Nalbuphine and droperidol in combination for sedation and prevention of nausea and vomiting during intra-carotid BCNU infusion.

A therapeutic regimen is described for sedative, analgesic, and anti-emetic effect in patients receiving intra-arterial carmustine (BCNU) for malignant gliomas. This regimen consists of nalbuphine, 30 mg, i.v., and droperidol, 2.5 mg, i.v., given immediately prior to intra-carotid BCNU infusion. Droperidol, 2.5 mg, i.v., is then administered on four hour intervals for sixteen hours post-procedure. This combination provided excellent effect in nine patients treated for twelve intra-carotid infusions. None of the nine patients experienced vomiting, one experienced mild nausea several hours post-infusion, and non complained of severe pain or discomfort. Thirteen additional patients received diazepam, 10 mg, P.O., prior to the intra-carotid BCNU infusion, with fentanyl, 100 mcg, i.v., and prochlorperazine, 10 mg, i.m. at the onset of infusion. All thirteen patients suffered from severe nausea, vomiting, and orbital pain. The nalbuphine/droperidol combination is thought to provide a superior alternative to the traditional narcotic/pheonothiazine/benzodiazepine combination for carotid BCNU infusion. This combination has theoretical advantages for the patient with intracranial mass lesions by providing analgesia and sedation with minimal potential for respiratory depression and carbon dioxide retention.
