A Central and Eastern European Survey on PEEP Titration and Alveolar Recruitment Manoeuvres During General Anaesthesia
Lung protective mechanical ventilation (LPV) is associated with a lower incidence of postoperative pulmonary complications (PPC). The pathophysiology of ventilator-induced lung injury and the risk factors of PPCs have been widely identified, and a perioperative lung protective concept has been elaborated in the past decades. The three main basic elements of LPV are application of low tidal volumes (TV < 6mL/kg), use of optimal levels of PEEP and regular alveolar recruitment manoeuvres. Despite growing evidence recent studies indicated that the entire intraoperative LPV concept is still not widely implemented in current anaesthesia practice even in high-risk surgical patients. However the use low TV is common, either PEEP individualization, or regular ARM are usually ignored, moreover these elements were considered unnecessary or even harmful and their reason is questioned from time to time.
Dear Colleague,
You are being invited to participate in a research study titled "A Central and Eastern European Survey on PEEP Titration and Alveolar Recruitment Manoeuvres During General Anaesthesia". This study is being done by Zoltán Ruszkai MD from Péterfy Hospital, Budapest, and Professor Zsolt Molnár from Szeged, Hungary.

The aim of this questionnaire-based survey is to evaluate the routine use of individual PEEP and regular ARM of Central and Eastern European anaesthesiologists during general anaesthesia, and will take you approximately 10 minutes to complete.

Duration of the survey: 01/08/19 - 30/09/19
Ethics Committe Approval: Hungarian Medical Research Council, 30155-2/2019/EKU
ClinicalTrials.gov Identifier: NCT04030078

Your participation in this study is entirely voluntary and anonymous. Neither sensitive personal data nor contact information will be collected during the research. We believe there are no known risks associated with this research study; however, as with any online related activity the risk of a breach is always possible.

This research does not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors, and the investigators declare that they do not have any conflict of interest with the work.

If you need further information, you are free to omit any question. Please send an e-mail to:


Thank you for participating in our survey!
