Early experience with continuous positive airway pressure (CPAP) in 5 horses — a case series.

Abstract: This case series is the first report of the use of CPAP (continuous positive airway pressure) ventilation in adult horses. Two horses and 3 ponies anesthetized for orthopedic procedures in lateral recumbency received 10 cm H(2)O CPAP. During anesthesia, arterial oxygen partial pressure tended to increase and arterial carbon dioxide pressure tended to increase despite increased minute ventilation index. The measured cardiovascular parameters were within physiologic limits. Cette série de cas est le premier rapport sur l’utilisation de la ventilation spontanée en pression positive continue (VSPPC) chez les chevaux adultes. Deux chevaux et 3 poneys anesthésiés pour des interventions orthopédiques en décubitus latéral ont reçu une VSPPC de 10 cm HO. Durant l’anesthésie, la pression partielle de l’oxygène dans le sang artériel a eu tendance à augmenter et la pression du gaz carbonique dans le sang artériel a eu tendance à augmenter malgré un indice de débit volume-accru. Les paramètres cardiovasculaires mesurés se situaient dans les limites physiologiques. (Traduit par Isabelle Vallières)

This research studies the application of continuous positive airway pressure (CPAP) ventilation for adult horses undergoing orthopedic procedures. The finding highlights that despite CPAP causing arterial oxygen and carbon dioxide pressure to increase, all measured cardiovascular parameters remained within safe physiological limits.

Introduction of CPAP in Veterinary Medicine

  • This study represents a pioneering effort in veterinary medicine as it puts forward the first recorded use of continuous positive airway pressure (CPAP) on adult horses.
  • CPAP is a mode of ventilation that’s common in human medicine, particularly in the management of conditions like sleep apnea. Its application in veterinary practice, until this study, was unfamiliar.

Testing and Application of CPAP

  • The procedure was carried out on five horses – two adult horses and three ponies- all of which were anesthetized for orthopedic procedures.
  • The horses were positioned in lateral recumbency (lying on their sides) and received 10 cm H(2)O of CPAP.
  • No adverse effects from the introduced CPAP were reported for the five tested horses. The horses’ cardiovascular parameters remained within the physiological limits considered safe.

Effects of CPAP on Horses

  • The arterial oxygen partial pressure of the horses tended to rise during the anesthesia. This response can be attributed to the constant airway pressure introduced by the CPAP leading to improved gas exchange.
  • The arterial carbon dioxide pressure of the horses also trended upward, in spite of the increased minute ventilation index. This could be related to an increase in dead space ventilation or altered perfusion patterns during anesthesia.

Future Considerations for CPAP Use in Veterinary Medicine

  • The study opens up new prospects for the adoption of CPAP in veterinary medicine, specifically for procedures requiring anesthesia where maintaining gas exchange is critical.
  • However, the rise in arterial carbon dioxide pressure despite increased ventilation indicates the need for future research and optimization of CPAP use during anesthesia in horses.
