Abstract
Background: Epidural  analgesia is of  great importance in surgical field for postoperative analgesia. Epidural analgesia is a very good technique for post operative analgesia. It is quicker acting and more efficient than any other  analgesic technique.Most commonly used local anaesthetics are Ropivacaine and Bupivacaine. Material and method: Eighty two patients  were selected under American Society of Anaesthesiologist grade 1 and 2 . All the patients were divided into two groups of forty one each. Group RD receivedRopivacaine 15 ml of 0.75 %  withDexmeditomidine  and Group RF recievedRopivacaine with Fentanyl 1 mcg /kg epiduraly. Haemodynamic parameters like oxygen saturation, heart rate, time of onset of analgesia upto dermatome level T10 and duration of analgesia, motor blockade and parameters of sedation scores were observed and compared . At the end of the study all the data were analyzed using independent sample t test, ANOVA test, Chi square test. Results: The onset of analgesia at T10 dermatomal level was significantly earlier in the RD group (6.68±0.47) as compared to the RF group (9.52±0.58) P<0.05. Conclusion: When given epiduraly as a post operative analgesia, dexmeditomidine as an adjuvant provide stable cardio respiratory  parameters, duration of analgesia is long lasting, number of rescue analgesia  required was less or nil in comparison to fentanyl used  as an adjuvant to ropivacaine in epidural analgesia postoperatively.
