Non-invasive ventilation practice in Moroccan ICUs and EDs: a survey of practitioners

Abstract

Introduction: Non-invasive ventilation (NIV) is a long-standing therapy used in emergencies and resuscitation. The objective of our
work was to evaluate the prevalence of NIV practice, mastery of settings, indications and criteria of failure in Moroccan settings.
Materials and methods: A first part of the practitioners was interviewed by a self-administered questionnaire during the congress
of the Moroccan Society of Anesthesia, Analgesia and Critical Care held in January 2018. A second part was interviewed by an
electronic questionnaire. It included demographic characteristics, methods of implementing NIV, indications and failure criteria.
Results: Among the 800 questionnaires distributed, we collected 183 responses with a participation rate of 23 %. The majority
of participants (88 %) claimed to have practiced NIV. PSV-PEEP mode was preferred in 70 % of cases. Cardiogenic pulmonary
edema and decompensation of chronic obstructive pulmonary disease were retained as first indications to the setting up. A
protocol existed in only 5 % of the structures. The NIV is used more by anesthetists and intensivists and in university hospitals
and private clinics.
Conclusion: NIV is a technique used routinely in emergencies. Its indications and tuning parameters conformed to the consensus
conference; however, the lack of protocol can hinder the start up
