Evaluación de la efectividad analgésica posoperatoria mediante bloqueo del plano transverso del abdomen (bloqueo PTA) en perros sometidos a cirugías del tracto reproductor y tracto gastrointestinal en la Clínica Veterinaria Dr.Pet.

Abstract

The therapeutic objective of local anesthesia (locoregional blocks) is to provide a reversibly blockage of the generation and spread of action potentials of neural systems in a given area. Transverse abdominal plane block (TAP Block) is a local anesthesia technique which is part of a multimodal analgesia protocol. This technique provides analgesia in the abdominal wall in the ventral and lateral area; it includes abdominal skin and subcutaneous tissue, abdominal muscles, parietal peritoneum, and mammary glands. The following undergraduate work seeks to evaluate and compare the analgesic effectiveness during the postoperative period of TAP block and constant rate infusions (CRI) of fentanyl, lidocaine and ketamine (FLK). Pain will be assessed using the University of Melbourne Pain Scale over a period of 12 hours in the postoperative phase in patients undergoing surgeries of the gastrointestinal tract and reproductive system with an abdominal approach. As a result, it is expected that the PTA blocking technique will provide a greater degree of analgesia and a rapid return to the patient's normal physiological functions compared to the constant-rate FLK infusion. With a CRI of FLK, the return to normal physiological functions will be slower due to the side effects of systemic opioid application. An analgesic strategy with a multimodal approach using a PTA block will provide greater clinical efficiency in the recovery of the patient and facilitate its management in the postoperative phase
