- Arterial Blood Gas Interpretation
- Anesthetic Considerations for the Draft Horse
- Equine Anesthesia: Selecting a Protocol
Anesthetic Management of the Equine Dystocia
This segment reviews the anesthetic considerations for the periparturient mare. This presentation will provide the participant with a review of physiologic changes with pregnancy and with fetal development. This course will also provide the participant with the pharmacologic differences and considerations between the pregnant mare and the non-pregnant animal and will provide the basic understanding needed to develop an appropriate anesthetic plan for these cases. This presentation will also provide management strategies for intraoperative complications including severe V/Q mismatching, hypotension, and ventilatory control.
Anesthetic Management of an ASA III Case
This segment discusses an equine colic case example in the perspective of managing the severe cardiopulmonary complications in unstable patients. The presentation provides a systematic approach to generating a problem list and differential diagnoses for the common anesthetic complications. In discussing the cardiopulmonary compromise in this patient population, the participant will also review V/Q ratios, the clinical implications and management strategies of V/Q mismatching, and a systematic approach to the management of hypotension.
Arterial Blood Gas Interpretation
This primary objective of this segment is to review the fundamental concepts of acid-base status and pulmonary function in the horse and provide practice to improve the proficiency of blood gas interpretation. The participant will review the different oxygenation indices (including the a/A ratio, A-a gradient and P/F ratio as a marker of gas exchange efficiency in the lung. The course also reviews the basics of the acid-base physiology and how the blood gas parameters describe define the acid-base status of the patient. The participant will then have eight practice examples that walks them through a systematic approach to interpreting arterial blood gases.
Anesthetic Considerations for the Draft Horse
This segment reviews the unique considerations for draft horse anesthesia. This program will provide the participant a review of cardiac output physiology in the context of peripheral perfusion and oxygen delivery. This segment will also provide the participant with a better understanding of allometric scaling and how the increased body size of draft horses will affect the pharmacodynamics and pharmacokinetics of the anesthetic protocol selections. It will also provide multiple strategies for managing hypoxemia and hypotension in the intraoperative environment which could be applicable to any anesthetic case. Lastly, by using an upper airway surgery example, this segment will also provide the participant with multiple considerations and management strategies for this specific type of procedure.
Equine Anesthesia: Selecting a Protocol
The primary learning objective of this segment is to improve the participant's ability to develop an anesthetic plan for a typical equine case. By using an example orthopedic case, the participant will learn how to identify the important physical exam findings and medical history that will affect the anesthetic protocol, compound them into a problem list, and how they will predispose different cases to the common anesthetic complications. The segment will review most common anesthetic protocols and the pros and cons of varying protocol decisions.
