31
Q

What is the BLACK BOX warning for Fentanyl (sublimaze)?

A

significant abuse potential

32
Q

Special Information for Fentanyl (Sublimaze)

A

What classification is ketamine?

A

dissociative anethetics, induces a trans like effect characterized by analgesia, quietute, and detachment from environment.

36
Q

What classification of drugs is Midazolam (Versed)

A

IV anesthetic, benzodiazepine

37
Q

What is the action for midazolam (Versed)?

A

neuropletic effect, exact action unknown. Acts on limbic, thalmic, and hypothamic regions to cause CNS depression and skeletal muscle relaxation.

38
Q

What are the ADR’s for midazolam (Versed)?

A

Respiratory depression (even arrest), decreased altertness and amnesia, hypotension, hiccups, laryngospasm, loss of dexterity, some have reported muscle tremors, tachycardia, shortness of breath.

39
Q

What is the BLACK BOX warning for midazolam (Versed)?

A

Can cause respiratory depression and arrest.

40
Q

Special Information for Midazolam (Versed).

A

produces anterograde amnesia and loss of memory about procedure, can decrease anxiety. Midazolam can also have a prolonged anesthetic recovery period than barbiturates.

41
Q

What classification is Short-duration-mepivacaine (carbocaine), lidocaine (Xylocaine), and long duration bupicacaine (Marcaine)?

A

They are local anesthetics.

42
Q

What is the action of local anesthetics?

A

Unknown but though to stabilize or elevate the threshold of excitation of nerve cells without affecting the resting potential, thus preventing depolarization and transmission of nerve impulses.

43
Q

What are the ADR’s of local anesthetics?

A

overdosage into CNS from periphery causing excitement, convulsions, and then CNS depression (Bradycardia, hypotension, cardiac arrest) N&V, pallor, apprehension.

44
Q

Special information regarding local anesthetics?

A

Loss of all sensation occurs, starting with pain.
if becomes systemic, has serious CNS depressive effects.
Vasoconstrictors are used to decrease CNS absorption.

45
Q

What is a topical example of a local anesthetic?

A

benzocaine
