title: Optimum sedation and analgesia in critical illness: we need to keep trying.
abstract: Many studies have documented patients' distressing recollections of the intensive care unit (ICU). The study by van de Leur and colleagues, conducted in a group of surgical ICU patients with moderate severity of sickness, found that the frequency of such unpleasant memories was increased in those able to recall factual information about their stay in the ICU. The study did not include sedation scoring but it did use a simple tool to assess factual recall. This tool appeared reliable and could be easily applied in any ICU. Previous work strongly suggests that abolishing memory of ICU by using deep sedation would not be an appropriate response to these findings. Rather, we need to work on strategies that reduce distress by improving analgesia, reducing noxious stimuli (if possible) and, potentially, using pharmacology to produce a calm patient with minimal sedation. Achieving the latter is rarely possible today but it might become possible with future drug development.
