Abstract

Background: Intermittent bolus administration increases the extent of neural blockade and decreases unilateral blockade, thereby improving the quality of epidural analgesia in postsurgical pain management. Hence, the present study investigates the “Comparison between epidural Ropivacaine plus morphine intermittent boluses versus continuous infusion for post operative analgesia in lower limb surgery”. Materials and Methods: A total 30 participants who were undergoing elective lower limb surgeries were randomly allocated into two groups, group 1 of 15 participants received intermittent bolus (Group IB) and remaining 15 received continuous infusion (Group CI). The comparison between epidural bolus analgesia vs Intermittent bolus with Ropivacaine 0.1% and Morphine 1mg (total of 50ml) ,6mL bolus given every 60 min vs epidural infusion of 6 mL/h flow of Ropivacaine 0.1%/ml and Morphine 1mg. Results: The age, height, weight, BMI and ASA showed a significant difference between the group CI and group IB, respectively, the P value is 0.001*. The VAS showed a significant difference between the 12th and 24th hr of group CI. Additionally, the systolic and diastolic blood pressure and heart rate does not show any significant between the 12th and 24th hr of group CI. Conclusion: Based on study findings, we conclude Intermittent boluses are similar to continuous infusion of epidural ropivacaine plus morphine for post operative analgesia and produced a faster onset, greater success rate of analgesia.
