Long-term survival following initiation of home non-invasive ventilation: a European study.

Introduction: Although home non-invasive ventilation (NIV) is increasingly used to manage patients with chronic ventilatory failure, there are limited data on the long-term outcome of these patients. Our aim was to report on home NIV populations and the long-term outcome from two European centres.

Methods: Cohort analysis including all patients established on home NIV from two European centres between 2008 and 2014.

Altered synchrony of right ventricular contraction in borderline pulmonary hypertension.

Imaging studies have shown that pulmonary hypertension (PH) is associated with inhomogenous right ventricular (RV) regional contraction, or dyssynchrony, and that this is of prognostic relevance. This study aimed at the identification and functional significance of RV dyssynchrony in borderline PH defined by a mean pulmonary artery pressure between (mPAP) 20 and 25 mmHg. RV dyssynchrony was measured by 2-dimensional speckle tracking echocardiography in 17 patients with pulmonary arterial hypertension (PAH), 13 patients with borderline PH and 14 controls.

A Randomized Controlled Trial on the Effect of Needle Gauge on the Pain and Anxiety Experienced during Radial Arterial Puncture.

Background: Arterial punctures for assessment of arterial blood-gases can be a painful procedure. Lidocaine can be used to reduce pain prior to needle insertion but it is not a widely accepted practice. The purpose of this study was to determine whether a large size needle induces more pain compared to a smaller size needle for radial arterial puncture and to assess the anxiety associated with radial arterial punctures.

Survival of patients with chronic respiratory failure on long-term oxygen therapy and or non-invasive ventilation at home.

Background & Aims: Chronic respiratory failure (CRF) is the common fate of respiratory diseases where systemic effects contribute to outcomes. In a prospective cohort of home-treated patients with CRF, we looked for predictors of long-term survival including respiratory, nutritional and inflammatory dimensions.

Methods: 637 stable outpatients with CRF, 397 men, 68 ± 11 years, on long-term oxygen therapy and/or non-invasive ventilation from 21 chest clinics were enrolled and followed over 53 ± 31 months.

Multimodal nutritional rehabilitation improves clinical outcomes of malnourished patients with chronic respiratory failure: a randomised controlled trial.

Background: In chronic respiratory failure (CRF), body composition strongly predicts survival.

Methods: A prospective randomised controlled trial was undertaken in malnourished patients with CRF to evaluate the effects of 3 months of home rehabilitation on body functioning and composition. 122 patients with CRF on long-term oxygen therapy and/or non-invasive ventilation (mean (SD) age 66 (10) years, 91 men) were included from eight respiratory units; 62 were assigned to home health education (controls) and 60 to multimodal nutritional rehabilitation combining health education, oral nutritional supplements, exercise and oral testosterone for 90 days.

Cephalic versus oronasal mask for noninvasive ventilation in acute hypercapnic respiratory failure.

Objective: Compared to oronasal interfaces, a cephalic mask has a larger inner volume, covers the entire anterior surface of the face and limits the risk of deleterious cutaneous side effects during noninvasive ventilation (NIV). The present clinical study aimed to compare the clinical efficacy of a cephalic mask versus an oronasal mask in patients with acute hypercapnic respiratory failure (AHRF).

Design And Setting: Randomized controlled study in a Respiratory Intermediate Care Unit.

Limitations of transcutaneous carbon dioxide measurements for assessing long-term mechanical ventilation.

Study Objectives: Transcutaneous CO(2) pressure (Ptcco(2)) and transcutaneous O(2) pressure (Ptco(2)) measurements are routinely used in pediatric ICUs in order to avoid serial arterial punctures. The aim of this study was to determine the value of Ptcco(2) assessment during the evaluation of home ventilation in 12 adult patients with COPD or restrictive respiratory failure in the stable state (mean [+/- SD] basal Paco(2), 48.8 +/- 8.
