Percutaneus nephrolithotripsy bleeding in the spinal anesthesia versus general anesthesia

Percutaneus nephrolithotrips is commonly used for the removal of stones. This procedure can be performed under general or spinal anesthesia. In this study we evaluated amount of Bleeding and transfusion needs between two mentioned anesthesia routes. Methods and materials: A total of 80 ASA I-II patients undergoing PCNL were randomly llocated to receive spinal anesthesia (3 ml bupivacain % 0. 5) or general anesthesia which was induced with Thiopentone and maintained with propofol. Estimated blood loss and transfusion rates، postoperative pain (scored from 0 to 10 on a visual analog scale)، in two groups were recorded separately then collected data were analyzed by SPSS13 software. Mean blood loss was 262±113. 8 ml & 148. 1±55. 8 ml in general & spinal group، respectively. There is meaningful difference between two groups (p<0. 001). Rate of transfusion was 7. 5 % in general group & no one in spinal group. The spinal group had better patient satisfaction and lower pain scores (p<0. 001). Post operative pain after 1 hr (VAS) was 4. 2± 1. 0. 1 & 2. 3± 0. 9 in general group & in spinal group respectively. Spinal anesthesia decreased blood loss versus general anesthesia up to 50%، and had less postoperative pain score and is an attractive alternative to general anesthesia in these patients
