Anaesthetists choose daily among wide varieties of neuromuscular blocking drugs and rapidly acting hypnotic agents. This study sought to determine whether definitive, immediate knowledge of drug cost might influence clinician choices, ultimately reducing the cost of anaesthesia care. Faculty anaesthetists, residents in training, and nurse anaesthetists served as subjects in this prospective, sequential, blinded study of prescribing habits. ⋯ Ketamine usage normalized by total anaesthesia duration increased (P < 0.05) following sticker placement. The weekly cost of all drugs inventoried normalized for caseload did not differ during the measurement periods. Immediate cost awareness, implemented simply as price stickers on drug units, had minimal impact on clinicians' drug usage in a tertiary care setting.

Watson's syndrome is an uncommon genetic disorder whose features include mental retardation and pulmonary valvular stenosis. The purpose of this report is to describe one management strategy used successfully to anaesthetize a woman with this disorder who presented for Caesarean section. Epidural anaesthesia using 0.5% bupivacaine without epinephrine in 2-3 ml boluses to a total dose of 15 ml was administered over 30 min. ⋯ Postoperative analgesia was provided using 3 mg epidural morphine. The patient was observed in the intensive care unit for the first postoperative day and experienced an uncomplicated intra- and postoperative course. We conclude that this technique represents a safe and effective method for anaesthetizing patients with this complicated problem for Caesarean section.

We investigated the prophylactic antiemetic effect of added low-dose infusion of propofol in patients exhibiting nausea and vomiting refractory to dexamethasone and serotonin antagonist during non-cisplatin chemotherapy for breast cancer. In a prospective open longitudinal study, 117 patients who had more than five episodes of nausea and vomiting in their first chemotherapy cycle during the first 24 hr completed the study. They received in addition to the usual prophylactic antiemetic regimen a continuous intravenous infusion of 1 mg.kg-1.hr-1 propofol started four hours before chemotherapy and continued up to 24 hr for the two subsequent cycles. ⋯ Patients were more frequently active and had more appetite during the propofol-assisted cycles. No propofol-associated side effects were observed. We conclude that the addition of a subhypnotic infusion of propofol enables better control of nausea and vomiting caused by non-cisplatin chemotherapy in the first 24 hr post-treatment.
