Surgical site infections are common, so effective antibiotic concentrations at the sites of infection, i.e., in the interstitial fluid (ISF), are required. The aim of this study was to evaluate contemporary perioperative prophylactic dosing of cefazolin by determining plasma and subcutaneous ISF concentrations in patients undergoing elective/semielective abdominal aortic aneurysm (AAA) open rep...

Susceptibilities of 259 isolates of pathogenic bacteria to cefazolin were measured by broth and agar dilution procedures. Beta-hemolytic streptococci were inhibited by 0.25 mug/ml, whereas Staphylococcus aureus and alphahemolytic streptococci were inhibited by 2.0 mug/ml. Enterococci were resistant to less than 32 mug/ml. Wide variation was seen with gram-negative species. Most isolates of Kleb...

The empirical combination of both a beta-lactam and glycopeptide to counter potential staphylococcal pathogens may improve the clinical outcomes for cases of Staphylococcus aureus bacteremia. We reported comparative in vitro studies of combination effects of different cephalosporins (i.e., cefazolin, cefmetazole, cefotaxime, and cefepime) combined with glycopeptides for 34 randomly selected met...

The dose and timing of antimicrobial agents given for surgical wound prophylaxis should be based on the concentration-time profile of the drug in tissue at the site of contamination. However, concentrations of antimicrobial agents in surgical wounds are difficult to determine accurately. Since a surgical wound is a unique extravascular compartment with increased vascular permeability and a high...

Ro 13-9904, a new parenteral cephalosporin, was found to have high in vitro activity against Enterobacteriaceae and other gram-negative bacteria, including various isolates resistant to cefuroxime, cefamandole, cefoxitin, and cefazolin. It showed promising activity against Pseudomonas aeruginosa. Although inhibitory against Staphylococcus aureus at concentrations readily achievable in plasma, i...

BACKGROUND Infection is one of the most devastating complications after primary total knee arthroplasty (TKA). Antibiotics-impregnated cement has been used and proven effective in preventing deep infection. This study was to evaluate the long-term results of using cefuroxime-impregnated cement and systemic cefazolin for one week to assess their efficacy in preventing infection of primary TKA. ...

Although intravitreal injection of antibiotics is being used more widely in treatment of bacterial endophthalmitis, the pharmacokinetic principles that underlie such therapy have been derived exclusively from experiments in the rabbit. Therefore, we studied several representative antibiotics in normal eyes of rhesus monkeys. Carbenicillin (1,000 micrograms), cefazolin (1,000 micrograms), or gen...
