Objectives: Incidence and management of positive pressure non-invasive ventilation (NIV) in intensive care unit (ICU) in the postoperative period.
Study design: Phoning study performed on September 2001 in 60 ICU of south of France (public: 47, private: 13, medical: 11, surgical: 20, medical-surgical: 29), which were randomized from a national list.
Results: NIV was used currently on 55% and casually on 35% of the units. Ten percent of ICU, which never use NIV, were surgical on 83% with a lower number of bed (7 +/- 3 vs. 12 +/- 5). The most often humidification device used was a Heat and Moisture Exchanger (HME) (52%), a Heated Humidifier (HH) (26%), either (4%) and none device (19%). ICU that never used a humidification device used a home ventilator in 30%. Ventilators used were more often heavy ICU ventilators (80%) with a facial mask (89%). NIV was performed exclusively by physicians in 15% of cases and in collaboration after the first application in 71% of cases. Sixty-nine % of intensivists used NIV as a first choice for the treatment of acute postoperative respiratory failure and 54% of intensivists for the treatment of postoperative atelectasis.
Conclusion: Use of NIV increases in ICU, particularly in surgical units. Practices are different between ICU. An HME is the most frequently humidification device used.
