COMPARISION OF INTRAOPERATIVE AND PREOPERATIVE HEMODYNAMIC PARAMETERS AND QT CHANGES IN ECG IN PATIENTS UNDERGOING TRANSURETHRAL RESECTION OF THE PROSTATE UNDER SPINAL ANESTHESIA Onur

OBJECTIVE: In our study we aimed to compare intraoperative hemodynamic changes and changes in QT interval with preoperative values in patients undergoing transurethral resection of the prostate (TUR-P) under spinal anesthesia. MATERIAL AND METHODS: The study comprised of 45 patients, between the ages of 40 to 65 and ASA I-II who were planned to undergo transurethral resection of the prostate. The patients were randomly divided into 3 groups. %0.9 NaCl to group I, gelatin to group II, and to group III hydroxyethyl starch were intravenously injected via using 18 gauge intravenous catheter. Hemodynamic parameters were recorded as 5-minute intervals in preoperative period and also during the operation. QT values were recorded in 5, 15, 30, 60 minutes, before, during and after the operation. RESULTS: There was no significant hemodynamic differences between the groups whereas in Group I, QT interval, between the preoperative and postoperative period were significantly different. Also we compared preoperative values and postoperative values of post-op 5min and 10min and found significant difference and increase. In Group II, preoperative and postoperative QT intervals were significantly different and the measurements are found to be increased. In Group III the difference between preoperative and postoperative 15min and 20min values were significant and the measurements are found to be increased. In Group III, there was significant difference between the values taken in 5 min and other times and the measurements are found to be increased. CONCLUSIONS: In view of prolonging on intraoperative and postoperative QT interval on patients that have TUR-P operation; more care should be taken in patients who are planned TUR-P operation, who have coronary heart disease and have pre-operative acquired or congenital prolonged QT interval
