title: [The use of glycopeptides in intensive care and anaesthesia].
abstract: With the objective of clarifying the modes of using glycopeptides in intensive care, a survey with a declared intention was performed in June 2001, in the form of a postal questionnaire; it was possible to exploit 742 answers. Analysis of the results showed that 15% of the doctors completing the questionnaire had not employed glycopeptides within the past six months. Preference was given to vancomycin, and 65% of practitioners prescribed this drug only, while 1% of them only prescribed teicoplanin. For vancomycin, a central route is used in 9 out of 10 cases, with a preference for continuous infusion (69% versus 48%). A loading dose is prescribed in 70% of continuous infusions (> or = 15 mg.kg-1 in 69% of cases), and in 19% of intermittent infusions (> or = 15 mg.kg-1 in 90% of cases). The mean vancomycin dosage is 30 mg.kg-1.d-1; in the case of intermittent administration this involves two (51%), three (17%) or four (27%) injections per day. The target concentrations are residual serum vancomycin levels of between 13.5 and 23.6 mg.L-1 with intermittent administration or plateau levels of 18.3 to 29.4 mg.L-1 with continuous infusion. Teicoplanin is administered intravenously (92%) and/or via the i.m. route (34%). The mean dosage is < 10 mg.kg-1.d-1 in seven out of ten cases. A loading dose is administered every 12 hours at the same dosage in 77% of cases (< or = 3 injections for 65% of prescribers). The residual teicoplanin concentrations sought are between 14.3 and 25 mg.L-1. Monitoring of serum levels is ensured at least once a week in 97% of cases with vancomycin and 66% of cases with teicoplanin. In conclusion, is seems that the methods of using glycopeptides vary considerably. The great heterogeneity of practices suggests a lack of compliance by prescribing practitioners with current recommendations. It also seems that a precise definition of the target plasma levels to be achieved in different indications is necessary.
