General anesthesia such as subarachnoid anesthesia, represent alternatives for patients scheduled for an open cholecystectomy intervention. The second, being a cost-effective option (p<0.001). Cost studies on regional anesthesia for this procedure in our region are relatively inexistent. It is proposed to generate evidence which allows self decision making, in patients who meet criteria for inclusion in application of the technique in discussion. Objectives: To appraise subarachnoid anesthesia for open cholecystectomy as a cost-effective option compared to general anesthesia in patients between 20 and 70 years of age. Methods: Two types of studies are proposed: a) a descriptive prospective series of cases, both gender type of study, with surgical indication for open cholecystectomy, which satisfy all of the criteria for inclusion to subarachnoid anesthesia or general anesthesthesia, with patients between 20 and 70 years of age. b) an analysis of cost-effectiveness in which the two anesthetic techniques used in open cholecystectomy will be compared. Results: 73 patients were included, with a distribution of 7 females for every male, with an average age of 51.2 years, for the group under general anesthesia, with an average BMI of 26.2 kg/m², and 46.4 years of age for the group under subarachnoid anesthesia with average BMI of 25.7 kg/m². There were no important hemodynamic alterations. Both anesthetic techniques were effective. Costs per case showed that subarachnoid anesthesia is 2.5 times more economical for the same.surgical procedure performed under general anesthesia (p<0.001). Conclusions: Subarachnoid anesthesia for open cholecystectomy is a cost- effective alternative which can be reproduced in any area of the Colombian geography.
