This article intends to review literature on high frequency oscillatory ventilation and describe its main clinical applications for children and neonates. Articles from the last 15 years were selected using MedLine and SciElo databases. The following key words were used: high frequency oscillatory ventilation, mechanical ventilation, acute respiratory distress syndrome, children, and new-born. The review describes high frequency oscillatory ventilation in children with acute respiratory distress syndrome, air leak syndrome, and obstructive lung disease. Respiratory distress syndrome, bronchopulmonary dysplasia, intracranial hemorrhage, periventricular leukomalacia, and air leak syndrome were reviewed in neonates. Transition from conventional mechanical ventilation to high frequency ventilation and its adjustments relating to oxygenation, CO2 elimination, chest radiography, suctioning, sedatives and use of neuromuscular blocking agents were described. Weaning and complications were also reported. For children, high frequency oscillatory ventilation is a therapeutic option, particularly in acute respiratory distress syndrome, and should be used as early as possible. It may be also useful in the air leak syndrome and obstructive pulmonary disease. Evidence that, in neonates, high frequency oscillatory ventilation is superior to conventional mechanical ventilation is lacking. However there is evidence that better results are only achieved with this ventilatory mode to manage the air leak syndrome.

OBJECTIVES: To evaluate risks for persistent pulmonary hypertension in the newborn, confirmed by echocardiography, associated with cesarean deliveries and other factors. METHODS: Cohort of all deliveries >36 weeks within a period of 23 months. A nested case-control study was performed in a subset of the cohort, involving newborns admitted into neonatal intensive care unit with diagnosis of persistent pulmonary hypertension matched with normal controls, with application of questionnaires to mothers to identify risks. Logistic regression was used to calculate odds ratios. RESULTS: From 9452 newborns, 8388 (88.7%) were delivered by cesarean and 1064 (11.3%) by vaginal delivery. Questionnaires were applied to 173 mothers. Infants from cesareans had a fivefold increased risk of persistent pulmonary hypertension of the newborn: 42 (0.5%) versus 1 case (0.09%) in the vaginal group (OR 5.32, p=0.027). No interactions were found between smoking, parity, arterial hypertension and labor before cesarean section and persistent pulmonary hypertension of the newborn. First minute Apgar score <7 and maternal diabetes were related to increased risk. CONCLUSION: Reducing cesarean deliveries could prevent many cases of serious persistent pulmonary hypertension of the newborn.

The purpose of this paper was to carry out a review of literature on the history and current stage of the knowledge of systemic analgesia in neonatology and the factors influencing its use. A search for scientific articles was made in the MEDLINE, SciELO and LILACS databases using the keywords: analgesia, systemic analgesics, pain, neonatology, newborn, intensive care units and neonatal intensive care units. Additional research was made on dissertations and thesis databanks as well as text books. Literature consulted disclosed that, in general, analgesia is not a routine practice in neonatal intensive care units, despite the numerous studies demonstrating its importance. Although pain relief is a basic principle of medicine, involving ethic and humanitarian issues and despite the current availability of a number of practical guidelines and consensus regarding pain management in newborns at risk, findings of the present study fall far short of current recommendations. Urgent intervention is required to redress this situation.
