|---|---|---|---|---|---|
| show | The neuromuscular junction.
🗑
|
||||
| show | By blocking transmission across the neuromuscular junction(NMJ).
🗑
|
||||
| show | By nerve stimulation.
🗑
|
||||
| Succinylcholine causes depolarization of the end plate just like... | show 🗑
|
||||
| show | Prolonged depolarization.
🗑
|
||||
| Non-depolarizing neuromuscular blockers bind to the acetylcholine receptor site. How does this change the receptor site? | show 🗑
|
||||
| show | A nerve stimulator.
🗑
|
||||
| Other than assessing the effects of our NMBD, why else do we use nerve stimulators? | show 🗑
|
||||
| show | 1 cycle/sec, duration of 0.2 sec.
🗑
|
||||
| show | All muscles innervated by it will respond.
🗑
|
||||
| Why should we avoid directly stimulating the muscle fiber with a nerve stimulator? | show 🗑
|
||||
| show | Over the course of a nerve.
🗑
|
||||
| show | Response to stimulation.
🗑
|
||||
| How do we decrease resistance when placing nerve stimulator electrodes? | show 🗑
|
||||
| At the beginning of muscle relaxation therapy, it is important to get what? | show 🗑
|
||||
| show | Abdominal sx: TOF 1/4. Even with TOF 2/4 or 3/4, should be able to maintain adequate relaxation with good anesthesia.
🗑
|
||||
| How many twitches are necessary for reversal? | show 🗑
|
||||
| What is better to assess reversal, TOF or single twitch? | show 🗑
|
||||
| show | False.
🗑
|
||||
| show | Single twitch, double burst, train of four(TOF), and tetany.
🗑
|
||||
| What frequency is single twitch usually delivered at? | show 🗑
|
||||
| show | As a control twitch, to which subsequent twitches are compared.
🗑
|
||||
| How is your assessment of single twitch expressed? | show 🗑
|
||||
| TOF is four successive twitches. How many hertz and how long? | show 🗑
|
||||
| TOF is expressed as... | show 🗑
|
||||
| show | Relaxation increases.
🗑
|
||||
| How does TOF respond to 100% receptor blockade? | show 🗑
|
||||
| show | No twitches but diaphragm may move.
🗑
|
||||
| show | 90%. This is adequate relaxation for abdominal procedures.
🗑
|
||||
| Your patient has 4 twitches on TOF; VC and TV can be normal. How much of his receptors can still be blocked? | show 🗑
|
||||
| It is possible to pass inspiratory pressure test with how much receptor blockade? | show 🗑
|
||||
| show | A sustained contraction of 5sec.usually at 50 or 100 Hz.
🗑
|
||||
| show | Adequate recovery from blockade.
🗑
|
||||
| show | Consists of three short high frequ. Bursts (50 Hz) separated by 0.2 msec followed 750 msec later by another three of the same.
🗑
|
||||
| show | Double burst.
🗑
|
||||
| show | Two twitches; diminished; no fade
🗑
|
||||
| Your patient has a non-depolarizing block on board and you've just administered double burst. What will you see? | show 🗑
|
||||
| True or false: an intubating dose of Succinylcholine will leave your patient still able to respond to TOF 1/4. | show 🗑
|
||||
| show | 2.5 minutes.
🗑
|
||||
| 2.5 minutes after giving Succinylcholine, when the NMJ begins to recover, what will be the response to TOF stimulation? | show 🗑
|
||||
| show | A tetanic stimulus (50 per second) will produce a tetanic response of small but sustained intensity.
🗑
|
||||
| show | TOF stimulus applied after the tetanic stimulus produces a muscle response equal in intensity and character to the original series of stimuli.
🗑
|
||||
| show | True.
🗑
|
||||
| True or false: After administering an intubating dose of non-depolarizing muscle relaxant, response to TOF will usually disappear, and time to recovery depends on the agent used. | show 🗑
|
||||
| After giving a non-depolarizing muscle relaxant, what is response to tetany? | show 🗑
|
||||
| show | Response to TOF following tetanus is increased, yet still diminishes as before.
🗑
|
||||
| What muscle is stimulated by the ulnar nerve? | show 🗑
|
||||
| Where is the ulnar nerve found? | show 🗑
|
||||
| show | Orbicularis oculi.
🗑
|
||||
| show | The diaphragm and laryngeal adductors.
🗑
|
||||
| What does stimulation of the post tibial nerve cause? | show 🗑
|
||||
| What muscle does the mandibular nerve stimulate? | show 🗑
|
||||
| show | Electrode in front of and below zygomatic arch and forehead.
🗑
|
||||
| show | Laryngeal, abdominal, and diaphragmatic muscles.
🗑
|
||||
| Because it is not one of the first to recover, what is the best muscle to monitor for reversal? | show 🗑
