Methods of local blockade with lidocaine in cats submitted to laparoscopic ovariectomy

The aim of this work was to compare three techniques of local blockade, as part of a multimodal protocol in cats submitted to videoassisted ovariectomy (OVH). This study included 38 cats, assigned to four groups (control; incisional block, intraperitoneal block and block of the ovarian arteriovenous complex). Pain was assessed using Analogue Visual Scale, Pain Scale of the UNESP and Composite Multimodal Pains Scale-Feline, prior and after surgery. Anesthetic and analgesic protocols provided adequate post-surgical analgesia in most cats. It is concluded that the intraperitoneal administration of lidocaine may be a useful technique to reduce trans-surgical pain, while the use of incisional infiltration with this medication improves early postoperative pain in videosurgeries.
