Randomized trial of continuous positive airways pressure to prevent reventilation in preterm infants.
ABSTRACT A prospective randomized controlled trial was performed comparing the use of a short period (24 hr) of postextubation nasal continuous positive airways pressure (CPAP) with direct extubation into headbox oxygen on the outcome of the need for reintubation within 7 days of initial extubation. Infants at less than 32 weeks of gestation who had received mechanical ventilation in the first 28 postnatal days and were being extubated for the first time were recruited. Ninety-seven babies were entered into the study (48 CPAP and 49 headbox oxygen). Twenty-four (49%) babies in the headbox group were reventilated within a week, compared to 16 (33%) in the CPAP group (P=0.17). By 14 days after initial extubation, 25 babies (51%) in the headbox group and 23 (48%) in the CPAP group required reventilation (P=0.9). There was a trend toward babies in the CPAP group requiring fewer reintubations (median, 2; range, 1-6) compared to those in the headbox group (median, 3; range, 1-7) (P=0.063). There was no significant difference between groups with respect to total number of days of ventilation (headbox median, 4; range, 1-24; CPAP median, 2; range, 1-20). In conclusion, this study showed that a short period of nasal CPAP is not associated with a reduction in reventilation.

ABSTRACT: Mechanical ventilation is associated with significant short- and long-term morbidity in small preterm infants. Continuous positive airway pressure applied through nasal prongs is an effective, less-invasive method to improve gas exchange and reduce apnea in these infants. A large number of studies have evaluated the possibility of reducing the need or duration of mechanical ventilation by early use of nasal continuous positive airway pressure shortly after birth and by applying it after extubation. Although results of these trials have not been consistent, most of the evidence suggests that nasal continuous positive airway pressure is a viable alternative to mechanical ventilation in many preterm infants and that its use after extubation contributes to maintain better lung function and reduces apnea. Despite this, there is no evidence that these beneficial short-term effects translate into lower rates of long-term morbidity such as bronchopulmonary dysplasia and neurologic sequelae or mortality rates.Journal of Perinatology 06/2006; 26 Suppl 1:S33-7; discussion S43-5. · 2.25 Impact Factor

ABSTRACT: Continuous positive airway pressure (CPAP) is widely used in neonatal units both as a primary mode of respiratory support and following extubation from mechanical ventilation. In this review, the evidence for CPAP use particularly in prematurely born infants is considered. Studies comparing methods of CPAP generation have yielded conflicting results, but meta-analysis of randomised trials has demonstrated that delivering CPAP via short nasal prongs is most effective in preventing re-intubation. At present, there is insufficient evidence to establish the safety or efficacy of high flow nasal cannulae for prematurely born infants. Observational studies highlighted that early CPAP use rather than intubation and ventilation was associated with a lower incidence of bronchopulmonary dysplasia (BPD), but this has not been confirmed in three large randomised trials. Meta-analysis of the results of randomised trials has demonstrated that use of CPAP reduces extubation failure, particularly if a CPAP level of 5 cm H2O or more is used. Nasal injury can occur and is related to the length of time CPAP is used; weaning CPAP by pressure rather than by "time-cycling" reduces the weaning time and may reduce BPD. In conclusion, further studies are required to identify the optimum mode of CPAP generation and it is important that prematurely born infants are weaned from CPAP as soon as possible.European Journal of Pediatrics 12/2011; 171(10):1441-8. · 1.98 Impact Factor

ABSTRACT: The use of mechanical ventilation for the treatment of respiratory distress syndrome (RDS) in low birth weight infants may cause barotrauma, volutrauma, and chronic lung disease. Different continuous positive airway pressure (CPAP) delivery systems exist, each with its own practical and clinical advantages and disadvantages. CPAP can be used as either a primary or an adjunctive respiratory support for RDS. Research demonstrates that CPAP decreases the incidence of respiratory failure after extubation. Clinical trials indicate that the optimal management of neonatal RDS consists of early surfactant treatment followed quickly by extubation and stabilization on CPAP. Early surfactant treatment combined with CPAP reduces the need for mechanical ventilation, compared to later surfactant treatment. Evidence suggests a synergistic effect between early surfactant administration and rapid extubation to nasal CPAP.The journal of pediatric pharmacology and therapeutics : JPPT : the official journal of PPAG. 07/2006; 11(3):145-52.
