Chronic fetal hypoxaemia is a common pregnancy complication that may arise from maternal, placental and/or fetal factors. Respiratory outcome of the infant at birth likely depends on the duration, timing and severity of the hypoxaemic insult. We have isolated the effect of maternal chronic hypoxia (MCH) for a month in late gestation on fetal lung development. Pregnant ewes were exposed to normoxia (21% O2 ) or hypoxia (10% O2 ) from 105-138 d gestation (term ∼145 d). At 138 d, gene expression in fetal lung tissue was determined by qRT-PCR...

OBJECTIVES: Pulmonary lymphangiectasia associated with hypoplastic left heart syndrome with an intact or restrictive atrial septum may result from increased left atrial pressure, and is associated with worse outcomes following staged reconstruction due to lung dysfunction and significant hypoxaemia. Our objective was to characterise the incidence of pulmonary lymphangiectasia in cases of early mortality following stage 1 reconstructions. METHODS: An institutional cardiac surgical database was retrospectively searched for patients who died within 30 days following a stage 1 reconstruction between 1 January, 1984 and 31 December, 2013...

Little is known about the mechanisms causing tremors during immobilisation of rhinoceros and whether cardiorespiratory supportive interventions alter their intensity. Therefore, we set out to determine the possible mechanisms that lead to muscle tremors and ascertain whether cardiorespiratory supportive interventions affect tremor intensity. We studied tremors and physiological responses during etorphine-azaperone immobilisation in eight boma-held and 14 free-living white rhinoceroses. Repeated measures analysis of variance and a Friedman test were used to determine differences in variables over time and between interventions...

BACKGROUND AND AIMS: Various anaesthetic drugs, in addition to airway block, are used for producing favourable intubation conditions during awake fibre-optic intubation (AFOI), but most of them cause respiratory depression and hypoxaemia. The aim of this study was to evaluate the efficacy of intravenous (IV) dexmedetomidine (DEX) on sedation, patient comfort and cardiovascular responses during AFOI in patients with cervical spondylotic myelopathy (CSM). METHODS: This randomised, placebo-controlled, double-blinded, prospective study was conducted on 56 adult patients with cervical spondylotic myelopathy (CSM) undergoing elective cervical fixation, who were randomly allocated into two groups - Group D and Group C...

BACKGROUND AND OBJECTIVE: Clinical and epidemiological cohort studies have shown that obstructive sleep apnoea (OSA) is a common but largely undiagnosed disorder in senior subjects, where progressive deterioration of the pathology would be expected as a consequence of the ageing processes. Our study examines the longitudinal progression of OSA over a 7-year period in a community-based sample of healthy subjects. METHODS: The sample consisted of 284 volunteers, aged >65 years (52% women, 48% men) accepting clinical and instrumental follow-up at 7 years...

Muscular dystrophy is a group of inherited myopathies characterised by progressive skeletal muscle wasting, including of the respiratory muscles. Respiratory failure, i.e. when the respiratory system fails in its gas exchange functions, is a common feature in muscular dystrophy, being the main cause of death, and it is a consequence of lung failure, pump failure or a combination of the two. The former is due to recurrent aspiration, the latter to progressive weakness of respiratory muscles and an increase in the load against which they must contract...

Isolated right superior caval vein drainage into the left atrium is a rare congenital cardiac anomaly usually presenting with hypoxaemia and cyanosis. Surgical repair is the definitive treatment for this condition. In this report, we present the case of a 72-year-old patient with uncorrected anomalous drainage of a right superior caval vein into the left atrium, first diagnosed in the 1960s. To the best of our knowledge, this is the oldest reported unrepaired case.

PURPOSE: To provide evidence-based guidelines for early enteral nutrition (EEN) during critical illness. METHODS: We aimed to compare EEN vs. early parenteral nutrition (PN) and vs. delayed EN. We defined "early" EN as EN started within 48 h independent of type or amount. We listed, a priori, conditions in which EN is often delayed, and performed systematic reviews in 24 such subtopics. If sufficient evidence was available, we performed meta-analyses; if not, we qualitatively summarized the evidence and based our recommendations on expert opinion...

BACKGROUND: Air travel may imply a health hazard for patients with cystic fibrosis (CF) due to hypobaric environment in the aircraft cabin. The objective was to identify pre-flight variables, which might predict severe hypoxaemia in adult CF patients during air travel. METHODS: Thirty adult CF-patients underwent pre-flight evaluation with spirometry, arterial oxygen tension (PaO2), pulse oximetry (SpO2) and cardiopulmonary exercise testing (CPET) at sea level (SL)...

When immobilising wildlife, adverse side effects can include hypoxaemia, acidosis and hypertension. Pulmonary gas exchange and acid-base status were evaluated during immobilisation of 25 free-ranging and one boma-held black rhinoceros (Diceros bicornis) in Zimbabwe. The effect of different body positions on arterial oxygenation was evaluated. A combination of the following drugs was used: an opioid (etorphine or thiafentanil), azaperone and an a2 -adrenoceptor agonist (detomidine or xylazine). Respiratory and heart rates, rectal temperature and pulse oximetry-derived haemoglobin oxygen saturation were recorded...

AIMS: Obstructive sleep apnea syndrome (OSAS) is associated with increased cardiovascular risk and diabetes independent of obesity. We investigated whether adipose tissue dysfunction is exacerbated due to increased tissue hypoxia. METHODS: Adipose tissue (AT) oxygenation was measured with a Clarke-type electrode (pATO2) in 16 men with OSAS before and after 4 months of continuous positive airway pressure therapy (CPAP) and in BMI-matched controls. Oxygenation was simultaneously monitored in arterial blood by pulse oximetry (SaO2); mixed blood in AT microcirculation by reflectance spectroscopy (SATO2) along with blood flow...

A previously healthy young man with a rare genetic condition presented with severe acute respiratory distress syndrome secondary to pneumonia with septic shock. He did not improve with conventional therapy for his known causal organism thus prompting further workup. He was found to be profoundly immunosuppressed raising our suspicion for atypical organisms. A bronchoalveolar lavage sample was positive via PCR for adenovirus which we suspect exacerbated a pre-existing bacterial pneumonia and led to a severe and non-responsive respiratory failure...

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...
