RESUMEN
BACKGROUND: Droperidol is a butyrophenone, with antiemetic, sedative, anxiolytic, and analgesic properties. Although droperidol was once widely used in both emergency and perioperative settings, use of the medication declined rapidly after a 2001 U.S. Food and Drug Administration (FDA) boxed warning called the medication's safety into question. OBJECTIVE: The purpose of this clinical review was to provide evidence-based answers to questions about droperidol's safety and to examine its efficacy in its various clinical indications. DISCUSSION: Droperidol is an effective sedative, anxiolytic, analgesic, and antiemetic medication. As a sedative, when compared with haloperidol, droperidol has faster onset, as well as greater efficacy, in patients experiencing acute psychosis, with no increase in adverse events. As an antiemetic, droperidol has been found to have equal or greater efficacy in reducing nausea and vomiting than ondansetron and metoclopramide, with similar adverse effects and the added effect of reducing the need for rescue analgesia in these patients. As an analgesic, droperidol is effective for migraines and has opioid-sparing effects when used to treat abdominal pain. Droperidol is a particularly useful adjunct in patients who are opioid-tolerant, whose pain is often difficulty to manage adequately. CONCLUSIONS: Droperidol seems to be effective and safe, despite the boxed warning issued by the FDA. Droperidol is a powerful antiemetic, sedative, anxiolytic, antimigraine, and adjuvant to opioid analgesia and does not require routine screening with electrocardiography when used in low doses in otherwise healthy patients before administration in the emergency department.

BACKGROUND & AIMS: Chronic infection with hepatitis B or C virus (HBV or HCV) is a leading cause of cirrhosis by unknown mechanisms of pathogenesis. Translocation of gut microbial products into the systemic circulation might increase because of increased intestinal permeability, bacterial overgrowth, or impaired clearance of microbial products by Kupffer cells. We investigated whether the extent and progression of liver disease in patients with chronic HBV or HCV infection are associated with microbial translocation and subsequent activation of monocytes. METHODS: In a retrospective study, we analyzed data from 16 patients with minimal fibrosis, 68 with cirrhosis, and 67 uninfected volunteers. We analyzed plasma levels of soluble CD14 (sCD14), intestinal fatty acid binding protein, and interleukin-6 by enzyme-linked immunosorbent assay, and lipopolysaccharide (LPS) by the limulus amebocyte lysate assay, at presentation and after antiviral treatment. RESULTS: Compared with uninfected individuals, HCV- and HBV-infected individuals had higher plasma levels of LPS, intestinal fatty acid binding protein (indicating enterocyte death), sCD14 (produced upon LPS activation of monocytes), and interleukin-6. Portal hypertension, indicated by low platelet counts, was associated with enterocyte death (P=.045 at presentation, P<.0001 after therapy). Levels of sCD14 correlated with markers of hepatic inflammation (P=.02 for aspartate aminotransferase, P=.002 for ferritin) and fibrosis (P<.0001 for γ-glutamyl transpeptidase, P=.01 for alkaline phosphatase, P<.0001 for α-fetoprotein). Compared to subjects with minimal fibrosis, subjects with severe fibrosis at presentation had higher plasma levels of sCD14 (P=.01) and more hepatic CD14+ cells (P=.0002); each increased risk for disease progression (P=.0009 and P=.005, respectively). CONCLUSIONS: LPS-induced local and systemic inflammation is associated with cirrhosis and predicts progression to end-stage liver disease in patients with HBV or HCV infection.
