 Anesthetized patients with a high ICP should be ventilated to maintain normocapnia.

 Although hyperventilation has been recommended in the past, it is now recommended that normocapnia should be maintained.

 In small foals, heavy sedation/anesthesia can be obtained using midazolam and propofol infusions. Dexmedetomidine infusion might also help to reduce drug requirements and stabilize ICP.In any case, normocapnia should be maintained, but this may be difficult to achieve in a sedated foal, and it may be necessary to induce and maintain anesthesia to allow the foal to be intubated and ventilated.Neonatal foals may have reduced ability to metabolize drugs so signs of deepening sedation indicate a need to reduce the amount of drug administered.Care should be directed towards life support during long‐term sedation, including provision of nutrition.

 The ability to use intermittent positive‐pressure ventilation (IPPV) to hyperventilate horses and maintain PaCO2 will be considerably affected by the presence of ventilation/perfusion mismatch and the time required to maintain a horse in recumbency. This technique is probably not feasible in adult horses.
