Efficacy of Morphine in Reducing the Rate of Early Non-Invasive Ventilation Failure in Acute Exacerbation of Chronic Obstructive Pulmonary Disease, Phase I/IIa
Recruiting now · Phase 1/Phase 2
Conditions studied: Chronic Obstructive Pulmonary Disease
In brief
Acute exacerbations of Chronic Obstructive Pulmonary Disease (COPD) are a major source of morbidity and mortality for patients and cost to the society. In case of acute respiratory failure with hypercapnia and acidosis, Non Invasive Ventilation (NIV) is preferred as a first line treatment. NIV failures are not uncommon, from 15% in intensive care to 25 - 30% in emergency departments. They most often occur at the start of the NIV or in the hours that follow. There are many reasons for these failure. Among these are; dyspnea, discomfort, the pain related to the exacerbation and also to the NIV are frequently noted. The use of certain drugs with anxiolytic, hypnotic and/or analgesic properties could also be useful. Some sedatives and opioids have already been studied in this indication but without a therapeutic trial and satisfactory methodology. Among the molecules of interest, Morphine seems interesting . It's administration could reduce the ventilatory rate, intensity of dyspnea, pain and anxiety as well as dynamic hyperinflation. The investigators believe that morphine administration will decrease the rate of early NIV failure by improving comfort (decreased dyspnea and pain) and ventilation (decreased respiratory rate and increase in tidal volume) in patients with exacerbations of COPD. However, before considering a randomized phase III efficacy study, it is necessary to determine the optimal dose of morphine in this indication, through a phase I/II dose-finding study taking into accounts both the efficacy and toxicity of morphine. The main objective of this study, is to determine the optimal dose of morphine administered at the initiation of NIV in patient with acute Exacerbation of Chronic Obstructive Pulmonary Disease (COPD), which is defined as the maximum gain function combining the probability of dose-limiting toxicity with PaCO2.Therefore, the impact of morphine administration on the physiological parameters of NIV- COPD exacerbation patients will be assessed.

You may not qualify if…
- Patient already treated by NIV during admission (e. g. introduction in pre-hospital by SMUR) or started more than one hour ago in the department.
- Sedative (barbiturates, benzodiazepines and related substances and other sedatives) or morphine treatment within 24 hours before inclusion
- Chronic alcoholism
- Contra-indication to NIV: disturbances of consciousness (Glasgow < 11) except moderate hypercapnic encephalopathy; indication of immediate intubation; risk of inhalation; sputum impossible; hemodynamic instability; inability to remove the mask; trauma, surgery or facial malformation; patients with pH < 7.25 can only be included in intensive care unit or in the vital emergency room of the emergency department, under continuous monitoring
