SummAry – The aim of this study was to analyze hemodynamic changes in hypertensive and normotensive patients undergoing total hip or knee replacement in spinal and general anesthesia. eighty patients who underwent total hip or knee replacement surgery in the period between July 2010 and february 2011 at Sveti duh university hospital were retrospectively evaluated. Seventeen patients underwent the operation in general anesthesia and 63 patients in regional anesthesia. They were allocated into groups of normotensive (n=24) or hypertensive patients (n=56). The anthropolo-gic and hematologic parameters of normotensive and hypertensive patients were compared, as well as their blood pressures immediately before and during the operation. blood pressure immediately before anesthesia induction, the highest and the lowest intraoperative blood pressures were recorded. blood pressure immediately before anesthesia induction was significantly higher in hypertensive patients who underwent the operation in regional anesthesia compared to normotensive patients (158.48 mm hg vs. 144.71 mm hg, P<0.01). The highest intraoperative systolic blood pressure was also significantly higher in hypertensive patients operated on in regional anesthesia compared to normotensive patients (161.20 mm hg vs. 146.76 mm hg, P<0.01). The difference between the hi-ghest and the lowest intraoperative systolic blood pressure was significantly greater in hypertensiv
