BACKGROUND: Advances in perinatal care have led to a significant reduction in morbidity and mortality among very-low-birth-weight (VLBW) infants. Much of this progress is related to the prevention and management of respiratory disease. OBJECTIVES: To evaluate changes in perinatal care and its influence on respiratory morbidity and mortality among VLBW infants in Spain in 2 consecutive periods (2002-2006 and 2007-2011). METHODS: This is a retrospective analysis of data prospectively collected of all VLBW infants included in the Spanish SEN1500 network...

INTRODUCTION: Neonatal respiratory disorders are a leading cause of perinatal mortality due to complications resulting from premature births and prenatal exposure to drugs of abuse, but optimal treatments for these symptoms are still unclear due to a variety of confounds and risk factors. Mouse models present an opportunity to study the underlying mechanisms and efficacy of potential treatments of these conditions with controlled variables. However, measuring respiration in newborn mice is difficult and commercial components are expensive and often require modification, creating a barrier and limiting our understanding of the short and long-term effects of birth complications on respiratory function...

Despite the near universal adaptation of gentle mechanical ventilation, surfactant use and non-invasive respiratory support, bronchopulmonary dysplasia (BPD) remains one of the most common respiratory morbidities in very low birth weight (VLBW) infants. Thus, the objective of this review was to evaluate the efficacy of intra-tracheal administration of budesonide-surfactant mixture in preventing bronchopulmonary dysplasia (BPD) in very low birth weight (VLBW) infants. MEDLINE, EMBASE, and PubMed were searched for randomized clinical trials in which intra-tracheal administration of budesonide-surfactant was used to prevent BPD in infants...

BACKGROUND: Hyperoxia is common early in the course of resuscitation of critically ill patients. It has been associated with mortality in some, but not all, studies of cardiac arrest patients and other critically ill cohorts. Reasons for the inconsistency are unclear and may depend on unmeasured patient confounders, the timing and duration of hyperoxia, population characteristics, or the way that hyperoxia is defined and measured. We sought to determine whether, in a prospectively collected cohort of mechanically ventilated patients with traumatic injuries with and without head trauma, higher maximum partial pressure of arterial oxygen (PaO2) within 24 hours of admission would be associated with increased risk of in-hospital mortality...

BACKGROUND: Non-invasive ventilation (NIV) has been used for decades in treatment of exacerbations of chronic obstructive pulmonary disease (COPD). The impact of the changing use of assisted ventilation in acute exacerbations on outcomes has not been fully elucidated and we aimed to describe these changes in the Danish population and describe their consequences for mortality. METHODS: A register-based study was conducted of a cohort of 12,847 patients admitted for acute exacerbation of COPD (AECOPD) from 2004 through 2011, treated with invasive mechanical ventilation (IMV) or NIV for the first time...

REVIEW

BACKGROUND: Previous randomised trials and meta-analyses have shown that nasal continuous positive airway pressure (NCPAP) is a useful method for providing respiratory support after extubation. However, this treatment sometimes 'fails' in infants, and they may require endotracheal re-intubation with its attendant risks and expense. Nasal intermittent positive pressure ventilation (NIPPV) can augment NCPAP by delivering ventilator breaths via nasal prongs. Older children and adults with chronic respiratory failure benefit from NIPPV, and the technique has been applied to neonates...

Electrical impedance tomography (EIT) is an emerging technology for real-time monitoring of patients under mechanical ventilation. EIT has the potential to offer continuous medical monitoring while being non-invasive, radiation-free and low-cost. Due to their ill-posedness, image reconstruction typically uses regularization, which implies a hyperparameter controlling the trade-off between noise rejection and resolution or other accuracies. In order to compare reconstruction algorithms, it is common to choose hyperparameter values such that the reconstructed images have equal noise performance (NP), i...

During mechanical ventilation, patient-ventilator disharmony is frequently observed and may result in increased breathing effort, compromising the patient's comfort and recovery. This circumstance requires clinical intervention and becomes challenging when patients are sedated or verbal communication is difficult. In this work, we propose a brain computer interface (BCI) to automatically and non-invasively detect patient-ventilator disharmony from electroencephalographic (EEG) signals: a brain-ventilator interface...

In central sleep apnoea syndrome (SAS), there is a dysfunction in central ventilatory command. Patients with central SAS can exhibit symptoms and complications linked to unstable sleep caused by apnoea and certain specific mechanisms (chronic and intermittent hypoxia). Central SAS is linked to several diseases which should be investigated before treatment. Treatment depends on underlying conditions and should focus on alleviating symptoms. Possible treatments include nocturnal non invasive ventilation and/or oxygen, and oral medications...

REVIEW

BACKGROUND: There are various reasons why weaning and extubation failure occur, but ineffective cough and secretion retention can play a significant role. Cough augmentation techniques, such as lung volume recruitment or manually- and mechanically-assisted cough, are used to prevent and manage respiratory complications associated with chronic conditions, particularly neuromuscular disease, and may improve short- and long-term outcomes for people with acute respiratory failure. However, the role of cough augmentation to facilitate extubation and prevent post-extubation respiratory failure is unclear...

Analysis of exhaled VOCs can provide information on physiology, metabolic processes, oxidative stress and lung diseases. In critically ill patients, VOC analysis may be used to gain complimentary information beyond global clinical parameters. This seems especially attractive in mechanically ventilated patients frequently suffering from impairment of gas exchange. This study was intended to assess (a) the effects of recruitment maneuvers onto VOC profiles, (b) the correlations between electrical impedance tomography (EIT) data and VOC profiles and (c) the effects of recruitment onto distribution of ventilation...

Bronchopulmonary dysplasia (BPD) is a chronic lung disease most commonly seen in premature infants who required mechanical ventilation and oxygen therapy for acute respiratory distress. While advances in neonatal care have resulted in improved survival rates of premature infants, limited progress has been made in reducing rates of BPD. Lack of progress may in part be attributed to the limited therapeutic options available for prevention and treatment of BPD. Several lung-protective strategies have been shown to reduce risks, including use of non-invasive support, as well as early extubation and volume ventilation when intubation is required...
