The in vitro bactericidal activity of cefazolin was found to be similar to that of cephaloridine and cephalothin but slightly greater than that of cephalexin against a majority of 233 strains of gram-positive and gram-negative organisms. Cefazolin, however, was two- to eightfold more active than the other two drugs against Escherichia coli and klebsiella. The mean peak concentrations in the ser...
Treatment of rats with cefazolin in vivo significantly suppressed activity of alanine and aspartate aminotransferases in serum and in the liver, brain, kidney, and heart. Simultaneous administration of pyridoxal further reduced enzyme activity except in the liver, where there was no change. Pyridoxal 5'-phosphate partly reversed the decreased enzyme activity in the serum, liver, and kidney, but...
conclusions due to the good tolerance of patients towards topical anesthesia, pouring a drop of povidone-iodine 10% seems to be a simple and acceptable method to reduce the growth of microorganisms of the conjunctiva. background postoperative endophthalmitis is one the most serious complications of cataract surgery. the majority of causative organisms in this destructive infection come from the...
Several studies have previously reported synergistic effects between vancomycin and a given beta-lactam or a given aminoglycoside against methicillin-resistant Staphylococcus aureus (MRSA) strains. The aim of our study was to exhaustively compare the effects of different combinations of a beta-lactam, vancomycin, and/or an aminoglycoside against 32 clinical MRSA strains with different aminoglyc...
OBJECTIVES As morbidly obese patients are prone to surgical site infections, adequate blood and subcutaneous tissue concentrations of prophylactic antibiotic agents during surgery are imperative. In this study we evaluated cefazolin subcutaneous adipose tissue distribution in morbidly obese and non-obese patients, thereby quantifying the influence of morbid obesity on cefazolin pharmacokinetics...
Routine us of vancomycin for perioperative prophylaxis is discouraged, principally to minimize microbial resistance to it. However, outcomes and costs of this recommendation have not been assessed. We used decision-analytic models to compare clinical results and cost-effectiveness of no prophylaxis, cefazolin, and vancomycin, in coronary artery bypass graft surgery. In the base case, vancomycin...
The penetration of cefonicid and cefazolin into cardiac tissue was compared after a single 30-mg/kg dose in 30 patients undergoing aortocoronary artery bypass graft surgery. Samples of the right atrial appendage, pericardial fluid, and serum were obtained at various times and assayed for drug content. The concentrations of cefonicid in serum and the atrial appendage were at least twice those ob...
patients and methods for this clinical trial, patients with fever plus either dysuria, frequency, flank pain or flank tenderness were enrolled. having performed urinalysis (u/a), urine culture (u/c) and antibiogram, they were randomly assigned in two groups: ceftriaxone 1gr twice a day or cefazolin 1gr trice a day. three days later, urine was re-evaluated and patients were categorized as clinic...
OBJECTIVE Post-craniotomy seizure (PCS) is reported only rarely. However, our department noted a 433% increase in PCS for a year beginning September 2010, especially after cerebrovascular surgery. Our goal was to identify the cause of our unusual outbreak of PCS. METHODS For almost one year after September 2010, cases of PCS increased significantly in our department. We analyzed 973 patients ...
CONTEXT Perioperative antibiotic prophylaxis during elective cesarean delivery at term to reduce postoperative maternal infectious morbidity is generally used but may not be effective on the basis of the available data. Also, the optimal timing of prophylactic antibiotic administration is unclear. OBJECTIVE To compare the effectiveness of cefazolin administered before skin incision vs cefazol...
