PAIVA, Maria Isabel Sousa; CÁPUA, Maria Luísa de; NADER, Talita Thomaz. Neural therapy as a treatment for neurological sequelae caused by crotalic accident in a domestic feline: Case reportAbstract. Snakebite accidents in domestic animals are frequent events in Brazil and can cause severe clinical manifestations, especially when involving snakes of the Crotalus genus, whose venom exhibits neurotoxic, myotoxic, and anticoagulant effects. Neural therapy consists of the application of low-concentration local anesthetics at specific points on the patient, such as acupuncture points, scars considered interference fields, intravenous and intraperitoneal routes, ganglia, among others, with the aim of restoring cellular repolarization and modulating NMDA (N-methyl-D-aspartate) receptors. These receptors are involved in the regulation of cognition, attention, mood, anxiety, and basic functions such as locomotion and respiration. This paper reports the case of a domestic cat with neurological sequelae following a rattlesnake bite, presenting with paralysis of the facial and hypoglossal nerves, stupor, and prostration. The animal received an esophageal feeding tube and polyvalent antivenom, and 48 hours later underwent Neural Therapy (NT) with 0.7% procaine applied to acupuncture points and in the region of the submandibular lymph node. Twenty-four hours after the first application, significant improvement in responsiveness and motor functions was observed, allowing hospital discharge. After seven days, the swallowing reflex had recovered, enabling removal of the esophageal tube and an additional application targeting facial nerve paralysis. By day 14, the patient had achieved complete clinical recovery. NT showed potential as a complementary approach in the neurological rehabilitation following rattlesnake envenomation, and controlled studies are recommended to evaluate its therapeutic efficacy: Case report.
