Abstract: Background: Popliteal nerve block used for below knee surgery in old age group people who are more vulnerable for hemodynamic disturbances, is beneficial with reduced morbidity and mortality. Rapid post operative mobilization and lack of post dural puncture headache are mainly useful in day care operations.
Objectives: To compare the sensory and motor blockade onset of 0.5% Levobupivacaine and 0.5% Ropivacaine.
To compare the post-operative analgesia duration of 0.5% Levobupivacaine with 0.5% Ropivacaine.
Methods: After institutional ethical committee clearance and informed consent from the patients, 60 patients of either sex, aged 18-70 years, belonging to ASA 1 and 2 were enrolled in the study. Subsequently the patients were allocated into the group (L) or the group (R) in a random manner by sealed envelope method with 30 patients in each group (n=30).
Under aseptic precautions, ultrasound guided popliteal nerve block was performed with 20 ml of either 0.5% Levobupivacaine with Dexmedetomidine or 0.5% Ropivacaine with Dexmedetomidine. Group L: Received 19.5 ml of 0.5% Levobupivacaine + 0.5 ml (25mcg) of Inj. Dexmedetomidine making total volume of 20ml.
Group R: Received 19.5 ml of 0.5% Ropivacaine + 0.5 ml (25 mcg) of Inj. Dexmedetomidine making total volume of 20ml.
Results: No statistical significant difference in view of action onset, block duration and block quality in the two groups. No adverse effects or hemodynamic disturbances in any of the groups. 0.5% Levobupivacaine and 0.5% Ropivacaine both had satisfactory and comparable sensory and motor block in our study.
Conclusion: As there was adequate post operative pain relief and steady hemodynamic parameters perceived in this present study, it can be determined that Popliteal nerve block can be the best alternate anesthetic practice for below knee surgeries and both the drugs can be used for significant block.
