Abstract

The present study was aimed to evaluate the comparative efficacies of incisional local anesthetics following rumenotomy in Black Bengal goats. Goats (N=40) were randomly allocated equally into LID, LID+A, BUP and SAL groups. After overnight fasting, goats were injected with 0.5 mg kg-1 meloxicam subcutaneously and 1 mg kg-1 diazepam intramuscularly. Left paravertebral analgesia were achieved in goats of aforementioned groups using 5 ml of 2% lidocaine, 2% lidocaine plus adrenaline, 0.5% bupivacaine and 0.9% NaCl. The rumenotomy was performed and before closing the skin, 2% lidocaine (7 mg kg-1), 2% lidocaine plus adrenaline (7 mg kg-1) and 0.5% bupivacaine (2.5 mg kg-1) were infiltrated incisionally in goats of LID, LID+A, BUP groups, respectively. However, the goats of SAL group were infiltrated incisionally with 5 ml of 0.9% saline. Pain and wound tenderness were evaluated by pricking and manual pressing around the wound whereas sedation was assessed by observing behavioral manifestations using dynamic interactive visual analogue scale before premedication, 0.5, 1, 2, 4, 8 and 22 hours after surgery. Data were analyzed using one-way ANOVA followed by Bonferroni test. Goats of LID and LID+A groups showed moderately less pain up to 4 hours. BUP groups exhibited the least pain at 4 and 8 hours. LID group measured lower (P
