During all valvuloplasty interventions antibiotics (e.g., cefuroxime, I, 5 g, i.v.) are administered. Patients allergic to penicillin should receive vancomycin I g intravenously. Most physicians perform transcatheter valvuloplasty in the fasting state under mild sedation, Substances that are frequently used are meperidine, promethazine, and chlorpromazine, given intramuscularly or intermittent doses of midazolam (0.05 to 0.1 mg/kg, i.v.) and/or fentanyl (0.5 to 1.0 Lig/kg, i.v.). Some operators also apply ketamine or general anesthesia for all interventional cases.

Chlorpromazine increases the respiratory-depressant effects of meperidine, as do tricyclic antidepressants this is not true of diazepam. Concurrent administration of drugs such as promethazine or chlorpromazine also may greatly enhance meperidine-induced sedation without slowing clearance of the drug. Treatment with phenobar-bital or phenytoin increases systemic clearance and decreases oral bioavailability of meperidine this is associated with an elevation of the concentration of normeperidine in plasma. As with morphine, concomitant administration of an amphetamine has been reported to enhance the analgesic effects of meperidine and its congeners while counteracting sedation.
