High frequency oscillatory ventilation in the Neonatal Intensive Care Unit of San José Hospital, Bogota DC, Colombia

Ventilación de alta frecuencia oscilatoria en la Unidad de Cuidado Intensivo Neonatal del Hospital de San José, Bogotá DC, Colombia

Objective: To describe the experience with high frequency oscillatory ventilation (HFOV) in newborns admitted to the Neonatal Intensive Care Unit of San José Hospital, Bogota DC between May 2012 and May 2014, and report the improvement in the initial 6 hours.
Materials and methods: A retrospective study based on a series of cases, in which an analysis was performed on the demographic data, diagnoses, clinical parameters and ventilators used, as well as the response and outcomes.
Results: A total of 24 neonates, with a mean age of 36.5 (±3.7) weeks, required HFOV. The main diagnosis (15; 62%) was congenital diaphragmatic hernia. Conventional mechanical ventilation was used prior to HFOV in 70% of cases. Before HFOV, all of them had a low oxygen levels by oximetry and the arterial blood gases (n = 16) showed a severe oxygenation disorder, which improved 6 hours after starting on HFOV. The PaO 2 increased by 36+ mm Hg and there was a decrease of 8 points in the oxygenation index (n = 9). The pCO 2 decreased by 11.5 ± 3 mm Hg and the pH increased by.10 ± .35. Inotropic drugs were administered to 79% of the patients. The survival rate was 29% and 100% required complementary oxygen at discharge.
Conclusion: It was observed that HFOV improved the oxygenation disorders and the acidbase balance in the first 6 hours after being started in patients with severe lung diseases. The outcome depends more on the underlying disease suffered by the patient and its complications.
