BACKGROUND: Pleural effusion is frequent in intensive care unit patients, but its impact on the outcome of weaning remains unknown. METHODS: In a prospective study performed in three intensive care units, pleural ultrasound was performed at the first spontaneous breathing trial to detect and quantify pleural effusion (small, moderate, and large). Weaning failure was defined by a failed spontaneous breathing trial and/or extubation requiring any form of ventilatory support within 48 h...

Noninvasive positive-pressure ventilation (NPPV) might be superior to conventional mechanical ventilation (CMV) in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPDs). Inefficient clearance of respiratory secretions provokes NPPV failure in patients with hypercapnic encephalopathy (HE). This study compared CMV and NPPV combined with a noninvasive strategy for clearing secretions in HE and AECOPD patients.The present study is a prospective cohort study of AECOPD and HE patients enrolled between October 2013 and August 2015 in a critical care unit of a major university teaching hospital in China...

Infant delirium is an under-recognized clinical entity in neonatal intensive care, and earlier identification and treatment could minimize morbidities associated with this condition. We describe a case of a 6-month-old former 32 weeks gestation infant undergoing a prolonged mechanical ventilation course diagnosed with delirium related to the combination of his underlying illness and the use of multiple sedative and analgesic mediations. Initiation of the atypical antipsychotic risperidone allowed for weaning from continuous infusions of benzodiazepines and opiods, and lower dosages of bolus-dosed sedation and analgesics...

Automatic tube compensation (ATC) was developed to overcome the flow resistance of endotracheal tube and decrease the imposed work of breathing. Although ATC is used as an evidence-based strategy to predict successful weaning from assisted ventilation, the changes in regional ventilation distribution induced by this technique are not known. We hypothesized that continuous positive airway pressure plus ATC (CPAP+100%ATC) could reactivate the respiratory muscles in patients with prolonged mechanical ventilation (PMV) more effectively than volume assist-control mandatory ventilation (ACMV)...

BACKGROUND: Acute kidney injury in acute critical illness has been associated with poor weaning and survival outcomes. The relation between renal dysfunction as defined by creatinine clearance (CrCl) and weaning from prolonged mechanical ventilation (PMV) is not known. The objective of this study was to determine the relation of measured CrCl to weaning and survival in patients on PMV. METHODS: We retrospectively studied 167 patients on PMV admitted to a long-term acute care facility for weaning over a 3-year period...

BACKGROUND: Metabolic alkalosis (MA) inhibits respiratory drive and may delay weaning from mechanical ventilation (MV). MA is common in CO2-retainer patients that need MV. Acetazolamide (ACTZ) decreases serum bicarbonate concentration and stimulates respiratory drive. This study evaluated the effects of ACTZ on the duration of MV in patients with MA and COPD or obesity hypoventilation syndrome (OHS) intubated with acute respiratory failure. METHODS: Multicenter, randomized, controlled, double-blind study, with COPD or OHS patients with MV < 72 h and initial bicarbonate >28 mmol/L and pH > 7...

BACKGROUND: The reported incidence of necrotising enterocolitis in neonates with complex CHD with ductus-dependent systemic circulation ranges from 6.8 to 13% despite surgical treatment; the overall mortality is between 25 and 97%. The incidence of gastrointestinal complications after hybrid palliation for neonates with ductus-dependent systemic circulation still has to be defined, but seems comparable with that following the Norwood procedure. METHODS: We reviewed the incidence of gastrointestinal complications in a series of 42 consecutive neonates with ductus-dependent systemic circulation, who received early hybrid palliation associated with a standardised feeding protocol...

A 32-year-old motorcyclist who was hit by a tram subsequently presented with blunt force thoracic trauma, a pelvic fracture and a penetrating injury to the left lower extremity. Coagulopathy persisted following surgery of the leg and pelvic vascular intervention. Bedside thoracotomy was performed to treat pneumothorax and pneumopericardium. Severe hypoxemia secondary to lung failure ensued, which required venovenous extracorporeal membrane oxygenation (VV ECMO) support. On the third day after the trauma, ultra-protective mechanical ventilation was not possible due to non-existent lung compliance; thus, the ventilator was disconnected, and the T-piece was connected to the blocked tracheal tube left in the airway...

This study aim was to describe the influences that affect weaning from mechanical ventilation among older adults in the intensive care unit (ICU). Adults older than 65 years comprised only 14.5% of the US population in 2014; however, they accounted up to 45% of all ICU admissions. As this population grows, the number of ICU admissions is expected to increase. One of the most common procedures for hospitalized adults 75 years and older is mechanical ventilation. An integrative review methodology was applied to analyze and synthesize primary research reports...

REVIEW
Darian Ward, Paul Fulbrook
The risks imposed by mechanical ventilation can be mitigated by nurses' use of strategies that promote early but appropriate reduction of ventilatory support and timely extubation. Weaning from mechanical ventilation is confounded by the multiple impacts of critical illness on the body's systems. Effective weaning strategies that combine several interventions that optimize weaning readiness and assess readiness to wean, and use a weaning protocol in association with spontaneous breathing trials, are likely to reduce the requirement for mechanical ventilatory support in a timely manner...

Vanishing lung syndrome is a clinical presentation of giant bullous emphysema associated with significant morbidity and mortality. We present a case of a 50-year-old white woman with vanishing lung syndrome who presented with a spontaneous secondary pneumothorax and an uncontrolled bronchopleural fistula. The large bronchopleural fistula was initially controlled with a double-lumen endotracheal tube and a tube thoracostomy. After surgical efforts failed, complete left lung isolation was performed with multiple intrabronchial valves...

BACKGROUND: Pleural effusion adversely affects the pressuregenerating capacity of the diaphragm. It uncouples the lung and chest wall, which may result in diaphragmatic dysfunction. Information on the effects of effusion drainage on diaphragmatic function is limited, but several studies report relief of dyspnoea after drainage, which was attributed to improved diaphragmatic mechanics, even if this issue was never formally addressed. OBJECTIVE: To investigate the effect of drainage of unilateral pleural effusion on diaphragmatic function...

BACKGROUND: For patients requiring prolonged mechanical ventilation (PMV), weaning is difficult and mortality is very high. PMV has been defined recently, by consensus, as constituting ≥21 consecutive days of mechanical ventilation (MV) for ≥6 hours per day. This study aimed to evaluate the clinical factors predicting weaning failure in patients undergoing PMV in medical intensive care unit (ICU). METHODS: We retrospectively reviewed the clinical and laboratory characteristics of 127 patients who received MV for more than 21 days in the medical ICU at Chonnam National University Hospital in South Korea between January 2005 and December 2014...
