Single lung ventilation

B A McGrath, S Ruane, J McKenna, S Thomas
Disposable bronchoscopes such as the Ambu aScope(TM) 3 are marketed as 'single use' The risks of contamination from prolonged device storage before possible re-use are unknown. Following clinical bronchoscopy in patients whose lungs were mechanically ventilated, 20 aScope(TM) 3's bronchoscopes received a standard 'social clean' and were then stored. Subsequent paired saline flush and swab samples were taken at time zero, and at 24 h and 48 h. Positive microbiological cultures were obtained from at least one time point from 16 of the 20 bronchoscopes...

Congenital airway pulmonary malformations are increasingly being diagnosed, but their management continues to remain controversial. Our approach has been to offer surgery to mitigate the risk of infection and possible malignancy. All patients routinely undergo a CT scan of the chest postnatally and once the diagnosis is confirmed, minimal access surgery is offered. Our anesthetists provide single-lung ventilation to enhance the operative view. We conducted a retrospective review over a 10-year period, during which 91 patients were prenatally suspected to have a cystic lung lesion...

Hypoxic pulmonary vasoconstriction (HPV) is a homeostatic mechanism that is intrinsic to the pulmonary vasculature. Intrapulmonary arteries constrict in response to alveolar hypoxia, diverting blood to better-oxygenated lung segments, thereby optimizing ventilation-perfusion matching and systemic oxygen delivery. In response to alveolar hypoxia, a mitochondrial sensor dynamically changes reactive oxygen species and redox couples in PASMC. This inhibits potassium channels, depolarizes PASMC, activates voltage-gated calcium channels, and increases cytosolic calcium, causing vasoconstriction...

BACKGROUND: The T-piece resuscitator (TPR) is in common use worldwide to deliver positive pressure ventilation during resuscitation of infants <10 kg. Ease of use, ability to provide positive end-expiratory pressure (PEEP), availability of devices inbuilt into resuscitaires and cheaper disposable options have increased its popularity as a first-line device for term infant resuscitation. Research into its ventilation performance is limited to preterm infant and animal studies. Efficacy of providing PEEP and the use of TPR during term infant resuscitation are not established...

For patients with lung cancer undergoing curative intent radiotherapy, functional lung imaging can be incorporated into treatment planning to modify the dose distribution within non-target volume lung by differentiation of lung regions that are functionally defective or viable. This concept of functional image-guided lung avoidance treatment planning has been investigated with several imaging modalities, primarily single photon emission computed tomography (SPECT), but also hyperpolarised gas magnetic resonance (MR) imaging, positron emission tomography (PET) and computed tomography (CT)-based measures of lung biomechanics...

BACKGROUND: Respiratory weakness and spinal deformity are common in patients with spinal muscular atrophy (SMA). Posterior (distraction type) growing rods have recently gained favor as a treatment option in this population, due to their ability to prevent spinal deformity progression and their potential to allow lung volumes to increase over time. The objective of this study was to determine the impact of posterior growing rods on the spinal alignment and respiratory function in children with SMA with intermediate term follow-up...

Diagnostic imaging plays an integral role in the diagnostic workup of suspected pulmonary embolism, and several modalities have been employed over the years. In recent years, the choice has been narrowed to either computer tomographic or radionuclide based methods, i.e. computer tomographic angiography (CTA) and ventilation-perfusion scintigraphy (V/Q-scan). Both methods display advantages and shortcomings, and while we provide some insights into CTA and alternative methods, the paper's main focus is a review of the V/Q-scan...

PURPOSE: We hypothesized that the ventilator-related causes of lung injury may be unified in a single variable: the mechanical power. We assessed whether the mechanical power measured by the pressure-volume loops can be computed from its components: tidal volume (TV)/driving pressure (∆P aw), flow, positive end-expiratory pressure (PEEP), and respiratory rate (RR). If so, the relative contributions of each variable to the mechanical power can be estimated. METHODS: We computed the mechanical power by multiplying each component of the equation of motion by the variation of volume and RR: [Formula: see text]where ∆V is the tidal volume, ELrs is the elastance of the respiratory system, I:E is the inspiratory-to-expiratory time ratio, and R aw is the airway resistance...

