Resumo(s)
A terapia hiperbárica é uma modalidade terapêutica onde o doente beneficia do aumento da pressão atmosférica para melhorar a distribuição e o aproveitamento do oxigénio (O2) pelos tecidos corporais. Para tal, é necessário recorrer-se a câmaras capazes de elevar a pressão atmosférica no seu interior, aumentando opcionalmente a concentração de O2 inalada pelo doente. Se a concentração inalada de O2 for aumentada através do fornecimento de O2 a 100%, denomina-se de Oxigenoterapia Hiperbárica; mas se a concentração inalada de O2 for igual à pressão atmosférica, denomina-se de Terapia com Ar Hiperbárico. A terapêutica hiperbárica é ainda incipiente na Medicina Veterinária, apesar das suas conhecidas vantagens na Medicina Humana. O presente trabalho procura explicar um pouco sobre como funciona a Terapia Hiperbárica em pequenos animais, considerando os seus princípios físicos funcionais, indicações e contraindicações, ilustrando no final com o relato de um caso clínico de um canídeo, fêmea, 9 anos de idade, com diagnóstico diferencial primário de isquémica cerebral difusa, sujeita a terapêutica médica e hiperbárica. A medicina hiperbárica é uma modalidade terapêutica promissora com indicação para uma grande variedade de doenças mas ainda carece de mais estudos para que possa ser melhor entendida.
ABSTRACT - The hyperbaric medicine is a therapy modality where the patient benefits from the increase of the atmospheric pressure to improve the distribution and utilization of the oxygen (O2) by the body tissues. For this, it is necessary to resort to special chambers, capable of raising the atmospheric pressure inside itself, optionally increasing the O2 concentration inhaled by the patient. If the concentration of inhaled oxygen increases by the supply of O2 on 100%, it is called Hyperbaric Oxygen Therapy, if the concentration of O2 inhaled is equal to the atmosphere, it is called Hyperbaric Air Therapy. The hyperbaric medicine is still insipient in Veterinary Medicine, despite its known advantages in Human Medicine. This work seeks to explain a little how the Hyperbaric Therapy works in small animals, considering its functional physical principles, indications and contraindications. For this, it illustrates the story of a clinical case, a 9-year-old female canine with primary differential diagnosis of defuse cerebral ischemic, subject to medical and hyperbaric therapy. Hyperbaric medicine is a promising therapeutic modality, applicable in the veterinary clinical routine, with an indication for a wide variety of diseases, but which still requires further studies in the veterinary medicine.
