Comparison The Different Delivery Speeds Of Levobupivacaine And Fentanyl In Spinal Anesthesia

In this study, we aimed to compare the different delivery speeds of alow dose combined solution of levobupivacaine and fentanyl on haemodynamia, sensorial and motor blockade. 60 ASA I-III patients for spinal anesthesia undergoing transuretral resection were randomly assigned into two groups by using the combined solution of 7.5 mg levobupivacaine and 25 µg fentanyl in four seconds in group I and 40 seconds in group II with 22 G spinal needle for spinal anesthesia. Heart rate, noninvasive blood pressure, sensorial and motor blockade status were evaluated both before and after injections on regular intervals. When the sensorial block level reached to T10 dermatome, the operation began. There was no statistically significant difference between patients demographic data, operation time, ASA status. There were difference was noticed between hemodynamic status of the patients between two groups (p>0.05). Changes in sensorial blockade levels were similar in both groups (p>0.05), but motor blockade level was one in Group I, while it was noticed two in Group II and it was statistically significant (p 0.05). In this study it was shown that both of the injection rates of combination of levobupivacaine and fentanyl prove stable hemodynamia, but it was shown that motor blockade regression time was longer in rapid injection group.
