Effects of Different Routes of Local Anesthetic Administration in Epidural Anesthesia for Transurethral Resection of the Prostate - Abstract
The aim of this study is to assess the effects of different routes of local anesthetic administration in epidural anesthesia applied to patients undergoing transurethral resection of the prostate (TUR-P).
ASA I-III 60 patients were enrolled in the study. Patients were randomized into the following three groups: in Group N (needle), total volume of local anesthetic (16 mL) was administered through the Tuohy needle (n=20), in Group C (catheter), local anesthetic was administered through the epidural catheter (n=20) and in Group N/C (needle/catheter), local anesthetic was administered through both the needle (8mL) and the catheter (8mL) (n=20). Hemodynamic parameters (MAP, HR), times to reach sensory block T10 (block levels), side effects, patient and surgeon satisfaction were evaluated.
In group C, the patients were hemodynamically more stable at the time of surgery compared to the other two groups (p <0.05). Times to reach sufficient block level were similar in all three groups and side effects were neglectable. Patient and surgeon satisfaction were high and similar in all groups.
As a result, all three techniques can be used in TUR-P patients undergoing epidural anesthesia; however local anesthetic administration through the epidural catheter seems to be more effective in providing rapid and sufficient block levels and hemodynamic stability.
