Gamma-hydroxybutyrate: is it a feasible alternative to midazolam in long-term mechanically ventilated children?

Benzodiazepines like midazolam are commonly used for long-term sedation of critically ill children requiring mechanical ventilation. Tolerance to midazolam may occur in these patients resulting in a ceiling effect with insufficient or missing sedative response to increases of midazolam infusion or bolus application. The aim of this study was to evaluate the feasibility of a drug rotation protocol replacing continuous infusion of midazolam with gamma-hydroxybutyrate (GHB) to counteract midazolam tolerance.
