  • While injecting – Stop if there is high resistance

7. Monitoring

Peak Absorption/Effect: 15-30min

  1. Observable Cubical
  2. Cardiac Monitor
  3. Obs: 5, 10, 15, 30 min

8. Local Anaesthetic Toxicity  – here

9. Unable to Block?

Our aim within the ED is to offer a Block to ALL NoF patients. However in some cases such as Anticoagulated patients there is a relative contraindication to performing a Block and the ED senior may decide that we are unable to perform this within the ED. In these cases:

If you have a #NoF patient who you feel we wont be able to offer a Never Block in ED (please escalate to)

  • Monday to Friday 0900-1700 please call theatre 5 and ask for the consultant anaesthetist of the day. (they are often doubled up)
  • Weekend and OOH call the CEPOD anaesthetist. -LIMITED USEFULLNESS
    • Unfortunately this is a junior who probably cant do blocks themselves
    • However if their consultant is in they might be able to help , (but not all of them can do block)

You should receive a decision from anaesthetics promptly <30min as to weather this will be possible
