Bloqueio dos ramos ventrais das raízes nervosas espinhais toracolombares com associação de Ropivacaína e Hialuronidase em cadela submetida à mastectomia e ovariohisterectomia

Abstract

As a way of deepening the veterinarian's knowledge, the Mandatory Supervised Internship (ESO) is offered in the eleventh period as a means of interaction and experience for the student with the routine and the most common casuistry of the professional in action and relating to what was learned during the subsequent five year course. This course completion work includes a supervised internship report, conducted at the Animalis Clinic - Surgery and Veterinary Clinic (Recife, PE) and a case report of a procedure performed at the site, both focusing on Veterinary Anesthesiology. The ESO comprised the period from March 12 to May 27, 2019, totaling 420 hours in which 39 patients were attended to perform anesthetic procedures. Among the activities described are the results of several important anesthetic topics, such as the most frequently attended systems or specialties, the most commonly used blockages and pharmacological associations, the most used drugs for pre-anesthetic medication (MPA) protocols, among others. In the selected report, whose title is: "Blockage of the ventral branches of thoracolumbar spinal nerve roots with association of Ropivacaine and Hyaluronidase in a dog submitted to mastectomy and ovariohysterectomy", a Maltese dog was admitted for a right unilateral mastectomy and ovariohysterectomy. The anesthetic protocol selected was the blockade of the innervation of the transverse abdominal plane without the use of ultrasound, associating hyaluronidase with ropivacaine so that the drug obtained a greater reach and raised the potency of the local anesthetic in the tissues. The selected protocol was effective and shows that the blockade of the region can be performed with the drugs listed without guided ultrasonography.
