Pain, Agitation/Sedation, Delirium, Immobility, Sleep Disruption, and Neuromuscular Blockade
Patient Case
Questions 1 and 2 pertain to the following case.
T.O. is a 70-year-old man just admitted to the ICU with multiple fractures after a motor vehicle accident. His
medical history includes hypertension. He is now agitated after intubation. His laboratory values are normal,
and his vital signs include blood pressure 175/95 mm Hg and heart rate 110 beats/minute.
Which grouping of initial sedatives is most appropriate at this time?
drip with adequate pain control. Which is the best pain management regimen for chest tube removal?
challenging, requiring significant resources and daily discipline from the nursing, medical, and pharmacy
team. Ongoing research has improved our understanding of the consequences of either under- or overtreating
agitation in the ICU, and clinicians should continue to apply this knowledge to their daily selection and
titration of medications. Treatment of a patient who presents with agitation must always begin with attempts
to identify and correct the etiology of the agitation. Common causes of agitation in the ICU include pain,
delirium, hypoxia, hypoglycemia, dehydration, and drug or alcohol withdrawal. Close inspection of
significant patient variables will also help determine the appropriate sedative:
Pain control
Neurologic function: Baseline and acute mental status, history of seizure activity, dementia, psychiatric
history
Clinical variables: Blood pressure, heart rate, respiratory rate
Comorbidities (baseline and acute): Cardiac, renal, hepatic, gastric, pulmonary, pancreatic
Home medication use: Any medication from which a patient could withdraw: Benzodiazepines, opioids,
nicotine, antidepressants, other Ξ³-aminobutyric acid (GABA) receptor agonists
benzodiazepines (usually lorazepam and midazolam) (Table 4). Benzodiazepines are first-line agents for
status epilepticus, alcohol withdrawal, benzodiazepine dependence or withdrawal, and are useful for deep
sedation or amnesia and with the use of neuromuscular blockade. Other indications for benzodiazepines
may exist, which must be scrutinized throughout the ICU stay.
