TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Evaluation of the cost of propofol used for fast-track in cardiac surgery and its impact on global cost of management for anaesthesia and intensive care.', 'Case-control study, prospective (1998) and retrospective (1994).', 'Twenty patients operated for cardiac surgery in 1998 and scheduled for fast-track anaesthesia. Twenty patients in 1994 matched for different criteria to the patient of 1998.', 'In 1998, all drugs, materials used and X-rays, biochemical assays performed were prospectively collected and their cost calculated. In 1994, similar calculations were done retrospectively. Comparison of duration of mechanical ventilation, hospitalization in intensive care and in the hospital were performed.', 'Cost of anaesthesia was similar in 1994 and 1998 (2,646 FF versus 2,294 FF). Global cost of management was significantly lower in 1998 in comparison to 1994 (5,439 FF versus 8,558 FF). Duration of mechanical ventilation, hospitalization in intensive care and in the hospital were shorter in 1998 than in 1994.'] Does [ The use of propofol increase the cost of the management of patients in heart surgery with extracorporeal circulation ]?
OUTPUT:
