Pharmacokinetics and Pharmacodynamics of Antimicrobials in Critically Ill Patients.
Critically ill patients with severe infections often have altered pharmacokinetic and pharmacodynamic variables that lead to challenging treatment decisions. These altered variables can often lead to inadequate dosing and poor treatment outcomes. The pharmacokinetic parameters include absorption, distribution, metabolism, and excretion. ⋯ Altered pharmacodynamics can lead to decreased end-organ perfusion, which can ultimately lead to treatment failure or exposure-related toxicity. The most common antimicrobials utilized in the intensive care unit are classified by the pharmacodynamic principles of time-dependent, concentration-dependent, and concentration dependent with time-dependence. Thus, the aim of this review is to outline pharmacokinetic and pharmacodynamic changes of critically ill patients with severe infections and provide strategies for optimal antibiotic agent dosing in these patients.

Multicenter StudyEffect of the Abdominal Fascial Closure with Triclosan-Coated Sutures in Fecal Peritonitis, on Surgical Site Infection, and Evisceration: A Retrospective Multi-Center Study.
Surgical site infection (SSI) is a frequent complication in dirty surgery, reaching rates of up to 40%. The incidence of SSI might be influenced by the suture used for closure of the abdominal fascia. Sutures coated with antibacterial substances may reduce the bacterial load in the incision. ⋯ Triclosan-coated sutures reduce SSI rate in fecal peritonitis, without differences between braided and monofilament type. The use of monofilament sutures is related to higher risk of evisceration, independent of a triclosan coating.

Development of a Surgical Infection Surveillance Program at a Tertiary Hospital in Ethiopia: Lessons Learned from Two Surveillance Strategies.
Surgical site infections (SSIs) are a leading cause of post-operative morbidity and mortality. We developed Clean Cut, a surgical infection prevention program, with two goals: (1) Increase adherence to evidence-based peri-operative infection prevention standards and (2) establish sustainable surgical infection surveillance. Here we describe our infection surveillance strategy. ⋯ Patient loss to follow-up and poor documentation of infections underestimated overall infectious complications. Direct, prospective follow-up is possible but requires increased time, clinical skill, and training. For accurate surgical infection surveillance, direct follow-up of patients during hospitalization is essential, because chart review does not accurately reflect post-operative complications.

Practice GuidelineA Global Declaration on Appropriate Use of Antimicrobial Agents across the Surgical Pathway.
This declaration, signed by an interdisciplinary task force of 234 experts from 83 different countries with different backgrounds, highlights the threat posed by antimicrobial resistance and the need for appropriate use of antibiotic agents and antifungal agents in hospitals worldwide especially focusing on surgical infections. As such, it is our intent to raise awareness among healthcare workers and improve antimicrobial prescribing. To facilitate its dissemination, the declaration was translated in different languages.

Early Predictors of Abscess Development after Perforated Pediatric Appendicitis.
Approximately one-third of children with appendicitis present with advanced disease or perforation. Whereas this increases the risk for post-operative complications and re-admission, it is not yet possible to predict early on who will develop an abdominal abscess. We sought to identify specific risk factors for this complication, in an attempt to streamline post-operative care. ⋯ Tolerating a regular diet three days after appendectomy for perforated appendicitis decreased the likelihood of a post-operative abscess. No other parameter was predictive of this complication early in the post-operative period. If confirmed in a larger prospective study, this finding may help decrease the length of stay for low-risk patients, and identify abscesses in high-risk patients in a timely fashion.
