Both Extremes of Arterial Carbon Dioxide Pressure and the Magnitude of Fluctuations in Arterial Carbon Dioxide Pressure Are Associated With Severe Intraventricular Hemorrhage in Preterm Infants

Abstract: Both extremes and fluctuations of PaCO2 are associated with severe intraventricular hemorrhage. It may be prudent to avoid extreme hypocapnia and hypercapnia during the period of risk for intraventricular hemorrhage.

“…37,38 Conversely, if the pressure control level is not increased due to worsening lung mechanics and consequent hypoventilation, then the patient can become profoundly hypercarbic, which may increase the risk of developing intraventricular hemorrhage. 39,40 Prolonged ventilation at low inspiratory pressure and low lung volume can also cause atelectrauma and VILI. 41 Recently improved volume monitoring capabilities, lung mechanics measurements, and system alarms can better guide clinicians in ventilator adjustments.…”

“…Mais ainda, os movimentos respiratórios espontâneos dos recém-nascidos que não estão coordenados com aqueles promovidos pelo aparelho também levam a alterações significativas na hemodinâmica cerebral. Do mesmo modo, o processo de ventilação tem mudado ao longo dos anos, de forma a torná-la menos agressiva e a aceitar valores sanguíneos de pCO 2 mais amplos do que os anteriormente aceitos, evitando, assim, tanto a hipocarbia como a hipercarbia mais acentuadas, que, em virtude de reduzirem agudamente o fluxo sanguíneo cerebral, são deletérias ao cérebro em desenvolvimento das crianças pré-termo 23 .…”

“…Nada de bom Maior necessidade de sedação, maior hemorragia intracraniana, piores desfechos a longo prazo A hipocarbia é ruim! Sim Sabemos disso há > 25 anos 43 Devemos ser "extremistas" e usar a hipercarbia para evitar a hipocarbia?…”
