Compatibility Of Vancomycin And Oxacillin During Simulated Y-Site Delivery, Chad A. Knoderer, Hilary M. Teibel, Kristen R. Nichols
Chad A. Knoderer
Background: Vancomycin and oxacillin may be used together as empiric coverage in patients with proven or suspected Staphylococcus aureus infections. Though vancomycin hydrochloride 20 mg/mL and oxacillin sodium 160 mg/mL are reported to be compatible via Y-site delivery, Y-site compatibility of commonly used concentrations, vancomycin 10 mg/mL and oxacillin 20 mg/mL, has not yet been reported. Objective: To determine the Y-site compatibility of vancomycin 10 mg/mL and oxacillin 20 mg/mL. Methods: One vancomycin hydrochloride 1 g vial was reconstituted with 10 mL sterile water for injection (SWFI) and diluted with 90 mL 5% dextrose in water (D5W) in an evacuated …
Optimizing Guideline-Recommended Antibiotic Doses For Pediatric Infective Endocarditis, Chad A. Knoderer, Kristen R. Nichols, Emily N. Israel, Christopher A. Thomas
Optimizing Guideline-Recommended Antibiotic Doses For Pediatric Infective Endocarditis, Chad A. Knoderer, Kristen R. Nichols, Emily N. Israel, Christopher A. Thomas
Chad A. Knoderer
The American Heart Association recently published an updated scientific statement on the management of infective endocarditis in childhood. The recommendations included for vancomycin, aminoglycoside, and β-lactam dosing and monitoring are based primarily on expert opinion and do not consider available evidence for dose optimization based on pharmacokinetic and pharmacodynamic principles in pediatric patients. This is concerning because even when clinically necessary, some practitioners may be hesitant to deviate from guideline-recommended doses. In this perspective, we highlight potential areas for improvement in the statement-recommended doses and summarize evidence supporting antibiotic dosing optimization. The addition of a pediatric clinical pharmacist with expertise …

Success With Extended-Infusion Meropenem After Recurrence Of Baclofen Pump-Related Achromobacter Xylosoxidans Meningitis In An Adolescent, Kristen R. Nichols, Chad A. Knoderer, Nicholas G. Jackson, John J. Manaloor, John C. Christenson
Chad A. Knoderer
A 13-year-old female experienced a recurrence of baclofen pump-related central nervous system (CNS) infection caused by Achromobacter, despite absence of retained foreign material. Due to the failure of meropenem (120 mg/kg/d in divided doses every 8 hours and infused over 30 minutes) in the initial infection, the dose was infused over 4 hours during the recurrence. Meropenem is an antibiotic for which efficacy is time dependent, and 4-hour versus 30-minute infusions have been shown to prolong the time the concentration of the antibiotic exceeds the minimum inhibitory concentration (MIC) of the organism at the site of infection (T>MIC). Meropenem …

Vancomycin And Gentamicin Pharmacokinetic Alterations In An Adolescent Amputee, Kristen R. Nichols, Kari M. Edison, Michelle D. Rosenbaum, Chad A. Knoderer
Vancomycin And Gentamicin Pharmacokinetic Alterations In An Adolescent Amputee, Kristen R. Nichols, Kari M. Edison, Michelle D. Rosenbaum, Chad A. Knoderer
Chad A. Knoderer
A 14-year-old male with bilateral above-the-knee amputations presented to our hospital for treatment of a skin and soft-tissue infection. We report the experience of vancomycin and gentamicin therapy in this patient. Because these medications require weight-based dosages and pharmacokinetic monitoring of serum levels, it was necessary to obtain peak and trough levels of the two drugs in order to determine the pharmacokinetic differences in this patient compared to those in an adolescent male without amputations. To our knowledge, this is the first report describing pharmacokinetic differences in an adolescent amputee.
Cinacalcet Administration By Gastrostomy Tube In A Child Receiving Peritoneal Dialysis, Kristen R. Nichols, Chad A. Knoderer, Bethanne Johnston, Amy C. Wilson
Cinacalcet Administration By Gastrostomy Tube In A Child Receiving Peritoneal Dialysis, Kristen R. Nichols, Chad A. Knoderer, Bethanne Johnston, Amy C. Wilson
Chad A. Knoderer
A 2-year-old male with chronic kidney disease with secondary hyperparathyroidism developed hypercalcemia while receiving calcitriol, without achieving a serum parathyroid hormone concentration within the goal range. Cinacalcet 15 mg (1.2 mg/kg), crushed and administered via gastrostomy tube, was added to the patient’s therapy. This therapy was effective in achieving targeted laboratory parameters in our patient despite instructions in the prescribing information that cinacalcet should always be taken whole.

