• Is it possible?
• How? What are the alternatives?

PADIS GuidelinesCCM Sept 2018
• We suggest using light sedation (vs deep sedation) in critically ill, mechanically ventilated adults (conditional recommendation, low quality of evidence)
• In critically ill, intubated adults, DSI protocols and NP-targeted sedation can achieve and maintain a light level of sedation (ungraded)
• We suggest using propofol over a benzodiazepine for sedation in mechanically ventilated adults after cardiac surgery (conditional recommendation, low quality of evidence)
• We suggest either propofol or dexmedetomidine over benzodiazepines for sedation in critically ill, mechanically ventilated adults (conditional recommendation, low quality of evidence)

Co-operation and communication
• 4 multicentre trials (N=1461) compared dex with midazolam or propofol
• Secondary outcomes: nurses’ assessment of arousal, co-operation and ability to
communicate pain using VAS
• In all 4 trials patients who received dex were significantly more arousable, more co-
operative and better able to communicate their pain than those who received propofol or
midazolam (p ≤ 0.001 in all cases)

Essentials of comfort management - 1
• Keep your patients awake and engaged
• Symptom based management
• Pain, anxiety, agitation, sleep
• Intermittent/prn rather than continuous
• Analgesia-first strategy
– Objective assessment of pain
– Minimal or no sedation
![Page 38: Sangeeta Mehta MD, FRCPC CCCF Nov 9, 2018 · 2019-09-27 · Sangeeta Mehta MD, FRCPC CCCF Nov 9, 2018 Comfort without sedation. Disclosures • I have no disclosures or conflicts](https://reader034.vdocuments.mx/reader034/viewer/2022042309/5ed6401c0c1f140c715b54b9/html5/thumbnails/38.jpg)
Essentials of comfort management - 2
• De-medicalize/mobilize
• Non-pharmacologic support
• Family presence
• If sedation is needed
– Favour propofol/dexmedetomidine
– Use adjunctive agents
• Be vigilant for iatrogenic withdrawal
• Sleep promotion

• Anxiety because I felt I needed to get my restraints off
• A nurse - a man - he came and tied my hands really tight
• When in restraints thought an electronic [slruder] treatment was
coming
• I was terrified for my life. I felt restrained.
• Dream that someone was hand cuffing pt to a table/chair
• Pt remembers being restrained & pleading to have restraints
removed
• A male nurse tied my hand very tight after I called him over to help
me turn as I was very uncomfortable
• The feeling of restraint was upsetting and made him feel violated.
Felt he was yelled at
• Saw images of vampires who tied her arms down in order to suck
blood from her central line
