Anesthesia: neonate

pequis

Introduction

  • Compared with many other species, the foal is relatively well developed at birth.
  • The smaller size of the foal compared with the adult means that some anesthetic complications, such as hypotension   Anesthesia: monitoring - cardiac output and blood pressure  and respiratory disturbances, as well as post-anesthetic myoneuropathy   Muscle: myopathy - postanesthetic  , are less of a problem.
  • Some features of very young foals require special attention, such as thermoregulation, energy levels and metabolism, stress and the neonatal cardiovascular and respiratory systems.
  • Neonatal foals are more sensitive to the effects of anesthetic drugs than adults. This is due to the differences between neonatal and adult anatomy and physiology.
  • Problems are enhanced when dealing with premature foals   Reproduction: prematurity / dysmaturity  .
  • Most foals often arrive for surgery with their mother, so steps must be taken to ensure minimal stress to them both when separating them before and re-uniting them after surgery, eg sedate the mare, stable mare out of audible range of the foal, etc.
  • The stress which a foal undergoes during anesthesia can lead to the development of gastric ulceration   Stomach: gastric ulceration  in the post-operative period. Administering H2 agonists orally (starting on the day of surgery) for a few days after surgery to help prevent gastric ulceration.