Use Of Sildenafil To Facilitate Weaning From Inhaled Nitric Oxide In Children With Pulmonary Hypertension Following Surgery For Congenital Heart Disease, Jaclyn E. Lee, Simon C. Hillier, Chad A. Knoderer
Chad A. Knoderer
Pulmonary hypertension frequently complicates the postoperative management of patients after congenital cardiac surgery. Inhaled nitric oxide is an effective treatment option, but rebound pulmonary hypertension can occur upon its withdrawal. Sildenafil may facilitate its withdrawal by restoring cyclic guanosine monophosphate availability via phosphodiesterase-5 inhibition. The purpose of this study was to evaluate the use of sildenafil in facilitating weaning from inhaled nitric oxide after congenital cardiac surgery in patients who had previously failed weaning, and to compare the effects of sildenafil on pulmonary and systemic hemodynamics. Children who received sildenafil after cardiovascular surgery during a 23-month period at Riley Hospital …

Cox, Chad A. Knoderer, Aimee Jennings, John W. Brown, Mark D. Rodefeld, Scott G. Walker, Mark W. Turrentine
Chad A. Knoderer
We conducted a randomized, controlled clinical trial to determine whether a difference in catheter-associated blood stream infection (CABSI) incidence existed between children who underwent cardiac surgery and had a central venous catheter impregnated with minocycline and rifampin versus those who had a conventional, nonimpregnated catheter after cardiac surgery. Due to a lower number of infections than expected, the study was terminated early. Among 288 evaluable patients, the rates of CABSI and line-related complications were similar between the 2 groups.

Chad A. Knoderer
Background In 2008, the empiric vancomycin dosing recommendation in children at our institution was changed from 40 to 60 mg/kg per day. Subsequently, an increased incidence of acute kidney injury (AKI) in patients receiving vancomycin was suspected. The objective of this study was to evaluate AKI in children receiving vancomycin and to determine risk factors for AKI development. Methods Medical records of patients aged 30 days through 17 years who received vancomycin for at least 72 hours between January and December 2007 (40 mg/kg per day) and January and December 2010 (60 mg/kg per day) were reviewed. Patients with cystic …
Clinical Issues Surrounding Once-Daily Aminoglycoside Dosing In Children, Chad A. Knoderer, Julie A. Everett, William F. Buss
Clinical Issues Surrounding Once-Daily Aminoglycoside Dosing In Children, Chad A. Knoderer, Julie A. Everett, William F. Buss
Chad A. Knoderer
Aminoglycoside antibiotics are first-line treatment for many infectious diseases in the pediatric population and are effective in adults. The traditional dosing interval in children is every 8–12 hours. Studies in adults reported equivalent efficacy and equal or less toxicity with once-daily regimens. Despite many studies in the adult population, this approach has yet to become standard practice in most pediatric hospitals. Reasons for lack of acceptance of this strategy in children include rapid aminoglycoside clearance, unknown duration of postantibiotic effect, safety concerns, and limited clinical and efficacy data.

Survey Of Congenital Heart Surgeons’ Preferences For Antimicrobial Prophylaxis For Pediatric Cardiac Surgery Patients, Chad A. Knoderer, Emily M. Anderson, Elaine G. Cox
Chad A. Knoderer
Patients with congenital heart defects are a unique population with generally immature immune systems. Fragility in the postoperative period may contribute to surgical site infections (SSIs), a life threatening complication for this population. The need for postoperative antimicrobial prophylaxis for these patients is a standard of care that is indisputable. When choosing an antimicrobial regimen for surgical prophylaxis, consideration should be given to balancing the prevention of nosocomial infections, avoiding emergence of bacterial resistance, and minimizing drug toxicities and cost.

Chad A. Knoderer
We report two cases of children with severe cardiomyopathy requiring treatment with ventricular assist devices who developed acute kidney injury and were treated with fenoldopam. Therapy with fenoldopam appeared successful in one case in that renal replacement therapy was avoided with improvement in urine output and renal function. These are the first reported cases of fenoldopam use in children with acute kidney injury receiving mechanical circulatory support.
