Background and Objectives - It is essential to reduce health care costs without impairing the quality of care. Propofol is associated to faster recovery and it is known that post-anesthesia care unit (PACU) costs are high. The aim of this study was to evaluate the advantages of two anesthesia regimens - propofol continuous infusion or isoflurane - taking into account the cost of both techniques on PACU stay. Methods - Forty seven patients, physical status ASA I, II and III, undergoing laparoscopic cholecystectomy were divided into 2 groups according to the anesthetic agent: G1, conventional propofol continuous infusion (100-150 μg.kg-1.min-1) and G2, isoflurane. All patients were induced with sufentanil (1 μg.kg-1) and propofol (2 mg.kg-1) and were kept in a re-inhalation circuit (2 L.min-1 of fresh gas flow) with 50% N2O in O2, sufentanil (0.01 μg.kg-1.min-1) and atracurium (0.5 mg.kg-1), or pancuronium (0.1 mg.kg-1) for asthma patients. All patients received atropine and neostigmine at the end of the surgery. Prophylactic ondansetron, dipyrone and tenoxican were administered and, when necessary, tramadol and N-butylscopolamine. Costs of anesthetic drugs (COST), total PACU stay (t-PACU), and PACU stay after extubation (t-EXT) were computed for both groups. Results - Costs were significantly lower in the isoflurane group but t-PACU was 26 minutes longer and t-EXT G1<G2, although not statistically significant, t-PACU x t-EXT and t-EXT x COST were significant for G1 only. Therefore, in G1, t-PACU was a function of propofol doses. Conclusions - We concluded that the use of isoflurane as anesthesia maintenance agent for laparoscopic cholecystectomy showed lower drug costs as compared to propofol. However, isoflurane group patients stayed longer in PACU as compared to propofol continuous infusion group.
