Filter by:Lung recruitability is essential for optimal Positive end-expiratory pressure (PEEP) selection in ARDS patients. It is defined as the potential for the non aerated or poorly aerated lung mass to become aerated due to the increase in airway pressure. PEEP contributes to lung recruitment mostly by maintaining some amount of the end-inspiratory recruitment at the end of expiration. PEEP also stabilizes patency of the small airways and minimizes the repeated opening and closing of them during the breathing cycle, which is implicated in a further lung inflammation. The gold-standard method for assessing lung recruitability is lung CT scan. For economic and feasibility this technique cannot be used in routine. Therefore, techniques that can be used at the bedside to measure lung recruitability are very well known. The measurement of recruited lung volume (Vrec) by using pressure-volume curve generated by the ventilator is another reference method to approach lung recruitment. It can be done at the bedside. Chest-X-Ray (CXR) is an interesting option as done in routine in this setting. Furthermore, it allows quantifying aeration thanks numerical image processing and a regional approach. In a preliminary one-center study we found a significant negative correlation between the amount of Vrec and the reduction in lung density measured by digital CXR between 5 and 15 cm H2O PEEP. In present study we would like to extend this previous result on a larger number of patients in a multicenter investigation.
The objective of this study is to determine whether use of the spontaneous breathing trial allows for earlier successful extubation of very low birth weight (VLBW) infants who are intubated for >48 hours and have not yet been successfully extubated (extubated >7 days).
Nearly forty years ago Berran and coworkers tested an analog oxygen controller to maintain incubator oxygen levels for infants suffering neonatal respiratory disease in order to prevent hyperoxia. There are at least three clinical issues that this technology addresses: the first is avoidance of episodic hyperoxia; the second is decreasing episodic hypoxia; and the third is lowering cumulative oxygen exposure. Clinical trials which have used target SpO2 ranging probably help improve all of these problems, but so far there have been no direct measurements of continuous arterial oxygen levels, nor clinical studies which establish the degree to which improving control over blood oxygen saturation decreases the cumulative amount of oxygen exposure. This study will address the later and is an important step in the process of incorporating closed-loop oxygen control technology as a routine standard of neonatal respiratory care. OBJECTIVES: PART 1: Test and modify the instruction set for the computerized oxygen controller to achieve a goal of less than six (6) operator required interruptions per hour for oxygen saturation deviations outside of study guidelines. PART 2: Perform a within patient cross-over trial of the computerized oxygen controller versus standard of care (the patient's care team adjusts the patient's oxygen level) and evaluate the area under the time curve for oxygen exposure between the two control methods. PART 3:(After successful completion of PART 2) Continuation of the within patient cross-over study with a randomized cross-over sequence. Studies will last 4 to 12 hours divided in two (2) equal time blocks with one cross-over to either automatic or manual control modes. Provision for up to an additional twenty (20) patients to be studied.
To evaluate the feasibility, safety and tolerability of aerosolized lucinactant delivered by nasal continuous positive airway pressure (nCPAP) for the prevention of respiratory distress syndrome (RDS) in premature infants.
Approval of surfactant by the FDA in 1989 for the treatment of Respiratory Distress Syndrome (RDS) in premature infants greatly improved survival rates. Newer surfactants approved by the FDA were more concentrated and had a more rapid onset of action. The overall efficacy of newer surfactants appeared similar until in 2004, Ramanathan and colleagues suggested that a double dose of Curosurf improved survival in infants 25-32 weeks gestational age, compared to infants treated with Survanta, the most commonly used surfactant preparation in the United States. While the data was suggestive, it was not clear that the improvement in survival was reproducible or that Curosurf was responsible for the improved survival rates. The purpose of this study was to investigate the role of Curosurf in improving lung function and survival rates and reducing the complications of prematurity in very premature infants < 30 weeks gestational age at birth.
Administration of steroid to the mother in imminent preterm delivery is a known effective practice to decrease the risk of respiratory distress syndrome and intraventricular haemorrhage in preterm infants if given with a week of the preterm delivery. This randomized clinical trial is performed to test the possibility whether the repeat dose of steroid results in further reduction of these diseases in case the mother is in imminent preterm delivery more than a week after the first antenatal steroid treatment.
Pulmonary inflammation plays an important role in the development of chronic lung disease (CLD) in preterm infants. This inflammation occurs very early in postnatal life. Any therapy that could be beneficial in preventing CLD should be started very early. The investigators' previous double-blind study has shown that early (< 12 hours) postnatal use of intravenous dexamethasone for 4 weeks significantly suppressed pulmonary inflammation and significantly reduced the incidence of CLD. However, the use of dexamethasone was associated with increased incidence of infection and sepsis. Their follow-up study also suggested an increase in the incidence of psychomotor anomalies. As compared to intravenous administration, endotracheal instillation will provide more local anti-inflammatory effects and less systemic side effects. Infants will be eligible for the study if their birth weight (BW) is < 1500 gm and if they had severe respiratory distress syndrome (RDS) requiring mechanical ventilation shortly after birth. After informed consent is obtained, the infant will be randomly assigned depending on the condition of the infant. The primary outcome is the change in cytokines (interleukin-6, 8, 10 and TNF-α) levels in BAL fluid. Chronic lung disease (CLD) was judged at 36 postmenstrual weeks. Infants in the study group (S/B group) received surfactant (Survanta®, Abbott Laboratories, North Chicago, IL; 100 mg or 4 mL/kg/dose) and Budesonide (Pulmicort®, AstraZeneca Pty Ltd., Australia; 0.5 mg or 1mL/kg/dose), while those in the control group (S group) received surfactant (Survanta® Abbott, 100 mg/kg/dose) and saline (1mL/kg).
This multicenter clinical trial tested whether minimal ventilation decreases death or BPD. Infants with birth weight 501g to 1000g and mechanically ventilated before 12 hours were randomly assigned to minimal ventilation (partial pressure of carbon dioxide [PCO(2)] target >52 mm Hg) or routine ventilation (PCO(2) target <48 mm Hg) and a tapered dexamethasone course or saline placebo for 10 days, using a 2 x 2 factorial design. The primary outcome was death or BPD at 36 weeks' postmenstrual age. Blood gases, ventilator settings, and FiO2 were recorded for 10 days; complications and outcomes were monitored to discharge. The infants' neurodevelopment was evaluated at 18-22 months corrected age.
Mechanical ventilation (MV) of preterm infants with respiratory distress syndrome (RDS) is associated with lung injury and nosocomial infection. Moderately premature infants with mild respiratory distress do not routinely receive artificial surfactant early in their course of treatment. This multi-center, randomized trial tested whether early surfactant therapy and nasal continuous positive airway pressure (CPAP) in infants 1,250-2,000g with RDS reduced mechanical ventilation usage without added complications. Infants with mild to moderate respiratory distress syndrome were enrolled in the trial and given either early administration of surfactant followed by extubation within 30 minutes and the use of CPAP, or standard practice (surfactant according to current center practice, only after initiation of mechanical ventilation), to see whether the experimental method would reduce the need for subsequent mechanical ventilation.
