Influence of different interfaces on synchrony during pressure support ventilation in a pediatric setting: a bench study

2015

BACKGROUND: In adults and children, patient-ventilator synchrony is strongly dependent on both the ventilator settings and interface used in applying positive pressure to the airway. The aim of this bench study was to determine whether different interfaces and ventilator settings may influence patient-ventilator interaction in pediatric models of normal and mixed obstructive and restrictive respiratory conditions. METHODS: A test lung, connected to a pediatric mannequin using different interfaces (endotracheal tube [ETT], face mask, and helmet), was ventilated in pressure support ventilation mode testing 2 ventilator settings (pressurization time [Timepress]50%/cycling-off flow threshold [T…

New organisation for follow-up and assessment of treatment efficacy in sleep apnoea.

2019

Obstructive sleep apnoea (OSA) is a highly prevalent disease, and there is an increased demand for OSA diagnosis and treatment. However, resources are limited compared with the growing needs for OSA diagnosis and management, and alternative strategies need to be developed to optimise the OSA clinical pathway. In this review, we propose a management strategy for OSA, and in general for sleep-disordered breathing, to be implemented from diagnosis to follow-up. For this purpose, the best current options seem to be: 1) networking at different levels of care, from primary physicians to specialised sleep laboratories; and 2) use of telemedicine. Telemedicine can contribute to the improved cost-ef…

Initial topical cooling followed by backtable Celsior flush perfusion provides excellent early graft function in porcine single lung transplantation …

2013

Topical in situ cooling of the donor lungs is a prerequisite for procurement of non-heart-beating donor lungs and may be of interest for living related lung donation.Twenty-four single lung transplants were performed in 4 groups of Landrace pigs (6 per group). Control LPD, control Celsior and topical cooling in situ, followed by LPD (exLPD) or Celsior (exCel) ex situ flush, were employed. All lungs were perfused antegrade with 1 liter of solution at 4°C. Lungs were stored immersed in preservation solution for 24 hours at 4°C. After transplantation of the left lung, the right recipient bronchus and pulmonary artery were clamped.Four of 6 animals each in the LPD and Celsior groups and all 6 a…

Tuberculosis Following Lung Transplantation. A 27-Year Spanish Multicenter Experience. Incidence, Presentation, Prevention and Treatment with Rifampi…

2020

Abstract Background Tuberculosis (TB) represents a diagnostic and therapeutic challenge for solid organ transplant recipients, particularly after lung transplant (LT). Our aim was to determine the impact of TB in LT patients in Spain, considering prevalence, clinical presentation, prevention and therapeutic management. In addition, differences in outcome between rifampicin (RIF) versus non-RIF containing regimens were analyzed. Methods Multicenter, observational retrospective study, including all cases of TB diagnosed in recipients after LT, in five pulmonary transplant units in Spain, between January 1990 and December 2017. Results Among 2962 LT recipients, 45 cases of TB were diagnosed, r…

German Thoracic Research Scholarship 1996: lung volume reduction for endstage pulmonary emphysema at the Washington University of St. Louis.

1998

The Thoracic Research Scholarship 1996 of the German Society for Thoracic and Cardiovascular Surgery enabled me to visit Barnes Hospital at the Washington University of St. Louis, USA, from May to July 1996. At that center Prof. J. D. Cooper has established lung-volume reduction surgery as a successful surgical treatment for patients with endstage pulmonary emphysema. The operation is performed using left-sided double-lumen intubation. After opening of the chest and pleura and starting single-lung ventilation the less diseased parts of the second lung collapse due to absorption atelectasis whereas the more diseased portion of the lung stays hyperinflated. Linear staplers buttressed with bov…

Lung Function Monitoring; A Randomized Agreement Study

2016

Objective: To determine the agreement between devices and repeatability within devices of the forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF) and forced expiratory flow at 50% of FVC (FEF50) values measured using the four spirometers included in the study. Methods: 50 (24 women) participants (20-64 years of age) completed maximum forced expiratory flow manoeuvres and measurements were performed using the following devices: MasterScreen, SensorMedics, Oxycon Pro and SpiroUSB. The order of the instruments tested was randomized and blinded for both the participants and the technicians. Re-testing was conducted on a following day within 72 hours …

Is an activity volume threshold really realistic for lung cancer resection?

2018

IF 1.804 (2017); International audience; Background:We analyzed volume as a continuous variable to estimate threshold, which is a methodology rarely seen in the literature. The objective of this work was to assess hospital volume for lung cancer (LC) surgery and to establish the associated threshold for acceptable in-hospital mortality (IHM). Data was obtained from the French national medico-administrative database.Methods:From January 2005 to December 2016, data from 108,571 patients operated for LC in France were collected from the national administrative database. To estimate the volume threshold, hierarchical logistic regression models were developed.Results:The crude IHM rate was 5.2% …

Congenital pulmonary airway malformation in adult: report of two rare cases and literature review

2019

Congenital pulmonary airway malformations (CPAMs) are a heterogeneous group of congenital, non-hereditary lesions of the lung, cystic and non-cystic type with clear developmental anomalies and evident malformative changes, which derive from the excessive proliferation of the tubular bronchial structures. We described two rare cases of type IV CPAM detected in adult patients with different clinical presentation: one of these cases was symptomatic, complaining of cough and hemoptysis. Conversely, the other case was reported as incidental findings in patient with abdominal pain without respiratory symptoms. Chest computed tomography (CT) scan was performed showing voluminous cystic formations …

Plexiform Vasculopathy in Chronic Thromboembolic Pulmonary Hypertension

2017

2021

BACKGROUND The aim of this study was to identify risk factors for surgical complications after anatomic lung resections in the era of video-assisted thoracic surgery (VATS) and enhanced recovery after surgery (ERAS). METHODS A retrospective analysis of all consecutive adult patients who underwent elective anatomic lung resections between January and December 2020 at our institution was performed. RESULTS Eighty patients (40 VATS, 40 thoracotomy) were included. The 30-day mortality rate was 1.3%. The overall rate of major postoperative complications was 18.8%. Most major complications occurred in patients who underwent open surgery (complication rate 32.5%, share of total complications 86.7%…
