Evaluation of Neuroleptic Utilization in the Intensive Care Unit During Transitions of Care.

PURPOSE: The purpose of this study was to identify risk factors associated with inappropriate continuation of neuroleptics postdischarge from the intensive care unit (ICU) and hospital. MATERIALS AND METHODS: A retrospective chart review was performed including all patients greater than 18 years of age who received neuroleptic medications in an ICU. RESULTS: One hundred sixty-one patients were included during the 12- month study period. There were 85 (53%) patients discharged from the ICU with inappropriate continuation of a neuroleptic medication. There were 54 (34%) patients discharged from the hospital with inappropriate continuation of a neuroleptic medication. Patients were more likely to be discharged from the ICU with an inappropriate neuroleptic if they were prescribed multiple neuroleptics ( P = .02), did not have a urine drug screen collected at admission ( P = .023), or if trazodone was utilized in their therapy ( P = .004). Patients were more likely to be discharged from the hospital with a neuroleptic if they had multiple neuroleptic orders ( P = .0001) or if trazodone was utilized in their therapy ( P = .0023). CONCLUSION: Risk factors associated with the continuation of inappropriate neuroleptic medications upon discharge from the ICU or the hospital include multiple neuroleptic medications prescribed, the lack of a urine drug screen upon admission, and the utilization of trazodone.

The role of inhaled prostacyclin in treating acute respiratory distress syndrome.

Acute respiratory distress syndrome (ARDS) is a syndrome of acute lung injury that is characterized by noncardiogenic pulmonary edema and severe hypoxemia second to a pathogenic impairment of gas exchange. Despite significant advances in the area, mortality remains high among ARDS patients. High mortality and a limited spectrum of therapeutic options have left clinicians searching for alternatives, spiking interest in selective pulmonary vasodilators (SPVs). Despite the lack of robust evidence, SPVs are commonly employed for their therapeutic role in improving oxygenation in patients who have developed refractory hypoxemia in ARDS. While inhaled epoprostenol (iEPO) also impacts arterial oxygenation by decreasing ventilation-perfusion (V/Q) mismatching and pulmonary shunt flow, this effect is not different from inhaled nitric oxide (iNO). The most effective and safest dose for yielding a clinically significant increase in PaO2 and reduction in pulmonary artery pressure (PAP) appears to be 20-30 ng/kg/min in adults and 30 ng/kg/min in pediatric patients. iEPO appears to have a ceiling effect above these doses in which no additional benefit may be derived. iNO and iEPO have shown similar efficacy profiles; however, they differ with respect to cost and ease of therapeutic administration. The most beneficial effects of iEPO have been seen in adult patients with secondary ARDS as compared with primary ARDS, most likely due to the difference in etiology of the two disease states, and in patients suffering from baseline right ventricular heart failure. Although iEPO has demonstrated improvements in hemodynamic parameters and oxygenation in ARDS patients, due to the limited number of randomized clinical trials and the lack of studies investigating mortality, the use of iEPO cannot be recommended as standard of care in ARDS. iEPO should be reserved for those refractory to traditional therapies.
