Wide variation in single, daily-dose aminoglycoside pharmacokinetics in patients with burn injuries.

Five to seven mg/kg single, daily-dose aminoglycoside regimens have been recently advocated as effective alternatives to traditional aminoglycoside regimens. The rationale for single, daily-dose aminoglycoside therapy is to produce an optimal ratio between aminoglycoside peak concentrations (Cmax) and pathogen minimal inhibitory concentration to maximize bacterial killing and to produce an aminoglycoside-free period during the 24-hour dosing interval. Single, daily-dose aminoglycoside therapy has not been recommended to date for use in the population of patients with burn injuries.

The impact of practice guidelines on prescribing patterns of nondepolarizing neuromuscular blocking agents.

Guidelines for selecting nondepolarizing neuromuscular blocking agents (NNMBAs) were developed and implemented by an interdisciplinary team for use in our intensive care units. They suggest pancuronium as the drug of choice if the patient does not have renal insufficiency and is hemodynamically stable. If either of these criteria is not met and hepatic function is normal, vecuronium is recommended.

QTc-interval prolongation associated with slow intravenous erythromycin lactobionate infusions in critically ill patients: a prospective evaluation and review of the literature.

Intravenous erythromycin has recently been associated with significant QTc interval prolongation, torsades de pointes, and sudden cardiac death. The prolonged the QTc interval attributed to erythromycin typically is associated with rapid infusion rates in excess of 10 mg/minute. We prospectively assessed the relationship between QTc interval prolongation and erythromycin administration by slow intravenous infusion (mean rate 8.
