This study has shown that Sweden has a low immediate ICU mortality, similar in adult ICU and PICU. Patients discharged alive from an ICU had a 20-fold increased mortality risk, compared with a control cohort for the 5-year period. Less than half of the paediatric patients admitted for intensive care in Sweden were cared for in a PICU. Studies are needed to evaluate whether a centralization of paediatric intensive care in Sweden would be beneficial to the paediatric population.

We conclude that neonates and infants are able to regulate cardiac output by changing the stroke volume to a greater extent than presumed, at least when cardiac output is influenced by changes in the mean airway pressure.

Fifteen neonates and infants were investigated during pressure controlled ventilation (PCV) and pressure support ventilation (PSV) on a Servo 300 ventilator. Changes in cardiac output (aortic mean blood flow velocity) were assessed with the Doppler technique. During PSV cardiac output increased by 16% (P < 0.01) compared with PCV with equal ventilation. Mean airway pressure decreased significantly during PSV compared with PCV, which may explain the increased cardiac output. During PSV, when inspiratory/expiratory (I:E) relations are dependent on the patient, we found a lower I:E ratio compared with PCV. It can be assumed that at least part of the decreased mean airway pressure is caused by the lower I:E ratio. As the heart rate was unchanged, the variations in cardiac output were caused by alterations in stroke volume. It is concluded that a patient triggered mode should be preferred providing that the neonate/infant has the ability to elicit the ventilator's triggering system.
