Use of bupivacaine infiltrative local block in bitches submitted to ovariohysterectomy by celiotomy or video-assisted surgery by two-portals access

Abstract

This randomized blinded study objected to investigate a local anesthesia (0,5% bupivacaine) in the surgical incision site in dogs underwent to ovariohysterectomy by celiotomy or video-assisted by two-portal. Twenty-eight healthy adults were selected. Dogs were divided into celiotomy control group, celiotomy blocking group (BC), video-assisted control group and blocking video-assisted group (BV). In the BC and BV, bupivacaine was administered SC in the incision line or port sites. Control groups received NaCl 0,9% at the same sites. Three evaluators blinded evaluated postoperative pain, using Melbourne Pain Scale and visual analog scale. The anesthetic infiltrative blockade used was efficient in promoting postoperative comfort in both celiotomy and video assisted OVH.
