are. 02:23 So you being aware of what they are, knowing what to do, is really important that could save someone's life. 02:30 Thank you for watching our video today.

This series of tutorial videos are great and really helpful for nursing students, It's fantastic and I like them pretty much. However, it could be better if each video can goes longer and give a more detailed explanation of some medications which treat a particular disease like how this drug works and how it react in human body to achieve their function.
