AbstractA blind, placebo-controlled clinical trial was performed to evaluate the postoperative analgesic effect of preoperative infiltration of the incision site with bupivacaine in dogs undergoing celiotomy. Sixty dogs were randomly allocated into four groups: preoperative bupivacaine, postoperative bupivacaine, preoperative saline, and postoperative saline. All dogs were premedicated with acepromazine and meperidine; then they were anesthetized with thiopentone and isoflurane. Each group received either bupivacaine or normal saline before midline incision or just before skin closure. After surgery, pain scores were assigned using a numerical rating scale. Preoperative bupivacaine was associated with significantly lower pain scores and a significantly lower need for opioid administration. The authors conclude that a preoperative incisional block with bupivacaine seems to be a useful adjunct for controlling pain after celiotomy in dogs.
