Evolving to a single inhaler extrafine LABA/LAMA/ICS - Inhalation technique and adherence at the heart of COPD patient care (TRIVOLVE).

OBJECTIVE: Incorrect inhaler use and poor treatment adherence have a negative impact on COPD outcomes. This multi-centre, single arm, non-interventional, phase IV study investigated whether inhalation technique, treatment adherence and patient outcomes change in patients who evolve from dual therapy or multiple inhaler triple therapy to single inhaler extrafine triple therapy (beclomethasone dipropionate (BDP, 87 µg), formoterol fumarate (FF, 5 µg) and glycopyrronium (G, 9 µg)) in combination with inhalation technique training. METHODS: A total of 126 COPD patients were included in the per protocol set. Inhalation technique and treatment adherence were assessed at baseline and at two visits at approximately 3 and 6 months of treatment with extrafine BDP/FF/G. In addition, lung function, symptom score, patient satisfaction and exacerbations (exploratory) were followed up. RESULTS: Before switching to single inhaler extrafine BDP/FF/G (baseline), any device errors and critical errors were detected for 28.8% and 9.6% of patients, respectively. After switching to BDP/FF/G, the percentage of patients with any device errors decreased to 14.0% (visit 2) and 16.3% (visit 3), without critical errors at the two follow-up visits. Treatment adherence increased from 67.5% at baseline to 75.8% (visit 2) and 80% (visit 3). In addition, lung function, symptom and patient satisfaction scores improved, whilst exacerbation rates substantially decreased. CONCLUSIONS: This observational study demonstrates that in eligible COPD patients in a real-life setting, the switch from dual therapy or multiple inhaler triple therapy to single inhaler extrafine BDP/FF/G in combination with inhalation technique training is associated with improved inhalation technique and adherence.

Influence of chest physiotherapy on arterial oxygen saturation.

Two groups of ventilated patients were compared for chest physical therapy on an ICU: respiratory insufficient patients on one side and a control population on the other were submitted either to percussion or vibration therapy, and to postural drainage. Our data show a decrease in arterial oxygen saturation after CPT and after 2h monitoring; the lateral position results in a better SaO2 in the pneumonia group while SaO2 tend to decrease in the control population. However, no significant therapeutic influence of vibration nor percussion was found. Our data suggest CPT does not result in a short term respiratory benefit. Further investigations with prolonged sessions of postural drainage are required.

Propofol for arthroscopy in outpatients. Comparison of three anaesthetic techniques.

Sixty unpremedicated adult patients, undergoing arthroscopy, received propofol 2 mg kg-1 for induction of anaesthesia, before random allocation to three groups receiving one of the following: a continuous infusion of propofol supplemented with nitrous oxide in oxygen (group I); isoflurane and nitrous oxide in oxygen (group II); a continuous infusion of propofol in combination with repeated bolus doses of alfentanil (group III). The results showed no major differences in cardiovascular variables between the groups. Ventilation rate was highest in group II. Early recovery was less smooth and showed slight impairment in group III compared with the other groups. The data suggest that induction of anaesthesia with propofol followed by maintenance with isoflurane or continuous infusion of propofol is preferable for this procedure.
