42
Q

what should be administered prior to ketamine

A

Prior to administering ketamine for pain, sufficient fentanyl should be administered so that further doses are not providing additional analgesia. This will usually require 150-200 mcg of fentanyl for an adult.

43
Q

ketamine mechnism

A
  • Ketamine is an analgesic. It has complex actions, but is predominantly an N-methyl-d-aspartate (NMDA) receptor antagonist (blocker), resulting in inhibition of excitatory neurotransmitters in the brain.
  • Low doses cause analgesia, larger doses cause amnesia and dissociation, and high doses cause anaesthesia.
44
Q

fent mechnism

A
  • Fentanyl is an opiate analgesic. It is an opiate agonist (or stimulator) that binds to opiate receptors in the brain and spinal cord causing analgesia.
45
Q

explain why midoazolam can be used as a pain relief

A

Midazolam does not have analgesic properties. However, midazolam has a role in reducing pain associated with severe muscle spasm or severe anxiety particularly if the patient has severe back pain or a dislocated joint.

46
Q

what should occur prior to administering midaolam for pain relief

A

Prior to administering midazolam for pain, sufficient fentanyl should be administered that further doses are not providing additional analgesia. This will usually require 150-200 mcg of fentanyl for an adult.

47
Q

midazolam mechanism

A
  • Midazolam is a benzodiazepine.
  • Midazolam enhances the activity of gamma-aminobutyric acid (GABA) at GABA receptors within the central nervous system, resulting in anticonvulsant activity, sedation, amnesia, anxiolysis and muscle relaxation.
48
Q

what is the goal of a fascia iliaca block

A

The goal of a fascia iliaca block is to provide additional analgesia and reduce the need for fentanyl and/or ketamine, particularly if the patient is elderly and/ or frail. It is uncommon for the block to produce complete control of pain and in approximately 25% of patients the block will have no discernible effect.
