Q

What are some de-escalation strategies that can be used if a patient becomes aggressive? What should not be done?

A

De-escalation and escape - while exiting or resolving mild hostility..
DO

  • Keep your tone and body language calm—no sudden movements.
  • Give your patient space.
  • Apologize if you’ve upset them.
  • Empathize and feed back their feelings, e.g. ‘It’s frustrating for you’.
  • Tell them that they are frightening you.
  • Back out. Never turn your back on someone who threatens you.
  • Tell staff immediately.

DON’T

  • Say, ‘Calm down’. This implies that you think they are unreasonably angry; it is inflammatory.
  • Touch them.
  • Make jokes.
  • Stand to ‘match’ a patient who stands; stay seated or back out. If currently standing, don’t stand face to face
  • or put your hands on your hips. Standing to their side, shoulder-on, is less confrontational and makes you a
  • smaller target.

What should be monitored during RT and how often?

A

Response should be monitored within 1 hour.

Also monitor:

  • RR
  • consciousness
  • temperature
  • level of hydration

Intervals determined by senior doctors. If there are preexisting health problems of if maximum dose has been reached then monitor often e.g. every 15 min. This should be documented on NEWS2 chart. If monitoring of sats not possible then do ABCDE assessments.

A
  1. If no ECG
  2. If there is evidence of QTc prolongation, cardiovascular disease, electrolyte abnormalities

19
Q

In what groups should lower doses be used for RT?

A

Elderly: when urgent sedation is required to prevent injury or harm consider:

  • 1st line - Lorazepam 500micrograms to 1mg IM, not more frequently than every 1 hours (maximum 2 mg in 24 hours).
  • 2nd line - Promethazine IM 12.5mg plus haloperidol IM 500micrgrams to - 1mg. Repeat if necessary no more frequently than every 2 hours (promethazine maximum 50mg in 24 hours. Haloperidol maximum 5mg in 24 hours).

NB: antipsychotics should be used with caution in dementia and increase the risk of stroke.

  • 1st line - Lorazepam 500micrograms to 1mg IM, repeated not more frequently than every 1 hours (maximum 2 mg in 24 hours).
  • 2nd line - Promethazine IM 12.5mg plus haloperidol IM 3-5mg. Repeat no more frequently than every 2 hours (promethazine maximum 50mg in 24 hours. Haloperidol maximum 12mg in 24 hours).