INTRODUCTION: Patients with severe pulmonary hemorrhage due to unilateral trauma or a bleeding cancer often present to the emergency department in acute respiratory distress. Although it is generally recommended to perform single lung intubation, most emergency department providers do not have access to or are not familiar with double-lumen endotracheal tubes, and blind insertion of an endotracheal tube to maximum depth does not ensure that the proper (nonhemorrhagic) lung is ventilated...

Minimally invasive and hybrid minimally invasive esophagectomy (MIE) is a technically challenging procedure. Anesthesia for the same is equally challenging due to special requirements of the video-assisted thoracoscopic technique used and shared operative and respiratory fields. Standard ventilatory strategy for this kind of surgery has been 1-lung ventilation with the help of a double-lumen tube. Prone positioning for thoracoscopic dissection facilitates gravity-dependant collapse of the operative side lung induced by a unilateral capnothorax, thus making the use of single-lumen endotracheal tube a feasible option for this surgery...

PURPOSE: Acute respiratory distress syndrome is a life-threatening form of respiratory failure without an established pharmacological treatment. Recently, macrolides have been found to be beneficial in cases of acute lung injury, but evidence is limited. MATERIALS AND METHODS: This single-centre retrospective cohort evaluation of hospitalized patients with sepsis-associated acute respiratory distress syndrome aimed to assess the impact of azithromycin on clinical outcomes by using a propensity score analysis...

Diagnosis and treatment of many lung diseases like cystic fibrosis (CF) or chronic obstructive pulmonary disease (COPD) could benefit from 3D ventilation information. Applying two EIT systems concurrently is a simple approach without specialized hardware that allows monitoring of regional changes of ventilation distribution inside the thorax at different planes with the high temporal resolution much valued in common single plane EIT. Effects of two simultaneously operated EIT devices on one subject were investigated to monitor rapid processes inside the thorax with a multi-plane approach...

BACKGROUND: Pseudomonas aeruginosa (PA) is the single-most common pathogen of ventilator-associated pneumonia (VAP). Large quantities of PA in the trachea of ventilated patients are associated with an increased risk of death. However, the role of PA colonization in PA VAP-induced lung injury remains elusive. This study examined the effect and mechanism of PA colonization in VAP-induced lung injury. METHODS: C57BL/6 wild-type (WT) and c-Jun N-terminal kinase knockout (JNK1(-/-)) mice received mechanical ventilation for 3 h at 2 days after receiving nasal instillation of PA (1 × 10(6) colony forming unit) or normal saline...

Dual-energy computed tomography (DECT) angiography of the chest provides a combined morphological and functional analysis of the lung, usually obtained in a single acquisition without extra radiation or injection of extra intravenous iodine contrast. The parenchymal iodine maps generated by DECT are well correlated with scintigraphy, and are becoming an essential tool for evaluating patients with pulmonary vascular diseases. With a single DECT acquisition, complete imaging of pulmonary hypertension is now available, displaying vascular anatomy, parenchymal morphology and functional assessment...

OBJECTIVES: Bronchiolitis obliterans syndrome (BOS) is a serious late complication following allogeneic haematopoietic stem cell transplantation (allo-HSCT) and is associated with chronic graft-versus-host disease. However, the outcome of medical treatment for BOS, mainly immunosuppressive therapy, is disappointing. This study evaluated the early outcomes of lung transplantation (LTx) as a treatment option for severe BOS. METHODS: Between January 2010 and December 2014, we retrospectively reviewed the medical records and postoperative outcomes of 9 patients who underwent LTx for BOS after allo-HSCT at a single institution...
