19. Sequelae of Delirium After Hospital Discharge During the ICU/Hospital Stay - Increased mortality - 3x greater re-intubation rate - Average 10 additional days in hospital - Higher costs of care - Increased mortality - Long-term cognitive impairment - D/c requirement for chronic care facility - Decreased functional status at 6 months Milbrandt EB, et al.

Notes de l'éditeur
CONSCIOUS SEDATION (Ability to make cognitive evaluation) A sedation goal or endpoint should be established and regularly redefined for each patient. Regular assessment and response to therapy should be systematically documented. Give examples of Insulin, Pressors and how we titrate to endpoint Grade of recommendation = C The use of a validated sedation assessment scale is recommended. Grade of recommendation = B A sedation goal or endpoint should be established and regularly redefined for each patient. Regular assessment and response to therapy should be systematically documented. Grade of recommendation = C
An acute brain dysfunction
Delirium is a syndrome of acute organ dysfunction. While “respiratory failure” is the most common reason for ICU admission, delirium (i.e., brain “failure”) is the number one organ dysfunction Three take home messages with this slide: 1. The DSM IV-TR14 and the CAM-ICU define delirium as noted in Figure 1 ,15 which distinguishes delirium from coma 2.Criteria for delirium diagnosis, highlights the cardinal symptoms of delirium 3. A dashed line encircles optional symptoms of delirium (i.e. those sometimes present but not mandatory for a diagnosis of delirium). Hallucinations equal not normal Missing a lot if we wait to see hallucinations
Up to 75% of delirium missed if a tool is not used…Most delirium is invisible unless you look for it
Not a lot of great data to describe which are highly associated with delirium Benzos are a strong association
Investigator initiated- D-RCT, with the investigators holding the FDA IND
Sedation with dexmedetomidine in SEDCOM was safe (for up to 28 days, which is different than the currently approved 24-hour period) Max Dose: 1.4mcgs/kg/hr
There was no difference between dexmedetomidine and midazolam in time at targeted sedation level in mechanically ventilated ICU patients. At comparable sedation levels, dexmedetomidine-treated patients spent less time on the ventilator, experienced less delirium, and developed less tachycardia and hypertension.
Under-sedated in florid ARDS, increase drug delivery (gtt likely best approach), mobilize
Over-sedated and delirious, stop sedation, daily wake-up, mobilize, cognitive stimulation, sleep preservation, sensory stimulation, tight titration Reorientation and cognitive stimulation Talk about family, friends, current events Convey day, date, place Reason for hospitalization Hearing aids and/or eye glasses Pain management Sleep preservation Maintain sleep hygiene Minimize interruptions Maintain vent synchrony Promote comfort and relaxation
Need to think about cause of delirium, consider antipsychotics, mobilize, Reorientation and cognitive stimulation Talk about family, friends, current events Convey day, date, place Reason for hospitalization Hearing aids and/or eye glasses Pain management Sleep preservation: Maintain sleep hygiene, Minimize interruptions, Maintain vent synchrony, Promote comfort and relaxation THINK T oxic Situations CHF, shock, dehydration Deliriogenic meds (Tight Titration) New organ failure, e.g, liver, kidney H ypoxemia; also, consider giving H aloperidol or other antipsychotics I nfection/sepsis (nosocomial), I mmobilization N onpharmacological interventions Hearing aids, glasses, reorient, sleep protocols, music, noise control, ambulation K + or Electrolyte problems
