1 hour at least
137
What is the convention for IM tranquilisation in an unknown/ neuroleptic naïve patient?

IM Lorazepam - wait 30 mins for a response If response only partial - repeat IM lorazepam dose If no response: WAIT until >1hr since lorazepam, then give IM olanzapine OR IM haloperidol with promethazine (note - check there is no cardiac disease with ECG) Acronym for orders of anti-psychotics = Lots Of Hallucinations AND Panic (Lorzaepam, Olanzapine, Haloperidol AND promethazine)
138
What is the most important factor to guide use of IM medication for rapid tranq in a known patient/ patient with a confirmed history of antipsychotic use?
Presence/ absence of cardiac disease
139
What is the convention for administering IM tranquilisation in a known patient with NO cardiac disease?
Start with haloperidol with promethazine (think - makes sense that last thing on rapid tranq ladder (L-->O --> P+H) is for patients who are known and definitely do not have cardiac disease) - Wait 30 mins for response and repeat if response only partial If no response: lorazepam (if not already used) or olanzapine
140
What is the convention for administering IM tranquilisation in a known patient WITH cardiac disease?
1. Lorazepam - wait 30 mins for response OR olanzapine (repeat if partial response) 2. If no response: wait 1 hour, then give lorazepam/ olanzapine
141
Recall the dosing for oral rapid tranquilisation medications
Lorazepam: 1-2mg (max in 24 hours = 4mg) Olanzapine: 5-10mg (max in 24 hours = 20mg) Haloperidol: 5-10mg (max in 24 hours = 20mg) Promethazine: 25-50mg (max in 24 hours = 100mg)

154
How is depression treated in children and young people?
If mild, watchful waiting, self-help and lifestyle advice If moderate-severe: - 5-11 y/os = family therapy, IPT/ individual CBT, referral made through CAMHS - 12-18 y/os = psychological intervention, probably individual CBT, if really bad + fluoxetine Must try and avoid medication if at all possible Intensive psychological therapy thorugh CAMHS if completely unresponsive to treatment
155
How is depression treated in adults?
Check suicide risk Step one: if initial suspected depression / subthreshold symptoms --> watchful waiting, with follow up in 2 weeks, education about sleep/ mind.co.uk etc Step two: if persistent subthreshold/ mild symptoms: group/ computerised CBT/ guided self-help - only give medication if subthreshold symptoms last longer than 2 years Step three: moderate symtoms/ persistent subthreshold refractory to step 2: individual CBT/IAPT + medications with regular review every 2 weeks for 3 months (or every week if suicidal ) Step four: severe depression/ risk to life/ neglect: high-intensity psychsocial interventions, section if necessary, medications, ECT if necessary
