Pharmacotherapy
-
To assess the effect of substituting dexmedetomidine for propofol during a nationwide propofol shortage on postoperative time to extubation and opioid requirements in patients who underwent coronary artery bypass graft (CABG) surgery. ⋯ No statistically significant differences were noted between the propofol and dexmedetomidine groups when assessing the outcomes of opioid requirements and the time to extubation. A multicenter, prospective, randomized, blinded study is needed to determine the optimal sedative after CABG surgery.
-
To determine the incidence of Clostridium difficile infection (CDI) at one community hospital by identifying patients with stool samples positive for C. difficile toxin A or B, and to compare the incidence with a 2008 national estimate; and to determine which patient characteristics and concomitant antimicrobial and acid-suppression drugs are risk factors for the development of CDI. ⋯ The incidence of CDI in 2009 at one community hospital was significantly lower than a 2008 national estimate. Antimicrobial and acid-suppression therapies--in particular, combinations of fluoroquinolones, cephalosporins, carbapenems, and proton pump inhibitors--were found to be risk factors for the development of CDIs in hospitalized patients.

The United States Food and Drug Administration (FDA) Amendments Act of 2007 mandated that Risk Evaluation and Mitigation Strategies (REMS) be required of manufacturers. These REMS are strategies implemented to manage known or potential risks associated with drugs and to ensure ongoing pharmacovigilance throughout the life of a pharmaceutical product, including once the product becomes available as generic. The elements of an individual REMS program consist of three levels: medication guide or patient package insert, communication plan, and elements to assure safe use (ETASU). ⋯ The REMS are a permanent fixture in the development and marketing of pharmaceutical agents, and their further implementation in solid organ transplantation is inevitable. Transplantation providers should take a proactive role in patient education and implementation of REMS within the therapeutic area. It is imperative for health care providers to realize that the ultimate goals of REMS are to reduce the potential for serious risks and to make outcomes from the treatment of disease more predictable.

To characterize the extent that serum gentamicin concentrations are associated with hearing loss indicated by otoacoustic emission (OAE) screen failure in critically ill neonates receiving gentamicin in accordance with a high-dose, extended-interval dosing protocol. ⋯ Neonates weighing more than 1500 g at birth and whose gentamicin C(max) exceeded 10 μg/ml were at an increased risk for OAE screen failure. Monitoring and maintaining gentamicin C(max) at or below 10 μg/ml may minimize hearing impairment; however, further studies are necessary.
