Pharmacotherapy

Gabapentin is an antiepileptic drug approved for the treatment of postherpetic neuralgia and as adjunctive therapy for partial seizures. The drug has been shown to be safe and nontoxic. ⋯ We describe the case of a 75-year-old man with renal dysfunction who developed neurologic toxicity due to gabapentin accumulation. Future studies are warranted to confirm the neurologic adverse effects of gabapentin, including any additional risks in patients with renal dysfunction.

Randomized Controlled Trial Comparative Study
Comparison of methods for intravenous infusion of fat emulsion during extracorporeal membrane oxygenation.
To characterize the effects of infusing fat emulsion during neonatal extracorporeal membrane oxygenation (ECMO) by comparing results from patients receiving fat emulsion through the ECMO circuit with those receiving fat emulsion through separate intravenous access. A second goal was to identify the optimal route for administration. ⋯ Although both methods were associated with layering out, agglutination, and clot formation, these effects occurred more frequently with administration into the ECMO circuit, particularly in areas of stasis. This may result in disruption of normal ECMO blood flow and impaired delivery of calories. Fat emulsion should therefore be administered through separate intravenous access during ECMO whenever possible.

Review
Effects of perioperative antiinflammatory and immunomodulating therapy on surgical wound healing.
Patients with various rheumatologic and inflammatory disease states commonly require drugs known to decrease the inflammatory or autoimmune response for adequate control of their condition. Such drugs include nonsteroidal antiinflammatory drugs (NSAIDs), cyclooxygenase (COX)-2 inhibitors, corticosteroids, disease-modifying antirheumatic drugs (DMARDs), and biologic response modifiers. These drugs affect inflammation and local immune responses, which are necessary for proper wound healing in the perioperative setting, thereby potentially resulting in undesirable postoperative complications. ⋯ In some cases, discontinuation of therapy may be required up to 4 weeks before surgery because of the long half-lives of the drugs. In doing so, patients may experience an exacerbation or worsening of disease. Clinicians must carefully evaluate individual patient risk factors, disease severity, and the pharmacokinetics of available therapies when weighing the risks and benefits of discontinuing therapy in the perioperative setting.

Review
Antimicrobial resistance in the hospital setting: impact, trends, and infection control measures.
The growing threat posed by antibiotic-resistant pathogens is a major challenge for infectious disease practitioners and public health officials. In recent years, the prevalence of resistance among key bacterial pathogens, including Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Streptococcus pneumoniae, and Enterococcus sp, has increased at an alarming rate. ⋯ To control the spread of resistance and subsequent impact, a multifaceted approach is warranted. Awareness and surveillance of antimicrobial resistance, prudent use of antibiotics, and compliance with infection control techniques may help contain the emergence and spread of resistant organisms.

To compare the expected costs of short-, intermediate-, and long-term sedation (< 24, 24-72, and > 72 hrs, respectively) with propofol, lorazepam, and midazolam in an intensive care unit. ⋯ Propofol, midazolam, and lorazepam had the lowest expected costs for short-, intermediate-, and long-term sedation, respectively. Many factors aside from drug costs influenced the cost of sedation.
