Abstract
-
\BACKGROUND: Bupivacaine with fentanyl might be suitable as the spinal anesthesia for performing ambulatory surgery to treat varicose vein.
MATERIAL AND METHOD: Thirty patients who underwent spinal anesthesia for a varicose vein operation were enrolled in this study. They were classified into 2 groups of either fentanyl 25 ug mixed with bupivacaine 4 mg (group FB4) or bupivacaine 8 mg (group B8). We compared the groups for the success of the analgesia, the recovery time from sensory and motor block, the side effects and the postoperative complications.
RESULT: The groups did not differ significantly regarding the success of analgesia (13 of 15 [group FB4], 15 of 15 [group B8]). None of the patients were converted to general anesthesia due to surgical pain. None of the patients required medication for hypotension and/or bradycardia. The operative and nonoperative side effects of motor block (tested for by using a modified Bromage scale) was significantly lower in group FB4 than that in group B8, as checked at 2 hours after spinal anesthesia (p<0.05). Recovery from spinal block was significantly quicker in group FB4 than that in group B8 (p<0.05). The first voluntary micturition time did not differ significantly (6.5 hours v 4.5 hours [p=0.143]) between the groups, but a nelatone catheter was inserted into 2 of the group B8 patients due to dysuria.
CONCLUSION
Adequate intraoperative analgesia and hemodynamic stability and faster mobilization were achieved using bupivacaine 4 mg with fentanyl 25 ug. Low dose spinal anesthesia with fentanyl is suitable for performing ambulatory surgery to treat varicose vein.
