Analgosedation Method in the ICU: This method of sedation advocates the use of opiate medications before
prescribing an anxiolytic/hypnotic medication to provide patient comfort in the ICU unless anxiolytics
are otherwise indicated. The PADIS guidelines recommend analgosedation (analgesia is used before a
sedative to reach the sedative goal) or analgesia-based sedation (an opioid is used instead of a sedative to
reach the sedative goal). Providing pain relief early in the ICU stay may decrease the agitation associated
with pain and/or general discomfort while minimizing the use of alternative medications commonly used
for agitation (e.g., benzodiazepines). The guidelines recognize that current data using analgosedation are
primarily limited to open-label trials, using remifentanil as the analgesic, and mostly conducted in Europe,
where critical care staffing and management practices differ from those in the United States. Despite these
limitations, it remains notable that studies using the analgosedation method found a significant decrease in
benzodiazepine dosage requirements when opiates were the primary medications used for discomfort and
agitation. This is a positive step in decreasing the untoward adverse effects of the benzodiazepine class
of sedatives. There is a potential for high cumulative doses of opiates with the analgosedation method,
necessitating daily monitoring of their adverse effects (e.g., respiratory depression, altered mental status, GI
slowing). Opioid use in the ICU also increases the daily risk of delirium development in a dose dependent
manner.
sedation (bolus doses of morphine) and light sedation (propofol for 48 hours then midazolam titrated to a
RASS of β2 to β3). There was no difference in 90-day mortality between groups (no sedation 148 [42.4%]
vs. light sedation 130 [37%]; 95% CI β2.2 to 12.2; p=0.65). However, 27% of the no-sedation group crossed
over to receive sedation during the first 24 hours after randomization.
