Pain control is essential to quality patient care. It ensures patient comfort, promotes pulmonary toilet, and prevents exacerbation of tachycardia and hypertension.

Morphine sulfate (Astramorph, Infumorph, Duramorph)

Morphine is the drug of choice for narcotic analgesia because of its reliable and predictable effects, safety profile, and ease of reversibility with naloxone. Like fentanyl, morphine sulfate is easily titrated to the desired level of pain control. Morphine sulfate administered IV may be dosed in a number of ways. It is commonly titrated until the desired effect is obtained.

Fentanyl citrate

Fentanyl citrate is a synthetic opioid that has 75-200 times more potency of and a much shorter half-life than morphine sulfate. It has fewer hypotensive effects than morphine and is safer in patients with hyperactive airway disease because of minimal or no associated histamine release. By itself, fentanyl citrate causes little cardiovascular compromise, although the addition of benzodiazepines or other sedatives may result in decreased cardiac output and blood pressure.

Fentanyl citrate is highly lipophilic and protein-bound. Prolonged exposure to it leads to accumulation of the drug in fat and delays the weaning process. Consider continuous infusion because of the medication's short half-life.
