In children it is important to prevent perioperative crying, as it causes hyperventilation leading to hypocapnia with possible risk of cerebral vasoconstriction, decreased cerebral blood flow and cerebral ischaemia.
Hypercapnia can cause cerebral vasodilation while hypocapnia causes constriction that can be marked.
Along with respiratory care for the ventilated neonate, ventilation monitoring is of great importance for a good oxygenation avoiding hypercapnia and hypocapnia, both associated with deleterious effects not only on preterm but also on term brain.
Some of the suggested risk factors for the development of CE in DKA are young age, severe acidosis, hypocapnia, elevated blood urea nitrogen (BUN), dehydration, aggressive fluid resuscitation, sodium bicarbonate, and bolus/early insulin administration [15-17].
This study had several limitations: first, we did not perform a measurement of end-tidal CO2 because of limited resources and we did not assess CVMR in hypocapnia condition.
