Comparative StudyComparative Study of Drainage and Antibiotics versus Drainage Only in the Management of Primary Subcutaneous Abscesses.
Skin and soft tissue infections are common problems dealt with in emergency departments and medical offices. It is routine practice to prescribe antibiotic agents after incision and drainage of cutaneous abscesses. However, current evidence does not support prescribing oral antibiotic agents after surgical debridement. The aim of the present study was to determine the actual role of antibiotic agents after drainage of cutaneous abscesses. ⋯ Antibiotic agents are not necessary for uncomplicated subcutaneous abscesses after I&D. These cases can be managed safely on an outpatient basis without any increase in morbidity.

Pre-Operative Skin Antisepsis with Chlorhexidine Gluconate and Povidone-Iodine to Prevent Port-Site Infection in Laparoscopic Cholecystectomy: A Prospective Study.
Skin preparation with antiseptic agents is commonly recommended for incisional site cleansing before surgery. We present the result of a prospective case series submitted to a scheduled pre-operative antiseptic procedure combining chlorhexidine gluconate and povidone-iodine before elective laparoscopic cholecystectomy. ⋯ Port-site infections are a common complication after elective laparoscopic cholecystectomy. The proposed pre-operative disinfection procedure is effective in reducing port-site infections. Reducing hospital stay may contribute to limiting the occurrence of this complication.

Risk Factors and Predictive Model Development of Thirty-Day Post-Operative Surgical Site Infection in the Veterans Administration Surgical Population.
Surgical site infection (SSI) complicates approximately 2% of surgeries in the Veterans Affairs (VA) hospitals. Surgical site infections are responsible for increased morbidity, length of hospital stay, cost, and mortality. Surgical site infection can be minimized by modifying risk factors. In this study, we identified risk factors and developed accurate predictive surgical specialty-specific SSI risk prediction models for the Veterans Health Administration (VHA) surgery population. ⋯ Surgery specialty-specific risk factors of 30-day post-operative SSI rates have been identified for a variety of surgery specialties. Accurate SSI risk-predictive surgery specialty-specific SSI predictive models have been developed and validated for the VHA surgery population. These models can be used to develop optimal preventive measures for high-risk patients, patient-centered care planning, and surgical quality improvement.

Sepsis accounts for 10% of intensive care unit admissions and significant healthcare costs. Although the mortality rate from sepsis has been decreasing with better critical care, early identification of septic patients, and prompt interventions, the mortality rate remains 20%-30%. ⋯ Appropriate treatment of sepsis includes prompt identification, early antimicrobial drug therapy, appropriate fluid resuscitation, and initiation of vasopressors in the presence of continued septic shock. Further research needs to be done to better understand the ideal timing of the addition of a second agent and the optimal combinations of vasopressors for individual patients.

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.
